THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 374,634, dated December 13, 1887.

Application tiled May 23, 1,887. Serial No. 289,688. (No model.)

To all whom it may concern:

Be it known that I, PETER ENoon Samir, of Blue Ball, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Thin-Couplings, of which the following is a specification. v

The aim of my invention is to provide an adjustable device applicable to thill-couplings such as are now in general use Without change or alteration therein to prevent the rattling of the thills.

Referring to the accompanying drawings, Figure l represents a side elevation of a clip having my device applied thereto. Fig. 2 is a top plan view of the same. Fig. 3 is a section on the line fr x of Fig. 2. Fig. 4 is a perspective view showing the parts of my attachment separated from each other and from the coupling.

Referring to the drawings, A represents the thill-iron mounted at its rear end on the trans.

verse bolt B, which is seated at its ends in the forwardly-projecting arm's a of the clip O, which latter is mounted on the axle D and secured at its lower end by the clipplate E vand nuts b.

it against and around the thill-iron between.

the arms of the supporting-clip, and, second, of a metallic plate, d, adapted to t against the rear side of the rubber block, with an arm to engage over its top, and also with a depending arm or stem, d', which is carried downward and forward through a plate or washer, e, and connected at the lower end by a horizontal pivot, f, to a cam-lever, g, the lower end of which is preferably provided with a strap-opening, as shown.

In making use of the device the bolt is removed and the thill removed from its clip, the device inserted between the arms of the clip, and the thill inserted and secured by the bolt, as shown in Figs. 2 and 3. Vhen the this form of clip resting in the concave face of the rubber holds the same in position, and the rubber in turn holds the plate d. The cam-lever is next turned forward from its original position (shown by dotted lines in Fig. 3) to the position shown by full lines in the same figure, the effect of which is to vforce the washer e upward and turn the plate d downward, thereby subjecting the rubber toa vertical compression and crowding it tightly around and against the end of the thill, the effect being, as the rubber and plate are supported by the bearing of the latter against the face of the clip O, to hold the thill ironsnugly to its place and render its action entirely noiseless. A strap, G, passed from the thill through the end of the cam-lever, will serve the double purpose of preventing the leverfrom being accidentally thrown out of position and of retaining the thill in the event of the bolt or other part giving away.

I am aware that various devices have been contrived for securing and confining rubber andv other elastic material against a thill-iron,

vand this I do not broadly claim; but I believe myself to be the first to provide a cushion and compressing device such as herein described, adapted for application to thill clips or couplings of ordinary form.

My device is highly advantageous in that it may be quickly applied to or removed from existing couplings without the employmentot' special tools or instruments for the purpose, and that when the rubber is released from compression t-he latter' ceases its pressure upon the thill-iron, allowing the bolts to be readily withdrawn without mutilating or injuring its thread.

' Having thus described my invention, what I claim is- 1. 'Ihe anti-rattling attachment for a thillcoupling, consisting of the recessed elastic block, the plate adapted to engage over and behind the same, and providend with an eX- tended end, the washer encircling said end and bearing against the cushion, and the eocentric lever applied to said end outside of the washer.

2. In combination with a thill iron and clip of ordinary form, as represented, the anti-rat` tling attachment consisting 0f the recessed this 18th day 0f May, 1887, in the presence of rubber block seated over and around the thilltwo attesting witnesses.

- iron the metal plate beauin0F between the face of the clip and the rear facebof the block and PETER ENOGH SHIRK' 5 engaging over the latter, the underlying XVitnesses:

washer, and the eccentric lever. D. S. SCHLAUOH,
