REPAIR SOLE FOR SHOES Filed May 5, 1954 Oscar BR OCKMAN Patented Oct. 1, 1935 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to repair soles for shoes and has for its object the provision of an article of the class indicated, designed to be adhesively applied by those inexperienced in the art of shoe repairing.

Such repair soles are known, but have heretofore been subject to the objection that they could not be provided ready cut to fit the infinite number of shapes and sizes of shoe soles, but must be cut to fit by the home cobbler, unskilled and without proper appliances, the result being frequently unsatisfactory at least in the appearance of the finished job.

The present invention has for its object the provision of a repair sole which can be conformed to the shoe sole regardless of the shape or size of the latter, without the necessity for cutting.

A more specific object of the invention is to provide a repair sole peripherally pleated or corrugated and through the presence of the pleats being expansible or contractible to fit any shape or size.

Other objects of the invention will appear as the following description of a preferred and practical embodiment thereof proceeds.

In the drawing which accompanies and forms a part of the following specification and through- Out the several figures of which the same characters of reference have been used to designate identical parts:

Figure 1 is a bottom plan view of a shoe showing my repair sole applied thereto;

Figure 2 is a cross section showing the repair sole in juxtaposition to a shoe sole of smaller width, prior to adjustment;

Figure 3 is a similar View showing an intermediate step in the afiixing of the repair sole;

Figure 4 is a similar view showing the repair sole cemented in place;

Figure 5 is a transverse section showing the repair sole laid adjacent a shoe sole of greater width; and

Figure 6 is a similar view showing the repair sole fitted and cemented in place.

Referring now in detail to the several figures the numeral l represents the repair sole which may be of any suitable material such as rubber or composition and which is cementitiously applied to the bottom of the shoe 2 for the purpose of renewing a worn ,sole. The repair sole I is provided along its front and side margins with one or more corrugations or pleats 3 and 4. These pleats are formed by molding, in the manufacture of the repair sole, or in any other suitable manner. The corrugations 3 and 4 permit the sole to be expanded or contracted and by pressing in or pulling out the corrugations more at one point than another, the repair sole may be made to conform to any variety of shape. Thus one single size of repair sole may be made to fit a 5 large number of sizes and shapes of shoe sole. This greatly restricts the number of sizes which a dealer must keep in stock.

In applying the repair sole to the bottom of a shoe, it is customary to have the repair sole l0 terminate a short distance back of the edge of the shoe so as to prevent the feather edge of the repair sole being raised or loosened by scuffing. Figure 2 shows an instance in which the selected repair sole l is larger than the shoe 15 bottom 2. A coating 5 of cement having been applied to the entire underside of the repair sole, it is placed upon the shoe bottom and prior to pressing the middle portion 6 in place, the margins l are pushed in an even distance 8 all 20 around the shoe. After the margins 'l have thus been accurately located, the middle portion 6 is pressed down into adhesive contact with the shoe bottom. The corrugations 3 and 4 conform themselves compensatingly to the width of the space 25 remaining between the margin 1 and the middle portion 6, as indicated in Figure 4, the apices of the corrugations constituting a. part of the tread surface.

In Figure 5 the repair sole 9 is in its normal 30 state much too narrow for the shoe sole with which it is to be associated. In this instance the margin 1 is drawn out to the uniform and required distance with respect to the edge of the shoe sole, the corrugations 3 and 4 being expanded until they have virtually disappeared.

It is obvious from the above that the invention imparts great versatility to the repair sole, inasmuch as it can be made to fit any shape or size of shoe without cutting and that a single size of repair sole is adaptable to a wide range of sizes of shoe.

It will be understood that the number of pleats or corrugations is altogether immaterial 5 to the invention, the primary function of said pleats or corrugations being as a reservoir of material which can be drawn upon for increasing the peripheral dimension of the repair sole, or utilized to receive excess material when the 50 size of the repair sole must be constricted.

In addition to functioning as a means for varying the size of the repair sole, the corrugations play the important part of a marginal yieldable tread surface, thus greatly enhancing the com- 55 fort of a shoe equipped with the repair sole of my invention.

It will be understood that the details of construction as illustrated and described are mere 5 1y by way of example and not to be construed as limiting the scope of the invention as claimed.

What I claim is: 1. Repair sole comprising middle and marginal portions, said sole being pleated in a zone between said middle and marginal portions, the

pleated zone paralleling said marginal portion.

2. Repair sole comprising middle and marginal portions, said sole being provided with concavo-convex ridges between said middle and marginal portions and paralleling the latter portion.
