THILL COUPLING.

SPECIFICATION forming part of Letters Patent No. 306,372, dated October 7, 1884.

(No model.)

To all whom it may concern:

Be it known that I, EDMUND Ynrsnn, of Newmanstown, in the county of Lebanon and State of Pennsylvania, have invented certain 5 new and useful Improvements in Thill-Ooup lings; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of refl erence marked thereon, which form part of this specification, in which Figure 1 is a perspective View of my improved combined thill-coupling and clip ap plied to part of an axle. Fig. 2 is a vertical I section through the same, taken in the plane indicated by dotted line a: m. Fig. 3 is a per spective view of the clip and its internallyflanged jaws, the thill being detached. Fig. 4 is a side view of the rear part of the thill,

showing the eccentricity of the eye-piece of the thill-iron.

This invention relates to thill couplings and clips; and it consists in a combined thillcoupling and clip constructed and adapted to operate in a manner which will be fully understood from the following descriptiomwheu taken in connection with the annexed drawlugs.

Before describing my invention I will state 0 that I am aware that it is not new to construct clip-straps with springs for bearing against the eye-pieces of thillirons for the purpose of preventing rattling.

I am also aware that Various devices have been cssayed for preventing thills from dropping in the event of the loss of couplingbolts. Such devices, broadly considered, I do not claim.

A designates a clip adapted to embrace the 0 axle B. This clip is constructed with screwthreaded stems a a, adapted to pass through the clipstrap G, and to receive nuts I), that confine the same to the axle, as shown in the drawings. The clip is also constructed with 4 5 a thickened front portion, iromwhich project two cars, D D, that are parallel to each other. The front portions of the ears D D are perforated laterally to receive a coupling-bolt, E, confined in place by means of a nut, c. On

the inner rounded end of the said ears I form flanges (l (I, which are a little greater than. a

semicircle, thus leaving rear contracted openings, c, for the entrance and removal of the ends of the perforated eyepiece g of the thilliron G. It will be observed that the clip, its screwstems, the ears, and the internal flanges thereof are all constructed entire. The ends of the eye-piece g of the thill-iron G are eccentric, or, in other words, these ends are slightly flattened at f, for the purpose of en tering the recesses formed in the ears D D by the flanges d d, which can only be effected when the thill is in the position indicated in dotted lines, Fig. 2. WVhen the thill is depressed to the normal position indicated in full lines, Fig. 2, it Will be impossible to an couple it from the ears of the clip, for the reason that the greatest diameter of the ends of the eye-piece g is in line with the openings at the back of the flanges cl (1. It will thus be seen that, even should the bolt E drop out of its place, the thill will be prevented from uncoupling from the vehicle. For the purpose of preventing rattling of the thill-coupling when it is somewhat worn, I form on the front end of the clip-strap C a spring, H, which is bent downward, forward, and backward, and thus adapted to press forward against the rear part of the eye-piece of the thill-iron. This spring will press the ends of the said eyepiece against the flanges cl (1 and prevent rattling.

Having described my invention, I claim as new- The combination, with the eye-piece, of the 8 5 thill-iron, the ears of the clip embracing said eyepiece having flanges at their forward edges integral with said ears, the coupling-bolt for securing the eyepiece, and the spring constituting part of the clip-strap,arranged to press 0 against the flattened portion of the eyepiece, the whole being constructed and adapted to be secured to'the axle, substantially as specilied.

In testimony that I claim the foregoing as my 9 5 own I my signature in presence of two witnesses.

EDMUND YEISER.
