48 Claims.

This invention relates to machines for fastening uppers to insoles. In the manufacture of some kinds of shoes it is the practice to mold the heel part of the upper, unattached to the forepart, before assembling it with an insole and mounting it on the usual last, the heel part being thus molded substantially in final shape and being provided in the molding operation with an inturned flange adapted to overlie the heel end of the insole when the molded heel part is assembled with the insole. An object of the present invention, among others, is to provide means for speedily fastening such molded heel parts to insoles in proper relation to the insoles. In accordance with the present disclosure this object is conveniently accomplished by certain modifications in the structure of a machine of a well-known type commonly used for lasting the heel ends of shoes, but it will be understood that the invention is not thus limited in its applicability and that the novel features are susceptible of various embodiments.

Commercial lasting machines of the abovementioned type are constructed largely as disclosed in United States Letters Patent No. 1,583,044, granted on May 4, 1926 on an application of C. H. Hoyt, although modified in some respects as further disclosed in other United States Letters Patent, including Letters Patent No. 1,558,737, granted on October 27, 1925 on an application of R. F. McFeely and Letters Patent No. 1,852,015, granted on April 5, 1932 on an application of J. C. Jorgensen. For purposes of this invention the wipers with which such a machine is provided for wiping the margin of the heel end of the upper inwardly over an insole are, as herein illustrated, maintained throughout the operation of the machine in fixed relation to each other while occupying positions commonly known as their advanced and closed positions. They accordingly serve simply as pressing members for pressing the inturned flange of the molded heel part of the upper on the insole in position to be fastened thereto. In the machine herein shown the fastening of the flange to the insole is effected by tack-driving mechanisms supported on these pressing members and constructed as disclosed in the above-mentioned Letters Patent No. 1,852,015. These mechanisms drive a row of tacks through the inturned flange and the insole while the flange is pressed on the insole. While the pressing members are thus maintained in fixed relation to each other during the operation of the machine, they are nevertheless adjustable, together with the tack-driving mechanisms assoelated therewith, for operating on shoe parts of diiferent sizes.

A machine of the above-mentioned type is provided with a work support which is movable in directions lengthwise and heightwise of a shoe thereon to carry the shoe into position to be operated upon, such work-presenting movements of the work support being commonly effected by the operator prior to the starting of the power operation of the machine, substantially as disclosed in the above-mentioned Letters Patent No. 1,553,737. With the pressing members positioned as above described, the work support thus serves to carry the inturned flange of the molded heel part of the upper to a position opposite the pressing members and into engagement with those members, the usual holddown for engaging the insole being omitted. As herein illustrated, the work support has mounted thereon a metal heelend form on which the insole and the heel part of the upper are positioned, although with obvious modifications of the work support an ordinary last may be used, if desired, in place of such a heel-end form. To assist in positioning the heel part of the upper in proper relation to the form and the insole before its inturned fiange is fastened to the insole, it is embraced and clamped against the end and side faces of the form by a heel band such as used heretofore in machines of the illustrated type. The workpresenting movement of the work support in a direction lengthwise of the form serves to carry the rear face of the molded heel part into engagement with the heel band, and the machine herein shown is so constructed that the heel part is thus engaged with the band before the work support receives its movement heightwise of the form toward the flange-pressing means. This aifords better insurance that the inturned flange of the heel part, if spaced from the insole, will be properly presented to the pressing means. As the form is then moved heightwise toward the pressing means, the heel band may have a frictional action on the rear face of the heel part tending to seat its inturned flange on the insole before it is pressed on the insole. After the starting of the power operation of the machine the form is moved more forcibly lengthwise toward the band and heightwise toward the pressing means, and the band also is closed about the form, to cause the heel part to be properly positioned and its flange to be pressed firmly on the insole before the fastening tacks are driven.

While a machine embodying features of the present invention may be used to complete the fastening of a molded heel part to an insole after the forward ends of its inturned flange have already been fastened to the insole in an earlier assembling operation, the machine herein shown is further provided with means whereby it is adapted especially to operate on heel parts which have not been previously assembled with insoles. For this purpose the movable work support has mounted thereon clamping mechanism for en gaging and holding the forward ends of the heel part during the movement of the support. As illustrated, this mechanism comprises pads which in response to the movement of a single operating member are moved inwardly to clamp the forward ends of the heel part against the sides of the form and are then moved heightwise of the form with a wiping action on the heel part tending to seat the forward ends of its flange on the insole if they are not already in contact with the insole, and further comprises members which then engage the forward ends of the flange and press them on the insole. The above-mentioned operating member in the machine herein shown is the usual treadle by which in a machine of the illustrated type the operator imparts the workpresenting movements to the work support, the invention providing means whereby the clamping mechanism is operated by this treadle before the work support is moved by the treadle. This clamping mechanism serves to hold the molded heel part and the insole on the form in proper assembled relation during the work-presenting movements of the work support and also assists thereafter in holding the heel part in proper position to be fastened to the insole.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In the drawings,

Fig. 8 is a perspective View of the molded heel part and the insole after the operation of the machine thereon.

The machine is provided with a work support 2 which comprises a post t mounted for upward and downward movements in a casting 6, this casting being mounted for rearward and forward swinging movements about a shaft 8 at its lower end, substantially as disclosed in Letters Patent No. 1,558,737. The post 4, instead of being provided as heretofore with means for supporting an ordinary last, is so constructed as to support at its upper end a metal heel-end form Ii! adapted to receive thereon an insole a and the previously molded heel part b of an upper, this heel part being provided with an inturned flange 0 arranged to overlie the heel end of the insole. For this purpose there is mounted in a slot in the upper end portion of the post a bar l2 having a rectangular upper end arranged to enter a corresponding recess in the form In and provided with a shelf l4 on which the form rests. The bar is supported on a bolt I6 for swinging movements about an axis extending widthwise of the form for the purpose of adjusting the bottom or insoleengaging face of the form in proper relation to the flange-pressing means hereinafter described. The bar is adjusted about the bolt it by means of a screw I8 threaded in the post 4, this screw being provided with an annular groove into which extend a pair of lugs 20 on the lower end of the bar, one of these lugs being visible in Fig. 1. The post 4 in the construction herein shown is supported initially at the proper height by a collar 22 which is fastened thereto and engages the upper end of the casting 6. At its lower end the post is hollow to receive a diametrically reduced portion 24 of a thimble 26 which has in its larger portion a plurality of pairs of diametrically opposite recesses 28 of different depths to receive selectively a pair of diametrically opposite fingers 30 on the post, substantially as disclosed in Letters Patent No, 1,583,044. Only one of the fingers and three of the recesses are visible in the present drawings. In the construction herein shown a screw 32 extends upwardly into the thimble 26 and is threaded in the diametrically reduced portion 24 of the thimble. As illustrated in Fig. 1, this screw is initially spaced from means, hereinafter described, whereby it is engaged underneath to impart upward movement at the proper time to the post 4, and the parts are so constructed that there is sumcient friction between the post and the thimble 26 to prevent the thimble from moving downward relatively to the post. As disclosed in the last-mentioned Letters Patent, such a thimble has been used heretofore to vary the height of the work-supporting post in operating on shoes of different sizes. Since the height of the present post A is determined adjustably by the collar 22, the thimble 26 and its screw 32 are used to provide, for any such adjustment of the post, the proper spacing between the head of the screw and the above-mentioned means below it for raising the post. It will be understood that the turning of the screw 32 provides for a finer adjustment than can be obtained by moving the thimble to different positions.

As illustrated in Fig. l, the work support 2 occupies initially a forwardly inclined position such as to permit the work to be readily mounted on the form l0. Pivotally connected to the casting 6 is a rearwardly extending rack bar 3% on the rear end of which is a block 36 arranged to engage the frame 38 of the machine to determine the initial position of the work support. This rack bar is movable, as in prior machines, in a guideway in a casting 40 mounted to rock about a shaft d2. From its initial position the work support is swung rearw-ardly by the operator, through the use of means hereinafter described, to present the work to the means which operates thereon. By such movement of the work support the rear face of the molded heel part b of the upper is carried into engagement with a heel band 44 constructed substantially as heretofore in machines of the illustrated type except that it is somewhat shorter lengthwise of the form. Thereafter the post 4 is raised, as also more particularly hereinafter described, to carry the form upwardly toward pressing means which presses the inturned flange c of the heel part down on the insole. This pressing means comprises a pair of pressing members 45, one of which is shown in Figs. 1 and 2 and the other in Fig. 3, these members being identical in construction with wipers used heretofore for wiping the margin of the heel end of an upper inwardly over an insole, as disclosed in Letters Patent No. 1,852,015. Like those wipers, the members 45 are guided for swinging movements about a common vertical axis, but in the machine herein shown such movements are only for purposes of adjustment in accordance with the size of the shoe being made,

the members being maintained throughout the I operation of the machine in fixed positions corresponding to the advanced and closed positions of the prior lasting wipers. The guiding means for the members 46, which is identical with the prior wiper-guiding means, is mounted on a member 48 which corresponds to the slide 23 shown in the last-mentioned Letters Patent, but unlike that slide is held permanently in a fixed position. For this purpose the member 48 is provided with a recess 58 into which extends a tongue 52 formed on a bracket 54 bolted to the frame of the ma-- chine. The members 46 are adjusted toward or from each other about their common axis by mechanism constructed substantially as disclosed in the last-mentioned Letters Patent. This mechanism comprises a slide 58 (Figs. 1 and 3) movably mounted in a recess in the member 48 and connected through levers 58 and pinions 68 to slides 62 which are movable in directions widthwise of the form and are connected to the front ends of the members 46. The slide 58 is connected by lugs 84 to a block 5%: in which is threaded a shaft 63 held against lengthwise movement relatively to the member 48 and connected by bevel gears 18 to a short shaft 12 rotatable in the frame. In the construction herein shown the shaft 12 is permanently connected by pinions 14 to a shaft "it on which is a hand wheel 78. It will thus be seen that by turning this hand wheel the pressing members 46 may be adjusted relatively to each other as required for operating on shoe parts of different sizes.

Mounted on the pressing members 418 and adjustable with them are tack-driving mechanisms 80, also constructed as disclosed in Letters Patent No. 1,852,015, which drive tacks through openings in the members and in the machine herein shown thus fasten the inturned flange of the molded heel part of the upper to the insole. Each of these tack-driving mechanisms comprises a block 82 fast on the corresponding member 48 and a group of tack drivers 84 one of which is visible in Fig. l, the group of drivers being moved downwardly at the proper time by a driver block 86 as fully disclosed in the last-mentioned Letters Patent. A row of tacks t (Fig. 8) is thus driven around the end and along the sides of the heel portion of the insole to fasten the molded heel part to the insole, the tacks being clinched on the form I 0,

The previously mentioned rearward swinging movement of the work support and the upward movement of its post 4 prior to the starting of the power operation of the machine are effected by the operator, in a manner generally similar to the movements of th work support in prior machines of the illustrated type, by depression of a treadle 88. The treadle is connected by a link to the rear end of a lever 92 pivotally mounted between its ends on the casting 6 below the shaft 8, and the front end of this lever underlies the lower end of a rack bar 94 movable upwardly and downwardly in the casting 6. Extending upwardly from this rack bar is a rod 95, and mounted for tipping movements on the upper end of this rod is a nipple 98 arranged to engage the head of the previously mentioned screw 32 to raise the post 4 in response to depression of the treadle 8B. As hereinbefore suggested, and for a purpose hereinafter described, the nipple 98 in the construction herein shown is spaced initially from the screw 32 as illustrated in Fig. I, the rod 96 being provided with a collar l 88 which engages a shoulder on the castin 6 to limit the downward movement of the rod. After the member 98 has been moved upwardly toward the screw 32, further depression of the treadle 88 serves first, for reasons hereinafter explained, to swing the work support rearwardly about the axis of the shaft 8 until the rear face of th molded heel part of the upper is carried into engagement with the heel band 44, such swinging movement of the work support by the treadle being due to the leverage afforded by the rear arm of the lever 92 and that portion of the casting 6 which is below the shaft 8. By reason of the resistance to further swinging movement of the work support upon engagement of the molded heel part with the heel band, still further depression of the treadle thereafter serves to swing the lever 92 about its connection with the casting 8 and thereby, through the rack bar 94 and the rod 96, to raise the post 4. In this manner the form It! is moved upwardly toward the pressing members 46 to cause them to press the inturned flange 0 down on the insole. If the heel part is not so positioned on the form that its flange c is actually carried into engagement with the members 48 by the rearward swinging movement of the work support, such upward movement of the form carries the flange into engagement with these members, the heel band 44 having a frictional action on the rear face of the heel part which tends to seat the flange on the insole before it is pressed thereon by the members 46. To render the heel band thus effective, it is so controlled that, as distinguished from prior machines of the illustrated type, it can have no upward movement. For this purpose the usual angular clip I02 which is fastened to the rear end of the band and connects it to its supporting slide 34 is seated against a washer I66 in engagement with the lower face of the slide. To prevent the heel band from rubbing too hard on the rear face of the molded heel part, the previously mentioned casting 40 is provided with a bumper I88 which is engaged by a lug Hi] on the rack bar 34 and is thereby moved rearwardly against the resistance of a spring H 2 just before the heel part engages the heel band. This mechanism is similar to that used heretofore for initiating forward movement of the work support in the return of the parts to their starting positions and has that function also in the machine herein shown.

The machine herein shown is further provided With means for clamping and holding the molded heel part and the insole in proper relation to each other and to the form during the movements of the work support, this means assisting also thereafter in holding the heel part in proper position to be fastened to the insole. For the purpose in view there is clamped on the post 4 by a screw H4 a bracket H8, and supported on this bracket for downward and upward movements is a yokeshaped holder I I8. Fast in this holder is a downwardly extending sleeve I20 which is movable in a bearing in the bracket, and the holder engages flat faces I22 (Fig. 4) on the bracket to prevent it from turning about the axis of the sleeve. A spring I24 mounted in a socket in the bracket I I6 and engaging a lug I28 on the holder II8 tends to raise the holder and maintains it initially in a position determined by engagement of a flange I28 (Figs. 1 and on the lower end of the sleeve I with the bracket. Mounted to swing about rods I30 on the holder I I8 are levers I32 having upwardly extending arms I34 which carry pads I36 arranged to engage the forward end portions of the molded heel part of the upper and to press them inwardly against the sides of the form. The pads may be made of rubber or other material suitable for engagement with the heel part without injury to its surface. The levers I32 have also downwardly extending arms I38 connected by a. pair of toggle links I40 to the head I42 of a rod I44 which is movable in the previously mentioned sleeve I20. At its lower end this rod is connected by a coupling I45 to the upper end of a rod I48 which extends downwardly into a sleeve I50 and is provided at its lower end with a nut I52. Between this nut and a thimble I54 which is threaded in the upper end of the sleeve I50 and through which the rod I48 may slide is a spring I58. The lower end of the sleeve I50 is connected by a coupling I50 to the frontv end of a lever I80 pivotally mounted between its ends on a bracket I02 fast on the casting 0. The rear end of the lever I is connected by a link I64 to the front end of th previously mentioned treadle-operated lever 02. It will thus be seen that in response to depression of the treadle 83 upward movement is imparted to the link I64 and downward movement to the sleeve I50, and that this sleeve acts through the spring I58 to impart downward movements to the rods I48 and I44, the rod I44 acting through the toggle links I40 to impart inward swinging movements to the lever arms I34 and thereby to cause the pads I30 to press the forward ends of the heel part against the sides of the form. By reason of the resistance of the form tofurther swinging movements of the arms I84, further depression of the treadle then causes the holder II8 to move downward against the resistance of the spring I24 and thus to carry the arms bodily downward, causing the pads I38 to have a downward wiping action on the forward ends of the heel part. This serves to seat the forward ends of the inturned flange of the heel part on the insole if they are not already in contact with the insole. By such bodily downward movements of the arms I34 inwardly extending fingers I 86 formed on the upper ends of the arms are also caused to engage the forward ends of the inturned flange and to press them down on the insole. It isto permit these operations to be performed by depression of the treadle 88 prior to the rearward swinging movement of the work support that provision is afforded, as hereinbefore described, for lost motion between the member 98 and the screw 32.

To insure that no swinging movement of the work support will occur until the forward ends of the heel part have thus been clamped, there is provided a spring I08 (Fig. l) which is connected to a pin I70 on the rear end of the rack bar 34 and to a plate I12 in engagement with the front of the frame 88 and tends to resist the swinging of the work support. It will be understood that the swinging of the support takes place in response to further depression of the treadle by reason of the resistance of the work to downward movements of the arms I34. After the swinging of the support the spring I58 in the sleeve I50 is yieldable to permit such further depression of the treadle as is required to raise the post 4. It will be noted that since the bracket H6 is fast on the post 4, the clamping mechanism supported on the bracket moves upwardly with the post, the spring I58 also yielding to permit this.

After the operator has swung the work support rearwardly and raised the post 4 by the treadle 88 as above described, he starts the power operation of the machine. Thereafter the heel band 44 is closed by power to press the molded heel part in close conformity to the sides of the form by the operation of mechanism disclosed in detail in Letters Patent No. 1,583,044. A portion of this mechanism is shown in Fig. .1 and comprises a pinion I14 which imparts rearward movement to a slide I'IB, this slide acting through a spring I'I8 to operate members (not herein shown) whereby the heel band is pressed inwardly toward the sides of the form. Also as in prior machines of the illustrated type, the

L movement of the slide I18 serves to operate mechanism for imparting further rearward movement to the work support and further upward movement to its post 4, thus causing the heel band to press more firmly on the rear face of the molded heel part and causing its inturned flange to be pressed more firmly down on the insole. This mechanism comprises a bell-crank lever I operated by the slide H8 and connected by a link I82 to a pawl carrier I84 on the shaft 42, the pawl carrier being provided with a pawl I80 which is arranged to engage a ratchet wheel I88 and thereby to turn a pinion I90 engaging the rack bar 34. The bell-crank lever I80 is also connected by a link I92 to apawl carrier I94 which is mounted on the shaft 8 and is provided with pawls I 96 arranged to engage a ratchet wheel I98 on the shaft and thereby to turn a pinion 200 in engagement with the previously mentioned rack bar 04. The link I92 is a two-part link the upper part of which is provided at its lower end with an abutment 202 which acts yieldingly through a spring 204 on a cylindrical casing 200 connected to the lower part of the link. In machines of the illustrated type as heretofore constructed the slide I76 receives two successive movements in the direction to operate the heel band and the work support in time relation to repeated overwiping movements of the lasting wipers, and the slide may be operated in this manner consistently with the objects of the present invention if it is desired to adapt an existing machine for the purpose in view with as few changes as possible, although but one such movement of the slide is necessary for the proper treatment of the work. Prior machines of the illustrated type have further been provided with additional means, including the lever I12 shown in Letters Patent No. 1,583,044, for imparting yieldingly to the work support movement in the direction to press the work against the heel band prior to the closing of the band, and preferably although not necessarily such means will be included in a machine constructed for the purposes herein disclosed.

To afford better insurance that the molded heel part will conform closely to the edge of the insole all around the heel end of the insole before the fastenings are driven, the work is preferably assembled by the operator on the form in the manner illustrated in Fig. 1 with the rear portion of the heel part tipped upward somewhat relatively to the from and the insole and with the insole pressed back against the heel part as thus positioned, after which the forward ends of the heel part are clamped against the form and the i insole in the manner hereinbefore described. Thereafter the upward movement of the form I toward the pressing members 46 tends to crowd portions of the rear end of the heel part which are immediately below its inturned flange in a rearward direction while maintaining them in contact with the edge of the insole until the flange is finally pressed on the insole. This has a tensioning efiect lengthwise of the form on the opposite side portions of the heel part adjacent to the flange; and if the force acting in this manner is great enough, depending upon how much the rear portion of the flange is initially spaced above the insole, the forward ends of the heel part may slip somewhat in a rearward direction relatively to the clamping members in contact therewith. In these respects the machine herein shown is adapted to carry out a novel method claimed in my copending application Serial No. 396.902 filed on June 6. 1941.

The manner of operation of the machine will now be briefly summarized. The operator first mounts a molded heel part and an insole on the form H3 in the manner illustrated in Fig. and then by depression of the treadle 88 operates the clamp arms I34 to clamp the forward ends of the heel part against the form and the insole. In this operation the pads I38 are first moved into clamping engagement with the sides the heel part (Fig. 6) and the arms I34 are then moved bodily downward a short distance to cause the pads to wipe the end portions of the heel part in a downward direction and then to cause the fingers lSB to clamp the ends of the inturned flange down on the insole (Fig. 7). Further depression of the treadle 88 then serves to swing the work support rearwardly to carry the rear face of the molded heel part into engagement with the heel band 44 and thereaiter to raise the post 4 to move the form upwardly toward the pressing members 15. In this upward movement, if the parts of the work are initially presented as shown in Fig. 1, the form serves to force the extreme rear end of the insole toward the inturned flange 0 while maintaining close contact of the edge of the insole with the rear portion of the heel part, as hereinbefore explained, and then to press the insole against the flange and the flange against the members 36 rearwardly of the clamping fingers 163 which are still in clamping engagement with the forward ends of the flange. In this operation also, under some conditions, the heel band ll may have a downward wiping action on the rear face of the heel part, as hereinbeiore explained. The operator next starts the power operation of the machine, and in the course of its operation the heel band 44 is closed to pl'GSS the opposite side portions of the heel part rearwardly of the pads I35 against the form, the

F or work support is operated to move the form with greater force in rearward and upward directions, and then the tack-driving mechanisms are operated to fasten the flange of the heel part to the insole, the points of the tacks being clinched on the form. The operator continues to hold the treadle 88 depressed and thereby to maintain the clamping pressure on the forward ends of the molded heel part at least until near the end of the cycle of operations of the machine. In the return of the parts to starting positions the work support is swung forwardly to present the work in position to be removed from the form, the work then having the appearance illustrated in Fig. 8.

As hereinbefore suggested, the machine may be used, if desired, to operate in the manner described on work positioned on an ordinary last instead of on a metal form such as herein shown, the work support being modified in such manner as to support a last as in prior lasting machines of the same general type. Accordingly, the term form as used in the appended claims is intended, unless otherwise required by the context, to include a last as Well as a form of the character herein illustrated. It will also be recognized that the machine may be used to fasten the previously molded heel portion of a full-length upper to an insole, and unless required by the context, therefore, the term heel part as used in the claims is not intended to be limited to a heel part which is unattached to the forepart.

Having described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:
