AM PHOTOiITHOG/MPHIL' ca My (assent-Is man-55s) UNITED STATES WILLIAM BEMAN, OF PORTLAND, MAINE, ASSIGNOR or TWO-THIRDS HIS RIGHT TO MIOAH SAMPSON, or SAME PLACE.

IMPROVEMENT m CAR-COUPLINGS.

To all whom it may concern:

Be it known that I, WILLIAM E. BEMAN, of Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Oar-Couplings; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, which is hereby made a part of this specification, in which Figure l is a bottom-plan view of my device. Fig. 2 is a side sectional elevation upon the line at a. Fig. 3 is a front-end view of same.

Same letters show like parts.

My invention relates to certain improvements in devices for coupling railway cars or carriages, whereby the function of coupling will be performed automatically, thus effecting a great saving of time and immunity from danger for theoperator. My invention consists of certain devices for changing the drawbars of a car to different heights, so that they a correspond in height to the draw-bars of cals to which they are to be coupled.

U1 erneath a draw-bar of any ordinary construct n I place the cross-bar 'i, firmly attached by the hangers j and Into the body of the car. Around this cross-bar I coil the involnte springt, the ofite end of which presses against the draw-bar and forces it upward against the lever m, the draw-head being so affixed to the plate a as to permit of its vibration vertically, in a manner to be hereinafter described. The lever m is pivoted at o and passes over the draw-bar outward to any convenient length to be operated by the hand of the workman. The ratchet p is so arranged that the lever may be caught at as many different heights as there are teeth in the ratchet, and as the lever presses the draw-head down also, and when the draw-head is relieved from the pressure of the lever on the draw-head rises by the pressure of the involnte spring I, so, as will be seen, the draw-head may be fixed at different heights, as desired.

The lesser chamber receives the end of the link and sustains it horizontally, so that it will readily enter the chamber of the opposite draw-bar.

What I claim as my invention, and desire to secure by Letters Patent, is-

The' combination of the draw-bar, lever m,

spring I, and stirrup-irons j and Jr,-

ratchet 1), all in the manner and for the purposes as set forth. 7
