IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. 185,363, dated March 13, 1877; application iiled v February 17, 1877.

Improved ThillfCoupling, ofwhich the follow-v ing is a specification:

In the accompanying drawing, Flgure 1 represents a vertical longitudinal section of my improved *chill-coupling, and Fig. 2 a top View of the same.

Similar letters of reference indicate corresponding parts.

This invention has reference to an improved thill-coupling, by which the shafts may be readily shifted from one carriage to another, the saine working, when attached, inan easy and quick manner, and without friction or noise, and without danger of gettin g detached from. the carriage. l

The invention consists of a shaft box or bearing, with hinged topor cap attached by a clip to the axle. The center-pin of the shaft or thill attachment turns in the box, and is retained therein by a locking-lever mechanism, that binds on a tongue of the cap. f

In the drawing, A represents a tixed bearing of my improved thin-coupling, that is secured, in the customary manner, by the clip A', to the axle of the vehicle, the clip A' being bent around the axle and attached to the same by a binding-plate, and by the screw-nuts a at theends otthe clips, in the customary manner. To the outer end `of the fixed bearing A is hinged the top part or cap C, that forms, with the bearing A, the box in which the center-pin B' of the shaft attachment or band B turns. A tongue, b, of the top or cap U, extends toward the clip A', and is locked, after the center-pin B' has been placed into the box A C, by the double lever D D1, oi' which the side links D are pivoted into a recess of the fixed bearing, While the top part or plate D1 is pivoted to the ends of the links D, and provided at the other end with a swinging plate, D2, that tits into the space between the end ot' tongue b and clip A', being seated on `bearing A, so as to rigidly lock the top plate or part D1 over the tongue b, and retain the hinged cap, and thereby the center-pin B', inl position in the box or bearing.

By raising the locking-plate DZ out of its position between tongue and clip, the top' plate and links may be swung back so as to clear the tongue, and admit the opening of the box and the detaching of the shafts in quick and convenient manner.

Having thus described my invention, I claim as new and'desire to secure by Letters Patent- 1. A s an improvement in thin-couplings, the combination ofthe stationary bearing or support A, hinged cap C, and center -pin B' of shaft attachment B, with a lockingv device D Dl D', applied between cap and clip, to rigidly lock the shaft coupling or box, substantially as and for the purpose set forth.

2. The combinationA of the cap C, having tongue b, with the pivoted side links D,'piv oted top plate D1, and swinging locking-plate D2, seated between tongue and clip, substantially as and for the purpose speciied.
