THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 443,021, dated December 16, 1890. Application iled April 2l, 1890. Serial No. 348,756. (No model.)

To a/ZZ whom t may concern:

Be it known that I, THOMAS A. VATROUS, a citizen of the United States, residing at Elmira, in the county of Ohemung and State of New York, have invented a new and useful Thill-Coupling, of which the following is a specification.

My invention relates to improvements in thill-couplings of that general class in which a rubber cushion or anti-rattler is employed and secured in place bya cap which fits over the ends of the coupling-pin to hold the same in its position.

The especial object ofmy invention is to provide means by which the cap and the antirattler can be quickly and easily secured in place upon completed vehicles provided for the ordinary thill-eouplings; and it consists in i certain novel features hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of my improved thill-coupling. Fig. 2 is a longitudinal section. Fig. 3 is a detail perspective view of the locking plate ornut. Fig. dis ahorizontal section on the line fr, Fig. l. Fig. 5 is a transverse section.

Referring to the drawings particularly by letter,A designates the bearing-arms of the usual construction. The thill-iron B is pivoted between the bearing-arms A by a pin C, and a cap D is fitted over the bearing-arms and the end of the pin in the manner shown in Letters Patent No. 413,379, granted to me October 22, 1889. The rubber cushion or anti-rattler G is arranged in rear of the thilliron and bears thereon, and below the antirattlcr and the arms A, I arrange the locking plate or nut Il in position to engage the screw I after it has passed through the cap and anti-rattler. The locking plate or nut is pref` erably formed of brass, so as to prevent rusting, and is provided at its rear with lips or flanges J, which engage the under edge of the shackle and prevent the locking-plate being drawn upward between the bearing-arms, and the said flanges also engage the stem of said shackle-clip, so as to prevent it from rotating when the securing-screw is turned.

I n practice t-he several parts are iitted together, as shown and described, and the se curingserew is turned so as to move downward through the antirattler and engage the locking-plate, thereby drawing the cap down firmly on the bearing-arms and compressing 5 5 the cushion, so that it will exert considerable pressure on the eye of the thill-irnn. The locking nut or plate forms a bearing for the screw, so that the desired operation of the device is insured. The front edge ofthe lock- 6o ing-plate is beveled and grooved, as shown in Fig. 3, whereby it is adapted to fit and partly underlap the thill-iron.

My improved device is extremely cheap and simple and can be easily and quickly ap- 6; plied to the thills of completed vehicles without disturbing the fixed parts, marring the paint, or requiring the services of a skilled person.

The several parts are readily detachable, 7c so that they can be easily removed when broken or worn and new part-s applied. The cap-plate is preferably made a little crowning (see Fig. 4) instead of fiat, as shown in my patent before referred to, the crowning form being better adapted to leave sufficient space for a rubbercushion of the size and form best calculated to be an effective anti-rattler. rlhe edge of the cap is cut away in front, as seen at CZ, Fig. l, to favor the rubber and ren- 8o der it more lasting by allowing` it to move with the thill-iron when in action.

Having described my invention, what I claim, and desire to secure by Letters Patent, 8 is- 5 l. The combination, with the axle, the clip having bearing-arms, the thill-iron, and the coupling-pin pivotally connecting the thilliron to the couplingarms, of the crowningcap resting on the bearing-arms and fitting 9o over the ends of the pin, the cushion below the cap and in rear of the thill-iron, the locking-plate below the cushion and independent of the clip-plate, and the securing-screw passing through the cap, the cushion, and the locking-plate, substantially as specified.

2. The combination, with the bearing-arms, the thill-iron, and the coupling-pin inserted through the thill-irons and bearing-arms, of the cap resting on the bearing-arms and fitroo ting over the ends of the coupling-pin, the cushion below the cap and in rear of the tliilliron, theloeiiingpiate having beveled grooved my own I lhave hereto affixed my si glm'tu re in edge adapted to underiap and it the thiiLron presence of two witnesses. :md provided with horizontal lips engaging the stem of the clip, and the securing-screw THOS. A. \VA'I`R()US. 5 inserted through the cap andthe cushion and Witnesses;

engaging the looking-plate, as set forth. J. E. VARNUM,
