APPARATUS FOR USE IN OPERATING UPON SHOE-SOLES.

Specification of Letters Patent.

Patented Jan. 15, 1918.

Application filed April 27, 1916, Serial No. 93,893. Renewed June 8, 1917. Serial No. 173,649.

To all whom it may concern:

Be it known that we, ROBERT B. PUoKET'r and HARRY R. ABBOTT, citizens of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Apparatus for Use in Operating Upon Shoe-Soles, of which the following is a specification.'

This invention relates to the art of manufacturing shoes, and has special reference to a novel apparatus for enabling a lift to be cut from the heel-seat portion of the outer sole after the tread portion of the latter has been secured to the upper. The objects of the invention are to provide means for enabling a lift to be cut from the heeLseat por tion of the outer sole of a shoe without danger of injuring or cutting the part of the shoe beneath the sole; to rovideln such an apparatus means for enabling the heel-seat portion of the sole to be accurately positioned with reference to the cutting imple ment, or die, so thatthe opening made in the sole by cutting the lift therefrom will be correctly centered with respect to the heelseat portion of the sole and the heel to be applied thereto; and, finally, to provide adjusting means for enabling the device to accommodate singer different size.

In the manufacture of shoes as now practised, the outer sole, consisting of an integral piece of leather, is secured to the upper and then the heel secured to the heel-seat portion of the sole. The heel-seat portion of the sole is never subjected to any wear, and it has heretofore been proposed to remove a portion of this leather in the sha e of a lift which may be used as the top 11ft for a heel, and thereby secure great economy in the manufacture of shoes. In attempting to do this the lift has been cut from the heel-seat portion of the outer sole, and a filling tenon of approximately the size of the lift out, and of cheaper material, has been secured to the heel and then the heel applied in position in the usual Way after the sole has been secured to the shoe, so that the tenon will fill the space made by removing the lift. It was soon discovered that this was an impracticable method of procedure, owing to the impossibility of properly positioning the recess in the sole with respect to the tenon on the heel, so that when the heel was applied it would be exactly centered with respect to the sole.

In a companion application of the present inventors, filed January 12th, 1916, Ser. No. 71,619, it has been proposed to cut the lift from the sole after the tread portion of the sole has been sewed to the upper, and before the heel-seat portion has been nailed thereto. In carrying out this idea it was thought possible to out the lift from the sole by the use of a reciprocating die while the last was yet in the upper, thus utilizing the last to offer the necessary resistance to the die to enable the latter to cut through the sole. It was found, however, that the ordinary lasts used are not uniform in .size, even for the same style of shoe, and that frequently the die would cut through the outer sole and into the inner sole, and such method of procedure was found impracticable.

The present invention enables the above objections to be overcome and permits the lift to be cut from the sole in a simple, efficient and economical manner, as will hereinafter be described.

Referring now to the drawing Figure l is a plan view showing a shoe with the outer sole secured thereto, and in position on a novel support permittin a lift to be cut from the heel-seat portion wlthout the danger of cutting any other portion of the shoe, the view-showing the-sole with the cut lift removed;

Fig. 2 is a view in side elevation, showing a shoe in position on the improved support, and illustrating conventionally a die for cutting. the lift from the heel-seat portion of the sole; I

Fig. 3 is a view in front elevation of the improved support; and

Fig. 4 is a sectional view ofv a heel supplied with a tenon for filling the opening made by removing the lift from the outer sole.

The numeral 1 indicates a support, such as a table, or the like, on which is mounted a head 2 having yoke-members 3, which are connected at their upper end by a block 4, which is preferably cast integral with the yoke-members 3. The block 4 is flat on its upper side, and has a rounded end portion 5 projecting slightly beyond the front side of the yoke-members 3, and its under side is inclined rearwardly from said front end to the end of an extension 6 which projects a considerable distance beyond the rear sides of the yoke-members 3. The extension 6 is in the form of a plate, and at the point where it projects from the block 4 the latter provides a vertically-disposed shoulder 7. Secured on the upper side of the block 4 is a fiat, metal plate 8 which at its rear side is bent at right angles to itself, as indicated at 9, to extend over the'shoulder 7, to which it is secured by means of screws 10. The under side of the block 4 and of the plate 6 form one continuous inclined surface, as shown more clearly in Figs. 2 and 3, and indicated by the numeral 11. The numeral 12 indicates a gage-plate which is cut away to'provide a V-shaped recess from the edges of which depend guide-members 13 formed integral with said plate and converging from the forward edge and outer side thereof to a point about midway of the plate. Toward its outer end the plate 12 is provided with slots 14 which are adapted to loosely receive the screw-threaded ends of set screws 15 which pass through apertures 16 formed in the rear end of the plate 6, the screw-threaded ends of said screws being received in screw-threaded apertures formed in the outer end of a nut plate 17 In proceeding according to the present invention, an outer sole 18 is stitched to the upper in the usual way, as indicated by the row of stitching 19, leaving a heel-seat portion 20 free, that is, unconnected with the upper. The operator places this heel-seat portion on the plate 8 and places the shoe between the yoke-members 3, its heel-portion engaging the inclined side 11 of the block 4, and being guided to a true central position by the guide-members 13, which also act to limit the inward movement of the shoe. A die 21, which is shown removably secured in a holder 22, is thenreciprocated in a defined path, as bya plunger 22 in any preferred way to cut a lift from the heel-seat portion 20, in which operation the cutting edge of the die will pass through the outer sole and engage the plate 8 which is preferably of soft metal. The cutting of the lift provides an opening 23 in the heel-seat portion of the sole, which is correctly positioned with reference to the heel portion of the shoe. When the shoe is removed from the block 4 the lift is carried with it and is then easily removed by hand. The heelseat portion of the outer sole is then nailed to the counter and inner sole of the upper in the usual way, after which a heel 24, provided with a tenon 25, is applied to the outer sole, the tenon filling the opening 23 made by removing the-lift from the sole. By

loosening the set screws 15 it is obvious that the gage-plate 12 may be adjusted to permit the guide-members 13 to properly position varying sizes of shoes.

From all of the foregoing it will be readily appreciated by those skilled in the art that by the use of the apparatus herein described a lift may be cut from an outer sole in such manner that when the heel having a filling tenon thereon is applied to the sole the heel will be correctly positioned or centered with respect to the latter.

It is, contemplated that the plunger 22 will form part of a suitable machine whereby the die 21 may be given a single reciprocation at the will of the operator for cutting the lift when successive shoes have been adjusted to the proper position on the support. Such machine, however, forms no part of the present invention, and we have merely shown, more or less conventionally, a guide 26 in which the plunger 22 reciprocates, and which causes the same to move in a defined path with respect to the plate 8 on the block 4.

We claim:
