SPECIFICATION forming part of Letters Patent No. 339,953, dated April 13, 1886.

Application filed February 8, 1886. Serial No. 191.139. (No model.)

To all whom it may concern:

Beit known that I, GEORGE \VATKINSON, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in India-Rubber Boots or Shoes; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked there on, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, 1n-

Figure 1, a face view of the sole complete; Fig. 2, a longitudinal central section of the same.

This invention relates to an improvement in soles for indiarubber boots or shoes.

In the usual manufacture the sole is molded with the heel and tap-sole as an integral part of the principal sole.

In the wear of the boot or shoe the rear of the heel wears away more rapidly than any other portion of the boot or shoe. To avoid this wear, pieces of metal have been introduced at the rear portion of the heel to form a hard wearingsurface at that point; but as these metal pieces are necessarily thin and attached by some device to the heel, they are liable to break or pull away, so that they become a source of very great annoyance, and are practically objectionable.

The object of my invention is to provide against the extra wear of the shoe at this point; and it consists in forming upon the surface of the heel at the rear a raised portion integral with the heel itself, as more fully hereinafter described.

In the illustration I show a single sole complete, main sole, tap-sole, and heel'in one continuous integral piece. These soles are pro- 40 duced either by rolling a continuous sheet and cutting therefrom or may be by molding individual soles.

Upon the face of the heel and at the rear I form a segment-shaped projection, a, the outer 4 5 edge of this projection corresponding to that of the outside of the heel proper. The shape of the inner edge is immaterial; but preferably I make it ofa corresponding shape to the outer edge. Thisprojection extendspartiallyaround the heel, and so that in walking this projection first meets the ground, and therefore takes the wear incident to such first contact, and being made as anintegral partof theheel it cannot tear away, does not materiallyinorease 5 5 the weight of the shoe, that portion of the heel except as to this projection being the same as in the usual construction, and the cost of production is not increased to any considerable extent, but the wear of the shoeiat the heel is very greatly increased by such extension.

In standing the heel takes a bearing at its front edge and upon the projection a, as indicated by the broken line, Fig. 2, so that the heel gives a firm support and bearing to the foot, substantially as if it presented a flat face throughout.

I claim- A rubber boot or shoe the heel of which is provided with the projection a upon its face at the rear, the said projection being made an integral part of the heel, substantially as described.
