UNITED STATES PATENMFM AMANDUS WOEBER, OF DAVENPORT, lOl/VA.

Specilication forming part of Letters Patent No. l 52,447, dated J une 23, 1874; application filed December 12, 1873.

' which- Figure l is a front elevation. Fig. 2 is a vertical section taken on line s s of Fig. 1. Fig. 3 is a transverse section of the sockets, pivot, and king-bolt, as indicated by line cc cc of Fig. 1.

My invention relates to an improved carriage-couplingand king-bolt; and consists otl a cliphaving a socket to receive a pivotal socket on the head-block plate, and a kingbolt, which extends through the sockets and the head-block and springs'. The clip is made with broad tlanges, forming bearings to iit and rest 011 the wood part of the axle, and the socket and pivot are tapered, so as to be slightly larger at the top, and the pivotal socket extends entirely through the clipsocket and slightly below a recess formed at the bottom ofthe socket to receive the tlanged head ot' the king-bolt, so that the lower end of the pivot forms the bearin g ot' the head ot' the king-bolt, which is held in place by a nut on the top of the holt.

The object of the invention is to prevent the liability existingin ordinary couplings of twisting oit' the kin g-bolt.

A represents the clip, made with anges b to fit over the axle, and forming bearings sufficiently large to prevent wearing or sinking into the wood part of the axle B. A' is the clip-socket, provided with a recess, c, at the bottom to receive the flanged head of the king-bolt, and the socket is made to taper slightly, so that its diameter is slightly larger at the top than at the bottom. B' is a pivotal socket von the head-block plate C, which pivot is made slightly tapering to lit the socket A', and extends entirely through and sufriciently below the socket to form the bearing of the head of theking-bolt, as shown in Fig.

2 ot' the drawings. D is the king-bolt, having a flanged head, d, and the lower part of the bolt is square to fit the square part of its socket formed on the lowerA end of the pivotal socket B', as shown in Fig. 3, so that the bolt may not turn in but -with its socket. The bolt is held in place by a nut, c, on the upper end, by which the head d is tightly drawn against the lower end ot the pivot B', and the springs and head-block are firmly held on the coupling.

Instead of making the lower part ot' the bolt and pivotal socket square, the head of the bolt may be provided with a lip or lug to lit in a recess in the lower part of the pivot B', to prevent the bolt from turning.

AThe king-bolt is introduced at the bottom of the clip-socket before it is attached to the axle, and being arranged not to turn on its socket, and the head ot' the 'bolthaving its bearings on the end of the pivot, as described, the coupling may be tightened by screwing down the nut c to any required extent without att'ectii'ig in the least the free motion of the coupling, and without any liability, in use, of twisting oil the bolt.

I am aware that, there are clips provided with ianges and-with sockets; but none of them are constructed to receivea pivotal socket through which the kin g-bolt passes, as herein described.

What I claim as new, and desire to secure by Letters Patent, in carriage-couplin gs, is-

1. A clip-socket, A', in combination with a pivotal socket, B', and Vking-boltV D, substantial] y as and for the purposes described.

2. The pivotal socket B', in combination with the bed-plate C, clip-socket A', and kingbolt D, substantially as described.

3. The clip A, having anged bearings b, and clip-sockets A', having recess c, in combination with pivotal sockets B', plate C, and king-bolt D, substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day ot' November, 1873.

AMANDUS WOEBER. Witnesses E. M. BRAMsrcK,
