vSPECIlICA'lION' forming part*v of Letters `:Patent No. 273,326, dated March 6, 1883.

Application led January 4, 1883.

To all whom it may concern:

Be it known that I, JOHN H. WARD, of Lowell,in the county of Middlesex, State of Massachusetts, haveinvented acertain new and useful Improvement in Car-Couplers,of which the following is a description sufciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and usethe saine, reference being had to theaeeompanying drawings, forming a part of this specification, in which- Figure l is a side elevation; Fig. 2, avertical longitudinal section, and Figz a top plan view.

Likeletters of reference indicate correspondingpartsin thedii'erentigu res ofthe drawings.

My invention relates more especially to that class of car-couplers which are automatic or seltcoupling in their operation vand it consists in a novel construction and arrangement.

of the parts,as hereinafter more fully set forth and claimed,by which a cheaper, simpler, and more effective device of this character is pro duced than is now in ordinary' use.

rlhe nature and operation of the improvement will be readily understood by all conversant with such matters from the following description, its extreme simplicity rendering an elaborate explanation unnecessary.

In the drawings, A A represent the drawbars, and B the link. The draw-bar heads are each provided. with a longitudinal chamber, O, having a flaring mouth, m. The rear portion., d, of each of the chambers opens through .the under side of the draw-bar head, and journaled therein on the shafts D are two cam-shaped levers, E, each provided with an outwardlycurved upwardly-projecting arm, G, and at their lower ends with the toothed segment f. The shafts extend horizontally through the draw-bar heads, and are provided at their ou ter ends with the hand-wheels H, being tirmly attached to the levers E in the chamber U.

Disposed on each ofthe shafts D, on either side of the draw-bar head, there is a ixed curved lever, J, and coiled spring K, one end of the spring being secured tothe shalt and the other to a laterally-projecting pin, L,which pin is also elongated and acts as a stop l'or the (No model.)

draw-bar heads, as shown by the dotted lines in Fig. 3.

In the use of my improvement, one of the draw-bar headsbeing rst provided with a link, B, if the cars are brought together, the free or outer end of the link will enter the cham- .ber C in the opposite orcornpanion head, strike the curved or outer face of the arm G, forcing it back, and, passing downwardly, hook over the pin L in the throat of the draw-bar head, thereby coupling the ears in a manner which will be readily obvious without a more explicit description. The springs K are so arranged as to force the arms G of the levers E against the hooks Z of the link B, therebyl keeping the hooks engaged with the pins L after the cars are coupled, or preventing the ears from being accidentally uncoupled, the arms being curved and extending over the hooks,as seen in Fig. 2.

Attached to the outer end of each of the levers'J there is a chain, M, extending to the platform or top of the car, and by pulling these chains the arms G will be forced away from the hooks l, and at the same time the teethf on the levers E will be caused to engage the teeth u on the hooks l, thereby disengaging the hooks from the pins L, raising the link B, and unconpling the ears. v'lhe ears may also be uncoupled in substantially the same manner by turning the `wheels H, if preferred or more convenient. i

It will be obvious that the pins L perform a triple service, acting as stops for the levers J, studs for attaching the springs K, and staples for the hooks Z, and when worn by the action ofthe hooks may be readily removed and new pins inserted.

The throat of the draw-bar head is so formed ati as to re-enforce or strengthen the pin,

which in turn prevents the wear of the throat by the action ofthe hooks.

Having thus explained my invention, what I claim is 1. The improved car-coupler described, the

same consisting or" the link B, provided with the serrated hooks l, the drawbar heads A, provided with the chambers G d and pins L, the levers E, provided with arms Gand teeth 5 f. and the shafts D, provided ivith the levers J, springs K, and Wheels H, construoted,com bined, and arranged to operate substantially as set forth.

2. In a oar-coupler substantially such as dero scribed, the pin L, arranged to serve as a staple for the hook i, a stop for the lever J, and a stud forthespring K,substant ially as specified.

3. In acum-coupler, substantially such as described, the link B, provided with thehooks Z, 15 in combination with the curved yieldinglever G, adapted to receive the end-thrust of the link, turn its free end down into engagement vwith the pin L, and hold it in Contact. therewith, substantially as described.

4. In a car-coupler substantially such as described. the levers J, provided with the chains M, mounted on the shaft D, provided with the springs K, substantially as set forth.

5. In a car-coupler substantially such as described, a link having.r two downwardly-projeotinghooks for engaging the draw-bar heads, and provided with serrations or means whereby they may be lifted out of engagement therewith, substantially as specified.
