J ., a corporation of New Jersey 1 Application January 27, 1945, Serial No. 574,355 7 Claims. (01. 12-12) This invention relates to lasting machines, and is herein illustrated as applied to a machine con structed generally as disclosed in United States Letters Patent No. 1,843,232, granted on February 2, 1932, on an application of B. Jorgensen’s, but modi?ed in certain respects as further disclosed especially in Letters Patent No. 2,026,539, granted on January 7, 1936, and in Letters Patent No. 2,075,852, granted on April 6, 1937, on other applications of B. Jorgensen’s. Machines of that character are frequently used, as herein shown, for lasting tennis shoes or the like which are commonly made on metal lasts and in which the uppers are secured to in soles by adhesion. It is to be understood, however, that the invention is not limited to the manufacture of shoes of that kind or, in some aspects, to machine organizations such as dis closed in the above-mentioned Letters Patent. A machine such as that to which the invention - is herein shown as applied is provided with toe lasting means including a gripper which is closed by a treadle on the margin of the toe end of the upper prior to the starting of the power operation of the machine and serves thereafter to pull the upper in response to downward movement of the last effected by pressure applied to an insole on the last. The last with the upper and the insole thereon is mounted on a toe rest and on a heel _ 2 . machine after the closing of the gripper on the toe end of the upper by the treadle. In order to save time and thus to increase the output of the machine, and also to avoid such objections as there may sometimes be to, the use of the knee for releasing the heel carriage, especially if the op erator is a Woman, the construction herein shown is such that the treadle which is used to close the toe gripper is used also to release the heel car riage. For this purpose there is provided a lever arranged to act on the above-mentioned plunger and a lost-motion connection between this lever and the treadle for operating the lever by further movement of the treadle after the closing of the toe gripper, the gripper-closing mechanism being so constructed as to permit such further move ment of the treadle. By what may be, there fore, a practically continuous movement of the treadle, the operator ?rst closes the toe gripper and then releases the heel carriage, thus saving a substantial amount of time as compared with previous practice as well as eliminating the need for use of. the knee. The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more par ticularly described with-reference to the accom panying drawings and thereafter pointed out in the claims. . Y - r . end support which are movable downwardly with 30 In the drawings, ~ it; and also movable downwardly with the heel Fig. 1 is a view mainly in front elevation of the end support is a member herein termed a heel greater portion of the machine in which the in carriage which is provided with a heel band for vention is herein shown as embodied, with. the clamping the upper against the last about its heel parts as they appear after the toe gripper has end and, if the heel end of the shoe is to be lasted 3 On been closed and the heel carriage released prior by the machine, with wipers for wiping the mar gin of that end of the upper inwardly over the in sole. The heel carriage is held initially retracted lengthwise of the shoe by a latch which is moved by the operator to release it prior to the starting 40 of the power operation of the machine, Where— upon a spring acting on the carriage moves it to a de?nitely determined position to carry the heel band toward the shoe. In response to the move to the starting of the machine; 7 , Fig. 2 is a plan view on a larger scale ofthe toe-lasting mechanism, with the parts in the same positions as in Fig. 1 but with the shoe omitted; , ~ Fig. 3 is a section, also on an enlarged scale, on the line IlI—HI of Fig. 1; . Fig. 4 is an enlarged view in front elevation of a portion of the structure shown in Fig. 1; ment of the carriage the heel-end support acts 45 Fig. 5 is a section on the line V—-V of Fig. 2, to move the shoe yieldingly a short distance in but showing the toe gripper open; the opposite direction to force it against the heel Fig. 6 is a section substantially on the line band, the band serving as an abutment for posi V'I—VI of Fig. 1; v I tioning the last lengthwise relatively to the ‘toe Fig. 7 is a view in front elevation of a portion lasting means by engagement with the heel end 50 of the heel-end support, with a part broken away of the upper. In the use of such a machine, as constructed heretofore, the heel carriage has been released as above described by pressure of one of the oper ator’s knees against a plunger at the front of the 55 and with one form of last and shoethereonp ; Fig. 8 is a plan view of the heel-end support shown in Fig. 7; and ' > ' Fig. 9 is a section on the line IX-IX of Fig. 8. _' In view of the disclosures in the above-men 2,409,193 3 tioned Letters Patent, only such portions of the machine as it is necessary to refer to for an un derstanding of the invention will be herein par ticularly described. The machine herein shown is constructed for lasting only the toe and heel ends of the shoe, the side-lasting mechanisms sometimes included heretofore in machines .of the illustrative type being omitted. For supporting the last and shoe the machine 10 includes, as heretofore, a slide 2 movable down wardly against the resistance of a spring 4 by pressure applied on the bottom of the heel end of the shoe and a toe rest 6 movable downwardly against the resistance of aspring .8 by pressure 4 to the pins 46 and to brackets 54 fast on the cover plate 34 tend to pull the blocks 38 and. the arms 28 bodily in a direction lengthwise of the shoe away from the toe end of the shoe and also tend to swing the blocks and the arms about the axis of the shaft 32 in the direction to lift the clamp member 26 away from the member 24. Such bodily movement of the blocks and the arms in a direction away from the toe end of the shoe is limited by contact of the shaft 32 with the arms in the slots 36 formed in the latter, and such swinging movement about the axis of the shaft 32 is limited by contact of the tail portions 44 of the arms with the cover plate 34. When the parts are in these initial positions the clamp applied on the bottom of the toe end of .the shoe. 15 member 26 is both lifted and retracted length The shoe and its supporting means are thus moved wise .of the shoe relatively to the member 24, downwardly in the power operation of the ma as shown in Fig. 5, to facilitate the positioning chine by a toe presser-foot l8 and a heel presser of the margin of the toe end of the upper properly foot l2 arranged to engage the toe and heel ends 20 outspread over the member 24. of the insole respectively. The toe presser-foot Movement of the clamp member 26 into clamp ing position is effected by turning the shaft 32 is supported on an arm 14 which by means of a handle [6 is swung forwardly by the operator to carry the toe presser-foot to a position over the toe end of the shoe, whereupon the machine is started and the arm is moved downwardly to carry the presser-foot into engagement with the insole and to impart to the toe end of the shoe its downward movement. As the toe presser-foot is thus moved downwardly the heel presser-foot is swung automatically to a position over the heel end of the shoe and is ‘moved downwardly to depress that end of the shoe. The toe-lasting mechanism includes a toe band is which embraces the upper about the toe end of the last and wipes the upper heightwise of the last in response to the downward movement of the last, and also includes toe-embracing wipers 26 (Fig. 2) which are thereafter operated to wipe the margin of the toe end of the upper inwardly over the insole into position to adhere to the in sole. Further included in the toe-lasting mech in a clockwise direction with reference to Figs. 1 and 5. At the beginning of such movement of 25 the shaft the crank arms 56 act'through the links 48 to move the blocks 38 and the arms 28 length wise of the shoe against the resistance of the springs 52 as far as permitted by engagement of the shaft 32 with the arms in the slots 38 in the 30 arms, thus advancing the clamp member 26 lengthwise of the shoe before it begins its down ward swinging movement. When the lengthwise movements of the arms 28 are stopped by the shaft 32 the links 48 begin to swing the blocks 35 38 and the arms as a unit about the axis of the shaft 32 to carry the clamp member 26 into clamping engagement with the upper, and after this member has engaged the upper the blocks 38 are swung, by further movement of the links, 40 about the rod 36 against the resistance of the springs 42, so that the clamp member is held yieldingly against the upper through these springs. The turning of the shaft 32 is effected by the operator by depression of a treadle 56 (Fig. 1) against the resistance of a spring 58, the anism is a device 22 which serves as a toe gripper and which clamps or grips the marginal portion of the toe end of the upper and applies a pull to the upper in response to the downward move ment of the last. This device, in accordance gen erally with the disclosure of Letters Patent No. 2,075,852, comprises a lower clamp member 24 (Fig. 5) curved to extend around the end of the treadle being connected by a flexible cable 66 to one arm of a lever 62 fast on the shaft 32. Piv otally mounted on the other arm of this lever is toe and having an upper-clamping portion 10- ' cated immediately over the wipers 26, and a co operating clamp member 28 movable relatively to the member 24 to clamp or grip the margin of the upper ‘positioned by the operator between these members. The clamp member 26 is se ~cured to two arms 28 (Fig. 2) which serve as a holder therefor, these arms having therein slots 30 through which extends a shaft 32 supported in bearings on the top of a cover plate 34 posi~ tioned over the wipers, so that the arms may not only swing with the clamp member about the axis of this shaft but may also move lengthwise relatively to the shaft. Extending through the a ?nger 64 controlled by a compression spring 86 (Fig. 2) which tends to swing the portion of the ?nger below the lever toward a lug 68 (Fig. 1) formed on the lever. Initially the ?nger is held by the spring with one side thereof in contact with a lug 19 formed on a plate 12 which is fast 55 on one end of a rockshaft 14 whereby the toe wipers 26 are operated. When the operator de presses the treadle to effect the clamping or grip ping of the toe end of the upper the ?nger 64 is carried upwardly by the lever 62 past the lug ‘I6, whereupon the spring 66 swings the lower end of the ?nger to a position over the top of the lug as shown in'Flg. 1, such swinging movement of the ?nger being limited by contact of the lug 68 on the lever 62 with the end of a screw 16 carried arms 28 is a rod 36 (Fig. 5) on which are piv by the ?nger, The clamp member 26 is thus otally mounted two blocks 38 provided with 65 locked in clamping position by the engagement plungers 40 arranged to bear against shoulders of the lug 16 with the ?nger 64, so that the op on the arms 28 above the rod 36 and controlled erator may remove his foot from the treadle. As by springs 42 in the blocks. These springs tend the rockshaft 14 is turned in the power opera to swing the blocks 38 downwardly about the tion of the machine to operate the wipers, after rod 36 and position the blocks initially in engage the depression of the shoe and the pulling of the ment with the top faces of tail portions 44 of the upper by the toe gripper 22, the lug ‘I0 is carried arms 28. Pivotally connected to pins 46 on’the out from under the ?nger 64, thereby releasing blocks 38 in locations higher than the rod 36 are the lever 62 to permit the return of the clamp links 48 which are also connected to crank arms member 26 to starting position by the springs 56 fast on the shaft 32. Springs 52 connected 75. 5 2,409,193 52. The means thus described for gripping and for applying a pull to the toe end of the upper is constructed mainly as disclosed in the pre viously mentioned Letters Patent No. 2,075,852. -As further described in detail in Letters Patent No, 2,026,539, the previously mentioned vertically movable shoe support slide 2 carries at its upper end a slide ‘I8 (Figs. 1 and 3) mounted for move depending arm I44 the lower end of which is in the path of the horizontally movable heel car riage 96. Accordingly, when the carriage is moved outwardly to its initial position where it is held by the latch I02, as it is automatically near the end of the cycle of operations of the machine through connections including a chain I46 as heretofore, it acts through the arm I44, ments in directions lengthwise of the shoe along the pinion I40 and the crank arm I36 to move guideways 80 on the slide 2. Supported by the 10 the link I34 toward the left (Fig. l) and thereby slide ‘I8 in a vertical shoe-supporting rod 82 hav to move the slide H6 and the shoe support slide ing thereon screw threads engaged by cooperating ‘I8 also to the left. In this manner the shoe is threads of a bevel gear 84 rotatably mounted on the slide 18. The bevel gear 84 is engaged by an other bevel gear 86 fast on a shaft 88 which is rotatable in the slide ‘I8 and extends through a moved lengthwise in a direction away from the heel band I00 which is being moved in the op posite direction away from the shoe by the heel » carriage. Such movement of the link I34 re slot 90 in‘the slide 2 to permit the movements of sults in compression of a spring I48 held between the slide ‘I8 lengthwise of the shoe, the shaft 88 a nut I50 on the link and a plate I52 on the having thereon a hand wheel 92 for turning it to bracket H8. The slide H6 and the connected adjust the rod 82 vertically. Fast on the slide 2 20 slide ‘I8 are held in the positions to which they are two horizontal rods 94 on which a heel car are thus moved by the link I84 by means of a riage 96 is guided for movements lengthwise of latch I 54 pivotally mounted on the bracket H8 the shoe, this heel carriage serving as a support and controlled by a spring I 56, this latch en for heel-lasting mechanism comprising wipers 98 gaging a plate I58 on the slide I I6. Accordingly, (Fig. 1) for wiping the margin of the heel end when the heel carriage 86 is released by the latch of the upper inwardly over the insole and a heel I02 after the next shoe has been mounted on band I00 for embracing and clamping the upper the shoe support, the slide ‘I8 is held in its initial about the heel end of the last. To provide room position by the latch I54 as the heel carriage is for presenting the shoe to the machine the heel toward the shoe by the spring I06. When carriage 96 is held initially retracted lengthwise 30 moved the carriage has nearly reached the position in of the shoe by engagement of a latch I02 (Figs. which it is stopped by the washers I I4, a screw 1 and 4) with a lug I04 on the lower end of the I60 adjustably mounted in the lower end of the carriage, and upon its release by the latch the carriage engages a depending arm I62 of the carriage is moved toward the shoe support by a latch I 54 and causes the latch torelease the slide spring I06 which abuts at its outer end against H6. The spring I48 then acts through the link a bracket I08 fast on the rods 94. The latch I02 I84 to move the shoe support slide ‘I8 toward the is carried by a lever IIO which is pivotally heel carriage until stopped by the engagement of mounted at II2 on the bracket I08 and is swung the heel end of the shoe with the heel bland I00. downwardly to release the heel carriage by means It will thus be seen that the position of each hereinafter described. The movement of the shoe lengthwise relatively to the toe-lasting carriage toward the shoe is limited by its engage ment with washers II4 (Fig. 3) mounted on the rods 94 and abutting against the slide 2. Sub stantially at the time when the carriage engages the washers the shoe is moved lengthwise into engagement with the heel band I00 by a short movement of the slide ‘I8 toward the carriage 86 means is determined by the heel band which acts shaft I20 which carries a bevel gear I 22 in en gagement with another bevel gear I24 fast on a shaft I26 at right angles to the shaft I20 and also . is fast on a rockshaft I10. At its lower end the rod I66 carries a nut I‘I2 arranged to be en as an abutment in contact with the heel-end face of the upper, the heel carriage 96 being always moved to the position determined by the washers H4. The lever IIO which carries the latch I02 is normally held up against the lug I04 on the heel along the guideways 80. For controlling the slide carriage 96 by a. spring I64 connected to a rod 18 there is provided another slide I I6 movable in directions lengthwise of the shoe along a guide (rid I66 which is pivotally connected at its upper end to the lever. The rod extends downwardly way formed on a bracket I I8 which is fast on the through an opening in an arm I68 (Fig. 6) which slide 2. Rotatably mounted in the slide H6 is a rotatably mounted in the slide II 6. The shaft I26 is provided with screw threads engaging co operating threads in a nut I28 mounted in a re cess in the slide ‘I8. On the shaft I20 is a hand wheel I30 for turning it. It will thus be seen that C J by tnrning this hand wheel the slide ‘I8 may be adjusted in directions lengthwise of the shoe rela tively to the slide I I6, and that by the adjusting means the slide ‘I8 and the slide II 6 are held in ?xed relation to each other so as to be mov able as a unit in directions lengthwise of the shoe. Pivotally connected at one end to a pin I32 in the slide I I6 is a link I34 which is pivotally con gaged by the arm I68 to impart downward move ment to the rod and thereby to release the heel carriage from the latch I02 in response to turn ing movement of the rockshaft I70 in a counter clockwise direction with reference to Fig. 6. For imparting such turning movement to the rock shaft there is also fast thereon an arm I14 pro vided with a roll I16 engaged by an inclined face I18 formed on a lug I88 which is part of a bar I82 movable lengthwise in a bracket (not shown). A member I84 extending upwardly from the front end of the bar I82 is engaged by the rear end of a rod I86 slidingly mounted in a bearing in the frame and having fast thereon a plunger nected at its other end to a crank arm I36 (Fig. - I88 movable rearwardly in a boss I90 on the frame against the resistance of a spring I92. In 1) fast on a shaft I38 mounted to turn in the bracket I08. On the hub of this crank arm are gear teeth in engagement with a pinion I40 which is fast on a shaft I42 also mounted to turn in the bracket I08. Fast on the shaft I42 is a response, therefore, to rearward movement of the plunger I88 the heel carriage is released as described, the rearward movement of the barv I82 being effected against the resistance of a. re turn spring I94 acting on a lever I96 provided at’ 2,409,193 its upper end with a ?nger I98 extending into a recess in the bar. The plunger I88 has been provided heretofore with a pad arranged to be engaged by the knee of the operator to e?ect the release of the heel carriage after the depression of the treadle 56 to close the toe gripper 22 on the upper. To save time in the operation of the machine and also to the heel-end portion of the last. The plate 236 is held in different adjusted positions, as may be required by shoes of different sizes, by a bar 242 (Fig. 9) and a screw 244 extending through the bar and threaded in the plate 230. The bar has at its opposite ends upraised portions engaging the opposite side portions of the plate 236 under neath, and when the screw 244 is tightened it acts through the bar to clamp the plate 236 against avoid whatever objections there may sometimes be to the operation of the plunger by the knee, 10 ?anges 246 on the sides of the pltae 238. It will thus be seen that in presenting a shoe to the the machine herein shown is provided, for pur poses of this invention, with means for operating the plunger by further movement of the treadle after the gripping of the toe end of the upper. machine the operator merely places the top of nected at its lower end to the head of a stud sure to the heel end of the upper in the lasting inbefore described. The previously mentioned threaded rod 82 function as when the block is not in use. It will which serves as part of the means for supporting the heel-end portion of the last and shoe has formed on its upper end, as heretofore, a head 224 (Figs. '7 and 8) having therein a guideway 226 engage the upper, it may engage the last itself under some conditions. the heel end of the last on the plate 236 in the position illustrated in Fig. '7, and that when the slide 18 and the parts thereon are moved by the Secured on the boss I96 by a set screw 288 is a .spring I48 toward the heel carriage 96, as here holder 262 on which is pivotally mounted by inbefore described, the shoe is moved lengthwise means of a rod 264 a three-armed lever 266 one toward the heel band I06 and is pressed against arm 208 of which is arranged to engage the front it by the upstanding portion 238 of the plate 236 end of the plunger I88. Another arm 210 of the which thereafter prevents its displacement away 20 lever carries a screw 212 arranged to engage the from the heel band. Accordingly, notwithstand top of the holder 232 when the plunger I88 is in ing the absence of any last pin, the heel band its initial position, this screw serving to limit the is rendered effective to determine the position of forward movement of the plunger. A third arm the last lengthwise relatively to the toe-lasting N4 of the lever is provided with an opening through which extends a rod Zl? pivotally con 25 means and to apply the required clamping pres operation. 2|8 mounted to turn in the treadle 56. Adjust If the machine is used to last a shoe of the ably secured to the rod M6 by a set screw 220 Oxford type mounted on a last of less height at is a block 222 arranged to engage the arm 214 and thus to swing the lever 208 to effect the re 30 its heel~end portion than that shown in Fig. 7, there is preferably utilized a block 248 (Fig. 1) lease of the heel carriage in response to down for engaging and supporting the top face of the ward movement of the treadle. The block 222 heel end of the last, this block being supported is spaced initially far enough from the arm 2M on the plate 230 in the position determined by to permit such downward movement of the trea two pins 256 extending from the block into holes dle as to close the toe gripper on the upper prior 252 (Fig. 8) in the plate. To provide room for to the release of the heel carriage. The release the block 248 the plate 236 has in one end a of the heel carriage is thereafter effected by that curved recess 254 (Fig. 8). The block 248 may further downward movement of the treadle be detached when desired merely by lifting it off which takes place in the swinging of the blocks 38 of the gripper-closing mechanism against the 40 the plate 238. It will be understood that when the block 248 is used the upwardly extending resistance of the springs 42 in the manner here portion 238 of the plate 236 performs the same further be understood that while this upwardly extending portion of the plate 236 will usually As explained in Letters Patent No. 2,026,539, the purpose of movement of the block 228 along the curved guideway 226. when the block has been vicinity of the bottom of its heel end, as more provided as heretofore with a last pin, has been fully disclosed in Letters Patent No. 2,026,539, and to permit the block and the pin to assume posi mounted in this guideway for movement in one tions in accordance with the lateral inclinations direction or the other laterally of the shoe to of the heel ends of right and left lasts when the permit the bottoms of the toe ends of right and lasts are tipped so that the bottoms of their ‘toe left shoes to be properly positioned relatively to ends are positioned in proper relation to the the toe-lasting means is a block 228. This block plane of the toe wipers. In the construction has been provided heretofore with a last pin ar herein shown, notwithstanding the omission of ranged to extend into the spindle hole in the the last pin, provision for such movement of the heel end of the last. To save time in presenting block 228 is retained, so that the block and the 00 a shoe to the machine, in view of the fact that plates 238 and 236 supported thereon similarly such spindle holes are often not uniformly posi may assume different positions for right and tioned in different lasts, there is provided in the left lasts when the lasts are of a style such as construction herein shown, instead of such a to require it. Since each last extends into the last pin, a plate 238 secured by a rivet 232 on recess 240 in the upstanding portion 238 of the the top of the block 228 in a position further plate 236, the block and the plates may be readily determined by a dowel pin 234. Mounted for ad moved in one direction or the other along justing movements along the plate 238 is an the guideway 226 by the engagement of the shoe other plate 236 arranged, as shown in Fig. 'l, or last with the upstanding portion 238 as the for supporting engagement with the top face work is presented to the machine. To limit ad of the heel end of the last and having at one justably their movements in opposite directions, end an upwardly extending portion 238 pro there are provided stops 258 corresponding to vided with a recess 240 with an inclined wall similar stops shown in the last-mentioned Letters curved laterally of the shoe for engagement with Patent, these stops in the construction herein the exterior of the last or of the upper thereon in a location between the toe-end portion and 75 shown being arranged to engage the sides of the extending laterally of the shoe and curved about an axis extending lengthwise of the shoe in the 9 2,409,193. plate 236. The stops are movable as heretofore along a guideway on the head 224 of the rod 82 and are adjusted equal distances toward or from each other by a rod 258 provided with right‘ and left threads and having a knob 26!] thereon for turning it. It will be understood that, if desired, the stops 256 may be so adjusted as to maintain the block 228 and the parts thereon in a central position. In the use of the machine, in so far as it is of interest with reference to the present invention, the operator takes a shoe which, as herein shown, will usually have been already side lasted from its toe-end portion to its heel-end portion and 10 Novel'features relating more particularly to the means herein disclosed for supporting the heel end of the last and for controlling the last with respect to lengthwise movement are claimed in a divisional application, Serial No. 607,813, ?led on July 30, 1945. Having described the invention, what I claim as new and desire to secure by Letters Patent of the United States is: 1. In a lasting machine, a'device for gripping the marginal portion of the toe end of an upper on a last, an operating member movable by the operator to close said device on the upper, an other device for clamping the heel-end portion of mounts it on the toe rest 6 and the heel-end sup the upper against the last, spring means for mov port. If the shoe is one of the Oxford type, as ing said clamping device lengthwise of the last shown in Fig. 1, the block 248 will have been into position thus to clamp the upper, means for mounted on the plate 230 for engagement with holding the clamping device initially retracted the top face of the heel end of the last. Other its clamping position, and mechanism for wise the top of the heel end of the last is engaged 20 from releasing the clamping device to the action of said by the plate 236 as shown in Fig. 7. In thus pre spring means by movement of said operating senting the work the operator positions it with a member. \ portion of the last, and usually also of the upper, 2. In a lasting machine, a device for gripping in the recess 24!} of the upstanding portion 238 the marginal portion of the toe end of an upper of the plate 235 and by moving the heel end of 25 on a last, an operating member movable by the the shoe laterally in one direction or the other, operator to close said device on the upper, an depending upon whether the shoe is a right or a left shoe, shifts the block 223 and the parts there on to a position determined by engagement of one or the other of the stops 256 with the plate 236. In presenting the work the operator also positions the margin of the toe end of the upper outspread between the jaws of the toe gripper 22. After the work has thus been properly pre sented the operator closes the toe gripper on the _ other device for clamping the heel-end portion of the upper against the last, spring means for moving said clamping device lengthwise of the last into position thus to clamp the upper, means for holding the clamping device initially retracted against the resistance of said spring means, and lost-motion mechanism for releasing the clamp ing device to the action’ of said spring means by further movement of said operating member after the gripping of the toe end of the upper. upper by depression of the treadle 56 and by fur ther depression of the treadle thereafter causes 3. In a lasting machine, a device for gripping the block 222 (Fig. 6) to swing the lever 286 in the marginal portion of the toe end of an upper the direction to impart rearward movement to on a last, a treadle movable by the operator the plunger I38. By this means the latch I02 40 to close said device on the upper, another device (Fig. 1) is moved downwardly to release the heel for clamping the heel-end portion of the upper carriage es, whereupon the heel carriage is moved against the last, spring means for moving said by the spring I06 to the position determined by its engagement with the washers H4 (Fig. 3), thus carrying the heel band I00 toward the shoe. Near the end of this movement of the heel car riage the latch I54 is operated to release the slide 18 to the action of the spring I 48 which moves the slide and the parts thereon to carry the shoe to ward the heel band and thus to cause the heel band properly to engage the heel end of the shoe. Such movement is imparted ‘to the shoe by the engagement of the upstanding portion 238 of the plate 236 with the last or with the upper thereon, the operator at this time still holding the shoe down on the heel-end support with his hand. The operator then starts the power operation of the machine by swinging the arm l4 forwardly, and the machine lasts the toe and heel ends of the shoe in a manner which need not be described herein in view of the disclosures of the previous ly mentioned Letters Patent. It will be under stood that after depression of the treadle 56 for the purposes above described the operator re leases it to permit it to be returned to its initial position by the spring 58, the toe gripper being held closed on the upper by the engagement of the lug 19 (Fig. 1) With the finger 64.
