CAR-CCU PLlNG.

SPECIFICATION forming part of Letters Patent No. 515,830, dated March 6, 1894.

Application filedApril 19, 1893.

nying drawings.

My invention relates to car-couplers and it consists in the improvement hereinafter described, illustrated in the accompanying drawings and especially pointed out in the claims.

The object of my invention is to provide an automatic coupling which will be simple in its construction, strong, easily operated and which will accommodate itself to grades and curves.

In the drawings, Figure 1, is a longitudinal section of my improved couplers showing the drawheads connected by a ball and bar link, and the buifer, uncoupling levers and actuating mechanism in position. Fig. 2, is a perspective view of the drawhead, showing the lever for disengaging the link whpn the cars are to be uncoupled. Fig. 3, is an end elevation of the drawhead. Fig. 4, shows a modified form of link to be used when coupling with the pushing bar of a locomotive.

Referring to the several parts by letters of reference, A A are opposing drawheads which open longitudinally downward, said I opening extending backward to the drawbolt attachment, not shown. This opening is however bridged at f, the bridge serving to keep the buffer bar B in place and to form an abutment for the bnifer spring 6; the opening in the front part of the drawhead is made flaring, the two sides forming heavy lips or flanges a. which approximate each other so closely as to leave but little more space than is necessary for the passage of the bar of the draw link; back of the lips or the opening is Serial No. 470,983. (No model.)

changes of grade. The opening below the lips is enlarged so as to receive the bufier bar and hold it in position at its forward end. This bar is provided with n raised portion B from which projects a rod e carrying the bulfer spring 6, the upper face of thepart B being slotted and fitted with a lever 11 pivoted at b and provided with an eyelet bolt 0 to which is secured a chain c that leads to any convenient part of the car for operating the lever b when uncoupling. The slot in the upper face of the projection of the buffer bar is beveled outward upon each side so that the ball on the link will be allowed to gradually take position behind the lips a when the bulfer is forced back in coupling. This slot is bridged near the front with a wire or rod 61 which limits the upper movement of the lever 1). The under portion of the drawhead is slotted and provided with levers g 9' adapted to force the buffer bars back against the springs e by hand whenever occasion requires it.

The operation of my coupler is as follows: The buffer bar is forced back by hand and one end of the link it is positioned behind the lips a, when the bars B are released and the projection B coming against the ball, binds it between said projection and the lips, thus creating sufiicient friction to hold the link in any position at which itmay be placed; the link is then elevated as indicated in dotted line and the cars are brought together when the buffers striking take the pressure 0d the link and the ball drops from its elevated position into the beveled groove in the projection of the buffer bar of the opposing drawhead, and from there to position as the cars are drawn more closely together, thus automatically coupling them. hen it is desired to uncouple the cars they are backed until the drawheads are forced against the springs e, when by raising the lever Z) by means of the chains 0 the ball of the link will be thrown from its position and the cars may be separated.

When it is desirable to use the pushing bar of the locomotivel use the form of link shown in Fig. i, with a ball on one end and a link on the other.

IOC

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is i 1. In a car-coupler, opposing drawheads and means for connecting the same .by a link consisting of a bar having spherical ends, in

combination with a bufier bar having an up-;

ward projecting portion, and a beveled groove in said portion by which the fall of the link is broken, and it is permitted to assume posi-.

which rests under the ball end of the bar link, as and for the purpose specified, substantially as described.

3. In a car-coupler the combination of the drawhead opening in front, and upon its upper face, of the inwardly protruding lips, and

the buffer having an upward projecting portion with beveled groove held to position beneath the same, said groove containing a pivoted lever of the spring to normally hold the buffers in a forward position, and the link having spherical ends with the lever and connecting mechanism for coupling and uncoupling, substantially as set forth.

In testimony whereof Iaflix my signature in presence of two witnesses.
