EMIL LILIENTEAL, or NEw YORK, N. Y.

IMPRovEMENT IN BRIDLE-BiTs.

Specification forming part of Letters Patent No. 178,013, dated May 30, 1876; application led March 13, 1876.

To all whom it may concern:

Be it known that I, EMIL LLLIENTHAL, of the city, county, and State of New York, have invented certain new and useful Improvements in Bits 5 and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification.

Manyeorts have been made to ameliorate the condition of horses, and prevent injury from the harness usually employed upon them.

The object of my invention, which also has these ends in view, is to produce a bit with the cheek-pieces so fastened tothe mouthpiece that heat or cold from the latter shall not be transmitted by conduction to the former and cause injury and pain by such trailsmission, as is 110W the case; and it consists in the means hereinafter fully described and claimed.

In the drawings, Figure 1 shows a harnessbit containing my invention. Figs. 2,3, and 4 show modifications of the same.

Between the cheek-piece A and the mouthpiece B I interpose any material which is a non or poor conductor of heat and coldksuch as leather, prepared wood, paper, felt, cork, rubber, hard or soft Celluloid, dto., the lirst five materials being preferably made stiff and water-proof in any well-known manner. One Inode of interposing such material consists of a washer, C, made from suchmaterial of any desired form, placed between a shoulder, a, on the end of the mouth-piece and the cheekpiece A, and a polygonal bush, D, also made from such material, fitting snugly in a correspondingly-formed aperture in the cheek-piece A. The polygonal end e of the mouth-piece passes through correspondingly-shaped apertures in the washer and bush, and is firmly 1 secured to the cheek-piece by means of a metal nut, F, embedded in a hard-rubber disk, G, the nut being of lesser diameter than the bush, and thus not coming in contact with the cheek-piece, as is shown in Fig. 1.

Another mode consists in securing a piece of non or poor conducting material, H, in the A covering, c, of cement or other poor or non conducting material, may be placed over the end of the piece H and bolt I, if desired; or the two may be flush with the outer face of the cheek-piece, as is also shown in Fig. l.

In Fig. 2 I have shown the mouth-piece B made entirely of hard rubber, or other non or poor conducting material or composition, one

end being screwed into the cheek-piece at K,

vand the other caused to enter an aperture corresponding to that in which the piece H fits in Fig. 1, the rubber being then softened by heat, and a wedge, L, driven in to expand 'it to ll the recess.

In Figs. 3 and 4 I have shown another form of aperture, the .cheek-piece being countersunk on both sides, and grooved to per-V mit-the end of the hard-rubber mouth-piece to enter when heated, and be prevented from turning when expanded therein.

I do not confine myself to Vthe exact forms "of joints just described, as any, whether rigid or adjustable, in which the cheek-piece is separated from the mouth-piece by poor or non conducting material will come within the scope of my invention.

By themeans described heat and cold are ei'ectually prevented from being conveyed by conduction to the mouth-piece, and the consequent injury to the horse arising from theV old form of bit, wherein this conduction takes place, is prevented.

Having described my invention and the merits it possesses, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the cheek-piece and mouth-piecewithanon orpoorcondueting mzt- In testimony whereof I have signed myA terial placed between the two, substantially name to this specification in the presence of as described. two subscribing witnesses;
