THILL-COUPLlNG.

S'PECIPIGATIN forming part of Letters Patent No. 387,414, dated August 7, 1888.

Application filed May 28, 1888. Serial No. 275,282.

To all whom it may concern.:

Be it known that I, WILLIAM H. HAsKELL, a citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain Improvements in Thill-Couplings, of

which the following is a specification.

My invention consists of certain improvements in the thill-coupling forming the subject of previous Letters Patent Nos. 185,528,

1o 205,082, and 279,381, one object of my present invention being to simplify and cheapen the construction of the coupling, and a further object being to render it easier of operation than those before patented. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a section of the coupling in its operative position. Fig. 2 is a similar view 2o showing the parts adj usted to permit the detaching of the thill from the coupling, and Figs. 3 to 7 are detached perspective views of the various parts composing the coupling.

A represents part of the axle, to which the g5 usual clip, a, is secured by means of a transverse bar, b, and nuts d, the clip having in front of the axle opposite projecting ears f, between which its the eye g of the thill-iron B, the opposite ears having openings for the 3o reception of the pivot-pin D of the thill.

Fitting between the ears f of the clip is a frictionblock, F, which has lugs i, bearing upon the tops of the ears, and is provided with a springarm, G, the lower end of which engages with a grooved collar, h, secured to or forming part of a screw-stem, I, the latter being adapted to a nut, m, which is swiveled to the lower end of a frame, J, comprising opposite plates n, connected by a transverse 4o bar, p, these plates having a bearing upon the axle at m, and being hooked at their upper ends for adaptation to the grooved end portions of the pivot-bolt D of the thill, these end portions projecting beyond the opposite ears fof the clip when the bolt is applied to the thill-eye.

When the upper hooked ends of the plates n are in engagement with the recessed ends of (No model.)

the pivot-pin, and said plates have their bearing upon the axle, the position of the nut m 5o may be said to be fixed, and by turning the screw-stem I the lower end of the spring-arm G may be drawn outward, so as to draw the friction-block F firmly against the thill-eye,

1and thus prevent rattling of the same. When 55 it is desired to detach the thill, however, the screw-stem I is so manipulated as to draw forward the nut m and the lower ends of the plates n, the bearings of said plates upon the axle forming a fulcrnm, and thus causing the 6o upper hooked ends of the plates to be lifted free from engagement with the projecting recessed ends of the pivot-pin D of the thill, as shown in Fig. 2, so that said pin may be withdrawn laterally and the thill removed, a reversal of the direction of movement of the screw-stem serving to again lock the parts in position on the reinsertion of the thill and its pivot-pin.

While my present coupling has all the ad- 7o vantages of the previous coupling as regards the use of the ordinary clip with its ears and the ordinary thill-iron, the present coupling is simpler and cheaper in construction and more readily operated than those before patented.

The pivot-pin D is independent of the plates f, sothat the thill can be detached without necessitating lateral movement of said plates, the only manipulation necessary in Order to 8o confine or release the thill being the turning of the screw-stem I.

The friction-block F is recessed in the center, so as to bear only upon the end portions of the thill-eye, and thus laterally confine the same, as in the coupling shown in Patent No. 205,082.

Having thus described my invention', what I claim, and desire to secure by Letters Patent, 1s 9o 1. The combination of the clip and its ears, the thill-iron and its pivot-pin, the frictionblock having a projecting arm, the lockingplates engaging with the pivot-pin and having a bearing on the axle, and a screw-stem and nut for acting on the plates and on the arm.
