'DETACHABLE HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 546,203, dated September 10, 1895.

Application filed January 30, 1895.

To all whom it may concern.-

citizen of the United States, residing at Granville, countyof \Vashington, and State of New York, have invented certain new and useful Improvements in Detachable Horseshoes, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a bottom plan view showing my detachable shoe in place upon the horses hoof. Fig. 2 isa central vertical section of same, taken on the broken line 2 2 in Fig. 1, the position of the hoof being indicated by dotted lines. Fig. 3 is a cross-section taken on the broken line 3 3 in Figs. 1 and Fig. 4 is a longitudinal vertical section taken on the broken line 4 4 in The object of my invention is to-provide a detachable horseshoe adapted to be temporarily applied to the permanently-shod foot of the horse when the condition of the roadway renders the use of the ordinary permanent shoe injurious or dangerous,

A represents a shoe of usual form permanently secured to the hoof of a horse, as by nails A.

Bis the temporary'shoe corresponding in general form with the permanent shoe and detachably secured thereto on the under side. The heel portions of the temporary shoe are enlarged at 15", and the enlarged portions provided each with a socket closed on all sides and at the rear end and adapted to receive a projecting end A of the heel portion of the permanent shoes. The temporary shoe is provided along its inner edge with a plurality of upwardly-projecting lugs B B adapted to engage the inner side of the permanent shoe and prevent a relative lateral movementof theshoe. Asimilarlugortlange B projects upwardly from the forward end or too of the temporary shoe, and by'cngageserial No. 636,658. (No model.)

ment with the permanent shoe on its front side prevents a relative rearward movement of the temporary shoe. A relative forward movement of the temporary shoe is prevented by the engagement of the heels of the perma nent shoe with the end walls of the respect-- ive sockets, aided somewhat by the lugs 13. The two shoes are thus held against relative movement in a horizontal plane by the lugs and socket-walls so long as the parts are held together, so as to prevent a relative vertical movement.

As a means for securing the parts against relative vertical movement, I provide a clip 0, comprising a Hat plate of metal bent into the general form of a staple, having the upper leg 0' shorter than the lower leg 0 \Vhen the two shoes are arranged in their proper relative positions, the clip is applied from the inner side, the shorter leg being driven in between the permanent shoe and the hoof, and the lower leg brought into engagement with the under side of the temporary shoe.

The longer lower leg of the clip is provided with a countersunk aperture registering with a screw-threaded aperture in the temporary shoe, adapted to receive the threaded end of a fastening-screw 0 inserted in the countersunk aperture. The screw maintains the clip in position to resist all strains tending to separate the toes of the two shoes, which are thus held securely together with comparatively little strain on the fastening-screw, permitting the use of a single screw of small size.

The outer or temporary shoe can be detached by removing the screw and clip. The detachable shoe is apertured at B and B to receive the removable cal its D, inserted therethrough and projecting from the lower side of the shoe. The calks are severally secured in the apertures by means of an enlarged head D, adapted to fit a countersink in' the detachable shoe and be held securely therein by the permanent shoe, which overlies and engages therewith, as shown in Fig. 4:. The projecting end of each call; is preferably beveled on two opposite sides to form a wedgeshaped end D the edge of the wedge extending transversely of the shoe. The calks are preferablykeyed in their respective apertures to prevent a rotary movement therein, which would change the line of direction of the beveled edge and diminish the effectiveness of the calk.

I have shown the calks and apertures rect the proper placing of the detachable shoe.

P is a cover-plate which may, when desired, be inserted and secured at its edge between the two shoes, the plate extending entirely across the hoof to protect the same and prevent the formation of cakes of snow and ice in the hollow of the hoof. The plateis apertured to permit the passage therethrough of the lugs B and B and the clip C.

In Fig. 4 the cover-plate is omitted.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a common horse shoe and means for permanently securing the same upon the hoof; of a temporary shoe applied thereto and provided with heel-sockets adapted to receive the respective heel-ends of: the permanent shoe; inner side-lugs and an outer toe-lug on the temporary shoe adapted to engage the permanent shoe; calks supported by the temporary shoe; a clip embracing both shoes at the toe; and a detachable connection between the clip and temporary shoe, substantially as described.

2.- The combination with a common horse shoe, and means for permanently securing the same upon the hoof; of a temporary shoe applied thereto and having countersunk calkapertures, a pair of heel-sockets adapted to receive the respective heel-ends of the permanent shoe, and inner side-lugs, and an outer toe-lug adapted to engage the permanent shoe; calks keyed in the respective coun' tersuuk apertures; a clip embracing both shoes at the toe; and a screw-connection between the clip and temporary shoe, substantially as described.

In testimony whereof I have hereunto set my hand this 18th day of January, 1895.

LEONARD C. THORNE. Witnesses:
