WM5/KM* TTENEZYI Patented June 3, 1930 UNITED STATES ARTHUR SMITHSON, OF MINNEAPOLIS, MINNESOTA NAILLESS HORSESHOE Application filed December 7, '1928.

This invention relates to a nailless horseshoe; and the main object is to provide a simple, efficient shoe of said kind embodying particular improvements with reference to a horseshoe Patent No. 1,451,007 issued April 10, 1923, in the United States Patent Office to George M. Bogie and myself jointly, the new features herein being invented by myself only.

In the accompanying drawing:

Fig. 1 is a top view of a horseshoe embodying my improvements,

Fig. 2 is a longitudinal sectional elevation of the shoe as on line 22 in Fig. 1, and

Fig. 3 is a bottom view of the shoe with some of its fastening means omitted.

Referring to the drawing by reference numerals, 5 designates a horseshoe of about the usual conventional shape but preferably closed by an integral cross member 5C at the rear or heel part and said cross member having its upper surface flush with the top of the main shoe. If the closed type of shoe is not desired it may be open at the rear and terminate as at lines 5L The main or U-shaped part of the shoe is formed as a continuous downwardly opening channel of inverted U-shape in cross-section, the lower edges of the flanges thereof being formed with a number of teeth 5T normally in a common plane with said flanges. 6 is a tread of resilient material such as rubber and formed to be frictionally retained in the channel, said member 6 projecting below the shoe and preferably rounded as shown. This tread is further retained by bending or hammering the teeth 5T inwardly to retain the outer edge parts (see Fig. 3).

The tread 6 is shaped to terminate as at lines 5L for the open type of shoe, or may be molded with a cross-piece 6H on which the heel part 5C rests, or may be retained in any suitable manner. It is obvious that the downwardly rounded face of the tread is the ground-engaging part normally yielding when the weight of the horse is on it but also normally supporting the metal parts of the shoe from 'contact with the ground. Thus is provided a non-skid shoe particularly use- Serial No. 324,485.

ful on slippery, icy, or hard surfaced roads or driveways.

8 are detachable fingers,removably fixed to the shoe at various points, each of L-shape, and comprising an upright portion 8A and a horizontal tapered plate 8P terminating in a threaded part 8T to receive a special nut 9. The shoe proper is provided withV corresponding inwardly tapering apertures so that the threaded parts` 8T project into the opening of the shoe. 10 is a spring washer about the threaded part and arranged to be pressed against the inner face of the shoe by the nut 9, the latter being elongated as shown to cover the threads of the bolt part and prevent accumulation of ice, dirt, or any foreign matter injurious to the threads. Above the shoe proper each finger part 8A is serrated inwardly at its perimeter, the serrations being downwardly and inwardly directed teeth at the sides and preferably even teeth at the top, designated respectively as 11 and 11A, all said teeth adapted to engage the side of the hoof; and 12 are a number of integral prongs, also directed inwardly for the same purpose, and located intermediate the serrated edges.

I also provide further shoe-holding means comprising what may most aptly be termed sole-locks, each comprising a radial upwardly extending tapered and elongated prong 13 presenting an upwardly directed knifelike edge formed integral of the shoe and adjacent its outer edge.

These sole-locks need extend inwardly only a short distance, and it is clear that in applying the shoe to a hoof these locks are pressed into the latter without injury thereto.

In Figs. 2 and 3, 111 are pairs of horizontally registering apertures in the inner and outer flanges of the shoe, provided in suitable numbers, each pair of apertures adapted to receive a nail 15 driven inwardly and through the tread to hold said tread solid. The nails should be long enoughto go through the inner aperture and be clinched as at 15C.

The use and application of my improved horseshoe will be readily understood. The shoe, without the fingers 8, is first put in place on the hoof and given a few taps to cause the sole-locks 13 to be imbedded. Then the fingers 8 are inserted at their respective places, preferably one in front and one at 5 each side, and drawn tight against the hoof by means of the nuts 9. Until the tread 6 is considerably worn no metal will touch the ground, and saidA worn treads may be readily replaced by simply bending the 10 prongs out and withdrawing the nails l5.
