Original No. 1,354,846, dated October 5, 1920, Serial No. 374,519, filed April 17, 1920. Application for reissue filed February 10, 1921.

To all whom it may concern:

Be it known that I, JAMEs ROBERTSON, Jr., a citizen of the United States of America, residing at Weehawken, county of Hudson, and State of New Jersey, have invented new and useful Improvements in Repair- Patches for Rubber Footwear, of which the following is a specification.

This invention relates particularly to a repair patch applicable to the toe or heel of a rubber or overshoe, and the object is to provide a patch of such form that it may be applied to either the toe or heel, and to a considerable range of models and sizes so that the repair man is under the necessity of having in hand only a limited number of different sizes of repair patches in order to be repared to repair any size or model of rub er or overshoe that may be offered. A further object is to provide a form of repair patch that may be applied expeditiously and in a substantial and workmanlike manner.

In the accompanying sheet of drawings which forms a part of this application Figure 1 is a top view of a repair patch according to this invention.

Fig. 2 is a side view of the same.

Fig. 3 is a section on the line III-III of F i 1 and 2.

Fig. 4 shows a patch applied to both the heel and toe of a rubber, the patch being in section on the line IV--IV of Figs. 1 and 3.

The repair patch is preferably a single molded piece of rubber and comprises a heavy tread portion 5 with a thickness, for example, of from an eighth to three-sixteenths of an inch so as to stand considerable wear. This thickness is such that it is comparatively inelastic. This portion is rounded at one end and is of suflicient area to cover all of the heel or as much of the sole as it is desired to cover. Upstanding from the rounded end of the tread portion is a flange 6 which curves over the tread portion. The fian e at the bottom margins 7, 7 of its ends is s arply incurved and joins to the tread portion at a distance from the margin of the tread portion. In consequence of the manner of joining the repair patch can be fitted to a. rubber or overshoe which has a heel or toe with a width equal to the distance between the points of joining of the incurved margins with the tread portion, or

which has a greater width, and the flangev can be bent'into contact with the sides of the Serial No. 444,054.

rubber when it is narrow, or, when the heel or sole 1s wide the incurved bottom margin may be rolled out to accommodate the greater wldth. When applied at the heel the upper edge of the flange will be some what stretched and the flange bent back. When applled at the toe the flange may need to be curved somewhat more than its normal form.

By reason of the flange being curved over the tread portion and also being thin, flexible and elastic it can be turned inside out and rolled under the tread, and when this is done 1t will not spring back of its own aocogd.

n preparation for ap l in the flan e is first turned under the t i'eiid and cemei it is applied to all of the surfaces of the repair patch and of the rubber or overshoe which are to come together and-the cement allowed to dry. lhe tread is then applied to the heel or sole with the flange still rolled back and after ap lying the flange is rolled up into place. fter applying any portions of the tread whlch project beyond the heel or sole are trimmed off.

1 find that because the material of the flange is thin, flexible and elastic, the incurve at the bottom margins 7, 7, though desirable, is not essential. Therefore I do not wish to hunt myself by the inclusion of this feature in the broader claims.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A repair patch for footwear comprising a tread portion rounded at one end and having a flexible and elastic flange upstanding from the rounded end of the tread portion and having the bottom margins at its ends oined to the tread portion at a distance from the margin of the tread portion and sufiiciently t in and flexible to have a bending line at its juncture with the tread portion whereby the flange can be brought into contact with the sides of the footwear when it is narrow and may be brought into contact, with the projecting margins of the tread portion to accommodate wider footwear, substantially as described.

2. A repair patch for footwear comprising a tread portion rounded at one end and having a flexible and elastic flange upstanding from the rounded end of the tread portion and having the bottom margins at its ends incurved and joined to the tread portion at a distance from the margin of the tread portion, substantially as described.

3. A repair patch for footwear comprising a tread portion rounded at one end and 5 having a flexible and elastic flange upstanding from the rounded end of the tread portion and curved over the tread portion and havin the bottom margins at its ends incurve and joined to the tread portion at a distance from the margin of the tread por- 10 tion, substantially as described.

Signed at New York, N. Y., this ninth day of February, 1921.
