THILL- CDUPLING.
P.tent'ed May Z-',1876. I
GEORGE W. OOGSWELL, OF ROCHESTER, NEW YORK.
IMPROVEMENT IN THlLL-COUPLINGS.
Specification forming part of Letters Patent No. 176,773, dated May 2, 1876; application filed March 10, 1876.
To all whom it may concern:
7 Be it known that I, GEORGE W. OOGSWELL, of the city of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Thill- Couplings; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the samereference. being had to the accompanyingdraw, ings, in which-- Figure l is a sectional elevation. Fig. 2 is by a pin, 0, which passes through holes 0 c of the jaws. The pin 0 is provided on one side with a spline or feather, d, of just such length as will lit and ride between the jaws a a; and
the said jaws are provided with corresponding ofi'set slots ff, for allowing the'iusertion of the pin endwise. The slots ff are located either above or below (preferably above) the range of motion of the thill eye, so that, in ordinary use, the parts cannot become detached, yet
when the thills are fully raised or lowered the disconnection can be made. The thill-eye is also formed with a corresponding slot, g, in which the spline d rests, as shown in Fig. 1.
It will be seen that the spline 01 serves a double purpose: First, being connected with the thill-eye, the pin rides or turns with the eye, so that the friction comes within the jaws of the clip, and not between the thill-eye and pin, and, second, being made of just such length as to fit between the jaws and turn easily, it serves to retain the pin in place with-v in the jaws, thereby dispensing with nuts or any other attachments upon the pin.
G is a clamp or tightening-block, which is titted in the rear and below the thill-eye, and rests between it and the body of the clip. Its face It is made concave to fit the thill-eye, and on its back is a dovetailed rib, c, which fits and slides in a corresponding dovetailed groove, k, of the clip. On its upper end is a screw-stem, l, which passes up through a projecting bearing,m, and has upon its upper end a nut, n, by which it is raised or lowered.
By drawing up the follower at any time the thill-eye and pin can be packed, thereby preventing rattling and compensating for wear.
The nut may have a flange at the bottom, and the bearing m may have a corresponding flange, embracing the flange of the nut, whereby the nut is prevented from working off the screw.
I am aware that wedges, springs, and other devices are employed for packing the eye and bolt in thill-couplin gs. My device differs from such, in constructing the follower with the dovetailed rib t, and in attaching to the same the screw-stem l, by which the adjustment can be produced by turning the nut at the top.
The dovetail serves to keep the clamp centered and in proper position, and also to retain it'in place when the thills are removed. This clamp is much more effective than common wedges.
I do not claim, broadly, a coupling-pin which rides or turns with the eye of the thill. Neither do I claim, broadly, a wedge for tightening the thill-eye upon the pin; but
I claim The combination, with the clip A and thilliron B, provided with the feathered pin 0, of the clamp G, constructed with the dovetailed rib t and the screw-stem l, extending through the bearing m, and secured by a nut, n, as and for the purpose specified.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
G.-W. OOGSWELL.
