JOHN N. NAVIN, OF INDIANAPOLIS, INDIANA.

HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 234,71*?, dated November 23, 1880.

Application led July 12, 1880. (No model.)

To all whom it may concern Beit known that I, JOHN N. NAVIN, of Indianapolis, Indiana, have invented a new and useful Improvement in Horseshoes, of which the following is a specification. The objects of my invention are, first, to provide a shoe for horses which can be so fastened to the foot as to allow free play to the natural elasticity of the walls of the hoof, and thus prevent disease of the foot; second, to a'ord a means of curing or relieving the disease known as contracted hoof77 by spreading the walls of the hoof after the shoe has been placed in position and retaining them in the desired position 5 third, to provide a convenient means for securing pads or other appliances in contact with the frog or under side of the foot. I attain these object-s by the use of the shoe illustrated in the accompanying drawings, in which- Figures l and 2 are plans; Fig. 3, a side elevation, and Fig. 4 a rear elevation.

Similar letters referto similar parts throughout the several views.

a isa shoe, of the usual form, in the upper side of which is formed a dovetailed recess, b, into which is nicely tted a separate removable piece, c, thus completing the contour of an ordinary shoe. The removable piece c is provided with nail-holes, as is also the other side of the shoe, in the usual manner.

(l d are upward-projecting lugs, formed upon or welded to the upper surface of the shoe at the heel, and designed to fill loosely the space between the walls of the hoof when the shoe is rst secured to the foot. A portion ofthe shoe is cut away at the toe on the inner edge, at e, for the purpose ot' making the shoe weaker at that point, so that when force is applied between the lugs d d. to spread that portion of the shoe apart it will bend at that point, c, and not at .any intermediate point, the object of this being to prevent any cramping or binding of the removable piece c in its recess, and also to secure an equable and proper spreading of the hoof in a case ot' diseased hoof, as hereinafter explained.

For the purpose of securing to the under side of the foot rubber pads or other appliances used in the treatment of diseased feet, the lugs d d are provided with holes f. By passing a small rod or wire through these lugs and the pad or other appliance before the shoe is secured to the foot the pad when applied is securely held in place. v

My improved shoe is applied and operates in the following manner: The shoe being tted to the foot in the usual manner, the position of the removable piece c is marked upon the hoof. It is then removed from its recess and nailed to the foot in its proper position. The shoe is then slipped upon the piece c, the dovetailed forni of which retains that side of the shoe in place, and the other side is then nailed in the usual manner.

When the horse rests upon the foot or strikes a violent blow, as in running, the piece c slides in its dovetailed recess, and allows the natural elasticity ot' the walls ot' the hoot' to operate, thus preventing disease.

lt' the foot is already in a diseased conditionfrom wearing a stift', unyielding shoe, and has become contracted, I now apply a suitable lever between the lugs d d and spread the shoe, thus bending it at e and spreading,` it permanently, mostly at the heel, diminishing gradually to the toe, and holding the Walls oi' the hoof apart. This being done with care and good judgment leaves the softer portions of the foot free to regain their normal condition and relieves the disease.

I claim as my inventionl. A horseshoe provided with the removable dovetailed piece c, fitting in the recess b, and adapted to be separately secured to the foot and to retain the shoe against the foot, at the same time allowing a sliding motion thereon, as and for the purpose set forth.

2. A horseshoe consisting oi' the principal portion a, removable piece c, and provided with the lugs d d and weakened portion c, substantially as set forth.
