THILL COUPLING.
(No Model.)
Patented Jan. 31,1882.
INVENTOR WITNESSES J.
ATTORNEY UNITE STATES 'FFICE.
ATENT THILL-COUPLING.
SPECIFICATION forming part of Letters Patent No. 253,066, dated January 31,1882.
(No model.)
To all whom it may concern:
Be it known that I, HENRY F. KING, a citizen of the United States, residing-at Buffalo, in the county of Erie and State of New York, have made certain Improvements in Thill- Couplings, of which the following is a specification.
This invention relates toa double clip around the axle, and also to improvements in the tightening'spring to better prevent rattling, all as hereinafter fully explained.
In the drawings, Figure 1 is a side elevation of the device, the wooden axlein section; Fig. 2, a front view, showing the double clips, 810.; Fig. 3, bottom view of spring and base.
A A represent the ordinary wooden and iron axle and inclosed by two shackles or clips, B B, and between which the round rear end, 6, of the thill O is fastened, as shown in Fig. 2. These clips also hold a curved C-spring, D, which rounds from the bottom and back of the axle, over the top and front thereof. It is attached to or forms part of a flat cross-piece, a, which, with the spring D, sets against the under side of the axle, and has two outside cross-pieces, b b, also forming part of the piece a and-spring D, through which the ends B B of the clips go, with nuts 0 c thereon. These nutsc c prevent any loosening and allow ot' a continual tightening up if the clips become at all loose, while the bottom piece, a, ofthe spring D, of which it forms a part, with the side pieces, I) I), keep the spring from any side play.
Two shackles or clips are employed instead of one, as is customary, as for heavy wagons especially the thill will be held better and more firmly, and the bolt (7, that goes through the thill-eye, with a solid head on one end and a screw-nut on the other, can be tightened by the nut as often as wear occurs without taking the clip off, as has to he done with the single clips.
The improvement in the spring D (the spring being old) consists in making a cup-shaped end, D, (see Fig. 1,) which sets against and partly incloses the round rear end, 6, of the thill, and thus prevents thejarring and noise consequent on the use of springs of this curved character when the flat end merely presses against the rear of the thill, and which causes the very rattling which they are intended to prevent.
My improvement is important, as it greatly strengthens the coupling and effectually pre-
