application of Matthias Brock. While the invention is herein illustrated in its application to the manufacture of pre-welted shoes, it is to be understood that the invention is not limited in its scope to machines for use in the manufacture of such shoes but is applicable, in certain of its asing their wiping movements.

pects, to machines for use in the manufacture of other types of shoes.

Objects of the present invention are to facilitate and improve the manufacture of shoes and more particularly to improve bed lasting machines for operating on pre-Welted shoes such, for example, as the machines illustrated in United States Letters Patent No. 2,042,518, granted June 2, 1936 upon my application and application Serial No. 43,567, filed October 4, 1935 in the name of Rene E. Duplessis.

In the machine illustrated in my copending application above referred to there are provided, in combination with the usual toe-lasting wipers and heel-lasting wipers, side-lasting wipers having wiping movement widthwise only of a shoe in the machine. It is now proposed to provide side wipers having wiping movement lengthwise as well as widthwise of the shoe and accordingly a r feature of the invention consists in the combina- 0 tion with end-embracing lasting wipers constructed and arranged for wiping movement lengthwise of a shoe in the machine and widthwise of the shoe, of side-lasting wipers constructed and arranged for wiping movement by the end-lasting wipers both lengthwise and widthwise of the shoe, and means for supporting those ends of the side wipers remote from the end wipers and for guid- In the illustrated 5 machine the side-lasting wipers are supported by the heel wipers and guided by connections to the toe-lasting wipers. The illustrated construction provides a combined forward and widthwise movement of the side-lasting wipers which is par- 0 ticularly effective for lasting the shank portion of the shoe.

For supporting an inverted upper in the machine there is provided, in accordance with a further feature of the invention, a member extending heightwise of the upper for engagement with the upper in the region of the apex of the angle defined by the interengaging surfaces of the welt and upper and hereinafter referred to as the welt crease. For engaging the upper-attaching face of the welt to position the Welt for attachment to an outsole there is provided welt engaging means which in the illustrated machine is the toe lasting Wipers. For effecting relative movement of the upper-supporting member and the toe-lasting wipers thereby to bend the welt of the supported upper into sole-attaching position there is provided means which in the illustrated machine is operated by the downward movement of a depressor which forces the forepart of a last into the supported upper.

In order to insure uniform wiping of the welted margin of the upper over the last bottom there are provided, in accordance with a further feature of the invention, shoe-engaging members constructed and arranged to be operated by closing movements of end-lasting wipers to centralize the last relatively thereto, said members, in the illustrated machine, being operated by the advancement of the heel wipers. The shoe-engaging members perform their function without limiting the overwiping movement of the heel wipers. As herein illustrated, the shoe-engaging members comprise resilient plates having the general shape of the heel portion of a shoe and secured to the heel wipers adjacent to their interengaging edge faces, the forward portions of said plates being left free to flex as the heel wipers last the heel portion of a shoe in the machine.

These and other features of the invention will now be described with reference to the accompanying drawings and will be pointed out in the appended claims.

In common with prior machines of the illustrative type, the machine illustrated in the drawings is provided with toe-lasting wipers 23 (Fig. 4) and heel-lasting wipers Z2 and in common with the machine illustrated in my copen-ding application and in the application filed by Rene E. Duplessis both above referred to the machine herein illustrated is provided with side-lasting Wipers 24 and with a series of last-guiding members or fingers 26 (Fig. 1) for guiding the forepart of a last as it is depressed into the forepart of an upper in the machine by a depressor member 28 which is constructed and operated the same as the last depressor of the Duplessis machine. As illustrated in Fig. 6, the last-guiding fingers 28 are made straight throughout their entire length in order to permit downward movement of the last and upper relatively to the fingers after the last has been positioned in the upper. As illustrated in Figs. 1 and 3, the last-guiding fingers are mounted on a yoke 39 which is mounted for vertical swinging movement on a slide 32 mounted in the toe head 3:1 for movement toward and from the toe end of a shoe in the The finger assembly is moved away from the toe end of the shoe by a spring 36 one end of which is connected to a pin 38 in a hollow boss 48 extending upwardly from the slide 32 and the other end of which is connected to a hook 42 secured to a bracket 45 on the toe head. The spring 35 holds the slide 32 against a stop pin 48 mounted in a bracket 48 on the toe head. For swinging the finger assembly from its elevated position in Fig. l to its operative position in Fig. 6 a handle 50 is secured to the arm 52 which carries the yoke 39. For positioning the fingers heightwise thereof relatively to the upper in their operative position, as seen in Fig. 6, a stop screw 5-. is mounted in the central portion of the yoke 30 and arranged to engage the top plate 55 of the toe head. The finger assembly is supported in.

its retracted position, as illustrated in Fig. l, by a spring-pressed pin 53 mounted at the upper end of a short arm extending upwardly from When the finger assembly is in its retracted position the pin 58 engages the depressor member 28 and thereby holds the finger assembly against downward movement. The pin 53 is manually retracted to permit downward movement of the finger assembly and in order to facilitate manual retraction of the pin it is provided with a knob 62. As the finger assembly moves downwardly the pin 58 slides against the front face of the depressor member 28 and during the latter part of the advancement of the depressor 28 the depressor moves away from the pin 58 and the pin springs back into its initial position. During the retraction of the depressor the pin 58 is engaged thereby and the finger assembly is returned to its retracted position. The mechanism for operating the depressor 28, which is substantially the same as in the machine of the Duplessis application above referred to, comprises a treadle 83 (Fig. 2), and a vertical slide (Fig. l) mounted in the toe head 34 and provided with connections, including an extensible link '13, to the treadle 63. At its upper end the slide 65 is provided with a crosshead 61 having in its front face a horizontal groove within which travels a roll 89 (Fig. 3) carried by a bracket H on the hub of the last depressor 28.

Referring now to Fig. 3, the heel portion of a prewelted upper such, for example, as the upper 64 illustrated therein, is supported by its welt upon the heel wipers 22 and clamped against the wipers by a clamping plate 68, which is secured to the free end of a vertically swinging arm 68 carried by the heel head 70. The heel clamp and its operating mechanism is the same as in the machine of the Duplessis application above referred to. The operating mechanism for said clamp includes a treadle 12 (Fig. 2) which is depressed after the plate 66 has been manually advanced into position to engage the welt of the upper 8 2, the depression of said treadle operating to impart clamping pressure to the plate 66 through connections including a treadle-actuated rod 14 (Fig. l), a vertical slide 16 carried by the heel head, a bell crank lever 78 arranged to be actuated by said slide, and operating connections (not shown) from the bell crank lever to the arm 68.

For supporting the forepart of the upper 64 the illustrated machine is provided with a toe post 80 (Fig. 6) having at its upper end a head 82 which has in plan view the general outline of the forepart of the upper. Secured to the curved wall of the head 82 is an upwardly extending plate 84 the upper edge of which engages the upper 64 in the welt crease. The toe post 80 is yieldingly supported on a horizontal arm 86 provided in the machine frame. The illustrated mechanism for supporting the toe post comprises a sliding pin 88 mounted in a hollow screw 89 extending downwardly from the toe post. The pin 88 extends upwardly from the screw 89 into a central bore in the toe post and engages at its upper end a spring 98 in said bore. The toe post 83 is slidably mounted in a vertical hole in an upwardly extending head 92 of a horizontal sliding rod 9% carried by a hollow dovetail slide 96 (Fig. 9) mounted in a dovetail groove in the bottom of the toe head 34. The sliding rod 94 is held against turning movement in said dovetail slide by a pin 98 extending upwardly into a slot I00 (Fig. 5) extending lengthwise of the slide 95. For holding the toe post 89 against turning movement and thus positioning the plate 84 for the reception of the forepart of an upper the head 92 of the sliding rod 94 is provided with a pin I02 the inner end of which extends into a vertical groove 05 in the toe post. As illustrated in Figs. 5 and 8, the dovetail slide 86 is provided with parallel vertical cars it which engage slabbed-oif portions 68 at opposite sides of the head 92 of the sliding rod 94. Projecting outwardly from one of the ears M6 is a boss H0 which carries a screw H2 which has secured between clamping nuts l M at one end thereof a stop plate H6 which, as illustrated in Fig. 8, is arranged to engage the head 92 of the slide 94. The head 92 is urged against the stop plate by a compression spring II8 (Fig. one end of which engages the toe head and the other end of which is seated in a socket in the head 92. The end of the screw II2 opposite the stop plate H6 provides a stop for locating the dovetail slide 96 by engagement with the toe head, the dovetail slide being held in its position illustrated in Fig. 5 with the screw H2 in engagement with the toe head by a tension spring II9 (Fig. 1) which is substantially stronger than the spring I I8. The stop plate II 6 is adjusted endwise of the screw II2 to determine the initial position of the upper-supporting plate 84 lengthwise of a shoe in the machine, or if desired, the screw I I 2 together with the stop plate II6 may be adjusted by turning the screw in the boss I III. The preferred adjustment, as illustrated in Figs. 10 and 12, is such that the wipers engage the plate 84 at an intermediate stage in their advancement, and in their retracted positions are spaced from said plate sufficiently to permit upward movement thereof. The horizontal movement of the last-guiding fingers 26 by the spring 36 after said fingers have been positioned within the upper 64 moves the forepart-supporting assembly forwardly of the upper 64 from its position in Fig. 5 to its position in Fig. 6, the extent of said movement being indicated in Fig. 6 by the separation of the head 92 from the stop plate H6. During the forward movement of the forepart supporting assembly the heel end of the upper is held from forward movement by the clamp 66 and consequently the upper is drawn or tensioned lengthwise thereof and held under tension by the fingers 2B for the reception of a last. It will be understood that the desired operation of the finger assembly 26 and the forepart-supporting assembly requires an accurate adjustment of the toe head relatively to the heel head for the size of shoe to be operated upon.

In its position in Fig. 6 the upper 64 is supported with its welt-ed margin substantially above the plane of the toe wipers 20. The upper is positioned for the operation of the toe-lasting wipers 20 thereon by downward movement of the forepart of the upper and the forepart-supporting assembly by the latter part of the downward movement of the depressor 28, which movement forces the forepart of the last, together with the forepart of the upper and the forepart supporting assembly, downwardly into their positions illustrated in Fig. 7. The illustrated mechanism for efi'ecting downward movement of the forepart-supporting assembly comprises a swinging arm I20 (Fig. 3) pivoted to'a bracket I2I on the toe head and provided with an inwardly extending arm I22 which carries a screw I24 (Fig. 6) the lower end of which engages a plate I26 secured to and projecting outwardly from a base plate I21 provided in the head 82 of the toe post. The arm I29 is moved downwardly by the last depressor which, as illustrated in Fig. 3, is provided with a bracket I3!) having a stop screw I23 which, as illustrated in Fig. '7, engages the upper edge face of the arm IZfl during the latter part of the downward movement of the depressor, which movement is limited by the engagement of a stop screw I29 (Fig. 1) with the yoke 39. As

face of the last and the upper edge of the uppersupporting plate 84 into a position which permits overwiping movement of the toe wipers 20.

Referring now to Fig. 10, the illustrated machine is provided with side-lasting wipers 24 which operate on the shank and ball portions of a pre-welted upper by engagement with the upper in the region of the welt crease. In order to facilitate the introduction of the Wipers 24 into the welt crease of an upper in the machine said wipers are made of very thin material. The side wipers are supported upon the toe wipers 20 and the heel wipers 22 with their wiping edges substantially in alinement with the wiping edges of the toe wipers and the heel wipers. The side wipers are moved lengthwise and widthwise of an upper in the machine by the heel wipers 22 through pivotal connections comprising headed screws I46 mounted alternatively in a series of tapped holes I42 in the heel wipers 22. Said holes are arranged in lines extending lengthwise of an upper in the machine and afford adjustment of the side wipers for different sizes of uppers. The movements of the side wipers 24 by the heel wipers are guided and directed by headed screws I44 projecting upwardly from the outer end portions of the toe wipers 20, respectively, and extending through slots I46 provided in the side wipers. In lasting pre-welted uppers in the illustrated machine the rear part is lasted first in order to get a wiping action at the ball portion of the upper having a forward component of movement as indicated by the arrows on the side wiper plates in Figs. 9 and 11. It will be seen that the direction of movement of the side wipers 24 is determined somewhat by the direction of the slots I46 provided therein, said slots, as illustrated in Fig. 9, being substantially parallel to the wiping edges of the side wipers. This arrangement of the slots not only affords the desired wiping action of the side wipers but also provides a wiper assembly wherein the wiping edges of the toe wipers and side wipers are in alinement with each other at all times.

For supporting the heel portion of a last the illustrated machine is provided with a yielding;

heel support or post I48 (Fig. 1) provided with a flat head IE!) on which the last is movable lengthwise and widthwise thereof to position it relatively to the lasting wipers. For centering the heel portion of the last relatively to the heel wipers 22 said wipers are provided with a pair of resilient last-positioning members I52 (Fig. 10). Referring to Fig. 11 illustrating the last-engaging member extending downwardly from one of the heel wipers illustrated in Fig. 10, the illustrated last-engaging member comprises a re silient metal plate I54 secured to a block I56 extending downwardly from the wiper plate adjacent to that edge face of the wiper plate which in the open position of the wipers, as illustrated in Fig. 10, coincides with the longitudinal median line of a shoe in the machine. The plate I54 is secured to the outer face of the block I55 and arranged perpendicularly to the under surface of the heel wiper. The plate I54 extends laterally and toward the toe wipers from the block I56 and has the general curvature of the wiping edge I58 of the heel wiper 22 but converges somewhat relatively to said wiping edge and thus provides a construction wherein the end portion of the plate adjacent to the block I55 is spaced from the wiping edge I58 a distance somewhat greater than the overwiping movement required for lasting pre-welted shoes while the opposite end portion of the last-engaging member is arranged with its last-engaging surface substantially in vertical alinement with the wiping edge I58. The side face of the block I56 nearest to the wiping edge I58 of the heel wiper is arranged in alinement with the curved portion of the plate I54 and together with said curved portion of the plate is faced with a nonabrasive member or pad I60 which, as illustrated in Fig. 11, comprises two layers of grain leather which are riveted together and secured to the plate I54 by means of a staple I62 the crossbar of which lies between the two thicknesses of leather and the legs of which extend through the outer thickness only and through suitable holes in the plate I54, the projecting ends of said staple being turned outwardly against the outer surface of said plate. Referring now to Fig. 10, it will be seen that the illustrated last-positioning members I52 provide means for engaging the heel portion of an upper on its last during the closing movements of the heel wipers and thereby center the heel portion of the last relatively to the wipers before the wipers move inwardly over the last bottom to perform the overwiping movement. The resilient plates I54 are strong enough to move the heel portion of the last into a central position relatively to the heel wipers if the last is out of position but are sufficiently yielding to permit overwiping movement of the heel wipers with no appreciable increase in effort on the part of the operator.

It will be seen that the forepart of the last is centered relatively to the toe wipers 20 by the upper-supporting plate 84 which, as illustrated in Fig. 10, is centrally located relatively to the wipers, and as illustrated in Fig. '7, positions the last relatively to the toe wipers for the overwiping operation.

In lasting pre-welted uppers in the illustrated machine the heel portion of an inverted upper is positioned on the heel wipers 22 and the back seam of the upper is brought into alinement with the adjacent ends of the wiping edges of the heel wipers. The heel clamp 66 is then brought into engagement with the sole-attaching face of the welt in order to secure the upper in position on the last. The toe head 34 is then adjusted, if necessary, to bring the forepart-supporting plate 84 into alinement with the welted margin of the forepart of the upper. The upper is then positioned on the plate 84 and the toe wipers 20 are brought into engagement with said plate, as illustrated in Fig. 6. The last-guiding fingers 26 are then swung downwardly from their position in Fig. 1 and during their downward movement a dog I66 carried by the finger assembly engages a stop or shoulder provided in a plate I68 on the top plate of the toe head. The dog engages the plate while the fingers 26 are above the supported upper and causes the finger assembly to move rearwardly of the upper during continued downward movement thereof in order to position the fingers for entrance into the upper. The dog I66 is pivoted to the arm 52 which carries the yoke on which the fingers 26 are mounted and is yieldingly held by a spring I!!! against a pin I12 on said arm. During the latter part of the downward movement of the finger assembly after the fingers have entered the supported upper a short pin I14 in the free end of the dog I66 engages the top of the plate I68 and provides afulcrum point about which the dog is swung to disengage it from the shoulder provided in the plate I68. After the dog has been disengaged from the shoulder the spring 36 moves the slide 32 and the finger assembly carried thereby forwardly of the upper into engagement with the interior of the welted margin of the upper at its toe end. Further movement of the slide 32 by the spring 36 moves the finger assembly, together with the uppersupporting assembly, forwardly of the upper, said slide finally coming to rest against the stop screw 46. During such forward movement of the toe-supporting assembly the operator maintains engagement of the toe wipers 20 with the upper-supporting plate 84 in order to prevent the welt I32 from becoming positioned between the wiping edges of the toe wipers and the uppersupporting plate 84. After the finger assembly 26 has been swung downwardly into the supported upper and moved forwardly of the upper by the springs 86 as above described the heel portion of a last is positioned in the heel portion of the supported upper and the forepart of the last is positioned within the finger assembly 26. The last depressor 28 is then operated to force the last into the supported upper and to move the upper and the forepart-supporting assembly downwardly from their positions in Fig. 6 to their positions illustrated in Fig. '7 The heel wipers 22 and the side wipers 24 are then ad vanced to last the rear portion of the upper and then the toe wipers are advanced to last the toe portion of the upper. It will be seen that the inward movement of the side portions of the toe wipers imparts a corresponding movement to the side wipers 24 thereby completing the lasting of the ball portion of the upper. The last-guiding fingers 26 and the last depressor 28 are then returned to their respective initial positions, the toe wipers 20 operating thereafter to hold the last and the forepart-supporting assembly at the limit of their downward movements, as illustrated in Fig. 14. The upper is then secured in lasted position by the cement attachment of an outsole to the welt I32.

While the invention has been illustrated in its application to machines particularly adapted to the lasting of pre-welted shoes, it is to be understood that the invention is not thus limited in its scope, certain features of the invention relating to lasting machines generally.
