'76 Claims.

This invention relates to lasting machines and more particularly to shoe-end-lasting machines. It is herein illustrated as embodied in a machine for lasting the heel ends of shoes, although it will be recognized that in its more general aspects it is not limited to heel-end-lasting machines. The machine herein shown is provided with end-lasting means comprising wipers and means for operating them to wipe the margin of the upper around the heel end of the shoe inwardly over a sole a plurality of times and with means for thereafter driving fastenings to fasten the upper to the margin of the sole,

In accordance with one important feature of the invention novel means is provided for positioning and controlling a shoe in its relation to end-lasting means. For the purpose in View there provided, as herein illustrated, means for imparting to the shoe a yieldingly effected movement to position it in predetermined relation to the lasting means and for thereafter imparting to it in the lasting operation positive movements or automatically determined extent in the san'ie direction as said yieldingly effected movement to press i against the wipers. The

construction herein shown comprises a shoe-supporting member movable in directions heightise of the shoe and operating means therefor arranged to move the supporting member to press the shoe yieldingly against a holddown and thereafter to impart to i" repeated positive movements to press the-shoe against the wipers in time relation to successive wiping movements of the wipers, the construction being also such as to permit retractive movement of the supporting member to relax the pressure between the successive wiping movements. More particularly, as illustrated, there is provided means for effecting automatically a. positive connection between said operating means and the shoe-supporting member after the yieldingly effected movement of the supporting member has been completed and for maintaining said positive connection thereafter in the movements of the opcrating means to press the shoe against the wipers and to relax the pressure.

Another feature of the invention consists in novel means for determining the heightwise position of the shoe relatively to the means for lay- 5!) ing the shoe upper over the bottom of the shoe, the con truction shown comprising a holddown arranged the path of movement of the overmeans for determining the heightwise position of the shoe by engagement with a portion of themargin of the upper overlying the sole.

As shown the holddown is mounted for movements in directions heightwise of the shoe and means provided for limiting such movement in one direction to cause the holddown to serve as positive means to determine the heightwise position of the shoe. Preferably and as illustrated, the holddown is mounted for movement also away from the margin of the shoe upper in the wiping operation by engagement of the wipers therewith, and is so guided in this movement as to relax its pressure on the shoe and thus permit the shoe to be pressed more forcibly against the wipers, as hereinbefore explained, in time relation to the operations of the wipers.

As a further feature, the invention provides a novel organization including fastening-inserting means of the multiple or gang type, the construction shown comprising a plurality of fastening-inserting devices so controlled as to maintain an unvarying relation to one another during the operation of the overlaying means and yet relatively adjustable for shoes of different sizes. As illustrated, there is provided means for adjusting laterally of the shoe the fastening devices that insert fastenings at the opposite sides of the heel seat to position the fastenings in predeter ined relation to the edge of the shoe bottom, and such provision for adjustment is combined with means for determining the relative positions of the devices in accordance with the size of the 5 shoe being operated upon.

The above and other features of the invention, including also improvements in shoe-end-clamping means and various novel details of construction and combinations of parts, will now be more particularly set forth by reference to the accompanying drawings and will be pointed out in the claims.

The illustrated machine is in many respects similar to the machine shown and described-in Letters Patent of the United States No. 1,700,970, ranted February 5, 1929, on an application of 7 William C.,Baxter, for shaping the heel-end portion of shoe upper materials over a form and securing them to an insole, which Letters. Patent may be consulted for a better understanding of certain details not hereinafter fully described.

The machine herein shown is provided with twin mechanisms for operating on right and left shoes and, as in the machine of the Letters Patent above referred to, separate clutch means are provided for connecting each of the twin mechanisms to power driving means so that either mechanism g with means for securing it in lasted position by operations.

heel-end embracing band and a shoe-supporting tacks, together with means for supporting and positioning the shoe for the wiping and tacking The positioning means includes a jack which is moved rearwardly to force the heel end of the shoe into. the band and through which a heightwise movement also is imparted to the shoe to press it yieldingly against a holddown arranged to determine the heightwise position of the shoe prior to the lasting operation. Thereafter positive movements of automatically determined extent are imparted to the shoe in the same direction as the yieldlngly effected movement to press the shoe firmly against the wipers, as more particularly hereinafter described. These twin mechanisms, except as modified for the treatment of rights and lefts, are similar in construction and mode of operation so that a description of one will be sufficient for both.

The illustrated machine is provided with a base 20 (Fig. 2) comprising side members 22, cross ties 24 and a top or table portion 26.- Extending between the. side members 22 is the main driving shaft 28 which may be driven from any suitable source of power as, for example, an electric motor 30. Preferably, the main driving shaft 28 is continuously driven and is connected to each of the twin mechanisms of the machine by separate clutch means so that either mechanism may be operated independently of the other at the will of the workman. As shown in Fig. 2, the main driving shaft 28 has secured thereto a gear 32 which is operatively connected to a gear 34 fast upon a driven shaft 36. The shaft 36 is mounted in suitable bearings carried by the base 20 and extends from front to rear substantially midway between the side members 22. Secured to the driven shaft 36 is a worm 38 the teeth of which mesh with the teeth of l a worm wheel 49 loosely mounted upon a fixed shaft 42 which extends between the side members 22. The worm wheel 40 is provided with enlarged hub portions between which and a pair of sleeves 45 also loosely mounted upon the shaft 42, one at each side of the hub portions of the Worm wheel 40, there are provided separate clutches 44 which may be of any usual type such, for example, as that shown in the above-men tioned Letters Patent, for connecting the sleeves 46 to the hub portions of the worm wheel 40. Each of the clutches 44 is normally held disconnected from the hub of the worm wheel 40- by a clutch-disengaging member 48 (Fig. 2) mounted for rocking movement upon a support 50. The member 48 is provided with a downwardly extending arm 52 which is normally under the influence of a spring 54 tending to hold the member 48 in engagement with a shoulder 56 formed upon the clutch 44 and thus to maintain the associated sleeve 46 at rest. Each of the members 48 is connected to a treadle 58 in the same manner as in the machine of the Letters Patent above referred to, the construction and arrangement of the parts being such that after the treadle 58 has been depressed to move the member 48 out of engagement with the shoulder 56 to permit the clutching of the sleeve 46' to the worm wheel 40, the member 48 is moved back into position for engagement with the shoulder 56' without further attention on the part of the workman and regardless of the position of the treadle so that the machine will come torest after making one cycle of its operations.

Each of the sleeves 45 has mounted thereon cams for eifecting movements of the operating parts through trains of mechanism later to be described.

The heel-end clamping means herein shown is in many of its features similar to the clamping means shown and described in the abovementioned Letters Patent. To receive and embrace the heel end of the shoe there is provided an endeeinbracing band comprising an inner form 59 of leather or other suitable materi'al which is mounted upon supports or holders hereinafter described to which pressure is applied to close the band about the end of the.

shoe upper and subject the upper to shaping pressure. Mounted for reciprocating moverent on ways formed in the frame or table 26, Fig. 5, is a slide or end band operating crosshead 62 having connected therewith one member 64 of a toggle the other member 66 of which is pivotally connected at 66 to a stud '76 secured to the frame 26. The toggle members .64, 66 are connected to an actuator for reciprocating the head 62 by straightening or breaking the

toggle members

64, 66. As illustrated, the toggle members are connected at '72 to a link '74 pivoted at T6 to an arm '78 mounted for rocking movement on a fixed shaft 80. Extending from the arm '23 is an operating rod 82 the lower end of which is pivotally connected at 84 to an arm 86 mounted for rocking movement on a supporting rod 88 which extends between the sides of the machine. The arm 86 carries a pin or roll which rides in a cam groove 90 formed in the face of a cam carrier 92 carried by the sleeve 46, the construction being such that upon rotation of the sleeve 46 and the cam carrier 92 the toggle will be operated to effect reciprocation of the operating head 62.

The supports or holders of the heel-end embracing band comprise side members 94 and corner members 96 flexibly joined together by links 96, Fig. 4. The corner members 96 are pivoted at 100 to a T-shaped rear member or block 102 carrying a rearwardly extending pin 104 which passes loosely through an opening in the operating head 62. The block 102 is held against rearward movement by a plate 166 which engages a shoulder 163 formed upon the block. The plate 166 is secured to the frame member 26 by screws upon the upper ends of which are mounted sleeves 112 arranged to bear at opposite sides against the rearwardly extending portion 114 of the block 102 to prevent movement of the block transversely of the machine. To close the side and

corner members

94, 96 of the band yieldingly about the end of the shoe as the head 62 is advanced, trains of mechanism connect the opposite ends of each of the side members 94 and the forward ends of the corner members 96 to the head 62. In the contween the head head 62 by yielding struction shown, these trains of mechanism comprise toggles positioned at the opposite ends of each of the side members and operated through connections to the head, and yieldable links beand the forward ends of the corner members. Since the mechanisms for connecting the

members

94, 96 to the head 62 are the same upon opposite sides of the end band, a description of one will suffice for both. Each of the corner members 96 is connected to the

links

132, 134 one of which, 132, is pivotally connected to the'member 96 at 136 and the other one of which is connected to the head 62 by a lost motion connection comprising a pin 138 carried by the head 62 which projects into a slot 146 formed in the link 134. The

links

132, 134 are similar in construction to corresponding parts shown and described in Letters Patent of the United States No. 1,726,333, granted September 3, 1929 on an application of E. A. Holmgren.

Pivctally connected to the forward end portion of each side member 94 is one member 116 of a to the other member 126 of which is con- J nectecl at 122 to a yielding abutment 124. A link 126 connects the joint of the toggle with the head 62, the construction being such that as the head 62 is advanced, Fig. 4, the toggle will be straightened more or less and the forward end of the side member 94 will be moved inwardly. The abutment 124 is slidably mounted in the frame 26 and has a reduced outer end portion which passes through an opening in an adjustable cap 128 between which and a shoulder formed on the abutment 124 is a spring 130 which normally acts to force the abutment inwardly. For applying additional pressure to the rear corners of the band there are provided toggles positioned at the rear ends of the side members and arranged as the head is advanced to apply pressure to the corners of the band in directions substantially normal to the lateral surface of the last. Pivotally connected to the rear end portion of each of the side members 94 is one memb r 148 of a toggle the other member 150 of which is pivotally connected to an adjustable abutment 152. The abutment 152 is slidably mounted in the frame 26 and has threaded therein a rod 154 which extends through an opening in a sleeve 156 threaded into the frame 26. The sleeve 156 is counterbored to provide a seat for a collar 158 secured to the rod 154 and between which and a lock nut 160 threaded upon the outer end of the rod 154 there is provided a washer 162 also threaded into the frame member 26. It will be readily seen that by turning the rod 154 the abutment 152 may be adjusted to vary the initial positions of the

toggle members

146, 160 and the initial position of the rear end of the side member 94. The toggle mem bers 148, 156 are moved into a more or less straightened position to apply inwardly directed pressure to the corners of the band through a yielding connection beJween one member of the toggle and the yieldable links 132, 1 -4 comprising a spring 164 surrounding a rod 166 and bearing at one end against a shoulder 163 formed on the rod 166 and at the other end against a swivel block 1'10 pivoted at 1'72 to the toggle member 143. The rod 166 is pivoted at 1'74 to a laterally extending lug formed on the link 134 and extends through an opening in the block 170 and has threaded upon its outer end portion a pair of nuts 176.

From the above description it will be readily seen that as forward movement is imparted to the H head 62, band-closing pressure is applied to the

members

94, 96 through the toggles and links, the lost motion connection being the

links

132, 134 and the head 62 permitting the toggles 118, 120 to swing the forward ends of the side members 94 inwardly toward the sides of the shoe to cause the band to conform substantially to the shape of the heel end of the last before pressure is applied at the corners and around the end of the band. In order to limit swingfng movement 1' of the corner members 96 as the band is ex panded during rearward movement of the crosshead the block 162 is provided with a pair of forwardly extending abutments 116 arranged to engage the forward ends of the corner members 96. I

The illustrated machine is provided with end wipers 186 (Figs. 4 and 22) for laying the margin of the heel end of the upper inwardly over the sole after the end portion of the upper has been clamped between the last and the heel band. As I -3;

shown, wiper-carrying plates 182 are each provided with guiding slots 184 in which are rolls 166 mounted on pins extending downwardly from or secured to a wiper-covering plate 188. The wipers are provided with tongues 131 which extend into grooves 183 formed in members 185 secured to the carrier plates 182, Fig. 24. The wipers are secured to the carrier plates 182 by bolts 190 which extend through slots 185 formed in rearwardly extending portions 187 of the wipers and by spring-pressed latches 192 which enter slots 189 formed in the wipers. The plates 182 are provided with pins 191 for depressing the latches 192 to permit removal of the wipers, Fig. 23. The plates 182 are further guided in their swinging movements by a curved tongue 193 which, as shown, is carried by one of the plates and extends into a curved groove 195 formed in the other plate, the plates thus being interlocked as shown for swinging movement about the axis of the curved groove 195. The wipers 180 are provided with

openings

194, 196 through which tacks are driven to secure the overworked edge portion of the upper to the insole as will more fully appear, the openings 196 along the sides of the wipers being sufficiently elongated to permit the fastenings to be inserted different distances from the edge ofthe shoe bottom.

Each of the carrier plates 182 is connected by a link 198 to a slide 200, Fig. 4, mounted for reciprocating movement in the top frame or table 26. The slide 260 is reciprocated by a train of mechanism which preferably includes a toggle at each side of the end band operating toggle. Connected to the slide 260 at each side is a toggle member 202, the companion toggle member 204 being pivotally connected at 206 to an adjustable thrust member 208. Pivotally connected to the

toggle members

202, 264 at 210 is an actuator for straightening and breaking the toggle comprising l'nks 212 connected at 214 to a swinging frame 216 which is fulcrumed upon the fixed shaft 80. The frame 216 is connected by a link 218 to an arm 220, Fig. 5, which is mounted for rocking movement on the support 88. The arm 220 has extending therefrom a pin or roll 222 which rides in a wiper cam path 224 formed in one face of the carrier 92, the construction being such that upon rotation of the carrier the wipers will be caused to close and open. The cam path 224 is formed with a number of wiper actuating portions as indicated in Fig. 5 so that successive wiping movements are imparted to the wipers 180 during each rotation of the cam carrier 92.

For supporting the shoe there is provided a support or jack shown particularly in Figs. 6 and 7. The heel end of the shoe is supported by a member 234 the upper surface of which is formed and arranged to engage the top of the cone of the last, as clearly shown in Fig. 6. Extending upwardly from the member 234 is a pin 230 which enters the last pin hole in the last. The member 234 is mounted for swinging movement about an axis extending heightwise of the shoe and located forwardly of the heel pin so that the heel end of the shoe may be centralized within the end band in response to pressure of the band on the opposite sides of the heel end of the shoe. As shown, the member 234 is pivotally connected at 236 to the forwardly extending arm 238 of a bracket 240 mounted upon the upper end of a rod 242. The pivot 236 is located forwardly of the heel pin, substantially opposite the top of the forepart of the shoe. The heel-supporting memher 234 is normally held yieldingly against swinging movement about its pivot 286 by a pair of equalizing springs 235 secured to the bracket 240 at 237 and bearing at opposite sides against the member 234. In order that the pressure of the wipers 180 on opposite sides of the heel end of the shoe will be equalized as the wipers move inward 1y over the heel seat during the overlaying operation, the heel pin 230 is provided with a ballshaped upper end 232 to permit the shoe to rock laterally on the supporting member 234.

The rod 242 is slidably mounted in a bearing in the upper end of a carrier 246 pivotally connected at 248 to the frame 20 of the machine. Between the upper surface of the carrier 246 and the bracket 240 there is clamped to the rod 242 a bracket 250 for supporting a rest 252 for the toe end of the shoe. The bracket 250 is provided with a forwardly-extending arm 254 to which is pivoted at 256 a forwardly-extending member 258. The member 258 is provided with an arcuate slot 260 concentric with the pivot 256 and through which extends a binding screw 262 threaded into the arm 254 of the bracket 250 and arranged to hold the arm 258 in adjusted position. The toe end of the shoe rests upon a pad of leather or other suitable material with which the upper surface of the toe rest is provided, and extending upwardly from the toe rest at opposite sides thereof are arms 266 loosely mounted upon pins 264 and arranged to engage the opposite sides of the shoe to prevent ,t

lateral displacement of the toe end of the shoe relatively to the toe rest 252. The arms 266 are urged toward each other by torsion springs 268 and are provided with intermeshing gear segments 270 at their inner ends, Fig. 3. The toe rest 252 is supported by a bracket 272 (Fig. 7) slidably mounted upon the member 258. The bracket 272 is preferably formed of two principal parts one of these parts 274 being provided with a guideway through which extends the member 256 and the other part 276 being provided with a split bearing 277 in which is mounted the downwardly-extending shank portion 278 of the toe rest 252, Fig. 12. The

parts

274, 276 of the bracket 272 are pivotally connected together at 280 and are provided with a screw-and-slot connection 282 for holding the parts against movement relatively to each other from adjusted position. Thus it will be seen that the toe rest 252 may be adjusted heightwise relatively to the bracket 272 in accordance with the spring of the last or rotated about a vertical axis to position the arms 266 forengagement with the shoe at opposite sides of the tip line regardless of the swing of the toe end of the last. Conveniently also, the toe rest 252 may be adjusted about a horizontal axis by swinging the part 276 of the bracket 272 about its pivot 280 so that the toe rest may have a substantially straight line engagement with the toe end of the shoe at and near the tip line thereof.

The shoe support is provided with means for adjusting the toe rest toward and from the heelsupporting member to accommodate shoes of different lengths. As shown, the bracket 272 is provided with a short laterally-extending shaft 284,

Fig. 7, to which is secured a pinion 286, Fig. 6, the teeth of which mesh with the teeth of a rack 288 formed upon the member 258. Secured to the outer end portion of the shaft 284 is a hand wheel 290 for rotating the pinion 286 to impart longitudinal movement to the bracket 272 and the toe rest 252. The bracket 274 is provided with a somber 293 adapted to cooperate with a scale 292 on the hand wheel 290 to indicate the proper position of the hand wheel and the corresponding size positions of the toe rest relatively to the heel support.

The heightwise position of the shoe-supporting jack rod 242 may be adjusted relatively to the carrier 246 by means of a vertically adjustable screw 294 which engages the lower end of the rod 242 and is threaded into the lower portion of a sleeve 296 slidably mounted in the carrier 246. The sleeve 296 is provided with a pair of spaced downwardly-extending arms 298 between which at their lower ends is pivoted the head 366 of a supporting member or bar 302 slidably mounted in bearings 304 formed in a bracket 306, the head 300 having a rearwardly-extending portion 368. The rearwardly-extending portion 308 of the head 300 is provided with a seat for a spring 310 which extends downwardly in a bore 312 formed in the bracket 306 and bears at its lower end against a washer 314 resting upon a set screw 316 which is held in adjusted position in the bracket 306 by a lock nut 318.

The rearward swinging movement of the carrier 246 about its pivot 248 to force the heel end of the shoe carried by the jack into the heel band is effected by means of a cam 320 formed in one face of a cam carrier 321 secured to the sleeve 46. The connections between the cam 320 and the carrier 246 comprise a lever 322 fulcrurned upon a laterally-extending shaft 324 mounted in suitable bearings in the base 20 of the machine and a link 326 yieldingly connected to the carrier 246 by a spring 328. At one end the spring 323 is connected at 330 (Fig. 11) to the link 326 and at its other end the spring is connected to a block 332 pivotally connected at 334 to the carrier 246. A reduced end portion 336 of the link 326 passes through an opening in the block 332 and has fast upon its outer end a collar The configuration of the cam 320 is such that when 1 the machine is treadled to start one of the twin mechanisms into operation the shoe-supporting jack will be moved rearwardly into operative relation to the heel-end embracing band and the end wipers and held there during the operation of the machine, after which the jack will be moved outwardly into inoperative position. It will be understood that through the spring 328 the heel end of the shoe is thus forced yieldingly into the heel band.

The illustrated machine is provided with lock- I ing means, Figs. 2 and 5, for holding the jack against forward movement during the lasting operations. Pivotally connected to a bracket 340 mounted for swinging movement upon the fixed shaft are pawls 342. The pawls 342 are urged in a counterclockwise direction, as viewed in Fig. 5, by springs 344 the movement of the pawls in that direction being limited by shoulders 346. The pawls 342 are arranged in staggered relation for engagement with teeth 348 formed upon I members 350 secured one at each side to the carrier 246. As the carrier 246 is moved rearwardly the pawls 342 yieldingly engage the teeth 348, after which the bracket 340 is swung in a counterclockwise direction, Fig. 5, to lock the pawls positively in engagement with the teeth so as to prevent retrograde movement of the carrier during the operation of lasting the heel end of the shoe. "he bracket 343 has a downwardly-extending arm 352 connected by a link 354 to the upwardlyextending arm of a bell-crank lever 356 ful'crurned at 358 to the machine frame 20. The lever 356 has a rearwardly-extending arm 360 carrying a pin or roll 362 which rides in a cam path 364 formed in the face portion of a cam carrier 366 mounted upon the sleeve 45, the construction being such that after the carrier 246 has been moved rearwardly to position the shoe in operative relation to the end band and the wipers, the bracket 340 is swung in a counter-clockwise direction to lock the pawls 342 in engagement with the teeth 348, as above described, during the heel* end lasting operation, after which the bracket is swung in a clockwise direction to move the pawls 342 out of engagement with the teeth 348 to permit the jack to be swung into its outer or inoperative position.

After the heel end of the shoe has been moved into the heel band by rearward movement of the carrier 246, cam controlled means are provided for imparting a yielding upward movement to the bar 362 and the rod 242 to force the heel end i the shoe into engagement with a holddown arranged to determine the heightwise position of the shoe relatively to the wipers 180, after which positive heightwise movements are imparted'to the shoe in time relation to the movement of the wipers to increase the pressure of the wipers on the upper materials.

As illustrated particularly in Figs. 1, 2 and 5, a holddown support or bracket 363 is secured to a shaft 365 which is mounted for rocking movement in bearings 368 carried by the table or frame member 26. The bracket 363 is provided with an inclined guideway 369 for a holddown 3'70 provided with a downwardly extending finger 372 arranged to engage at the extreme rear end of the shoe the inturned portion of the shoe upper which has been previously secured to the insole by means of an assembling tack, Figs. 16, 1'7 and 18. The holddown 370 is urged downwardly and rearwardly in the guideway 369 by a spring 374 which bears at one end against a shoulder 376 formed on the holddown and at the other end against a plate 3'78 arranged to close one end of the guideway. The spring 3'74 surrounds a rod 336 which is threaded into the holddown 376 and extends forwardly through an opening in the plate 378. The rod 38:) is provided with a square head for purposes of adjustment and with a pair of locking nuts 382 for holding the holddown 370 in adjusted position within the guideway.

Fast to the right-hand end of the shaft 365, Figs. 1 and 2, is a bracket 384 having a downwardly extending arm 386 carrying a springpressed plunger 338 and an adjustable stop screw 396 and a forwardly extending arm 392 carrying an adjustable stop screw 394. As shown in Fig; 2 the spring-pressed plunger 388 bears against the front face of the table 26 and urges the bracket 384 and likewise the holddown support or bracket 363 in a clockwise direction until the end of the screw 334 engages the top face of the table 26. The screw 394 may be adjusted so that the downwardly extending finger 372 of the holddown 376 will first engage the heel seat of the shoe below the plane of operation of the end wipers 180. After the heel seat of the shoe is brought into engagement with the finger 372 in the upward movement of the shoe, the holddown 3'70 and the bracket 363 move upwardly with the shoe, thus rocking the shaft 365 and the bracket 334 in a counterclockwise direction to compress the spring plunger 388 until the screw 390 engages the front face of the table 26. The upward movement of the shoe is thus yieldingly retarded, and this tends to avoid any objectionable shock in the jacking of the shoe. It will be readily seen that by adjustment of the screw 390 the heightwise position of the heel seat relatively to the wipers may be accurately determined.

Fulcrumed at 396 to the bracket 306, Fig. 6, is a lever 393 mounted for rocking movement on the shaft 324 and provided with a roll 400 arranged to bear against the periphery of a cam 402 carried by the sleeve 46. The bracket 306 is provided with an upwardly extending portion 404 the upper end of which is shaped to overlie the rearwardly extending portion 308 of the head 300. For holding the roll 400 against the cam 402 there is provided a spring 406 between the portion 404 of the bracket 306 and the carrier 246. The spring 406 extends upwardly in a bore in the carrier 246 and bears at its upper end against a washer and set screw 408, and at its lower end the spring surrounds the upwardly extending shank portion 410 of a T-shaped member the head 412 of which is seated in the upper surface of the bracket 306. Surrounding the downwardly extending bar 302 below the head 300 is a sleeve 414 having a pair of forwardly extending ears 416, Fig. 8, between which is pivoted upon a laterally extending pin 418 a locking lever 420. At its outer end the locking lever is pivotally connected to a pair of downwardly extending links 422 pivoted at 424 to the bracket 306. Pivoted at 426 to the carrier 246 is a bell-crank lever 428 having an upwardly extending arm 430 the upper end of which is forked around a rod 432 threaded into the carrier 246 and a pair of forwardly extending arms 434 provided with slots 436 into which extend the opposite ends of the pin 418. The bell-crank lever 428 is urged in a clockwise direction by a spring 438 which surrounds the rod 432 between the forked upper end of the arm 430 and a pair of lock nuts 440 threaded upon the outer end of the rod. Clockwise movement of the lever 428 under the influence of the spring 438 is limited by engagement of a screw 442 threaded into the median portion of the arm 430 with the front face of the carrier 246.

The configuration of the cam 402 is such that after the carrier 246 has completed its rearward movement the lever 398 is swung in a clockwise direction, as viewed in Fig. 6, elevating the bracket 306, which serves as an operating member for the bar 302 and the parts supported thereby, and through the spring 312 imparting a yielding heightwise movement to the bar 302 and the rod 242 to move the shoe into engagement with the holddown 370 and to raise the holddown to the limit of its movement so as to position the heel seat of the shoe in predetermined heightwise relation to the end wipers 130. As the lever 398 is thus swung in a clockwise direction the locking lever 420 through the links 422 is swung also in a clockwise direction from the position shown in Fig. 6 to the position shown in Fig. 10. As shown in Fig. 10, the locking lever 420 is provided with a cam surface 444 which, as the lever 420 is swung into the position shown in Fig. 10, bears against a surface 446 formed on the bar 302, thus locking the bar and the operating member or bracket 306 against relative movement. Preferably, the movement of the lever 420 into position to lock the bar 302 and the bracket 306 together is not completed until after the shoe has a completed its yielding heightwise movement. For

this purpose the heightwise position of the sleeve 414 and the horizontal pivot pin 418 may be adjusted by movement of the screw 442 to vary the time when the lever 420 arrives in locking position. At this time a dwell is preferably formed in the cam 402 to maintain the shoe stationary during the closing of the heel band and while the wipers 180 begin their first advancing and closing movement to gather the margin of the shoe upper materials and wipe them inwardly over the edge of the shoe bottom. During further inward movement of the wipers 180 to complete their first closing movement, the lever 398 is rocked still farther in a clockwise direction, as viewed in Fi 6, by the cam 402, thereby imparting to the bar 302 and the rod 242 through the locking device a positive heightwise movement to raise the shoe and cause the inturned portion of the shoe upper materials to be subjected to increased pressure between the sole and the end wipers. In this operation the bell-crank lever 428 is swung against resistance of the spring 4 8 by the raising of the sleeve 414. This movement of the shoe is permitted by reason of the fact that the holddown 370 is moved inwardly away from the margin of the shoe bottom by engagement of the wipers 180 therewith during their inward movement, as clearly shown in Figs. 1? and 18. The holddown is thus pushed inwardly from over the margin of the upper and a portion thereof is forced up the inclined guideway 363, thus relieving the pressure on the shoe bottom and permitting the shoe to be forced farther upwardly as described, although the holddown is still maintained in contact with the shoe and is pressed down upon the sole after its movement from over the upper by the spring-controlled plunger 388. As the wipers are thereafter retracted, the shoe support member or bar 302 is lowered to relieve the pressure of the shoe against the wipers. For this purpose the cam 402 is suitably shaped to permit a counterclockwise movement of the lever 398 and a corresponding downward movement of the member 306 under the influence of the spring 406. As this downward movement of the member 306 occurs it is still locked to the bar 302 by the locking device, the bell-crank lever 428 being swung idly in a clockwise direction by the spring 438. The extent of the downward movement of the bar 302 is therefore positively determined, although the downward movement is actually effected by the spring 406. As the wipers are again closed inwardly over the shoe bottom the earn 402 acts a second time to raise the shoe support member 302 positively through the locking device, this movement being a movement of greater extent than the first positive movement to increase still further the pressure of the wipers on the upper in the second overwiping operation. Thereafter, while the shoe is held positively supported, tacks are driven as hereinafter described to fasten the margin of the upper to the sole. In the return of the parts to starting positions, the member 306 is still locked to the bar 302 until the movement of the bell-crank lever 428 is stopped by the screw 448, after which further downward movement of the member 306 acts through the links 422 to swing the locking member 420 into position to release the bar 302.

It will be evident that by adjusting the screw 448 the position of the sleeve 414 along the bar 302 may be varied. the effect of which will be to vary the time in the movement of the lever 398 when the member 420 becomes operative to grip the bar 302. It is contemplated that after the proper adjustment has been made it will ordinarily be unnecessary to change the adjustment in operating on shoes of different sizes. As different-sized shoes are operated upon the spring 312 will be variably compressed in forcing the bottoms of the shoes against the holddown, but the locking of the member 306 to the bar 302 will occur each time just as the lever 398 completes its first operating movement. Accordingly, positive movements of invariable extent regardless of the size of the shoe will be imparted to the bar 302 to press the different-sized shoes against the wipers.

For secuJing the margin of the upper in lasted position on the heel seat of the shoe there is pro vided in each half of the twin machine fastening mechanism of the gang tacker type which is in many respects similar to the fastening mechanism disclosed. in the previously-mentioned Letters Patent. Each of the fastening mechanisms is mounted upon a support 450, Figs. 1 and 2, which extends transversely of the machine frame above the table 26. The support 450 is carried by side rods 452, one on each side of the machine, and is secured to the upper end portions of the rods 452 as indicated in Fig. 1. Each fastening mechanism is located. in predetermined relation to its associated upper-shaping means by a positioning pin 454, Fig. 2, which extends from the frame 455 of the fastening mechanism into a locking recess 456 formed in the table 26, Fig. 2.

In the construction shown each fastening mechanism comprises a rear or end tacker device, Fig. 2, arranged to insert tacks at the rear end of the shoe and two side tacker devices each arranged to insert seven tacks aiong th side of the heel seat. Each of the rear and side tacker devices is connected to a drivin plate 458 by a driver bar 460, and each driver bar has secured thereto an appropriate number of tack drivers 462 for driving tacks through tack nozzles or tack holders 464, Fig. 13. The driving plate is guided in its up and down or driving and retracting movements by guide sleeves 466 which slide upon guide rods 46% secured at their lower ends to the frame of the fastening mechanism. Pivot-ally conn cted to each of the driving plates 458 at 4'70 is a tacker arm 472 the rear end of which isconnected to a link (not shown) pivoted to the frame 455 of the fastening mechanism.

The tacks are fed to the nozzles 464 through a series of conduits 478, Fig. 2, which are supplied from. a distributing or separating mechanism 480 to which tacks are delivered from a hopper 482 substantially as in the machine disclosed in he previously-mentioned Letters Patent. The means for operating the hopper 432 and for separating and delivering the tacks into the tack tubes are not shown herein in detail.

AS shown, the drivers 462 of the tacker mechanisms are carried by the driver bars 460 which are mounted for sliding movement in guideways former in tacker slides 484 supported by the frame of the fastening mechanism. Detachably secured to each of the several tacker slides 484 are blocks 486 in each of which are formed, in accordance with the number of tacks to be driven, one or more slideways for the tack holders or nozzles 464. Each tack holder comprises a t be mounted for lengthwise movement in the corresponding slideway in the block 486 and bored centrally to receive a tack driver 452. At lower end the tack holder is shouldered for limiting engagement with the lower face of the tack block and is provided with a pair of tack fingers 483 which have complemental tack receiving recesses and are provided with cylindrical bearing por tions 49o mounted to turn in corresponding trans verse bearings in the lower end portion of the tack holder 464. To hold the tack fingers normally in closed elation springs 4S2 are pro-vi Fig. 15, the opposite ends of springs bein seated in recesses formed respectively in the tack fingers and in the tack holder member 454. Each of the tack holders 464 is provided with a slot 494 through which the tacks are fed from the tack tube 478, Fig. 13.

The tack holders 464 are held initially with their tack fingers 488 above the end wipers 180 during the over-wiping operation but are lowered to move the tack fingers into close proximity to the

openings

194, 196 in the wipers before the tacks are driven into the work. By reference to Fig. 13, it will be seen that there is mounted in each tacke slide 484 a controlling slide 496 which has a downwardly projecting plate 498 with an angled end portion arranged to extend within slots 500 in the several tack holders 464 with which the respective slide 484 is provided. The slide 496 is pressed downwardly by means of a spring 592 carried by the slide 484. The slide 484 is bored to receive the spring 502 which bears at one end against the slide 496 and at the other end against an adjusting screw 504 threaded into the upper end of the bore. In order to hold the slide 496 and the associated tack holders 464 initially in an upraised position above the wipers 180, the slide 496 is provided with a lug 506 which projects within a slot 508 formed in the driver car 460 and is engaged by a shoulder 510 on the driver bar to hold the tack holders in their uppermost positions. When the driver bar 460 receives its operative driving movement the spring 502 forces the slide 496 and the tack holders 464 downwardly, the limit of such downward movement being determined by the engagement of the downwardly projecting plate 498 with a shoulder 512 formed on the tack block 486.

In the construction shown the driver bar 460 of each tacker device is connected to the driving plate 458 by a tongue-and-groove connection.

During the driving operation this permits relative sliding movements between the plate 458 and the driver bars 469, which move in predetermined paths provided by their guideways in the tacker slides 484.

Since the corner members 96 of the heel-end embracing band act as stops to determine the lengthwise position of each shoe in the machine relatively to the fastening mechanism and the end wipers, the rearniost tacks are inserted at the same distance from the rear end. of the heel seat regardless of the size of the shoe operated upon. The tacker slide 484 of the rear end tacker device is accordingly secured to the frame of the fastening mechanism against inward movement over the heel seat of the shoe.

In order to determine the distance of the tacks from the edge of the heel seat along the sides of the shoe bottom, means is provided which will now be described for adjusting the side tackers in accordance with the size of the shoe being operated upon. The tacker slides 484 of the opposite side-tacking devices are mounted in the frame 455 of the fastening mechanism for sliding movements toward and from each other, laterally extending portions 514 of the slides 484 and the frame of the fastening mechanism being provided for this purpose with tongue-and-groove connections as clearly shown in 15. Each of the laterally extending por ions 514 has also a tongueand-groove connection with a block 516 at opposite sides thereof, this block being secured to the frame of the fastening mechanism intermediate between the opposite side tacks-r slides 484. Secured to each of the laterally extending portions 514 of the slides 484 is a plate 51.8 provided with an enlarged recess 520 into which extends a spring-pressed plunger 522. The plungers 522 are carried by the forwardly and rearwardly extending arms 524 of a lever 526 pivotally connected to the block 516 by a shouldered stud 528, Figs. 14 and 15.

The lever 526 has a lateraliy and forwardly extending arm 530 carrying at its outer end a spring-pressed locking pin 532 the reduced end portion 534 of which is arranged to enter one of a series of notches 536 formed in a bracket 538 adjustably secured to the frame 455 of the fastening mechanism. The notches 536 are spaced apart to determine the adjusted positions of the arm 530 and the side fastening-inserting devices in accordance with diirerent groups of sizes of shoes being operated upon. As clearly shown in Fig. 14, the frame of the fastening mechanism is provided with an arcuate slot 548 concentric with the axis of the stud 528 and extending into the slot 540 is a curved rib 542 formed upon the under side of the bracket 538. To permit adjustment of the bracket 538 about the axis of the stud 528 there is provided a screw-and-slot connection 544 between the bracket 538 and the frame of the fastening mechanism. It will be readily seen that by withdrawing the locking pin 582, the arm 580 of the lever 526 may be swung in a clockwise or counterclockwise direction as viewed in Fig. 14 to adjust the side tacker slides 484 toward or from each other to determine the distance of the tacks from the edge of the bottom of the shoe being operated upon, the slides 484 being held against movement from adjusted position by the locking pin 532 in one of the notches 586 formed in the bracket 588. As shown, particularly in Fig. 22, the openings 196 in the end wipers 180 are sufficiently elongated to permit the tacks along the sides to be spaced inwardly over the heel seat as may be desired by adjustment of the arm 530. Power for operating each fastening mechanism is derived from a sprocket gear 546, Fig. 2, on the continuously driven shaft 36, this gear 546 being connected by a chain 548 to a sprocket gear 550 which through

gearing

552, 554, Fig. 3, is operatively connected to a clutch member 556, Fig. 20, mounted to turn upon a shaft 558 mounted in suitable bearings formed in a bracket 566 secured to the frame of the fastening mechanism. The member 556 herein shown is one of the members of a pin clutch, although a clutch of any suitable .form may be used for driving the shaft 558. The clutch is controlled by a pivoted member 562 having a laterally extending arm 564 to which is pivotally connected a depending finger 566. The finger 566 is connected by a link 568 to the downwardly extending arm 576 of a bell-crank lever 572 pivotally connected tothe bracket 560 at 561 and having a laterally extending arm 574 carrying a roll 576. Secured to or formed upon the shaft 558 is a gear 578 the teeth of which mesh with the teeth of a gear 580 fast upon a shaft 582 mounted in suitable bearings formed in the frame of the fastening mechanism. Mounted on the shaft 582 is a cam 584 having a single throw which during rotation of the shaft 582 engages the roll 576 and swings the lever 572 in a clockwise direction as viewed in Fig. 21 against the infiuence of a spring 586 which tends normally to urge the lever 572 and through the link 568 the finger 566 in a counterclockwise direction. The movement of the finger 566 in a counterclockwise direction is limited by engagement of the hook-shaped end 588 of the finger with a pin 590 carried by a lever 592 fulcrumed at 594 to the bracket 560. The lever 592 is provided with an arm 596 to which is connected a downwardly extending rod 598 the lower end of which is connested at 600 to a lever 602 loosely mounted upon a transverse shaft 604, Figs. 2 and 6. The lever 662 carries a roll 606 which bears against the periphery of a cam 608 mounted upon the sleeve 46, the arrangement being such that as the sleeve 46 and the cam 608 are rotated the lever 592 is first swung in a clockwise direction under the influence of the spring 607 to permit the hook-shaped end 588 of the finger 566 to swing under the pin 590. Thereafter the lever 592 is swung in a counterclockwise direction to swing the pivoted member 562 through the finger 566 also in a counterclockwise direction and thus to cause the shaft 558 and through the gearing 578, 580 the shaft 582 to be connected to the source of power and thereby to start the tack-separating and delivering means and the tack-driving means in operation substan tially at the end of the overwiping operation. As previously stated the cam 584 is provided with a single throw which, as the can: 584 continues to rotate, acts to swing the lever 572 in a clockwise direction to release the finger 566-topermit the pivoted member 562 to be swung downwardly by a spring 669, Fig. 2, into position to stop the shaft 558 at the end of a single revolution.

Mounted on the shaft 582 is a lifting cam 610 which is connected to the driving arm 458 through a slide 614 in the same manner as in the patent to Baxter No. 1,700,970 hereinbefore mentioned. The driving arm 458 receives its driving impulse from rods 616, one of which is shown in Fig. 2, which are mounted in swivel blocks 618 at the opposite sides of the arm. Each rod 616 has secured to its lower end a collar 620 between which and the upper wall of a socket 622 is interposed a driving spring 624, the construction being such that when the shaft 582 is rotated the lifting cam 610 puts the driving springs 624 under compression and then releases them to cause them to operate the driving arm 458 and drive the tacks.

In the operation of the machine, briefly summarized, the operator adjusts the side tacker slides 484 in accordance with the size of the shoe to be operated on, mounts a shoe on one of the shoe-supporting jacks and after making any preliminary adjustments that may be necessary in order properly to position the shoe so that its heel seat may be moved into parallelism with the end wipers, starts the corresponding half of the machine in operation by depressing one of the treadles. Immediately upon the starting of the machine the cam 320 acts to swing the jack or shoe support rearwardly and to carry the shoe into engagement with the heel band, which limits the movement of the shoe into the machine and positions it also transversely of the machine in proper relation to the overwiping means and the tacking means.

After the shoe has been moved rearwardly into engagement with the heel band the cam 402 acts to impart a yielding heightwise movement to the jack to force the heel seat of the shoe into engagement with the holddown 370 to position the heel seat in the desired plane relatively to the wipers for the initial overwiping operation. The cam 92 then comes into play to close the heel band about the heel end of the shoe to clamp and shape the shoe upper materials to the contour of the last upon which the shoe is mounted, after which the wiper cam 224 becomes effective to impart to the end wipers their first overlast bottom they move the holddown 370 for- 3 wardly away from the margin of the shoe upper and relieve the pressure of the holddown on the shoe as hereinbefore explained. At this time a rise in the cam 402 causes a positive heightwise movement to be imparted to the shoe so that the margin of the shoe upper materials is subjected to increased pressure between the sole and end wipers 180. This pressure is preferably gradually applied as the wipers 180 continue their first overwiping movement. Following this first in ward movement of the wipers they are retracted substantially to their initial open position, the jack being lowered substantially to the position it occupied at the beginning of the first overwiping movement of the wipers. The wiper cam then imparts to the wipers another overwiping movement. After the wipers have been moved inwardly over the edge of the last bottom during their second overwiping movement, the cam 402 acts to impart a second and greater positive heightwise movement to the shoe which takes place gradually as the wipers are forced inwardly so as to apply still greater pressure to the margin of the shoe upper materials. As the wipers complete their second overwiping movement the cam 608 acts to start'the tack-driving mechanism in operation and the tacks are driven in the manner indicated for example in Fig. 18. Following the tack-driving operation the parts of the machine are returned to their starting positions, the jack being moved outwardly into inoperative position by the cam 320, and the tacks being fed into the tack holders in preparation for the operation of the machine on another shoe.
