HORSESHOE.

FFJPECIFICATION forming part of Letters Patent No. 338,139, dated March 16, 1886.

Application filed February 1. 1886. Serial No. 190,504. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES S. CANFIELD,

a citizen of the United States, and a resident of llilinneapolis, in the county of Hennepin and State of Minnesota, haveinvented certain improvements in Removable Galks for Horseshoes, of which the following is a specification.

My inventicn relates to improvements in detachable or adjustable calks for horseshoes, and the objects I have in view are to provide horseshoe-calks that may readily be attached to or removed from any ordinary flat shoe.

It is desirable to remove the calks from a horses shoes when the animal is to stand for any length of time in a stable, as it is considerably easier to stand on the flat shoes. Moreover, horses often cut themselves with the sharp calks on their shoes, either by stepping one foot on another, or in lying down or getting up. It is also necessary, with the ordinary shoes, to remove them once, or sometimes even twice, a week to sharpen the calks.

This process injures the horses feet, besides being expensive. My invention obviates all of these objections.

The invention consists, generally, in the construction and combination hereinafter described, and particularly pointed out in the claims.

In the drawings, forming part of this specification, Figure l is a bottom View of a horseshoe having my invention applied thereto. Fig. 2 is a section on line a: 00, Fig. 1. Fig. 8 is a plan of the securing-bars.

In the drawings, 2 represents an ordinary horseshoe. It may be a shoe without calks, or a shoe whose calks have become worn down so as to be smooth or nearly so, and the shoe may be of any suitable size.

3 represents a metal bar, upon which are formed the heel-calks 5 5. These calks are preferably formed by turning over the ends of the bar.

7 and 9 are curved bars that extend from the toe of the shoe to near the heel thereof, and by which the toe and heel calks are held to the shoe. There is sufficient space between these bars for the frog of the foot when the device is in position.

Upon the forward end of the bar 7 isa flange, 11, that is adapted to be inserted over the top of the shoe, between the shoe and the hoof, without removing the shoe. At its rear end each bar is provided with a laterally-projecting flange, 13 15, adapted to be inserted also between the top of the shoe and the hoof with out removing the shoe. The forward ends of the bars have each a hole that coincide one with the other when the bars are in position. The hole in the under bar is smooth, and that in the upper bar is screw-threaded, as shown in Fig. 2. Each of the bars is also provided at its rear end, opposite the lateral flanges, with a screw-threaded hole.

The toe-calk 17 is formed on a plate, 19, having a hole through it adapted to register with the holes in the forward ends of the bars. This plate is also preferably provided with an upwardly-turned end or flange, 21, that fits over the edge of the bar and prevents turning of the plate on its holdingscrew. A screw, 23, having preferably a square or rectangular head,passes through the toe-call; plate,through the under bar, and is screwed into the threaded.

hole in the upper bar. This screw holds the toe-call; in position and also pivots the two bars together, so that their rear ends may be moved toward each other, or separated to insert or remove their flanges from over the shoe,

' and to adjust the device to shoes of different widths.

The bar 3 is provided near one end with a slot, 25, and near the other with a hole for a screw. Screws 27 extend through the hole and slot in this bar, and are screwed into the holes in the rear ends of the curved bars.

The device is applied as follows: The flange 11 on the bar 7 is first inserted at the toe of the shoe, between the top of the shoe and the hoof. The flange 13 is then similarly inserted near the heel of the shoe. The bar 9 is then put in place, with its flange 15 between the shoe and the hoof, and with the hole in its forward end coinciding with the hole in the end of the other bar. The toe-plate and the, bar 3 are then put in position, and the screws 23 27 are screwed through these parts into the bars, thereby holding the calks securely in place. By removing the screws the calks can be taken off and the bars removed from the shoe, to be again applied when desired.

The calks are made of steel, and the holdin g-bars are preferably east of malleable metal. The calks may be sharpened when desired, and when one set of calks is worn out another can be supplied for the same holding-bars.

The end of the bar 3 having the slot is placed at the outside of the foot, where the end of the bar may project over the outer edge of the shoe without any danger to the horse. The other end of the bar is always within the shoe, so that there is no danger of interfering.

By means of the slotted bar the device may be adjusted to fit shoes of different widths. The calks and securing-bars are made, usually, in three sizes, and maybe applied to any shoes. The bars may be made-of caststeel, if preferred.

I claim as my invention 1. The combinatiomwith the shoe, of the curved securing-bars having the flange 11, and the flanges, 13 15, fitting over the topof the shoe, the plate 19, having the toe-calk, the

bar 3, having the heel-calks, and means for securing said plate and bar to said securingbars, all substantially as described.

2. The combination, with the curved bars 7and 9, having the forward flange, 11, and the lateral flanges, 13 and 15, of the toe-calk plate, the screw 23, securing said plate to the forward ends of said bars, the cross-bar 8, having the heel-ealks 5 5, and the screws 27, securing said bar to the rear ends of 'said bars 7 9, all substantially as described.

3. The combination, with the curved plates pivoted together at their forward ends, provided with the forward flange, 11, and the rear lateral flanges, 13 15, and adapted to fit within the shoe, of the toe-calk, means for securing said calk to the forward ends of said bars, the crossbar 3, having the calks 5 5, and having the slot at one end, and the screws 27, holding said bar to the bars 7 9, and permitting a lateral adjustment thereof, substantially as described, and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 26th day of January, 1886.

A. 0. PAUL, R. H. SANFORD.
