Leim Patent No. 90,224, dated May 1s, 1869.

IMPROVEMENT IN DETACHABLE CA'LKS FOR HQRSESHOES.

The Schedule referred'to in these Letters Patent and making part of the same.

To whom lit 'ma/y concern:

Beit known that I, WILLIAM JONES Bamm, of Gincinnati, Hamilton county, Ohio, have invented a new and useful Detachable Calk for Horseshoes; and I hereby declare the following to be a full, clear, and exact descr'iption thereof, reference being had to the accompanying drawings, making apart of this specification.

This invention relates to a compact and strong, yet light calk for ready attachment to, or removalrfrom a horseshoe, while the'latter is on the hoof of the animal.

Figure 1 represents the parts of my calk detached, viewed from above.

` Figure 2 is a longitudinal section through the parts in position.

Figure 3 represents a modification of my improvement, viewed from below.

A, figs. 1 and 2, represents an ordinary horseshoe without toe.

B and O aretwo jaws, of malleable iron, adapted to 'trate the hoof; a dovetailed shank, E, which enters a correspondingly undercut gain or groove, F, in the jaw C; va nut, G, for the reception of a screw, H, which screw, passing through the jaw O, serves to draw and hold the two jaws together, and to cause them to tightly grasp the horseshoe.

The jaw B has also an' undercut groove, I, on its under side, to receive and hold a steel bit, J, which constitutes thehtoe proper.

In addition to the parts named, the jaw C has a lip, K, which, overlapping theinner edge of the shoe, serves, in conj unctiou with the spurred ange D D' and the screw H, to hold the calk firmly to the shoe, and to prevent it dropping oii` of the latter when in use.

An excavation, c, iu the jaw C, permits the uut G to enter said jaw as the parts are screwed home.

In orderto protect the hoof, and to cause auniform bearing against it of thejaw B, and to prevent rattling, a cushion, L, of India rubber o1l leather, may be interposcted between the flange D D' and the front of the hoo Fig. 3 represents a modification of my invention, adapting it for use in shoes having a customary fixed toe-calk.

In this form of my invention the ange D D bifurcates downward as well as upward, so as to avoid the xed toe-calk, and each branch has a separate dovetailed groove and bit, as shown in said figure.

I am aware that a somewhat similar device has been patented by Edward Sneider, under date of October 2 1866.

One difference existing between Snieders inventi n, and my own is the exactly opposite manner in wh h the two work.

While his is fastened to the -shoe by the pressure of one end of the screw-bolt against the rear edge of the shoe, my improvement is secured by the direct action of the same upon the detachable calk itself, the latter being drawn back by the screw, so as to take rm hold of the hoof, as heretofore described.

My invention is also an improvement upon Sneiders inasmuch as in mine the supplemental shoe described by him is dispensed with, as are also the split-spring washer and the studs on the rear extremity of the supplemental shoe deseribedin his patent, and rendered necessary, the former by the manner in whichth bolt acts upon the shoe, the latter to prevent latera displacement.

In my improved detachable calk these cumbersome attachments are all rendered unnecessary by the pe`- culiar construction of the parts B and C.

I also construct my improvement so that it may be applied to the common shoe, having the ordinary toecalks in front.

.My improvement 1s also supplied with a movable toe-piece proper J, which may be inserted or taken out at pleasure, by means of its wedge-form and the dovetailed groove I.

I do not claim the broad principle of attaching movable ealks to horseshoes; but

' What I do claim as new, and of my own invention, and for which I desire to secure Letters Patent, is-

1. The detachable calk, composed of the jaw B, spurred auge D D', dovetailed shank'E, nut G, nndercut groove I, steel bit J, jaw O c, gain F, lip K, and screw H, constructed and combined to operate slibstantially as and' for the purposes set forth.

2. In combination with the detachable calk, the pad L, for the purposes specified.

In testimony of which invention, I hereunto set my Witnesses:

Gao. H. KNIGHT, JAMES H. LAYMAN.
