DRAFT-IRON FOR CAR-COUPLINGS.

SPECIFICATION formingpart of Letters Patent No. 530,211, dated December 4 1894.

Application filed February 23,1894. Serial No. 501,226- (No model.) I

T0 on whom it may concern.-

Be it known that I, JAMES TIMMs, of Co lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Draft-Irons for Car- Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in draft irons for car couplings, and it consists in a fiat plate of metal having upwardly extend- 1ng lips adapted to be let into the lower surface of a draft timber of the car to which the 1I'0I1 is attached, said plate provided with strengtheningribs at the edges, a web extending between these longitudinal side ribs and forming a slot for the ends of the followers and ribs 71. forward and rearwardof and integral with the web whereby the latter is strengthened where the greatest strain comes.

In the accompanying drawings Figure 1 is a view in side elevation showing the draft timber of a car, the draft iron and a draw bar or coupling. Fig. 2 is a perspective view of the iron, and Fig. 3 is a view in longitudinal section through the draft iron.

A represents the draft timber of a car and B the draft iron secured to the under side of the timber by the bolts C. There are two of these irons to each coupling, each iron being secured to the under side of its draft timber and separated sufficiently for the reception of the spring D between them. As both irons irezhalike, a description of one will suffice for Each iron B is made of malleable cast iron, itsupper face a being fiat so as to rest solidly against the under side of the draft timber A, the extreme ends of the irons being turned upwardly forming lips d which latter rest in grooves 6 formed in theunder side of the timber A, and materially assist the bolts C in resisting the end strain. Each iron 13 is enlarged centrally and is provided with a horizontal slot f which latter receives one end of the follower F. This slot is of length sufficient to permit of the necessary longitudinal movements of the coupling, and the end walls and bottom thereof are strengthened by the ribs 72. located at the sides and extending from one end of the iron to the other, and by ribs h located centrally between ribs h.

The irons are secured to the under side of the draft timbers A by bolts C which latter pass through bolt holes formed near the opposite ends of the iron between the ribs h.

The ends of follower F rest in the slots in the irons behind the spring D while the follower F is also supported at its'ends in said slots in front of spring D.

The coupling G is suitably supported in 'a plane between the two irons with its rear end in contact with the follower F, and is connected to the rear follower F by the tail bolt H which latter is secured by head 11 to the rear end of the coupling and passes through follower F and F, a keyj being employed behind the follower F to lock the tail bolt in place. If only only one spring D is employed the tail bolt will pass centrally through same but if two are employed the springs will rest on opposite sides of the tail bolt.

From the foregoing it will be seen that as the coupling is drawn out, the follower F will move toward the front of the car compressing the spring D against follower F, and as the coupling is forced inwardly, the' follower F willbe moved rearwardly compressing spring D against follower F. The draft irons formed of malleable metal cast in one piece with the ribs and tips is stronger, will stand greater strain than the wrought metal iron, and can be produced at less cost than the irons commonly used.

It is evident that many slight changes and alterations might be resorted to in the relative arrangement of parts herein shown and described without departing from the spirit and scope of my invention. HenceI would have it understood that I do not wish to limit myself to the exact construction herein shown, but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A draft iron for car couplings constructed and adapted to be attachedto the lower face of a draft timber and comprising a flatplate of metal having upwardly turned lips adapted In testimony whereof I have signed this specification 1n the presence of two subscrib- IO mg witnesses.

JAMES TIMMS.
