TOOL FOR APPLYING AND REMOVING HORSESHOE GUARD-PLATES.

SPECIFICATION forming part of Letters Patent No. 440,099, dated November 4, 1890.

Application filed March 19, 1890- Serial No. 344,455. (No model.)

To all whom it may concern.-

Be itknown that I, GEORGE T. CHAPMAN, a citizen of the United States, and a resident of IVhite Plains, in the county of VVestchester and State of New York, have invented new and useful Improvements in Tools for Applying and Removing Horseshoe Guard-Plates, of which the following is a specification.

My invention consists of an improved tool for springing and shortening guard-plates for horseshoes, which are secured in the shoe by the thrusts of the ends of the plates when sprung against the walls of rabbet-grooves of the shoe between which the plates are applied, all as hereinafter fully described, reference being made to the accompanying drawings, in which Figure 1 is a plan view of a horseshoe and a guard-plate applied to it, such as my improved tool is provided for. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is a side elevation of my improved tool for applying and removing the plate with a plate connected and sprung as for being applied to a shoe. Fig. 4 is an elevation of said tool in a plane at right angles to that of Fig. 3.

The shoe is made with a bar a, connecting the heels 1), and integral therewith and in the lower inner corner of the bar and in the corresponding part of the toe c rabbets cl are made transversely to the shoe as long as the requisite strength and bearing-surface will permit and parallel to each other, together wit-h the short extensions of the same at d (dotted, Fig. 1) along the sides of the shoe, between which rabbets d the guard-plate e is inserted, said guard-plate consisting of a stiif plate of steel or other elastic metal, made slightly longer than the distance between the verticalwalls of the rabbets, and being sprung so as to shorten it for so inserting it, and so as to retain its place after being inserted by the thrusts of the ends against said vertical walls through the power of its resilient force. It is in this instance represented with attached calks 0 but they may be used or not. The plate is thus secured without any detachable fastenings, which is important in horseshoes. The arrangement of the rabbets in the toe and heel connecting bar is especially advantageous, because they are protected from being spread apart as when located in the side bars of the shoe without the heel-oonnecting bar. For springing these plates I provide a powerful clamp, consisting of the base-plate f, having feet 9 to rest on the surface of the guard-plate at its extremities, the T-headed coupling-rod h fitted loosely through the center hole 11 of said plate, (dotted,) with its head j insertible through the slot is in the middle of the guard-plate, and the levers Z, pivoted at m in the upper end of the coupling-rod, with the lower ends adapted to thrust down on the base-plate and cause the head of the coupling to thrust upon the guard-plate iutermediately to the thrusts of the feet on the upper side by forcing the levers so as to close the short arms toward each other in the manner of a pair of tongs, said levers being preferably provided with anti-friction rollers 07. to facilitate closing them.

To insert the head of the coupling-rod in the guard-plate, the base-plateis placed on the guard-plate, and the levers Z are opened to allow the rodto drop freely in the baseplate, and they are turned to a vertical plane at right angles to that in which they are used after being inserted, as seen in Fig. 4, which places the T-head lengthwise with the slot of the guard-plate, when it can be passed through the slot. Then the levers are turned back to the position represented in Fig. 3,-

which places the head crosswise with the slot, so as to engage the plate properly for thrusting in opposition to the thrust of the feet of the base-plate when the levers are closed.

It will be understood that the tool is alike applicable for springing like plates for any purpose. The levers are gaged so that they spring the plate to the required extent when the handles meet, beyond which point they cannot well be moved, and thus the spring ing of the plate too much, which would be injurious, is prevented.

I claim as my invention- The combination of the base-plate having the feet at its extremities and the hole through the center, the T-headed coupling-rod inserted in the hole and movable therein, and the levers pivoted to the coupling-rod and 2 MQQQQ having the short arms rid-fluted to thrust On ence of twowitnesses, this 13th day Of March, the base-plate when the -head is engaged 1890. below and the levers are forced so as to swing the short arms toward the coupling-rod, sub- CHAPMAN 5 stantially as described.

In testimony that I claim the foregoing as WILFRED B. EARLL, my invention I have signed my name, in press- W. J. MORGAN.
