- a bushing 78 integral with that plate abuts a -shoulder of the shaft and serves to prevent endwise movement of the shaft in one direction, its movement in the other direction being prevented by engagement of the plate 70 with an upturned arm 80 secured to the reduced end of the shaft 76.
- the holddown stem 64 is detachably held in the bore by means of a leaf spring 82 (Fig. 6) as shown in Fig. 6.
- a tension spring 84 is connected between the carrier 68 and the arm 3G, and movement in this direction is limited by engagement of a pin 36 in the arm with a lug 88 on the carrier 68.
- Movement of the shaft 76 clockwise (as viewed in Fig. 5) to raise the holddown again-st the action of the spring 84 is limited by engagement of a key 90 (Figs. 6 and 7) aixed in the shaft with an upper extremity of a slot 92 formed in the member 66.
- the holddown carrier 68 is provided with a boss 94 mounted for partial rotation on the upper end portion of an upright, vertically movable post 96.
- the arrangement is such that as the carrier 68 is swung about 90 clockwise (as viewed from above) by lmeans of a handle 98 to rnove the holddown 28 over the shoe, the holddown is lowered to operative position.
- a stem 100 in an axial bore formed in the upper end of the post 96 carries a pin 102 which extends laterally through a vertical slot 104 in that post and into a spiral slot 106 formed in the boss 94. Engagement of the pin 102 with the upper end of the slot 106 determines the limit of downward rotary movement of the holddown.
- the holddown is normally urged toward its inoperative position by a tension spring 108 connecting the boss 94 and the side bracket 20.
- the pin 1632 is adjustable heightwise.
- a flanged threaded sleeve 110 received by the threaded upper end of the stem 100 is retained axially by a cap 112 threaded onto the upper end of the post 96, the sleeve 110 being rotatable by means of a knurled knob 114 clamped on the upper end of the sleeve which projects through the cap 112.
- the post 96 When the holddown has been swung into operative position over the shoe bottom the post 96 may be depressed by means about to be described to urge the holddown against the shoe bottom, the post 96 being guided in a pair of alined bores in bosses one of which is shown as formed at (Fig. 5) on the bracket 20 and the other of which is not shown but is formed on the intermediate bracket 48.

- a lug 172 secured to the post 96 carries a pin 174 arranged to slide heightwise in, and engage the lower end of, a vertical slot '76 formed in the lower end of a rod 178.
- the upper end of this rod is pivotally connected to an arm 180 that has an end ⁇ lixedly mounted on the pivot shaft l58.
- the last of the downward movement of the post 96 acts through the pin 174 and the rod 7.78 to shift the shaft 258 clockwise, as viewed in Fig. 4, and thus moves the pin 16) downwardly against resistance of the spring 252 so that the lever 148 may lock the toe rest post 42, any further downward thrust on the toe pad .38 tending to cause the lever 148 to bind the post 42 more firmly.
- the insole of the shoe is arranged in appropriate heightwise relation to the inward wiping plane of the heated wipers 34, the limit of downward movement of the post 96 being determined by engagement of the treadle 139 with a bracket 182 (Fig. l) secured on the frame.
- the holddown carrying post 96 is locked in its depressed position by means of a latch plate 184 (Fig. 4) on an arm 186 pivotally mounted on a bracket 188 aiiixed to the side bracket 28.
- the latch plate 184 by means ot a pin 185 carried thereby is arranged to be urged by a spring i538 into abutment with a shoulder of a stop plate 182 secured to the post 96, the spring connecting a pin 5185 projecting from the arm l86 with the machine frame.
- a shoe is rst located lengthwise in the machine prior to operation of the holddown by engaging the outside of the upper at the toe extremity with the spreader-retarder member 32, the top of the toe then being supported on the toe rest 26 with the left hand, and the right hand being used to move the heel rest 3@ forwardly against the resistance of springs 2538 (one only shown in Fig. l) which are then allowed to urge the heel rest into shoe clamping relation with the member "ihe heel rest comprises a transversely curved face 262 adapted to engage the heel end of the shoe and a forwardly extending split portion 284 that is pivotally supported by a pin 286 carried by a lug on a block 288.
- the block 288 is adjustable widthwise to accommodate shoes diiering considerably in size and style, the block being secured by a clamp screw 212 extending through a slot extending lengthwise of a bar 214.
- the bar 214 is supported by the upper ends of parallel levers 216, 216 which have their mid portions connected, for a purpose to be explained, by a rod 218 and are fulcrumed at their lower ends on a bracket 220;
- the bracket 220 is slidable on a guide member 222 bolted on a front bracket 224 secured to the intermediate bracket 48, a clamp screw 226 extending through a vertically disposed slot in the bracket 220 to secure the latter relatively to the member 222.
- a pair of coaxial pivot shafts 228 are journaled in the ripper ends of oppositely disposed portions of the front bracket 224, the above-mentioned springs 200 being connected at their lower ends, respectively, with side frame members 14, 16 and having their upper ends connected to arms 230, 230, respectively, mounted on the shafts 228.
- Oppositely disposed arms 232, 232 (Fig. 2) also secured to the shafts 228, respectively, are connected to parallel links 234, 234 having notches 236 adapted to receive the rod 218 in a selected position.
- the rod 218 would normally be seated in the more rearward notches 236 when operating upon smaller sized shoes.
- the mechanism employed for locking the toe rest 26 heightwise with the holddown 28 is also used to lock the heel rest in position to sustain the shoe against operating stresses imparted by the band 36 and the wipers 34.
- a set screw 240 in an end of an arm 238 keyed on the shaft is lowered, thereby permitting a spring allixed at its lower end to the front bracket 224 to swing a pawl 244 pivotally mounted thereon into locking relation with the ratchet teeth 246 of a segment 248 that is secured to one of the shafts 228.
- a similar segment 248 mounted on the other shaft 228 also is arranged to be engaged by a pawl pivotally mounted on the bracket 224, this second pawl likewise being controlled by a tension spring (not shown) and a set screw threaded on the arm (Fig. 4) that is aiiixed to the opposite end of 'the shaft 158.
- the iirst of the lasting instrumentalities to be actuated is the spreader-retarder 32 which has its movements controlled by a single hand lever 250 (Figs. l and 2).
- This lever is secured to a pivot pin 252 mounted in a bracket 254 affixed on a bracket 256 which is, in turn, secured to the bridge member 24.
- the spreader-retarder constitutes a foot formed to correspond generally to the toe end of a shoe bottom and provided with a fiat bottom engaging surface, and an upwardly extending portion 260 provided with a pin 262 that is received in vertically disposed slots 264 formed in lugs 266 on the bracket 256.

- a cam roll 514 carried by the arm 510 rides in a cam track 516 formed in a member 518 pivoted on a pin 520 on a carrier 522 that is freely rotatable on the shaft 478. Portions a ⁇ and b of the cam track are at certain times concentric with the axis of the shaft 478 and are separated by a portion c.
- an arm 526 is pivoted 0n an arm 528 of the carrier 522.
- a spring 530 connecting the latter with the arm 526 may urge it clockwise, as seen in Fig. 2, to cause a latch 532 on that arm to engage a catch plate 534 secured to the member 518 and thus prevent the member from swinging clockwise on the pin 520.
- the latch 532 may be held clear of the plate 534 against the influence of the spring 530, depending on the position of an operating arm 536 affixed on the shaft 478 as controlled (through linkage above described) by operating movements of the hand lever 440.
- the arm 536 is provided with opposite faces 538, 540 arranged to engage oppositely disposed stop faces of an abutment 542 formed on the member 518.
- the operating arm 536 is swung clockwise (as seen in Fig. 2) relatively to the carrier 522 to cause the face S38 to engage the abutment 542 and thus allows the latch arm 526 to swing clockwise sufficiently to effect latching of the plate 532 with the plate '534.
- the portion c of the cam track acts on the cam roll 514 to move the lever 508, 510 counterclockwise as seen in Fig. 2.
- the operating arm 536 is suiciently swung counterclockwise (as seen in Fig. 2) by such movement of the lever to cause the face 540 to engage the abutment 542.
- an arm 554 (Fig. 8) having a cam face 556 is pivoted on a shaft S58 secured in the bracket 48.
- a link 560 (Figs. 2 ⁇ and S) pivotally connects the arm 424 with the arm 554.
- a knee pad 564 is provided (Figs. 1 and 12) which is secured to a bar 566 adjustably secured to one arm 568 of a bell crank lever 570. This lever is fulcrumed on a pin 572 carried by a bracket 574 secured to the intermediate bracket 48.
- the lever 570 is pivotally connected by means of a pin 576 to one end of a link 578, the other end of the link being connected by a pivot pin 580 (Figs. l, 4 and l2) to an 'arm 582 secured to a cross shaft 584.
- the shaft 584 is journaled in a bracket S86 secured to the right-hand side bracket 20.
- Secured to the cross shaft 584 is an upwardly extending arm 588 having an upper end portion biturcated to embrace the link 490 and yarranged to engage a block S90 adjustably secured to a slotted portion of the link 490.
- a lug 592 (Fig. l2) on the lever S70 limits clockwise movement of the latter upon engagement with a pin i594 in the bracket 574. Displacement of the knee pad Accordingly, clockwise Y' to the right, as seen from the front of the machine,
- the operator initially makes room for easy insertion of a shoe to be lasted by moving the heel rest 202 forwardly while he places the upper at the toe end of the shoe in abutment with the spreader-retarder 32 (Fig. 13).
- the heel rest as effected by the springs 200, yieldingly to clamp the shoe in cooperation with the spreaderretarder and thus position the shoe lengthwise with the toe on the toe rest 26
- the holddown 28 is swung over the shoe bottom by means of the handle 98, as indicated in Fig. 5.
- the holddown is lowered and caused to clamp the shoe against the toe rest pad 38 by depressing the jacking treadle 130.
- this treadle may be released, the holddown carrying post 96 and toe rest carrying post 42 then being automatically locked with the shoe held in position to be operated upon and fixed against heightwise movement.
- This treadle action also automatically assures locking of the heel rest to prevent heelward displacement of the shoe during the lasting operation, the rod 178 and the arm 238 being actuated by the post 96 and operating the pawl 244 to hold the segment 248 against pivotal movement.
- the operator manipulates the spreader-retarder 32 by means of the hand lever 250 as hereinbefore explained.
- rearward swinging of the lever 250 raises the spreaderretarder 32 from its gaging position and moves it above the erect portions of the lasting margin.
- Further rearward movement of the lever 250 to interengage the latch plates 296, 302 moves the spreader heelward.
- the spreader is moved down onto the shoe bottom and the margin of the stock is spread outwardly over the toe band 36, as shown in Fig.
- the holddown 28 having braced the insole against displacement or distortion until the Wipers 34 cross the insole edge, the forward movement of the hand lever 440, acting through mechanism including the arm 496, the link 490, and the latch 184, permits spring release of the holddown to its inoperative position to clear the way for the wipers.
- the toe support 26 and the heel rest 30 remain locked during the lasting since upward movement of the post 96 merely raises the pin 174 idly in the slot 176.
- the eccentrics 500 cause increased dwell of the wipers in overlasted position as the nature of the cement and the type of stock seem to warrant, the return or rearward movement of the lever 449 restores the wiper controlling parts to their original positions.
- the pressure of the wipers on the shoe bottom is automatically diminished almost immediately upon such return movement of the hand lever llil as above explained. With the wipers retracted from over the shoe bottom the lasted shoe may be removed from the machine. lt will be appreciated that the invention thus affords a toe lasting machine of compact, reliable organization, and one that is easily as well as economically operated.

Claims priority, application Great Britain November 10, 1953 28 Claims. (Cl. 1'2-82) This invention relates to lasting machines, and more particularly to machines for lasting the toe ends of shoes when an adhesive is used to secure the marginal portion of the uppers in lasted relation to their insoles. Although the invention is herein illustrated as embodied in a manually operable cement toe lasting machine resembling in some respects the type generally disclosed, for example, in the United States Letters Patent No. 2,146,762, granted February 14, 1939 upon an application of A. F. Pym et al., it is to be understood that the invention, in various novel aspects, is not limited to machines of that character nor is it applicable solely to lasting with an adhesive.
In lasting the toe portions of shoes wipers have heretofore normally performed what is termed an upwiping operation as an upper and the wipers are relatively moved heightwise of the shoe, and the wipers are thereafter required to embrace the toe adjacent to the shoe bottom and then wipe the stock to be lasted inwardly over the shoe bottom and into lasted relation thereon. In conjunction with the overwiping operation the use of heated wipers has been found advantageous in several ways such as, for example, in smoothing out the overlasted stock for the better reception of an outsole, and in reducing the time required for obtaining suitable adhesive bond between a precemented lasting margin and an insole. The
application of heat at the relatively high temperature rev quired for superior results at once necessitates that precaution be taken to avoid contact between a heated Wiper and any portion of a shoe upper which would be exposed in the finished shoe lest the shoe thereby be marred. A further important consideration in conjunction with the care essential to manipulation of the heated wipers is that, for best lasting performance, the operator of the machine should be assured that he at all times can maintain full control over the upper as it is drawn down to the top of the toe of the last and then worked into overlasted position.
Having the above in mind, it is an object of this invention to provide an improved machine with Whch an operator may conveniently, and without great effort or the aid of auxiliary power, perform the lasting operation efficiently and effectively. To this end, and in accordance with one feature of the invention, the illustrative organization includes a novel combination of lasting instrumentalties comprising a toe band for performing an upwiping operation on the toe of a shoe, a pair of heated wipers movable heightwise to their operative plane by the toe band and while spaced lengthwise from the shoe, a member movable toewardly over the shoe bottom and biased toward the toe band to spread outwardly and yieldingly clamp thereon, prior to the upwiping operation, the upstanding margin of the stock to be lasted, and means for advancing and closing the heated wipers in their operating plane, when the toe band has been moved into predetermined heightwise relation to the shoe bottom, to
2,758,323 Patented Aug. 14, 1956 ICC Wipe the lasting margin of the upper at the toe of the shoe inwardly into overlasted position.
In the construction shown, which is Well adapted to operation on childrens footwear, and as another feature of the invention, the machine is provided with conveniently operable shoe supporting means including a spreaderretarder member that is initially engageable with the outside of the upper at the toe end of a shoe to locate it lengthwise. For facility in operating this member in its successive functions as an end gage, upper spreader, and lastly a retarder, a single hand control lever is provided and mounted to swing about a horizontal axis, the lever thus being simply movable heightwise forwardly, and then rearwardly to accomplish requisite control of the lasting margin of the upper in preparation for lasting. The illustrative machine is intended for use on uppers mounted lon lasts positioned bottom upward, the shoes being of the type in which the margins of the uppers are lasted over the insoles in generally parallel relation to the bottoms of the lasts. For holding a shoe, first in cooperation with the spreader-retarder member while it functions as a toe end gage and then as it is released and operated to spread the lasting margin of the upper at the toe outwardly over the toe band, the machine further includes manually operable shoe supporting means comprising a holddown engageable with the shoe bottom, a toe rest normally yieldable heightwise of the shoe with the holddown, and a heel rest for holding the shoe against heelward movement during operation of the toe band and wipers. As herein shown, the heightwise position of a shoe in said shoe supporting means, when locked therein by operation of a jacking treadle, is predetermined by adjusting mechanism associated with the holddown.
The above and other features of the invention, including various novel details of construction and combinations of parts, all tending to alord an operator full control of the stock to be lasted as the lasting progresses, will now be more particularly described in connection with an illustrative embodiment and with reference to the accompanying drawings thereof, in which Fig. 1 is a view in left-hand side elevation of the illustrative machine in which the present invention is embodied, portions being broken away to reveal structural details;

rThe frame of the illustrative machine comprises oppositelyA disposed side members 14, 16 (Fig. l) to the upper ends of which are bolted side brackets 18, 20, respectively. These brackets have depending front portions bridged by a plate 22 and rear portions connected by a bridge member 24. For positioning a shoe presented bottom up to the machine there is supported by the frame as will be described a toe rest 26 engageable with the top of the toe of the shoe mounted on its last, a holddown 28 engageable with the forepart of an insole on the last to clamp the shoe against the toe rest 26, and a heel rest 30 engageable with the heel end face of the shoe. The lasting instrumentalities, each of which is arranged to be operated manually by means to be explained, comprise a spreaderretarder member 32 (Figs. 2, 13) that initially serves as a toe end gage, a pair of heated wipers 34 (Fig. 11) and a toe band 36. The detailed description now to follow will relate first to the shoe positioning means and thereafter to the lasting instrumentalities.
The toe rest 26 includes a yieldable pad 38 (Fig. 8) shaped to receive the top of the toe of the inverted shoe, the pad being mounted on a block 40 that is detachably secured to the upper end of a vertically movable post 42 by means of a pair of pins 44 (Figs. 8 and l1) extending downward from the block and into bores formed in the post. Heightwise movement of the toe rest is guided by alined vertical bores 46 (Fig. 8) formed in an intermediate bracket 48 secured to the plate 22, the post 42 being restrained against rotation in the bores 46 by a key 50 (Fig. 8) `screwed to the bracket 48 and extending into a vertical groove formed in the post. When a shoe is depressed in the machine by means to be described the pad 38 may yield downwardly from its normal position against the resistance `of a compression spring 52 (Fig. 2) the upper end of which is seated in an 4annular recess formed in the post 42 and which surrounds an axially depending stem 54 of the post 42. The lower end of the spring 52 is `seated in an axial bore of an adjusting member 56 threaded into the lower end of one ofthe bores 46. A nut 58 threaded on the stem 54 normally limits upward movement of the post 42 relatively to the adjusting member S6 and is secured in adjusted position by a locknut 60. Thus the arrangement is such that the resistance of the spring 52 may be adjusted as desired by rotating the nuts 58, 60, land while this will affect initial heightwise positioning of the pad 38, such positioning may be corrected without affecting the spring resistance by merely turning the adjusting member 56 as required.
The holddown 28 (Figs. 1, 5 and 6) with which the toe rest is cooperative is a flat plate having an outline corresponding substantially to that of the toe of an insole :on the shoe bottom and is suiiiciently stift to brace the insole against buckling during the wiping operations. Initially the holddown 28 occupies an inoperative position forwardly and to one side of the machine, a-s indicated in Fig. l, but manually operable means now to be described is provided whereby the holddown may be swung downwardly and rearwardly into insole engaging position on a shoe supported by the pad 38. Thus, the holddown is integral with an arm 62 secured to a cylindrical stem 64 journaled in a tubular member 66. The latter is received in a horizontal bore formed in a carrier 68. The latter is secured to the member 66 by means of a plate 70 integral with an end of the member and bolts 72 extending through the plate and into the carrier. An end of the stem 64 has a tongue 74 (Fig. 6) extending in a recess in one end of a shaft 76 also in the bore `of the member 66, the other end of the shaft extending with reduced diameter beyond the plate 70. A bushing 78 integral with that plate abuts a -shoulder of the shaft and serves to prevent endwise movement of the shaft in one direction, its movement in the other direction being prevented by engagement of the plate 70 with an upturned arm 80 secured to the reduced end of the shaft 76. The holddown stem 64 is detachably held in the bore by means of a leaf spring 82 (Fig. 6) as shown in Fig. 6. To urge the holddown 28 toward a shoe bottom a tension spring 84 is connected between the carrier 68 and the arm 3G, and movement in this direction is limited by engagement of a pin 36 in the arm with a lug 88 on the carrier 68. Movement of the shaft 76 clockwise (as viewed in Fig. 5) to raise the holddown again-st the action of the spring 84 is limited by engagement of a key 90 (Figs. 6 and 7) aixed in the shaft with an upper extremity of a slot 92 formed in the member 66.
The holddown carrier 68 is provided with a boss 94 mounted for partial rotation on the upper end portion of an upright, vertically movable post 96. The arrangement is such that as the carrier 68 is swung about 90 clockwise (as viewed from above) by lmeans of a handle 98 to rnove the holddown 28 over the shoe, the holddown is lowered to operative position. For this purpose a stem 100 in an axial bore formed in the upper end of the post 96 carries a pin 102 which extends laterally through a vertical slot 104 in that post and into a spiral slot 106 formed in the boss 94. Engagement of the pin 102 with the upper end of the slot 106 determines the limit of downward rotary movement of the holddown. The holddown is normally urged toward its inoperative position by a tension spring 108 connecting the boss 94 and the side bracket 20. For adjusting the position of the carrier 68 heightwise relatively to the post 96 and thus determine the heightwise position of a shoe bottom in the machine, the pin 1632 is adjustable heightwise. For thi-s purpose a flanged threaded sleeve 110 received by the threaded upper end of the stem 100 is retained axially by a cap 112 threaded onto the upper end of the post 96, the sleeve 110 being rotatable by means of a knurled knob 114 clamped on the upper end of the sleeve which projects through the cap 112. By turning the knob 114 the pin 102 is thus initially adjusted heightwise to determine the proper level for the holddown carrier 68.
When the holddown has been swung into operative position over the shoe bottom the post 96 may be depressed by means about to be described to urge the holddown against the shoe bottom, the post 96 being guided in a pair of alined bores in bosses one of which is shown as formed at (Fig. 5) on the bracket 20 and the other of which is not shown but is formed on the intermediate bracket 48. For holding the post 96 against turning about its axis a screw carried by the bracket 2l) extends into a vertical way formed in the post.
During heightwise movement of this post the holddown itself is maintained in operative position against the inuence of the spring 108 by a roll 122 carried by a stud 124 projecting from the carrier 68, the roll 122 being arranged to be received within a vertical recess 126 formed in a plate 128 aixed to the bracket 20. This arrangement also serves to limit clockwise movement (as seen from above) of the carrier 68 about the post 96. For lowering the post (and hence the holddown 28) a jacking treadle 130 is depressed, the post being pivotally connected to the treadle by a link 132 (Fig. l). The treadle is fulcrumed on a pin 134 supported transversely of the machine by a bracket 136 secured to the machine frame and is yieldingly suspended on a return spring 138 connected to the frame member 14. After engagement of the holddown 28 with the insole, further depression of the treadle 130 causes the stem 64 and the shaft 76 to rotate in the tubular member 66 as permitted by the spring 84, the latter being weaker than the spring 52, until the key 90 has engaged the upper end of the slot 92. Thereafter any further depression of the treadle 130 causes the holddown rmly to clamp the shoe against the toe rest 26, any slight yield in the pad 38 depending upon the particular adjustment made for the spring 52.
Means are provided whereby the operator may release the depressed treadle 130 and the clamped shoe will nevertheless be held locked in its predetermined heightwise position, both the rest carrying post 42 and the holddown carrying post 96 then being restrained against movement. With reference to Fig. 8, a locking lever 140 for thus acting on the post 42 is fulcrumed at one end on a pin 142 which extends through slots 144 formed in spaced lugs 146 on a bracket 148. rIbis bracket is secured to the plate 22 and is provided with a forwardly extending arm i) projecting just above the lever 140 and through an aperture in the intermediate bracket 48. The lever 146 is provided with a bore for receiving the post 42, the bore being defined by ared cramping walls 151 above and below a central portion which has a diameter only slightly larger than that of the post 42 in that area. The arrangement is such that, when the locking lever i4@ is horizontally disposed and the post 42 is slidable vertically in the bore, an upper face of the lever engages a surface of the arm 150, the latter also having a bore through which the post extends. The locking lever 24) is normally held in its initial, horizontal position by a compression spring 152 in a bore in the bracket 148 and acting on an arm 154 of a bell crank lever 156 keyed on a pivot shaft 1158 journaled in the intermediate bracket 48. For this purpose a forwardly extending arm of the lever 156 supports a pin 16d arrange to extend into a slot 162 disposed vertically in the upper end of a link 164, the lower end of the link 164 being pivotally connected by a pin 166 to the forward end or" the locking lever 140.
By linkage now to be described, and near the end of the downward movement of the holddown carrying post 96, the lever 148 is permitted to be swung7 under the influence of a pair ot tension springs 278 into cramping relation with the post 42. As indicated in Fig. 4, a lug 172 secured to the post 96 carries a pin 174 arranged to slide heightwise in, and engage the lower end of, a vertical slot '76 formed in the lower end of a rod 178. The upper end of this rod is pivotally connected to an arm 180 that has an end `lixedly mounted on the pivot shaft l58. Accordingly, the last of the downward movement of the post 96 acts through the pin 174 and the rod 7.78 to shift the shaft 258 clockwise, as viewed in Fig. 4, and thus moves the pin 16) downwardly against resistance of the spring 252 so that the lever 148 may lock the toe rest post 42, any further downward thrust on the toe pad .38 tending to cause the lever 148 to bind the post 42 more firmly. As thus positioned and clamped, the insole of the shoe is arranged in appropriate heightwise relation to the inward wiping plane of the heated wipers 34, the limit of downward movement of the post 96 being determined by engagement of the treadle 139 with a bracket 182 (Fig. l) secured on the frame. The holddown carrying post 96 is locked in its depressed position by means of a latch plate 184 (Fig. 4) on an arm 186 pivotally mounted on a bracket 188 aiiixed to the side bracket 28. The latch plate 184, by means ot a pin 185 carried thereby is arranged to be urged by a spring i538 into abutment with a shoulder of a stop plate 182 secured to the post 96, the spring connecting a pin 5185 proiecting from the arm l86 with the machine frame.
As above noted, a shoe is rst located lengthwise in the machine prior to operation of the holddown by engaging the outside of the upper at the toe extremity with the spreader-retarder member 32, the top of the toe then being supported on the toe rest 26 with the left hand, and the right hand being used to move the heel rest 3@ forwardly against the resistance of springs 2538 (one only shown in Fig. l) which are then allowed to urge the heel rest into shoe clamping relation with the member "ihe heel rest comprises a transversely curved face 262 adapted to engage the heel end of the shoe and a forwardly extending split portion 284 that is pivotally supported by a pin 286 carried by a lug on a block 288. A spring plunger 2li? seated in the block 268 urges the face 282 counterclockwise, as seen in Fig. 2. The block 288 is adjustable widthwise to accommodate shoes diiering considerably in size and style, the block being secured by a clamp screw 212 extending through a slot extending lengthwise of a bar 214. vThe bar 214 is supported by the upper ends of parallel levers 216, 216 which have their mid portions connected, for a purpose to be explained, by a rod 218 and are fulcrumed at their lower ends on a bracket 220; For adjusting the heel rest 3) heightwise the bracket 220 is slidable on a guide member 222 bolted on a front bracket 224 secured to the intermediate bracket 48, a clamp screw 226 extending through a vertically disposed slot in the bracket 220 to secure the latter relatively to the member 222. For controlling the heel rest lengthwise of the shoe a pair of coaxial pivot shafts 228 are journaled in the ripper ends of oppositely disposed portions of the front bracket 224, the above-mentioned springs 200 being connected at their lower ends, respectively, with side frame members 14, 16 and having their upper ends connected to arms 230, 230, respectively, mounted on the shafts 228. Oppositely disposed arms 232, 232 (Fig. 2) also secured to the shafts 228, respectively, are connected to parallel links 234, 234 having notches 236 adapted to receive the rod 218 in a selected position. (Only one of the members 228, 230, 232, 234 respectively is shown in the drawings.) As will be apparent, the rod 218 would normally be seated in the more rearward notches 236 when operating upon smaller sized shoes.
Advantageously the mechanism employed for locking the toe rest 26 heightwise with the holddown 28 is also used to lock the heel rest in position to sustain the shoe against operating stresses imparted by the band 36 and the wipers 34. Thus, when the pivot shaft 158 is turned clockwise, as seen in Fig. 2, during the locking of the posts 96 and 42, a set screw 240 in an end of an arm 238 keyed on the shaft is lowered, thereby permitting a spring allixed at its lower end to the front bracket 224 to swing a pawl 244 pivotally mounted thereon into locking relation with the ratchet teeth 246 of a segment 248 that is secured to one of the shafts 228. In like manner a similar segment 248 mounted on the other shaft 228 also is arranged to be engaged by a pawl pivotally mounted on the bracket 224, this second pawl likewise being controlled by a tension spring (not shown) and a set screw threaded on the arm (Fig. 4) that is aiiixed to the opposite end of 'the shaft 158.
The iirst of the lasting instrumentalities to be actuated is the spreader-retarder 32 which has its movements controlled by a single hand lever 250 (Figs. l and 2). This lever is secured to a pivot pin 252 mounted in a bracket 254 affixed on a bracket 256 which is, in turn, secured to the bridge member 24. The spreader-retarder constitutes a foot formed to correspond generally to the toe end of a shoe bottom and provided with a fiat bottom engaging surface, and an upwardly extending portion 260 provided with a pin 262 that is received in vertically disposed slots 264 formed in lugs 266 on the bracket 256. For purposes to be explained a link 268 carries in its bifurcated forward end a pin 270 projecting through a slot 272 extending heightwise in the portion 260. The rearward end of the link 268 is pivotally supported by the lower end of an arm 274 that is itself pivotally supported by its bifurcated upper end portions by the pin 252. The lower end of a link 276 is also pivotally connected to the link 268. An upper end of the link 276 is pivotally connected by a pin 278 to an arm 280 that is attixed at one end, between the split ends of the arm 274, to the pin 252. Movement of the arm 280 by the lever 258 is limited by upper and lower lugs 282, 284 arranged on this arm for engagement respectively with lugs 286, 288 on the arm 274. A tension spring 290 connected to the bracket 256 acts on the lever 250 to urge the arm 280 clockwise, as seen in Fig. 1, so that when the lugs 284, 288 are in engagement the arm 274 abuts a stop face on the bracket 254 and, through the link 268, thus determines the initial rearward position of the spreader-retarder 32 when it functions as a toe end gage as shown in Fig. 13. A tension spring 292 connects the pin 262 with the pin 270. Normally, therefore, under the influence of the link 276 the link 268 holds the pin 270 down so that the spring 292 acts on the pin 262 and thus maintains the spreader-retarder in toe end engaging position, indicated in Figs. 2 and` 13, the pin 262 then engaging the lower ends of the slots 264 while the pin 270 engages the upper end of the slot 272.
When the spreader-retarder 32 is to be raised from its gaging position and carried heelwardly over the upstanding margin of the upper at the toe, the shoe having been clamped by the means above described, the hand lever 250 is swung rearwardly from its position shown in Fig. 2. As a result the arm 280 acts on the link 276 to swing the link 268 counterclockwise, as seen in Fig. 2, and thus lifts the portion 260, the pin` 262 moving upwardly in the slots 264. Upon continued rearward movement of the 'hand lever 250, the lug 282 having been brought into engagement with the lug 286, the arm 274 is also swung counterclockwise bodily to shift the link 268, and hence the spreader-retarder member 32, forwardly as the portion 260 is pivoted about the pin 262 and against the resistance of a pair of springs 294, respectively, connecting opposite ends of the pin 27 0 with the bridge member 24. The lever 250 is moved rearwardly until a latch plate 296 carried by an arm 2981 that is pivotally mounted on the bracket 254 is urged, by a spring 300 acting on the arm 298, upwardly into cooperative relation with a latch plate 302 carried by the arm 274. The operator being satisfied that correct conditions prevail for the lasting of the shoe, he now moves the lever 258 forwardly to lower the spreader-retarder onto the shoe bottom and effects its release for toeward movement. Thus, the arm 274 being held in its forward position by the latch plates 296 and 302, as the lug 282 is moved from the lug 286, the link 276 is depressed and consequently the spreader-retarder 32 is yieldingly lowered onto the shoe bottom against resistance of the spring 292. An abutment 304 (Fig. 2) formed on the link 276 is arranged to engage the arm 298 and thereupon displaces the latch plate 296 to free it from the latch plate 302. Accordingly, continued forward movement of the hand lever 250 elects engagement of the lug 284 with the lug 288 and swings the arm 274 rearwardly about the pivot pin 252 causing the spreader-retarder to move rearwardly with the assistance of the springs 294 and to spread the margin of the upper at the toe outwardly over the toe band 36 as indicated in Fig. 14. When the spreader-retarder has thus been moved beyond the toe edge of the insole the spring 292 acts yieldingly to clamp the spread f margin against the top of the toe band, the heated wipers 34 then occupying retracted positions in which they cannot by contact mar the upper in a portion which would be visible in the inished shoe. At this stage in the lasting operation the hand lever 250 may be released, the ensuing tensioning of the upper about the toe end heightwise of the shoe by upwiping action of the toe band being effected cooperatively with the spreader-retarder as controlled by treadle actuated means later described.
The toe band 36 (Figs. 2, 3 and 9) is supported on a carrier bracket 308 which, in turn, is supported by a parallel linkage arrangement hereinafter explained. The toe band consists of a leather-faced spring steel strip having secured at each end a block 310. A stem 312 of each block is received in a bore formed in an arm 314, the arms 314 being respectively received in biturcated front end portions of adjusting levers 316, 318 and pivoted thereto by means of pins 320. The levers 316, 318 are respectively fulcrumed on studs 322 (Figs. 9 and 10) secured in bosses 324, respectively, on arms 326, 326 pivotally mounted on studs 328 upstanding on the carrier bracket 308. The levers 316, 318 rest on a plate 330 secured to the bracket 308. The bosses 324 extend downwardly through a U-shaped recess 332 in the plate 330 and throughslots 334 respectively disposed transversely in the carrier bracket 308. Slotted lugs 336 formed on the levers 316, 318 receive an equalizer pin 338 upstanding from a slide 340 and the latter is adapted to receive a dove-tailed guide member 342 secured centrally to the top of the carrier bracket 308. The pin 338 is thus guided lengthwise in the machine for cqualizing movement of the levers 316, 318 on their studs 322, 322 when the toe band 36 is opened or closed by adjusting means about to be described. It may be noted that a U-shaped recess 344 (Fig. 9) in the plate 330 affords clearance for the toe portions of shoes, and that a block 346 affixed to a mid portion of the toe band is slidable rearwardly on the plate to a limit determined by a stop 348 axed therein. For shoes of dilerent sizes the toe band curvature is modied by turning a handle 350 fast on a rod 352. The latter, accordingly, has end portions provided with threads of opposite hands, the rearward end being received transversely by a trunnion pin 354 extending heightwise in a bifurcated portion of the lever 316, and the forward end being received transversely in a threaded bore of a trunnion pin 356 mounted in a bracket 358 secured to the carrier bracket 308.
The carrier bracket 308 is pivotally supported at its rearward end on alined shafts 360, 360 mounted in the side brackets 18, 20 respectively. The front end of the bracket 308 is supported on upper ends of a pair of links 362 (Figs. 2 and 3) spaced widthwise of the machine by means of pins 364. Pivot pins 366 respectively connect the lower end of the links 362 to a cradle 368 the rearward end of which has spaced bosses formed thereon for pivotally receiving a transverse shaft 370 journaled in the side brackets 18, 20. Extending downwardly from one of the bosses is an arm 372 having connection with treadle operated means for raising and lowering the toe band 36 as will now be described, it being noted that the toe band is supported by a parallel linkage since the effective length of the links 362 is equal to the distance between the axes of the shafts 378, 360, and the distance between the axes of the pins 366 and the shaft 370 is equal to the distance between the axes of the pins 364 and the shaft 360. The toe band is raised by swinging the cradle 368 counterclockwise (as viewed in Fig. 3) about the shaft 370 and for this purpose a rocking treadle 374 (Fig. l) is operatively connected to the arm 372. Thus a link 376 (Fig. 3) connects the latter with an arm 378 of a bell crank lever 380 (Figs. l and 3) mounted on a cross shaft 382 journaled in the side brackets 18, 20. Another arm of the lever 380 is connected by a link 384 to one end of a lever 386 (Fig. l) mounted on a fulcrum stud carried by the bracket 1182. The other end of the lever 386 is connected to the treadle 374 by a link 388 and the treadle is pivotally supported by a pin 390 in the bracket 182. For at least partially balancing the weight of the parts associated with the toe band mechanism a pair of compression springs 392 (Fig. 3) is provided between lugs 394 on the cradle 368 and lugs on the side brackets 18, 20. The lugs 394 serve also adjustably to limit upward movement of the toe band by engagement with stop screws 396 carried by the brackets 18, 20. Downward movement of the toe band is limited by a stop screw 398 (Fig. 2) in the side bracket 20 en gageable with the arm 372.
As will now be explained means is provided for raising and lowering the heated wipers 34 together with the toe band 36, the wipers being open and retracted from the shoe as they are raised to a predetermined level with respect to the insole and the -top of the toe band. The wipers in the form of plates detachably mounted in holders 400 (Fig. 11) are held therein by headed pins 402. The holders 400 have arcuate grooves 404 formed in their under faces for receiving arcuate ribs formed on the upper face of a wiper carrier 486 (Figs. 2 and 3). A cover plate 408 secured to the carrier 406 by bolts 410 retains the holders and they have arcuate outer walls 412 (Fig. 1l) concentric with the grooves 404 for riding in contact with arcuate guide walls 414 vformed on the carrier 406. Electrically energized heating elements 416 in the holders 400 are connected by wires in a conduit 417 (Figs. l and 11) to suitable means for controlling the heating of the respective wipers. VThe wiper carrier 406 is supported by parallel linkage to Vbe described and is pivotally supported at its rearward end by means of a pin 420 (Fig. ll) on a pair of upwardly extending arms 422 of a three-armed lever having a downwardly extending arm 424. The pin 420 is coaxial with the shafts 360 (supporting the toe band carrier) at the start of a cycle of operations of the machine. The lever 422, 424 is secured on the shaft 370 and the arms 422, 422 have a connecting yoke portion 426 indicated in Fig. 2.
The 4front of the wiper carrier 406 is pivotally supported by means of pins 428 in the upper ends of a pair of arms 430 spaced widthwise in the machine and connected by a web (not shown). Lower ends of the arms 430 are provided with bosses through alined bores in which a cross shaft 432 carried by the cradle 368 extends. The particular manner in which the cradle 368 carries the shaft 432 is hereinafter explained. The arrangement is such that the effective lengths of the arms 422 and 430 are equal and effectively parallel; also the arms 430 and the links 362 are elfectively equal in length and parallel to cause joint heightwise movement of the toe band and wipers upon rocking of the treadle 374. Such heightwise movement (Fig. 14) of the toe band and the spreader-retarder tensions heightwise the stock to be lasted.
Closing movements of the wipers 34, when they have been raised to a wiping level substantially even v/ith the upper surface of the insole, are caused by advancing the wiper carrier 406 under the control of a hand lever 440 (Figs. l and 2) operative as will subsequently be described. For wiper closure each of the holders 400 has secured therein a stud 442 (Fig. 1l) extending upwardly through an arcuate slot 444 in the cover plate 408. A pair of links 446 respectively connect the studs 442 with the other studs 448 received in levers 450, 450 respectively. Each of these levers is fulcrumed on a stud 452 carried by the wiper carrier 406. Forward end portions of actuating links 454 are connected by pivot pins 456 to each of the levers 450, rearward ends of the links 454 being mounted on studs 458 extending from upturned ends of a crossbar 460 that is secured to upwardly extending arms 462 (Figs. l and 2) of a lever having another arm 464. The lever is pivoted on a shaft 466 (Fig. 2) carried by brackets 468 respectively aixed to the side brackets 18, 20 and is operated by linkage connecting it with the hand lever 440 as will now be explained. A link 470 connects the arm 464 with a third arm 472 of the lever 422, 424. The lower end of the arm 472 is connected by a link 474 to an arm 476 (Fig. 2) aixed on a cross shaft 478 journaled in bosses formed on the intermediate bracket 48. An arm 480 also fast on the shaft 478 .is pivotally connected to the lower end of a link 482, the upper end of which is connected to an arm 484 of the hand lever 440 which is pivotally mounted on a cross shaft 486 supported by the side bracket 20. Accordingly as the wiper carrier 406 is advanced relatively to the t'oe band carrier bracket 308 by forward swinging movement of the hand lever 440, the links 454 are moved forwardly more Vrapidly than the wipe-r carrier. They thus swing the levers 450 to impart closing movement to the heated wipers 34 as 'they wipe the stock, tensioned heightwise at the toe end of the shoe, inwardly over the margin of the insole on the shoe bottom.
In order conveniently to effect withdrawal of Athe holddown 28 from the path of overwiping movement of the heated wipers, mechanism now to be described is ernployed, it being noted that the holddown normally remains in position to sustain marginal portions of the insole against distortion until the wipers have made their 'initial inward wiping movement over the insole edge. Fulcrumed `on the pin 185 (Fig. 4) is a rearwardly extending link 490 having a slot 492. A pin 494 extending through this slot is carried by the split lower end of an arm 496 which is secured at its upper end on the shaft 370. A stop screw 498 adjustably threaded into the link 490 projects into the slot 492 and is eugageable with the pin 494 upon clockwise movement of the arm 496 as seen in Fig. 4. Forward movement of the hand lever 440 acting through the lever 422, 424 to rotate the shaft 370 clockwise accordingly swings the arm 496 to cause engagement of the pin 494 with the screw 498 to shift the link 490 to the left (as seen `in Fig. 4) at the proper instant to disengage the plate 184 from the plate 192 whereupon the springs 84, 108 and the treadle spring 138 (Fig. l) are effective to withdraw the holddown 28 to its inactive position shown in Fig. 1.
As the heated wipers are further advanced to `close and wipe the marginal portion of the upper inwardly over the insole they are forced beneath the upper spreader-retarder 32 which yields upwardly against the resistance of the spring 292 to maintain control over the stock. In order to facilitate formation of a well-defined feather edge in the upper at the edge of the insole, means is provided for causing the wipers to be lowered somewhat after crossing the insole edge to apply increased bedding pressure. Thus for this purpose the front end of the wiper carrier 406 is depressed during its advance by a lowering of the arms 430 which are fulorumed respectively on eccentrics 500 formed on the shaft 432, this shaft being caused suitably to rotate during operation of the hand lever 440 by mechanism now to be explained. Aflixed on the shaft 432 is an arm 502 (Fig. 2) which is connected by a link 504 carrying a stud 506 with an arm 508 of a lever fulcrurned on the cross shaft 382 and having a second arm 510. For a reason later to be stated the stud S06 is adjustably secured in an arcuate slot S12 in the arm 508. A cam roll 514 carried by the arm 510 rides in a cam track 516 formed in a member 518 pivoted on a pin 520 on a carrier 522 that is freely rotatable on the shaft 478. Portions a` and b of the cam track are at certain times concentric with the axis of the shaft 478 and are separated by a portion c. By means of a pin 524 an arm 526 is pivoted 0n an arm 528 of the carrier 522. A spring 530 connecting the latter with the arm 526 may urge it clockwise, as seen in Fig. 2, to cause a latch 532 on that arm to engage a catch plate 534 secured to the member 518 and thus prevent the member from swinging clockwise on the pin 520. The latch 532 may be held clear of the plate 534 against the influence of the spring 530, depending on the position of an operating arm 536 affixed on the shaft 478 as controlled (through linkage above described) by operating movements of the hand lever 440. The arm 536 is provided with opposite faces 538, 540 arranged to engage oppositely disposed stop faces of an abutment 542 formed on the member 518. Accordingly, when the hand lever 440 is in its initial and most rearward position, as indicated in Fig. 2, a stop 543 on the operating arm 536 engages the plate S32 to hold it clear of the plate 534, the face 540 engages the abutment 542, the roll 514 lies above the pin 520 in the cam portion a, and a spring 544 connecting the frame with a projection 546 of the lever 508, 510 urges the latter clockwise about the shaft 382. Consequently initial reaction of Vthe roll 514 on the member V518 urges the vlatter counterclockwise vabout the pin S20 'to the extent determined by engagement of a face 548 on the member 518 with a face on the carrier 522. As the hand lever 440 is swung 'forward to advance and close the wipe-rs, the operating arm 536 is swung clockwise (as seen in Fig. 2) relatively to the carrier 522 to cause the face S38 to engage the abutment 542 and thus allows the latch arm 526 to swing clockwise sufficiently to effect latching of the plate 532 with the plate '534. Upon continued forward movement of the hand lever, and just 'after the wiping edges ofthe 'wipers 'have crossed the edge of'the insole, the portion c of the cam track acts on the cam roll 514 to move the lever 508, 510 counterclockwise as seen in Fig. 2. There results a similar movement of the arm S62 and hence of its shaft 432, and to an extent adjustably determined by the location of the stud S06 along the slot 412. This movement of the shaft 432 acts through its eccentrics 566 to cause the wipers to dip and thereby apply the desired increase in pressure onthe lasting margin as the overwiping movement is completed.
In order to prevent the wipers from detrimentally dragging on the overwiped lasting margin when they are retracted by rearward movement of the hand lever 440, the operating arm 536 is suiciently swung counterclockwise (as seen in Fig. 2) by such movement of the lever to cause the face 540 to engage the abutment 542.
During the relative movement of the arm 536 land the carrier 522 the stop screw 543 depresses the plate 532 to unlatch it from the plate 534. Thereupon the cam member 518 rocks clockwise (as seen in Fig. 2) about the pin 520 under the inuence of the spring 544 until a stop face 550 of the member engages the carrier 522. Since the cam roll S14 then lies in the portion b of the cam track this rocking movement of the member 518 allows the lever 508, 510 to swing clockwise (as seen in Fig. 2) about the shaft 382 promptly to relieve the wipers from applying pressure on the shoe bottom. Upon completion of rearward movement of the hand lever 440 the member 51S is returned to its initial position shown in Fig. 2, the roll 514 again acting on the cam track 516 to determine the initial position of the member 518 relatively to the carrier 522.
As described above, during the course of inward wiping movement of the wipers under the control of the hand lever 44@ the latch plate 184 (Fig. 4) released the plate 192 to allow the holddown 28 and the holddown supporting post 96 automatically to be raised to an inoperative position, the post 96 together with the restcarrying post 42 having been previously locked against heightwise movement as a result of operating the jacking treadle 130. In order to prevent the rest carrying post 42 from being released for upward movement at this stage of the lasting, an arm 554 (Fig. 8) having a cam face 556 is pivoted on a shaft S58 secured in the bracket 48. A link 560 (Figs. 2 `and S) pivotally connects the arm 424 with the arm 554. movement of the arm 424 during advance of the wipers causes the face S56 to ride over a roll 562 carried on the pin 1619 and thereby prevents the bell crank lever 156 from swinging counterclockwise (as seen in Fig. 8). The locking lever 140 is thus held in effective locking position on the post 42 until the wipers are retracted from the shoe when the arm 424 is swung counterclockwise.
Means is provided whereby, if the operator is not satisfied with the manner in which he has jacked a shoe in the machine, the operator may release the latch 184 with respect to the post 96 and thereby the locking means for the post 42 without the necessity of advancing the wipers by operation of the hand lever 440. For this purpose a knee pad 564 is provided (Figs. 1 and 12) which is secured to a bar 566 adjustably secured to one arm 568 of a bell crank lever 570. This lever is fulcrumed on a pin 572 carried by a bracket 574 secured to the intermediate bracket 48. The lever 570 is pivotally connected by means of a pin 576 to one end of a link 578, the other end of the link being connected by a pivot pin 580 (Figs. l, 4 and l2) to an 'arm 582 secured to a cross shaft 584. The shaft 584 is journaled in a bracket S86 secured to the right-hand side bracket 20. Secured to the cross shaft 584 is an upwardly extending arm 588 having an upper end portion biturcated to embrace the link 490 and yarranged to engage a block S90 adjustably secured to a slotted portion of the link 490. A lug 592 (Fig. l2) on the lever S70 limits clockwise movement of the latter upon engagement with a pin i594 in the bracket 574. Displacement of the knee pad Accordingly, clockwise Y' to the right, as seen from the front of the machine,
swings the arni 588 counterclockwise as seen in Fig. 4 to engage the block 590 and to move the link 490 rearwardly. Such movement of the link releases the latch plate 184 from the plate 192 and permits the post 96 to rise and accordingly causes the locking lever to release the rest carrying post 42.
Briey to review a cycle of operations of the machine, the operator initially makes room for easy insertion of a shoe to be lasted by moving the heel rest 202 forwardly while he places the upper at the toe end of the shoe in abutment with the spreader-retarder 32 (Fig. 13). After allowing the heel rest, as effected by the springs 200, yieldingly to clamp the shoe in cooperation with the spreaderretarder and thus position the shoe lengthwise with the toe on the toe rest 26, the holddown 28 is swung over the shoe bottom by means of the handle 98, as indicated in Fig. 5. Next, the holddown is lowered and caused to clamp the shoe against the toe rest pad 38 by depressing the jacking treadle 130. As above explained this treadle may be released, the holddown carrying post 96 and toe rest carrying post 42 then being automatically locked with the shoe held in position to be operated upon and fixed against heightwise movement. This treadle action also automatically assures locking of the heel rest to prevent heelward displacement of the shoe during the lasting operation, the rod 178 and the arm 238 being actuated by the post 96 and operating the pawl 244 to hold the segment 248 against pivotal movement.
With the shoe satisfactorily jacked, and in order preliminarily to position the marginal stock to be lasted, the operator manipulates the spreader-retarder 32 by means of the hand lever 250 as hereinbefore explained. Thus rearward swinging of the lever 250 raises the spreaderretarder 32 from its gaging position and moves it above the erect portions of the lasting margin. Further rearward movement of the lever 250 to interengage the latch plates 296, 302 moves the spreader heelward. Thereafter the spreader is moved down onto the shoe bottom and the margin of the stock is spread outwardly over the toe band 36, as shown in Fig. l, by swinging the lever 250 forwardly, the spreader-retarder snapping downwardly as it passes beyond the insole edge yieldingly to clamp the stock on the toe band. The spreader-retarder has thus traveled in a closed path indicated diagrammatically in Fig. 13. Upwiping by the toe band 36 in cooperation with the spreader-retarder to tension heightwise the stock to be lasted, and heightwise positioning of the retracted and heated wipers are next effected by operating the rocking treadle 374 to actuate the parallel linkages as above described. When the toe band has thus been raised to the adjustable limit of its upward movement the open wipers are at the proper level for commencing inward wiping movement and accordingly the operator, as a tinal step, swings the hand lever 440 forwardly from its initial position shown in Fig. 1 and then rearwardly to complete the lasting. It will be apparent that resulting inward and closing movements of the heated Wipers can cause no marring of any portion of an upper that will be visible in the completed shoe. The advancing wipers are forced beneath the spreader-retarder 32 as it yields upwardly (Fig. l5) and controls the stock to be lasted. The holddown 28 having braced the insole against displacement or distortion until the Wipers 34 cross the insole edge, the forward movement of the hand lever 440, acting through mechanism including the arm 496, the link 490, and the latch 184, permits spring release of the holddown to its inoperative position to clear the way for the wipers. The toe support 26 and the heel rest 30 remain locked during the lasting since upward movement of the post 96 merely raises the pin 174 idly in the slot 176. By means of the operation of the linkage including the arm 536, the cam member 518, the lever 508, 510, the link 504, and the arm 502 during wiper advancing movement of the hand lever 440, the eccentrics 500 cause increased dwell of the wipers in overlasted position as the nature of the cement and the type of stock seem to warrant, the return or rearward movement of the lever 449 restores the wiper controlling parts to their original positions. The pressure of the wipers on the shoe bottom is automatically diminished almost immediately upon such return movement of the hand lever llil as above explained. With the wipers retracted from over the shoe bottom the lasted shoe may be removed from the machine. lt will be appreciated that the invention thus affords a toe lasting machine of compact, reliable organization, and one that is easily as well as economically operated.
