2 Claims. (Cl. 3622) The present invention relates to shoes and more particularly to insoles constructed so as to facilitate and reduce the cost of shoe manufacture.

The insole of the present invention is of the type disclosed in my United States Patent No. 2,632,259 issued to the assignee of my instant application, and the primary object of my present invention is to provide an insole which has all of the advantages of the insole shown and described in said patent and is moreover of such construction that it can be more easily and inexpensively produced. This object and objects ancillary thereto will be more fully explained in the following description considered in connection with the accompanying drawings which are illustrative of the best modenow contemplated by me for practicing this invention.

In the drawings:

Fig. 1 is a plan view of the top of an insole embodying the present invention;

Fig. 2 is a plan view of the bottom of said insole;

Fig. 3 is a sectional view, on a larger scale, on the line III-III of Fig. 1;

Fig. 4 is a transverse sectional view illustrating the manner of stitching the upper to the insole;

Fig. 5 is a transverse sectional view of a shoe which is made with an insole of the present invention, the outsole being shown in dotted lines.

The shoe, the insole, and the method of attaching the insole to the upper are the same, with the exceptions hereinafter referred to in respect to the insole, as in my above mentioned Patent No. 2,632,259. According to my present invention, however, the insole is not slit along the longitudinal median line and is not slit between its opposite faces as in said patent, and yet can be opened as illustrated in Fig. 5 of said patent so as to faciiltate the stitching of the marginal edge portion of the upper to the marginal edge portion of the insole, as described in said patent.

Referring to the accompanying drawings in detail, the insole 1 is provided with a slit 15 disposed between the peripheral edge of the insole and the longitudinal median line thereof, and as here shown is disposed mainly near one side edge of the insole, preferably the inner side edge 16 and extends also continuously around the toe and heel portions 17 and 18 respectively to the points A and B adjacent to the opposite or outer side edge 19 of the insole. It will be understood that the insole is continuous and not slit between the points A and B. As clearly illustrated by the drawings, especially Figs. 1 and 3, the slit 15 is a bevel cut and the insole portions at said slit are beveled and overlap each other. Preferably, as illustrated in Fig. 3 the slit 15 has an upper part 15A adjacent the upper surface of the insole arranged at right angles to said surface so as to accentuate the interfit of the parts of the insole at slit 15, as will be readily understood. If desired however slit 15 may continue in uniform angular relation for the full thickness of the insole, although the right angular portion 15a is preferred, as stated. The

2,726,462 Patented Dec. 13, 1955 heel and toe portions of the insole adjacent slit 15 are radially slit as indicated at 7 and 7 and also a portion of the marginal edge of the insole adjacent the slit 15 forwardly of the ball line is also provided with a plurality of radial slits as shown at 7 It will be understood that the slits 7 7 and 7 render the marginal edge portion of the insole adjacent slit 15 more flexible than it would be without said radial slits and thereby facilitate opening of the insole, as in Fig. 5 of my above mentioned patent, so as to facilitate the stitching of successive marginal edge portions of the upper 8 to the marginal edge portion 20 of the insole completely around the latter.

It will be understood that the marginal edge portion of the upper 8 may be cemented to the marginal edge portion of the insole, instead of being stitched thereto, or both cementing and stitching may be used. Fig. 4 illustrates generally the relative positions of the insole and the upper and the parts of the insole during the securing operation, and Fig. 5 illustrates the relative position of said parts after the upper and insole are secured to each other. The portions of the insole adjacent the slit 15 are cemented to each other after the upper is stitched to the insole, and thereafter the outsole 0 shown in dotted lines in Fig. 5 is secured in the usual way. It will be noted that the slit 15 is located near the side edge of the finished shoe, substantially clear of the main part of the bottom of the wearers foot, and further in this connection it will be observed that the insole 1 is substantially continuous and presents a smooth surface to the wearers foot for substantially the full width and length of the insole. If desired however a sock lining (not shown) may be provided in the shoe so as to cover the edge of the slit 15.

In making the shoe according to the present invention, both the insole and the upper are each cut to the size and shape that they are to have, respectively, in the finished shoe, as described in my above mentioned patent, and no lasting operation is required, except that a last or form may be, and preferably is, inserted in the shoe after the insole and upper are secured to each other, whereby to facilitate the attachment of the outsole and the usual shoe finishing operation.

While I have shown and described the preferred embodiment of my invention, it will be understood that various changes may be made in the present invention without departing from the underlying idea or principles thereof within the scope of the appended claims.

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

1. An insole for a shoe, having a main part and a longitudinal marginal part integral with said main part, said parts having adjacent complementary edges extending along a longitudinal line disposed between the longitudinal median line of the insole and the adjacent longitudinal side edge'of the latter, said complementary adjacent edges being united at their adjacent ends, respectively, but being separable and movable apart from each other between their ends for the full lengths thereof, said insole also having a toe portion provided with complementary meeting edges continuous with said complementary longitudinal edges and extending to a point at the opposite longi tudinal side edge thereof.

2. An insole for a shoe, having a main part and a longitudinal marginal part integral with said main part, said parts having adjacent complementary edges extending along a longitudinal line disposed between the longitudinal median line of the insole and the adjacent longitudinal side edge of the latter, said complementary adjacent edges being united at their adjacent ends, respectively, but being separable and movable apart from each other between their ends for the full lengths thereof, said insole also having toe and heel portions provided with complementary meeting continuous witli said complementary longitudinal 1,592,751 edges and extending. to terminal points, respectively, at 2,123,567 the opposite longitudinal side edge thereof. 2,411,850 2,632,259
