CAR-COUPLING.

SPECIFICATION forming part of Letters'Patent No. 441,494, dated November 25, 1890.

Application filed September 25, 1890. Serial No. 366,179.- (No model.) I

To all whom it may concern:

Beit known that I,WILLIAM P. LAMP, a citizen of the United States, residing at Brownsville, in the county of White and State of Illinois, have invented certain new and useful Improvements in Car-Couplers; and I do 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 same, reference being had to the accompanyin g drawings, and

to the letters of reference marked there0n,-

which form a part of this specification.

My invention relates to that 'class of carcouplers which are designed to be operated from the sides or top of the car with a View to the safety of the operator; and it consists in a novel device for eifeeting this result.

Figure 1 is an end elevation of a railwaycar provided with my invention. Fig. 2 is a side elevation of two draw-heads and couplers,

partly in section.

In the figures, A is one end of a railWay-car and B is the draw-head, having the recess a and the hole a to receive the ordinary coupling-pin, when required.

C is the coupling-bar, having the arrowheads e and the hooks e' which engage with the hooks 6 within the draw-heads.

D is a stirrup, which enters the draw-head through the grooves a', and which passes beneath the spring said spring being suitably attached to the bottom of the recess a and acting as a lever to lift up the couplingbar in the act of uncoupling the cars. The spring a is suitably attached to the top 'of the draw-head recess and declines inwardly, so as to catch the coupling-bar when inserted and press it downward in position for the engagernent of hooks e' and 6 E is an uncoupling-rod, horizontally crossing the end of the car, having the crank c and the handles c', and working in the bearings 9 The chain a connects the stirrup D and the crank H is a vertical rod, suitably attached atits lower end to the crank c, with its upper end reaching the top of the car and passing through the slot b in the guide-bar I, which is attached to the end of the car near its top.

b is a notch 'on one side and b' is a spring on the other side of rod ll near its top.

G is a tripping catch or dog, suitably fastened to the guide-bar I and operated by the releasing-rods F, the lower ends of which are supported by the standards d.

My device operates in the following manner, namely: To couple the cars, the couplingbar is inserted in the recess of the draw-head, where it is received by the upper spring and pressed downward by it into position for engagement With the hooks of the draw-head. To uncouple the cars, the handle of the transverse uncoupling-bar is turned and the crank raises the stirrup, which in turn raises the lower spring in the recess of the draw-head, which lifts up and disengages the coupling bar. When thus disengaged, the vertical bar has also been raised by the crank and is thrown by the spring attached to it into position for the engagement of the notch with the top of the guide-bar. When the crank -handle is released, this engagement is effected, and the coupling-bar is held firmly in position for the separation of the cars. To set the device ready for coupling again, the releasing-rod is pnlled downward, the vertical bar is thrown out of engagement by the dog and drops downward, and the springs in the draw-head recess are thus released and return to their normal positions, as seen in the right-hand draw-head of Fig. 2.` The device is also operated from the top of the car by raising or lowering the vertical bar by means of a suitable landle attached to its top.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a'car-coupler, the combination of the draw-heads, the coupling-bar having arrowheads and hooked ends, the upper and lower springs in the recess of the draw-heads, and the stirrup passing beneath the lower spring, substantially as and for the purposes deseribed.

2. In a car-coupler, the cornbination of the transverse rod having a crank attached to a ear, the stirrup suitably attached to the crank, and the vertical bar attached to the crank, working in a suitable guide-bar and having a spring on one side and a notch on the other near its top, substantially as and for the purposes described. v

3. In a car-coupler, the conbination of the IOO attaehed to the transverse hm' having& crank, the vertical bar having a spring and noteh near its top attached to the cmnk and working in a suitable guide-bar, and the trip catch 01' dog operated by 'eleasing-rods, substantially as and for the purposes described.

In testmony whe'ecf I affix m y si gn ttu PO in presence of two witnesses.
