SPECIFICATION forming part of' Letters Patent No. 279,223, dated June 12, 1883. Application filed J anuany 15, 1883. (No model.)

To aZZ whom it may concern:

Be itknown that I, OREN M. CHASE, of Detroit, in the county of \Vayne and State of Michigan, have invented new and useful Imshoes, by means of which the same, when in use, are kept sharp, so far as it relates to their calks, until worn out. I

The invention consists, primarily, in the peculiar construction of the calks, and, secondarily, in their combination with a horseshoe, as more fully hereinafter described.

Figure 1 is a perspective view of my improved horseshoe and calks reversed. Fig. 2 is a perspective of one of the calks removed.

In the accompanying drawings, which form a part of this specification, A represents a horseshoe, preferably made of cast-steel and unprovided with calks; but it is provided near each fork of the heel with a threaded hole to receive the threaded shank of the calk, and the same provision is made at the toe for securing the toe-calks. The calks B are also preferably made of cast-steel, stelliform or cruciform in shape, the wings a rising from a bed-plate, b, with which such wings are integral, and with which bed-plate is provided with a shank, c, which is threaded to engage with the threaded holes in the shoe. One of these calks is de-- signed to be attached, as shown, to each fork of the heel,while two of the calks will be found preferable at the toe, standing side by side, with a sufficient distance between them to allow of their being turned.

If the condition of the screw-threads is such as not to secure-the calk in proper position, if

y it was a calk of the ordinary shape it would stand lengthwise of the shoe, whereby it would not perform its function, and the object of 5 giving the peculiar form to the calks shown and described is to prevent this difficulty, as no matter in what position the calks stand with relation to the shoe to which they are secured, one pair of wings will at all times furnish the necessary resistance to the slipping of the horse when traveling.

I am aware that it is not new to adjustably secure calks to horseshoes by means of screws upon such calks engaging with threaded holes in the shoe. Hence I do not broadly claim such method of securing calks to horseshoes.

I am aware that a calk having a screwthreaded shank on one side and cutting-flanges on the other, constructed with inclined sides,

is shown by English Patent No. 845 of 1876, and do not desire to claim such a calk, but limit myself to the peculiar construction shown and hereinafter claimed.

Vhat I claim as my invention is-' 1. A calk for ahorseshoe, consisting of a flat bed-plate, I), having on one side projecting flanges a, constructed with vertical sides cross-.

ing each other at right angles and a screwthreaded shank, 0, on its other side, substantially as described.

2. The combination, with a horseshoe, A, of one or more calks, B, consisting of a fiat bed-plate, b, having on one side projecting flanges a, constructed with vertical sides cross ing each other at right angles, as shown and described, and a screw-threaded shank, c, on theother side, inserted into a like shaped and threaded recess in the shoe, as set forth.

OREN M. CHASE.
