Definitions
- This invention relates to improvements in machines for applying pressure to shoe bottoms and is herein illustrated as embodied in a machine of the type disclosed in Letters Patent of the United States No. 2,047,185, granted July 14, 1936', in the name of Milton 1-1. Ballard et al.
- the machine is provided with a rotary turret arranged to rotate in a horizontal plane and carrying a plurality of pad boxes mounted on the turret with their longer axes extending in the direction of its rotation.
- the pad boxes are provided with shoe receiving pads and each pad box has associated with it a set of sole and shoe positioning mechanism for relatively positioning soles and shoes placed on its pad.
- each pad box for relatively locating the heel ends of a sole and shoe mounted on the pad comprises a sole locating pin adapted to enter a hole in the center of the heel portion of the sole, a heel fork member having diverging faces for engaging the opposite sides of the heel end of the shoe, and mechanism for moving the pin, while engaging the sole, laterally of the shoe to move the sole into the desired position relatively to the heel end of the shoe.
- This sole, and shoe positioning mechanism is particularly arranged for operating on womens shoes in which the heel portions of the soles are usually of a relatively thin and flimsy construction which does not permit the soles to be easily positioned relatively to the shoeby members such as gage fingers adapted to engage the opposite edge portions of the soles.
- the pad boxes In order to adapt thepad boxes for operating on mens shoes in which the soles are relatively thick and the heel portions of which have no hole therein for receiving the sole locating pin above referred to, the pad boxes have been redesigned in the manner disclosed in Letters Patent of the United States No. 2,005,755, granted June 25, 1935 on an application filed in the name of Francis J. Better and in Letters Patent of the United States No. 2,063,041, granted December 8, 1936 in the name of Floyd G. Knowles.
- the sole and shoe positioning mechanism for operating on the heel ends of mens shoes comprises a pair of sole locating gages or fingers for engaging the opposite edges of the heel end of a mans relatively thick sole and a similar pair of gages or fingers for engaging the opposite sides of a mans shoe, these gages being held against movement away from the sole and shoe after they have contacted therewith and operating to move the sole and shoe relatively to each other and thus to bring their heel end portions into proper alinernent with each other.
- An object of the present invention is to provide for use in a machine of the type referred to a pad box having sole and shoe positioning mechanism mounted thereon that will operate efiicient ly and with substantially equal facility on shoes that vary widely in size and style, for example, on womens shoes having relatively flimsy soles with sole locating holes in their heel portions, and also on mens shoes having relatively thick soles with no holes in their heel portions.
- Another object of the invention is to provide an improved arrangement which will eliminate the possibility of a thin flimsy sole being cemented to a shoe in a twisted or otherwise distorted condition.
- a further object of the invention' is to provide improved means for withdrawing from operative position those sole and shoe positioning members or gages which might tend to injure either the sole or the shoe by remaining in engagement therewith as the sole and shoe are forced against the pad by pressure exerted on the shoe by the machine.
- an illustrative embodiment of the invention comprises a pad box containing a pad and having forepart positioning mechanism similar to that disclosed in the Ballard et a1.
- patent referred to except that only one pair of forepart gages is utilized in the present construction.
- Heel end locating or gaging means for a shoe is provided similar in some respects to that disclosed in the said Ballard et al. patent and similar in other respects to that disclosed in the Better patent above referred to.
- heel end sole locating gages or fingers in the present construction are, in accordance with one feature of the invention, capable of being slid, relatively to their actuating mechanism, lengthwise of the pad box to enable them to engage both large and small soles and the heel end locating means for the shoe is also capable of sliding lengthwise of the pad box to enable it to operate easily on shoes of varying sizes.
- the illustrated pad box is provided with pivotally mounted supporting means for a pin for engaging a hole in the heel end of a sole for a womans shoe and this pin is arranged to be readily movable out of operative position when it is desired to position a sole for a mans or a childs shoe on the pad, which sole has no locating hole in its heel portion and which, accordingly, is located with the aid of sole locating gages or fingers.
- the illustrated arrangement is such that when the sole locating pin is in a position for operating on a sole for a womans shoe it, and the heel portion of the sole which it engages, will occupy such a position lengthwise of the pad that they will be spaced from the locating fingers for operating on mens soles so that the fingers will not be in a position to foul the pin or the sole even though they are actuated idly by their actuating mechanism when the pin is in use.
- the heel end locating mechanism for the shoe and the sole locating pin and the gage fingers are all mounted in such a manner as to allow them to be moved as a unit widthwise of the pad after they have positioned the heel ends of the shoe and sole thereon, thereby enabling the operator to straighten the sole, if necessary, or to remove from its shank portion any wrinkles or creases which may have been formed therein owing to the sole having been initially placed on the pad in a somewhat twisted condition.
- a further featureiof the invention resides in the provision of means for automatically withdrawing from operative position and looking or latching in their withdrawn position any sole and shoe gages or fingers which, by their engagement with the sole or shoe during the pressure applying operation, might tend to injure the latter as they are pressed against the pad.
- the gage withdrawing means is fluid pressure controlled by the hydraulic mechanism of the machine disclosed in the Ballard et al. patent for applying pressure to the sole and shoe and the arrangement is such that the withdrawal and latching of the gages is not 'efiected until after sufficient pressure has been applied to the sole and shoe to insure that they will not become displaced relatively to each other by further pressure applied after the gages are withdrawn.
- Fig. 1 is a front elevation of a pad box embodying the present invention
- Fig. 2 is a plan View of the pad box
- Fig. 3 is a right-hand end View of the pad box on a larger scale and the shoe and sole heel locating means associated therewith;
- Fig. 4 is .a side elevation of mechanism for withdrawing certain of the shoe and sole locating means from operative position prior to the application of the full pressure on the sole and shoe.
- the pad box illustrated herein is similar, in certain respects, to that disclosed in the Ballard et al. patent aforementioned and comprises left and right-hand portions or sections In and I 2 pivoted together about an axis I4 located substantially at the mid-portion of the pad box.
- Means including an arcuate notched block [6 and a co-operating and withdrawable latch-bolt l8 are provided for retaining the forepart section ID of the pad box in any desired angular position into which it may be adjusted about the axis M.
- the section IU of the pad box carries forepart gaging mechanism including a pair of sole locating fingers (Fig. 2) and shoe locating fingers 22 carried by arms 24 similar to those referred to in the Ballard et al.
- these arms being pivoted for free vertical movement on pivots 26 carried by members 28 (Fig. 2) which in turn are pivoted at 30 on the section In.
- the fingers 20 and 22 are supported by blocks formed on stems 32 which are adjustably clamped in the arms 24 by bolts 34 passing through split portions of the arms.
- the fingers 20 and 22 are adjustable lengthwise of the arms 24 by movement of the stems 32 in the arms to vary their positions for operating on shoes which differ appreciably in length, thereby permitting the fingers to engage the opposite sides of a shoe and a shoe on a pad 36 in the pad box at the desired position, which is preferably at, or a little toeward of, the tip line of the shoe.
- These fingers are arranged to be swung yieldingly inwardly toward each other about the pivots 30 to engage the sole and shoe by mechanism which is more fully disclosed in the Ballard et al. patent referred to.
- the right-hand end of the pad box is provided with vertical guideways 38 in which an end wall 40 carrying a horizontal outwardly extending bracket is mounted for sliding movement, the end wall 40 being maintained normally in an upward position by compression springs 42 engaging its bottom and bearing at their lower ends against a bracket 44 secured on the section l2 of the pad box.
- a threaded stem 46 (Fig. 3) fixed in the end wall 40 extends downwardly through the bracket 44 and has a nut 48 threaded on its below the bracket.
- the present construction is provided with a pair of sole-engaging fingers 50 (Fig. 2) adapted to engage the opposite edge faces of the heel portion of the sole and with a forked member 52 for engaging the opposite sides of the heel portion of the shoe, the sole-engaging fingers 50 being similar to those disclosed in the abovementioned Better patent.
- the end wall 40 has projecting horizontally toward the right from its inner and outer sides a pair of spaced and parallel studs 54.
- a pair of upwardly extending arms 56 On the studs 54 are pivotally mounted a pair of upwardly extending arms 56, connected together at their upper ends, by pivot studs 58 (Fig. 3) and a cross-bar 60.
- the left hand or outer arm 56 has a short lug" 62 extending inwardly from it which lies between spaced and adjustable screws 64 passing vertically through ears formed on the end wall 40, the screws 64 serving to limit the extent to which the arms 56 may rock about the studs 54.
- the arms 56 provide a parallel linkage arrangement which allows the cross bar 60 to remain horizontal as the arms swing about their studs and the cross bar is utilized to support the heel-end sole and shoe locating mechanisms.
- the central portion of the cross bar 60 is formed as a 'rod on which is freely pivoted a casting 88 which extends .from the cross bar towards the toe end of the pad box in a substantially horizontal plane.
- the eastingBIi rests on a roll 68 which is freely rotatable in ears extending upwardly from the upper end of a stem'18 slidable axially but held against rotation in, a vertical boreformed in a projection on the end wall '48.
- a screw I2 (Fig; 3) threaded into the lower end 'of said bore abuts against the lower end of the stem I8 and a spring (not shown) coupled to the casting I58 and end wall 48 serves to urge the stem I8 downwardly into constant engagement with the screw.
- the casting 66 may be raised or lowered about the cross bar 68 to .cause the sole-locating fingers supported thereby to occupy a proper position relatively to the upper face of the pad 38 in the pad box.
- a tension spring 88 connected to the pin 82 tends constantly to urge the pin toward the left, as viewed in Fig. 2, and therefore to swing the arms I6 and the sole-engaging fingers carried thereby inwardly toward each other.
- a sliding bar 88 having a relatively wide head 88 on its right-hand end, is arranged to be moved towards the right in a substantially horizontal path when the sole-engaging fingers 58 are to be moved apart to. allowa sole to be placed between them on the pad, the head 88 then abutting against a roll 98 onthe pin 82 and thereby rocking the forwardly extending portions of the arms I6 apart.
- lever 96 At its lower end the lever 96 is connected by a rod I88 '(Fig. l) with the upper end of a lever.
- the casting 88 has formed in its inner and outer. portions, horizontal bores which extend lengthwise of the pad box.
- a rod I84 (Fig.3) on the projecting, opposite ends of which is freely mounted an upstanding bracket I88 having its sides spaced apart to embrace anv adjacent portion of the casting 86.
- a rod I88 (see also Figs. 1 and 2) extending lengthwise of the pad box is secured, by means of set screws I I8, in the side portions of the bracket I86 and the left-hand portion of the rod I88 extends toward the toe end of the pad box for a considerable distance beyond the bracket.
- a rod H2 is secured in the outer bore in the casting 66 (Fig. 3) and on the left-hand end of this rod, as viewed in Fig. 2, is freely mounted a link I I 4 of the same length, considered heightwise of the pad box, as the bracket I88.
- a rod II6 extends, parallel to the rod I88, through a bore in the upper end of the link I I8 and the opposite ends of the rod IIB are secured, at opposite sides of the link- H8, in ears II8 formed on the outer side of a frame I28 carrying the fork member 52.
- the frame I28 is providedat its inner portion with a second pair of ears I22 (Fig. 2) lying in line with the outer ears I I8 and the ears I22 have a sliding fit on the rod I88.
- a tension spring I24 connected to the frame I28 and to the lefthand end of the rod I88 tends to urge the frame I28 toward the toe end of the pad, the frame sliding along the rod I88 'and the outer rod II6 sliding through the link H8
- the rod- I88 may conveniently have a number of holes I26 (Fig.
- the heel fork 52 may be retained in an inoperative position when it is not to be used as, for example, when it is desired tolocate the heel ends of a sole and a shoe having a so-called wedge heel by utilizing only the sole locating fingers 58 in the manner hereinafter to be described.
- the heel positioning fork carried by the frame I28 is provided by a pair of shoe engaging plates I28 about one inch in height and an inch and three quarters in length, these plates being pivotally secured near. their right-hand ends to slide members I38 by vertical clamping bolts I32, (Fig. 2). By slackening the bolts I32, the left-hand ends of the plates I28 can be swung toward or away from each other to allow the relatively narrow heel portions of small shoes and the relatively wide heel portions of large shoes to project substantially equal distances between the plates.
- each slide member having a' pair of vertical holes I34 formed in its upper face and spaced apart, conveniently one inch, along the slide member.
- Ver-- The slide members I38 are mounted in parallel guideways formed in the frame I28 and 45 d1rect1on than 1s necessary when the machineis tically slidab-le pins I36, one for each slide member, mounted in holes in the frame I are arranged to enter one of the holes I34 in each slide member to hold the latter in fixed position, lengthwise of the pad box, on the frame member 120.
- the slide members I can be slid toewardly or heelwardly on the frame until the pins come into alignment with the other holes, thus facilitating the appropriate positioning of the plates I28 for engaging the heel ends of shoes which vary considerably in length.
- the bracket I06 has a downwardly extending arm I38 (Fig. 3), to which is secured, by a pivot pin M0 extending lengthwise of the pad box, a tubular socket I42 in which is threaded the inner end of a rod I 44, (indicated only in Figs. 1 and 3), the outer end of which is threaded into a block I46 (Fig. 3) pivotally secured on the casting 66.
- the opposite ends of the rod I44 are provided with left and right-hand threads and by rotating the rod by means of a hand nut I48 on its outer end the bracket I06 can be rocked about its supporting rod I04, the link I I4 moving meanwhile about the rod I I2 to cause the frame I 20 to move widthwise of the pad box.
- the sole locating fingers 50 for positioning the heel end of the sole may also be conveniently arranged to engage the heel portion of a short sole that is, a sole for a childs shoe, in a position along the sole corresponding to that in which they engage a large sole so that the fingers may more readily position the heel end portions of different soles accurately on the pad,
- the illustrative embodiment is provided with means whereby the sole locating fingers may be adjusted lengthwise of the pad relatively to their actuating arms I6.
- each finger 50 comprises a fiat-bar I50 resting on the upper face of the casting '66 and underlying an extension I52 (Fig. 2) projecting toward the toe end of the pad box from its arm I6.
- the right-hand end portions of the bars I50 have slots I54 formed therein into which extend pins I56 depending from the arms 16.
- the extensions I52 have'secured to the under sides of their left-hand or toeward ends, depending lugs I58 which are cut away on their inner sides to provide horizontal grooves which the outer sides of the bars I50 comprising the fingers enter, leaf springs I60 fixed to the extensions I52 being provided to bear against the inner edges of the.
- bars I 50 may each conveniently have cut in their outer edges a notch I62 of a width corresponding to the width of the grooved lug I58, these notches being positioned near the left-hand ends of the bars.
- the bars I50 each have another notch I64 cut in their outer edges, these second notches being spaced from the shoe engaging ends of the bars about two inches further than the notches I62.
- the shoe engaging ends of the bars will occupy positions some two inches near the toe end of the pad than they previously occupied and will actually overlie the heel portion of the pad in a position suitable for engaging the opposite sides of the heel end portion of a'short sole for a small size shoe on the pad.
- the said support is arranged to be readily -m,ovable lengthwise of the pad box, when it is desired to use the sole positioning fingers 50 instead of the pin, to a position where the pin I66 is retracted from operative position over the pad anddoe's not interfere with the operation of the sole locating fingers on the heel end of a sole which has no locating hole in it.
- a small bifurcated bracket H2 is rotatably and slidably mounted on the rod I10 and this bracket has secured to it an inwardly extending arm I"I4 which has a downwardlyextend- -ing face at the left-hand side of its inner end, as viewed in Fig. 2, to which is secured a resilient tongue I16 extending lengthwise of the .pad box Ell) and arranged to extend more or less centrally between the shoe engaging plates I28 on 'the heel positioning fork but lying at a somewhat lower level than these plates so as just to overlie the upper surface of the'pad.
- the tongue I16 carries the depending pin I66 and when the bracket I12 occupies its 'most toeward or left-hand position along the rod I'III (which position it occupies when the pin Ifiiiiis in operative position) the pin may occupy a position normally some inch and a half toewardly of the heel end of the pad in the pad box, this position adapting it generally for operating on the varying sizes of soles for womens shoes;
- the bracket I I2 may be swung outwardly toward the operator about the rod I'IU by means of a handle IIB secured thereon to lift the tongue I15 and pin I65 above other partswhich' are located at their right and the bracket and tongue may then be slid rearwardly of the pad box toward the right to move the pin I66 into a position,
- a latch I80 (shown only in Figs. 2 and 3) pivoted on'a stud I82 secured in the casting 66.
- the latch I80 may be swung from the position inwhich it is shown in Fig.2 up wardly and towards the left through 180 until its 'end face I84 engages the right-hand edge face of one of the arms I6 when thelatter have been forced apart against the action of the spring 84 by the operator.
- the latch IBIIthus forms a stop preventing return movement of the arms I6 abouttheir pivot pins 14'.
- the tongue I16 is urged into contact'with the surface of the pad by a torsion spring I86 (Fig. 1)' mounted on thehubof a depending arm I88 free- 1y mounted on the rod I10 and" embraced by bifurcated portions of the bracket H2.
- the arm I 853 has secured in its lower end a stud I90 on which is rotatably mounted a roll I92.
- the arrangement is such that one end of the torsion spring I86 abuts against the bifurcated bracket I12 and urges the tongueI'IIi downwardly intocontact with the pad.
- the other end of” the spring I8 6 acts uponthe depending arm I88 and serves to hold the roll I92 in contact with a rod I9 carried by the casting 66 and lying parallel to the rod I'M).
- bracket I12 When, as hereinbefore stated, it is desired to remove the sole engaging pin from operative position the bracket I12 may be swung outwardly and upwardly by its handle I'IB against the action of the spring I 36 and then moved toward the right, as described above, the roll I92 being caused thereby to track along the rod I94 during the movement of the pin away from the heel-end of the pad.
- the heel positioning fork, the sole locating fingers 50 and the pin I66 are all carried by the casting 66 which, during the time in which the operator is positioning a sole andxshoe on the I pad, is free to move somewhat widthwise of the pad.
- the shoe engaging fork 52 has capacity for widthwise adjustment in relation to the sole locating fingers and sole locating pin.
- the operator will first place the sole (which may for the moment be assumed to be a sole for a womans shoe having a hole in its heel portion) on the pad with the tongue IIB overlying its heel portion and the sole locating pin I66 in engagement with the hole in the sole.
- latch I80 will be held inoperative by the latch I80 aforementioned and they may, as an extra precaution, be slid toward the right, as viewed in Fig. 2, along their arms I6 into a position away from over the pad, the notches I62 then engaging with the lugs I58.
- the operator may then depress a treadle of the machine which, through mechanism hereinafter referred to, will first release the forepart shoe and sole locating fingers and the sole-locating fingers for the heel portion of the sole from the open position to which they will previously have been moved. Continued depression of the treadle allows the forepart sole and shoe locating fingers to close, causing the sole fingers to engage the edges of the sole. The sole is now held positioned on the pad by the two fingers 2i!
- the heel'locating pin I66 and the operator may, if necessary, adjust the heel positioning fork 52, widthwise of the pad box, relatively to the heel locating pin I66 by rotation of the rod IM so that the heel end of the shoe will, when it is placed on the sole, be positioned in the desired transverse relation to the heel end of the sole.
- the sole and shoe locating mechanisms for the heel portions of the sole and shoe are able to move freely widthwise of the pad enables this disadvantage to be overcome in the following manner.
- the operator In placing the shoe on the possibly distorted sole positioned on the pad, the operator first places the heel end of the shoe into the shoe engaging fork 52. He then moves the shoe andthe fork rearwardly or toward the right, as viewed in Figs. 1 and 2, until he is able to lower the forepart of the shoe between the forepart shoe gages 22. The shoe now becomes positioned both at its heel and toe ends and the operator may hold it thus without actually lowering it into contact with the sole.
- the operator By looking downward toward the pad directly from above the shoe, the operator will readily be able to see whether the sole has been distorted in positioning it on the pad by observing whether the outlines of the shoe and sole are in conformity at their shank portions. If he finds that the sole projects further than is desired beyond one side of the shank of the shoe he may easily move the heel ends "of the shoe and sole in the proper direction widthwise of the pad box, that is, either outwardly or inwardly of the pad In such a case box and may thus straighten the shank portion of the sole while maintaining the shoe and sole correctly positioned at their forepart and heel portions, the fork 52 and sole positioning means retaining their relative positions undisturbed during such movement.
- the operator may thereafter lower the shoe still further until it actually contacts with the sole and then swing outwardly over the shoe the shoe engaging abutments I 96 (Fig. 1) with which the machine is provided and which are later caused automatically to descend to press the shoe and sole together against the pad.
- the heel end locating mechanisms for the sole and shoe should be locked against further movement widthwise of the pad box and the present construction includes means which acts automatically to lock the casting 66 against further widthwise movement when the abutments I96 are swung outwardly into operative position over the shoe.
- one of the uprights of the swinging frame member disclosed in the Ballard et al. patent which carries the pressure applying abutments I96 has a pin I98 (Fig. 3) secured in it which enters a slot 200 formed in a link 202 which is connected at its outer end by a pin 263 to the upper end of a pivoted locking lever 264.
- the lever 264 is secured at its lower'end on a pin 266 which is freely rotatable in the bracket 44 and fixed to this pin is a short upstanding arm 268.
- the arm 208 carries a lockingroll 2H1 on which rests a block 2I2 lying between a face on the upper end of the arm 208 and an adjacent face on the bracket 44 and held against movement outwardly and inwardly of the pad by pins 2M contacting with its outer and inner sides.
- the casting 66 has a lug 2I6 extending inwardly from it through which passes a pin 2I8 extending into a vertical slot 220 formed in the forward end of a slide 222.
- This slide has also a horizontal slot 224 formed in it in which are located rolls 226'freely rotatable on pins supported in the bracket 44, these rolls normally engaging the upper edge of the slot 224 to support the slide 222.
- the slot 224 is wider than the diameter of the rolls 226 and the slide therefore has some freedom to rise relatively to the rolls.
- the upper edge of the slide 222 is V-shaped in cross section and is received within a similarly shaped groove formed along the under face of a plate 228 secured to the bracket 44.
- the slide 222 moves outwardly or inwardly with them.
- the pin I98 strikes the forward end of the slot 200 in the link 202', as shown in Fig. 3, and thus swings the locking roll 208 up wardly to the position shown in Fig. 3 to force the block 2 I2 upwardly and thus to clamp the slide 222 against the underface of the plate 228, thus locking the heel locating mechanisms against further movement widthwise of the pad box.
- the pin I98 strikes against the rear end of the slot 200 and releases the heel end 10- cating members.
- the pad box may be desired to utilize the pad box to attach relatively thin soles to shoes having a socalled wedge heel, that is, a low heel consisting of but a few heel lifts already attached to the shoe.
- a pad which is thinner or shallower at its heel end portion than at the shank portion to accommodate the extra thickness provided by the heel. Since the wedge heel will already be permanently attached to the shoe and since the sole will, usually at least, be relatively thin, the sole engaging fingers 50 may be used alone to position the sole and shoe relatively to each other upon the pad by engagement of the lowermost portions of the fingers with the edge of the sole, and by engagement of the upper portions of the fingers with the edge face of the wedge heel.
- the heel engaging fork 52 should be urged well over toward the right or rear end of thepad box and should be prevented from moving again toward the left by inserting the stop pin aforementioned in an appropriate one of the holes I26 which will then be positioned at the left of the right-hand ear I22.
- the sole locating pin I66 which of course will not then be used, should also be moved toward the right away from over the pad into its inoperative position.
- the locating means for the forepart and heel portions of the sole are arranged to be withdrawn automatically from operative position to their opened positions when the turret of the machine has substantially completed a revolution and the pressing operation on a shoe has been substantially completed.
- a machine of the type disclosed in the Ballard et al. patent may be provided with an arrangement such as is indicated in Fig. 4.
- a downwardly extending part of the turret of the machine is indicated at 230 and the turret carries a plurality of bell crank levers (one associated with each pad box on the turret) as disclosed in the Ballard et al. patent, the upright arms of these levers providing the gage actuating levers I 02 previously referred to and indicated in Fig. l.
- viewed in Fig. 1 allows the sole engaging fingers 2H and at the toe and heel ends of the pad to be swung inwardly by their respective springs into engagement with the sole.
- the roll 234 is not directly supported upon the lever 236 but is supported just out of contact with the latter by a pivoted latch 238 having a hooked lower end 2 42 which underlies a projection 242 on the arm 232.
- the latch 238 is normally urged in a direction to maintain its hooked end beneath the projection 242 by a spring 254 coupled to an outwardly projecting finger 246 on the latch, a pin 248 fixed in the turret serving by contact with an inwardly extending finger 250 on the latch to limit its movement in that direction.
- a rod 252 connected to the treadle is connected to a block 25 1 which has pivoted on it at 255 a pawl 256 having a hooked upper end whicliis normally caused to overlie the outer end of the finger 246 by a torsion spring 258 surrounding the pivot 255.
- the lower end of the pawl is beveled downwardly and inwardly as indicated at 280 and lies directly above and is spaced from a fixed pin 262. Descent of the treadle rod 252 therefore, will swing the latch 238 in a direction to move its hooked end away from beneath the projection 2-22, thus allowing the roll 234 to descend upon the lever 236.
- the lever 236 In order to lower. the lever 236, after the roll 23% has descended upon it and thereby to allow the fingers 2E] and 59 to swing inwardly into engagement with the edge of a sole on the pad, the lever has pinned to it a downwardly extending rod 262-.
- This rod has secured on it, below the block 254, an abutment 266 against which the block 252 strikes after the pawl 25% has been swung away from over the finger 2 16 so that, during depression of the treadle, the roll 23a is first released to descend upon the lever 236 and the latter is then drawn downwardly to allow the fingers 2i] and 5G to engage the sole edge.
- a plunger the outer end of which is indicated at 212 in Fig. 4 and which bears against the inner end of an adjustable screw 2M threaded in the lower end of a lever 2'56 pivoted at 2% on the bracket Eli
- a spring 2% serves to maintain the screw in contact with the plunger.
- a rounded face 282 formed on the lever 2% near its upper end is arranged to underlie a face 28 formed on the arm 232 of the bell crank lever controlling the fingers 2t and 5a and the face 286 is arranged to come into contact with the face 232 when the arm 232 has been allowed to descend, by the descent of the lever 236, to cause the fingers 20 and to close upon the sole.
- the plunger 212 will be advanced under hydraulic pressure and the lever 2% will be rocked about its pivot 218 in a direction to raise the arm 232 and thereby to pull the fingers 20 and 50 away from engagement with the work.

This invention relates to improvements in machines for applying pressure to shoe bottoms and is herein illustrated as embodied in a machine of the type disclosed in Letters Patent of the United States No. 2,047,185, granted July 14, 1936', in the name of Milton 1-1. Ballard et al.
As disclosed in the patent referred to, the machine is provided with a rotary turret arranged to rotate in a horizontal plane and carrying a plurality of pad boxes mounted on the turret with their longer axes extending in the direction of its rotation. The pad boxes are provided with shoe receiving pads and each pad box has associated with it a set of sole and shoe positioning mechanism for relatively positioning soles and shoes placed on its pad.
The particular means on each pad box for relatively locating the heel ends of a sole and shoe mounted on the pad comprises a sole locating pin adapted to enter a hole in the center of the heel portion of the sole, a heel fork member having diverging faces for engaging the opposite sides of the heel end of the shoe, and mechanism for moving the pin, while engaging the sole, laterally of the shoe to move the sole into the desired position relatively to the heel end of the shoe.
This sole, and shoe positioning mechanism is particularly arranged for operating on womens shoes in which the heel portions of the soles are usually of a relatively thin and flimsy construction which does not permit the soles to be easily positioned relatively to the shoeby members such as gage fingers adapted to engage the opposite edge portions of the soles.
In order to adapt thepad boxes for operating on mens shoes in which the soles are relatively thick and the heel portions of which have no hole therein for receiving the sole locating pin above referred to, the pad boxes have been redesigned in the manner disclosed in Letters Patent of the United States No. 2,005,755, granted June 25, 1935 on an application filed in the name of Francis J. Better and in Letters Patent of the United States No. 2,063,041, granted December 8, 1936 in the name of Floyd G. Knowles. As disclosed in the two last-named patents, the sole and shoe positioning mechanism for operating on the heel ends of mens shoes comprises a pair of sole locating gages or fingers for engaging the opposite edges of the heel end of a mans relatively thick sole and a similar pair of gages or fingers for engaging the opposite sides of a mans shoe, these gages being held against movement away from the sole and shoe after they have contacted therewith and operating to move the sole and shoe relatively to each other and thus to bring their heel end portions into proper alinernent with each other.
It will be apparent from the foregoing that neither the sole and shoe locating mechanism of the pad box disclosed in the Ballard et al. patent nor that disclosed in the Better and the Knowles patents is adapted for operating with equal facility on both mens and womens shoes, and accordingly it has been necessary heretofore to provide alternative pad boxes carrying different gage mechanisms when both mens and womens shoes are to be operated upon.
An object of the present invention is to provide for use in a machine of the type referred to a pad box having sole and shoe positioning mechanism mounted thereon that will operate efiicient ly and with substantially equal facility on shoes that vary widely in size and style, for example, on womens shoes having relatively flimsy soles with sole locating holes in their heel portions, and also on mens shoes having relatively thick soles with no holes in their heel portions. Another object of the invention is to provide an improved arrangement which will eliminate the possibility of a thin flimsy sole being cemented to a shoe in a twisted or otherwise distorted condition. A further object of the invention'is to provide improved means for withdrawing from operative position those sole and shoe positioning members or gages which might tend to injure either the sole or the shoe by remaining in engagement therewith as the sole and shoe are forced against the pad by pressure exerted on the shoe by the machine. 1
With these objects in view an illustrative embodiment of the invention comprises a pad box containing a pad and having forepart positioning mechanism similar to that disclosed in the Ballard et a1. patent referred to, except that only one pair of forepart gages is utilized in the present construction. Heel end locating or gaging means for a shoe is provided similar in some respects to that disclosed in the said Ballard et al. patent and similar in other respects to that disclosed in the Better patent above referred to. The heel end sole locating gages or fingers in the present construction, however, are, in accordance with one feature of the invention, capable of being slid, relatively to their actuating mechanism, lengthwise of the pad box to enable them to engage both large and small soles and the heel end locating means for the shoe is also capable of sliding lengthwise of the pad box to enable it to operate easily on shoes of varying sizes.
The illustrated pad box, moreover, in accordance with another feature of the invention, is provided with pivotally mounted supporting means for a pin for engaging a hole in the heel end of a sole for a womans shoe and this pin is arranged to be readily movable out of operative position when it is desired to position a sole for a mans or a childs shoe on the pad, which sole has no locating hole in its heel portion and which, accordingly, is located with the aid of sole locating gages or fingers. The illustrated arrangement is such that when the sole locating pin is in a position for operating on a sole for a womans shoe it, and the heel portion of the sole which it engages, will occupy such a position lengthwise of the pad that they will be spaced from the locating fingers for operating on mens soles so that the fingers will not be in a position to foul the pin or the sole even though they are actuated idly by their actuating mechanism when the pin is in use. Moreover, the heel end locating mechanism for the shoe and the sole locating pin and the gage fingers are all mounted in such a manner as to allow them to be moved as a unit widthwise of the pad after they have positioned the heel ends of the shoe and sole thereon, thereby enabling the operator to straighten the sole, if necessary, or to remove from its shank portion any wrinkles or creases which may have been formed therein owing to the sole having been initially placed on the pad in a somewhat twisted condition.
A further featureiof the invention resides in the provision of means for automatically withdrawing from operative position and looking or latching in their withdrawn position any sole and shoe gages or fingers which, by their engagement with the sole or shoe during the pressure applying operation, might tend to injure the latter as they are pressed against the pad. As illustrated herein the gage withdrawing means is fluid pressure controlled by the hydraulic mechanism of the machine disclosed in the Ballard et al. patent for applying pressure to the sole and shoe and the arrangement is such that the withdrawal and latching of the gages is not 'efiected until after sufficient pressure has been applied to the sole and shoe to insure that they will not become displaced relatively to each other by further pressure applied after the gages are withdrawn.
With the above and other objects and features in View the invention will now be described in connection with the accompanying drawings and will thereafter be pointed out in the claims.
In the drawings,
Fig. 1 is a front elevation of a pad box embodying the present invention;
Fig. 2 is a plan View of the pad box;
Fig. 3 is a right-hand end View of the pad box on a larger scale and the shoe and sole heel locating means associated therewith; and
Fig. 4 is .a side elevation of mechanism for withdrawing certain of the shoe and sole locating means from operative position prior to the application of the full pressure on the sole and shoe.
The pad box illustrated herein is similar, in certain respects, to that disclosed in the Ballard et al. patent aforementioned and comprises left and right-hand portions or sections In and I 2 pivoted together about an axis I4 located substantially at the mid-portion of the pad box. Means including an arcuate notched block [6 and a co-operating and withdrawable latch-bolt l8 are provided for retaining the forepart section ID of the pad box in any desired angular position into which it may be adjusted about the axis M. The section IU of the pad box carries forepart gaging mechanism including a pair of sole locating fingers (Fig. 2) and shoe locating fingers 22 carried by arms 24 similar to those referred to in the Ballard et al. patent, these arms being pivoted for free vertical movement on pivots 26 carried by members 28 (Fig. 2) which in turn are pivoted at 30 on the section In. The fingers 20 and 22 are supported by blocks formed on stems 32 which are adjustably clamped in the arms 24 by bolts 34 passing through split portions of the arms. The fingers 20 and 22 are adjustable lengthwise of the arms 24 by movement of the stems 32 in the arms to vary their positions for operating on shoes which differ appreciably in length, thereby permitting the fingers to engage the opposite sides of a shoe and a shoe on a pad 36 in the pad box at the desired position, which is preferably at, or a little toeward of, the tip line of the shoe. These fingers are arranged to be swung yieldingly inwardly toward each other about the pivots 30 to engage the sole and shoe by mechanism which is more fully disclosed in the Ballard et al. patent referred to.
The right-hand end of the pad box, as viewed in Fig. 1, is provided with vertical guideways 38 in which an end wall 40 carrying a horizontal outwardly extending bracket is mounted for sliding movement, the end wall 40 being maintained normally in an upward position by compression springs 42 engaging its bottom and bearing at their lower ends against a bracket 44 secured on the section l2 of the pad box. A threaded stem 46 (Fig. 3) fixed in the end wall 40 extends downwardly through the bracket 44 and has a nut 48 threaded on its below the bracket. By adjusting the nut 48 the heightwise position of the wall 40 and parts carried thereby may be varied as may be necessary for operating on shoes of different shapes and sizes.
For relatively positioning the heel portions of shoes such as mens or childrens shoes the soles of which have no locating holes in the center of their heel portions, the present construction is provided with a pair of sole-engaging fingers 50 (Fig. 2) adapted to engage the opposite edge faces of the heel portion of the sole and with a forked member 52 for engaging the opposite sides of the heel portion of the shoe, the sole-engaging fingers 50 being similar to those disclosed in the abovementioned Better patent. For supporting the sole-engaging fingers 50 and the shoe-engaging fork 52, the end wall 40 has projecting horizontally toward the right from its inner and outer sides a pair of spaced and parallel studs 54. On the studs 54 are pivotally mounted a pair of upwardly extending arms 56, connected together at their upper ends, by pivot studs 58 (Fig. 3) and a cross-bar 60. The left hand or outer arm 56 has a short lug" 62 extending inwardly from it which lies between spaced and adjustable screws 64 passing vertically through ears formed on the end wall 40, the screws 64 serving to limit the extent to which the arms 56 may rock about the studs 54.
It will be understood that the arms 56 provide a parallel linkage arrangement which allows the cross bar 60 to remain horizontal as the arms swing about their studs and the cross bar is utilized to support the heel-end sole and shoe locating mechanisms. For this purpose the central portion of the cross bar 60 is formed as a 'rod on which is freely pivoted a casting 88 which extends .from the cross bar towards the toe end of the pad box in a substantially horizontal plane. Toewardly of the cross bar the eastingBIi rests on a roll 68 which is freely rotatable in ears extending upwardly from the upper end of a stem'18 slidable axially but held against rotation in, a vertical boreformed in a projection on the end wall '48. A screw I2 (Fig; 3) threaded into the lower end 'of said bore abuts against the lower end of the stem I8 and a spring (not shown) coupled to the casting I58 and end wall 48 serves to urge the stem I8 downwardly into constant engagement with the screw. By rotating the screw. I2 the casting 66 may be raised or lowered about the cross bar 68 to .cause the sole-locating fingers supported thereby to occupy a proper position relatively to the upper face of the pad 38 in the pad box.
.of this extension. A tension spring 88 connected to the pin 82 tends constantly to urge the pin toward the left, as viewed in Fig. 2, and therefore to swing the arms I6 and the sole-engaging fingers carried thereby inwardly toward each other. A sliding bar 88, having a relatively wide head 88 on its right-hand end, is arranged to be moved towards the right in a substantially horizontal path when the sole-engaging fingers 58 are to be moved apart to. allowa sole to be placed between them on the pad, the head 88 then abutting against a roll 98 onthe pin 82 and thereby rocking the forwardly extending portions of the arms I6 apart.
In order to movethe bar 86 toward the right, as
viewed in Figs. 1 and 2, in the desired manner and at the proper time, its left-hand portion has a slot 82 which receives a relatively fixed guiding roll 98 while its right-hand end portion is pivotally connected to the upper end of a lever 96 (see also Fig. 3) which is freely mounted between its ends on a fixed pivot pin 88 secured in the bracket 44.
At its lower end the lever 96 is connected by a rod I88 '(Fig. l) with the upper end of a lever.
I82, corresponding to the lever in the Ballard et al. patent which is actuated by a treadle to operate the forepart positioning gages, which lever is arranged to be rocked automatically, in a counter-clockwise direction, as seen from the. front of the machine, when the turret has rotated far enough to cause the pad box under consideration once more to approach the operating station.
When the lever I82 is rocked in a counterclock- 'wise direction it not only separates-the forepart positioning fingers, through mechanism described in the patent last referred to, but also moves the bar 88 towards the right and separates the gage fingers 58 carriedby the arms It, as more fully explained hereinafter.
The casting 88 has formed in its inner and outer. portions, horizontal bores which extend lengthwise of the pad box. In the inner bore is secured a rod I84 (Fig.3) on the projecting, opposite ends of which is freely mounted an upstanding bracket I88 having its sides spaced apart to embrace anv adjacent portion of the casting 86. A rod I88 (see also Figs. 1 and 2) extending lengthwise of the pad box is secured, by means of set screws I I8, in the side portions of the bracket I86 and the left-hand portion of the rod I88 extends toward the toe end of the pad box for a considerable distance beyond the bracket.
A rod H2 is secured in the outer bore in the casting 66 (Fig. 3) and on the left-hand end of this rod, as viewed in Fig. 2, is freely mounted a link I I 4 of the same length, considered heightwise of the pad box, as the bracket I88. A rod II6 extends, parallel to the rod I88, through a bore in the upper end of the link I I8 and the opposite ends of the rod IIB are secured, at opposite sides of the link- H8, in ears II8 formed on the outer side of a frame I28 carrying the fork member 52. The frame I28 is providedat its inner portion with a second pair of ears I22 (Fig. 2) lying in line with the outer ears I I8 and the ears I22 have a sliding fit on the rod I88. A tension spring I24 connected to the frame I28 and to the lefthand end of the rod I88 tends to urge the frame I28 toward the toe end of the pad, the frame sliding along the rod I88 'and the outer rod II6 sliding through the link H8.
The fact that the frame I28 is thus slidable, through a substantial distance, lengthwise of the pad box and is normally urged toward the toe end of the pad box by a spring, enables the shoe engaging fork 52 which it carries to engage effectively the opposite sides of the heel portions of shoes which vary greatly in size'and the forepart portions of which are positioned between the fingers 22, it being understood that these latter fingers may be adjusted on the arms 24 toward the heel end of the pad box to enable them more effectively to engage shoes, such as childrens shoes, which are relatively short. The rod- I88 may conveniently have a number of holes I26 (Fig. 2) spaced apart along the upper face of its right-hand portion into any of which a stop pin may be inserted to limit the movement of the frame I28 toward the right, thus preventing the operator from urging the frame further in that hand ear I22 on the frame,'the heel fork 52 may be retained in an inoperative position when it is not to be used as, for example, when it is desired tolocate the heel ends of a sole and a shoe having a so-called wedge heel by utilizing only the sole locating fingers 58 in the manner hereinafter to be described.
The heel positioning fork carried by the frame I28 is provided by a pair of shoe engaging plates I28 about one inch in height and an inch and three quarters in length, these plates being pivotally secured near. their right-hand ends to slide members I38 by vertical clamping bolts I32, (Fig. 2). By slackening the bolts I32, the left-hand ends of the plates I28 can be swung toward or away from each other to allow the relatively narrow heel portions of small shoes and the relatively wide heel portions of large shoes to project substantially equal distances between the plates.
extending toward the toe end of the pad box, each slide member having a' pair of vertical holes I34 formed in its upper face and spaced apart, conveniently one inch, along the slide member. Ver-- The slide members I38 are mounted in parallel guideways formed in the frame I28 and 45 d1rect1on than 1s necessary when the machineis tically slidab-le pins I36, one for each slide member, mounted in holes in the frame I are arranged to enter one of the holes I34 in each slide member to hold the latter in fixed position, lengthwise of the pad box, on the frame member 120. .By lifting the pins I36 out of theholes I34 which they engage at any time, the slide members I can be slid toewardly or heelwardly on the frame until the pins come into alignment with the other holes, thus facilitating the appropriate positioning of the plates I28 for engaging the heel ends of shoes which vary considerably in length.
The plates I28 normally occupy such positions widthwise of the pad box, when viewed from above, that the heel end portion of a shoe engaged thereby will lie centrally over the heel portion of a sole positioned between the fingers but, in order to enable the plates I28 tobe adjusted widthwise of the pad box relatively to the fingers 50, the bracket I06 has a downwardly extending arm I38 (Fig. 3), to which is secured, by a pivot pin M0 extending lengthwise of the pad box, a tubular socket I42 in which is threaded the inner end of a rod I 44, (indicated only in Figs. 1 and 3), the outer end of which is threaded into a block I46 (Fig. 3) pivotally secured on the casting 66. The opposite ends of the rod I44 are provided with left and right-hand threads and by rotating the rod by means of a hand nut I48 on its outer end the bracket I06 can be rocked about its supporting rod I04, the link I I4 moving meanwhile about the rod I I2 to cause the frame I 20 to move widthwise of the pad box.
In order that the sole locating fingers 50 for positioning the heel end of the sole may also be conveniently arranged to engage the heel portion of a short sole that is, a sole for a childs shoe, in a position along the sole corresponding to that in which they engage a large sole so that the fingers may more readily position the heel end portions of different soles accurately on the pad,
the illustrative embodiment is provided with means whereby the sole locating fingers may be adjusted lengthwise of the pad relatively to their actuating arms I6.
For this purpose the fingers 50 are formed separately from the arms I6 and are adjustable lengthwise of the pad box relatively to these arms. Each finger 50 comprises a fiat-bar I50 resting on the upper face of the casting '66 and underlying an extension I52 (Fig. 2) projecting toward the toe end of the pad box from its arm I6. The right-hand end portions of the bars I50 have slots I54 formed therein into which extend pins I56 depending from the arms 16. The extensions I52 have'secured to the under sides of their left-hand or toeward ends, depending lugs I58 which are cut away on their inner sides to provide horizontal grooves which the outer sides of the bars I50 comprising the fingers enter, leaf springs I60 fixed to the extensions I52 being provided to bear against the inner edges of the. bars to urge them into the grooves in said lugs. The pin and slot connections between the arms I6 and the righthand portions of the sole engaging fingers, and the engagement between the lugs on the toeward ends of the extensions I52 of said arms with the fingers constitute means whereby the arms and fingers are coupled positively together for equal and opposite swinging movement into sole-engaging position.
' Also by reason of the fact that the bars I50 carrying the sole engaging fingers are coupled to their arms I6 only by thepin and slot connection I54, I56 and the grooved lugs l58, the
fingers can readily be moved lengthwise of the pad box relatively to their arms, the slots in the bars tracking along the pins I56 and the bars sliding along the grooves in the lugs I58. The
bars I 50 may each conveniently have cut in their outer edges a notch I62 of a width corresponding to the width of the grooved lug I58, these notches being positioned near the left-hand ends of the bars.
When the bars are so adjusted lengthwise of the pad box that these notches I62 lie opposite the grooved lugs I68 the leaf springs I60 cause the notches to embrace the lugs and therefore to hold the bars against movement relatively to their arms I6 lengthwise of the pad box. These notches conveniently occupy such positions in the bars that when they embrace the lugs, the sole-engaging ends of the bars occupy positions spaced a short distance heelwardly away from the heel end of the pad so that they lie in convenient positions 'to engage the heel portion of a relatively large sole for a 'mans shoe.
The bars I50 each have another notch I64 cut in their outer edges, these second notches being spaced from the shoe engaging ends of the bars about two inches further than the notches I62. By swinging the shoe engaging ends of the bars inwardly toward each other relatively to their arms I6 and against the action of. their leaf springs I60, the notches I 62 may be withdrawn from their locking engagement with the grooved lugs I58and the bars can then be slid toward the toe end of the'pad, relatively to their actuating arms, a distance sufficient to bring the notches I64 in the bars in position to embrace the notched lugs I58 when the bars are released to the action of their leaf springs.
When this has been done the shoe engaging ends of the bars will occupy positions some two inches near the toe end of the pad than they previously occupied and will actually overlie the heel portion of the pad in a position suitable for engaging the opposite sides of the heel end portion of a'short sole for a small size shoe on the pad.
This is the position in which the bars are illustrated in Fig. 2.
To enable the pad box readily to operate effec tively on soles for womens shoes which have sole locating holes punched in the centers of, their heel portions it is provided with a pivoted and sliding support for a sole locating pin I66 which is arranged, when in operative position, to' enter into the locating hole in the heel portion of a sole and thereby to maintain that portion of the sole ina definite relation to a shoe engaged by the heel positioning fork.
The said support is arranged to be readily -m,ovable lengthwise of the pad box, when it is desired to use the sole positioning fingers 50 instead of the pin, to a position where the pin I66 is retracted from operative position over the pad anddoe's not interfere with the operation of the sole locating fingers on the heel end of a sole which has no locating hole in it.
box. A small bifurcated bracket H2 is rotatably and slidably mounted on the rod I10 and this bracket has secured to it an inwardly extending arm I"I4 which has a downwardlyextend- -ing face at the left-hand side of its inner end, as viewed in Fig. 2, to which is secured a resilient tongue I16 extending lengthwise of the .pad box Ell) and arranged to extend more or less centrally between the shoe engaging plates I28 on 'the heel positioning fork but lying at a somewhat lower level than these plates so as just to overlie the upper surface of the'pad. At its left-hand end the tongue I16 carries the depending pin I66 and when the bracket I12 occupies its 'most toeward or left-hand position along the rod I'III (which position it occupies when the pin Ifiiiiis in operative position) the pin may occupy a position normally some inch and a half toewardly of the heel end of the pad in the pad box, this position adapting it generally for operating on the varying sizes of soles for womens shoes;
When the sole-locating pin is not to be used, for example, when soles are to be positioned which have no locating holes in their heel portions, the bracket I I2 may be swung outwardly toward the operator about the rod I'IU by means of a handle IIB secured thereon to lift the tongue I15 and pin I65 above other partswhich' are located at their right and the bracket and tongue may then be slid rearwardly of the pad box toward the right to move the pin I66 into a position,
shown in Fig. 2, in which it is withdrawn from over the heel end of the pad'an'd in which it will not interfere with the operation of the sole locating fingers 50. When the sole locating pin is being utilized t position the heel end of a sole having a hole in its heel portion on the pad it is desirable that the sole engaging fingers 5!! be held in an open or inoperative position to give increased assurance that they will not interfere with the proper positioning of. the sole by. the pin. For this purpose there is provided a latch I80 (shown only in Figs. 2 and 3) pivoted on'a stud I82 secured in the casting 66. The latch I80 may be swung from the position inwhich it is shown in Fig.2 up wardly and towards the left through 180 until its 'end face I84 engages the right-hand edge face of one of the arms I6 when thelatter have been forced apart against the action of the spring 84 by the operator. The latch IBIIthus forms a stop preventing return movement of the arms I6 abouttheir pivot pins 14'.
The tongue I16 is urged into contact'with the surface of the pad by a torsion spring I86 (Fig. 1)' mounted on thehubof a depending arm I88 free- 1y mounted on the rod I10 and" embraced by bifurcated portions of the bracket H2. The arm I 853 has secured in its lower end a stud I90 on which is rotatably mounted a roll I92. The arrangement is such that one end of the torsion spring I86 abuts against the bifurcated bracket I12 and urges the tongueI'IIi downwardly intocontact with the pad. The other end of" the spring I8 6 acts uponthe depending arm I88 and serves to hold the roll I92 in contact with a rod I9 carried by the casting 66 and lying parallel to the rod I'M). When, as hereinbefore stated, it is desired to remove the sole engaging pin from operative position the bracket I12 may be swung outwardly and upwardly by its handle I'IB against the action of the spring I 36 and then moved toward the right, as described above, the roll I92 being caused thereby to track along the rod I94 during the movement of the pin away from the heel-end of the pad.
It will be realized from the foregoing description that the heel positioning fork, the sole locating fingers 50 and the pin I66 are all carried by the casting 66 which, during the time in which the operator is positioning a sole andxshoe on the I pad, is free to move somewhat widthwise of the pad. Also the shoe engaging fork 52 has capacity for widthwise adjustment in relation to the sole locating fingers and sole locating pin. In the use of'the pad box, therefore, the operator will first place the sole (which may for the moment be assumed to be a sole for a womans shoe having a hole in its heel portion) on the pad with the tongue IIB overlying its heel portion and the sole locating pin I66 in engagement with the hole in the sole. The sole engaging fingers 5!! will be held inoperative by the latch I80 aforementioned and they may, as an extra precaution, be slid toward the right, as viewed in Fig. 2, along their arms I6 into a position away from over the pad, the notches I62 then engaging with the lugs I58.
The operator may then depress a treadle of the machine which, through mechanism hereinafter referred to, will first release the forepart shoe and sole locating fingers and the sole-locating fingers for the heel portion of the sole from the open position to which they will previously have been moved. Continued depression of the treadle allows the forepart sole and shoe locating fingers to close, causing the sole fingers to engage the edges of the sole. The sole is now held positioned on the pad by the two fingers 2i! and the heel'locating pin I66 and the operator may, if necessary, adjust the heel positioning fork 52, widthwise of the pad box, relatively to the heel locating pin I66 by rotation of the rod IM so that the heel end of the shoe will, when it is placed on the sole, be positioned in the desired transverse relation to the heel end of the sole.
Owing to the fact that some'soles for womens shoes are relatively thin and flimsy in the shank portion it may be'difficult for the operator always to be certain, that'he has laid the sole in a fiat and undistorted condition on the pad and it may happen that the heel portion of the sole is positioned somewhat closer to the inner or outer side of the pad than it should be. the displacement of the heel portion of the sole from its .correct position might cause the shank portion of the sole to lie" out of alinement with the corresponding portion of the shoe when the latter is placed on the sole, this discrepancy gradually decreasing to a possibly negligible amount at the toe andheel ends of the shoe and sole.
The fact that, in the present construction, the sole and shoe locating mechanisms for the heel portions of the sole and shoe are able to move freely widthwise of the pad enables this disadvantage to be overcome in the following manner. In placing the shoe on the possibly distorted sole positioned on the pad, the operator first places the heel end of the shoe into the shoe engaging fork 52. He then moves the shoe andthe fork rearwardly or toward the right, as viewed in Figs. 1 and 2, until he is able to lower the forepart of the shoe between the forepart shoe gages 22. The shoe now becomes positioned both at its heel and toe ends and the operator may hold it thus without actually lowering it into contact with the sole. By looking downward toward the pad directly from above the shoe, the operator will readily be able to see whether the sole has been distorted in positioning it on the pad by observing whether the outlines of the shoe and sole are in conformity at their shank portions. If he finds that the sole projects further than is desired beyond one side of the shank of the shoe he may easily move the heel ends "of the shoe and sole in the proper direction widthwise of the pad box, that is, either outwardly or inwardly of the pad In such a case box and may thus straighten the shank portion of the sole while maintaining the shoe and sole correctly positioned at their forepart and heel portions, the fork 52 and sole positioning means retaining their relative positions undisturbed during such movement. The operator may thereafter lower the shoe still further until it actually contacts with the sole and then swing outwardly over the shoe the shoe engaging abutments I 96 (Fig. 1) with which the machine is provided and which are later caused automatically to descend to press the shoe and sole together against the pad.
When the shoe and sole have been correctly positioned on the pad in the manner indicated above, it is desirable that the heel end locating mechanisms for the sole and shoe should be locked against further movement widthwise of the pad box and the present construction includes means which acts automatically to lock the casting 66 against further widthwise movement when the abutments I96 are swung outwardly into operative position over the shoe.
For this purpose one of the uprights of the swinging frame member disclosed in the Ballard et al. patent which carries the pressure applying abutments I96 has a pin I98 (Fig. 3) secured in it which enters a slot 200 formed in a link 202 which is connected at its outer end by a pin 263 to the upper end of a pivoted locking lever 264. The lever 264 is secured at its lower'end on a pin 266 which is freely rotatable in the bracket 44 and fixed to this pin is a short upstanding arm 268. The arm 208 carries a lockingroll 2H1 on which rests a block 2I2 lying between a face on the upper end of the arm 208 and an adjacent face on the bracket 44 and held against movement outwardly and inwardly of the pad by pins 2M contacting with its outer and inner sides. The casting 66 has a lug 2I6 extending inwardly from it through which passes a pin 2I8 extending into a vertical slot 220 formed in the forward end of a slide 222. This slide has also a horizontal slot 224 formed in it in which are located rolls 226'freely rotatable on pins supported in the bracket 44, these rolls normally engaging the upper edge of the slot 224 to support the slide 222. The slot 224 is wider than the diameter of the rolls 226 and the slide therefore has some freedom to rise relatively to the rolls. The upper edge of the slide 222 is V-shaped in cross section and is received within a similarly shaped groove formed along the under face of a plate 228 secured to the bracket 44.
As the heel locating mechanisms for the sole and shoe are moved widthwise of the pad box in the manner previously indicated, the slide 222 moves outwardly or inwardly with them. When, however, the abu-tments I96 are swung forwardly over the shoe, the pin I98 strikes the forward end of the slot 200 in the link 202', as shown in Fig. 3, and thus swings the locking roll 208 up wardly to the position shown in Fig. 3 to force the block 2 I2 upwardly and thus to clamp the slide 222 against the underface of the plate 228, thus locking the heel locating mechanisms against further movement widthwise of the pad box. On movement of the abutments I 96 inwardly or away from the operator at the conclusion of the pressing operation, the pin I98 strikes against the rear end of the slot 200 and releases the heel end 10- cating members.
It will be understood that the advantages above indicated which may be derived from the ability of the heel end locating members to move widthwise of. the pad box will prove equally beneficial whether the sole locating pin I66 or the sole engaging fingers -5i] arebeing used for positioning a sole relatively to a shoe, and that the procedure adopted in positioning a shoe upon a sole positioned with the aid of the fingers 56 is substantially the same as that followed in positioning a shoe upon asole positioned with'the aid of the pin I66.
It may be desired to utilize the pad box to attach relatively thin soles to shoes having a socalled wedge heel, that is, a low heel consisting of but a few heel lifts already attached to the shoe. In such cases it is preferable to utilize in the pad box a pad which is thinner or shallower at its heel end portion than at the shank portion to accommodate the extra thickness provided by the heel. Since the wedge heel will already be permanently attached to the shoe and since the sole will, usually at least, be relatively thin, the sole engaging fingers 50 may be used alone to position the sole and shoe relatively to each other upon the pad by engagement of the lowermost portions of the fingers with the edge of the sole, and by engagement of the upper portions of the fingers with the edge face of the wedge heel. In order to simplify the use of the fingers 5!] in this manner it is desirable that the heel engaging fork 52 should be urged well over toward the right or rear end of thepad box and should be prevented from moving again toward the left by inserting the stop pin aforementioned in an appropriate one of the holes I26 which will then be positioned at the left of the right-hand ear I22. The sole locating pin I66, which of course will not then be used, should also be moved toward the right away from over the pad into its inoperative position.
Having placed a pad of the appropriate shape in the pad box and having moved the heel positioning fork and sole locating pin into their inoperative positions, it will probably then be necessary to adjust the heightwise positions of the fingers 50 'by lowering the fingers toward the pad so that they will engage the edges of both the sole and heel'in the manner indicated. This may readily be accomplished by rotation of the nut 48 aforementioned. If it seems necessary the fingers 50 may also be tilted about the axis of the cross bar 60 by appropriate adjustment of the screw 12 (Fig. 3) so that they will lie substantially parallel to the sole engaging face of the relatively thin heel portion of the'pad.
In the constructions disclosed in the Ballard et al. and Better patents previously referred to, the locating means for the forepart and heel portions of the sole are arranged to be withdrawn automatically from operative position to their opened positions when the turret of the machine has substantially completed a revolution and the pressing operation on a shoe has been substantially completed.
It has been observed, however, that if the sole locating fingers 20 and 50 are allowed to remain pressing against the work when the shoe and sole are forced bodily downwardly against the pad at the commencement of the pressing operation, there may be a tendency for those fingers to mark the sides of the shoe upper when the shoe descends between them as it is forced against the pad. With a view to overcoming this disadvantage a machine of the type disclosed in the Ballard et al. patent may be provided with an arrangement such as is indicated in Fig. 4. In this figure a downwardly extending part of the turret of the machine is indicated at 230 and the turret carries a plurality of bell crank levers (one associated with each pad box on the turret) as disclosed in the Ballard et al. patent, the upright arms of these levers providing the gage actuating levers I 02 previously referred to and indicated in Fig. l.
The lower arm of one of these bell crank levers is indicated at 232 in Fig. 4 and carries a roll 234' which when the turret is stationary, overlies a ledge on a trea'dle operated lever 236. As will be movement of the lever I02 towards the right, as
viewed in Fig. 1, allows the sole engaging fingers 2H and at the toe and heel ends of the pad to be swung inwardly by their respective springs into engagement with the sole.
In the present arrangement, however, the roll 234 is not directly supported upon the lever 236 but is supported just out of contact with the latter by a pivoted latch 238 having a hooked lower end 2 42 which underlies a projection 242 on the arm 232. The latch 238 is normally urged in a direction to maintain its hooked end beneath the projection 242 by a spring 254 coupled to an outwardly projecting finger 246 on the latch, a pin 248 fixed in the turret serving by contact with an inwardly extending finger 250 on the latch to limit its movement in that direction.
The upper end of a rod 252 connected to the treadle is connected to a block 25 1 which has pivoted on it at 255 a pawl 256 having a hooked upper end whicliis normally caused to overlie the outer end of the finger 246 by a torsion spring 258 surrounding the pivot 255. The lower end of the pawl is beveled downwardly and inwardly as indicated at 280 and lies directly above and is spaced from a fixed pin 262. Descent of the treadle rod 252 therefore, will swing the latch 238 in a direction to move its hooked end away from beneath the projection 2-22, thus allowing the roll 234 to descend upon the lever 236. When the rod 252 has been depressed sufficiently to effect the above action, the lower beveled end of the pawl 25E strikes against the pin 262 and the pawl is swung outwardly about its pivot to withdraw its hooked upper end from engagement with the finger 2% so as not to obstruct the return movement of the latter to operative position under the influence of its spring 2% even though the treadle be maintained temporarily in lowered position.
In order to lower. the lever 236, after the roll 23% has descended upon it and thereby to allow the fingers 2E] and 59 to swing inwardly into engagement with the edge of a sole on the pad, the lever has pinned to it a downwardly extending rod 262-. This rod has secured on it, below the block 254, an abutment 266 against which the block 252 strikes after the pawl 25% has been swung away from over the finger 2 16 so that, during depression of the treadle, the roll 23a is first released to descend upon the lever 236 and the latter is then drawn downwardly to allow the fingers 2i] and 5G to engage the sole edge. After the sole has been correctly located upon the pad and a shoe has been positioned on the sole in the manner previously described, the operator swings forwardly over the shoe the abutments Hi6 .and then depresses another treadle with which the machine disclosed in the Ballard et al. patent is provided to operate the hydraulic mechanism of the machine and cause the shoe to be pressed forcibly against the pad.
In order to cause the fingers 20 and 50 to be withdrawn from operative engagement with the work shortly after the downward pressure on the shoe commences, there is connected to the hydraulic power pressure system of the machine a pipe 268 (Fig; 4) leading into a small horizontal chamber formed in a bracket 2M fixed on the machine frame near the loading station.
In the said chamber is housed a plunger the outer end of which is indicated at 212 in Fig. 4 and which bears against the inner end of an adjustable screw 2M threaded in the lower end of a lever 2'56 pivoted at 2% on the bracket Eli A spring 2% serves to maintain the screw in contact with the plunger. A rounded face 282 formed on the lever 2% near its upper end is arranged to underlie a face 28 formed on the arm 232 of the bell crank lever controlling the fingers 2t and 5a and the face 286 is arranged to come into contact with the face 232 when the arm 232 has been allowed to descend, by the descent of the lever 236, to cause the fingers 20 and to close upon the sole. When the operator depresses the treadle controlling the hydraulic pressure mechanism of the machine to cause downward pressure to be applied to the shoe after he has correctly positioned the latter upon the sole, pressure will be built up in the chamber housing the plunger 212 substantially simultaneously with the building up of the pressure which forces the shoe against the pad.
Therefore during an early stage in the downward movement of the shoe and sole against the pad, the plunger 212 will be advanced under hydraulic pressure and the lever 2% will be rocked about its pivot 218 in a direction to raise the arm 232 and thereby to pull the fingers 20 and 50 away from engagement with the work. When the arm 232 is raised in this manner, the hooked end 24.9 of the latch 238 snaps under the projection 2 32 on the arm 232 and maintains the latter in raised position and thereby maintains the fingers 20and Si in withdrawn positions throughout the rotation of the turrent and until the particular pad box under consideration returns once more to the operating position and the rod 252 is pulled downwardly, after the shoe and attached sole have been removed and a fresh sole has been placed on the pad. I
As disclosed in the Ballard et al. patent re' ferred to the pad box is deep enough to support both a water-filled shoe engaging pad and a pair of rubber blocks or pads forming a bed on which the water-filled pad rests, one of the rubber blocks preferably underlying the forepart portion of the water-filled pad and the other underlying the heel end portion of the pad.
It is desirable that different water-filled pads be used in the pad box to suit the various kinds of work to be operated upon, the difierent pads being conveniently of the same overall dimensions but having, for example, different lengthwise and transverse curvatures on their sole engaging faces to simulate more closely the contours of the bottoms of the different shoes such as those for men, Women or children.
In order to allow the pad in the pad box to be quickly removed and replaced by another pad which is more suitable for operating on a diiferent kind of shoe, the illustrative pad box is provided with means which, although acting normally to hold the pad firmly in position in the pad box, can readily be moved to such a position that the pad may be easily and quickly removed from the box.
For this purpose the pad box carries on the ing somewhat to those disclosed in the Knowles patent above referred to and spaced from each other by rolls 289 only two of which are shown in Fig, 2.
The lower plate 288 bears against the margin of the pad around the forepart to hold it firmly on its bed. Interposed between the two plates is a two-part mask plate 290, the two sections of which are pivoted to each other at 29L The mask plate is adjustable lengthwise and widthwise of the pad box between the plates 286, 288 by means of a handle 292 fixed on a shaft 294 pivoted in the section 10, which shaft has a pair of arms 296 (one of which actually provides the handle 292) connected to the mask plate by links 298. The arm providing the handle 292 carries a spring pressed plunger 300 (Fig. 1) which rides, as the handle is moved, over a toothed plate 302 secured on the section I and serves to retain the mask plate in any position to which it may be adjusted. In order that the rolls 289 will not interfere with the lengthwise adjustment of the mask plate the sections of the latter are provided with slots 293 (Fig. 2) which receive the rolls, the slots being inclined relatively to the longitudinal median line of the pad so that the two sections of the mask plate will be adjusted toward and from each other during their lengthwise adjustment as is more fully described in the Knowles patent.
In order to allow the plates 286, 288 and 290 to be moved away from over the pad to facilitate removal of the pad from the box, the plates 286 and 288 are pivotally mounted on a horizontal shaft 304, indicated only in Fig. 1, extending widthwise of the pad box at a position beyond the toe end of the pad and approximately on the same level as the sole engaging face of this portion of the pad.
The plates normally occupy a position about the shaft 304 in which the plate 288 presses downwardly against the opposite margins of the pad 36. To hold the plates in this position there is secured on each of the opposite sides of the pad box, an upwardly extending pivot pin 306 on on a vertical pin 3|6 also fast on the pad box is which is freely rotatable a. plate clamping finger 308 which is held against vertical movement on the pin. Each of these fingers has an inwardly projecting portion 3H1 arranged to overlie the upper plate 286 near the right-hand end of the latter and, by engagement with this plate, to hold the lower plate 288 pressed against the pad. A bifurcated ear 3| 2 extends to the right from each clamping finger and a screw 3| 4 freely pivoted arranged to extend through the ear M2 and, by means of a nut 318 on its outer end, acts normally to prevent the clamping finger from being swung about its pivot 306 to remove its inwardly projecting portion 3l0 from its position over the upper plate 286.
By slackening the nut 3|8 on. the outer end of the screw, however, the screw can easily be swung to one side about its pivot pin 3l6 so that the clamping finger can also be readily swung about its pivot 306 to move its inwardly projecting portion from position over the plates. When this has been done the upper and lower plates 286, 288 with the masking plate 290 between them, may be swung upwardly about their supporting shaft 304 to a raised position in which they lie clear of the pad so that the latter may be lifted bodily out of the box, the arms 24 carrying the forepart fingers and 22 also rising about their pivots 26. In order to cause the plate 288 to bear upon'a new pad assembled in the box, it is only necessary to swing the plates downwardly to press on the pad, to swing the two clamping fingers 308 so that their inwardly projecting portions overlie the upper plate and to swing the retaining screws 3| 4 for these fingers between their bifurcated ears and to tighten up the nuts 3l8 on the retaining screws.
The heel end portion of the pad has secured to it a thin metal frame 320 (Fig, 2) which extends around this portion and has ears extending from its opposite side portions which overlie the opposite side margins along the heel portion of the pad. At its inner and outer sides and near its heel end the pad box has vertical pins 322 secured to it and on each pin is freely rotatable a clamping finger 324 similar to the clamping fingers 308 previously referred to. These latter clamping fingers 324 have inwardly extending portions arranged to overlie the ears on the metal frame 320 and thus to hold the heel portion of the pad firmly on its bed. These clamping fingers have bifurcated ear portions 326, engaged by swinging retaining screws 328, similarly to the clamping fingers 308.
Thus it will be understood that the pad is retained in place within the box by four clamping fingers arranged two to clamp the forepart portion of the pad against the pad bed, through the superposed plates 286, 288 and two to clamp the heel end portion of the pad against the bed.
Although these clamping fingers are normally retained in operative position by their retaining screws, these latter can readily be swung aside to allow the clamping fingers to be moved to inoperative position so that when the superposed plates 286, 288 have been raised the pad can be readily lifted out of the box and another pad of a different shape substituted therefor.
.The feature of permitting ready removal and interchange of pads in the pad box is not claimed herein since it has been claimed in a copending sole application Serial No. 107,632, filed October 26, 1936, in the name of Lawrence Mawbey, one of the present joint applicants.
