CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 479,990, dated August 2, 1892.

Application filed March 11, 1892. Serial No. 424,573. (No model.)

To all whom it may concern.-

Be it known that I, JOHN P. RoLLINs, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Car- Ooupling, of which the following is a specification.

The invention relates to improvements in car-couplings.

The object of the present invention is to simplify and improve the construction of twin-jaw couplings and to enable the knuckles to be operated from the side of the car.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of a car-coupling constructed in accordance with this invention. Fig. 2 is a vertical 1ongitudinal sectional view. Fig. 3 is a horizontal sectional view.

Like numerals of reference indicate corresponding parts in all the figures of the drawlngs.

1 designates a draw-head, to which is pivoted by a knuckle-pin 2 a knuckle 3, and which is provided with a longitudinal opening 4, and having arranged therein a sliding latch-block 5, arranged to engage a shoulder 6 0f the knuckle, to hold the latter in engagement with a knuckle of a twin coupling. The latch-block 5 is slightly curved throughout its length and is arranged on inclined ways '7, which are curved to conform to the configuration of the latch-block, and the latter is withdrawn from the knuckle to allow the latter to be opened for uncoupling by a rockshaft 8, mounted on a car J and having an arm 10, which is connected with the latchblock by a chain 11 and a bar 12. The bar 12 is pivoted in a bifurcation of the latchblock and extends through a slot 13 of a casing 14:, arranged on the draw-head and receiving the upper end of the latch-block and adapted to protect the same when withdrawn from engagement with the knuckle. The upper end of the bar 12 is connected by the chain 11 with the arm 10 of the rock-shaft, and the outer end of the latter is provided with a handle 15, which is arranged at one side of the car to enable cars to be uncoupled Without going between them.

The knuckle is moved outward in position for coupling and to make the uncoupling positive by a sliding bar 16, arranged 011 the bottom of the draw-head and having its front end disposed between a shoulder or boss 17.

the draw-head, and a sliding bar is guided at.

this point by a keeper 24. The outer end of the rock-shaft is provided with a handle 25, by means of which the sliding bar is reciprocated. The knuckle is provided with the usual coupling-pin opening 26 and a link-recess 27 to enable the draw-head to be coupled with an ordinary pin and link.

It will be seen that the knuckle may be readily controlled from the side of a car without necessitating persons going between the cars.

NVhat I claim is f 1. In a car-coupling, the combination of a draw-head having a longitudinal opening and provided with slightly-curved inclined Ways,

a knuckle hinged to the draw-head,a curved latch-block arranged on the ways and adapted to engage the knuckle, a bar pivotally secured to the latch-blQck,and a rock-shaft connected with the bar, substantially as described.

2. In a car-coupling, the combination of a draw-head having a longitudinal opening and provided with a slot, a knuckle hinged to the draw-head, a sliding bar arranged to engage the knuckle and having a stem projecting through the slot, and a rock-shaft connected with the stem, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature'in the presence of two witnesses.
