THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 371,428, dated @ctoloer 11, 1887.

Application filed June 30, 1857.

Serial X0. 243,054 (No model.)

zen of the United States, residing at Spring field, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Thin-Couplings; and I do 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 same.

My invention relates to improvements in thill-couplings; and it consists in the novel construction and arrangement of devices,1:s hereinafter specified and claimed.

In the accompanying drawings, Figure 1 is a longitudinal vertical sectional view of a thillcoupling constructed accordingtornyimprovements. of the same on line mm, Fig. 1. Fig. 3 is a View ofthe double-armed lever removed, and Fig. I is a crossscction taken on the lines y 3 of Fig. 3.

The letter A of the drawings represents a clip attached to the axle-tree in the usual mauner by nuts and screws. This clip is constructed wit-h a bifurcated front extension, (marked 13,) which is adapted to receive therear end of a thill and hold it securely by means of a pin or bolt, 0, as shown in Fig. 1 of the drawings, the bolt requiring no thread or nut.

The letter D represents a casting,the upper end of the rear wall of which is curved rearwardly, as shown at a, and adapted to clasp the eccentricshaped and double-armed lever, hereinafter described, and the bottom portion of said casting constitutes a rectangular recess for holding a rubber block, also hereinafter mentioned.

The letter E represents a lever provided with two arms, as shown in Fig. 3. The central portion of this lever, which is clasped by the curved extension of the casting D, is made round in cross section, while its ends between said round portion and handles are camshaped, as shown in Figs. 2 and3 ot' the drawlugs.

The letter H represents a block of rubber which rests in the rectangular recess formed in casting D, and is constructed with a concave upper face,which,when on duty, rests against Fig. 2 is a transverse sectional view the lower side of the thill, as shown in Fig. 1. I usually provide a plate. (marked 0,) which is interposed between the bottom of the recess in casting D and the rubber block H.

Theletterg represents a thumb-screw, which is passed through the bottom of the casting D, in a. threaded opening, with its point resting against the bottom of plate 0, the point being riveted into a countersink to prevent the thumb screw from coming out.

My invention is operated as follows, namely: After the several parts have been placed in position the arms of the cam-levcr E are turned downwardly, each arm of which fits closely over the ends of the pin or bolt G and holds the same securely. The thumbscrew g is then turned until the desired pressure is obtained against the lower side of the thill,and the work is completed.

It is obvious that by this construction the cam-shaped lever will hold its arms securely over the ends of the pin or bolt 0, and by means of the thumb-screw g the rubber block can be given such a pressure against the thill that all rattling and noise will be avoided. or bolt 0, being held in position by the cam lever E, (which can be raised or lowered by loosening the thumb screw,) does away with the necessity of anut on the bolt, enabling the operator to. uncouple the thill with case and rapidity.

I claim as my invention 1. In a thill-coupling, the combination,'with the clip having the perforated lugs, of the angular casting adapted to receive the rubber, the thill-bolt, and the cam-bolt having the levers or arms adapted to embrace the ends of the thill-bolt, substantially as specified.

2. The combination, in a thill coupling, of

I the casting adapted to receive the rubber block,

and the cam-boltforminga fulcrum for the said casting and having lateral arms adapted to prevent the displacement of the thill-bolt, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
