HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 296,996, dated April 15, 1884.

Application filed November 12, 1883.

l splines, which are intended to iit closely in T0 @ZZ whom t may concern,.-

Be it' known that I; HoLooM OLsoN, a citizen of the United "States, residing at Mariadahl, in the county of Pottawatomie and State of Kansas, have invented certain new and ,use ful Improvements-in Horseshoes, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to horseshoes; and the object I have in view is to provide the shoe with heel and toe calks, which may be removed readily while the shoe is on the foot of the horse. for the purpose of sharpening or renewing said calks.

In the accompanying drawings, making a part of this specification, Figure l represents a sectional view of a horses hoof with my improved shoe secured thereto. Fig. 2 is a front view of the shoe detached. Fig. 3 is a sectional view of the heel of the shoe at one side. Fig. 4 is a detached View of a screw that I use in securing the toecalk in place. In Fig. 5 I show a perspective of one heel of the shoe and also a perspective of the calk which is to be secured thereto.

In the figures, A represents al horseshoe, formed in any of the well-known and usual ways upon its upper or inner face. This shoe has a ange, B, around its outer edge, on its under side, such as is frequently used upon winter shoes, and this ange, together with a small portion ofthe body of the shoe, is cut away at the toe, so as to form a dovetailed recess to receive a correspondingly shaped tongue, d, upon the toe-call; D. Thetoe-calk.)l

has an extension, c, rearward, which lies against the under side of the toe of the shoe,`

and is secured thereto by means of a screw, E, which has, preferably, cross-cut slot-s in its head. The outer end of this extension is turned up and then over the web of the shoe, and thus forms an additional safeguard for holding the call; in its place. Two slots, 71. and li, are formed in each of the heels of the shoe, and run longitudinally, one being vertical and the other horizontal in position. The horizontal s'lot is made at the base of the flange B, so that the bottom of the calli will have a flat bearing upon the under face of the shoe. The vertical slot is made in the shoe proper or web of the shoe.

F F represent the heel-calks, which are, of course, sharpened, as usual, for ice, sleet, &c. Upon two sides of these calks are formed (No model.)

the slots in the shoe-heels. The splines are at right angles to each other, and when they enter the grooves or slots in the ends of the shoe and the calks are driven forward with a hammer a very tight fit is effected. The calks may be secured in place by means of screws or by partially closing the ends of the slots by any suitable instrument; but as a general thing they will remain without the aid of such means. Vhen the horse is traveling forward, the pressure of the calk is forward. In stopping quickly or in backing the reverse is the case; but the curve of the shoe makes a diagonal pressure, as seen by the line m x, Fig. 5, so that the friction caused on the side of the calks and splines,together with that caused by the weight of the horse, being thrown upon the calks, prevents their backward move-A ment. Vhen a horse either stops suddenly or backs, his front feet are thrown well forward of, and his hind feet well under, his body, thus throwing his entire weight upon the heel-calks. This weight tends to clamp the calks and to produce sufficient friction upon it to keep it in the shoe.

I do not claim, broadly, atoe-calk lying against` the ,web of the shoe and having its rear extension turned up and over said web; but

W'hat ,Ido claim is- 1.A horseshoe having a downwardly-projecting flange on its under side, and having a dovetailed opening in said flange and partially in thetoe of the shoe, in combination with a toe-calk vwhich is adapted to t into said opening, and which hasa rear extension which lies against the web ofthe shoe and turns up and over said web, as and for the purpose set forth. 2. A horseshoe having a downwardly-projecting flange on its under side, and provided at its heel with a longitudinal lateral slot at the base of the flange and a longitudinal vertical slot in the web of the shoe, in combination with the call; having splines on two of its sides to tit into said slots, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
