REMOVABLE CALK FOR HORSESHOE S.

SPECIFICATION forming part of Letters Batent No. 710,783, dated Qctober 7, 1902. Application filed February 12,1902. Serial to. 93,717. (No model.)

T0 calf whom, it may concern:

Be it known that I, I-IUBERT A. KENDALL, a citizen of the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Removable Oalks for Horseshoes; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of my invention primarily is to enable calks to be removably attached to a shoe upon the hoof of an animal expeditiously; second, to retain the separate calksupporting plates in contact with the shoe under tension; third, to adapt the plate-securing devices to the width of the shoe.

The invention consists in the novel construction and combination of parts, such as will be first fully described, and specifically pointed out in the claims.

In the drawings, Figure 1 is a plan view of a horseshoe, showing the invention applied thereto. Fig. 2 is a view in elevation of the rear ends of the calk-supporting plates, showing the lips for engaging with the horseshoe and the locking wedge or key. Fig. 3 is a perspective view inverted of one of the calksnpporting plates, showing the lips and also one of the pivotal arms for the forward ends of the plates and the extensions from the rear ends of the plates supporting the expansible plate. Fig. 4c is a detail side view of the pivoted arms for the forward ends of the calk-supporting plates. Fig. 5 is a vertical sectional view of the calk-supporting plate and key, taken upon the line of Fig. 1. Fig. 6 is a detail broken view of the inner side of the rear end of one of the calksupporting plates Similar letters of reference indicate corresponding parts in all thefigures of the drawings.

Referring to the drawings, A represents a horseshoe of the ordinary and well-known description, of which (t represents the forward end or toe and a a the sides and a a the rear ends or heel of the shoe.

The supports for the removable calks comprise separate flat plates B B, each one of which is narrow in width and extends in length nearly that of thelength of the horseshoe or from a position near the tee a. of the shoe to a position a short distance from the rear ends or heels a a of the shoe. The main portion 6, intermediate the ends of the plates B B, is outwardly curved in the same degree as the sides a a of the horseshoe, and the outer ends I) b of said plate are bent outwardly in the direction of the outer edges of the sides of the shoe in curved lines, the width of the plate being designed to cover about one-half of the width of the side of the shoe. From the intermediate portion 6 of the plates .B B the outerends b b are increased in thickness to form ridges or elevations b I), extending to the inner sides of. the calks, the sides of which ridges are inclined at 19 in opposite directions to the outer and inner edges of the to a point and preferably inclined slightly at opposite angles of inclination to each other. Upon the inner edge of the curved portions 1) Z) of the plates B B are lips b I), which are designed to grasp the shoe and extend upwardly a short distance above the plane of the inner surface of the said plates and thence bent forward in a curved line a short distance above and parallel with the said innor surface of the said plate. 011 the inner edges of the forward curved ends I) Z) of the plates B B are the narrow adjusting and bearing plates o I)", which are connected rigidly with said plates B and extend toward each other, one of which is bent upwardly and overlaps the other and both of which extend forwardly in the direction of the toe of the shoe at a slight angle of inclination to each other. In the outer ends of the upper plate I) are separate perforations b If. Upon the upper surface and outer end of the lower plate 1) is a hook 11 which is adapted to enter one of the perforations l) in the upper plate and connect the plates pivotally with each other. Upon the inner edges and at the rear ends of the plates B B are horizontal bearing-plates h which extend a short dis- ICC tance from said plates toward each other. Directly below the inner ends of the plates 0 and in the sides Z) of the ridges b are separate narrow openings b I), the lowermost opening I) being of less depth than the opening 1) and immediately below in position. In the respective openings b b on the plates B B is inserted the ends of an outwardlycurved pliable expansible locking-plate 0, made from soft iron and readily bent into a horizontal position by pressure or from a blow given by a hammer.

In the application of the invention to a horseshoe, the key 0 being removed, the plates B B are drawn together at their rear ends, the forward ends being adjusted to the width of the shoe. The plates B B are then placed in position between the inner edges of the sides of the shoe A and the lips b 19 extended upon the inner surface of the shoe. The rear ends of the plates B B are then spread apart and the ends of the key 0 inserted within the openings 1) b in the said plates. Pressure being applied to the curved plate 0, the said plate is forced upwardly against the short bearing-plates Z) Z1 into a horizontal position, the rear ends of plates B B being simultaneously thrust apart and the lips b 5 caused to grasp the shoe A with considerable force and at the same time effect an adjustment of the plates upon the inner edges of the sides of the shoe. In spreading forcibly the rear ends of the plates B B into position against the inner edges of the sides of the shoe the pivoted plates 1) b", which are at slight angles to each other, causes a resistance to the power applied by the key to secure said rear ends, which resistance or tension is constant during the time the plates B B are upon the shoe.

To remove the plates B B from the shoe, the key 0 is first bent downwardly, and the ends being released from the plates the plates fall from their position.

When the plates B B are attached to a narrow shoe, the key C may be inserted in the upper openings Z2 11 in the said plates, the plates U 1) being detached and the hook b caused to engage with the opening 12 nearest the calk-supporting plate. The utility of the invention not only consists in the expeditious attachment of the calk-supporting plates to the shoe, but in its adaptability to different widths of shoes without additional expense.

Having fully described my invention, what I now claim as new, and desire to secure by Letters Patent, is I l. The combination with a horseshoe, of removablyconnected calk supporting plates, lips upon the inner edges of said plates extending in the direction of the inner surface of the shoe, inwardly-extended plates at the forward ends of said plates, pivotally connected with each other, and an extensible plate at the rear end of said calk-supporting plates.

2. The combination with a horseshoe, of rearwardly-connected calk-supporting plates, lips upon the inner edges of said plates, extending in the direction of the inner sides of the shoe and upon the upper surface thereof, inwardly-extended plates at the forward ends of the calk-supporting plates, pivotally connected with each other, and an extensible plate adapted to engage with the rear ends of said calk-supporting plates and force said plates into engagement with the shoe.

3. The combination with a horseshoe of removablyconnected calk-supporting curved plates, adapted to be secured to the inner edges of the sides of the shoe, inwardly-extended, overlapping plates at the forward ends of said calla-supporting plates inclined at an angle to each other, one of which plates is provided with openings, a hook upon the other plate adapted to engage with the said openings, lips upon the inner edges of the calk-supporting plates extending upon the inner surface of said shoe, said plates having openings upon the inner sides and rear ends, and an extensible plate within said openings.

I-IUBERT A. KENDALL.
