'[CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 293,899, dated February 19, 1884. 7

Application filed November 12,1983. (No model) Knights Ferry, county of Stanislaus, and

. down upon it.

State of California, have invented an Improvement in Oar-Couplings; and'I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful carcoupling of that class in which swinging latches on each draw-head are adapted to fall into engagement with the ends or heads of the coup ling-pin.

My invention consists in a peculiarly-constructed draw-head chamber in a staple secured to the under side of the gravitating latch, adapted to receive and throw out the coupling-pin when necessary, and in the means for raising the latches from above or on the side to uncouple the cars, all of which I shall hereinafter fully explain, reference being made to the accompanying drawings.

Figure 1 is a perspective view of my drawhead applied to a car, and the means for raising the latch. Fig. 2 is a vertical longitudinal section of the draw-head, showing pin in position. Fig. 3 is a top View of the draw-head, showing the'latch raised to show staple E. Fig. 4 is a side elevation of the draw-head, a

I portion being broken away to show the coupling-pin in position, its {head in engagement with the shoulder b, and its point in staple E.

The object of my invention is to provide a simple and effective automatic car-coupling, which shall be able to readily uncouple itself in case of accident, or be easily uncoupled by design.

A is the end of a car, and B is a draw-head connected therewith in suitable manner.

0 is the latch, which forms also the top of the draw-head and completes the draw-head chamber 1), which is formed in the under surface of the latch and the upper surface of the body of the draw-head. This chamber is formed with the usual flaring entrance, and has an encircling shoulder b, behind which the enlargedconical head d of the couplingpin D fits. The latch O is hinged to the drawhead, and is adapted by its own weight to fall head forces up the latch sufficiently to allow it to pass under until its head fits behind the The pin D entering the drawup the end or point of the head of the pin,

carrying said head out of engagement with the shoulder 72 and thus uncoupling it. This operation would result in case of an accident which would tend to raise the latchsuch as a derailment, where the relative position of adjoining cars would be changed. The raising of the latch would throw the coupling-pin out, and thus by uncoupling the cars would prevent one dragging another off the track; but it is obvious that this ready adaptability to uncouple may be utilized by design, as

when the brakeman wishes to uncouple the cars. I have therefore shown means by which the latch may be raised to accomplish this result, both from the top and side. v

Pivoted to the sides of the latch are arms F, the lower ends of which are pivoted to levers G, having their forward ends pivoted to the sides of the draw-head near the front.

H is a frame or bail, the sides of which pass down on each side of the rear end of the drawhead. Upon these sides are loosely fitted the rear ends of levers G, being prevented from falling off by heads h on the lower ends of the sides of the bail.

To the top of the bail is secured a rod, I, passing up through a guide-staple, J in the end of the car near its, top. This-rod is provided with a hand-loop, i, on top, and a catch, 6, farther down. By raising this rod the bail H is raised, lifting the levers G and the arms F, which lift the latch G, to uncouple the de vice. The catch 2" of the rod I, engaging with the staple J, holdsthe rod up and keeps the latch raised, when desired. It will be observed that though the elevation of the rod I raises the latch the movement of the latter does not affect the former, because the rear loosely on the sides of the bail. entrance of the coupling-pin under the latch and raising it slightly does not aii'ect the bail or rod at all.

In order to uncouple from the side of the car, I hrvc a long lever, K, fulerumed at k, and pivoted on the rod I.

In the bottom of the draw-head chamber I make a hole, m, to permit the escape or discharge of sand, dust, grit, and other foreign material.

The other part of the deviee-namely, the opposite draw-head-is a duplicate of the part described, and the coupling-pin is alike at both ends; but if a car provided with my eoup ling should have to be used with a car having the old style upon it, I could make a pin with a conical head at one end and a link or slotted head at the other.

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

1. In a earcoupling, the draw-head B, hinged latch 0, between which and said drawhead a chamber, b, having a front shoulder, 12, is formed, for the reception and engagement of a coupling-pin, as described, in combination with the means for raising the latch, consist ing of the pivoted arms F, levers G, bail II, and red I, substantially as herein described.

2. In a carcoupling, the draw -head B,

Therefore the hinged latch 0, between which and said drawhead a chamber, Z), having a shoulder, b, is formed for the reception and engagement of a coupling-pin, D, and the staple E in the latch, for the reception of the point of the bin, in combination with the means for raising said latch and staple to free the pin, consisting of the pivoted arms F, levers G, bail II, and red I, substantially as herein described.

3. In a car-coupling, the draw-head B and hinged latch C, for receiving and engaging the coupling-pin, in combination with the arms F on the latch, the levers G on the draw-head, the bail II, upon the sides of which the rear ends of lever G loosely play, and the rod I, substantially as and for the purpose herein described.

4. In a car-coupling, the draw-head B and swinging latch O, forming a chamber, with a shoulder for the reception and engagement of the coupling-pi n D and the staple E in thelatch, in combination with the means for raising said latch from the side of the ear, consisting of the arms 1 levers G, bail H, red I, and lever K, substantially as herein described.

In witness whereof I have hereunto set my hand.
