COUPLING.
SPECIFICATION forming art of Letters Patent No. 755,652, dated March 29, 1904.
Application filed April 2, 1903. Serial No. 150,768. (No model.) I
To all whom it may concern:
Be it known that I, DAVID GREENBURY, a subject of the King of the United Kingdom of Great Britain and Ireland, and a resident'of Morayfield, in the State of Queensland, Commonwealth of Australia, have invented certain new and useful Improvements in Automatic Couplings for RallwayWagons and Carriages,
of releasing-link; Fig. 3, an end view ofcoupling-hook and releasing-link and couplinglink; Fig. 4, a plan of coupling hooks and links with wagons coupled together; Fig. 5, a side elevation of wagons coupled together. Fig. 6 shows coupling thrown out of action; Fig. 7, an end View of wagon, showing chains connecting to releasing-links.
The reference-letters indicate like parts in all figures.
A is a draw-bar pivoted to cross-tie on underframe of wagon, as shown in Figs. 4 and 5, and provided with spring at end thereof connected near the shoulder by tie-rod B to bogie of wagon, which controls the position of the draw-bar and insures the meeting of the drawbar with the opposite link when coupling on a curve. Forming an integral part of the draw-bar are ears A, between which is secured by bolt and nut coupling-link C, the link pivoting on the bolt. Also forming an integral part of the draw-bar is a hook A with sloping end, acting as an inclined plane for the coupling-link on end of other draw-bar.
To the end of the coupling-hook A is pivoted a releasing-link D, attached to which is a chain E, leading through a staple F onside of coupling-hook, thence branched and carried over pulleys on end of wagon to the sides thereof, and at the end of each branch of the chain is a ring E, which on uncoupling the 'fall over, the releasing-link D is drawn forward by the weight of the coupling-link, and
the wagons or carriages are automatically coupled together. To uncouple, the chain E is pulled down from either side of the Wagon or carriage, when the releasing-link D draws the coupling-link from the end of the hook, allowing it to slide up the inclined plane formed by the link D when the coupling-link disengages itself from the hook.
To hold the parts in position to preventcoupling, one ring E is engaged with its hook G; but it may be afterward disengaged by turning the rod H, which can be done from either side of the carriage.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In improvements in automatic couplings for railway wagons or carriages, a draw-bar having a pair of ears and an extended end forming a hook, in combination with a coupling-link pivoted between the ears, and a releasing-link pivoted to the hook, as and for the purpose set forth.
2. A draw-bar having a hook, a releasinglink pivoted thereto, a chainleading from said link and branched to either side of the railway-carriage, and a ring at the end ofeach branch; in combination with a rod journaled across the carriage, and hooks secured thereto in parallelism near its extremities, as and for the purpose set forth.
3. A draw-bar having short cars at one side and a long hook at the other, a coupling-link pivoted to the ears, and a releasing-link pivoted to the hook and adapted to swing across I simultaneously from either side of the car- IO its throat to disengage the companion coupriage, as and for the purpose set forth. ling-link therefrom; in combination With a In Witness whereof I have hereunto set my chain leading from the lower pogti? of thg hand in presence of tWo Witnesses.

ends of the branches, retaining-hooks for said R. A. MOORE,
