Be it known that I, ASEEKW. SULLENBERGEB, of Laurel, in the county of Franklin, and State ot Indiana, have invented a. new and useful Improvement in Automatic Car-Couplings; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in whichv Figure 1 is a' perspective view, and

Figure 2 a. vertical longitudinal section.

The same letters are enrployed in both figures tov indicate Athe same parts.

My invention consists in a novel arrangement of parts for supporting the coupling-pin of a railroad-car, until, by the entrance ofthe coupling-link into the draw-head, it acts upon a trigger, by which the lpin is released and permitted to fall through the link, and also in the use of a crank for directing the link into thedraw-head, instead of doing so by hand.

The followingdescription will enable those skilled in the artto construct and operate my improvement. l A is the draw-head as most `commonly seen on rulli-oad-cars. B is the coupling-link, and C the couplingpin, which is inserted in the usual manner, through'tlxe draw-head holding the link when in place. This pin is suspended, by a. chain or cord, from the segment D, which is constructed with a4 groove in the periphery, and is attached to the shaft E.v This shaft has its bearings in the buffers of the cnr, and is turned'by a' crank, F, to raise the link. A trigger, Gr, is pivot-ed at G to the draw-head, and extends downwards into the chamber of the draw-head, immediately behind the coupling-pin. At the top o the trigger is a notched head, over which, as the crank is turned, and with it the segment D, a yoke is passed, which, engaging the notch, lholds the pin suspended,until the link,- entering the draw-head, strikes the lower end of the trigger, and, by throwing the `head in the opposite direction, discngages the yoke H, and permits the pin to full by its own gravity.. In order to avoid exposure todanger, by holding the link in the hand to direct it, the crank I is attached to the buffers. By means of' the winch on the ends, the link may be raised, as the cars approach, upon the crank, and directed Vinto 'the draw-head. l l v What I claim as my invention, and desire to secure byLe'tters Patent, isp In combination with the'shzift E, segment D, and pin C, suspended therefrom, I claim the yoke H and trigger G, for holding thepin suspended in'a. vertical position and droppipg it automatically, on the entrance of the link into the draw-head, substantially as described. I

In testimony whereof, I have signed my name to this specification in the presence oi' two subscribing witnesses.
