17 Claims.
This invention relates to machines for applying pressure to soles and shoes and is illustrated herein as embodied in a machine for cement attaching soles to shoe bottoms.
5 In many cement'sole attaching machines in use today the pressing devices or pad boxes in which the soles and shoes are placed to receive sole attaching or sole laying pressure are provided with sole and shoe positioning mechanisms operative to position these members relativelyto each other on a pressure applying or pressure sustaining pad in the pad box. These pads are usually fluid filled flexible chambers of rubber or similar material adapted either to be distorted by inflation to apply pressure, or to be distorted by having the sole and shoe pressed forcibly against their shoe receiving walls. In either case,- the sole and shoe and the flexible wall of the pad are moved relatively to each other during the pres- 20 sure applying operation.
It will be apparent from the foregoing that when positioning mechanisms such as gages adapted to engage the opposite sides of a sole or shoe are utilized, there is a grave danger of damaging the shoe upper if. these gages remain in contact with the sole or shoe while the shoe and pad are moved relatively to each other during the pressure applying operation. On the other hand, it is essential that the positioning gages 30 remain in operative engagement with the sole and shoe until at least suificient pressure has been applied to prevent relative displacement of these members before the sole has become attached to the shoe bottom.
An object of the present invention is to provide improved means in a machine of the type referred to for withdrawing shoe positioning mechanism from engagement with the shoe during the pressure applying operation.
To the accomplishment of this object the invention provides, in combination with sole positioning gage mechanism and separate shoe positioning gage mechanism, improved means for withdrawing the shoe gage mechanism only from operative position during the pressure applying operation. As herein illustrated, the gage withdrawing mechanism is constructed and arranged to be operated automatically after a predetermined pressure has been applied to the sole and shoe, this pressure being suflicient to insure that the sole and shoe will not become displaced relatively to each other after the gages have been withdrawn or during the remainder of the pressure applying operation.
In the illustrated construction the sole gage mechanism comprises a tongue for centralizing the sole widthwise of the pad and having a pin for engaging a hole on the longitudinal median line of the sole. The shoe gage mechanism com prises a pair of. gage fingers interconnected for equal and opposite movement and actuated by the engagement of a projection thereon in a cam slot formed in a gage operating slide movable transversely of the pad relatively to the gages. The shoe gage withdrawing mechanism, as herein illustrated, is actuated by the operation of the pressure applying mechanism of the machine and the construction is such that the gage withdrawing mechanism maintains the gages withdrawn from engagement with the shoe until after the pressure on the sole and shoe is relieved.
With the above and other objects and features in view the invention will now be described with reference to the accompanying drawings and will thereafter be pointed out in the claims.
In the drawings,
Fig. 1 is an elevational view of. a portion of the machine embodying the present invention including a pad box and mechanism for applying pressure to a sole and shoe mounted therein, the view being taken looking toward the heel end of the pad box;
Fig. 2 is a plan view ,of the gage withdrawing mechanism of the machine;
Fig. 3 is an elevational view, similar to Fig. 1 but on an enlarged scale, showing the pressure applying mechanism in an operated position;
Fig. 4 is a plan view of the heel portion of the pad box and the sole and shoe positioning mechanism carried thereby; and
Fig. 5 is a detail perspective view of a part of the gage withdrawing mechanism.
The invention is illustrated herein as embodied in a cement sole attaching machine of the type *disclosed in Letters Patent of the United States No. 2,047,185, granted July 14, 1936, on an application filed in the names of. Milton I-I. Ballard et a1. As disclosed in the patent referred to, the machine is provided with a rotary turret l (Fig. 1) having a plurality of radially projecting shelves or brackets l2 upon which are mounted pad boxes l4 provided with sole and shoe receiving pads (Fig. 4) against which a sole and shoe may be pressed to cause the sole to become attached to the shoe bottom. Each pad box I4 is provided with sole and shoe positioning mechanism at its forepart and rear portions for locating the sole and shoe relatively to each other on the pad. Since the present invention is concerned only with the positioning mechanism at the rear or heel end of the pad box, the forepart of the box and the positioning mechanism thereon have not been disclosed. While the invention is illustrated herein with reference to a machine and a pad box of the types referred to, it is to be understood that in its broader aspects the invention is not limited in its use to such constructions but may be applied to other types ofv pad boxes and cement sole attaching machines. The mechanism for positioning the heel portion of a sole on the pad i5 is similar in construc- 1 tion and operation to that disclosed in the Ballard patent referred to and comprises a forwardly extending gage or tongue iii (Fig. 4) pivotally mounted on the forward end of a short horizontal slide l8 and carrying at its forward end a short pin 2!! which projects downwardly from the under side of the tongue and is adapted to engage a hole formed in the heel portion of a sole, this hole being usually located on the longitudinal median line of the sole. The tongue 16 is pivoted on the 'slide- I8 by a pin 22 and is arranged to'swing heightwise of the pad within predetermined limits to permit the sole to be placed'in position to be engaged by the pin 20. A toggle spring 24. extending between the slide and the tongue acts to maintain the latter in either its operative position against the pad or its inoperative position raised from the pad.
The horizontal slide 18 is mounted in a T-slot 26 (Fig. 1) extending lengthwise of the pad in a casting 28 secured to gage supporting mechanism 29 of substantially the same construction as that disclosed in United States Letters Patent No. 2,005,755, grantedJune 25, 1935, on an application filed in the name of Francis J. Better. As disclosed in the Better patent, the sole and shoe .positioning mechanism at the heel end of the pad box is carried by a vertical slide 30 mounted in guideways formed in the right-hand end of the pad box, this slide having a rearwardly extending horizontal bracket 32 at its upper end for supporting the heel end positioning mechanism. Since the construction and operation of this supporting mechanism, including means for adjusting the positioning mechanism as a unit longitudinally of the pad box, and also means whereby the entire assembly may be adjusted angularly about a horizontal pivot to position the gage mechanism relatively to the top surface of the pad, is fully disclosed in the Better patent, no further description of this mechanism will be given herein and referencemay be had to the patent mentioned for a more complete disclosure thereof.
The slide l8 and heel gage or tongue l6 are normally held in a'forward position in the slot 26 by a spring 34 (Fig, 4) engaging a pin 36 on the slide and mounted on a pin 38 projecting down-' wardly from an upper casting 4!! which, together with the casting 28, is fastened to the gage sup porting mechanism 29 by screws 42. Whenthe operator positions the heel portion of a sole A on the pad, he moves the tongue H5 rearwardly of the pad box against the spring 34 and inserts the pin 28 in the hole in the heel end of the sole, the forepart of the sole, as is customary in this type of pad box, being thereafter positioned by the forepart sole and" shoe positioning mechanism. After positioning the forepart of the sole the operator releases the gage l6 and the spring 34 acts to hold the gage forwardly under light tension and thereby prevents the sole from moving rearwardly out of contact with the forepart gages. If desirable, the tension of the spring 34 may be sufficient to cause the shank portion of the sole to buckle slightly away from the pad so that when a shoe B on a last L is placed on the pad, the shank portion of the sole will always engage the shank portion of the shoe before pressure is applied, even though the initial conformation of the pad may not be such as to insure this result in all cases. Since the castings 28 and 48 are fastened by the screws 42 to the gage supporting mechanism 29, the slide [8 and gage l6 are fixed" against movement widthwise of the pad, theposition of these members being such that the pin 29 will centralize the heel portion of the sole widthwise of the pad.
lhe casting 28 is provided on its lower side with a transverse slot 44 (Fig. 4) in which is mounted a slide memberfi. Pivoted on the slide member 46 on pins 48 are a pair of shoe engaging fingers or gages 5,0 which are interconnected for equal movement in opposite directions by intermeshing gear segments 52, this construction being substantially the same as the arrangement of the shoe engaging fingers of the Better patent referred to. Mounted for transverse sliding movement in aslot 54 in the upper casting 431s another slide 56 provided with an inclined cam slot 58 into which projects a roll 68 mounted on a laterally extending portion of one of the gage fingers 50. Transverse sliding movement of the slide 56 toward or away from the operator will cause the roll 60 to be moved forwardly or rear.- wardly of the pad by its engagement with the cam slot 58 and thereby move'the interconnected fingers 50 toward or away from the shoe B on the pad. The shoe gages or fingers 50 may be adjusted transversely of the pad, relatively to the sole gage 16 by, an eccentric adjustment 52 mounted on-the casting 28 and operating on the transverse slide 4B,'this adjusting mechanism being arranged to be maintained by friction in any position into which it may be moved, as fully disclosed in the Better patent.
A cement sole attaching machine of the type embodying the present invention is provided with pressure applying members or abutments for engaging the forepart of the shoe and the top of the heel portion of the last in the shoe and pressing the shoe and sole forcibly against thepad to apply the sole attaching or sole laying pressure. As illustrated in the Ballard et al. patent referred to, these abutments consist of a last engaging abutment 64 (Fig. 3) and a shoe engaging abutment (not shown) adjustably mounted in vertically movable brackets carried by a swinging frame member66. The bracket for supporting the heel engaging abutment 64 comprises an upwardly and forwardly curved arm 58 pinned to a vertically movable shaft Til which is normally supported in its'uppermost position in the machine by a spring 12. .The shaft it, bracket 68 and abutment 64 are moved downwardly relatively to the swinging frame 66 by a pressure applying lever 74 engaging the forward end of the bracket 68' and pivoted on a shaftl'fi in the swinging frame. The lever 14 (and a corresponding lever which operates the forepart shoe engaging abutment) have rearwardly extending'arms '58 which are engagedby the opposite ends of a pivoted lever 80 extending between the pressure applying levers and pivoted in a manner to cause the pressure of these levers against the abutclosed in the Ballard et al. patent, the pressure applying mechanism of the machine comprises 'ments to be substantially equalized. As disfluid pressure operated means which acts upon 75 the pivoted lever when the operator treadles the machine, the part of this mechanism associated with the portion of the machine illustrated in Fig. 1 being indicated generally in that figure by the numeral 82. Since this fluid pressure applying mechanism is relatively complicated and is fully disclosed in the Ballard et al. patent, no further description thereof will be given herein.
The swinging frame member 66 is arranged to be swung by a handle 83 (Fig. 1) from a rearwardly inclined position, in which the pressure applying abutments are removed from over the pad, into a substantially vertical position, as shown in Figs. 1 and 3,- in which the forepart abutment referred to and the last engaging abutment 64 are located over the shoe and in position to be moved downwardly by the pressure applying levers 18 to apply pressure to the sole and shoe. This forward swinging movement of the swinging frame 56 is utilized to move the heel end shoe positioning mechanism into operative engagement with the shoe. This is accomplished by connecting the transverse slide 56 to a pivoted lever 84 (Fig. 3) by a rod 86 having universal connections 88 and 99 with the slide 56 and the lever 84, respectively, the lever 84 being pivoted for free swinging movement on the shaft I6 in the swinging frame 66. In order that the pivoted lever 84 will move the slide 56 forwardly toward the operator to operate the shoe gages 59 during the forward swinging movement of the swinging frame, the pivoted lever is provided with a rearwardly extending projection 92 having a notch 94 therein which is arranged to be engaged by a detent 96 on a rearwardly extending arm of a lever 98 pivoted at I on the swinging frame 66 and normally urged upwardly toward the notch 94 by a spring I02 connected to the lever 99 and to the swinging frame. The construction is such that when the swinging frame is in its rearwardly inclined, inoperative position the detent 95 engages the notch 94. This causes the lever 84 to move the slide 56 outwardly toward the operator as the swinging frame 66 moves forwardly thus moving the gage fingers 5D inwardly toward each other until they engage the opposite sides of the heel portion of the shoe. Upon engagement of the gage fingers with the shoe, the lever 84 becomes disengaged from the detent 99 and, because of the contact of the gages 59 with the shoe, remains in a stationary position during the remainder of the forward swinging movement of the swinging frame. In this way the gages are brought inwardly against the shoe and are maintained in engagement therewith during the application of some pressure thereto. The angle of the slot 58 in the slide 56 is such that the gages are locked against movement away from the shoe after they have con tacted therewith. As disclosed in the Better patent refer ed to, a tension spring I04, connected at one end to the transverse slide 56 and at its other end to the casting 40, causes the to the sole and shoe,- for example, a pressure of twenty or thirty pounds which is suificient to prevent these members from becoming displaced relatively' to each other before the full pressure has been applied, to withdraw the gage fingers 59 from engagement with the opposite sides of the shoe so that, as the shoe is sunk further into the pad. by the pressure applying mechanism, there will be no danger of scarring or otherwise injuring the shoe upper through the engagement therewith of the shoe positioning gages or fingers during this downward movement. Accordingly, in order to effect withdrawal of the gage fingers 56 automatically after a predetermined pressure has been applied to the sole and shoe, the following mechanism has beenprovided.
The last engaging abutment 64 has a shank or stem I96 (Fig. 3) which is supported for sliding movement heightwise of the pad in a carrier member 98 mounted for adjustment lengthwise of the pad in a T-slot H9 formed in the forward end of the bracket 68. At opposite sides of the stem I96 the member I98 carries in appropriate openings a pair of compression springs H2 (Figs. 1 and 2), the lower ends of which bearagainst the abutment 64 and press it downwardly with a pressure determined by the size of the springs. Although this pressure can be varied it is preferably about twenty pounds to the square inch. The abutment 64 is retained in position in the carrier member by a pin H4 which enters a vertical slot (Fig. 3) in the stem I99 and thus prevents the abutment from dropping out of the carrier member or from turning therein. By this arrangement the abutment may yield a limited amount relatively to the carrier member and bracket 68 during the first part of the pressure applying action or until the upper surface of the abutment contacts with the carrier member at which time, as indicated above, the pressure on the shoe will preferably be about twenty pounds to the square inch over its bottom area.
The abutment 64 has a portion extending inwardly from the operator, as best shown in Figs. 1 and 3, and this inner portion is engaged by a vertical pin H6 slidably mounted in the bracket 68. The bracket E58 has a laterally and upwardly extending portion I I8 formed thereon which supports the handle 83. The upper end of the sliding pin H6 engages the outer end of a substantially horizontal lever I20 pivoted at I22 on the bracket 68 and held against the pin by a spring I23 (Fig. 2). The lever I29 (Fig. 3) has an inwardly extending arm pivotally connected by a pin I24 to an upwardly extending link I26, the upper end of which is provided with a slot H8.
The portion H8 of the bracket 68 has an upwardly projecting cylindrical portion I30 in which is mounted for vertical sliding movement a shaft I32 provided on its outer side with ratchet teeth I34. The lower end of the shaft I32 carries a pin 36 which is engaged in slots I38 formed in a pair of ears on an outwardly extending arm I48 integral with the pivoted lever 84.
Adjacent to the vertical shaft I32 and pivoted on a pin I42 is a pawl I44. The pawl has an arm carrying a pin I 46 which rides in the slot 28 in the vertical link I26. The pawl is normally urged in a counterclockwise direction, as viewed in Figs. 1 and 3, to move it into engagement with the ratchet teeth E34 by a spring I 48 connected to the pawl and to the portion 552 of the bracket 68.
When the mechanism is in the position shown in Fig. 1, the pin I49 of the pawl bears against the lower end of the slot I 28 and the pawl is thus held out of engagement with the ratchet teeth on the Wise in the portion I30 of the bracket 68. After the sole and shoe have been relatively positioned on the pad and the treadle of the machine has been operated to cause the pressure to be applied to the shoe, the two levers I8 move the brackets 68 carrying the shoe and the last engaging abutments downwardly against the springs I2, as explained above. The last engaging abutment 64 yields upon engagement with the last against the springs I I2 until the upper surface of the abutment contacts with the carrying member I08. This action moves the pin I I6 upwardly to cause the lever I to swing in a clockwise direction, as viewed in Fig. 3, about its pivot I22 to lower the vertical link I26 and thereby free the pin I46 in the pawl I44 so that the spring I48 can swing the latter into locking engagement with the ratchet teeth on the shaft I32.
It will be seen from the above that during the first part of the downward movement of the castings 68 and the last and shoe engaging abutments, the shaft I32 does not move downwardly owing to its connection with the arm I40 of the pivoted lever 84 which, it will be recalled, is held stationary due to the contact of the shoe gages or fingers 50 with the opposite sides of the shoe. The. abutments will apply a predetermined pressure to the sole and shoe during this downward movement depending upon the strength or resistance of the springs II2 acting on the last engaging abutment 64. After the pawl I44 has been moved into engagement with the ratchet teeth on the shaft I32, the latter becomes locked to the downwardly moving bracket 68 and the portion I30 thereof and consequently moves downwardly with it as a unit during the remainder of the pressure applying operation. Downward movement of the shaft I32 swings the arm I 46 and the pivoted lever 84 in a counterclockwise direction, as viewed in Fig. 3, to move the rod 86 and the transverse slide 56 inwardly away from the operator and thereby to cause the gage fingers 50 to move out of the operative position shown in broken lines in Fig. 4 into the open position shown in full lines in that figure. Consequently, the gage fingers 50 are withdrawn from operative or shoe engaging position to a retracted or inoperative position and are maintained in such retracted position during the remainder of the pressure applying operation.
After the pressure applying operation has been completed the abutment 64 and its supporting bracket 68 are permitted by the pressure applying lever I8 to be moved upwardly by the spring I2 away from the last and shoe. This permits the abutment 64 to return to its initial lower position relatively to the member I08 which, through the mechanism already described, causes the pawl I44 to be withdrawn from engagement with the shaft I32, thereby permitting the latter to be moved upwardly by contraction of the spring I04 on the transverse slide 56 so that the shoe gages 50 move inwardly again into engagement with the shoe.
After pressure has been relieved on the sole and shoe, the swinging frame 66 returns automatically to its rearwardly inclined, inoperative position. This swinging action of the frame member 66 moves the pivoted lever 84 about its pivot into a position that permits the detent 96 to become engaged again in the notch 94 and thereby connect the pivoted lever with the transverse slide 56 and the shoe gages operated thereby. Consequently, the remainder of the rearshaft I32 so that the latter is free to slide height ward swinging movement of the swinging frame causes the shoe gage fingers 50 to be retracted positively by the gage operating mechanism into their open or inoperative position. The shoe B with its sole A cement attached thereto throughout the forepart and shank portions of the shoe bottom may now be lifted from the pad and the pin 20 on the gage I6 disengaged from the hole in the heel end of the sole. A fresh sole may then be mounted on the pad and positioned as described above prior to its attachment to a shoe.
