CAR-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 475,707, dated May 24, 1892.

Application filed February 24. 1892. Serial No. 422,666. (No model.

To all whom 212': may concern:

Be it known that we, MATTHEW T. SCOTT and J AMES L. BRASFIELD, citizens of the United States, residing at Blue Springs, in the county of Jackson and State of Missouri, have invented a new and useful Oar-Coupling, of which the following is a specification.

The invention relates to improvements in car-couplings.

The object of the present invention is to provide a simple and ineXpensivecar-coupling, which will couple automatically, and which may be readily uncoupled from the top of a car without injury to the operator by passing between the cars, and which may be readily raised to couple with the ordinary pinand-link coupling.

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 a perspective view of a car-coupling constructed in accordance with this invention. Fig.2 is a horizontal sectional view. Fig. 3 is a plan view illustrating the coupler arranged to receive a pin and a link. Fig. 4 is a detail perspective of the pin-and-link attachment.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates the draw-head, having a stationary jaw 2 arranged at one side and provided at its other side with a spring-jaw 3, and having a space between the jaws adapted for the reception of the stationary jaw of a twin coupling. The stationary jaw is shouldered at its outer side and has its outer end beveled slightly on both faces, and itis adapted to be engaged by the spring-j aw 3 of a twin coupling. The spring-jaw 3 is shouldered on its inner face, and it is adapted to engage the stationary jaw of another coupling.

The cars are uncoupled by a vertical shaft 4., which is j ournaled in suitable bearings on a car 5. It is provided at its upper end with an ordinary hand-wheel 6, and it has its lower end connected to chains 7 and 8, which are connected, respectively, with the on ter end of the spring-j aw 3 and with a lever 9, arranged in the groove 10 of the stationary jaw 2. The lever 9 is fulcrumed intermediate its ends. It is arranged longitudinally on the stationary jaw at the outer face thereof and its outer end extends beyond the shoulder of the staside of the car, and when the shaft is turned to wind the chain around it the spring-j aw will be drawn away from the stationary one and the outer end of the lever will be thrown out Ward laterally. The pulley 13 is arranged in a suitable bracket 14. and enables the lateral pull upon the spring-jaw to be more direct. The jaws may be held against coupling by a pawl 15 and a ratcheewheel 16, arranged on the top of the car. The rod 12 is arranged in a transverse opening of the draw-head, and the chain 7 is provided with a turn-buckle take-up 17 to increase or diminish the length of the chain 7 to equalize the chains, whereby the proper pull on the spring-j aw and the uncoupling-lever may be obtained.

WVhen it is desired to couple the car 5 with a car having the ordinary pin-and-link coupling, a pin-and-link attachment 18 is fitted on the draw-head and is provided with the ordinary link-cavity 19 and a coupling-pin perforation 20. The pin-and-link attachment is provided with a longitudinal slot 2l,whichis adapted to receive the stationary jaw and which conforms to the configuration of the same, and its side 22 is recessed and shaped 0 that it may be readily uncoupled from the top of a car. By means of this ready coupling and uncoupling trains may be made up in much less time than bythe ordinary coupling.

What is claimed is 1. In a car-coupling, the combination of a draw-head havinga stationary jaw at one side, a spring-jaw arranged at the other side, a lever arranged on the stationary jaw, and means for moving the lever and the spring-j aw laterally, whereby cars may be uncoupled, substantially as described.

2. In a car-coupling, the combination of a draw-head having astationary jaw at one side shouldered on its outer face and provided with a longitudinal groove, a lever arranged in the groove and fulcrumed on the stationary jaw, a spring-jaw arranged at the other side of the draw-head and shouldered on its inner face, a shaft, and chains connected with the our own we have hereto affixed our signatures in the presence of two Witnesses.
