AUTOMATIC COUPLING FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 745,794, dated December 1, 1903.

Application filed February '7, 1903, Serial No. 142,412. (No model.)

To (6 whom it may concern: der the hook is a foot of such length and Be it known that 1, WILLIAM ERNEST breadth as to rest on the link 0, as in Fig. 1, CROOK, a subject of the King of Great Britain, to keep the parts when uncoupled in proper residing at Surry Hills, near Sydney, in the positions. Attached to the foot is an arm 70, 5 State of New South Wales, in the Commonwhich passes through the link and in the unwealth of Australia, have invented certain coupled position projects forward, as shown new and useful Improvements in Automatic in Fig. 1. The purpose of this arm, the fore Couplings for Railway-Oars, of which the folend of which, Z, is broadened, as shown, is

Unthrown by the spring a: into the position seen in Fig. 3. As soon as the foot 7' is pushed back, so ceasing to support the fore ends of the pivoted brackets f, the latter swing downwardly till they rest as in Fig. 3,whereby the security of the coupling is increased.

There are various minor features of the construction illustrated which may be departed from while still preserving some essential features of the invention.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In an automatic railway-car coupling, a

pair of links arranged to slide along each other a pivoted hook for each link each having a tail slot or recess, a foot on each hook to be struck by the opposite link, and an arm projecting from each foot, as and for the purposes described.

2. In an automatic railway-car coupling a link, a hook to engage the same a spring-actuated pivoted tumbler to engage the hook to hold it either up or down substantially as and for the purposes described.

3. In an automatic railway-car coupling pivoted brackets having pivoted thereto a hook a tumbler adapted to bear upon the said hook and a link to be engaged by the hook to couple the cars, substantially as described.

4. In an automatic railway-car coupling a pivoted beveled link projecting forward horizontally with a slight amount of vertical play, and having a lug a bracket pivoted thereto and a hook pivoted .to the bracket and arranged to engage the opposite link, substantially as described.

5. In combination in an automatic carcoupling device a pair of links, brackets pivoted to the links, hooks pivoted to the brackets to engage the links, foot portions on the hooks resting on the links and arms extending from the foot portion under the links adapted to contact with the opposite link to operate the device.

6. In combination in an automatic. carcoupling device, a pair of links, brackets pivoted thereon, hooks pivoted to the brackets, said hooks having each a recessed tail portion, a tumbler bearing on the tailpiece of the hook and link connections for releasing said tumbler to nncouple the car and for operating the hook.

7. In combination in an automatic carcoupling device, a pair of links arranged to move along each other, hooks secured above said links and engaging the same to hold them coupled, said hooks being operated by the links.

8. In combination in an automatic carcoupling device, a pair of links, hooks secured above said links and engaging the same to hold them coupled and means for disengaging the hooks from the links to uncouple.

Signed at Sydney this 28th day of November, 1902.
