G. GODDU WORK SUPPORT Oct. 29, 1929,

Filed Sept. 4, 1-925 WVQWUH- l atented Oct. 29, 1929 UNITED STATES PATENT oFFicE GEORGE GODDU, OF \VINOHESTEB, MASSACHUSETTS, ASSIGNOR T UNITED SHOE CHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY WORK SUPPORT Application filed September This invention relates to fastening-inserting machines and is illustrated herein as embodied in a fastening-inserting machine having a work support adapted to present shoes having high heels to the fastening-inserting instrumentalities of the machine for the insertion of a row of slugs parallel to the edges of the toplifts of the heels.

High heels are ordinarily made with a substantial wedge so that the attaching surface and the tread surface of the heel are arranged at a considerable inclination to each other. Since the thimble of a last is positioned with its axis substantially at right 3 angles to the heel-seat surface of the last, it

follows that if a shoe upon a last is supporter. upon a vertical last pin, constituting part of the work support of a fastening-inserting machine, the toplift of the heel will be inclined to the presser plate of the machine at an angle equal to the inclination between the tread surface and the attaching surface of the heel. This angle will vary according to the height of the heel and may be as much as twenty or thirty degrees. The operation of a fastening-inserting machine under these conditions is impracticable since it would put a dangerously great pressure upon the edge of the heel and also would result in the fastenings being inclined excessively.

On the other hand, a factor which adds to the difiiculties met in attempting to provide a satisfactory work support applicable to the slugging of high heels is the fact that it is often desired to present the work with the tread face of the heel inclined somewhat, for example three or four degrees, to the presser plate of the machine. This localizes the pressure at the edge of the heel adjacent to the position at which the slug is inserted, and

tends to prevent bulging of the leather of the top lift adjacent to and between the slugs. It is also causes the fastenings to toe in away from the contour surface of the heel in a manner which is advantageous, for example, in

the case of Louis heels.

In view of the foregoing, it is an object of the present invention to provide an improved work support which will present a shoe having a high heel to the fastening-inserting-in- 4, 1925. Serial No. 54,476.

strumentalities of a fastening-inserting machine with the tread surface of the heel either parallel to the presser plate of the machine or, if desired, at a slight angle to the presser plate so as to localize the pressure at the edge of the heel and to direct the fastenings somewhat away from the contour surface of the heel, and which will maintain the parallel or slightly inclined relation of the tread sur face of the heel to the presser plate of the machine unchanged during the insertion of a row of fastenings parallel to the edge of the heel. It is a further object of the invention to provide a work support of this character which will be universal in its applicability to the presentation to a fastening-inserting machine of shoes having the wide variety of heels which are used in the manufacture of shoes.

To facilitate the maintaining of the uniform relation of the tread surface of the heel and the presser plate of the machine during the insertion of a row of fastenings parallel to the edge of the toplift, the work-carrying member of the illustrated machine, is mounted for universal horizontal movement and is arranged so as to be solidly supported substantially in alinement with the line of drive of the fastenings so that a tendency, which otherwise would exist to tilt the'work and the work support as each fastening is inserted, is eliminated. Stated more specifically, the work support of the illustrated machine comprises a rod having a last pin rigidly connected to its upper end but adjustable throughout a considerable angle. This rod, which may itself be adjusted either to a vertical or to a somewhat inclined position, is supported by a table carried by the horn shaft of the machine and bears upon the table substantially in alinement with the line of drive of the fastenings. Suitable means is provided for permitting bodily horizontal movement of the rod and last pin in any direction over the surface of said table as well as to permit rotary movement of the rod about its axis, while restraining the rod from tilting. In the insertion of a row of fastenings parallel to the'edge of the toplift of a heel, the work, as well as the last pin and rod,

moves first bodily in a direction parallel with the lateral edge of the heel. then, as the fastenings are inserted about the rear of the heel, the work, the last pin and rod rotate, and finally as the fastenings are inserted along the other side of the heel, the work, the last pin and the rod are again moved bodily pan allel to the edge of the heel. High heels have comparatively small toplifts and accordingly the bodily movement oi? the last pin and rod is small and is not such as to move the hearing of the rod upon the supporting plate sub-- stantially out of alinement with the line drive of the fastenings.

With the above and other objects and leatures in view, the invention will now be described in connection with the accompanying drawings and pointed out in the claims.

In the drawings,

Fig. 1 is a side elevation and Fig. 2 is a front elevation of the tastening-inserting instrumentalities and of the work support of a fastening-inserting machine embodying the present invention with a shoe supported for r the insertion of slugs in the toplitt oi its heel.

The illustrated machine is provided with a presser plate 8, against which is pressed the tread surface of the heel of a shoe to he slugged, and with an edge gage 9 arranged to guide the work as the fastenings are inserted. The machine is also provided with an awl 10 arranged to penetrate and feed the work and with a throat member or driver guide 12 and a driver 14: reciprocated theretlnough to irsort fastenings. These parts may be 01 a; desired construction and may be operated 131. any desired manner, for example as shown in Letters Patent of the United States No. 786,190, granted March 28, 1905, on an application of Louis A. Casgrain.

The frame of the illustrated machine is provided with a post or column 16, within which is mounted a vertical. sliding shaft 18 controlled by suitable mechanism oi well.- known character, for example such as that oi: said Letters Patent No. 786,190, to release the pressure upon the work during the feed ing movement of the awl and to clamp the work against the presser plate 01": the ma chine during the driving of the fastenin such mechanism providing substantially umform clamping pressure irrespective of variations in the thickness of different parts of the work. At its upper end shaft 18 carr s a plate 20 securely clamped thereto and provided with an approximately horizontal. upper surface 22 which may be slightly dished, if desired, and is provided with an ele ated rim 24:.

Securely clamped to shaft 18 is a block 6 to which a yoke 80 pivoted about a horizontal axis at 28. Pivoted to yoke 80 at 352 for movement about a horizontal axis at right angles to the pivotal axis of yoke an upwardly extending arm 34 having cured to its upper end a sleeve 36. To limit the pivotal movement of yoke 30 the latter is formed with a rearwardly projecting finger 88 in the path of movement of which is an adjustable stop carried by block 26. To limit the pivotal movement of arm 34, this arm is provided with a pin 42 passing between a pair of lugs 44, at carried by yoke 30. Sleeve 36 carried by the upper end of arm 34: is adjustable about a pivot bolt 46. To facilitate this adjustment, sleeve 36 is formed with a forwardly projecting linger 48 bearing upon an adjustable stop, illustrated as a screw 50, carried by arm 84. Screw 50 may be adjusted to bring sleeve 36 into the des"' d position with the vertical axis of its here either vertical or slightly inclined and sleeve 36 may then be locked in that position by tightening up pivot bolt d6.

li lountcd for rotary and vertical sliding movement in the bore of sleeve 86 is a rod 52 l aving its lower end somewhat rounded and supported by and bearing upon plate 20. By reason of the pivotal mounting of arm 3% and yoke 30, rod 52 may be moved b'odily in any direction horizontally over the surface of plate 20, such movement, however, being limited by the elevated rim 2% of plate 20. Atall times, however, tilting movement of red 52 is prevented by sleeve 36.

At its upper end rod 52 is formed with a yoke Set to which is adjustably but rigidly secured by pivot bolt 56 a bracket 58 formed wit a slideway 60 carrying the base block 62 oi? a last pin 6i. Last pin Gt may be clamped in adjusted. position relatively to bracket 58 by a bolt (36. In, order more firmly to secure bra 58 in adjusted position, the latter is formed with a serrated surface 68 engaged by a correspondingly serrated surface of a block 70 carried by yoke 54:.

In order to limit the relative vertical movement oi rod 52 and sleeve 36, red 52 is formed with a slot 71 arranged to receive a pin 72 which is also received by a horizontal slot T l formed in sleeve 36 and extending through somewhat more than half its circumference so as to permitthe desired rotary movement of rod 52 relatively to sleeve 86. To return the work support to worlerecciving position after the pressure has been released upon the conclusion of the insertion of a row of fastenings, a torsion spring 76 is anchored at one end as shown at 78 to sleeve 36 and is secured. at the other end to pin 72. As the work is rotated timing the insertion of the fastcnings spring I 6 is tightened and upon the release out the pressure, the torsion of the spring acts to turn rod 52 and last pin 64 into position for the commencement of the insertion of another row of tastenings. Spring 76 serves to prevent the escape of pin 72, being received in a circumferential groove formed about or beneath the head of the latter.

In the operation of the device, bracket 58 is adjusted angularly so as to bring the toplift of the heel to be operated upon into the desired relation with the presser plate 8 of the machine. In operating upon a high heel the adjustment is preferably such as to cause the edge of the heel to bear upon the presser plate in the-manner shown in Fig. 1 with the tread surface of the heel at a slight inclination to the presser plate. Last pin 64 is then adjusted forwardly or rearwardly, if necessary, so that when the heel is properly positioned relatively to the edge gage of the machine the lower end of rod 52 will bear upon and be supported by plate 20 at a point substantially in alinement with the line of drive of the fastenings. With the parts thus positioned a row of fastenings may be inserted parallel to the edge of the toplift without disturbing the angular relation of the toplift to the presser plate of the machine. During the operation along the sides of the heel the last pin 64 and rod 52 will move bodily transversely of the machine through a short distance but not sufliciently to bring the bearing of rod 52 upon plate 20 substantially out of alinement with the line of drive. During the insertion of fastenings at the rear of the heel, last pin 64 and rod 52 will rotate about the axis of rod 52, which, of course, corresponds with the axis of sleeve 36 which serves as a bearing for the rod 52. As the thickness of the work increases in passing from the breast to the rear of the heel, and as it decreases in passing in the opposite direction, rod 52 will move axially of sleeve 36, plate 20 being correspondingly adjusted downwardly or upwardly by the pressure controlling mechanism of the machine. At all times, however, rod 52 will be restrained from tilting by sleeve 36. It should be noted, moreover, that owing to the fact that the bearing of the rod 52 upon the last pin 64 is substantially in alinement with the line of drive of the fastenings, there will be no sub stantial tendency to tilt rod 52 or to force the work out of position as would occur if the support of the work were substantially out of alinement with the line of drive.
