HORSESHOE.

SPECIFICATEON orming part of Letters Patent No. 335,476, dated February 2, 1886. Application filed January 7, 1885. Serial No. l'll. (No model.)

T all wiz/0m it may concern:

Be it known that I, HENRY M. CLIVER, acitizen of the United States, residing at Newark, in tlie county of Essex and State of New Jersey, have invented certain new and useful Improvements in Horseshoes; and I do hereby declarethe following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawiugs, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a horseshoe with removable calks capable of easy adj ustment and securely held in position, and so constructed that the strain is removed from the pin or fastening device which holds the calks in position.

The invention consists in the combination and arrangements of parts substantially as illustrated in the drawings, and described and claimed herein.

Referring to the aecompanying drawings, Figure 1 is a plan of the bottom of a horseshoe having adjustable calks,i1lustrating my invention. Fig. 2 is a perspective view of the toe-calk shown in Fig. 1. Fig. 3 is a transverse section of the toe-calk. Fig. 4 is a front elevat-ion of the toe ofthe shoe and the calk. Fig. 5 is a side elevation of the heel and calk. Fig. 6 is a longitudinal section of Fig. 5. Fig. 7 is a section of the shoe near the heel and an elevation of the heel-calk.

Figs. 8 and 9 are plans of the grooves in the heel and toe,respectively, and Fig. 10 is a perspective view of a toe-calk, showing one form of the same.

In said drawings, a represents the body of the calks, which are wedge-shaped or tapering on the top,and fit in a V-shaped groovein the toe and heel of the shoe, as illustrated in Figs. 3 and 5. From the top or apex of the wedge-shaped part a' of the calk projects a straight arm, b, which is a continuation of one side of the tapering top, as indicated in Figs. 2, 3,&c., and which when adj usted on the shoe enters a socket or perforation, b', in the bottom of the groove in the shoe. The said socket in both the toe and heel grooves extends upward into the body of the shoein a line with one of the inclined sides of the groove and backward, so that the constant tendency of the striking of the shoe upon the ground is to drive the call: more firmlyinto the groove and socket.

A pin, p, is inserted through openings in the sides of the groove and the arm b, as indicated in Fig. 4, or through a tenon formed on the calk, as shown in Figs. 5 and 6. The pin is designed to prevent the calk from falling out, but receives no part of the strain, which is borne entirely by the groove. Additional security is obtained by forming mortises and tenons c on the shoe in the groove and on the side of the calk of which the arm b is a continuatiou, as illustratcd in Figs. 2 and 3.

By forming a groove in the shoe the sides of the groove give great strcngth to the shoe and support the calks on both sidcs. The more strain there is applied to calk the more securely it is held in its place.

I am aware that removable calks have been attached to the shoe by dovetail joints, also that curved and straight perforations have been made in the shoe itself and a circular or cylindrical shank formed on the call; and the shank bent as it is driven into the perforation; but none of the several shoes have a So groove formed 011 the shoe itself, thereby securing great strength, and a socket adapted to receive an arm on the calk, which enters the shoe upward and inclines backward from the bottom of the groove. This construction being formed in accordance with strains to which the calk is subjected when in use, Will be certain to last much longer, and is not liable to becomejamnied so that it cannot be easil y removed. o

Having thus described my invention, I desire to claiin the following:

1. The combination, With a horseshoe provided with a V-shaped groove in the toe and heels thereof, having a straight perforation or socket in the bottom of said groove extending upward and backward into the body of the shoe, of removable heel and toe calks having a wedge-shaped top adapted to fit in said groove in the shoe,and provided with astraight arm which enters the socket in the bottom of the groove, and means, substantially as described, for holding said calk in the groove, for the purposes set forth.

2. The combination, with a horseshoe provided with a V-shaped groove in the toe and heels thereof, having a straight perforation or socket in the bottom of said groove extending upward and backward into the body of the shoe in a line with one of the inclined sides, of the groove, the said side being provided with a mortise therein, of toe and heel ealks having a wedge-shaped top adapted to fit in said grooves in the shoe, and provided `foration in the shoe and the calks, substantially as and for the purposes set forth.

In testimony that I claim the foregoing I 25 I have hereunto set my hand this 16th day of December, 1884.

HENRY M. CLIVER.
