HORSE SHOE Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed January 26. 1907. serial No. 354,235.

To all whom it may concern:

Be it known that I, DANIEL BARKER, of North Bay, in the district of Nipissing, Province of Ontario, Ganada, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification.

My invention relates 'to horseshoes; and its objects are to provide a shoe, capable of adjusting itself to the foot and giving a natural freedom of movement thereto, thus preventing hoof contraction, inflammation, and other diseases produced by tight shoes, which will yield itself readily to alteration for different hoofs and will afford a firm support for the hoof to which it is attached.

The invention consists essentially of two side members which are pivoted to a front plate, as the front calk, for oscillatory movement thereon, said side members having outcurved engaging ends.

The invention consists further in a shoe of this character, in which the curvature of the ends is less than that of circles struck around the pivots as centers. In a shoe constructed in this manner the outcurved ends may easily be altered, as by filing, to permit greater or less range of movement according to individual requirements: further, the shoe combines the advantages of both the pivoted-section and rigid types of shoe, since the curvature of the engaging ends of the sections permits a limited range of movement, but does not afford absolute flexibility, thus giving a firm but not rigid support to the hoof.

Figure l is a perspective view of the shoe. Fig. 2 is a vertical section through the calk. Fig. 3 is a sectional view on the line 22, Fig. 2. Fig. 4 is a perspective view of the calk prior to the assembling of the shoe together.

In the drawings like letters of reference indicate corresponding parts in each figure.

A and B are the two side members of the shoe of the usual curved form abutting at their center.

0 is the front calk which may be made of any desired shape, but has the top :1 thereof enlarged, and provided with upwardly protruding pins b and c, which extend through counter-sunk holes d and e in the members A and B and thus pivotally hold the same in position. The ends f and g of the members A and B are slightly outcurved as shown, whereby a limited oscillatory movement of each member will be permitted, the two members A and B rolling on each other. It will be seen that the curvature of the engaging ends of the sections is less than that of circles struck around the pivot pins as centers, whereby the two sections may rock upon each other to a certain eX- tent, but are not permitted entire freedom of oscillation. Thus, proper support for the hoof is insured.

In assembling the shoe together the calk is first formed with the two pins 1) and c, which will be slightly longer than the thickness of the members A and B. The pins are then inserted through the holes d and c in the members A and B, and by means of a few blows from a hammer, the tops of the pins b and c are spread to fill the counter-sunk portions of the'holes d and c. This holds the side members firmly in position, but enables them to adjust themselves to the natural movement of the horses feet.

It is to be observed that a shoe constructed after the principles of my invention, namely with outcurved engaging ends, may be readily adjusted during assembling according to the requirements of different hoofs. This is accomplished by filing the engaging ends of the sections, prior to riveting, in order to render them more or less rounded, thus permitting greater or less freedom of movement. This feature is of particular advantage in permitting adjustment for hoofs of horses of different ages, it being a recognized fact thathoofs of young horses have a greater tendency to spread at each step than do the hoofs of older horses.

It will be readily understood that while I have described with great particularity of detail one specific embodiment of my invention; yet in carrying out the same, considerable changes may be made in the details of construction within the scope of the appended claims without departingfrom the spirit of my invention.

What I claim as my invention is:-

1. A horseshoe, comprising a front plate, side members having their forward ends outcurved and abutting to alford a rolling contact, and a pivot pin connecting each member to the plate.

2. A horseshoe, comprising a front plate, side members abutting at their forward ends, and pivot pins connecting said members to the plate, the abutting ends of said members having an outward curvature less than that of circles struck about the pivot pins as centers.

Signed at North Bay, in the Province of Ontario, Canada, this 19th day of January, 1907.

DANIEL BARKER.
