IMPROVED BOOT-HEEL To all whom it may concern:

Beit known that we, FRANCIS D. HAYWARD, of Malden, and PASGHAL STONE, of Charlestown, in the county of Middlesex and State ot' Massachusetts, have invented'a new and useful Improvement in Heels for Boots or Shoes; and we do hereby declare the same to be fully described in the following specication and represented in the accompan yin g drawings,of Which- Figure 1 is a transverse section'ot a heel provided with our invention. Fig. 2 is a top View of the lower portion of such heel; Fig. 3, an under-side View of the upper portion. Fig. 4 is a transverse section of a heel exhibiting the invention in a modified form.

The object of our invention is not only to enable the wearing-lift or trend portion ot' a' heel to be readily removed from and replaced and xcd upon the remainder of the heel, but to allow the said wearing or tread litt or portio'n to be revolved on the rest ot' the heel, as occasion may require, in order to equalize the wear on such tread 'lift or portion. For this purpose we make the heel in two parts,v and either or both of them maybe, in part or in Whole, of india-rubber or an elastic composition, in which caoutchouc may' constitute a constituent; and, furthermore, We form such parts with a dovetail connection, one or both parts otwhich-that is to say, thc dovetail and its socket, or the material immediately next to and around the said socket-should be elastic, in order that the parts ofthe connection may be sprung together orapart from one another, as circumstances may require.

In the drawings, A is that part of the heel which is fastened to and projects from the sole `of the shoe or b oot, and Bis the movable and rotary portion, which is secured to the part A by an elastic dovetail connection.

The dovetail is shown at a and its socket at b. The dovetail may project from the post B, and the so'cket be made in the part A, in manner as shown in Fig. 1; or the dovetail may extend from the partAand into the socket made in the part B, as shown in Fig. 4, both dovetail and socket being circular in horizontal section, in order that the part B may be rcvolved While in connection with the part A. The dovetail a, or the part containing the socket b, or both, should be ot an elastic material, in order that the dovetnil maybe sprung into and out ofthe socket.

The dovetail and socket may be polygonal in section, so long as the section is a regular polygon, in which case the part B, although not capable of being revolved While in connection with the part A, may be removed therefrom and be turned more or less, and aftcrwanl be replaced ou the part A, the same beingr to bring a different portion ofthe surface of the tread into wear, in order that the Wear on the tread may bc dovetailed over it, or the tread-lift he prevented from always wearing down in one place. l/Ve prefer, however, to make thc dovetail connection circular, as well as elastic, in either the dovetail or its socket, or both. When made as above described it will be an ensy matter to either separate the ilovetail from or insert it within its socket, the elasticity oi' the one or the other, or both, as the case may be, serving to hold them in connection under ordinary circumstances.

We do not claim a heel composed ot" two parts connected by a dovetail and its socket; but

The improved heel or parts AB, as iliade with the dcvetail connection, elastic, as dcscribed, or with the circular or polygonal elastic dovetail connection, as explained, the whole being so that the tread part B may beeither revolved or adjusted relatively' to the part A, substantially as and for the purposes specitied.
