IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 152.941, dated July 14, 1874; application filed August 18, 1873.

To all whom it may concern:

Be it known that I, JAMES OURRAN, of Binghamton, New York, have invented a Oar-Coupling, of which the following is a specification:

Figure 1 is a perspective view of a platform of a railroad-car having my improvements affixed. Fig. 2 is a bottom view of the same with the lower portion of the draw-bar removed, and Fig. 3 is a detached view of the sliding block employed to hold the couplinglink in proper posit-ion to enter the opposing draw-head.

In the drawings, A represents the platform or end of the car. B is the draw-bar, provided with a flaring-mouthed draw-head, B, as is plainly shown in Fig. 2. G is a sliding block, arranged within the draw head and bar B B. Block G is chambered upon the under side, so

as to form flanges or lips c c, for the purpose of receiving and holding one end of the link, as will be explained. This block is also slotted, as at 0 (see Fig. 3,) to receive the drawpin. D D are levers pivoted to the lower side of the platform at D, Fig. 2. The inner ends of these levers are slotted and engage with a stud, c rising from block 0 through a slot, 1), in the draw-bar B, as shown in dotted lines in Fig. 2. Thus, itwill be seen that by means of levers D D, the block 0 can be thrust forward into the mouth of the draw-head, or can be withdrawn toward the rear of the same. E is a rock-shaft mounted on the front of the platform by means of straps E or other suitable bearings. F is a spring pressing upon shaft E, and serving as a friction-stop to retain the shaft in such position as it is placed by means of the lever G at either end. I usually prcfer to square or flatten that part of the shaft upon which the spring F rests, as at c, Fig. 1. H is an arm secured to rock-shaft E at a point a little one side of the center. Arm H is slotted both vertically and horizontally, as shown in Fig. 1. I is the draw-pin, and I is a link pivoted to the pin, and also connected with the arm H by means of a pivot, 'i, which is confined in the horizontal slot. In practice, I would make one or both of the levers G to extend to the top of the car, so that a brakeman can operate it from the roof.

In operating my improvement, I thrust the block G forward, and place the couplin g-link un der the lips 0, so as to prevent the outer end of the link from dropping too low to enter the opposing draw-head, and then, by means of lever Gr, let the pin I down through said link. The two cars are now brought together, and when the link has entered the opposite drawhead a sufficient distance it is secured by the' its actuating devices in case the draw-bar should be torn from the platform, carrying with it the coupling-pin I.

Having thus described my invention, what I claim is 1. In combination with the rock-shaft E, 1evers G, arm H, pin I, and link I, the frictionstop F, substantially as set forth.

2. In combination with the rock-shaft E, pin I, and link I, the arm H, slotted to receive the link-pivot i, substantially as set forth.

3. The combination of the draw-bar l3, havin g a narrow throat and a mouth with inclined sides, with the sliding block 0 and levers I) D, substantially as set forth.
