INSOLE.

Application filed February T 0 uZZ 'UFIVLOIIL it may concern:

Be it known that l, HENRY MoMAs'rnR, a citizen of the United States of America, residing at Highland Park, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Insoles, of which thefollowing is a specification, reference being had therein to the accompanying drawings. I

In uniting the uppers to the soles of shoes, there is usually formed a ridge within the shoe along the meeting. angle of the upper and sole, particularly in welt work, and in practically all constructions after considerable wear, this edge portion of the sole is considerably higher than the central portion. To give a smooth inner surface, a sock lining or insole is usually provided, but after a time the margin of this insole will our]. upwardly and inwardly due to the raised portion of the sole and to the dampness of the under side of this margin caused by lack of ventilation. This inwardly curling edge often causes great discomfort to the wearer.

Separate, detachable insoles as commonly constructed, will, in a like manner curl upwardly and inwardly along their margins, due to the same causes, and it is the object of this invention to provide an insole or sock lining which is so constructed as to prevent this curling of its edge portion and will always present a smooth upper surface within the shoe across the entire width of the sole.

With these and other ends in view the invention consists in the matters hereinafter described and more particularly pointed out in the appended claim reference being had to the accompanying drawing, in which Figure 1 is an inverted plan view of an insole or sock lining embodying the invention;

Fig. 2 is a transverse section of the same substantially on the line of Fig. 1;

Fig. 3 is a perspective view of the same with the upper ply turned back to more clearly show the construction;

Fig. 4 is an enlarged transverse section of a shoe sole with the upper secured in place thereon in the usual manner, and a detachable insole embodying the invention in place upon the shoe insole within the shoe;

Fig. 5 is a perspective view of a modified construction of insole showing the bottom facing of the insole detached and turned Specification of Letters Jiatent.

back to disclose a padding interposed between this facing and the upper portion or body of the insole; and

Fig. 6 is a transverse section of a shoe with the modified construction of insole shown in Fig. 5 applied thereto.

The socklining or insole embodyin this invention consists of a sheet or body of leather or other suitable material which is cut so that its margin will conform closely to the shape of the sole of the shoe within the upperthereof, with the edge of the insole lying close to the wall of the upper along the entire length thereof. A marginal portion of this body A is cut away as at 1 for a distance inwardly from the edge of the body at the lower or underside thereof, or the body may be formed of two or more layers of material 2 and 3 as illustrated in Fig. 2, the lower ply 3 having the same outline as the upper ply 2 but of less width so that the edge channel or groove 1 is provided in the lower face of the body along its edge, leaving the thin edge portion 4 of the layer 2 to overlie the welt 5 and attached and inturned edge of the upper 6 or other ridge or projection which may be formed by the attachment of the upper to the sole of the shoe. The ply 3 forms a thickened central portion for the body so as to hold the ply 2 level with its thin edge portions l adjacent the wall of the upper, the channel or groove 1 forming, when the insole is in place within the shoe, an air channel 7 all along the margin of the insole adjacent the upper. The pressure in use, comes upon the central portion of the insole and because of the thin lip or margin 4c with the open channel beneath it, there is no tendency of the lip 4: to curl upwardly and inwardly, and this curling is also prevented by the channel 7 which forms an air passage providing ventilation to keep the underside of this thin lip 4 from becoming more moist than the upper surface thereof.

As shown in Figs. 5 and 6, the central portion of the body of the insole may be increased in thickness by providing a padr8 therein of any suitable material such as felt, this pad being interposed between a comparatively thick upper ply 9 and a thin lower ply 10 or surfacing which is of lesser width than the ply 9 to provide a marginal groove 11 along the underside of the insole. This marginal groove may extend only r margin presenting a COIltIIlUOHS smooth upalong the edge of the toe portion of the insole, as shown, or it may extend along the entire margin thereof.

A sock lining or insole constructed as described, may be incorporated in the shoe it- Self, being secured to the sole in any desired: manner or it may be used as a separate detachable insole which may be applied to any shoe with the thick central portion per surface eXtendi-ng-acrossthe entire width of the shoe,=w1th anopen' V6I'1t1lat'1 Ilg" Ol1LI1 thewall' of the upper.

nel beneath t his thin lip" or margin along 1 Obviously, changes may be made in the 7 construction of the device without departing from the spirit of the invention andI-do not therefore wish to limit myself to the spe cific construction and arrangement shown.

WhatI claim is: g r A separate detachable inner sole comprising a body formed ot upper and lower thicknesses of material with a padding interposed between said i thicknesses, the lower thickness being of less width and length than the upper thickness to provide a margin of a single thickness andrt'he area of the padding being less than the area of the lower thickness of material to providea cushion at the central" portion of thebody only, said paddinghaving a thin margin and said upper and lower filllOkllfiSSQS of material being se cured together along their contacting mar ginalportions outside of said padding.

ln testimony whereof I aiiix' my signature in the presence of two 1 witnesses.

I HENRY M'CMASTER.
