THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 386,276, dated July 17, 1888.

(No model.)

To all whom, it may concern.-

Be it known that I, ANDREW J. SPICER, of Portland, in the county of Multnomah and State of Oregon, have invented a new and Improved Thill-Ooupling, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a transverse section of my improved thill-coupling taken on line 0000 in Fig.

2. Fig. 2 is a plan view. Fig. 3 is an inverted plan view, and Fig. 4 is a detail rear view, of the coupler.

Similar letters of reference indicate cone [5 sponding parts in all the views.

The object of my invention is to rovide a simple, inexpensive, and efficient coupling for quickly and securely connecting thills or poles with carriages.

My invention consists in a clip adapted to clamp the carriage axle and provided with a tapering dovetailed vertical groove, a thillcouplerjointed to the thill-irons and provided with adovetailed arm fitted to the tapering 5 dovetailed groove in the clip, a conicallypointcd screw inserted in the dovetailed arm of the coupler, adapted to engage the clip, and provided with an eye at its outer end and astrap attached to the axle and extending through the eye of the screw, all as hereinafter more fully described.

To the axleAis fitted the clip B, having the threaded shanks a at one edge of the clip, and the clip is secured by an apertnred cross-bar,

5 1), fitting over the shanks a and held in place by nuts 0. The front side of the clip is thickened and provided with a tapering dovetailed groove, (1. To the dovetailed groove d is fitted a dovetailed arm, 6, formed integrally with 0 the coupler G. A screw, D, having the endf pointed, and provided at the opposite end with an eye, 9, is inserted in the threaded aperture in the arm 6, in position to engage the under surface of the thickened front portion 5 of the clip 13. To the axle A is secured a strap,

h, which passes through the eye 9 of the screw D, and is engaged by a buckle, i, secured to,a short strap, j, connected with the axle.

The coupler O is provided with the usual apertured cars, It, for receiving the couplingbolt Z, which passes through the thill-irons m, of the ordinary form. The tapering form of the arm 6 causes it to fit closely in the dovetailed groove (Z by its own gravity, the wider end of the said arm being uppermost. The screw D, passing through the arm a and en gaging the clip Bin the manner described, prevents the accidental escape of the arm 6 from the groove (1, and also prevents rattling. The strap h, inserted in the eye 9 of the screw D, prevents the said screw from being accidentally loosened. To remove the thills from the vehicle, the strap h is withdrawn from the eye 9 and the screw D is loosened, when the arm 6 may be readily lifted from the groove (Z of the clip.

Having thus described myinvention, Iclaim as new and desire to secure by Letters Patent 1. The combination, with the clip B, provided with the tapering dovetailed groove d, of the coupler 0, having the tapering dovetailed arm 0, substantially as described.

2. The combination, with the clip B, having a dovetail groove, (l, the coupler 0, having a dovetail arm, 6, adapted to enter the groove d, of the conically-pointed screw 1), substantially as and for the purpose described.

3. The combination of the clip B, provided with the tapering dovetailed groove (2, the coupler G, having the arm 6, the conically- So pointed screw D, furnished with the eye 9, and the strap h, attached to the axle and extending through the eye 5 of the screw, substan tially as described.

4. The combination, with the clip, B having a tapering dovetail groove, d, of the coupler C, said coupler consisting of the body portion having a tapering dovetail arm, 6, adapted to be fitted in the groove d, and the forwardly-extending arms terminating in aper- 9c tured ears K, substantially as and for the purpose described.
