Specification of Letters Patent.

Patented Mar. 14, 1922.

Application filed. January 17, 1921. Serial No. 437,769.

To (ZZZ whom it may concern:

Be it known that I, SILvIo A. GIZZI, of the city of Niagara Falls, county of lVelland, Province of Ontario, Canada, have invented certain new and useful Im provements in Pads for Shoe Soles, of which the following is a specification.

This invention relates particularly to pads or lifts adapted to be applied to the soles of shoes to increase the thickness of the sole at any desired point at which it may be desired to give increased wear or for orthopaedic purposes, and it is my object to provide a pad which may be easily apphed and held in place with very few nails.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which Fig' 1 is a plan view of the under side of the sole of a shoe showing my improved pad in position;

Fig. 2 an enlarged plan view of the upper side of the pad;

Fig. 3 a side elevation of the same; and

Fig. 4 a cross section of the same.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

The pad will be formed of any suitable resilient composition such, for example, as a rubber compound possessing a suitable amount of resiliency and having suitable wearing qualities such as the material commonly employed in resilient rubber heels.

In plan the pad is lenticular as shown in Figs. 1 and 2 of the drawings, while on every line of cross section it is of ,concavoconvex form as will be understood particularly by reference to Figures 3 and 4 of the drawings. A reference to Fig. 4 will also show that a line joining the middle points of the edges lies below a line joining the extreme points of the ends. It is also preferable that the shape'be such that either edge will contact with a plane surface all along its length. The result of this form is that when the pad is placed against the surface of the sole and pressure exerted on it to flatten it out, the ends of the pad are first deflected from their normal shape so that when the pad is finally nailed down flat as shown in Fig. 1, these extreme ends are firmly held to the surface of the sole and do not tend to spring away.

Owing also to the fact that the pad is concavo-couvex on every line of cross sec-- tion, all its edges similarly hug the surface to which the pad is applied so that the nails may be few in number and relatively remote from the edges.

It will be noted that the pad is tapered to a feather edge at one side. This is the side which is nearest to the center line of the sole of the shoe, and I thus ensure that there is no abrupt transition from the sole to the pad at the inner side of the latter.

Vhile this device is particularly adapted to raise the sole of the shoe at any desired polnt, it may be also used for repair purposes under certain conditions.

It will be further understood, of course, that the shape and proportions may be considerably changed without materially affecting the mode of operation.

What I claim as my invention is:

1. A resilient sole pad for shoes of lenticular form in plan and of concavo-convex form on every line of cross section, the edges bemg shaped so that a line joining their middle points will lie below a line joining the extreme points of the ends of the pad.

2. A resilient sole pad for shoes of lenticular form in plan and of concavo-convex form on every line of cross section, the edges being shaped so that a line joining their middle points will lie below a line joining the extreme points of the ends of the pad, either edge of the pad being adapted to contact a plane surface substantially all along its length.

3. A resilient sole pad for shoes of lenticular form in plan and of concavo-convex form on every line of crosssection, said pad tapering to a feather edge at one side, the edges being shaped so that a line joining their middle points will lie below a line joining the extreme points of the ends of the pad.
