'HORSESHOE SPECIFICATION forming part of Letters Patent N o. 599,712, dated March 1, 1898..

Application filed April 16, 1897.

To all whom t may concern:

Be it known that I, WILLIAM R. KINNEAR, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Horseshoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Theobjectof my invention is to provide a shoe of simple and economicall form adapted to receive calks that may, when` worn, vbe easily and quickly replaced by new ones, thereby obviating the now common expense of frequently shoeing the horse.

My invention consists, flrst,of the improved construction of the shoe, and, secondly, in the improved form of calk hereinafter described and claimed. Y

I have illustrated my improvements in the annexed drawings, in which- Figure lV is a plan view of the under side of the shoe with one of the heel-calks removed. Fig. 2 is a sectional view takenon the linesm of Fig. l. Fig. Sis avertical central sectional view of a modified form of calk. Fig. 4 is'a side view of another modification, and Fig. 5 is a side elevation of an instrument that may be employed to remove and insert the calks.

.In the several views like characters of reference designate corresponding parts.

l designates the shoe proper, the bodyl of which is generally fiat ,and thin and made with screw-threaded bosses or projections 2.

for the reception of calks 3. The screwthreaded bosses may be of any number; but two at the toe and one at each of the parts of the heel, as shown, will ordinarily suflice.` I make the calk hollow, in the form of a short tube, with the edge of its treadingy part 32L rather sharp, so as vthe better to take into the road or ice upon the road, and withV a threaded shank 3b to enter the threaded boss 2 on the shoe proper. Formed upon the under side of the shoeproper and lying parallel to the sides of the shoe, between the toe and i heel bosses, are two ribs or beads 4 and 5, the

inner rib 4 being of about the same altitude as the bosses, and the outer rib 5 being of less height, as shown. The nail-holes 6 are made in the shoe between these ribs 4 and 5, as indicated.

' cavity of the calk.

Serial Nol 632,480. (No model.)

If desired, the calk may be made with a shoulder 7, as indicated in Fig. 3, at the base of the threaded part, so that when the calk isturned into the shoe said shoulder may be in firm contact with the end of the boss and so relieve the strain on the thread, but when the thread is made large this Will not be necessary. The inner wall of the calk is made with a square or other non-circular opening or socket 30, located below the outer edge or Ytread portion of the calk, to receive a ttingkey by which the calk may be turned into or out of the shoe. In placing the socket 3C below the tread portion of the calk the socket is protected against wear and disfiguration. Such a key is shown in Fig. 5, where the end 8 is indicated as made so as to it a square hole or socket. The other end of the instrument may be pointed, as shown at 9, and therefore conveniently used to pick out a stone or dirt that may happen to lodgeinrthe The socket 3C is also made to extend beyond or above the tread-face of the shoe when in position, so that should the calk be worn entirely down or even with the shoe a part of the socket will still remain to b e engaged by the wrench.

In Fig. 4 I have illustrated a hollow calk according to my invention, having a portion of its tread removed or omitted, so thatin its contact with icy pavements the ice shall be penetrated, but not entirely broken, and therefore a firmer and surer hold of the shoe upon the pavement afforded.

The ribs 4 and 5, betweenthe calks, strengthen the shoe, and by making theinner bead or rib of greater altitude than the outer one the nails are more easily driven into place and their heads protected.

With the shoe herein described the shoe proper is nailed to the' hoof to remain an indefinite period, and the calks are renewed as -fas't as they are worn down. To renew the calks does not require the skill of a profes- IOO which are below or beyond the outer edge or tread portion of the calk, and extend beyond or above the tread-face of the shoe when in position, whereby said polygonal socket is I5 protected against injury from contact with the pavement, substantially as shown and described.
