THlLL-COUPLING C'LANI P.

SPECIFICATION forming part of Letters Patent No. 241,251, dated May 10, 1881.

(No model.)

To alt lwhom t may concern Be it known that I, BARTLETT N. TORREY, of the United States, residing at Creston, in the county ot' Union and State ot' Iowa, have invented certain new and useful Improvements in Thill and Tongue Coupling Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to theaccoinpanying drawings, and to letters or figures of reference marked thereon, which forni a part of this specification, in which- Figure l is a perspective showing` my iinproved clamp. Fig. 2 is a vertical sectional elevation, showing my improvement applied in coupling a thill to an axle. Fig. 3 is a sectional elevation, showing its application in coupling a tongue or draft-pole.

This invention relates to a thill and tongue coupling clamp, or clamp for compressing elastic anti-rattler blocks in thill and tongue couplings 5 and the invention consists in constructions and combinations of parts hereinafter dcscribed, and set forth in the claims hereto annexed.

Referring to the drawings byletters, the saine letter indicating the same part in the different figures, letter A represents a section of a carriage-axle; B, a clip; U, jaws j'iroiecting from the clip, D, rear end of a thill, E, thill-iron with eye c on its end, and F rubber-block placed between the eye c and clip B. The thilliron E is curved upward and forward from the eye c. The foregoing parts are shown by full lines and constitute parts of an ordinary vehicle, which may be constructed in any usual manner.

Gr represents my improved clamp, having jaws gg on one end, which are preferably curved so that they may clasp pretty closely around the rear end ot' the thill D or iron E. The jaws g are journaled to each other at Vg', and have their rear ends extended to form jaws gf. Separating the jaws g will canse the jaws g to approach each other, and vice versa.

H H are jaws projecting laterally, one from each jaw g, and are located near the pivoted end ot' the jaws g, and preferably curved -inwardly or toward each other at their outer ends.

I also prefer to have them curved or inclined toward the jaws g at their outerends.

At Fig. 3 an ordinary tongue or draft pole iron J, with coupling-eyej, is shown, which projects straight or nearly straight from the axle, and does not curve upwardly as does the thilliron E.

K is a lever, tapering or wr-nlgeshaped at one end.

W'hen used in coupling thills, as shown at Fig. 2,the clamp is placed over the axleA, with the jaws g embracing the thill D, or the iron E, or both, according to the extension of the thill-iron beyond the end of the thill. The wed ge-shaped end of the lever K is then passed downward between the jaws g, and, forcing them apart, will force the jawsg toward each other, so as to hold the thill securely. The lower end ofthe lever rests against the axle, and its upper end may be drawn backward to draw the eye c against the elastic block F, and coinpress it so that the ordinary coupling-bolt in ay be inserted. The jaws g may be adjusted on the thill, and a lever used without a wedgeshaped end, it' preferred. A piece of leather or other soft material may be attached to the lever where it rests against the axle, or simply placed between said parts.

Then used in coupling tongues or draft-poles without raising the forward end ot' the tongue, the clamp is placed `on the axle with its jaws H pointing downward, so that they may embrace the coupling-iron J. The lever K may then be used in the same manner as hereinbefore described, to force the iron J backward and compress the rubber so that coupling may be efected. By means of the jaws EI the clamp is made to draw the tongue-iron J backward and not upward.

I do not limit my claims to the exact construction ot' the clamp as shown 5 but That I claim as new, and desire to secure by Letters Patent, is-

l. A coupling-clamp having hinged jaws adapted to embrace the thill or tongue, with their rear ends extended to form other jaws which receive and hold a lever, by which force may be applied to compress the elastic block between the thill or tongue iron and axle, sub. stantially as shown and described.

2. A coupling-clamp having hinged jaws g- IOC or H, adapted to embrace the thill or tongue, with their rear ends extended to form other jaws, gg, in combination with a wedge-shaped lever, which m ay be used to tighten the hold of the jaws g or H on the thill or tongue, while at the same time used to force the thill or tongue backward and compress the elastic coupling-block, substantially as and for the purpose specied.

3. A coupling-clamp having jaws g g, with other jaws, H H, projecting laterally therefrom, and with their rear ends extended to form other jaws, g g", by means of which both sets of first-named jaws may be operated, substanb tially as and for the purpose specified.

el. In combination with u coupling-clamphaving hinged jaws g H y, a lever which may be inserted between the jaws g and used to compress the elastic rubber in thlll or tongue couplings, substantially as and for the purpose speei- 2o BARTLETT N. TORREY.
