WHiFFLETREE-COUPLING.

EPECIFICATION forming part of Letters Patent NO. 320,313, dated June 16 1885.

Application filed April 13, 1885.

T aZZ whom it may concern:

Be it known that I, \VILLLUI S. \VARD, of Plantsville, in the county of Hartford and State of Connecticut, have invented certain 5 new Improvements in \Vhifllctree-Couplings; and I do hereby declare the following, when taken in connection with accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of 1 the same, and which said drawings constitute part of this specification, and represent, in Figure l, a rear view of the whiifletree bar and plate, showing the coupling; Fig. 2, a

vertical central section through the coupling, showing the bolt; Fig. 3, an under side view of the plate attached to the whiffletree; Fig. 4, a top view of the socket attached to the whiiiletree-bar, broken lines indicating the method of applying the whiltletree to the bar.

This invention relates to the device by which a whiffletree is coupled to the whiifletreebar of a carriage, the object being the construction of the coupling so that the whiffletree may be readily detached or applied as occasion may require, and at the same time form an easy but anti-rattlingjoint upon which the whi'ffletree may play; and the invention consists in the construction, as hereinafter described, and more particularly recited in the claims.

A represents the whilfletree, B the whilfletree-bar.

On the whiffletreebar the socket C is so cured. This socket is a plate of metal having a central, preferably angular, opening, a, through it, and surrounding this opening a is a recess, Z). A flange, (1, around the central opening, extends above the upper plane of the socket, and from one side of the socket, say, 0 the rear, is a horizontally-projecting flange, D. Into the recess 1) a ring of india-rubber or other suitable spring, 6, is applied, and pre ferably upon this spring a thin metal washer, f, is arranged, as seen in Fig 2.

On the whiflietree A a plate, E, is fixed, corresponding to the socket, and as seen in Fig. 3. Centrally through the plate is an opening, it, corresponding to the flange (1 surrounding the central opening through the socket, and so that the flange on the socket may enter the opening in the plate, as seen in (X0 model.)

Fig. 2. In the whifl'letrce, above the opening in the plate, a recess, Z, is formed.

F is the whit'lletreebolt. This bolt has a head, m, and its neck n is of angular shape, corresponding to the angular opening a in the socket. before the plate E is fixed to the whiflietree, with its head in the recess Z in the whifl'letree, and as seen in Fig. 2. An opening is made through the whifl'letree-bar corresponding to the opening in the socket, and through which the bolt extends. The lower end of the bolt is screw-threaded, and upon this screw-thread a nut, G, is applied. From the plate E ahookshaped extension is made, say to the rear, corresponding to the flange D on the socket, and so that when set together, as seen in Fig. 2, the hook-shaped projection on the plate E will engage with the flange D of the socket, as seen in Fig. 2.

The whiftletrce is applied by turning it to nearly right angles to the whillletree-bar, and so that the hooked projection H may pass down to one side of the socket. Then when the hooked portion has arrived into the plane of the flange D the whifl'letree is turned to take the hook portion H into engagement with the flange D.

The extent of the flange D is sufficient to prevent the ordinary working ol'the whilfletrec from taking the hook out of engagement with the flange. The flanged on the socket, there fore, forms a central bearing on which the whiffletree may oscillate, while the flange D prevents the whiflletree from being lifted from its position on the socket. At the same time the bolt F draws the whillletree down upon the spring in the socket with suflicient force to prevent rattling, but not to interfere with the proper working of the whilfletree.

No strain comes upon the bolt other than that induced by the pressure upon the spring, the draft being taken entirely by the socket on the one part and plate on the other.

This coupling is applied by simply boring a hole through the one part for the bolt and a recess for the head of the bolt in the other part, the plate and the socket each being secured to its respective part independent of the bolt, as indicated in Figs. 3 and at.

Instead of applying the bolt with its head It is introduced through the plate E in a recess in the whiffletree, it may be passed through the whiflietree with its head on the top of the whiifletree, in the usual manner of whiffletreebolts; but I prefer to arrange the head as I have first described.

I am aware that whiffietree-couplings have been constructed in two parts, the one with a recess and the other with a correspondingtrunnion-like projection to enter the said recess and form a bearing on which the plates may turn, the trunnion adapted to interlock with the recess; but I make no claim to such construction.

I claim 1. The combination of the socket 0, constructed with a central opening through it, flange (Z around said opening extending above the plane of the plate, and also constructed with a recess, I), around said opening, and also constructed with a flange, D, extending from one side in a horizontal plane, the said socket being adapted to be attached to the one part, with the plate E constructed for attachmeat to the other part, and with a central opening, h, corresponding to the flange d in the socket, and with a hook-shaped extension, H, corresponding to the flange D on the sock et, a spring in the recess on the socket on which said plate will bear, and a bolt adapted to bind said plate upon the socket, substantially as described.

2. The combination of the socket 0, constructed for attachment to the Whiffletreebar and with a central opening, a, and with a flange,d, around said opening projecting above the plane of the socket, and with a recess, b, around said opening, and also withv a flange, D, projecting from the socket in a horizontal plane, the plate E, constructed for attachment to the whiffletree, and witha hook-shaped projeetion, H, corresponding to the flange D on the socket, and with a central opening, h, corresponding to the flange around the opening in the socket, a spring in said recess upon which said plate will bear, the bolt F, having its head adapted to bear upon the said plate, its neck of shape corresponding to the opening in the socket and adapted to pass through the.
