CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 228,469, dated. June 8, 1880.

Application filed January '7, 1880.

To all whom it may concern Be it known that I, ELI H. MOORMAN, of Walnut township, in the county of Madison and State of Iowa, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being made to the accompanying drawings, forming a part of this specification, and in which- Figure 1 represents a front view of my im proved coupling; Fig. 2, a central longitudinal vertical section of the same; Fig. 3, a bottom-plan view; Fig. 4, a top view with the platform of the car removed.

My invention relates to certain new and useful improvements in the class of car-couplings adapted to be automatically coupled and uncoupled without a person going between the cars; and to this end the invention consists in the novel construction, combination, and arrangement of parts, all as will be hereinafter fully described, and specifically pointed out in the claims.

In the drawings, A represents a movable bumper, adapted to work in a groove formed in the top of the main body of the coupler, and projecting over the rear end thereof on each side, and having notches N N, to receive the connecting-arms D D of a double lever, B, said bumper being held in position by a staple, a, near its rear end.

The lever B passes around the front end of the coupler, and is pivoted thereto at the point I), the arms I) of said lever passing along the sides of the body of the coupler, and connected at their rear ends by a pivoted crossbar, I, to which is connected the rear end of a lever, O, carrying at its forward end the coupling pin X, having an enlarged head working loosely in a slot formed in the forward end of the lever 0, said pin passing up through the coupler from the bottom.

E represents a link-adjuster passing transversely through an opening in the coupler just back of the pin X, and the arms of said link-adjuster are pivoted to the sides of the coupler and provided with lugs or projections c, resting on top of the arms of the lever B, in

front of the connecting-arms D D of said lever. The link-adjuster ishollowed out on the under side to receive the coupling-link.

K represents a chain, connected at one end near the rear end of the buffer A, passing forward and under a pulley, R, set in the frame-work of the car, and connected to a right-angled lever, L, pivoted to the car, as shown in Figs. 1 and 2.

The car is uncoupled by drawing the bumper or buffer A outward through the medium of the lever and chain, which movement, through the medium of the connecting-arms D D, raising the rear end of the levers B 0, causes the link-adjuster to be raised off the link and the pin X to be drawn down out of the coupler, thus releasing the coupling-link.

The cars are automatically connected by the bumper being forced back by a bumper on the next car coming in contact therewith, thus producing a reverse movement of the levers B O, forcing the adjusting-link down on the coupling-link and the coupling-pin up through it.

In case of the cars running off of the track or accidentally breaking or dropping througha bridge, the coupling-link will become cramped upon the front end of lever B by the weight of the car, which will raise the rear end of the levers B O,'thus drawing out the coupling-pin, and uncouple the falling car; but said lever B will resist all pressure from the coupling-link when the-cars are running on the track.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a car-coupling, the combination, with the movable bumper A, of the pivoted double lever B, provided with the upwardly-projectin g arms D D, and the pivoted lever C, carrying a coupling-pin adapted to enter the coupling-link from below, substantially as herein shown and described.

2. In a car-coupler, the combination, with the movable bumper A, of the pivoted double lever B, having the projecting arms D D, and the link-adjuster E, pivoted to the sides of the coupling-bar, and having its arms pro+ vided with projections e, resting" on the arms of the lever 13, substantially as and for the purpose herein shown and described.

3. In a car-coupler, the combination of the movable and notched bumper A, pivoted dorr ble lever B, having the arms I) D, and pivoted lever O, carrying the coupling-pin X, pivoted link-adjuster E, chain K, and lever L, all constructed and relatively arranged to operate substantially in the manner herein shown and 10 described.
