SHOE MANUFACTURE Filed July 22, 1931 ATTORNEYA Patented Sept, 4, V1934A 1,972,229 sHoE MANUFACTURE Charles L. Laible, Columbus, Ohio, assignor of one-half to The Moss Corporation, New York, N. Y., a corporation of New York Application July 22, 1931, serial No. 552,431

s'claims. (cm2- 142) My invention relates to shoe manufacture, and particularly to the making of shoes having soles adhesively secured to the shoe bottoms.

It is an objectl of my invention to make a shoe without an insole by employing a turn shank with a sock lining. Thus it is my object to make a shoe having a single sole only just as a turn shoe, thereby achieving, without the expensive turning operation, a shoe with increased sole flexibility `and having greater comfort than a turn shoe.

It is an object of my invention to make a shoe which does not require channels or stitches in the sole, so that the inside is much smoother and more comfortable than shoes heretofore made.

Another object of my invention is the avoidance of the necessity of applying the sock lining after the shoe is made up, and in which the cost of the insole is eliminated.

The above objects and other objects to which reference will be made in the ensuing disclosure, I accomplish by that certain combination and arrangement of parts of which I have illustrated a preferred embodiment.

Referring to the drawing:-

Figure 1 is a side perspective view of a last showing the first step in my new shoe manufacture.

Fig. 2 is a bottom view of the last showing subsequent steps in my process.

Fig. Bis a side elevation of the last shown in plan in Fig. 2.

Fig. 4 is a side elevation of a finished shoe.

Fig. 5 is a sectional view taken along the lines 5-5 in Fig. 4.

The first operation is to secure the sock lining 1 with its inner surface against the bottom surface of the last 2. Preferably thesock lining is secured on the last with a weak cement, which will allow ready detachment and then can be readily 40 removed with a solvent so that the inside of the shoe will be clean and unstained.

The next step is the application of a turn shank 3, which may be secured in position as indicated lin Fig. l, with several tacks 4. p

The upper 5 is then stretched over the last and tacked to the last as with tacks 6. Previously cement 7 is applied to the exposed surface of the sock lining and turn shank, and after a short interval the upper will adhere tightly to the sock liner and shank.

The tacks 6 are then withdrawn and the shoe bottom is then skived o smooth, las indicated at 8 in Fig. 2. Cement is then applied to the shoe bottom, and the outsole 9 is then cemented in position.

The shoe is then put in a press to cause a rm bond between the sole and shoe. bottom. After removal from the press, the shoe is withdrawn from the last and the heel 10 is applied, and the other usual steps of finishing accomplished.

It will thus be observed that while employing some well known steps in shoe manufacture, I achieve a turn shoe effect without the expensive steps used in turn shoe manufacture.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, iszshank, then skiving said edge portions, and then i adhesively securing a sole to said edge portions and the shank.

2. The method of manufacturing a shoe wherein a sock lining forms the insole, which comprises securing the sock lining to the bottom of the last by a readily dtachable and removable adhesive, then temporarily securing a shank piece to the last over the sock lining, then applying an upper to the last and adhesively securing its edge portions to the sock lining and the shank, then skiving said edge portions, and then adhesively securing a sole to said edge portions and the shank.

- 3. The method of manufacturing a shoe wherein a sock lining forms the insole, which comprises securing a sock lining to the bottom of a last by temporary means, then securing a turn shank' to the last over` the sock, lining by temporary means, then applying an upper to the last and adhesively securing its edge portions to the sock lining and shank, then skiving said edge portions, and then adhesively securing a sole to said edge portions of the upper and-to the shank.

4. The method of manufacturing a shoe wherein a sock lining forms the insole, which comprises securing the sock lining to the bottom of a last, then securing a shank on the last in overlapping relationship with the sock lining, then applying an upper to the last andadhesively securing its edge portions to the sock lining and the shank, then skiving said edge portions, and then adhesively securing a sole to said edge portions and shank.

5. The method of manufacturing a shoe which comprises securing upon a last a limp insole member and a stiff shank piece in overlapping position, then applying an upper to the last and adhesively securing its edge portions to the insole member and shank piece, beveling said edge portions, and adhesively securing a sole to the edge portions and shank piece.
