CAR-COUPLING.

SPECIFICATION forming part of Letters :Patenta No. 263,&36, dated September 5, 1882.

e Aiplcation filed April 13, 1882. (No model.)

`wealth ot' Massachnsetts, have invented cer tain new and useful Inprovements in Car- Couplings, ot' which the following, taken in connection with the accompanying drawings,

is a specification.

This invention relates to an improvement in that class of car-couplings in which the cars are automatically coupled when brought together, and can be uncoupled without the ne cessity ot' the operator going in between the platforms. I

The object of the invention is to produce a simplified form of coupling which shall be positive in its operation, and to provide means whereby the same may be uncouplcd from the top ot' the car.

The invention consists in the hereinat'ter-described combination of the draw-head, the coupling-pin, and latch-lever adaptcd to automatically bear against the coupling-pin and hold it in position.

It further consists in the combination of the said latch-lcver with the draw-head and couplinglink. i

It also relates to the meclanism whereby the coupling may be operated from the top ot' the car.

-In the accompanying drawings, Figure l represents in side elevation a longitudinal vertical section of ny improved conpling applied to the end ot' a car. Fig. 2 represents in side elevation alongitndinal vertical section of my improvedcouplin g, and shows the relative position of' the parts while connected with the coupling-link. ot' Fig. 2.

The draw-head A is attached directly to the bottom of the car in the usual manner, and is provided with a mouth or chamber, B, that i opens inwardfrom the end ot' the draw-head and allows free entrance and play to the coupling-link'G. Opening out ot' the chamber B atits rear end is a vertical slot.which extends back into the draw-head A, and in this slot is arranged the latch-levcr D, which has its rear end pivoted on the pin e, and, reaching forward, bears its opposite end against the coup- Fig. 3 is a section on line mar ling-pin E. Said lever is further provided with an inclined end, b, and permits of sufficient vertical novement to allowthe end to be lifted away from the pin E. Said pin E is constrncted in the usual nanner, and operates vertically up and down through a hole in the draw-head. Said pin is connected with a rod, f, which 'eaches npward therefrom to the top ot' the car. The rod permits of vertical movement in its beariugs, and carries an adjustable pin, t, that, coming in contact with the hearing o, limits the upward movement of the rod.

From the foregoing description it will be evident that in order to unshackle the cars the worknan has only to lift npward the pin E (which may be done from the top of the car by means of the rod J) sufliciently to release the coupling-link G. The upward movement of the pin is limited by the finger t coming in contact with the bearingn, whereby the pin E is prevented from being lifted completely out of its socket. As the link C passes away from the latch-lever D the latch falls immediately onto the pin E, thereby cramping the pin against the draw-head A and holding it elevated, as shown in Fig. 1, and also that when the cars are brought together again for the purpose' ot' shackling, the link, coming in contact with the incline b, pushes Upward the latch D, thereby lifting it away from the pin E, which, when released, slides down to engage with the link G, as shown in Fig. 2. The latcl should be allowed to bear upon the end of the link when the same is in engagement with the pin E, and should be of sufficient weight to overbalance the portion ofthe link which projects from the draw-head A. By this means the linkis kept always in a suitable position to enter the draw-headon an opposing car.

It will be observed that the latch-lever is pivoted in a slot opening from the rear ot' the main chamber ot' the draw-head, and that this slot is Situated above the highest pointto which the rear end of the coupling-link can be elevated. The link,which is subject in use to constant strain and movement, thus hammers against the solid rear wall of the chamber B, and not against the latch-lever or the walls of the slot-,which are thus protected from injury. The lever'is thus enabled to move freely and IOO with certainty on its pivot. Were the blows of thelink brought upon the latch, there would be danger of breaking the same and of twisting and bending the pin upon which it is pivoted.

I am aware of the patent of Kelly, No. .249,7 72, which clearly shows the principle upon which my coupling operates. I wish to disclaim this principle, and to confine my invention to the specific improvement shown in this application.

What I claim as new, and desire to secure y by Letters Patent, is-

In a coupling, the combination of the chambered draw-head A, having vertical orifices for I 5 the coupling-pin, the coupling-link G, and the latch D, having curvecl face and pivoted in a slot opening from the real' end of the chamber in the draw-head, su'ch slot being situated above the level of the coupling-link, all sub` 20 stantially as described.

In testimony whereof I have signed this specification in presence of two witnesses.
