cARl-coUPLlNG.

SPECIFICATION forming part of Letters Patent No. 365,739, dated June 2e, 1887.

Applicntionlcd December 20, 1886. Serial No. 222.096.

To all whom it may concern:

Be it known that I, PULAsKI FARwnLL, a citizen of the United States, residing at Fredericksville, in the county of Schuyler, State of Illinois, haveinvented certain new and useful Improvements in Oar-Couplers, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to car-couplers; and the object of the invention is to provide a coupler that will be sel f-coupling, and which may be uncoupled from the side or platform of a car, and also to obviate the use of a coupling-pin.

With these objects in view the invention consists in certain features of construction, hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure l is abettom plan of two cars, or portions thereof, provided with my improved couplers, said coupcouplers being in the act of coupling or uncoupling. couplers. Similar letters of reference indicate like parts in all the iigures ofthe drawings. f

A represents the bottom ofa car,and B-represents a bifurcated laterally-swinging drawhead,'which is formed with locking-lugs B', connected by locking bar or shoulder B2, and with a stop, B. Integral with the draw-head B is a draw-bar, B", recessed, as at B5, and pivoted to the car or any suitable adjunct thereof, as at B whereby the bar and head are given a lateral play or swing, which play islimited by a bail, G, embracing the headl and secured to the under surface of the car or platform.

' Pivoted within the recess of the head B, as at D', is a spring-actuated locking and unlocking lever, D, which is bifurcated, forming the retaining-arm D2 and the ejecting-arm D, the swinging movement of said lever bei nglimited by the bail C. Back of its pivot the lever is provided with a V-shaped recess, D, adapted to receive a flat spring, D", the opposite end of said spring bearing against a shoulder, B7, formed in the draw-bar, the tendency of the spring being to retain the lever in parallelism with the draw bar and head.

Fig. 3 is an end view of one of the (No model.)

At one side of the car is an operating-lever,

E, pivoted, as at E', to the car, and from thelever to the end of the lever D extends a chain, E2; or, if desired, the uncoupling may lbe accomplished by devices leading to the top or platt'orm.

This being the construction, the operation is as follows: As the draw-heads of two cars come in contact with each other, the lockinglug of each coupler next to the opposite coup- 1er passes between the bfurca tions of the opposite head,the lever D of each head heilig forced away from its draw-head by contact of its arm D2 with the opposite draw-head, so as to admit of the introductionof the lugs into the heads, whereby a double lock may be formed. After the lockinglug has reached a point back of the bar B2, the arm D2 of thelever D, aided by the `spring 13S-forces said lug into the chamber B5 back of the bar`B2, where it is held in a locked or coupled position by the arm D2 of the spring-pressed lever D, as clearly shown in Fig. 1. To uncouple the cars, it is only necessary to draw upon the lever E, which in turn draws upon the lever D, thus unlocking the head or opening it, as shown iu Fig. 2, the arm D3 of the lever forcing the locking-lug out of the chamber'. After the cars are uncoupled the parts will automatically assume their normal position by reason of the spring D,

If preferred, and for the purpose of facilitating the manufacture of the coupler, the draw bar and head may be formed of two plates and bolted at suitable points.

An ordinary pin-hole, X, may be formed for coupling with other styles of couplers.

Having thus fully described my invention l and its operation, what I claim isl. In a car-coupler, the combination of a draw-head pivoted to the car, the forward end being bifurcated and recessed, forming a locking-chamber, locking-lugs, and a locking-bar with a spring-pressed locking-lever pivoted within said chamber and bifurcated to form a locking and an ejecting arm, and with a bail embracing said head and lever for limiting the swinging movement of the lever and head, substantially as specified.

2. The draw-head B, pivoted, as at B", and formed with thelocking-lugs B,lockiugbarB2, chamber B5, and projection B7, in combination IOO with the iockinglevor D, formed with the V- to perform the double functions of a guide in io recess,a11dhaving a spring, D4, and pivoted, as coupling and Of an ejector in uncoupling, sub- I at D', and having arms D2 D3, and with the opstantaily as specified.
