SPECIFICATION forming part 0f Letters Patent N O. 478,435, dated July 5, 1892.

Application iiled January 2'7, 1892. Serial No. 419,425. (No model.)

To all whom it may concern/.-

Be it known that l, JOHN EDMUND J ARvIs, veterinary surgeon, of 39 Victoria Road, Kensington, London, in the county of Middlesex, England, have invented new and useful Improvements in Horseshoes, of which the following is a full, clear, and exact description.

My invention relates to a combined metal and rubber horseshoe in which the india-rubber is combined with the metal shoe in such a way that the weight shall be principally borne by the Wall of the hoof and the indiarubber shall be held in place by the metal shoe and its fastenings and shall constitute an integral part of the wearing-surface of the shoe, the sole of the hoof being either uncovered or so far covered as to bring a part of the weight onto the frog, as may be desired.

The principal advantages of my invention arelightness, elasticity of tread, the prevention of slipping, the protection of the heels and feet from undue pressure, the prevention of cutting and clicking, and the avoidance of capped elbows.

`Reference is to be had to the accompanying drawings, forming part of this specification, wherein- Figures l, 2, and 3 represent a side elevation, under side plan, and cross-section on line of one form of compound shoe in which the sole of the foot is covered.

My compound shoe is formed partly of iron orsteel and partly of india-rubber and leather, the metal being situated at the parts exposed to the roughest wear.

The part a resembles an ordinary iron or steel shoe, except that it is considerably narrower and lighter and does not extend to the heel of the foot, but stops short at the point a.

b is a horseshoe-shaped cushion of rubber of greater thickness and length than the metal part a. The cushion b is cemented upon a hoof-shaped leather sole-piece or backing d. The lower outer edge of the cushion b is cut away or rabbeted to form a groove, which receives the metal part snugly within it, and also to form a thin flange d of rubber to be interposed between the metal part ot and the sole-piece-or backing d, as shown in Figs. The width of the rabbet is about the same as the metal portion and the depth of the rabbet is greater than the thickness of the metalportion a, so that the lower or wearing face of the cushion will be in a lower plane than that of the metal portion a. in the cushion b does not extend as far as the extremities b of the cushion, and the heels b2 are thus the width of the cushion including its ange. The rear ends a of the metal part a abut against the end walls of the rabbet or groove, which end Walls are formed by the forward ends of the heels b2.

The leather backing CZ may be cut away, if desired, so as to leave the sole of the foot entirely uncovered. The formation of capped elbows by metal heels when the animal is lying down is prevented by terminating the metal part at the points a and having the heels of rubber, as at b2.

The rubber cushion b receives the shock, as its lower face is exposed throughout the entire extent of the metal part, and its thin flange d lies between the leather backing d and the metal portion a. The nails are to be driven through the usual nail-holes in the metal section ct of the shoeand will pass also through the rubber flange d and the leather backing d, thus securing the several parts of the shoe firmly to the animals foot.

Having now particularly described and ascertained the nature ofthe said invention and in what manner the same is to be performed, I declare that what I claim isl. A composite horseshoe formed of a leather sole-piece or backing, a rubber horseshoeshaped cushion on the lower face thereof and having its lower outer edge cut away or rabbeted in front of its heel portion b2, thus forming the outwardly-projecting flange d', and the metal portion ct, fitting snugly Within said rabbet or groove and having its heels a resting against the rear end walls thereof and its up` per face engaging said flange, substantially as described.

2. In a horseshoe, the sole-piece orbacking d, having a horseshoe-shapedrubber cushion b on its lower side formed with heel portions and rabbeted around its lower outer edge in front of said heel and forming the outward projecting flange d', substantially as described.

3. A composite horseshoe consisting of the The rabbet L TOO sole piece or backing the horseshoe-shaped rubber cushion b on the lower `face thereof, having heel portions b2 and rabbeted or out away on its lower outer edge in front thereof, thus forming an outwardly-projecting iiange d', and the metal portion resting on the flange d in said rabbet Withits rear ends a' resting against the forward end ofthe heel portion b2, the depth of the rabbet being greater than the thickness of the metal portion a, causing the Working face of the cushion to lie in a lower plane than that of the metal portion a, substantially as described.

The foregoing specification of my improvements in horseshoes signed by me this 4th l5 day of January, 1892.

JOHN EDMUND JARVIS.
