D RAW-BAR FOR RAI LWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 232,152, dated September 14, 1880.

Application tiled .Tilly 2G, 1880.

To all whom it may concern:

Beit known that l, WILLIAM H. STACK- HOUSE, of Berwick, in the county of Columbia and State of Pennsylvania, haveinvented certain new and useful Improven'ients in Dra-w- Bars for Railway-Cars; aml I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to inake and use the same, reference being had to the accompanying drawings, and to the letters and figures ot' reference marked thereon, which form a part ot' this specication.

The saine letters and figures of reference are used to indicate the corresponding parts.

After describing the invention, its nature and extent `will be shown in the claims.

The object of my invention is to provide a continuous draw -bar with a single central spring, which shall divide the tensile strain between the central and the' more dist-ant .springs Figure l is an inverted plan View of my i11- Fig. 2 is a vertical sectional view taken through the line m of Fig. l.

A A are two center' stringcrs ofthe car-bed. B B are the end sills, to which the center stringers are attached. D D are the drawheads. E is the continuous d raw-bar, to either end of which is attached the draw-head I). G Gare the draw-head planks, which 'are attached to the under side of the stringers A A. F F are rigid plates iirnily fastened in the draw-head planks. Between these plates and the draw-heads are placed the springs a c, which are coiled around the draw-bar E, and are thus held in position.

I) b are two movable follower-plates in the (No model.)

center of the drawbar. Between these two plates is the helical spring` c, coiled around the draw-bar. The plates b b are kept in position by the keys d d, which pass th rough the draw-bar E.

H H are keepers, within which the followers b b move backward or forward.

It is evident that the tensile strain on either draw-liead will Ue divided between the central spring and the spring at the opposite end ot' the draw-bar.

I am aware that two drawbars, with a spring at either end of each, have been used in connection with a rectangular framework in the central part of the car-bed.

My invention is both simpler and cheaper, and therefore more desirable and useful, than a draw-har made in this manner.

Having now described my invention, what I claim, and desire 'to secure by Letters Patent, s-

l. In a draw-bar for railway-cars, the central helical spring, c, surrounding the draw-bar, the followers b b, the keys d d, a-nd the keepers H H, substantially as shown and described, and for the purposes herein set forth.

2. The central spring, c, thefollowers b I), and the draw-bar E, in combination with the springs a a and the draw-heads D D, substantially as shown and described, and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 22d day ot' July, 1880.

WILLIAM H. STACKHOUSE.
