Definitions

  • the invention is not limited in its app plication to machines for use in operating 7 sole, and three-sole shoes.
  • stitchdown shoe is meant, of course, that type of shoe in which the marginal portion of the upper is outturned and secured to a sole the margin of which projects beyond the last bottom.
  • stitchdown shoes may be considered generally as of three kinds, namely, single-sole, two- In the single-sole shoe, the margins of the upper, and lining, it any, are turned outwardly and secured to the margin of a single extension sole.
  • the margins of the upper and lining are turned outwardly and secured to a thin extension sole, the upper and extension sole being then secured to a second extension sole, which is the outsole.
  • the first sole is an insole which does not extend beyond the last bottom and is assembledon the last with the upper; the lining is lasted inwardly over the bottom of the insole; a middle sole or first extension sole is then applied to the last and the outturned upper is secured to the margin of the extension sole; and an outsole of the size of the entension sole is then applied to the shoe and secured to the upper and middle sole.
  • a welt strip is usually applied to the exposed surface of the out-turned margin of the upper and secured by means, usually stitches, which go through the upper and single sole or through the upper and outsole it there is more than one sole.
  • Thermoplastic box toe material is extensively usedin this work and is effective, after cooling, temporarily to hold the lasted upper materials in lasted position until they are permanently secured.
  • An important object of this invention is to provide a machine by the use of which such a welt crease may consistently and uniformly be obtained in stitchdown work.
  • the organization'oi the illustrated machine comprises a pair of end embracing Wipers constructed and arranged for advancing and closing movements and a shoe bottom rest or support located below the wipers and of sufficient extent to support the forepart of a shoe bottom including the margin of the sole of a stitchdown shoe which extends beyond the last bottom, together with power-operated means for effecting relative movement of the wipers and support heighwise of the shoe to eiiect the operation of working the upper over the end of the last and against the projecting margin of the sole.
  • the wipers are arranged to be manually adjusted to adapt them .to embrace the toes of shoes of different sizes and power-operated mean-s is provided to impart to the wipers a predetermined advancing and closing movement to force the lasted upper materials under the edge of the last bottom, or under the insole in work in which the shoe is provided with an insole, said predetermined movement being timed to occur after such relative heightwise movement between the support and the wipers has been effected that the edge of the wipers is in a plane slightly below the edge of the last bottom.
  • the predetermined advancing and closing movements of the wipers are effected positively and these movements are adjustable so that the depth of the crease formed in the upper under the shoe bottom may be varied.
  • novel means is provided for effectively tensioning thetoe portion of the upper during the operation of the wipers in shaping the upper to the last, such means preferably acting at the cornersof the toe and at the sides of the toe.
  • separate clamps at the corners and sides of the toe are provided,
  • means is provided in the illustrated machine for withdrawing the clamps from operative position at that time during said relative heightwise movement when the wipers and the sole are in proximity to each other, the clamps at the corners of the toe being moved bodily lengthwise of the shoe and the clamps at the sides of the toe being swung outwardly away from the shoe to an inoperative position.
  • improved means is provided to hold the last against endwise rearward movement.
  • a member or abutment is provided for engaging the rear end of the shoe and the abutment is operated in conjunction with the relative heightwise movement of the wipers to forceit against the shoe.
  • This force is preferably applied yieldingly and provision is made for setting the position of the abutment, with respect to the means by which force is applied to it, to adapt the machine to handle shoes of various lengths and to insure that substantially the same pressure will be applied to shoes of various sizes irrespective of their length.
  • the abutment is automatically withdrawn from the shoe a sufficient distance to permit convenient removal of the shoe and provision is made to insure that the abutment, when its position is changed for another length of shoe, will be so set with respect to the new length of shoe that this distance between the shoe and upper will always obtain after the shoe is released by the machine.
  • the abutment is preferably arranged to be carried by the sole support and to be adjustable with respect thereto in accordance with the spring and with the swing of the last without affecting theconnection by which the abutment is 0perated to apply endwise pressure to the shoe.

CORPORATION OF JERSEY MACHINE roe OPERATING Uronnun PORTIONS or SHOES Application filed June 17,
ever, the invention is not limited in its app plication to machines for use in operating 7 sole, and three-sole shoes.
upon stitchdown shoes.
By the term stitchdown shoe is meant, of course, that type of shoe in which the marginal portion of the upper is outturned and secured to a sole the margin of which projects beyond the last bottom.
lV'hile the practice of differentmanufacturers varies in detail, stitchdown shoes may be considered generally as of three kinds, namely, single-sole, two- In the single-sole shoe, the margins of the upper, and lining, it any, are turned outwardly and secured to the margin of a single extension sole. In the two-sole shoe, the margins of the upper and lining are turned outwardly and secured to a thin extension sole, the upper and extension sole being then secured to a second extension sole, which is the outsole. In the threesole shoe, the first sole is an insole which does not extend beyond the last bottom and is assembledon the last with the upper; the lining is lasted inwardly over the bottom of the insole; a middle sole or first extension sole is then applied to the last and the outturned upper is secured to the margin of the extension sole; and an outsole of the size of the entension sole is then applied to the shoe and secured to the upper and middle sole. In all of these shoes a welt strip is usually applied to the exposed surface of the out-turned margin of the upper and secured by means, usually stitches, which go through the upper and single sole or through the upper and outsole it there is more than one sole. It is also usual to insert a toe box and counter bet son the upper and lining at the toe and heel respectively, which are treated as parts of the upper materials. The toe box is frequently of material which can be softened prior to the lasting operation and contains cementitious material which, upon harden- 1929. Serial No. 371,493.
ing after lasting, will hold, the upperin lasted position to the projecting margin of the sole. Thermoplastic box toe material is extensively usedin this work and is effective, after cooling, temporarily to hold the lasted upper materials in lasted position until they are permanently secured.
In lasting the toe portions of stitchdown shoes of whatever type, it is particularly desirable not only that the upper-materials be shaped over the toe and into the angle between the side of the last and the projecting margin of the sole, but that theupper at the angle be tucked under the edge of the last or insole so that a definite crease will be formed into which the edge of the welt strip may be forced and which in the finished shoe will give an appearance similar to that of the welt crease of a welt shoe.
An important object of this invention is to provide a machine by the use of which such a welt crease may consistently and uniformly be obtained in stitchdown work.
Other objects of the invention are to provide improved means for effecting the ten sioning of the upper materials in conjunctionwith the working of them into lasted position, to insure that the shoe will be properly positioned and maintained against displacement during the upper shaping operation and, without sacrificing any of the advantages of prior machines for this work such as that disclosed in application Serial No. 244,230, filed January 3, 1928 in the name of Rene E. Duplessis, to provide a machine which will be rapid and effective in operation and which will be more nearly automatic than prior machines for this work. 4
With these and other objects in view, the organization'oi the illustrated machine comprises a pair of end embracing Wipers constructed and arranged for advancing and closing movements and a shoe bottom rest or support located below the wipers and of sufficient extent to support the forepart of a shoe bottom including the margin of the sole of a stitchdown shoe which extends beyond the last bottom, together with power-operated means for effecting relative movement of the wipers and support heighwise of the shoe to eiiect the operation of working the upper over the end of the last and against the projecting margin of the sole. As illustrated, the wipers are arranged to be manually adjusted to adapt them .to embrace the toes of shoes of different sizes and power-operated mean-s is provided to impart to the wipers a predetermined advancing and closing movement to force the lasted upper materials under the edge of the last bottom, or under the insole in work in which the shoe is provided with an insole, said predetermined movement being timed to occur after such relative heightwise movement between the support and the wipers has been effected that the edge of the wipers is in a plane slightly below the edge of the last bottom. As illustrated also, the predetermined advancing and closing movements of the wipers are effected positively and these movements are adjustable so that the depth of the crease formed in the upper under the shoe bottom may be varied.
In the illustrated machine, furthermore, novel means is provided for effectively tensioning thetoe portion of the upper during the operation of the wipers in shaping the upper to the last, such means preferably acting at the cornersof the toe and at the sides of the toe. As illustrated, separate clamps at the corners and sides of the toe are provided,
which clamps are operated during the relative heightwise movement. of the wipers and support to elamp the margin of the upper against the lower surface of the wipers, the upper being progressively withdrawn from between the clamps and wipers during said relative heightwise movement.
In order that the clamps may not interfere with the projecting margin of the sole and withthe pressing of the upper by the wipers against .the projecting margin of the sole, means is provided in the illustrated machine for withdrawing the clamps from operative position at that time during said relative heightwise movement when the wipers and the sole are in proximity to each other, the clamps at the corners of the toe being moved bodily lengthwise of the shoe and the clamps at the sides of the toe being swung outwardly away from the shoe to an inoperative position.
In order that the relative heightwise movement of the wipers and shoe support may be fully effective to work the upper into lasted position and to prevent movement of the shoe and last in response to the advancing movement of the wipers to form the crease, improved means is provided to hold the last against endwise rearward movement. As illustrated, a member or abutment is provided for engaging the rear end of the shoe and the abutment is operated in conjunction with the relative heightwise movement of the wipers to forceit against the shoe. This force is preferably applied yieldingly and provision is made for setting the position of the abutment, with respect to the means by which force is applied to it, to adapt the machine to handle shoes of various lengths and to insure that substantially the same pressure will be applied to shoes of various sizes irrespective of their length. hen the shoe is released from the illustrated machine, the abutment is automatically withdrawn from the shoe a sufficient distance to permit convenient removal of the shoe and provision is made to insure that the abutment, when its position is changed for another length of shoe, will be so set with respect to the new length of shoe that this distance between the shoe and upper will always obtain after the shoe is released by the machine. The abutment is preferably arranged to be carried by the sole support and to be adjustable with respect thereto in accordance with the spring and with the swing of the last without affecting theconnection by which the abutment is 0perated to apply endwise pressure to the shoe.
These and other features of the invention, including various novel constructions and arrangements of parts, will appear more fully from the following detailed description vhen read in connection with the accompanying drawings and will be pointed out in the appended claims.

block to the gear.
The illustrated machine for shaping'uppers over the end portions of stitchdown shoes, and particularly the toe ends of such shoes, comprises a base or frame in which is mounted a main shaft 12. On the shaft 12 are mounted a gear 14 and a cam block 16, there being between the gear 1% and the cam block 16 a suitable form of half-revolution and there being on the right-hand side of the machine a cam block similar to the cam block .16 for imparting movements to the op erating instrumentalities on the right-hand side of the machine. The mechanism at the left-hand side of the machine will be particularly described, it being understood that the mechanism at the right-hand side of the machine is substantially a duplicate of that on the other side, except for reversal of parts, and is arranged for operation on a shoe for the opposite foot, for example a right shoe. As best shown in Fig. l, a stop projection 20 on the clutch between the gear 14 and the cam block 16 engages a stop arm 22, said arm being pivoted at 2 1- and having a forward projection carrying a pin 26 which is slabbed off on its front side. An upright bar 28 has an elongated notch 30 in its upoer end engaging thepin 26 and at its lower end is pivoted at 32 to a treadle 3 1. The length of the notch 30 is such that lost motion between the bar 28 and the pin 26 is permitted during the preliminary depression of the treadle, the notch 80 engaging the pin 26 and lifting the arm 22 from the projection 20 to permit setting of the clutch only during the final depression. After the machine starts. the bar 28 is pushed forwardly by a suitable formationon the cam block 16 to free the notch 30 from the pin 26, allowing the stop arm 22 to drop back intopositi on to stop the machine again after the cam block 16 has made half a revolution.
The clutch and driving mechanism above briefly described may be substantially similar to that disclosed in United States Letters Patent No. 1,674,085, granted June 19, 1928, on application of Ballard and Seely, to which reference may be had for further explanation of this part of the machine.
A bar 36 is forked at its rear end to embrace the shaft 12 upon which it is guided. Pivoted at 38 on the inner sideof the bar 36 is a roll which engages a cam track 40 in the cam block 16 by which the bar is moved lengthwise. At its forward end the bar is pivoted at 42 to the joint of a toggle one link la-of which is pivoted at 16 to a rod 48 upon the upper portion of. which is threaded a nut 50. The rod 48 extends freely into a hole in the top ofa plunger '52 which is mounted for reciprocation in a cylindrical member 5 1, the upward movement of the plunger being limited by a screw 56 extendinginto a slot in the side of the plunger 52. Beneath the plunger is a spring 58 which rests on a support mounted for adjustment to vary the tension of the spring by'turning a conveniently arranged handle 59, as explained in the above-mentioned patent. The other link 60 of the toggle ispivoted to a block 62 (Fig. 4) mounted in a slot 64; in the lower end of a longitudinally movable shaft 66. To confine the block 62 in the slot 6 1 a strap 68 is passed around the end of the post 66 and secured thereto by a bolt 70. Between the upper end of the block 62 and the end of the slot 64 is a space to permit the shaft 66 to be adjusted relatively to the block 62, as will be explained. The shaft 66 is-guided for movement in the frame 10 of the machine in a direction inclined upwardly and rearwardly with respect to the machine and at its upper end has a reduced portion 74 on which is pinned a block 76. On the top of the block 76, which is horizontal, a sole supporting plate 78 is mounted by dowel pins one of which is shown at 80. On the lower end of the block 76 is a screw 81 which engages a boss on the frame and adjustably determines the heightwise position of the block 76 and shoe support 78, such adjustment being permitted by the portion of the slot 6 1 above the block 62. Thus the normal position, heightwise of the shoe, of the plate 78 may be varied for different thicknesses of soles by turning the screw 81. The plate 78 corresponds substantially in size and shape to the forepart of a stitchdown shoe sole includin themarginal extension thereof, and, in order to take care of large variations in shoe sizes, the plate 78 may be lifted off and a larger or smaller plate substituted to correspond to the size of shoe being treated.
In the forward portion of the block 76 is mounted a pin 82 which is held in place by a draw-boltSl. The draw-bolt 84, however, need not be set up tightly enough to prevent turning of the pin 82 but only sufficiently to hold it frictionally against turning 'movement. To the pin 82 is pivoted at 86 a member 88 which can be swung laterally on the pin to correspond to the swing of the last. Through a depending portion 89 of the member 88 is threadeda screw 90 bearing against the block 76 and provided with a hand-wheel 92 which may be turned to vary the angular relation in a vertical plane of the member 88 to the sole support 78, this adjustment being to take care of the spring of the last. The member 88 (Fig. 5) is channeled at 94 to re ceive a sliding member 96 the upper surface of which is formed with rack teeth98. The
slide 96 is channeled on its under side to receive a compression spring 100 which bears at its inner end against the member 88 and at its outer end against the slide 96, the spring tending to hold the slide 96 outwardly against a suitable stop 102.
Arranged to slide on the top of the member 88 is a carriage 104, said carriage having a portion which extends into the channel 94 and is provided with ribs 106 which engage corresponding grooves formed in the upper portions of the side walls of the channel 94, the lower'face of the carriage being arranged just above the surface of the rack teeth 98 and in sliding relation thereto. A plunger 108 is mounted in the carriage 104 for limited movement perpendicularly to the rack bar 98 and has teeth on its lower surface to engage the rack teeth 98 and lock the carriage 104 to the slide 96. The plunger 108 is held depressed by a compression spring 110 the upper portion of which surrounds the stem of a headed pin 112 the head of which frictionally engages a stem 114 arranged for sliding movement through the carriage longitudinally of the shoe. On the inner end of the stem 114 is pivoted at 116 an abutment 118 which is adapted to engage the rear end of the shoe, the abutment 118 preferably having a cover 120 of yielding material to prevent marring of the shoe upper and also having, as shown in Fig. 3, projecting portions 122 which prevent lateral movement of the rear end of the shoe with respect to the abutment 118. Inward movement of the stem 114 with respect to the carriage 104 is limited by a lug 124 on the stem which engages the carriage, and the stem is frictionally held from accidental displacement by friction of the headed pin 112 thereon due to the pressure of the spring 110. In order that the position of the carriage 104 with respect to the rack bar 98 may be changed to accommodate different lengths of shoes, the plunger 108 may be lifted against the tension of the spring 110 to disengage its teeth from the rack teeth 98 by a hand-piece 126 which at its lower end is secured by a pin 128 to the plunger and is guided for vertical movement with respect to the carriage by a headed stud 130 engaging suitable vertical guideways in the carriage 104, a slot 132 in the carriage permitting vertical movement of the pin 128. hen the stem 114 is in its rearward position, it lies over the hand-piece 126 so that the handpiece cannot be lifted to release the teeth of the plunger 108 from the rack bar 98. If, however, the stem 114 is pushed inwardly of the machine, the hand-piece 126 is free to be lifted and the carriage 104 can be placed in any position along the rack teeth 98. In order to locate the abutment 118 in the proper position for operation upon a shoe of given length, the stem 114 is pushed forward, the hand-piece 126 lifted, and the carriage 104 moved outwardly a suflicient distance to admltthe shoe, which is then placed in the machine as shown in Fig. 4. The carriage 104 is then moved inwardly toward the shoe untilto the shoe at a point heightwise of the shoe .50
which is near the plane of the sole. WVhen the carriage 96 is allowed to be moved back by its spring 100, there will, of course, be at the rear of the shoe between the shoe and the abutment a space equal to the amount of relative movement between the abutment and the carriage so that the shoe can be easily removed from the machine, but, since the carriage 104 cannot be reset for a different length of shoe without first pushing the stem 114 inwardly to release the handles 126, it is assured that the space between the shoe and abutment will always obtain when the shoe is released and that the pressure applied to the shoe by the abutment will not be excessive.
For moving the slide 96 to operate the abutment as described, a pulley 136 is mounted on a stud 138 fixed to the slide 96 and occupying a slot 140 in the member 88. The bight of a cable 142 is placed upon the pulley 136, each of the two runs of the cable being passed over an idle pulley 144 mounted on the depending portion 89 of the member 88 near its pivot 86 and the two ends of the cable being held in a clamp 146 which comprises two similar plates grooved to receive the cable and held together by a bolt 148. The clamp 146 is connected to an arm 150 of an angle lever by means of a yieldingly extensible connection which, as illustrated, comprises two identical U-shaped members 152 and 154 which have their ends reversely bent to form hooks. The members 152 and 154 are passed in opposite directions through a compression spring 156, the loop of one being engaged by the bolt 148 and the loopof the other being engaged by a pin 158 passing through the end of the arm 150, which is bifurcated. Also connected to the pin 158 is a treadle rod 160 which passes through the outer portion of the treadle lever 34 (Fig. 1) and has thereon between the treadle and a nut 162 on the end of the rod a compression spring 164 which is still enough to overcome the spring 100. Consequently, when the treadle is depressed the slide 96 will be moved toward the shoe through the spring 164. The arm 150 above mentioned is part of an angle lever the other arm 166 of which (Fig. 4) is pivoted by a pin 168 to the shaft 66. A link theinitlal depression of the treadle described,
the angle lever 150, 166 will turn on the pin 168 as a fulcrum, the pin 176 then moving downwardly in the slots 17 4 and the carriage 104 will be moved toward the shoe to take up the lost motion between it and the abutment 118, the portion of the arm 166 at the rear of the pin 168 of coursemoving upwardly.
Toeach side of the rear end of the arm 166 is pivoted at 178a sleeve 180 through which passes a rod 182 having stop nuts 184 on its lower end. On each rod 182 is threaded a nut 186 forming an adjustable stop between which and the sleeve 180 is a compression spring 188. The upper ends of the rods 182, 182 pass through a horseshoe-shaped plate 190 (Fig. 8) and each rod is threaded into an upright member 192 to which is so cured at- 194 a clamp 196 having a laterally extending portion directed toward the shoe and arranged to be under the projecting margin of the upper and to be over the projecting margin of the sole. The clamps 196, 196 are arranged at the corners of the toe and by upward movement of the members 192 are operated to clamp the outwardly extending margin of the shoe upper at the corners of the toe against the lower surface of toe embracing wipers 200,202 which, as shown in Figs. 4 and 8, embrace the shoe toe in a plane located above the shoe bottom. The lower position of the upper clamps is adjustable by means of a screw 204 threaded through the horseshoe-shaped plate 190 and engaginga flat surface on the frame 10, the adjustment being such that the lateral projections of the clamps 196 are just above the projecting margin of the sole. The members 192 (Figs. 3 and 8) are guided on their'inner faces by fiat surfaces formed on projections 206 of the block 76 carrying the shoe support and on their outer faces are guided by rearwardly projecting portions 208 of plates 210 fixedly secured to opposite sides of the block -7 6. This construction enables the members 192 to be moved toward and from the shoe lengthwise thereof to carry the corner clamps 196, 196 intoand out of upper clamping position, such movement being permitted, of course, by swinging movement of the rods 182 about their pivot 178- to the lever arm 166. Each of the plates 210 is provided with two ears 212 2) in which is mounted a vertical stem 214 (Fig. 8) the lower end of which rests ou the horseshoe-shaped plate 190 and the upper end of which has an offset portion2-16 to which a side clamp 218 is secured at 220. By turning movement of the stems 214, therefore, the clamps 218 may be swung laterally of the shoe toe into and out of position to clamp the upper against the wipers In order to swing the side clamps 218, 218 outwardly of the shoe and to move the corner clamps 196, 196 bodily lengthwise of the shoe, the following mechanism is provided: On
each of the stems 214 is an arm 222 to which is pivoted at 224 a block 225 having ears 226 to which is pivoted at 227 a link comprising two members 228, 229 which are threaded together so that lengthwise adjustment of the link may be effected. The rear end ofthe link 228, 229 is pivoted at 230 to a member 232 fixed to a horizontalrod'234, this rod passing through holes formed'inth'e members 192 which carry the corner clamps" 196. The central portion of the rod 234 passes througha yoke 236 intowhich is threaded a link 238 i (Fig. 4) the rear end of the link being pivoted at 240 to a lever 242 fulcrumedat 244 on the machine frame and pivotally connected at its lower end to the toggle actuating bar 86. In order that the rectilinear movement of the bar 36 may be utilized to impart move-- ment to the lever 242, a forked member 246 is bivoted to an ear 248 on the bar 36- and has a stem 250 which slides freely in a hole bored lengthwise of the lever 242. By the mechanism described it will be apparent that forward movement of the bar 36 will move the corner clamps 196 away fromthe shoe and will swing the side clamps 218 outwardly about the stems 214 away from the sides of the shoe, the clamps being thus moved outof position to clamp the upper against the wipers and their lateral extensions being consequently removed from position over the projecting margin of the sole so that the wipers and the shoe support may be relatively operated to press the outturned margin of the upper and the projecting margin of the sole together. 1
The wipers 200, 202 (Fig. 3) which embrace the end of the shoe are'each. detachably secured at251 to a wiper carrier 252.
Each wiper carrier is provided with two arcuate'slots 254 which engage rolls 256 mounted on fixed axes in the wiper head 258', the slots 254 being s0 formed and arranged that when the wiper carriers are moved toward. the
shoe the wipers 200,202 will be advanced and cover-plate 261 and the head 258 which ex tend inwardly over the ends of the wipers and sustain them against upward pressure.
Two separate means are provided for effecting advancing and closing movementsof the wipers, one being a manually effectedad j ustment for the purpose of setting the wipers .130
so that they will correspond to the shape and size of the toe of ashoe being lasted and the other being a power-effected movement of predetermined extent to cause the wipers to tuck the fold of the outturned upper under the edge of the last. Each wiper carrier 252 is connected at 262 to a link 264 the rear ends of the links 264 being pivoted at 266 to a cross-bar 268 having a rearwardly extending threaded stem 270. The stem 270 is threaded into a sleeve 272 which is mounted for rotating movement in a boss 274 formed on tire wiper head 258 and is held from rearward movement by a flange 276. The rear end of the sleeve 272 is formed as a threaded stem 278 on which is threaded a hand-wheel 280, the hand-wheel being normally fixed to the stem by means of a set-nut 282. Between the ,hand-wheel and the boss 274 is a compression spring 284. It will be seen that by turning the hand-wheel 280 the sleeve 272 may be turned and the bar 268 moved forwardly or rearwardly to adjust the wiper carriers and hence the setting of the wipers 200, 202;
"that is, the extent to which they are initial- 1y advanced and closed, or retracted and opened, may be varied. The power-effected advancing and closing movement of the wipers is caused by pressure applied to the rear end of the stem 278 by an adjustable screw 286 threaded through the upper end of a lever 288 (Fig. 4) fulcrumed at 244 and having a roll 290 on its depending arm arranged to engage an edge cam 292 on the cam block ;16. The screw 286 affords means for varying the effective upper tucking or crease forming movement of the wipers. The timing oft-he cam 292, as shown in Fig. 9, is such that the wipers are advanced and closed. positively a predetermined amount after initial upward pressure has been applied to the work support 78 by the cam 40, acting through the toggle 44, 60,-to press the outturned margin of the upper and the projecting margin of the "sole against'the wipers and prior to the final pressure applied by the cam 40 to the work support.
In order to clamp the upper to the last in.
the vicinity of the tip line to prevent undue movement of the upper relatively to the last by the tension applied to the upper. such as might result in forward bowing of the tip seam, a toe clamp 294 is provided, the clamp being preferably padded with yielding material 296 and provided with a cover 298 of a washer engaging the sleeve 302. Rotation of the stemis prevented by a screw 312having a flattened end engaging a groove in the stem 300. The position of the clamp 294 longitudinally of the shoe may be varied by loosening the bolt 304, turning the sleeve 302 on the bolt as an axis and tightening the bolt. In the drawings the machine is illustrated as operating upon a stitchdown shoe which, when completed, will have three soles. It is to be understood, however, that the machine is equally well adapted for operating upon shoes of any of the three kinds hereinbefore referred to or variations thereof. At the time when the toe lasting operation is performed, the shoe comprises an insole a and a middle or first extension sole 6 secured to a last 0 on which are assembled an upper d and lining 0, the lining 6 having been wiped, in and secured to the insole by cement prior to the attachment to the last of the middle sole b.
It is also a usual practice in some work to pull over both the upper and the lining and secure them temporarily to the insole by partially driven tacks before the middle sole is applied, the shoe being allowed to remain in this condition until the upper has set to the last. The upper is then released by pulling the tacks, the lining secured to the in-: sole and the middle sole applied, the shoe being in this condition when it comes to the operator of the illustrated machine. It is also usual to insert a heated thermoplastic toe box f between the upperand lining just prior to the introduction of a shoe into the machine.
In the operation of the machine the op erato'rwill slide forwardly the stem 114 of the abutment 118 to release the hand-piece 126, will raise the plunger 108 and move the carriage 104 rearwardly far enough to admit the shoe, that is, of course, unless the carriage is alread in that position. The forepart of the shoe bottom is then placed upon the support 78 with the end. of the shoe against the wipers 200, 202, which are adjusted if neces- T sary by means of the hand-wheel 280 to ad- Vance and close the wipers or to retract and open them until they fit the size of toe being operated upon. The carriage 104 will now be I released by lifting the hand-piece 126 and moved toward the shoe until the abutment 118 engages the shoe.
when it is raised, the operator cannotmove the carriage toward the shoe far enough to take up the lost motion provided between the stem 114 and the carriage. If the operator the shoe as it should, he will swing the mem- Since the stem 114 of the abutment engages the hand-piece v126 her 88 on the pin 82 against the friction of the draw-bolt until the abutment is properly located so that the rear end of the shoe will engage between the projections 122 on the abutment. This lateral swinging move J of the cable 142 to lengthen as the other run shortens. Upon contact of the abutment with the shoe, the hand-piece 126 is released and the carriage 124 becomes locked to the slide 96 by the action of the spring 110 on the plunger 108. e
If the operator finds that the carriage 104 is not adjusted heightwise in accordance with the spring of the last properly to engage the rear end of the sole while tile forepart is in flat engagement with the support 7 8, he will operate the hand-wheel 92 to effect such adjustments, the member 88 then turning on its pivot 86 to the pin 82. This movement, however, does not materially affect the tension of the cable 142 because the idle pulleys 144 are pivoted near the pivot 86 of the mem-,
ber 88.
To move the slide 96 and the carriage 104 1 toward the shoe, the operator depresses the treadle 24 which acts through the rod 160 and the cable 142 to move the slide 96 and the carriage toward the shoe. During this movement the carriage 104 will move relatively to the abutment to take up the lost motion between the abutment and the carriage and to bring the projection 184 into position to engage the abutment 118 at a point heightwise of the shoe which is below the center of the rear end of the last, pressure at this point being effective to hold the shoe against the wipers at the toe. During this movement of the carriage 104 the lever 150, 166 has been turning on the pin 168 as av fulcrum while the pin 17 6 has moved downwardly in the slots 17 4 of the link 170. This movement of the angle lever, acting through the springs 188, has lifted the clamps 196, 218 sufliciently to engage the upper and press it lightly against the lower face of the wipers 200, 202. If the operator finds, upon inspection of the shoe, that the upper materials have not been properly positioned between the wipers and the clamps, or wishes to change the adjustment of the machine for any reason, the treadle may be released and the operation repeated. The manual operation performed by the treadle as described puts very little burden upon the operator since in this operation only the tension of the light spring 100 has to be overcome in moving the carriage 104 and the clamps 196,218 raised into position toengage the upperwithout applying substantial pressure to the clamps through the springs 188 or to the abutment 118 through the spring 152. lVhen the parts have been moved by the treadle into these positions, however, the added resistance of the springs 188 to movement of the treadle causes the spring 164 to yield slightly and the clutch to'be tripped since the lift the stop arm 22 and trip initial movement of the treadle 34 has taken up the lost motion provided by the notch 30, so that the final depression of the treadle will the clutch, power rotation of the cam block 16 then taking place. During the power operation-of the machine, the bar 36 will be moved longitudinally forwardy of the machine by the action of the cam track 40, causing the toggle 44, to be straightened. As the toggle is straightened, the space 7 2 above the block 62 will be first taken up and then the shaft 66 will begin to move upwardly. The pin 17 6, having been brought by the operation of the treadle to the bottom of the slot 174, now becomes the fulcrum of the angle lever 150, 166, and, as the shaft 66 carrying the shoe supports 78, 104 moves upwardly under power. to effect relative heightwise Wiping movement between the shoe and the wipers 200, 202, the tension of the springs 188 will be rapidly increased since the rear end of the lever 166 moves faster than its point of connection 168 to the shaft 66 to cause the upper to be clamped against the wipers more and more firmly as the wiping operation progresses. At the same time the arm 150 has moved downwardly about the pin'176 as a center to cause the abutment 118 to be pressed yieldingly against the rear end of the shoe through the spring 156.
The faces of the. clamps 196, 218 which engage the upper are preferably transversely undulated or corrugated, asshown in Fig. 8, to provide suflicient friction between the clamps and the wipers so that the upper will not slip until the desired tension has been applied thereto and yet will not hold the upper so that it cannot slip or to such an extent that there is danger of its being damaged. The side clamps 218 are substantially opposite the outer ends of the wipers and the wipers are relatively long, so that the tension produced by the clamps 218 will cause the upper to be drawn down tightly to the last just at the rear of the tip line. The clamps 196, be-
- ing placed at the corners of the toe, effect longitudinal tensioning of the upper at each side of the longitudinal median line along which theupper was previously stretched in the pulling-over operation, if that operation was employed, and effect tensioning, of those portions of the toe'of the upper which re ceive less tension during the pulling-over operation, that is, the portions which, when theshoe was in pulled over condition, constituted the ears or folds of the upper formed in that operation at the corners of the toe.
During the upwardmovement of the shoe support 78 the upper is clamped to the last in the vicinity of the tip line by upward pressure of the shoe against the yielding abutment 294. This clamping of the upper to the last during the wiping operation prevents the tip wvardly and upwardly so that during the upward movement of the shaft there is a;
component of movement of the shoe support and shoe toward the wipers to enhance their 4 wiping action. During the early part of the wiping operation, the lateral extensions of the clamps 196, 218 are positioned over the projecting margin of the middle sole 6 with their ends close to the last and hence must be a moved outwardly of the shoe to permit the projecting margin of the sole to be pressed against the outturned margin of the upper. This is effected by the described movement of the bar 36 which operates the lever 242 to retract the corner clamps 196 and to swing the side clamps 218 outwardly so that by the time the first rise of the shoe-support-pressure-cam 40 is effective, as shown in Fig. 6, to apply preliminary pressure to the sole and upper flange between the support 7 8 and the wipers 200, 202, the clamps will be suiliciently withdrawn to clear the margin of the sole. During the movement of the clamps outwardly of the shoe, less and less of the area of their clamping faces is in engagement with the upper-butat the same time the upward pressure on the clamps progressively increases so that the effective clamping action of the clamps is substantially constant during that portion of the upward movement of the suplustrated in Fig. 7, the upper is tucked at the angle between the side of the last and the projecting margin of the sole under the last bottom and against the edge face of the insole F). Since the advancing and closing movements of the wipers are positive and predetermined and the. shoe is held against rearward endwise movement by the abutment 118 as well as by the toe clamp 294, this creasing of the upper or carrying of the fold of the upper under the last bottom will be consistently and uniformly effected independently of the operator. If, for any reason such as faulty ad ustment of the mach ne, the wipers should engage the side of the as ins ea 0 ){ISSlD in e r l,- l t t d f j g r d r the last bo tom during their predetermined power operation, the shoe can be forced rearwardly against the tension of the abutment spring 156: and breakage of the machine will consequently be avoided. hen, in the case of a three-sole shoe,as illustrated, the wipers are operated against the edge of the insole, the insole will yield sufiiciently in response to the positive power operation of the wipers to permit the upper to be carried under the last bottom to the required extent. Of course, under conditions where the margin of the sole is beveled or shoulder channeled, or where the margin of the last bottom is beveled, the operation of the machine will be equally as effective as under the more diflicult' conditions described. v
While the wipers are held in by the wiper cam 292, the second rise of the shoe-supportpressure-cam operates the toggle 44, to apply final and maximum pressure to the shoe support to ress the outturned flange of the upper and t 1e projecting margin of the sole more firmly against the wipers and to set the crease formed in the upper The cam block 16 having now made a half revoution, the machine stops with the shoe held under pressure. he amount of upward pressure of the shoe support is, of course, determinod by the amount of compression of the spring 58, and the point in the cycle of the machine when the spring is brought into action may be varied to suitdifferent conditions of work by adjustment of the nut 50 on the plunger 48, the initial tension of the spring 58 being controlled by turning the handle 59.
The shoe remains under pressure until the operator has similarly treated another shoe, for example a shoe for the opposite foot, by the mechanism at the right-hand side of the machine. su 'iposing a thermoplastic toe box to have been inserted between the upper and lining prior to the placing of the shoe in the machine, the toe boxwill, of course, have been shaped to the last with the upper and its margin laid against the projecting margin of the sole. While the shoe remains in the machine under pressure, the hot cementing materials with which the toe box is saturated have time to cool and the pressure exerted causes some of the materials to be squeezed out of the toe box and to cause adhesion of the toe box to the extension sole and to the upper so that when the shoe, after cooling, is released from the machine, the materials remain in lasted condition and the shoe is ready for the usual subsequent operations of attaching the upper to the extension sole by stitches or staples and for the application of an outsole and welt, the latter being placed snugly in the crease provided by the action of the wipers about the toe of the shoe, and the welt, upper, middle sole and outsole being secured together by stitches.
In order to release the shoe the operator again depresses the. treadle 34, whereupon the parts are restored to initial position, the abutment 118 being pushed outwardly by the spring 100 acting on the slide 96 and therefore opening up a space at the lot rear end of the shoe equal to the amount of lost motion between the abutment 118 and the carriage 104. Thus ample space is provided for the removal of the shoe and for the roduction of another shoe of the same without any ad ustments being made. wt course if the next shoe to be placed in the machine is substantially larger orbination of end embracing wipers constructed and arranged for advancing and closing movements, a shoe support adapted to support the projecting margin of a sole upon the last-Y 11 cans for efi'ectin relative movement of the wipers and the support heightwise of the shoe to shape the upper to the last, and. nea-ns operative to effect advancing and closing movements of the wipers, said lastn med means being constructed and arranged to initiate said advancing and closing movements substantially at the termination of said relative heightwise movement to force the upper in the angle between the side of the last and the projecting margin of the sole under the last bottom while the outturned margin of the upper lies against the projecting margin of the sole.
