TOE-CALK FOR HORSESHOES.

SPECIFICATION formingpart of Letters Patent No. 553,345, dated January 21,1896.

Application filed May 23, 1895. fierial No. 550,309. (No model.)

To all whom it may concern:

Be it known that I, WViLLIAM J. KENT, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Toe-Calks for Horseshoes, of which the following is a specification.

This invention relates to horseshoes, and is applicable either to those known as ordinary or road shoes or to those known as racing shoes or plates.

The invention relates particularly to shoes having a wearing or gripping face or edge at the outer part of the bottom face, a longitudinal groove at rear of said face or edge, having an upwardly and rearwardly inclined wall extending from said edge upwardly into the body of the shoe, and a rearwardly-extending top for said groove above and at rear of said gripping-edge, one example of a shoe of this character being shown in my application for Letters Patent, filed April 27, 1895, Serial No. 547,300 and the invention aims to provide an improved toe-calk, especially applicable for attachment to such shoe.

To this end in carrying out the preferred form of my invention I provide a toe-calk consisting of a single metallic piece adapted to be applied to the bottom face of a shoe, having a downwardly-projecting part constituting a working portion, a longitudinal rearwardly-extending hearing or shoulder at top of said part adapted to bear on the bottom face or gripping-edge of the shoe, an upwardly and rearwardly inclined wall above said shoulder, adapted to embrace a corresponding wall on the shoe and be attached thereto, and a longitudinal bearing at the upper edge of said wall adapted to bear on an upperportion of said shoe, said shoulder and bearing serving to support the shoe from the calk,

and said wall to connect the calk to the shoe, and I provide said calk with a rear side extending from said upper bearing downwardly to said working portion, and preferably forwardly to the front part thereof, so that the latter consists of a narrow working or gripping edge for the calk.

In the accompanying drawings, which illustrate the preferred form of the invention. Figure 1 is a bottom face view of a shoe and toe-ealk embodying my improvements. Fig.

2 is a side elevation thereof. Fig. 3 is a crossseetion thereof on the line 3 3 in Fig. 1. Fig. 4 is a rear elevation of the calk alone. Fig. 5 is a cross-sectional view thereof; Fig. 6 is a front elevation thereof, and Fig. 7 is a diagrammatic View showing how the calk strikes the ground.

Referring to the drawings, let A indicate the shoe, and B the toe-calk. The shoe A has an elongated body of any suitable construction and material, having on its bottom face an outer hearing or gripping edge or portion 0,

immediately at rear thereof an upwardly and tom face H extending from said second edge G to the inner side I of the body. From its inner side I the body has a flat outwardly-extending top face J, and at its outer side an outer downwardly and usually rearwardly inclined front wall K. The edge or bearing 0, inclined wall D, and face E are preferably continuous parts extending throughout substantially the length of the shoe, and substantially parallel relatively each to the other in their extension. The space between the walls D and F constitutes an upwardly-extending groove in the bottom face of the shoe.

The calk B according to my invention consists of a metallic piece having a lower or working portion (it below the shoe, an upper or fastening portion b for attachment to the shoe, a bearing or shoulder c at its front side between said portions bearing 011 the gripping or wearing edge or face of the shoe, an upwardly and rearwardly inclined face (Z above said bearing adapted to fit a corresponding face D on the body of the shoe, a rearwardly extendin g bearing or edge 6 above said face adapted to fit a corresponding portion, as the portion E of the shoe, and a rear wall f extending from said hearing or edge e downwardly and forwardly to said working portion. The bearing or shoulder cis adapted to support the calk 011 the wearing or gripping faee or edge 0 of the shoe, by hearing thereon or being attached thereto. The rearwardly-inclined face (Z is curved longitudi- IOC nally and proportioned vertically to substantially fit the upwardly and rearwardly inclined face D of the shoe, and adapted to be attached thereto, and serves to retain the toe calk in connection with the shoe. The upper bearing or edge e is shaped to fit the part E of the shoe and bear thereagainst, thereby in part supporting the calk on the upper and inner portion of the body of the shoe near the middle thereof. When the partE of the shoe is terminated by a downwardly-extending wall F the edge e of the calk may be extended rearwardly into contact with this wall, as shown, thereby assisting in preventing displacement of the calk relatively to the shoe. The rear wall f of the calk extends downwardly and forwardly to the working portion of the latter. By preference this wall is a substantially straight wall extending from the upper part of the calk to the forward part of the lower part or bearing, or wearing, portion thereof, and the calk is constructed with a downwardly-extending, and preferably substantially vertical front wall g extending from the front bearing or shoulder 0 downwardly and meeting the rear wall f at a point or edge h, serving as the wearing-edge of the calk, and sufficiently narrow or sharp to serve as a gripping-edge therefor. The walls 9 and f diverge upwardly from the edge h, thus giving the calk a triangular cross-section for its wearing portion, which is thickest at the point where the shoulder c is located. From this point the portion Z) of the calk extends diagonally'rearw-ardly and upwardly in the form of a thin wing or flange, of uniform or slightly-tapering cross-section, depending on whether the walls (1 and f are parallel or slightly diverging, as shown.

In operation, the calk having been suitably attached to the shoeas, for example, by brazing its face cl to the face D of the shoe, with its bearing-shoulder 0 bearing on the bottom face or edge 0 of the latter, and its bearingedge ebearing in the top of the groove formed by the walls D, E, and Fthe calk will support the shoe at two points, the one at its front lower outer edge 0 and the other at its upper middle portion E, its fastening to the shoe will be mainly intermediate of these points and at the points of engagement of the face d and wall D, and the wearing portion of the calk will project downwardly, either substantially vertically or slightly inclined, as desired. In striking the ground the strains will be transmitted through the calk to the two parts of the shoe to which its bearings are applied, and the tendency to backward displacement of the calk will be resisted by the rearwardly-inclined portion 1) of the latter, the inclination of which and of the rear wall f and the affixing-face (Z will be substantially in the direction of thrust as the calk strikes the ground when the horse is running.

The calk is preferably constructed of a single piece of solid metal, rolled or otherwise formed of the described or desired cross-section, elongated longitudinally to give it the desired breadth, and curved to conform to the curvature of the shoe to which it is to be applied.

It will be seen that my invention provides improvements in toe-calks for horseshoes which can be easily availed of and successfully used, and it will be understood that the invention is not confined to the exact details of construction and arrangement set forth and shown as constituting its preferred form, since it may be adopted according to such modifications as circumstances or the judgment of those skilled in the art may dictate without departing from the spirit of the in vention.
