CAR-COUPLING.

`sr'EcIFIoAcIIoIv forming part of Letters Patent No. 277,300, dated May e, 1883.

Application inea March si, 1883. (No model.)

' To all whom it may concern:

Be it known that I, JOHN C. LOOK, a citizen of the United States, residing at Yuba City, in the county of Sutter and State of California, have invented a new and useful Improvement in Gar-Couplings, of which the following is a specication.

My invention Vrelates to improvements in car-couplings; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claims. y

Figure 1 is a side elevation of my improved car-coupling. Fig. 2 is a plan view of the same. Fig. 3 is a top view of parts of two cars in the act of coupling. Fig. 4 is a similar view of two ears coupled, and Fig. 5 is an elevation of one of the hand coupling links.

In the accom panyin gdrawin gs, a represents the draw-head of a car-coupling composed of .two parallel horizontal plates, a a', connected by studs c, each plate being provided with a hook, b, on each side of it. The plates a are connected in front at their middle by a plate, a2, having a link-opening, a4. The draw-head on one car is similar to that on the car with which it is coupled, so that a description of one will answer for both.

d represents avertical shaft adapted to engage loosely in the opening in the hooks b b on one side of the draw-head, and carrying a series of parallel horizontal bars, c o. The bars c c are enlarged andproje'ct outwardly at their front ends, and are connected together by the upright e, passing through the enlarged parts of the bars, forming a grid, d'. By this construction the grid or series of bars c c is pivoted to the draw-head in the aperture in the hooks l) b, on one side of it.

To one ofthe bars c', and on its outer sides, is a lug, f, to which theforward end of a strap, g, is pivoted, the rear end of the strap being pivoted to a rod, h, passing through holes in the opposite ends of a box, ,vsecured to the frame of the car. j represents a spiral spring secured to that part ot' the rod h lying within the box, the tension of which is always exerted to throw the rod forward and couple the cars.

The bar c of the grid d is provided on its inner face with a cam projection, a3, which in with a capstan, m, whereby the cars are un- I coupled, the enlarged front portions of the bars e o engaging with the hooks b b of the op` posite draw-head when the cars are coupled, and the bars c c or grids being arranged diagonally on opposite sides of the draw-heads on the carsto be coupled. f

The rear end of thebar c is provided with a tail end, c3, to which is connected by a link a wing, k, pivoted on a pin, c7, in the drawhead.

As the grid composed ofthe bars c c is uncoupled by operating the capsta-n the tail end strikes one ofthe pins c4, which acts as a stoppin, the wing k turning outwardly on its pivotal pin c7, and pushing the bars c or grid d on the draw-head of the adjacent car from engagernent with the hooks, thus uncoupling the cars.

n represents an auxiliary spring on the front end of the rod h, between the front end of the box i and a ring, o, sliding on the front end of' the rod, the function of the auxiliary spring being to operate on the rod h after the bars c c on one side have been uncoupled from the hooks.

A series 0f bars, c c', forming a grid is employed to adapt the coupling of cars of' different heights.

c5 represents a stop-pin, to prevent the wing k from being thrown too far outwardly by a lug, e6, on the wing striking against the stoppin c5. It will be seen that in this construction an ordinary link and coupling-pins may also be employed, if desired.

p represents a grid composed of two uprights, p p', connected together by three parallel horizontal bars, p2.

If it is desired to couple by hand, the grids p, as vshown in Fig. 5, can be employed by passing them around the hooks of the adjacent draw-heads and securing them in place by means ot' the pins p3, passing through holes in the ends of the hooks.

Having thus fully described Vmy invention, whatI claim as new, and desire to secure by Letters Batent, is-

l. The combination, with the draw-heads a, composed of parallel plates a', provided with hooks b b and studs c4, of grids composed of a series of parallel horizontal bars engaging in the opposite hooks of the draw-heads, substantially as described.

2. The combination, with draw-heads pro` vided With sidehooks, b b, ofthe grids d", placed loosely in engagement with the hooks and adapted to have a limited longitudinal play therein, substantially as shown and described.

3. The grid d', composed of the shafts or uprights d e and parallel bars having ont- Waltllyprojecting' enlargements at one end, substantially as described.

4. The draw-head a., composed of the parallel plates a', having hooks b formed in the sides of cach, the plates being connected together by the parallel studs c, and front plate, a2, having link-opening a, substantially as described.

5. The combination, With the front plate, a2, of the draw-head, of the bar c of the grid, provided with the cam projection a3, substatitially as described.

6. In a car-coupling, the wing 7c, pivoted in scribed.

8. The combination, with the wing k, pivoted in the draw-head and provided with thev the auxiliary spring fn, substantially as delugvo, of the stop pin c5, substantially as described.

9. The combination, with the draw-head a., provided With hooks b, having holes near their ends, ot' the hand-grids pand pins p3, substantially as described.

4l0. The combination, with the draw-head a, constructed as set forth,ot` the grid [1',having the baro', provided with the cam projection a3 and tail end c, wing 7c, pivoted in the drawhead, strap g, rod h, provided with the springs ja, capstan m, and chain l, substantially as described, and for the purpose set forth.
