HORSESHOE-CALK ATTACHMENT.

SPECIFICATION formingpart of Letters'Patent No. 245,1 6, dated August 2, 1881. Application filed January 31,1881. Modem To all whom it may concern Be it known tlIat'L'JOSEPH O. HIGGINS, of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a new .tachable calks for horseshoes, which calks can be attached to or detached from the shoe without removing the shoe from the horses hoof.

The invention consists in a horseshoe-calk attached to one end of a plate provided with a pivot fitting into an aperture in the undersurface of the shoe, which plate has a recessed flange fitting against the inner edge of the shoe at its other'end, this recessed flange being held against the inner edge of the shoe by a wire passing through a transverse groovein the upper surface of the shoe. -When this wire is cut the plate can be rotated so that the recessed flange leaves the edge ofthe shoe, thus permitting the calk and plate to be removed. In the accompanying drawings, Figure 1 is a plan view of the under side of the shoe, showing the calks in various positions. Fig. 2 is a cross-sectional elevation of the shoe on the. lines a: 00, Fig. 1. Fig. 3 is a perspective view of the toe-calk, showing it removed from the: shoe. Fig. 4 is a detail view of the wires.

Similar letters of reference indicate corre-.

sponding parts.

The toe-call: A is attached to one end of a; metal plate, B, having on its upper surface a. pivot, 0, fitting into a corresponding aperture in the under side of the horseshoe D. This plate B has a recessed flange, E, extending in opposite directionto the calk A at its other end, the width of the recess F of the flange E being equal to the thickness of the shoe D, whereas the depth of the recess must be sufficient to form a short lip, G, at the upper edge of the flange E. When the calk is fastened to the shoe D the flange E rests against the inner edge of the shoe, the lip G resting on the upper surface of the shoe, as shown in Fig. 2. A transverse groove, H, passes across the upper surface of the shoe and strikes the edge of the flange E, which is provided with a notch, J, of the same cross-section as this groove H. A groove, K, extends downward over the outer edge of the shoe and forms a continuation of the groove H. A wire, L, having one end bent, as shown at M, passes through the groove H, the bent part M resting in the groove K,

and the inner end ofthis wire is then bent over the outer surface of the grooved flange E, as shown at N.

The rear calks, A A are attached to similar plates, 13 and B, with recessed flanges E and E and are held in the same manner by wires L and L".

The operation is as follows: If a calk-for instance, A"is to be attached to the shoe, the pivot O is passed into the corresponding aperture, the inner edge of the flange E passing along the inner edge of the horseshoe. Then the plateis rotated in the direction of the arrow a so that the lip G will pass over the upper surface of the shoe D and the inner surface or edge of the shoe D will pass into the recess of the flange E. The wire L is then passed through the groove H, and the inner end of the wire is-bent over the flange E, and thus holds the flange against the inner edge of the shoe; but as long as the flange is held in this position the plate B cannot be rotated in the ;reverse direction of the arrow a, and the call:

is held to the shoe. To remove the calk, the wire L is cut by means of a cold-chisel and then drawn out, so. as to permit the plate to swing outward and be removed.

The calks can be attached or detached very conveniently without taking the shoe from the horses hoot, for the wires L can always be passed through the groove H very easily.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A detachable calk for horseshoes, made substantially as herein shown and described, and consisting of a call: attached to a plate provided with a pivot fitting into a corresponding aperture in the shoe and with a recessed flange resting against the inner edge of the shoe, as set forth.

2. The horseshoe D, constructed with a transverse groove, H, in its upper surface and a groove, K, in its outer edge, in combination with the call: A, attached to a plate, B, having a pivot, O, and a recessed flange, E, and with the wire L fitting into the grooves H and K and bent over the flange E, substantially as herein shown and described, and for the purpose set forth.
