CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 292,698, dated January 2-9, 1884.

' Application filed December 5, 1883. (N model.)

. it has for its object to provide a safe and efficient automatic coupling in which there willbe no springs to get out of order by constantuse, and yet the operation will be positive and certain at all times.

It also has for its object to provide an improved device for raising the link in coupling with cars of different heights; and a still fur ther object of the invention provides means for automatically coupling cars employing the ordinary pin and link.

Withthese objects in view the said invention consists in certain details of construction and combination of parts, as hereinafter fully set forth, and particularly pointed-out in the claims.

In the accompanying drawings, Figurel is a perspective view of my improved car-coupling. Fig. 2 is a'longitudinal sectional view of the same. Fig. 3 is a similar View, illustrating the operation when an ordinary pin is employed. Fig. 4 is a detail view of the rockshaft. Fig. 5 is a transverse sectional view.

Like letters refer to corresponding parts in the several figures.

Referring to the drawings, A. designates'the draw-head of an ordinary car, havingamouth or recess, B, and an opening, 0, in the top of the same.

D designates a coupling-pin,which is'considerably shorter than the pin ordinarily used for this purpose, and is provided with a circular head, E, near its upper end, said pin passing through the opening 0 and mouth B, and working at its lower end in a longitudinal slot,-F, in the bottom of the draw-head. A conicalshaped hood, G, is secured to the top of. the draw-head, and'projects over and above the opening 0, and a recess, a, is cut in the upper face of the said draw-head, the pin D in operation being forced backward in an inclined chute or passage, H, which connects the opening O'with the rear end of the mouth B.

I designates a lever pivoted in the draw -'head J, of the said draw-head, and the rear arm, i,

working in a recess or cut-away portion, K, of the platform L of the car, an extension, M, of

' said lever projecting downward and acting as a counter-balance for the two arms z '11. Arock-v shaft, N, is'journaled to the under side of the platform L, and is provided with operating handles 0 O, the middle portion of the rockshaft being formed with a stirrup, 1?, which curves or extends in a forward direction.

. The operation of my invention will be readily understood from the foregoing description, taken in connection with theannexed drawings.

When my improved form of pin is employed, the coupling is automaticallyperformedwithout the agency of the leverI, the coupling-link Q striking against the pin D and'forcing it backward in the inclined passage H, the head E of said pin being raised, and as soon as the link has passed the pin the latter drops into the same. Thus it will be seen that I provide an automatic coupling in which no springs are employed, so that there will he no danger of the parts becoming broken or disarranged. The hood G prevents the pin from jumping out, the head E acting as a pivot for the said pinin its movements. To raise the couplinglink the rock-shaft N is operated to allow the stirrupI tobear against the rear arm, i, of the lever and cause the latter to work on its pivots, the forward arm, 2', hearing or pressing downwardly 011 the rear end of link Q, and

thus raising the front end of the same, thelink workingin the grooves formed in the interior of the draw-head on each side. By this means the link may be raised to the height desired when coupling with a car in which the drawhead is arranged higher than ordinarily.

An ordinary coupling-pin may be used with my car-coupling,and in Fig. 3 I have illus trated its use and mode'of operation. It will 5 be seen that the front arm, '5, of the lever I is lowered by means of the rock-shaft G, as before described, and the pin rests upon the front end of arm r, so that when the link is passed into the mouth B of the draw-head it strikes against the lever and forces the arm i upward, thereby permitting the pin to drop in its usual place in the link.

The advantages of my invention are numerous; but they need not be particularlyrecited here.

The ear-coupling is simple, durable, inexpensive, and eflicient. Its operation is automatic and positive, and since there are no springs used there will be less danger of the parts working out of order.

It will be seen that the peculiar shape of the interior of the draw-head,with grooves on each side for the link to rest in, allows the link to work as if it were pivoted at its rear end, the lever bearing against the said rear end of the link and directing the height to which itis desired to raise the link.

Having described my invention, I claim as my own- 1. In a car-coupling, the combination, with the link, of alever, I, pivoted in thedrawhead and formed with two arms, 1713, and a rockshaft, also jonrnaled in the draW-headin the rear of the lever and formed with a stirrup, P, for operating upon one ofthe arms, as set forth.

2. In a car-coupling, the combination ot'the lever pivoted in the draw-head, and provided with means for operating the sa1ne,\vith a pin adapted to rest at its lower end upon said lever, as and for the purposes set forth.

In a car-coupling, the combination of alever pivoted in the draw-head, and provided with means for operating the samegvith a pin resting upon said lever, and an inclined passage, as set forth.

4. In a ear-coupling, the combination, with the draw-head provided with an opening, 0, and a pin having a circular head near the top and fitting in said opening, of an inclined passage in rear of the opening, and a conicalshaped hood, G, extending CV01 the opening partly around the pin, as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signaturein presence of two witnesses.
