Application led May 15, 1918. Serial No. 97,516.

To all whom z't may concern.'

Be it known that I, ANGELO PERRI, a citizen of the United States, residing at Groveland, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Lasting-Machines, of which the following is a speciication, reference being had therein to the accompanying drawing.

This invention relates to lasting ma- Y side margins and the margins at the heel and toe. Such wiping consists in forcing, smoothing and pressing the overhanging material of the upper into place about the last and sole, where it may be suitably secured preparatory to subsequent operations includlng attachment of sole and upper. In my prior Patent No. 1,168,963, granted January 18th, 1916, I have shown a machine in which all of the above described steps -or operations may be performed, the machine comprising a shiftable jack which holds the shoe, a pulling-over mechanism, and heel and toe wiping mechanisms.

The present invention pertains more especially to a wiping mechanism adapted to use at the heel end of the shoe, although various features hereof might be eieetively otherwise employed; and the principal object of the present improvement is to. alford a lasting machine which will be simple and durable in construction and of maximum efficiency and convenience in operation.

The present application, therefore, discloses one form or illustration of a heel wiping mechanism embodying the resent invention and of a lasting machine including the same. The invention may be variously employed. As herein disclosed, it is more especially designed to be employed in a so-called bed lastingvmaehine, in which the inverted shoe is inserted after having been pulled over and in which usually both l there shown.

the heel and toe portions of the shoe upper are wlped and secured. On the other hand, the mechanism hereof may be substituted in such a machine as that of said Patent No. 1,168,963 for the heel wiping mechanism Or the mechanism hereof might, in some cases, if desirable, be employed by ltself solely for the wiping of eels of shoes.

The heel wiping mechanism herein illustrated is shown for convenience of such design as to be particularly adapted to employment in a bed lasting machine, and for this, purpose to be combined with a jack or work holder which properly holds the shoes, and a toe lasting or wiping mechanism arranged in suitable relation thereto. However, the toe wiping mechanism is not herein shown in complete detail, and neither is the jack mechanism, as these are the subjects oi separate patent applications, to which reierence should be made for further details. The ,toe wiping mechanism is completely illustrated and explained in my copending application Serial No. 83,540, filed March 11, 1916, and the jack mechanism in application No. 96,748, filed May 11, 1916.

Indeed, the shoe holding jack, toe wiping mechanism and thev heel wiping mechanism are in reality combined as a single machine, and therefore the three patents may Jfor convenience be considered in conjunction with each other.

Among the particular objects to which the present invention is directed is to provide a heel wiping mechanism adapted to efficient and convenient use for the wiping of both shoes, that is, the right and left shoes yof a pair. A machine which may be quickly`changed over for this purpose is very advantageous in permitting both shoes of a pair to be completed before operating on other shoes.

It is another object hereof toprovide a lasting machine wherein the wiping mecha# nism ma be bodily swung upon' mountings indepen ent ofthe mountings of the jack and substantially about the apex of the wiper plate contour as a center in order to set 't e line of wiping action into proper relation or coincidence with the center. llne of the shoe at the end.

Another object is to provide a lasting machine wherein the readjustment of the jack,

y operate with a shoe holdin whether automatic or otherwise, for rights and l'efts,l performs an automatic adjustment upon the wiping mechanism to coperate therewith; particularly that the lateral Swingin of the jack will reset the line of action o the heel wiping mechanism so as to lie in a line coincident with the center line of the heel part of the shoe.

Another object hereof is to provide a wiping mechanism for one end of the shoe, particularly the heel end, adapted to cojack, and wiping mechanism for the ot er end, of the character described in my said copendmg application; involving a jack capable of transverse swinging, so as to bring the shoe apex line always in the same longitudinal axis when readjusting for rights and lefts, or for changes in style, particularly a jack which swings about a vertical axis near the shoe heel apex, so as to bring the shoe toe apex into line therewith, or to a particular point at .which the toe wiping mechanism can be readily adjusted by a swinging motion about the apex of the toe wiper contour into alinement with the shoe toe center line.

' Another object is to provide such a heel wiping mechanism ca able of coperating with such a jack by adjustment of the angle of wiping action about the apex of the heel wiper plate contour. This is contrary to a swinging adjustment about a fixed axis in the machine, wherein the axis would not advance and retreat with the heel wiping head.

Another object is to provide that the transverse swinging of a shoe holding jack may automatically determine the angle of wiping action; so that adjustment of the jack to strai hten the shoe apex line for shoes of di erent shape ywill correspondingly chan e the angle at which the heel wipmg mec anismy is set so as to bring it in alinement with the shoe heel center line.

Another object is to provide an automatic adjustment of the heel wiping mechanism such that, when the jack is reversed in positionwhen changing from right to left shoes, and vice versa, the wiping mechanism will be correspondingly and symmetrically reversed.

Another object is to` similarly provide that.

of the wiper plate contour, so that changes of tilt will not substantially alter the altitude of the wiper plates.

Another object is to provide a wiping mechanism wherein4 the adjustment of the angle of wiping acti-on, and also the adj ustment of longitudinal tilt of the wiping plates, and also adjustment of the lateral tilt thereof, are all effected about axes passingl substantially through or near the apex of the wiper plate contour.

Another object is to provide mechanical connections for effecting respectively the longitudinal tilting and thc lateral tilting adjustments of the wiping mechanism, which will be simple, effective, and easy and convenient of operation.

Another object is to rovide adjusting means operative indepen entlv of the main tilting mechanism for laterally tilting the wiping plates about one edge or the other.

Another object is to provide means` for advancin or setting back the initial wiper plate position, so that the plates will stand 1n proper position to the shoe when Vcommencin the Ywiping operation.

Anot er object is to provide adjusting' 4to objects and advantages the present invention consists in the novel lasting machine or wiping mechanism, and the novel features of arrangement, design, combination and detail herein illustrated or described and claimed.

Generally speaking, a bed lasting machine such as that indicated herein may comprise a base 19, u on which are supported the jack o`r shoe ho ding mechanism 21, and to the right of the jack the heel wiping mechanism 22, and to the left ofthe jack the toe wiping mechanism 20. j Since the novelty of the invention is not restricted to the construction of the heel wiping mechanism, but lies also in the comjack and toe wiping mechanism, it will be necessary to describe the three mechanisms. The jack and toe wiping mechanism, however, being completely described in my copending applica.- tions, need not be so fully described herein. It will be convenient to first generally refer to the toe wiping mechanism, and subsequently describe the jack and the heel wiping mechanisms. The same reference numerals will be employed for all three patents.

Referring first to the toe wiping mechanism 20, the description in said application 183,540 may conveniently be condensed as folows:

At the left of the bed is an elevatable support 23, which may be lifted and lowered by a pedal 245 during wiping operations. Sliding on the support 23 is a carriage 25, which may be shifted toward and from the shoe by a hand-wheel 26. Upstanding from the carriage are brackets 30, which at their upper ends give support to the toe wiping mechanism or head. At the extreme right of the toe wiping head is seen one of the wiper plates 61.

vThe movements and adjustments of the toe wiping mechanism are various. In addition to the longitudinal adjustment toward l and from the shoe by the hand-wheel 26 and leo the lifting and lowering movements by the pedal 24, the toe wiping head 20 is capable of being bodily tilted longitudinally to different Vdegrees from the horizontal by a hand-wheel 36. `Also the wiper plates are designed to have operative movements toward and from the shoe, effected by hand lever being lasted.

'r1-plates being accompanied by a convergence thereof and their retreat by a swinging apart or divergence. Another movement or adjustment, and one which 'is characteristic of this toe wiping mechanism, is an inversion, eiected by handle 130, by which the single set of wiper plates is adapted from one shoe to the other, the inversion insuring symmetry of contour. Also, the advancing and retreating wi er devices are so arranged as to be adjustab e to various inclines from the longitudinal axis of the machine. This is necessary from the fact that shoes are seldom straight, andthe centerline of the shoe forepart extends at various inclines from the center line of the rear part. This is peruformed in a characteristic way, the swing of the mechanism takin place. about a center substantially coinci ing with thetip or apex of the contour of the wiper plates. y'llhe mechanisms are so combined and harmonized that the inversion of the wiper plates to reverse them in changing from one shoe to another simultaneously and symmetrically reverses the direction or incline of wiping action. w

The change of incline of wiping action is effected by mounting the wiper plates and their supporting devices upon a laterally shifting carriage 45, which engages with arcshaped tracks struckabout the center F,

which is the apex of the contour of the wiper plates. The adjustment may be actually effected by hand-wheel 120 and suitable connections, which serve to throw the carriage 45 to or from a true longitudinal position to the degree required by the particular shoes Coming now to the jack mechanism 2l, this, as already explained, comprises shoe supporting devices permitting the shoe A to be swung horizontally about a vertical axis or center located at D near or approximately at the ti or apex L of the shoe heel. See Figs. 1 an 6. This permits the forepart of the shoe to be swung toward and from the operator, or transversely to the longitudinal axis ofthe machine in adapting it and the shoe to the toe wiping mechanism. It has been explained that the adjustment of the angle of action of the toe wiping mechanism 1s performed about the point or center F as an axis, F being the apex of the contour of the toe wiper plates. This point, of course, advances and retreats during the wiping movements. When the plates have been brought up into contact and conformation with the toe of the shoe, the apex F of the plates will coincide with the apex of the shoe toe, which latter may be designated F. See Figs. 1 and 6. Since the bodily adjustment of the toe wiping mechanism toward and from the shoe is longitudinal-in direction, it follows that the point F, and therelll@ fore the point F', when the lates are in position to conform with the s oe, will always be in the longitudinal axis H of the machine. In other words, every shoe, straight or crooked, right or left, placed in this machine will be so located that the line F-D joining the apexes of the toe and heel will be constant in location and direction.

In order to bring the shoe into the position indicated, the jack will be swung about the center D until the shoe toe a ex l lies in the longitudinal axis H-H. his will be indicated by the coincidence of the Wiper plate apex F and the shoe toe apex F. In this lateral swinging of the 'ack for rights and left-s and for dlferent s apes and styles of shoes, the jack assumes diiferent positions, which may be indicated b axis of the jack itself. T is axis will seldom coincide with the longitudinal axis H-H; in fact, never, unless with an absolutely straight last. Thus, in the supposed instance the forepart of the jack has been swung out into the direction D-J, which represents the axis of the jack for the left shoe A. The adjustment of the toe wiping mechanism about the center F is readily made, so that the wiper plate contour will conform with the shoe toe and so that the angle of wiping action will substantially coincide with the center line of the forepart of the shoe, as indicated.

The readjustment for a right shoe the mate of the left shoe A would be easily effected by a mere symmetrical shifting of both the jack and the wiping mechanisms.

When a change in shoe style is made, a

different readjustmentis made. The more s nearly strai ht the shoe, the more nearly will the jac axis be adjusted toward the longitudinal axis.

With the above explanation of the character of the jackl as 1t coperates with the toe wiping mechanism the subsequent description of the relation of jack and heel wiping mechanism will be better understood.

The structure of the jack mechanism is sufficiently shown in Figs. 1 and 6. It comprises toe and heel rests 155 and 156 mounted at the upper side of a swingable base plate 157, which is of generally square form and located above the top plate or bed of the machine base 19. The jack base late is transversely movable at the toe en by swinging about the center or vertical axis D, located substantially at or near the a ex of the heel of a shoe or last held on the jack. The heel rest is adjustable on the base plate toward and from the toe rest. The base plate also carries a hold-down device comprising the hooked arms 170, which serve to clamp a shoe in position upon the toe and heel rests.

To permit the swinging movements referred to, the jack base late, carrying the two rests and the hold-down device, 1s selaying out the cured to a vertical shaft 158 coincident with the axis D, before mentioned.

The details of the toe and heel rests and the hold-down mechanism are unnecessary to set forth in full, since per se they form no part of the present invention, but do form part of the invention claimed -in said application No. 96,748, in which the same are ully described. It is sufficient to explain that a pedal 185 is employed, which -controls the hold-down or clamp mechanism, the depression of the pedal pulling the hold-down hooks firmly upon the shoe and the parts becoming locked b as ring-pressed locking lever 196, releasa le y its upper endor handle 197.

As further explained in said application No. 96,748, the depression of the pedal 185, actin through the lever 187 and connector or ro 189, serves not only to apply and lock the hold-down hooks, but also to lock the jack heel rest against longitudinal movement and the jack base plate against swinging movement.

To regulate the extent of swing or incline of the jack, which may be effected by hand or automatically, I may employ symmetrically adjustable sto s, asexplained in said application No. 96, 48, adjusted by hand:

wheel 203. Instead of `throwing the jack across from one side to the other in changing from left shoes to right, and vice versa, an automatic arrangement may be employed for effecting this result at each operation of the pedal 185. Generally speaking, this mechanism operates by rocking the vertical fulcrum shaft 158 through a cam and roller device, actuated from the pedal through the lever 187 and connecting rod 2 11, as more completelyv described in said application No. 96,748.

The heel wiping mechanism or head 22 will now be more particularly described, this being of a character adapted to coperate `with the character of jack mechanism previously described, which in turn is adapted to coperate with the character of toe wiping mechanism,.previously described.

The` coperation between the 'ack and heel wiping mechanism is fourfold. in the illustrated embodiment of the present invention.

Thus, firstly, the jack in accommodating a shoe to the toe wiping mechanism swings `about the center D, which is located near or practically coincident with the apex L of the heel of the shoe. By this arrangement the'shoe swings during the adjustment, but the shoe heel apex L"1s to all practical purposes fixed. In coperation with this arrangement the heel wiping mechanism is arran ed to bodily swing so as to change the ang e of wiping action, this swinging being eifected,'not about a fixed axis in thema-l chine, but about the apex L of the contour maaier of the heel wiper plates.` This axis or apex L is a movable onez it being carried toward and from the shoe 1n the bodily adjustment isinvolved or adjusting of the jack angle of wiping action. This arrangement,

in making sli ht adjustments in the position of the jac to correspond with changes in the style or curvature of shoes, relieves the operator from exercising his judgment in resetting the heel wipin mechanism to conform with the new ang e at which the shoe is held.

Thirdly, the reversal of the incline of the jack from one side to the other of the longitudinal axis of the machine in changing over from right shoes to lefts, and vice versa, determines or eects a corresponding reversal of the heel wiping mechanism. This relieves the operator of one adjustment usually necessary in changing from rights to lefts, yand vice versa, and therefore -tends to render more convenient and practical the plan of wiping right and left shoes alternately, so as to permit the completion of one pair of shoes before proceeding with another pair.

Fourthly, as shown in the accompanying drawings, the reversal of the jack, or throwing it across from one side to the other for rights or lefts, is-caused to determine or effect the symmetrical reversal of the lateral tilt of the heel wiping lates. 1t will be understood that for the rst shoe of a pair the operator carefully adjusts thelateral tilt. When the other shoe is operated on, the

tilt must be reversed, and this operation is automatically taken care offherein through the act of reversing the position of the jack when one shoe is changed for another.

In fact, it will be observed that the operations of the pedal 185 in unclampin one shoe and clamping the mate automatlcally perform the symmetrical reversal of the jack, and also the symmetrical reversal of the angle of heel wiping action, and also the symmetrical reversal of the lateral tilt of the heel wiping plates.

It will be convenient to describe in a general way the attainment of the above mentioned features of coperation before describing the details of the heel wiping head. As seen partly in dotted lines in Fig. 6, the

ine automatically deterheel end of the jack base plate 157 is provided with a longitudinal extension or tail 231. Its upper side is provided with a longitudinal s ot or guideway formed between opposmg side parts 232.I These side parts are tapered at their rear ends to give an entrance to the uideway or groove. It will be understoo that, whenever swings transversely about the axis D for throwing the toe end thereof frontward or rearwar the extending tail 231 will swing rearward or frontward, the toe end ofthe jack.

The groove formed between the guide walls 232, 232, of the swinging jack extension is for the purpose of engagement by a stud or roller 230 extending downward between. the guide walls from a transversely swmgmg carriage 228, fitted by means of curved ribs or guides 229 to receive a movement about the a'pex L of the heel wiper plate contour as a center.

rllhe guiding extension 231 of the jack, therefore, either directly effects the swinglng of the carriage from side to side, as requlred to adjust the angle of wiping action, or, if the stud 230 should have been retracted from engagement with the guiding extenslon, it determines the`positi0n of the carriage and wiping angle upon the rentry of the stud into the groove between the guide walls 232, 232. Moreover,this swinging adjustment of the carriage 228 automatically takes place either in the case of a slight change in the jack incline for changes of shoe style, or in thecase of throwing the jack transversely across the machine from one side to the other in changing over from rights to lefts, and vice versa.

The symmetrical reversal of the lateral that is, reversely to tilt of the heel wiping plates is effected, by`

connections later to be described, by the act of symmetrically reversing the carriage 228 and the line of wiping action; and is therefore either determined or effected b'y the adjustment or readjustment of the jack.

The heel wiping mechanism 22 may described in detail as follows: At the end of the machine is arranged a rising and falling support 218 similar tothe support 23 of the toe wiping head at the other end'. The support 218 may be lifted or lowered to alter the altitude of the heel wiping head by means of a handle or crank 219operating through a shaft 220 geared to a vertical screw shaft 221, having threaded connection with the rising and falling support.

At the top of the support 218 is a longitudinally sliding frame 223, by which the wipin head may be bodily shifted toward and rom the work. This frame 223 is slidably mounted in longitudinal ways on top of the .support 218, similarly to the frame 25 at the other end, which carries the toe wiping head. To effect the longitudinal the jack.

bei

shifting of the frame 223,it is provided with a toothed rack 224 engaged by a 1n1on on the shaft of a hand-wheel 225. locking lever 226 is indicated, this servlng to hol the frame leftward when adjusted to the work.

Above the longitudinally sliding frame 223 is a transversely swingable carriage 228. This travels upon curved bearing ribs. or dovetails 229, which, as seen 1n Figs. 3 and 6, are struck about the apex L of the heel wiper plates as a center. By this arrangement the lateral swinging of the carrlage 228 into diiferent angular positions alters the angle of wiping action without changing the position of the center or apex L of the wiper plate contour. Downwardly extending from the swinging carriage 1s the stud or roller 230, previously mentioned, '(see Fig. 5). This stud 230, as before explained, extends into engagement with the guiding extension or, tail 231, for example, between the guide walls 232, which at the upper side of the extension form a guide groove, tapered at the extreme right end to facilitate the entrance of the stud therernto.

By this construction the positioning ofthe jack determines or effects the transverse swinging of the carria e228 and accurately sets the angle of wiping action to accord with the position in which the shoe may be held in the machine. In Figs. 1 and 6 the heel wiping head is shown moved to the left or brought up to the wipmg position. When retracted by turning the hand wheel 225 to slide the entire frame 223 to the right, the stud 230 will easily pass out of engagement With the uide extension of the jack. The manual a justment of the jack for changes in style may be effected while the head is thus retracted. The flaring entrance to the guide groove insures correct rengagement of the parts. The symmetrical reversal of the jack for rights or lefts is preferably effected while the stud is engaged in the v guiding extension, in which case the transverse shifting of the jack actually effects the corresponding swinging about the center L of the carriage 228. v

The carriage 228 is provided with upstanding side brackets 234 having trunnion bearings 235 at their upper ends, between which aretiltingly supported certain further parts to be described.

Directly trunnioned on the bearings 235 is what may be called a longitudinally tilting shell 237. This is generally of the shape of a portion of a ring, so as to afford circular bearing surfaces for the parts contained within, which are intended to be laterally tilted. The shell is irregularly shaped for accommodationwith the various associated parts, but does not require a detailed description. One point, however, which shoild be noted, is that the axis aboutwhich the shell 237 tilts, namely, the

axis of the trunnion bearings 235, 1s a trans-` i N -N a suitable degree of tilt, although for convenience in Figs. 2 to 10 the parts are illustrated without tilt. In Fig. 1 the toe and heel wiping mechanisms are both shown as slightly tilted, as required by the shape of the shoe or last.

Next will be described the laterally tilting carriage 240, which has a rocking movement within the circular shell 237 the actual connections for el'ectin the longitudinal tilting of the shell an the lateral tilting of the carriage being left to a later point.

The carriage 240, which is shaped to be accommodated within the concave interior of the shell 237, is a built-up structure comprising three latwise plates, 241 beneath, 242 1n the middle, and 243 forming a cover at the top. These three plates are rigidly bolted together to form a unitar structure, but are vertically spaced apart rom eafh other .to afford a horizontal space above the bottom plate to accommodate the ttings for .the heel clamping devices, and a space between the middle plate and cover to accommodate the fittings of the heel wiper lates, including the carrier which is mova le to and fro lon itudinally to carry and actuate the wiper p ates in the wiping o eration.

The three constituent plates o the laterally tilting carriage are suitably rovided with finished convex bearing surflslces 244 adapted to en age the finished interior bearing surface o the shell 237, and, indeed, the top and bottom plates are enlarged at 244 to ive a more extended bearing surface..

he built-up carriage 240 is held against longitudinal movement in the hollow shell by means of shoulders 245 near the forward or left ends of the plates and by attached triangular retaining plates 246 near the rear, (see Figs. 8 and 7). l

Referring n'ow to the heel clamping devices and` their fittings contained between the carriage plates 241 and 242, the details are best seen in Fig. 9, top view, "Fig, 4, left end view, and Fig. 5, central section. These are arranged on a plan similar to that disclosed in Fig. 25 of my prior Patent 1,168,963, wherein a central clamp member or heel abutment pad at the longitudinal axis is adapted to meet the shoe or last as lli maaier the clamping mechanism isy thrust toward the slioe, and by relative movement of a wedge or cam to force the side clamp members toward each other against the sides of the shoe or last. This action takes place when the wiping head is thrust bodily leftward by the hand-wheel 225, the parts becoming locked, as already explained, so that the shoe is rigidly clamped by the heel wiping head after the various tilting and swinging adjustments have been perfected and prior to theoperative movements of the wi er plates.

eferring to the drawings, the central heel clam member or pad 248, which may be terme an abutment, is ivoted at'the forward extremity of the sli e bar 249, arranged to slide longitudinally in ways 250 at the. upper side of the lowest carria e plate 241. A spring 251 within a recess in the slide bar bears at its right en'd against a fixed screw, its forward end tending to press the heel abutment relatively leftwaid.

The slide bar 249 also carries a wedge cam 252, the action of which is to force the side clamp members together. This cam is axially pivoted to the bar to permit rocking of the cam for equalization of clamping pressure against the sides of the shoe.

The side clamp members 254,'like the rear member, are pivoted to permit rocking, and thus allow an equalizing adaptation to the shape of the shoe. Each side clamp member comprises a two-part block 255 consisting of upper and lower halves riveted to ether. The block 255 is pivotally connecte by a head and socket joint 256 to its carrying lever 260. This permits horizontal rocking for purposes of adaptation. At the inside of each side clamp block are a plurality of clamp pads 257. Three of these are shown at each side. They are capable of rocking in a vertical direction about horizontal pivots 258 inclosed between the upper and lower halves of the clamp blocks`255.

Thus, the surface of each side clamp is ca able of universal adaptation, each clamp being bodily capable of rocking as a whole horizontally about a vertical axis, and each of the several ads being Icap-able of rockin vertically about a horizontal axis.

prings 259 between the side clamp members 254 and their respective carrying levers 260 tend always to swing the clamp mem-y bers into the position shown in Fig. 9, but to permit yielding in adapting themselves to the shoe.

The carrying levers 260 swing about pivot studs 261 located in the middle part of each lever, and the far extremities of the levers are provided with cam rollers 262 adapted to engage the wedge cam 252, previously mentioned. Springs 263 act upon the levers 260, tending to hold the rolls 262 against the cam.

By the described arrangement, when the heel wipin headis bodily thrust toward the shoe, the s oe heel is contacted by the abutment pad 248, with the result that the slide bar 249 moves relativel to the right, so that the wedge cam 252 t rusts the cam rolls apart and forces the side clamp members 254 toward each other. When the clam members have become snugly seated against the heel of the shoe, the movement ceases and the parts are locked in osition.

It is sometimes desira le to relatively adjust the side clamp members to allow for diderences in the width of shoe to enable such adjustment ll have provided means for slightly shifting the pivots of the side clamp member carrying levers. Each pivot stud 261 consists of an eccentric disk mounted at the 'top end of a short vertical shaft 265, rotating in the carriage bottom plate 241. The shafts 265 at the two sides extend downwardly through the bottom plate, where they lare provided with toothed wheels 266. A worm shaft 267, having reversely arranged worms, engages the two toothed wheels, so that, when the shaft is turned by the hand-wheel 268, the pivot studs 261 are shifted symmetrically apart or together. As seen in Figs. 1 and 2, the brackets 234 are recessed to accommodate the worm shaft 267 and permit play thereof during ltilting adjustments.

vThe heel wiper plates 270 have'their fittings between the middle plate 242 and the cover plate 243 of the'laterally tilting carriage 240.v Fig. 3 shows them-in top view, as also does Fig. 8, but with the cover plate removed.` Fig. 4 indicates the wiper plates in left elevation, and Fig. 5 in central section.

Referring first to Fig. 8, the two wiper plates 270, 270, are seen to be mounted in a manner similar to that showin in Fig. 31 of my prior Patent 1,168,963, and claimed in claims 41 and 42 thereof. That is to say, the two wiper plates, although relativel swingable, present a continuous wiping e ge at all times during the wiping action, the swinging being provided for y an annular bearing arrangement located at a substantial radius from the meetingpoint of the plates, which is preferably the apex L of their contour. Thus, the annular bearing herein is provided by slots 271 in the respective plates engaged by curved extensions or ribs 272, constitutin the bearing and being formed or attac ed at the forward or leftliand extremity of an advancing and retracting carrier 272 in the form of a sliding bar arranged between guideways 273 at the top side of the plate 242.

The simultaneous and symmetrical swinging of the wiper plates toward and from each other may be eifected by a curved rack I 274 provided on each, these racks engaging heels, and

tionary by means of rods or links 277.

By this arrangement the relative advancing movement of the carrier 272, that is, a

movement toward the left in Fig. 8, serves not lonly to advance the wiper plates, but causes the rotation of the toothed members 275, which act on therracks 274 so as to swing the wiper plates in unison.

These actuating movements of the wiper plates ma conveniently be effected b hand through t e following connections: he top side of the wiper plate carrier 272 is. provided with an upstanding block or boss 278, which passes through a longitudinally extending slot in the cover connected by a link 279 with the operating hand lever 280 pivoted at 281 to the top side of the cover plate 243.

After the insertion of any given pair of heel wiper plates in the machine, it may be found that aI slight bodily adjustment of them toward the work will give a more 'effective wiping. As will be seen in Fig. 8, when the wiper plates are retracted, their longitudinal edges come into direct contact or abutment with each other. While in this position they may be set bodily forward or toward the work, according to this inven-A tion, by sli htl shiftililgisforward the rods or links 27 hess l' extend from the toothed members 275 to an adjustin cross bar 282. If this cross bar be a justed toward the shoe, such adjustment moves forwardly the links 279, the toothed members 275, the carrier 272 and the wiper plates, and also the operating lever and connecting link.

For convenience the adjusting cross bar 282 is fitted to a block 283, fitted between the same guideways 273, before mentioned. An adjusting screw 284 passes through the block 283 and into the threaded portion of a 285 upstanding from the carriage middle late 242. At the righthand end of the bloc 283 is provided a plate 286, which engages a groove or collars on the adjusting By this arrangement a slight initial adjustment of the ad'usting screw 284 will alter, as described, t e forward set or posi- V tion of the heel wiper plates and actuating mechanism.

We come now to the connections and control mechanism by which the longitudinal tilt of the tilting shell 237 is effected and the lateral tilt of the tilting carriage 240.l

late 243 and is ployed in the adjusting of the lateral tilting. Also, associated with such mechanisms are means whereby the reversal of the wiping mechanisms for rights or lefts automat1- callyl effects the lateral tilt in one direction or t e reverse; also means for independently varying the. lateral tilt by liftin or dropping t e wiper plates at one si e without changing their position at the other side of the heel.

The connections to be described extend in part from the longitudinally sliding frame 223, so that the swinging of the carriage 228 transversely of the frame will have an operative effect to reverse the connections with respect to the lateral tilt of the carriage 240. Other portions of the connections to be described extend directly to the laterally tilting carriage 240. The lconnections, in fact, are symmetrical and extendl substantially to the two corners of the carriage 240 which are farthest removed from the wiper plates. By effecting the adjusting operations from these two corners, the corners may be raised or lowered in unison to change ongitudinal tilt, or one may be raised or lowered relatively to the other for changing lateral tilt.

The longitudinal tilt is effected by ahandwheel 288, (see particularly Fig. 7, 4righthand elevation; also Figs. 3, 5 and 2). The hand-wheel is at the upper end of a thread- -ed Vshaft 289, fitted against longitudinal movement in up er and lower bearings 290, formed integral y with a cross bracket 291 secured rigidly to the longitudinally slidable frame 223 on which the carriage 228 swings.

The rising and falling movements are effected by the hand-wheel 288 through a toggle lever arrangement at both sides of the threaded shaft. This is best seen in Fig. 7. A threadedsblock or nut 292 moves up and down on the shaft 289 when the hand-wheel is turned. This block is connected at either side by a link 293, extending upwardly at an incline to a ivot or stud 294. The toggle is complete b an arm 295 connecting the extremity o the bracket 291 with the pivot stud 294. It will -thus be seen that the two pivot studs 294 at the front and rear sides of the axis of the machine will rise or fall in unison with the turning of the hand-wheel. These two studs are connected respectively to separated points at the righthand extremity of the carriage 240. Thereby the operation of the hand-wheel is to lift or drop the swinging extremity of the carriage and the longitudinally tilting shell 237 which supports it.

As before' explained, there are two modes of effecting lateral tilting. The first eifects a decided tilting, which is adaptedl to be symmetrically reversed when the swinging carriage is thrown across for changing from rights to lefts. The other adjustment is a supplemental adjustment on a small scale adapted to slightly lift or lower one side edge of the wiper plates independently of the other in finally conforming the wiping mechanism to the shoe heel. A

The laterally tiltable carriage 240 has secured to its bottom plate, asseen in Fig. 5, a rightwardly projecting bracket 298 ofirregular shape having dovetails 299, on which are slidable a pair of blocks 300, held in place by a right and left threaded adjusting shaft 301, journaled in the bracket 298 and having at its front end a-handwheel 302. Turning the hand-wheel throws the blocks 300 toward or from eachother. Fig. 7 and the other figures shows the blocks spaced directly above the pivots 294, previously mentioned. In this adjustment there will be no lateral tilting, but, as will later appear, a readjustment by the hand-wheel g 302 will effect a lateral tilting that will be automatically reversible upon changing over the machine from rights to lefts. The blocks 300 are connected by compound links 303 with the pivot studs 294. The blocks and links are connected by a sliding pivot arrangement, consisting of a slotted or yoked hea 304 at the top of the link 303, engaged by a sliding plate 305 pivoted on the face of the block 300.

The sliding between the described parts is for the purpose of the final adjustment of lateral tilt, before mentioned. The top of the slotted head ofthe link 303 has fitted to it a thumb nut 306, which extends downwardly into threaded engagement with the sliding plate 305. The thumb nuts 306 at the two sides are shown adjusted to the same position, so that the links 303 are effectively of the same length and the wiper plates are level, having no lateraltilt. Turning either of the thumb nuts one way or the other will correspondingly lift or drop the wiper mechanism at that 'side for the purposes referred to.

It will now be explained how the turning of th hand-wheel 302 changes the lateral tilt o the heel wiper plates and how the chan e in tilt thus eiiecte'd by the handwhee is automatically reversed in changing the machine over from rights to lefts. Observing Fig. 7, it will be seen that in eect we have a parallelogram of links. The studs or pivots 294 are relatively stationary, their position upon the sliding frame 223 havin been determined by the hand-wheel 288. Xtending upwardly from the pivots 294 are the links 303, whlch are parallel and which at their upper ends are pivoted respectively to the blocks 300. If, with the parts in this adjustment, the swinging carriage 228 is thrown to the rear or front, that is, to the right or left in Fig. 7, the links 303 will swing, but will preserve their parallelism and will maintain the blocks 300 always at ecpual altitudes, so that the upper side of the parallelogram is always horizontal and the/carriage 240 is not laterally tilted.

Suppose, however, the hand-wheel 302 is turned so as to throw the blocks 300 farther apart. This adjustment preferably will be made while the swinging carriage is in its proper wiping position. We may,.however,

'suppose the adjustment to be made with the parts centralized, as in Fig. 7. When the blocks 300 are thrown apart, the links 303 will diverge and the arrangement of the parts may be diagrammatically represented as in Fig. 10. The links or arms 293 and 295 hold the pivots 294 rigidly over the frame 22,3. It is understood that the laterally tiltable carriage 240 is above and swings transversely of the machine when the carriage 228 swings. When the blocks 300 have been adjusted from each other, the links 303 diverge, as shown. As in Fig. v7, the parts are shown centrally positioned in Fig. 10. The Swingin carriage has not been swung to either side of the axis.

Suppose, now, however, the swinging carriage to be swung to the rear of the machine, that is, to the right in Figs. 7, 10 and 11, the carriage 240 will be seen to take the tilted position shown in full lines in Fig. 11.

This is owin to the non-parallelism of the links 303. O viously the nearer the parallelism, the less the tilt; and the greater the divergence, the greater the tilt. This places it in the operators power to readily adjust theV tilt as desired. I

Fig. 11 also illustrates the automatic reversal of tilt when the carriage 240 is swung across to the front side of the machine with the carriage 228. In thisswin 'ng o eration the carriage 240 starts at t e ful line position shown in Fig. 11 and passes through the horizontal position shown in Fig. 10, and then to the dotted line position shown in Fig. 11. The reverse tilt there shown is at the other side.

Figs. 12 and 13 show respectively right and left shoes held in proper position with the ball ofthe shoe substantially horizontal and indicating the opposite lateral tilts of. the heel portions of the respective shoes. The lateral tilts illustrated in Figs. 12 and 13 for the shoe heels will be eected by the mechanism shown in Fig. 7, when adjusted as indicated by the diagrams, Figs. 10 and 11.

The operation of the mechanism herein described will be apparent from the foregoing description. The several hand-wheels andy other adjusting devices will be employed according to the operators judgment, so as to rapidly set the heel iping mechanism properly to the shoe. The wi er plate operating lever 280 will then be worked to elect the actual wiping. Themore complete description of the operation of. the machine as a whole, including the adjustments and shiftings of the shoe holding jacK, are suliiciently explained in sald application No. 96,748, and need not be reclted here.

It will thus be seen that I havedescribed a lasting machine or wiping mechanism embodying the novel principles of the present invention and attaining the objects and advantages thereof; and further advantages in the described structure will be apparent to those skilled in the art.
