ARTHUR ERNEST JERRAIVI, OF LEICESTER.

MACHINERY COMPANY, OF PATERSON,

JERSEY.

, ENGLAND, ASSIGNOR TO UNITED SHOE NEW JERSEY, A CORPORATION OF NEW LASTING-MACI-IINE.

To all whom it may concern Be it known that I, ARTHUR E. J ERRAM, a subject of the King of England, residing at Leicester, in the county of Leicester, England, have invented certain Improvements in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting machines and has for its object to improve the construction and operation of certain portions of the machine.

A very important feature of the invention consists in an improved shoe support or jack for holding a shoe while it is being lasted or otherwise operated upon. The jack herein shown as embodying this feature of my invention comprises two carriages mounted on a suitable base, which is adapted to be raised and lowered as usual for presenting the shoe carried by the jack to the lasting mechanisms. One of the carriages is provided with a heel pin for engaging the usual pin hole of the last, while the other carriage is provided with arms upon which is supported a wiper or band for engaging and embracing the toe portion of a shoe upon the last. This wiper or band has the usual function of end embracing bands in that it engages and clamps the upper materials about the end portion of the last and holds them in position to be laid over the last bottom by the lasting or crimping jaws. In addition to this function the band has, as herein shown, the function of wiping the upper upwardly about the toe portion of the last. It is therefore known in the art both as a wiper and a band and both names are herein employed without implying any other limitation than the context requires. Operating means is provided for actuating the wiper to cause it to move up along the upper portion of the last for pressing or wiping the upper toward and over the toe of the last and holding it in position to be engaged by the crimping jaws of the lasting mechanism. The supporting arms for the wiper or band are herein shown as levers mounted on fulcra in guides on the carriage, the levers being free to rockiin all directions and Specification of Letters Patent.

Application filed September 26, 1904.

Patented Apr. 9, 1912. Serial No. 225,963.

also to slide longitudinally in the guides. It is to be understood, however, that many of the advantages of the invention may be obtained without employing levers as the supporting arms for the wipers. In the present embodiment of the invention means is provided foradjusting the supporting arms to position their upper ends different distances apart and thereby adapt the band 1 or wiper carried by the arms for shoes of widely different widths. I have provided also a novel connection between the supporting arms and the band or wiper, whereby the band may spread or contract to conform to shoes varying slightly in width without the necessity of adjusting the supporting arms. The supporting arms are arranged to yield together in the same direction transversely of the jack to equalize the shoe embracing pressure at the ends of the band in the event that the last is unsymmetrically shaped at the toe. A further movement of the arms and band together is permitted if required to center an unsymmetrical shoe toe relatively to the crimping aws, if as herein shown, the jaws or the jack head or both have predetermined lateral positions in the machine. With such an arrangement as this the crimping jaws of the lasting mechanism exert greater pressure sometimes upon one than upon the other side of a shoe being lasted. As herein shown, the lower ends of the arms are connected to a common support which is slidingly mounted in the carriage so that the arms may move in company transversely of the jack. Improved means is also provided for supporting the arms so that they may yield to permit the wiper to move longitudinally of the jack while being moved upwardly into position about the toe of the shoe in case the jack is not properly adjusted for the length of the shoe thereon. The machine is also equipped with novel means for angularly adjusting the wiper transversely of the jack to adapt the position of that lasting means laterally to the transverse inclination of the portion of the last with which it cooperates. This adjustment which is made about an axis extending lengthwise of the shoe enables the wiper to be so positioned that its upper edge will be in a plane parallel with the last hot- 7 tom when the wiper has been raised up to the last edge in wiping the upper into lasted position about the end faces of the last ready for the crimping jaws to fold it inwardly over the last bottom. It is advantageous for the wiper to occupy a raised position which is flush and parallel with the last bottom, whatever may be the inclination of the bottom of the particular last in the machine, in order that the lasting means may cooperate with the crimping jaws in forming a square, well-defined edge on the shoe at the edge of the last. The crimping jaws are also arranged for angular movement that they may be positioned in a plane parallel with the plane of the last bottom.

As mechanisms of this class have heretofore been constructed the toe wiper and the means for actuating it into position for. embracing the toe of the shoe have been so arranged that the upper edge of the wiper, as it swung upwardly about its pivotal connection with the supporting arms, exerted on the shoe a wiping action in a direction reverse of that in which it is desired that the wiping action shall occur. This takes place particularly during the latter portion of the upward swing of the wiper and causes the portion of wiper acting on the side ofthe shoe to rub the uppertoward theheel instead of toward the toe, as is desired. In the machine of the present invention this difficulty is obviated by imparting to the wiper a supplemental movement longitudinal of the jack and in a direction away from the heel of the last. As herein shown, this supplemental movement is imparted by means additional to the means which imparts to the wiper its main movement about its pivotal connection with the supportng arms. The two means together cause the wiper to travel during its entire movement into operative position in a direction toward the toe of the last, whereby all the portions of the upper engaged by the wiper are strained in the de sired direction. In the illustrated embodiment of this feature of the invention the crank shaft,which, through the usual crank arm and link, is employed for swinging the wiper upwardly and forwardly about its pivots is provided with an eccentric which is operatively connected with the wiper supporting arms by means which imparts to the supporting arms and wiper a movement toward the toe of the last while the wiper is being swung upwardly. This supplemental movement in addition to the swinging main movement of the wiper results in such an over-compensation for the rearward movement which the upper edge of the wiper would otherwise get that the upper will be wiped toward the toe of the last at all points engaged by the wiper.

Another feature ofthe invention consists in combining with the usual mechanism for raising and lowering the shoe support or jack a means for automatically locking the heel and toe lasting mechanisms in desired position when the jack is raised and for unlocking said lasting mechanisms when the jack is lowered. Preferably this arrangement is such that the lasting mechanisms are securely locked with the desired one in operative position before the jack in rising reaches-the level of said lasting mechanism, whereby all danger is avoided of the lasting mechanisms being in such improper position as to be accidentally engaged by the shoe when the jack is raised.

Other features of the invention, including certain details of construction and combinations of parts, will be hereinafter pointed out and described in the claims.

Figure 1 is a side elevation of a lasting machine embodying this invention. Fig. 2 is an end elevation on an enlarged scale of the forepart of the shoe support or jack, in-

cluding the toe band or wiper with its carriage and a preferred form of supporting and adjusting mechanism. Fig. 8 is a side elevation of the construction shown in Fig. 2. Fig. 4 is a detail view showing in side elevation a cap plate to be described and the parts immediately behind the cap plate. Fig. 5 is a view showing a modified construction of means for angularly adjusting the toe band or wiper transversely of the shoe support. Fig. 6 is an end elevation of the construction shown in Fig. 5. Figs. 6 and 6 are vertical sections illustrating details of the construction shown in Figs. 5 and 6. Fig. 7 is a side elevation on an enlarged scale of the toe lasting mechanism which I prefer to employ, said mechanism being shown also in Fig. 1. Fig. 8 is a front elevation of the mechanism shown in Fig. 7. 9 is a section on the line 99 of Fig. 8. Fig. 10 is a section on the line 10-10 of Fig. 9.

The frame of the machine comprises an upright hollow column having a backwardly extending arm 2 provided with a bearing 3 to receive the stem of the rotatable head A which carries the toe and heel lasting mechanisms. Said frame also has a forwardly extending arm 5 having a bearing 6 to receive the spindle of the shoe support or jack. The jack comprises a head 8 from which depends a spindle 10, said spindle being capable of both rotary and endwise movement in the bearing 6. Mounted for sliding movement on the head 8 of the jack is a carriage 12 for the usual last pin and a carriage 14 for the toe band or wiper 16. The jack spindle 10 is provided with two slots 18 and 19 arranged to be engaged by a spring-pressed locking pin 20 for securing the jack against accidental rotation when the shoe supported by the jack is presented with either its toe,or its heel end in position to be acted upon by the toe and heel lasting mechanisms. The upper ends of the slots 18 and 19 are beveled, as shown, so that when the jack is depressed the locking pin will be forced out of the slot engaged by it and will bear against the cylindrical portion of the spindle, which with the entire jack may then be turned to present the desired end of the shoe to the lasting mechanism. The said toe and heel lasting mechanisms are mounted upon

arms

22, 24 extending from the lasting head approximately at right angles to each other. Means is provided for locking the head against rotation when either the toe or the heel lasting mechanism is in position for acting upon the shoe, and for the purpose of automatically effecting the locking and unlock ing of the lasting head the locking pin 26, which is mounted in the arm 2 and arranged to engage recesses in the lower face of the head, is connected with the usual treadle employed for raising and lowering the jack. To this end a lever 28 is pivoted to the frame at 30 and its free end engages a recess 32 in the side of the locking pin. Said lever 28 is joined by a link 84 with a treadle 36 which is arranged to be depressed for lowering the jack. A spring 40 is arranged for normally pressing the locking device 26 upwardly into the recesses in the lower face of the head 4. Vith this arrangement the locking device will be Withdrawn automatically when the treadle 36 is depressed for lowering the jack, as it will have to be in order for the shoe to be turned whenever the lasting mechanism for the other end of the shoe is to be employed, and will be automatically raised into locking engagement with the head 4 when the jack is permitted to rise under the influence of the spring 42, which has connection with the treadle and a fixed portion of the frame, as shown in Fig. 1.

It is desirable that the lasting mechanisms be securely locked in their operative positions before the jack in rising reaches an elevation at which the shoe carried thereby might engage the lasting mechanisms. For the purpose of insuring this locking of the lasting mechanisms in advance of the complete rise of the jack the link 34 is passed loosely through the treadle lever 36 and a stop 44 is provided at some distance below the treadle when the latter is in its normal position. This arrangement permits the device 26 to be elevated by its spring 40 for making locking engagement with the last-- ing head during the first portion of the rise of the jack and before the shoe reaches the plane in which the lasting wipers are located.

The carriages l2 and 14 for supporting the heel pin and toe wiper respectively are arranged t be moved simultaneously oward or from the center of the jack, and to this end the carriages are connected by a right and left-handed screw-threaded rod 50 rotatably mounted in the head of the jack and held from endwise movementtherein. The rod 50 is provided with a Worm gear 52 engaged by a worm 54 having on its outer end a hand wheel 56.

The carriage 12 supports a casing 60 having a tubular portion adapted to receive a carrier 62 for the usual last pin 64. The casing is pivotally connected to the carriage 12 at a point 66 located at the rear side of the carrier 62. The casing is adjusted about the pivot 66 for canting the heel pin more or less forwardly by means of a screw 68 having a handle 70 and entering a threaded opening in a block 72 rotatably mounted in the lower end of the casing, as shown in dotted lines in Fig. 1. The carrier 62 for the last pin is exteriorly screw-threaded and is engaged by a nut 74 held against longitudinal movement in a notch in the casing. A stop screw 75 engages a longitudinal groove in the carrier and holds it against rotation while permitting it to be adjusted longitudinally by rotating the nut 74.

The toe band or wiper 16 is carried on two arms 80, Fig. 2, each of which is provided intermediate its ends with a ballshaped portion 82 received in a vertical cylindrical bearing 84 formed on the wiper carriage. The lower end of each arm has an eye or socket 86 in which a cylindrical nut 88 is rotatably mounted. The nuts are oppositely screw-threaded and are engaged by correspondingly threaded portions of an adjusting screw 90 which extends transversely of the jack and is provided with an operating hand wheel 92. By turning the adjusting screw 90 the arms, which it will be observed are levers fulcrumed in the guides or bearings 84, may be rocked in opposite directions transversely of the jack, and consequently the spread of the toe wiper supported on the upper ends of the arms may be varied to accommodate lasts of considerable difference in size. The screw may at any time be operated after the wiper or band has been raised into operative position for embracing the end portion of the shoe and in any special case the band may be thus caused to clamp the upper firmly against the sides of the last and hold it while the upper is folded over the last bottom by the crimping jaws and fastened. The screw 90 may be mounted on the wiper carriage in any convenientmanner so as to be capable of rotation, but not of endwise movement. Preferably, however, and as shown in the drawings, the screw is mounted in a block 94 which is secured to or formed integral with the front end of the stud 96, which is rotatably mounted and also longitudinally movable for purposes hereinafter described, in a bearing supported by or formed in the wiper carriage.

For the purpose of allowing the wiper or band to act properly upon lasts of slightly difierent sizes without'having to adjust its spread by means of the adjusting screw 90, said wiper is movably supported upon or connected to the arms 80. As herein shown, the upper end of each arm 80 is formed with an eye 97 which acts as a bearing for a stud One end of the stud is connected with the wiper by a ball and socket joint 100 formed in a plate 102 fixed to the wiper. The other end of the stud is provided with a head 104 to limit its movement toward the last and the two studs are pressed upon by two spring arms 106 which are loosely mounted between their ends upon studs 108 projecting from the wiper supporting arms 80. The upper ends of the spring arms 106 may be formed with openings to engage guide pins see Fig. 2 projecting from the stud 98, while the lower ends of the spring arms are provided with openings for engaging pins 112 projecting from the bearings 84 before described. These pins maintain the spring arms in proper position and the pressure to be exerted by the spring arms is adjusted by thumb nuts 114 on the studs 108. It will be readily understood that with this construction the toe wiper may be spread somewhat to receive a wider last than that for which the supporting arms are adjusted, notwithstanding the fact that the supporting arms themselves may be unyielding. It will, therefore, be necessary to manipulate the adjusting screw 90 for changing the spread of the wiper only for lasts varying considerably in width.

As heretofore stated, it is desirable to permit the band or wiper supporting arms 80 to yield in company transversely of the jack in the event that the toe to be embraced is unsymmetrical or that the pressure exerted by the crimping jaws of the lasting mechanism is greater upon one side of the shoe than upon the other side, and to this end the block 94 hereinbefore described as carrying the adjusting screw 90, is bored to receive a sleeve 102, see Figs. 2 and 6 said sleeve being capable of both endwise movement and rotary movement within the block 94,

. but being fixed by means of a screw 122 to the adjusting screw 90 which passes through it. The ends of the sleeve 120 are flush with the ends of the block 94 and the sleeve is normally prevented from moving endwise in the block by a stiff U-shaped spring 124, which embraces the block and engages both ends of the sleeve. This spring maintains the sleeve,

the adjusting screw, the supporting arms,

and the band or wiper in normal central position, but will yield to allow these parts and the toe of the shoe embraced by the band or wiper to move transversely of the jack to equalize pressure of the ends of the band against the sides of the toe or the stress exerted on the shoe by the crimping jaws during the lasting operation.

Improved means is provided for angularly adjusting the band or wiper transversely of the ack to adapt it for receiving lasts which are twisted,that is, in which the plane of the bottom of the forepart is inclined transversely to the plane of the bottom of the heel part. A block 130 having an upper, plane face to rest against the block 94 is provided with a segment-shaped lower face and is arranged to rock transversely of the jack in guideways in the wiper carriage. The curved lower face of the block is provided with worm teeth 132 for engaging a worm 134 on an adjusting rod 136 rotatably mounted in the carriage, but prevented from endwise movement therein, and provided with an operating handle 138. The center about which the block 130 is thus adjusted is coincident with the center,namely, the axis of the stud 96,about which the block 94 is movable, so that an adjustment of the block 130 by means of its adjusting rod 136 will incline the block 94 transversely of the jack and through the supporting arms 80 will tip the wiper transversely.

A modified construction of means for angularly adjusting the wiper transversely of the jack is shown in Figs. 5 and 6, in which the block 94 is provided with a depending portion 131 provided with a slot 133 which receives a pin 135 carried eccentrically on the end of a stud 137 which is rotatable in a bearing in the wiper carriage, the said stud having a handle 139 by means of which it may be rotated manually. It will be understood that any adjustment of the pin 135 by means of the stud and handle will turn the block 94 about the axis of the stud 96 and thereby incline the block transversely of the jack and correspondingly incline the wiper 16.

Provision is made for enabling the toe band or wiper to yield away from the heel pin of the jack in order to accommodate without adjustment shoes difi'ering slightly in length, and tothis end the stud 96 is provided with a cap plate 140, shown detached in Fig. 4, which is secured to the stud by a screw 142 and is pressed upon by springs 144 inserted in sockets formed in the outer end of the wiper carriage, as shown in Figs. 3 and 5. The springs hold the stud 96 normally in the position shown in Figs. 1 and 5 with the cap plate spaced from the adj a- 7 and the lower ends from the heel of the last in case the last is slightly longer than that for which the jack has been adjusted.

In the use of the machine, the last with a shoe thereon having been placed on the heel pin, the wiper 16 requires to be swung about its pivotal connection wit-h the supporting arms 80 from the position shown in Fig. 1 toward-the operative position shown in Fig. 3. For the purpose of thus actuating the wiper a crank shaft 150 is mounted in bearings in the upper portion of the carriage and is provided with a crank arm 152 which is connected to the wiper by an adjustable link 154, the shaft being provided with an operating handle 155. The operating handle supports a springpressed pawl 156 adapted to engage with ratchet teeth formed on a segment plate 158, as shown in Fig. Preferably and as herein shown, provision is made for imparting to the wiper a supplemental movement longitudinal of the jack while it is being swung forwardly by the means just described, and to this end an eccentric 160 is mounted on the crank shaft 150. The eccentric is embraced by an eccentric strap 162 which is connected by an arm 164 to one end of a lever 166. The lever 166 is fulcrumed intermediate its ends at 168 on the wiper carriage and its other or lower end is connected by a ball and socket joint to a slide 170 mounted in the carriage so as to be capable of horizontal movement longitudinally of the jack. The slide 170 as herein shown supports the stud -96, heretofore referred to, togetherwith its controlling springs 144. The eccentric is fixed on the shaft 150 in such a position with relation to the crank arm 152 that when the shaft is oscillated to cause the wiper to be swung on its pivots for exerting wiping action upon the upper, the lever 166 will be rocked to move the slide 170 and with it the block 94, the adjusting screw 90, of the wiper supporting arms 80 toward the heel of the last and thus move the wiper, which is pivoted to the upper ends of said supporting arms, away from the heel of the last. By this means the motion toward the heel of the last, which is given to the portions of the upper edge of the wiper as the latter is swung upwardly, is counteracted and all portions of the upper edge of the wiper are caused to move forwardly or toward the toe end of the last as they move upwardly toward the last bottom. Preferably the eccentric arm 164 is connected adjustably to the lever 166 to enable the operator to regulate the amount of movement given to the lever by the eccentric and thereby vary the amount of the supplemental forward movement imparted to the wiper by the mechanism above described. To this end the arm 164 is forked to embrace the lever 166 and is pivl otally connected to the ends of a pin 172 which extends through slots 174 in opposite sides of the lever 166, as shown most clearly in Fig. 3. The pin 172 is carried by a screw-threaded stud 17 6, which is adjustable longitudinally in a guideway in the lever and is engaged by a screw-threaded nut 178 carried in a notch in the lever 166 so as to be incapable of endwise movement. Rotation of the nut moves the stud 176 endwise in the lever, thereby varying the distance between the fulcrum 168 of the lever and its point of connection with the eccentric arm 164. By this means the extent of movement imparted by the eccentric 160 to the slide 170 and thence to the wiper may be varied according to the requirement of the work.

The toe and heel lasting mechanisms and their carriages are identical in construction and arrangement and only one, namely, the toe lasting mechanism shown in side elevation in Fig. 1 and in detail in Figs. 7, 8, 9, and lO,-will be particularly described. The carriage 180 of the toe lasting mechanism is adjustable on the arm 22 toward and from the jack by means of a screw 182 mounted for rotary movement only in the carriage and entering a screwthreaded aperture in the head 4. The screw 182 is provided with a beveled pinion 184 engaged by a similar pinion on the end of a shaft 186, which is provided with a hand wheel 188 by means of which the screw may be rotated for sliding the carriage forwardly or backwardly. The carriage is formed on its front face to re ceive the segmental slide 190, which is connected to the carriage by an arc-shaped tongue-and-groove connection, as indicated in Figs. 1 and 7, the center about which the arc is struck being a point at or near the operating portions of the crimping jaws hereinafter described, in order that when the slide 190 is moved upon the carriage to vary the inclination of the crimping jaws the vertical position of the operative portion of the jaws may not be altered materially. The slide 190 may be adjusted upon the carriage 180 by means substantially like those above described for adjusting the carriage on the arm 22. This means comprises a hand wheel 192 Fig. 8 fixed on one end of a sleeve 194, on the other end of which is a beveled gear 196. The sleeve surrounds one end of a short rod 198, the other end of which is carried in a boss on the carriage 180. Placed approximately centrally on the rod 198 is a collar 200, and carried in a hole bored through the collar and rod is one end of a pin 202 having a beveled gear 204 fixed on it so as to engage with the beveled gear 196, the pin being rotatable in the said hole, but prevented from endwise movement, all as clearly shown in Fig. 7. The

pin 202 extends beyond the beveled gear and comprises a screw-threaded portion which engages a threaded hole in a cylindrical block 206, which is rotatably carried in a holder 208 in the slide 190. By this arrangement the hand wheel 192 for operating the ad just-ing means for the segment slide is placed adjacent to the hand wheel 188 for the carriage adjusting means, whereby one wheel after the other may be conveniently engaged by the operator. The segmental slide 190 is formed at its upper end with a bearing 210 to receive a cylindrical slide 212 which carries the crimping jaws or lasting devices, said slide being movable endwise in the bearing and also adjustable angularly therein. The slide is operated by means of a lever 214 which extends through a recess running transversely across the slide and said lever is pivoted to the slide by a pin 216, all as shown most clearly in Figs. 9 and 10. The inner end of the lever is rounded and projects beyond the slide into a bearing formed by a circumferential slot 218 in the wall of the bearing 210. Conveniently and as shown in Fig. 9, this bearing for the inner end of the lever may be formed in a cap-or cover 220 secured to the outer side of the bearing 210 and projecting within the slot 218. The handle end of the lever 214 extends beyond the slide through a longitudinal slot 222 in the bearing 210', the slot being of greater width as well as greater length than the transverse dimensions of the lever, whereby the lever is allowed to have movement both horizontally and vertically for moving the cylindrical slide and the lasting plates or crimping jaws carried thereby forwardly with relation to the jack and also angularly. This provision for moving the jaws ang'ularly enables the operator to position the jaws accurately so that they shall act'uniformly upon the two sides of the last, even though the plane of the bottom of the last be inclined transversely. The lever 214 is connected to the crimping

jaws

224, 225 by

links

226, 227 respectively, the points of connection between the links and the lever being at a greater distance from the inner end or fulcrum of the lever than is the pivot pin 216 which connects the lever to the slide, as is clearly shown in Fig. 9. The crimping

jaws

224, 225 may be formed as shown in the drawings of two plates secured together by bolts 228, and said jaws are pivoted on a hollow stud 230, see Fig. 7, said stud being mounted in a lug 232 extending forwardly from the slide 190. The

portion of the stud on which the jaws are i treadle the locking devices pivoted is cone-shaped, as shown in Fig. 7 and a nut 234 is applied to the upper end of the hollow stud for securing it in position.

The toe and provided in accordance with this invention nism and width of the shoe.

with a central crimping plate 236, which is placed in the angle between the crimping jaws in position to act upon the extreme toe or heel end of the shoe for wiping the upper over the last at these points before the crimping jaws close to wipe the upper inwardly on the sides. It is frequently desirable in operating on shoes of different sizes or shapes to substitute one of these central crimping plates for another of a different form, and in accordance with this invention I have provided improved means for attaching the central crimping plate in position, said attaching means being adapted to enable said plate to be removed without disturbing the crimping

jaws

224, 225. As herein shown the central crimping plate 236 is clamped against the lower end of the hollow stud 230 by a headed bolt 238, which passes through an opening 240 in the plate 236 and thence extends upwardly through the hollow stud and is retained in position by a thumb nut 242. The opening 240 extends outwardly to the back edge of the plate 236, whereby when the nut 242 is turned to loosen the clamping bolt the plate may be withdrawn and another plate substituted therefor without removing the clamping bolt from the machine or disturbing in any manner the crimping

jaws

224, 225.

In the operation of the machine, the jack having been properly adjusted by the several mechanisms hereinabove described to adapt it for the particular work in hand, a last with a shoe thereon is applied to the heel pin and the handle 155 is raised for rocking the crank shaft 150 and swinging the wiper upwardly about its pivotal connection with its supporting arms 80. As the wiper rises it spreads or contracts, as may be required, to conform to the shape During the upward swinging movement of the wiper the eccentric 160 acts through the connections described for rocking the wiper supporting arms 80 in the direction for moving the wiper forwardly away from the heel of the last, whereby the wiper is caused to force the upper forwardly toward the toe of the last as said wiper rises. If the shoe being jacked is somewhat longer than that for which the toe and heel carriages have been adjusted, the springs 144 permit the wiper to yield forwardly in order that it may embrace such long last. The shoe having been properly jacked with the shoe support in the position shown in Fig. 1, the treadle 36 will be depressed. In this movement of the 20 and 26 for the jack and the lasting head, respectively, will heel lasting mechanisms are may be desired, toward the lasting mechaand the lasting head may also be turned to present the toe or the heel lasting plates in position to engage the shoe. The pressure on the treadle will then be reduced or discontinued and the spring 42 will raise the treadle and the jack for forcing the shoe upwardly into position against the lower sides of the lasting plates which will be suitably manipulated by the hand lever 214 to work the upper over the last bottom into posit-ion to be secured.
