THlLL-COUPLING.

QPECIPICATION forming part of Letters Patent No. 325,864, dated September 8, 1885.

Application filed May 12, 1885.

To all whom it may concern:

Be it known that I, ABIJAH L. ROMANS, of Sinclairville, county of Chautauqua, New York, have invented a new and Improved Thill-Goupling, of which'the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved device for coupling thills securely to axles and preventing rattling.

The invention consists in the combination, with an axle-clip, of a spring held on the same and of a latch pivoted to the clip and-acted upon by the said spring, which latch prevents withdrawing the bolt.

The invention also consists in the combination, with the said spring, of an additional spring acting on it, all as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved thillcoupling and the pliers for opening it. Fig. 2 is a plan view of the thillcoupling. Fig. 3 is a sectional plan view of the bottom plate. Fig. 4 is a side view of the latch.

The axle-clip A, ofthe usual constru ction,has the two jaws B, between which the thill-eye O is passed, and which jaws have apertures for receiving the couplingbolt D, having a head, D, on one end.

Directly below the axle J a flat metal bar, E, is held by the ends of the shanks of the clip, and is provided at its rear with two upwardlyprojectingjaws, F, in which a pin, F, is held.

Below the bar or plate E a spring-ban'G, is held by the ends of the clip A, and has a bend at the rear end, the end of the said bend being between the jaws F.

A spring-bar, H, is provided at one end with a loop, H, through which a pin, F, passes, and from the said loop it is bent downward to form a lip, I, which rests upon the free end of (ModeL) forked piece, L, is pivoted, which is provided with a lug, M, resting against the free front end of the spring H.

The forked piece L also has a screw-stem, N, which is passed through a longitudinal slot, 0', in a latch, 0, held on the pieceLby a nut, P.

Thelatch O is provided at its top with a cup, Q, in which a recessed rubber cushion, R, is held by a bolt, S, and nut.

The operation is as follows: The rubber cushion R rests on the head of the bolt D, and thus prevents withdrawing the said bolt. The front end of the spring H rests on the lug M, and this prevents swinging down the latch 0 from the end of the bolt D. The front end of the spring H, resting against the thill-eye, prevents rattling of the coupling. The free rear end of the spring G, acting on the lip I of the spring H, presses the said lip upward, and thereby presses the front end of the spring H against the thill-eye and on the lug M.

To uncouple, the pliers W are used in the manner shown in Fig. 1, the end of one jaw being placed against the loop H and the other jaw against the spring H, and, pressing the handles of the pliers together, the free end of the spring H is pressed from the thill-eye and raised up from between the jaws B, which pern'iits of swinging down the latch O, the lug M swinging upward, so as to permit withdrawing the bolt D.

The rubber cushion B also prevents rattling.

Having thus described my invention,I claim as new and desire to secure'by Letters Patent 1. The combination, with an axle-clip having jaws for holding a thill-coupling bolt, ofa spring secured tosaid clip and having one end rested against one end of a spring extending over the axle, and having its other end rested against the thill-eye, substantially as herein shown and described.

2. The combination, with an axle-clip, of the plate E, havingjaws F, the spring H, held on the said jaws, and projecting over the axle and resting against the thill-eye, and the spring G, held on the bottom of the clip and having its free end rested against the spring H, substantially as herein shown and described.

3. The combination, with an axle-clip, of the plate E, having the jaws F, the pin F, held on the same, the spring H, having the loop H,

and the lip I, the front end of the spring H resting against the thill-eye, and the spring G, held by the clip and having its free rear end rested against the lip I, substantially as herein shown and described.

4. The combination, with an axle-clip having jaws between which the thilteye is pivoted, of a spring resting against the thill-eye, and of a latch pivoted to a plate held by the clip, the latch resting against the end of the coupling-bolt, and of a lug projecting from the latch and resting against the end of the spring resting against the thill-eye, substantially as herein shown and described.

5. The combination, with the axle-clip A, having the jaws B, of the spring H, resting against the thill-eye, the pivoted forked piece L, having the lug M, and the latch 0, held on the forked piece L, and having the cushion R, substantially as herein shown and described.

6. The combination, with the axle-clip A, having the jaws B, of the spring G, the plate E, havingjaws F, and the spring H, having the latch I, acted on by the spring G, substantially as herein shown and described.

7. The combination, with the. axleclip A, having jaws B, of the plate E, having jaws F, the spring G, the spring H, on which the spring G acts, the pivoted forked piece L, having the lug M, and the latch O, secured to the forked piece, substantially as herein shown and described.
