JOSEPH CLARK, OF GREEN POINT, NEW YORK.

METALLIC RAILROAD-TI E.

SPECIFICATION forming part of Letters Patent No. 259,095, dated June 6, .1882.

' Appiiatim sled March 16,1882. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH CLARK, of Green Point, in the county of Kings and State of New York, have invented certain new and useful Improvements in lVIetallicRailroad-Ties, of which the following is a specification.

This invention relates to improvements on the metallic railroad-tie for which Letters Patenthave been granted to me, numbered 249,503 and dated November 15, 1881, the improvements being designed with a view to make the tie of cast-steel instead of rolling the parts, so as to render them cheaper; and the invention consists of a cast-metal base-plate and arched bearing-plates supported in seats of the baseplate, the top of the plate being recessed for the rails, which are supported on chairs cast in one piece with the base-plate and secured thereto by clamps.

In the accompanying drawings, Figure 1 represents a top view, Fig. 2 a side view, partly in section on line a: fr, Fig. 1, and Fig. 3 a vertical longitudinal section, of my improved railway-tie. Y

Similar letters of reference represent correspending-parts.

`A represents the base-plate, which is made of cast metal, preferably cast-steel, and provided withlongitudinal Han ges aand strengthening-ribs a.

The arched bearing-plates B are set into seats. of the base-plate A, formedby the longitudinal flanges and ribs a a', andv by short transverse pieces a2, as shown clearly in Fig.

1. -The bearingplates B are recessed at the top to provide space for the base of the rails, which are supported on chairs C, thatare cast in one piece with the base-plate A. The supportingedges of the recessed bearing-plates B are on a level or slightly above the level ofthe top surface of the chairs C, so as to give acertain spring to the' rails in yielding to the pressure thereon. The base of the rail is secured to the chairs by means ofclamps D, the ends of which arelapped over the hase of the rail, as shown clearly in Fig.. 3.

By this construction my improved railroad tie is adapted to be made of cast metal, so that `it can be manufactured at less expense and with greater facility.

Having thus described my invention, reference being had to the accompanying drawings, I claim as new and desire to secure by Letters Patent- The combination of a base-plate having seats or sockets for the bearing-plates and chairs for the rails, cast in one' piece therewith', with arched bearing-plates having top recesses for Ithe rails, and with clamps for attaching the base of the rails to the chairs, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres l ence of two subscribing witnesses.

JOSEPH CLARK.
