Application filed July 21, 1922. Serial 160. 578,509.

To all whom it may concern:

Be it known that I, EUCLID 1. LA CHA- PELLE, a citizen of the United States. residing at Brockton, in the county of Plymouth and Commonwealth of Massachusetts, have invented certain Improvements in Methods of Preparing Outersoles for Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification.

My invention relates to outersoles for boots and shoes and more particularly to outersoles having greater elevation at one lateral side than at the opposite lateral side.

The foot, generally speaking, has the tendenoy to roll toward the little toe side of the boot or shoe and, in due course of time, is thereby weakened. My invention has for object the provision in outersoles for boots and shoes of a raised portion over the plane surface thereof to counter-act this objectionable tendency and to cause the foot to tread in" the center of the boot or shoe bottom and to cause the weight of the body to be mainly supported upon the great toe and upon the ball back of the great toe while the heel is lifted in the act of walking.

With this aim in view, 1 have invented the herein disclosed method invention, which is primarily intended for use on leather but which may be adapted to material other than leather.

In the drawings:

' Fig. 1, is a plan View of an outersole for a boot or shoe embodying my invention.

Fig. 2, is a transverse sectional view of the outersole shown in Fig.v 1, illustrating more particularly my novel method step of forming a raised portion at one thereof.

Fig. 3, is a sectional view taken on line 33 of Fig. 1, illustrating more particularly a filler contained in the cavity of the outersole shown in Fig. 1.

Fig. 4, is a plan view similar to the one shown in Fig. 1, but with a fabric cover strip shown as applied to the outersole over the filler in the cavity.

Fig. 5, is a sectional view taken on line 55 of Fig. 4.

Fig. 6, is a perspective view of the outersole shown in Fig. l.

In Fig. 1. the outersole 1, is shown with a cavity 2, formed therein under the influence of the force applied to the plane surface of the outersole in the ractice of my tnethod invention. In Fig. 2, the outersole is shown as having been formed with a bevel raised portion 3, under the influence of the forcing action of the moulds 4t and 5, and as shown, thesaid bevel raised portion is located within the marginal portion 6, of the outersole, which marginal portion is intended for receiving the fastenings required in the process of uniting the outersole to the shoe. In Fig. 3, is-shown a sectional view similar to that of Fig. 2, but with the addition of a filler 7, shown as applied into the cavity in the outersole, and whichserves to retain the bevel raised portion of the outersole in raised condition during wear and which is preferably held into the cavity by cementitious material. In Fig. 5, is shown a sectional View taken on line 55 of Fig. 4, illustrating a fabric cover strip 8, which is applied to the outersole over the filler in the cavity and which is held thereto preferably by cementitious material. whereby the filler is held into the cavity during wear, and, as shown, extending fromside to side of the outersole over the marginal portion 6, so that the fastenings required in the process of, uniting the outersole to the shoe will pass through the same to positively hold the filler in the cavity during wear.

In Fig. 4-, is shown a plan view similar to that of Fig. 1, illustrating the outersole 1, the cavity 2. containing the, filler over which is applied the cover strip 8. In Fig. 6, is shown a plan view similar to that of Fig. 1, illustrating the reversed side, or outside plane surface of the outersole, the bevel raised portion 3, and the edge of-the fabric cover strip '8, located on the opposite plane surface of the outersole.

lhe outersole, as herein shown, is in the form adapted to welt shoes, it being rough rounded to the shapeof the shoe once having been laid on the shoe, but it must be appreciated that my invention is ado) table to and is intended for outersoles embo ying the shape of the shoe prior to being incorporated into the shoe such as ordinary outersoles for McKay shoes.

In the case of such outersoles as leather outersoles, water, or other liquid, is preferably ap-plied and thereafter, while the outersoles are under the effect of the liquid, (preterably while in temper) force is applied to one side by means of moulds, as herein shown, or by other suitable means, whereby the plane surface at one of the lateral sides of the outersole (preferably at the little toe cover strip, which is preferably of fabric, is i applied over the outersole and over the filler in the cavity.

ll am well aware that, for the same purpose as herein contemplated, it is old in the art of shoerepairing to form by hand and unite to the little toe sides of outersoles of boots and shoes by means of nails or stitches bevel shaped patches, corresponding to the herein shown bevel raised portion 3, integral with the outersole 1, (see Fig. 6) and it is the sole purpose of my present invention to improve upon the mode of uniting such bevel shaped patches to outersoles by integrally embodying the same in outersoles, and my invention is thus limited and the claims are to be interpreted to forcing on a bevel the plane surface of a sole to form thereby a beveled surface corresponding, in length and width, substantially to the bevel shaped patch common to the art of shoe repairing. Extending approximately from the toe-end to the ball-line and from the edge to the middle longitudinal line of the sole, for the purpose of causing the wearer of the boot or shoe to tread on the center of the sole; and the novel construction of the mould 4:, (see Fig. 2) is adapted to and intended for such integral embodiment.

As herein shown, the bevel raised portion 3, is formed inwardly of the marginal portion of the outersole, so that uniformity in heft of outersole edge will exist at both sides of boots and shoes. Experiments have shown that the said bevel raised portion should be about three sixteenth of an inch at its thickest part. Furthermore, the outersole should be laid on a shoe for best results so that the said bevel raised portion will be in close proximity to the finished bottom edge of the shoe.

The term outersole, occurring in the memos specification and in the claims must be interpreted to include a 'half outersole in the form of a tap, as well as a full outersole. The term shoe, occurring in the specification and in the claims, must be interpreted to include the term boot.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: v

1. The method of preparing outersoles for boots and shoes, which consists in forcing on a bevel the plane surface of an outersole at one of its lateral sides above the plane surface of its opposite lateral side and in the application of a filler into the cavity formed in the outersole under the influence of said forcing action, for the purposes de scribed.

2. The method of preparing outersoles for boots and shoes, which consists in forcing on a bevel the plane surface of an outersole at one of its lateral sides above the plane surface of its opposite lateral side and within the marginal portion of the outersole, in the application of a filler into the cavity formed in the outersole under the influence of said forcing action and in the application of a material over the filler in the outersole, for the purposes described.

3. The method of preparing outer-soles for boots and shoes, which consists in forcing on'a bevel the plane surface of an outersole at one of its lateral sides above the plane surface of its opposite lateral side, in the application of a filler into the cavity formed in the outersole under the influence of said forcing action and in the application of a material extending from side to side of the outersole over the filler in the outersole, for the purposes described.

4. The method of preparing soles for boots and shoes, which consists in forcing on a bevel the plane surface of a sole at one of its lateral sides above the plane surface its opposite lateral side, for the purpose of causing the wearer of the boot or shoe to tread on the center of the sole.
