To CLZ 1,071,077?, t nw/y concern,.-

Be it known that I, CHARLES E. C. EDEY, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of XVashington, have invented cert-ain new and useful Improvements in Car-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the sanne.

My invention relates to improvements in car-couplers, and more particularly to the Janney type, which employ knuckles provided with a pivoted jaw; and it consists in a coupler having a pivoted jaw, the said jaw having' a rearwardly-extending arm adapted to be locked in the coupler, and means upon the said arm for removing the strain from the pivot-pin of the coupler and preventing the jaw from rocking.

lt also consists of certain other novel constructions, combinations, and arrangements of parts, as Will be hereinafter fully described and specifically claimed.

Figure 1 represents a horizontal section through the said coupler, the lockingjaw being closed. Fig. 2 represents asimilar view, the locking pivoted jaw being open. Fig. 3 represents a perspective view of the said jaw, and Fig. 4 represents a detail view showing the means for strengthening the said jaw when in its closed position.

l iu the drawings represents the draw-head of the coupler, 2 a pivoted or locking jaw, and 3 a pivot-pin.

In couplers of this type there is a great deal of strain brought to bear on the pivotpin of the locking-jaw, and it is very'desirable to provide means in the draw-head which will serve to remove a great deal of strain brought to bear upon the said pivotpin.

With this object in view my invention is designed to so form the pivoted locking-jaw of the portion of the draw-head in which it is mounted that the parts will be more or less interlocked when closed, and strength will thus be aiorded to the structure. The pivoted jaw 2 is provided upon its rearwardly extending arm or tailpiece 4 with a projection or lug 5, preferably cast integral therewith. This projection 5 is adapted to engage a correspondinglyeshaped socket or recess 6,

lforce.

formed upon the inner surface of the wall of the draw-head. The projection 5 is formed thicker and wider at its outer end 7 than it is at its inner end 8, so that when it tits into the corresponding socket 6 it will form a dovetail joint with lthe wall of the coupler and be -able to withstand shocks of great It will be seen `that this device may be applied to any coupler of. the ordinary Janney pattern and that the projection 5 will not only be shouldered against the abutting face 9 ot' the socket 6, but, because of its dovetail shape, it will prevent to a great eX- tent any rocking m'otion of the pivoted jaw upon its pivot-pin. So, also, the projection 5, because of its dover-ail connection with the draw-head, will sustain a pulling strain as Well as a pushing strain.

It will be observed that the parts are so constructed that the strengthening -joint formed between the projection 5 and the socket 6 does not in any way interfere with the use and usual manipulation of the pivoted jaw in the operation of coupling and uncoupling two couplers. It desired, the projection 5 may be made separate from the pivoted jaw and be bolted or riveted thereto. The socket 6 also may be formed in a piece which is sep'- arate from the draw-head and may be firmly Secured by rivets, bolts, or welded to the said draw-head without departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure byLetters Patent, is-

1. A carcoupler, comprising a suitable draw-head having a socket formed in one of its walls which is larger at the rear end than at the front, the said recess tapering from rea'r to front, a pivoted locking jaw mounted in said draw-head, a tapering strengthening projection formed upon said pivoted jaw adapted to fit into the socket. in thedrawhead when the jaw is closed, whereby strain will be removed from the pivot-pin of the jaw, substantially as described.

2. A car-coupler, comprising a draw-head, a pivoted jaw mounted therein, a rearwardlyextending locking arm on the said jaw, a strengthening wedge shaped projection j formed upon the said jaw adapted to tit in a correspondingly-shaped socket formed in one of the Walls of the draw-head, the said socket having a rea-r abutting face, and upper and lower limiting-farces, so that the projection on the pivot-ed jaw will be dovetailed therein, and so as t-o guard age-inst front and back pressure and any rocking of the pivoted jaw upon its pivot-pin, su bstantially as described.
