HMORSESHOE.

SPECIFICATION forming part of Letters Patent No. 236,353, dated January 4, 1881.

Application filed April 8, 1880.

To all whom it may concern:

Be it known that I, JOHN K. ONEIL, of Troy, in the county of Rensselaer and State of New York, have invented an Improved Horseshoe 5 and I do hereby declare that the followingis afull and exact description thereof, reference being had to the accompanying drawings, making part of this specification Figure 1 being a view of the under side of the shoe with my improvements; Fig. 2, a front view of the same; Fig. 3, a vertical section in a plane indicated by the line 00 m, Fig. 1; Fig. 4, a vertical section in a plane indicated by the line 3 y, Fig. 1; Fig. 5, a partial horizontal section in a plane indicated by the line z 2, Fig. 3.

Like letters designate corresponding parts in all the figures.

Let A represent the body of the horseshoe, B the front or toe calk, and O O the heel-calks.

The first feature of my invention consists in an improved means of attaching the toe-calk to the body of the horseshoe, whereby security, strength, and durability are attained, and the calk can readily be removed while the shoe remains on the horses foot for sharpening. and as readily be reattached. A socket, D, is formed on the under side of the toe of the s 106 to receive and inclose the shank a of the calk. The socket extends horizontally back from near the front edge of the shoe, being preferably, but not necessarily, narrowed or tapered from the entering end to the other, so that the shank of the calk, having the same form, may wedge tightly into it, and the edges might be dovetail in form; but this is no part of my invention. The calk-shank is inserted from the front till the front of the calk is about flush with that of the body of the shoe. A part of the thickness of the socket is or may be taken from the thickness of the shoe-body, and, in fact, the under covering-bar, b, of the socket maybe all taken from the thickness of the shoe-body, so that little or nothing is added to the weight of the shoe in making the socket, and the bar of the socket projects as little as possible from the under surface of the shoe. This construction also enables me to adopt my peculiar mode of fastening the toe-calk in the socket, which is another feature of my invention, and is substantially as follows:

A cross-groove, c, is formed in the lower (Model) surface of the shank of the toe-calk, as. shown in Figs. 1 and 3, and side holes, d d, are made into the socket to give entrance to a crosskey, E, for holding the calk by resting in the groove 0. To retain this key securely in place it is made flexible, so that its ends will sink into depressions ff in the body of the shoe, outside of and under the holes d d, and the lower surface of the key is rounded or chamfered at the ends, or essentially only at the rear entering end, as atg, Fig. 4, so that to withdraw the key the end must be forcibly made to rise over the sloped end h of the depression f. Anotch or catch, 2 may be formed in the upper surface of this projecting end of the key, to enable asuitable instrument to take hold of the key for withdrawing it. This construction, besides securely holding the key in place, also sinks it within the under surface of the shoe-body, so that it will not be injured by striking anything or worn off by abrasion.

The next feature of my invention consists in a peculiar form of heel-calk, O, substantially as represented. The lower extremity is composed of two sharp edges, lm, crossing each other, with notches or depressions between adjacent edges. This construction, while equally sharp, to hold from slipping, as a straightedged calk, furnishes a greater length of bearing-edge, to prevent too much indentation in pay'ements, ice, 850., also is equally effectual against slipping in all directions, and it also enables the calk to be quickly and easily sharpened by filing in the notches.

The mode represented for securing the heelcalks in the body of the shoe is as follows: The shank n of the calk, whether round or square, is somewhat tapering, and it fits into a corresponding socket or hole through or in the body of the shoe tightly by being a little too large for the socket, so that it does not enter therein quite to the shoulder of the calk. Thus every step of the horse tends to tighten rather than loosen the calk in place. Then a cross-groove, p, is made in the calk-shank, as shown in Fig. 5, and a cross horizontal hole, 4', is made through the body of the shoe, coinciding with the cross-groove 12. One end, preferably the inner end, of this hole is extended laterally, as at s, and a nail or key having been driven from the other side of the shoe-body through the hole and in the crossgroove 12 of the calk till the inner end thereof projects through, say, a quarter of an inch, more or less, then this end is clinched down into the groove or depression 3. The key or nail is preferably crosscut or otherwise roughened on the sides to obviateany tendency to work loose or out.

It may be here stated that my improved means of securing the toe-calk to the shoe is not confined to the construction described of a complete inclosing-socket for holding the shank thereof, since it may only partially cover the under side of the same, with a good but not so perfect a result.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the toe-calk B, provided with the shank a, and the horizontal socket D of the shoe-body, substantially as and for the purpose herein specified.

2. The combination of the key E with the socketed horseshoe-body A and toe-calk B, the said hey being arranged to fit in holes 01 d in the sides of the socket D, in depressions ff of the body, and in a cross-groove, c, of the toe-calk, substantially as and for the purpose herein specified.

3. A heel-calk, 0, formed With cross-edges l m, substantially as and for the purpose herein specified.

The above specification signed by me this 17th day of December, 1879.

JOHN K. ONEIL.
