HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 289,330, dated November 27, 1883.

Application filed July 12, 1883. (No model.)

To all whom it may concern.-

Be it known that I, CARL F. A. ZINOKE, a citizen of Germany, residing at Hamburg, Germany, have invented new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to novel means for securing the heel and toe calks to horseshoes, as pointed out in the following specification and illustrated in the accompanying drawings, in which- Figure 1 represents an inverted plan of a horseshoe provided with my heel and toe calks. Fig. 2 is a transverse section in the plane cm, Fig. 1. Fig. 3 is a front elevation of the heelcalk detached. Fig. 4 is a transverse section in the plane y y, without the calk. I

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a horseshoe, which is provided with a heel-calk, B, and with two toe-calks, G 0. Each of these calks is provided with a tapering shank, a, which is provided with one or more keys, I). In the example represented by the drawings I have shown two keys, and I prefer to use two keys for the toe-calks and only one key for the heel-calk; but the number of the keys may be selected to suit circumstances. The tapering shanks a fit into corresponding sockets, 0, formed in the horseshoe A. The shape of one of these sockets is shown in Fig. 4, and it is obvious that the sockets must be provided with grooves or seats d, to admit the keys 1;.

In practice, the keys, the shanks, and the calks are formed out of one and the same piece of metal. Oalks of different shapes are provided for different seasons of the year.

The sockets c, with their grooves d, are

formed by means of suitable punches, and by referring to Fig. 4. it will be seen that the grooves extend throughout the entire depth of the sockets. WVhen the shanks of the calks have been driven into their sockets, the keys prevent the calks from turning. and whenever it is desirable the calks can be removed and replaced by others, so that in cold weather sharp-pointed or sharp-edged calks can be inserted Without much loss of time. This operation can be performed without removing the shoe from the hoof, since by a few sharp blows on the body of the shoe each of the calks can be made to come off, so as to make room for another.

What I claim as new, and desire to secure by Letters Patent, is-

A horseshoe provided with atapering socket and one or more rectilinear grooves extending longitudinally throughout the entire depth of the socket, in combination with a heel or toe calk provided with a tapering shank which fits the tapering socket in the horseshoe, and is provided with one or more keys corresponding to the groove or grooves in the socket, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
