TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN AUSTIN, of Rockford, in the county of Winnebago, and State of Illinois, have invented certain new and useful improvements in Horse-Shoes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters `ot reference marked thereon, like letters indicating like parts wherever they occur. p

To enable others skilled in the art to construct yand use the'invention, I will proceed to describe tf.

Figure 1 is abottom plan view. i i

Figure 2, a 'side elevation; and

Figure 3, a vertical section, taken on the line a: a: of g. 2.

My invention consists in the insertion in the calks of a piece of steel set vertically, to render the calks self-sharpening. It further consists Ain a novel construction of bolt andshoe, for the purpose of securing it to the fbot without the use of nails, and without the necessity of going to a blacksmith. i

A represents the shoe, which is made of a single piece, in the usual form. This shoe is secured to the horses foot by means of bolts C, which are inserted through inclined holes bored in the hoof at the proper positions to correspond with holes made in the shoe; the position of the bolts being clearly shown in section in g. 3. These bolts' are provided with heads, which stand at an inclination to correspond with the side of the hoof, when the bolt is inserted, as shown in fig. v3. The lower ends-of the bolts pass through the shoe, and are secured by nuts o. In order to'protect the nuts and the ends of the bolts a guard, B, is formed on the under side of the shoe, around that portion through which the holes are made, the under face of the shoe being made concave within the guard B, as shown in section in figs. 3 and 4. In order Vto avoid'the necessity of injuring` the hoof by boring new holes, in case a shoe is used in which the holes do not exactly correspond with .the

holes of the hoof, I make an elongated hole or slot in the shoe, as shownv at n, iig. 1; and in this slot are fitted a number of small pieces, e, space being left for the passage ofthe bolt C. These pieces e have a. bevelled head, tting into a corresponding recess n tho upper side of the shoe, which prevents them from falling out. These piecese can be shoved either forward or backward inthe slot n, and thus-throw the opening for the passage of the bolt either forward or backward, as maybe desired. A Avertical slot is cut, or otherwise made, in the calks of the shoe; and in this slot`is secured a thin piece of steel, as shown by a. This steel, being much harder than the iron of the calk, will, ofcourse, wear away more slowly, and hence will protrude below the iron, thus forming a self-sharpening calk, and one that will remain so as long as the steellasts.

To attach the shoe, it is only necessary to bore the hol'es, insert the bdlt C, apply the shoe, and screw on the nuts. By these means I save all danger of injuring the animals foot by nails, make a less number of holes in the hoof, and provide a shoe that can be applied without the aid of a blacksmith, and in which the ealks are renderedself-sharpening.

vHaving thus described my invention, what I claim, is-

1. Securing the shoe to the animals foot by means of the bolts C, constructed and applied as shown and described.

2. ,Thermovable pieces e, secured in the slot n, substantially as and for the purpose set forth.'

3. I claim. making the ealks self-sharpening, by inserting within the body ofthe calk a. piece of steel, substantially as described.

JGHN AUSTIN.
