WILLIAM C. STEWART, 0F SWAMIPSCOTT, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A. CORPORATION OF NEW JERSEY.

Application filed September 18, 1924, Serial No. 738,449, and in Great Britain May 16, 1924.

This invention relates to machines for use in the manufacture of shoes and is illus trated herein as embodied in a heel seat fitting machine.

In the manufacture of shoes to which certain types of heels are to be attached, the heel seat portions of the soles of the shoes are prepared for the attachment of heels by a trimming operation called heel seat fitting. Heels of the types referred to, of which \vood heels at the present time are by far the most important examples, are formed with concave attaching surfaces, and it is the purpose of the heel seat fitting operation to shape the heel seat portion of the sole so that the periphery of the concave attaching surface of the heel will contact closely with the adjacentshoe upper. Thus the margin of the heel seat portion of the sole is completely covered by the attached heel and is not visible in the completed shoe. The convex shape given to the heel seat of a shoe by the heel seat fitting operation is complemental to the shape of the attaching surface of a. wood heel and accordingly provides a good bearing for the heel upon the sole.

For many years this operation was invariably performed by hand. More recently machines for this purpose have been. introduced and successively used. It is an object of the present invention to provide a simplified and improved machine by the use of which heel seat fitting operations may be still further facilitated.

The stock trimmed from the heel seat portion of the sole of a shoe during the heel seat litting operation roughly of a horse shoe-shaped form, a breast cut or cuts being made transversely of the sole to receive the breast of the heel. The position of the breast cut longitudinally of the shoe and both the width and the length of the horseshoe-shaped trimming cut must, however, be varied in accordance with the size and style of the heel to be attached. Accordingly, features of the present invention comprise improved means for controlling the location of the breast cut and for controlling the form and extent of the trimming cut.

Other features of the invention comprise an improved mounting for a knife which cuts a transverse heel breast receiving flap, so as to facilitate the accurate adjustment of the knife, and devices for controlling the work including means for deflecting the heel breast receiving flap from the knife in order to reduce friction and prevent binding.

t further feature of the invention comprises an improved organization including work-supporting means by which the shoe operated upon may be properly presented to the operating instrumentalities of the machine. The illustrated work-supporting means causes the shoe to be supported with a comparatively light upward pressure during the trimming operation and to be pressed upwardly with a greater force during the making of the heel breast receiving cut, as has been found most desirable in a machine of the type herein disclosed.

Further features of the invention relate to an improved organization for operating and controlling the tool which makes the trimming cut. In order to simplify the machine and to improve its operation, as illustrated herein, a rotating cutter is mounted directly on the rotor shaft of a motor which travels with the cutter about the periphery of the heel seat portion of the sole of the shoe operated upon, and to insure that the motor shall not be left running needlessly when the machine is not operating, means is provided for cutting off the source of power from the motor when the trimming tool is moved out of operative relation to the work and for connecting the motor with the source of power when the cutter is moved toward its operative posit-ion.

lVhile' the invention is herein disclosed as embodied in a heel seat fitting machine in which ashoe is held stationary while it is operated upon by a rotary cutter moving about the periphery of the heel seat portion of the sole and by a transversely moving knife which cuts a flap at the forward extremity of the heel seat, it should be understood that this machine is primarily illustrative and that in various of its aspects the invention is not limited to a machine of this type.

With the above objects and features in view, the invention will now be described in connection with the accompanying drawings and pointed out in the claims.

In carrying out the heel seat fitting operatio'm'the illustrz ed machine is arranged to remove surplus material from the periphery of the heel seat portion of the sole of a shoe by means; of a milling cutter moved manually with respect to the suitably supported shoe undo: the guidance of an adjustaljile templet. The breast cut which is shown as inclined forwardly and downwardlv to prov Ell of the spindle n therel'or; and the U .c the short thick flap to receive the torn. ll y extending breast of a Louis heel is then made by means of a trans versely mo n g knife which enters one lateral I the sole and passes across the sole at the d )Cl inclination to its surface. In view of the variation in the styles and sizes oi heels to be applied, n'ieans are provided for adjusting the controlling templet for the '1:ovable cutter so that the work may be accurately yet speedily accomplished. Tn the preferred tor-m of the invention the zuljustmcnt is ct -"ccted by turning one or both of a pair of dialss one of which graduated to correspond with various styles of heels while the other is graduated to correspond to'various sizes of heels. in the use of the machine it is only necessary to adjust the style dial intrequentl when changing from one lot to another lot shoes, while it will be net-e... try to adj the dial as often the size 0% heel to be attached is :hanged. In general the macl'iine comprises a framework on which th is pivotally mounted a last-supporting spindle and co-operating work-positioning and supporting crease plates above said spindle so that after the lasted shoe has been mounted on the spindle, it may be swung away from the operator to bring the shoe into engagement with properly shaped movably mounted crease plates arranged to enter the rand crease of the shoe for gripping engagement therewith. A sliding table mounted above the worksupporting mechanism is provided with a vertical motor-driven spindle on the lower end of which is mounted a suitably shaped tapered milling cutter. An adjustable templet i'or controlling the path of movement of said spindle relatively to the work is provided, and after the carriage has been moved forward to present the tool in operative relation to the heel seat portion. of the shoe, the cutter spindle is moved in a horseshoe shaped path to carry the cutter around the rear of thc'heel seat portion of the sole. The tooLcarrying table is then moved out of operative position and a transversely moving knife bar is actuated to force a knife laterally through the sole from one side to the other to cut the tapered tongue which has been described above.

The frame of the illustrated machine comprises leg castings and 22 on the top of which there is supported a bed casting 24: recessed at the front at 26 to provide. ::-ooin. lor the work. The legs are held in proper spaced relation at the bottom by means of croz-nbars 28 and 30'und by means of a cross-frame 32. Work to be applied to themachine is supported prin'iarily upon a spindle or post 4.0 in which is mounted for lengthwise movement a hollow shaft ll. carrying at its upper end a tapered last pin 42 which slidably adjustable laterally. as is indicated in Fig. 12, in a manner already well understood in the art. A spring 43 housed within shaft ll tends to lift shaft 4:]. and last pin 42, such movement being limitedby a crew 45 threaded in spindle 4.0 and entering a slot 47 formed in rod 11. The spindle l is pivotally supported between cars 44- upon the crossframe by means of a bearing block 41-6 (Fig. 12) provided with trunnions pivoted in said ears. The spindle 40 is provided with a downwardly extending pin 48 which is slidable vertically it-h respect to said bearing block 46 and may be engaged by a tran -:vcrse lever 50 iulcrumed at 52 upon the cross-frame 32 when the spindle is in a substantially vertical position so as to raise it to press the work firmly into engagement with work-supporting crease plates to be later described. A spring 54 extending between the cross frame 32 and a pin upon the bearing block 46 tends to tip the spindle l0 forward and to bring itinto' accessible position for the placing of a piece of work thereon by the operator. Still. another spring 56, extending between the spindle 40 and the bearing block -16, tends to. lower said spindle when the spindle has been released by tilting forward or by the depression of the lever 50.

liltl A bed plate 60, recessed at the front to admit the heel end of a shoe, is suitably secured to the bed 2% of the machine and supports movably a pair of Work-engaging and supporting crease plates 62 (F 1, 2, and 3). These plates have the work-engaging edges thereof tapered, as indicated in l ig. 2, and by a pivotal adjustment around a center 64 (Fig. 3), which coincides substan tially with the back seam of a shoe, the plates are adapted to be brought into close engagement With the crease between the sole and the counter portion 01 the upper of a shoe. Each plate is removably secured upon a segmental plate 66, which is received Within a recess in the bed plate 60 and is provided upon its peripheral portion With a groove, best shown in Fig. 1, which receives a depending rib upon a retaining plate 68. Actuation oi these crease plates is etiectcd means of links pivotally attached to the supporting plates 66 and extending rear- Wardly therefrom through grooves in the bed plate (50, indicated by dotted lines in Fig. :3. The links 70 are pivoted at a common point by a pin 72 to the end of a linl-z 74:, which is pivotally attached at 76 to a fixed. portion olf the bed 24. A grooved track 78 is also provided upon the bed tor a transviivrsely movable block 80 sll'itted at 82 to receive the dependingend of the pivot pin 7 Actuation of this block transversely ot the machine. results in swinging the crease plates 62 graijlually but positively around the center 64 to bring them firn'ily into engagement with the shoe. lllovcment oi, the slotted block 80 may be secured by means at a bell crank 84; connected by link 86 to the upwardly extendinc' arm 88 oi an L-shaped lever 90 pivoted at 92 to in. bed 24 of the machine and provided at its torward elnlwith a handle 94- (Fig. 'i) for ear Q'enient by the operator. A pawl 96 dc signed to engage with a ratchet 98 enables the operator to lock the lever temporarily in position a'lter the crease plates have been brought into engagement with the shoe.

In order that the crease plates may not be concealed by other parts of the operating lllfl'lllil'ilHli While the work is being introduced or removed, the cutting mechanism is supported upon a sliding table adapted to be moved back so that the operator may see the ivorl: as it is positioned in the machine. The cutter-carrying table is then moved tor-- Ward into operative position and the cutter guided around; the periphery of the heel seat portion of the sole supported just above the crease plates 62. To this end the bed 2% is yn'ovided with lateral

upright portions

100 and 102 provided with horizontal tracks 10% for the support and guidance of a toolcarrying table 106 adapted to be moved forward and back in the machine by means of a hand lever 108 connected with said table:

by an arm 110 and a link 112. A suitable pawl and ratchet is provided upon this lever to hold it in its forward position as determined by a stop 11 i carried upon the lateral. member 102. The table 106 comprises a lower plate lie apertmfed at 118 l to allow movement ot' the cutter shalt with re spect iereto and an upper plate 120 spaced from the lower plate 116 and provided with a horseshoe-tilraped slot 122 (llig.

The cutter shaft is supported in perpendicular relation to the plane of this table by means of a. bearing; sleeve 124i passing through the openings 11S and 122 and provided, between

plates

116 and 120, with a disk-slniped extension 126 which lits snugly between said plates and provides a firm but readily movable bearing support for the cutter shatt, thus insuring that the cutter shaft is always maintained in perpendicular relation to the table and the Work as it is moved about. In this 124- is a cutter shaft. 130 to tl lower end of which there isse- I by a guard (not shown). The

rounded shatt 150 is directly connected to and forms an extension of the shaft of an ectric motor 136 (Fig. 1) which is supported by brackets 1.35% from a plate lit) pivoted a 142 to an i ileunediale point of a. lever let-l: which is pivoted :11 i s ear end to the upper plate h and is provided at its forth a handle 1% by means of it lay be swung to move the cutter ransa'ersely ot' the machine. The slides on hearing strips 141 and is d ar its enter 0 d and provided with ie by means of Which the plate may be swung around its pivot LE2 to move the cutter shaft ibrward and baclnvard in the machine. Current may be applied to tin actor in any suitable way, and the illustrated arrangement comprises a tlexible cord 150 leadin to a s itch box 152. The path of the en eat the switch box passes first, however, throiiig h a switch 151-, best shown in Fig. 5, which is of a Weilhnoivn type oi? construction provided With a spring-pressed phunger 156 arranged to break the circuit when the plunger is pressed in and to mill-1e the circuit when the plunger protrudes under the action ot a spring". 156 is in the path of movement of the table 106 .d is so arrangcijl that movement oi the cutter earrying table to the rear of the machine automatically breaks the circuit to the driving motor, while movement oi: the cutter-carrying table to the trout ot the machine automatically closes the circuit and starts tic motor ready for the operation of the machine in order that it may not be necessary for the operator manually to control accurately the movements of the cutter shaft as he T his plunger Hit! moves the cutter totrim away the peripheral portion of the; heel seat of the shoe, a tcmplet is provided designed to-coact with the sleeve 124 surrounding the cutter shaft so that it is merely necessary for him to cause the cutter shaft to be moved from one extremity to the other of a horseshoe-shaped slot in said templet in order accurately to perform the trimming operation. This templet comprises

plates

160 and 162 pivoted at 16tto the top plate 120 of the sliding table and provided near their forward ends with a horsxv shaped guideway or slot 166. As shown in Fig. 2 and indicated in Fig. 4, the

plates

160 and 162 are provided with an overlapping joint in order to preserve the continuity of the slot 166 as said plates are relatively adjusted and the plates are urged toward one another by means of a sprii 1.68 secured to pins projecting from thei forward ends. It will be noted that the slot 166 is provided with an enlargement or vestibule 16$) at its right forward end, and the cutter shaft moved into this vestibule at the beginning and end of the cutting operation in order that the cutter may not come into contact with the work as the table is moved into and out of its forward position until the operator is ready to start the trimming operation. The plates of the tcmplct are so located upon the moving table 106 that when the mov table is moved to its forward position, as determined by the step 114, the slot 168 occupies a predetermined position rertically above the heel seat portion of the sole of a shoe which is held by the crease plates After the trimming of the peripheral per-- tion of the heel seat has been accomplished and the ciltter-carrying table 106 has been moved to the rear, a transverse out in the sole adjacent to the breast of the heel made by means of a knife entering the sole at one edge and movable across the sole from one edge to the other substantially at right angles to the edges of the sole. This knife is positioned at a slight angle to the plane of the surface of the heel seat and is passed across the sole, until it einer "es at the other edge, to make a forwardly, dmvnwardly e):- teiiding out which forms a thick tapered flap adapted to serve as an abutment for the breast of the heel. This construction will be better understood by reference to Figs. 8 and 9 in which there is shown a woinan s shoe having an upper 350 mounted upon a last 332 and provided with a sole 35f.

Prior to its attachment to the shoe, the rear part of the sole has been split to provide a breast flap 356 of the usual form. In the operation of the machine, the, periphery of the heel seat portion 358 is trimmed of at 300 in order that the upper edge of the heel may contact closely with the upper and that the recess in the heel may fit closely over the heel seat portion. The transverse cut made eer;-

in the sole to form an inner tongue 362-is effected by means of a knife entering :one' edge of the sole and passing laterally thereby glue or otherwise, after which the cover ing flap 356 is also secured to the brcastof the heel to pro v1de a finishing cover therefor.

It will be understood that the heel ma the secured to the shoe in any one of a variety of well-known ways.

In the illustrated machine, the transverse cut is made by a knife 170 having a beveledl'ront edge 171 which does the actual cutting. l li'iifc 170 is also beveled at 173 to produce a thin edge at one side, thereby permitting movement of the knife across the sole with- This knife is ad ustably attached to and sup-- out tearing the leather of the sole.

poi-ted upon a. knife bar 172 slidable transversely of the machine and guided in a corioudingly shaped bearing provided in a iage 174. i shaped cross-section, as shown in Figs. 1 and and the cross-bar of the H is located til a slot formed in the lateral member 102 of tlbed of the machine and is capable of ustinent forward and backward to bring the knife cut at the desired point in the heel seat in accordance with the size of theheel to he applied. The carriage 174 has a lateral extension 176 serving to make the hearing for the knife bar 172 more rigid; This extension has on its lower side a threaded 1., the upper end of the bell crank lever 18d slotted for engagement with a pin 1S2 pass-iing across the end of an enlarged slot in theend of the knife bar 172, thus allowing for ad ustment of said knife bar with respect to the bell crank lever and length wis a shoe on the worksupport without fering with the proper coaction of the knife bar and the bell crank lever. At its other end the bell crank lever is connected to a rod 184: pivoted at its lower end to a rigid extension 186 (Figs. 1 and 11) of a treadle 188 pivoted at itsrear end on. the spat" rod 730 and normally maintained in upwaid position by a spring 190. Mounted This carriage is in general of upon the rod 184: and resiliently held by a spring 192 a' ainst a collar 194lan actuator 196 providedwvith a lateral extension 198 (Fig. lll slidaoly engag ng a vertical rod 200 guided in bearings 21 2 upon the crossframe 32 and provided with collar 20lfor coaction with the extension 198. The lower end of the vertical rod 2H0 is reduced at 206 and passes through a slotted end 208 of the horizontal. lever 50. By means of this arrangement the depression of the treadle ltltl not only moves the knife bar and the attached knife positively across the shoe but also lifts the spindle through the effect of the actuator 196 upon the horizontal lever 50, thus yieldingly but forcibly holdint; the work in position in the crease plates and insuring accuracy in the cutting action of the knife as it forms the breast out in the heel seat. A stop bar 210 (Fig. l) is attached to the forward end of the sliding carriage 174 in such a position that .itlimits the forward movement of the cutter shaft in its templet slot by contacting with the sleeve 124; in which said shaft is carried, so as to limit the forward extent of the trimming cut in accordance with the position of the breast cut.

Inasmuch as the effect of the actuator 196 upon the transverse lever in holding up the spindle t0 only elfective during the time that the knife is making the breast cut, other means are provided for holding up said. spindle when making the peripheral cut. These means are best illustrated in Fig. 11. from which it will be seen that the table moving, lever 108 is provided with an extension 212 connected to a vertical rod 2M surrounded by a sleeve 216 which is resiliently held against a stop collar 218 by a spring: 220. The right-hand end of the lever 50 is slotted and surrounds said sleeve 216 re ting against a shoulder 222 thereon so that when the hand lever 108 is actuated to pull the cutter-carrying table into forward. position the lever 50 is lifted resiliently to hold up the spindle so as to maintain the work in proper position with respect to the crease plates The spring 220 should be lighter than the spring 192 for the reason that it not necessary to exert as much tension in holding up the spindle during the time that the peripheral cut is being made as it necessary to exert when the trans \"rse cut being made and by reason of the dill'crences in the lengths of the lever arms involved.

The detailed construction of the connection between the knife 170 and the knife bar 172 shown particularly in. 6 and 7. Knife 170 is rigidly attached to a carrier block 230 having; a curved outer surface 232 coacti with a similarly shaped surface upon 1e knife bar 172 and clamped in position with respect thereto by means of a screw stud 23%; passing; through a slot in said knife bar, as indicated by dott ed lines in Fig. 7. To assist in the adjustment of the knife carrier 230 when screw stud is released, set screws eaa passing: through the knife bar and one" .153 the upper edge of the curved surface are provided. guard or plow 2h) is attached by screws to the knife block fill. the lower edge of said plow 24-0 being; in close relation to the lateral cutting edge of the knife 170 and the plow provided with a tapered projection 24-2 at its forward end adapted to engage under and lift up thetlap fin-med by the action of the knife to preven v interference therebetween and the knife bar 172 the cutting action progresses, Any tendency of the sole to buckle or hit away from the last during the cutting: action of the knife 170 prevented by a pressei. member coinprisine a. tapered roll 2% carried in front of the front cutting); edge 171 of the knife 170 by means of a hinged plate 2% carried upon the end of a horizontal plate 248 adjustably attached by a hinge 250 to the knife bar 172 and raised or lowered with respect to said bar by means of an adjusting screw The roll 24% is larger at the end overlying the lateral beveled edge 173 of the knife 170 which cuts more deeply into the work. Greater pressure is thus provided where it is needed. A spring: 254: passing between the vertical hinged plate 24:6 and the knife bar 172 normally holds the carrier for said tapered roll 244lin a vertical position determined by a stop 247 2) extending; out from the end. of the knife bar 172 engage with the back side of said plate when the knife bar is moving forward the rearward movement of the knife bar, howeveu the sprinpj254t allows the roll can rier 24:6 to be lifted, thus avoiding possible damage to the shoe. I

As has been stated in an early part of this specification, variations in styles and sizes of wood heels, which means variations in both their widths and lengths, render necessary some means for varying the position of the breast cut for varying the extent of the peripheral or trirniniin; out and for do termining; the adjustment of the templet controlling the width or spread of the horseshoe-shaped path through which the trimming cutter moves. To these ends mechanisms are provided whereby the elements of the machine may be adjusted to compensate for variations in the styles of heels and other adjustments made to compensate for variations in the sizes of heels of a given style. lnasmuch as the adjustments for the sir Le of the heel must be made most frequently, a conveniently located manually operated size dial. 260 (Figs. 1, 2 and 10) is provided near the front left-hand side of the machine, and this dial, which is gradu- During llll) ated in accordance with the scale of sizes usedfor wood heels, may be set with referenceto a pointer 262 (Fig. 10) mounted upon a bracket 264extending out from the frameof the machine with very slighteifort upon thepartof theoperator so that

templets

160, 162, which control the spreadof the path of the trimming'cutter may be adjusted to control the width to which the heelv seat of a sole is. trimmed. Since the gr-aduations-of the size dial :correspond to the'widt-hs of the different sizes of =heelsiof aigiven style, the setting oflhesize dial per mitshthe trimming of the heel seat to a width corresponding to that ofthe size of heel for which the size-dial260 is set. The setting of the size dial- 260 also controls the extent 'of the trimming but lengthwise of the shoemnditheposition of the breastv cut through connections hereinafter described.

HSince the relation offhe length to the \VltltllOfvllGBlS of" the same nominal sizebut' ofditfer-entstyles varies,'mechanism is also providedfor changing the-extent lengthwiseofthe shoe of the trimming: cutand :theposition of the breast cut relatively to the widthlo whichtheheel seat is trimmed. This isdone by-ineehanism arranged to adjust the-carriage 1-74 forward or backward.

The carriage 174,- it" will be remembered. carries theiknife bar 172 and-the dimitmg stop bar 210 so that the position of the-carriage 174 controls both the-forward extent of the trimming cut and the-fposition of' the breast cut. .Theinechanism: for effectingthis movement of carriage :17-1 is controlled by a graduated. style dial .266 located at. the

rear of the size dial 260. A fixedp'ointer 268 is positioned adjacent to the style dial 266 :towprovide a pointmof reference with respect to which that .dial may be set. .The relationof the graduationson the styledial to the various heels which are tobe attached to the shoes vtobe operated uponis deter- I mined at the start and azchart setting forth the proper setting of the style dial 266 for eachofnt-he various styles of .heelsin use in thefactorymay be prepared and-postedin a convenient place. The style .dial :266 is held in position frictionally by means of a screw270 (Fig. liengaging a tubular extension .of the dialand' is provided with a stop pin 27 2 adapted to engage a coacting pin274in the bracket 264 to limit the movement'of. the dialto something less than one complete revolution. :A similar stop pm- 284 is a cam 288. A:bar-292(Figs. 2and4) is supported upon the parallel arms of bell crank levers-294 and 296 carried in brackets on the frame member 102 for parallel movement transversely of the machine. ported upon'the other arms of the bell crank levers 294 and 296 is a. bar 300 having a roll 200 mounted on and depending from its lower surface and positioned in the track of cam 288. The upper surface of bar 3001s grooved at 302 to receive and control the movements-of a roll 30% depending from one arm of a bell crank lever 306(Figs. 1 andl) pivotally attached at 308 to abracket 310 secured to the upperface of-the table 106. 'lhe movements of thisbell crank lever 306 are made effective to openorclosethe templet plates 160, 162-byconnecting the other arm of said lever to one end of a lever 312 (Fig. fulcrumed at 31Lon the table 106 tenlplet slot. It will be noted that the connection between the bell crank 306 and the lever-312 isprovided by means of a stud 324:

(Fig. l) which may be adjustably positioned with respect to the bell crank -306ain an enlarged opening 326. It will also=be noted that, by reasonzof the groove 302 in the bar 300, the adjustment of the-templet plates is not disturbed by forward and-backward movement of the cutter-carryingv table 106 with respect to the cam'control'led

parallel bars

292 and 300.

The mechanism hereinbefore referred to for changing the relation of the position of templets160, 162 to the position of carriage 17 i and, accordingly, -for-contr0lling the relation of the width to which ithe heel-seat is trimmed to the forward extent'of the trimming cut and the position of the breast cut, so asto adapt the machine to opcrate on heelshof different styles, will now be described. ffMechanism. for l effecting this adjustment best shown in Figs. 1. and 10 from which it will be seen that the horizontal shaft 280' is externallythreaded with a screw thread of long pitch which is in threaded engagement with the interior of a tubular extension or sleeve 330 forming part of the style dialv266. The extension 330 is also externally threaded to screw in theinterior of the sleeve 178 upon the lower face of the lateral extension 176 of the carriage 17 1-.

Referring now to Fig. 10, when the size dial alone is rotated, the spread of templets 160,162 is changed by reason of the connections operated by the rotation of shaft 280. The engagement of-sleeve 330, carried by the till constructed and arranged to vary the path of the cutterin accordance with the setting of the dial so as to trim the heel seat to iitthe particular size 01 heel indicated by the dial.
