IMPROVEMENT |N CAR-COUPLINGS.

Specification forming part of Letters Patent No. 146,408, dia-tad January 13, 1874; application filed August 1G, 1873. l

To all whom it may concern:

Be it known that I, GEORGE DANIEL SPIEL- MAN, of Lancaster, in the county of Fairfield and State of Ohio, have invented a new and Improved "Car-Coupling, of which the following is a specification:

My invention consists of a horizontal bar, arranged transversely to the car in a horizontal slot in the end of the draw-head, and pivoted at its middle to the draw-head, and having a hook on one end to engage the end of a similar bar on the draw-head of the other car to be coupled, having a similar hook,iwhich )ins so that cars with 1n im roved cou )ling 7 b can also be coupled to cars having the ordinary couplings.

Figure l is a horizontal section of the drawbars, and a plan of the coupling bars and hooks, according to my improvement, the section being taken on the line x x of Fig. 2. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is an end elevation of one of the draw-heads; and Fig. 4 is a perspective view of one of the coupling bars and hooks.

A represents the draw-heads; B, the horizontal slots inthe ends; C, the coupling-bars;

D," the hooks; E, the pivots of the said bars; F, the pins for the ordinary links; G, the chains for lifting the coupling-bars; I, ascending and descending walls of the slots B, to

allow the draw-bars to swing vertically to engage and disengage them by the hooks 5 and J, recesses to admit the ordinary links to be coupled by pins F. y

It will he seen that the hook of one bar encounters the end of the other bar not provided with a hook, and rises up on it by the curved end a., while, at the same time, the said end swings down in consequence of the hook at the other end rising on the end of the other bar. VThe inclines I, or rather the widened portions of the slots at the inclines, allow the bars to swing in this manner.

The bars C are made wide and strong inthe middle, where they are pivoted, and extend into the slots far enough to receive the pivots E, behind the ordinary coupling-pins F, and

they are slotted, at F F', suiiiciently for -both of said pivots to allow them to swing upward and down, as needed forengaging and disen= gaging with each other.

The coupling is very strong and durable,

and will couple self-actingly, as well on curves as on straight lines, and will uncouple, in case the cars run off or shift, very much relatively to each other.

I propose to employ a lever to pull up the chain for uncoupling the cars, the lever being pivoted to the cars so that a person standing on the ground can uncouple the cars by pull-
