ERWIN A. BURKE, or CLEVELAND, omo

To all whom may concern.- I 7 Be it known that I, ERWINA. BURKE, ac'itizen of the United States, residing at Cleveland, in the county of (Juyahoga and State of Ohio, have invented new and useful Improve ments in Soles and Welts, of which the following is a specification.

This invention relates to soles and welts for l shoes, and particularly to the means by and the manner in which an outer sole is fastened to a welt.

The object of the invention is to remove a defect incident to the present method of attaching the outer sole to the welt, and a furthe thread [to pull through the welt for the first two or three stitches, and the subsequent skived down,

working of the shoe in walking is liable to pull through still more of these stitches, and I in time the ends of the welt become detached from the sole, leaving an opening. Repeated efforts have been .made to devise a means whereby the ends of the welt would be prevented from becoming unstitched or loose, while preserving the good appearance of the parts. v Toremedy the defect indicated, I make a channel across or recess in the shank; of the outer sole before .it is sewed to the welt. This channel or recess receives the ends of the welt, which, instead of being are left at. their original thick? mess. The c'hannel'or recess has at the heel end a depth equal to the thickness of the leather used in the welt, and the channel is tapered or inclines upwardly and forwardly until it comes to the natural surface'of the leather. To give a neat job, the channel should be at least three-fourths of an inch wide, gradually decreasing in depth forwardly, or from the heel toward the toe. As said before, the welt is not thinned down at the ends, but is left its original thickness, and when placed in position the. ends of the welt come against the rear shoulder or edge of the channel or depression, and when stitched on the machine the threads go through the en- Specification of Letters I atent.

tire thickness of thewelt. The sol is of suflicient thickness to hold the threads without danger of pulling out, and so are the ends of the welt, and there 1s no chance of the threads pulling. out of either, as in the old method, wherein, as said before, the ends of thewelt are thinned down to an edge. Also by my invention the labor of skiving the ends of the weltis dispensed with, thereby saving labor and reducing the cost of manufacture. The ends of the welt being of the original thickness-that is, the same thickness as the rest of the welt-a stronger construetion' results, and there'is'no-danger of the shoe opening up between the welt and the.

Full strength of the'welt is retained and a neater and more durable job is produced.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan View of the back or top of an outer sole before the same is applied to the welt. Fig. 2 is an edge View of the same.

Fig.3 is a plan view of the outer sole with the welt'in place, the upper and insole being removed for the sake of clearness. Fig. 4 is an edge view thereof. Fig. 5 is a plan view illustrating amodification.

Inthe drawings the outer sole is indicated at 6, and 7 indicates a channel cut across the same in the top or backthei'eof. At the rear edge this channel has a squareor blunt shoulder 7, and the channel gradually decreases upwardly and forwardly therefrom until it merges withthe surface of the sole at 7".

The welt is indicated at 8 and is firstsewed to the upper and insole. The outer sole 15 then sewed to the welt, with the ends thereof fitting or abutting against the shoulder 7 "2 These ends are of the'same thickness as the body of they welt, and the channel 7 is of proper depth to receive the same. Thesole is stitched to the welt, the stitches indicated at 9 covering the joint between the ends of the welt and the sole at 7". It will be seen that by retaining the original thickness at the ends of the welt the threads are not liable top'ull out, as when the ends are skived down to a sharp edge.

In the modification shown in'Fig. 5 instead of cutting a channel across the sole triangular incisions or depressions are cut in the sole on eachside thereof, as indicated at 10. These incisions have a shoulder at the rear end and taper-upwardly and forwardly in similar man: ner to the channel 7, and the welt is let into these depressions and sewed through in the 5 outer sole sewed theretosame manner as above described with respect to the other construction.

It is much less labor to cut a channel 7 across the sole than it is-to skive down the ends of the welt.- The invention therefore results in a saving of labor and time in addition to the other advantages referred to.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a welt shoe, an outer sole having in the shank thereof a recess of increasing depth toward the rear of the sole, adapted to receive the ends of the welt.

2. Ina shoe, 9. welt with blunt ends, and an having a depression in the shank, of increasing depth toward the rear, into which depression the ends of the welt fit.

3. In a'shoe, an outer sole having a depres sion in the shank with a shoulder at the rear, and a welt towhich the said sole is sewed, said welt having .blunt ends which fit in the depressien and abut against said shoulder.

. In testimony whereof Ihave signed my name to this specification in the presence of two sub 5 scribing witnesses.
