JAMES S. WELUH, OF DODGE CITY, KANSAS.

THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 232,580, dated September 21, 1880. Application filed July 9, 1880. (ModeL) To all whom it may concern:

Be it known that I, JAtms SUMNER WELCH, of Dodge City, in the county of Ford and State of Kansas, have invented a new and useful Improvement in Carriage-Clips, of which the following is a specification.

My invention relates to a mode of attaching thill's to axle-trees.

In the accompanying drawings, Figure 1 is a top view illustrating my invention. Fig. 2 is a vertical section taken in the line a: w of Fig. 1. Fig. 3 is a vertical section taken in the line 3 y of Fig. and in a direction transversely to Fig. 2. Fig. 4 is a detail view.

A represents the axle-tree of a carriage of any suitable description; B B, the thills, and G the cross-bar connecting the rear portions of the thills. D is the axle-clip, which may be of the usual or any suitable description.

E is the thilLiron, which may also be of the usual description, with this exception: the socket or portion which receives the couplingbolt is taperin g instead of cylindrical, and the bolt is of corresponding tapering form. The tapering coupling-bolt G is passed through the lugs of the axle-clip D and through the socket of the thill-iron E, and secured by a nut, f, in

the usual manner.

H (see Fig. 4) represents a spring, which is formed of a strip of elastic sheet metal bent double about midway of its length. one

end of the spring is an eye, h, and at the other Y so as to have a tendency to force the bolt G and the thill-iron E in opposite directiousrectilinearly with relation to the longitudinal axis of said bolt. By this arrangement and combination of the spring with the bolt, the clip, and the thill-iron, the bolt is made to constantly fit nicely in the socket, rattlingis prevented, and the wear of the bolt and socket is automatically compensated for.

The portion of the bolt near the head may be squared to prevent it from turning.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In thin-couplings, the V-spring H, having a fork, if, at one end, to straddle the bolt between the inner side of clip-lug and the contiguous side of clip, while the other end is secured between nut f and said clip-lug, as shown and described.
