IMPROVEMENT IN RAILWAY-TIES.

Speciication forming part of Letters Patent No. 145,258, dated December 2,1873; application tiled September 27, 1873.

To all whom it may concern:

Be it known that I, THEODORE It. TIMBY, of Tarrytown, in the county of Westchester and State of New York, have invented an Improvement in Railway-Ties, of which the following is a specification:

This invention consists in connecting two rail bearings or supports on opposite sides of the track by means of a transverse tie, consisting of a wrought-iron platev placed in a vertical or nearly Vertical plane, and secured to the bearings by casting them upon its ends, as hereinafter described.

In the accompanying drawings, Figure l is a plan view of a rail-tie illustrating my invention. Fig. 2 is an elevation of the same, one end being shown in section on the line t, Figs. l and 3. Fig. 3 shows an elevation of one rail with two of the ties in section-one on the line w and the other on the line w, Fig. 2. Fig. 4 is a perspective view of the wrought-iron tiebar detached. Fig. 5 is a plan view of one of the tie-bearin gs under a slightly modied form. Fig. 6 is a section on the line y y, Fig. 5. Fig. 7 is a plan view illustrating another modification. Fig. Sis a section on the line z z, Fig. 7.

The railbearings B B are preferably made hollow underneath, and with a iianged projec-L tion, C, on top, constituting a seat for the rail A. A web or projection, D, underneath embraces the end of the wrought-iron tie-bar E, holes e e being formed near the ends of the bar E, into which holes the molten metal runs. The body B of the bearing may have a con cavo-convex form, hemispherical on top, as illustrated in Figs. l, 2, and 3, or circular with a iiat top, as shown in Figs. 5 and 6, or angular, as shown in Figs. 7 and 8. The bearing itself is not claimed as new, nor is the inven- Y tion limited to the form of the bearing, which form may be variously modied without departing from the essential principles of the invention. In conscting the device, the tie A bar E of steel or wroughtiron with perforated ends is set on edge, with its ends in molds adapted to form the castings B C D, and the said castings are then frmed by running the molten metal into the molds upon and around the ends of the bar. Each pair of bearings is thus durably and immovably connected. In using the invention, the-ties are laid crosswise of the track, and the rails A, which may be of any common or suitable form, are set inA the principle well known with bearings of this.

general form. The at tie-bar E, being placed in vertical or nearly vertical plane, meets with no considerable vertical resistance from the ground, but cuts into the earth to accommodate itself to the positions ofthe castings B C D, and is thus relieved of vertical strain. The tie-bar is iiexible horizontally, and has thus a further facility of accommodation to the rails. It, at the same time, offers an unyielding resistance to the spreading of the rails. The mode described of casting the bearings on the ends of the tie-bar dispenses with the need of screws, bolts, rivets, or other separate means of attachment, which are costly, and, furthermore, are always liable to become loose. The web D constitutes an anchor to prevent any lateral motion of the rail-bearing B.

The following is claimed as new:

The railway-tie herein described, consisting of a dat bar, E, set in a vertical or nearly vertical plane with bearings B C D cast on its ends, in the manner described. v T. R. TIMBY.
