SPECIFICATION forming part of Letters Patent No. 510,949, dated December 19, 1893.-

Application tiled August 5,

-.Z0 all whom it any.concern:

Be it known that I, EDWARD W. WooLLEY, aresident of Jersey City, Hudson county, State of New Jersey, have invented an Improved Oar-Coupler, of which the following is a specification.

My invention relates to car-couplers and has for its object to produce a simple, cheap and reliable meansfor automatically coupling the cars of a railway train. I attain these ob- 160118 by the mechanism illustrated in the accompanying drawings, in which Figure l is a. side view of my improvement showing the operated parts in dotted lines. Fig. 2 is an end view thereof. Fig. 3 IS a section on line 3-3 of Fig. 2. Fig. 4 is a top View of the coupler showing by dotted lines the position of the coupling link in the drawhead. Fig. 5 is a detail view of the coupling pin. Fig. 6 represents an apparatus for holding the pin in an elevated position when desired. Fig. 7 is a section on line 77 of Fig. 6.

A represents an ordinary form of drawhead for railroad cars, and B a standard link adapted to enter and be secured therein.

0 represents the pin which enters the link in the usual manner to complete the coupling. Pivoted at it, in a recess 1) in the drawhead, is a bell-crank 0, one arm of which extends into the recessD in the drawhead in the path of the link and is slightly rounded. To the other arm of the bell-crank is pivoted one end of a link d, the other end of which is pivoted in a recess e in the pin 0 and co-operates with the bell-crank to lift the pin. The pin 0 works in a way f extending vertically through the drawhead. The pin is provided with shoulders gg to act as stops when the pin has been dropped in the way in the drawhead. A recess h is provided in the pin 0 for the reception of the rounded end of the bell-crank lever, and also to fit over and engage the projection 't' in the Way f, which forms a bearing to prevent lateral play, and to steady the pin. The pin is slightly hollowed. or notched transversely on its rear face as atj, to form a seat forthe link, and to prevent the pin from being lifted by the link in its unavoidable movement due to the jarring and the sudden variation of tension when 1893.

- stopping and starting the train. It willbe seen that the pivot it extends entirely through the drawhead so as to be readily removable,

moved, and the broken or worn out parts replaced. The drawhead may be made in the usual manner, as by casting. The remaining parts I prefer to makeby drop forging.

The operation is as follows: The parts are in the dotted line position of Fig. 1, and a link is approached in the manner shown in full lines in said figure. This link in the act of coupling is fast in the coupler of another car. The link is thrust into the recess D and strikes against and rocks the bell-crank lever. This by means of the link (1, lifts the pin 0 to clear the link B in its entry. (See Fig. 2.) As the link is pressed home the bell-crank lever falls into the aperture in the link and allows the pin 0 to also fall into the same aperture, and prevent the link from being withdrawn from the .drawhead. The parts are now again in the position shown in dotted lines in Fig.1. To nncouple, the pin may be lifted in any suitable manner, as by engaging the eyel with some such device as is represented in Figs. 6 and 7, and the link withdrawn from the drawhead. When the pin has been lifted high enough to clear the link, the rounded end of the bell-crank will enter the recess h in the pin and be thereby protected from injury as the link is withdrawn.

As it is often desired to hold the pin in an elevated position to hold the parts out of operation, I have shown a device for the purpose in Figs. 6 and '7. The rod 0 is mounted in brackets q on the end of a car, and has fast thereon a sheave s over which passesa chain or cord m attached to the eye 1 of the pin. Handles r on the rod 0 serve to rotate itto wind the chain and lift the pin. hen it is desired to hold the pin in an elevated position after it has been raised, the rod 0 is slid longitudinally in the brackets in either direction and the pin p and cam stops it on the rod and bracket respectively come in contact and form stops to prevent the further rotation of the rod. When it is desired to lower the pin from this fixed position, the operation is reversed.

Having described my invention,1 claim- 1. In a car-coupler, the combination with a in order that the working parts may be re- IOC drawhead, of a bell-crank pivoted thereto,

having one arm extending into the path of a coupling link and adapted to be struck 'thereby, a pin for securing the coupling link'in the drawhead, and a link pivoted to the pin and to the other arm of the bell-crank, substantially as described.

2. In a car-coupler, the combination with a drawhead, of a bell-crank pivoted thereto, having one armextending into the path of a coupling link and adapted to be struck thereby, a pin for securing the coupling link in the drawhead,and a link connection between the pin and the other arm of the bell-crank pivoted in a recess in the pin, substantially as described.

3. In a car-coupling, the combination of a bell-crank c, pivoted in a recess 1) in the drawhead and having one'arm extending into the ated by one arm of said bell-crank, and hav- I ing therein a recess for receiving the end of the other arm of the bell-crank,substantially as described,
