lo all whom it may concern:

Be it lmownthat I, ORsoN N. lKELLY, a citizen of the United States, residing at Dallas,l .in the'county of Dallas and. State of Texas, have invented certain new and use- 111 Improvements in Railway-Ties, of which the following is a, specification, reference beinghad to the accompanying drawings.

This invention is an lmproved channeled metallic "railway tie combined with wooden blocks for supporting the rails and improved devices for fastening the blocks in the tie and the rails on.the blocks, the in-- ventionconsisting in the construction, combination andarrangement of devices hereinafter described and claimed.

In the accompanying drawings.Figure 1 is partly an elevation and partly a longitudinal sectional view of a railway tie embodying my improvements and showing the same in condection with a pair of -rails supported on the'tie; Fig. 2 is a transverse sectional view of the same; and Figs. 3 and 4: are detailed longitudinal sectional views showing modified forms of my invention.

The tie 1 is made of iron or steel and is channel shaped, comprising a bottom 2 and side walls 8. The tie is provided in its bottom, preferably at a central point, with an opening 1 for draining water from the tie and at opposite sides of, the opening are down-turned anchoring flanges 5 which are integral with the bottom of the tie and are formed by down-turned portions thereof. At the ends of the tie the said walls are cut vertically as at 6 to form portions 7 which are turned downwardly and become embedded in the road bed and serve tofirmly secure the tie against transverse movement on the road bed, the flanges 5 securing the tie against endwise movement. The bottom of the tie is also provided, near its ends, with up-turned fianges 8 which bear against the outer ends of the wooden blocks 9 which support the rails 10 and are placed in the tie. The upper surfaces of the blocks are somewhat above the side walls of the tie. A

' of the blocks help to support the blocks in place on the tie and relieve the bolts 10 of side stress. as will be understood.

The rails, which bear and are supported on the blocks have their base flanges engaged on opposite sides by flanged inwardly extending. projections 11 with which clamps 12 are provided, the said clamps bearing directly on the block and their engaging flanges overhanging and bearing on the base flanges of the rails. These clamps are providedwith central openings'and the blocks are also provided with openings 13 which are coincident with those of the clamps and the lower ends of which are enlarged and countersunk as at 14. Bolts. 15 extend up through the openings in the blocks and clamps and have their heads 16 disposed in counter-sinks 14 and bearing against the upper sides thereof so that the heads of the bolts as well as the shanks of the bolts are entirely out of contact with the tie. Nuts 17 are secured on the upper ends of the bolts and bear on the clamps and secure the latter and, hence, also the rails in place on the blocks.

It will be understood that since the blocks are insulators and project above the side walls of the tie and since the bolts which, in connection wit-hthe clamps, secure the rails on the blocks have their lower portlons embedded in the blocks, and together with the clamps, are thus held by the blocks entirely out of contact with the tie, the rails are completely insulated from the tie as is required when the rails are employedas return conductors in electric block signaling and other signaling systems.

In the modification shown in Fig. 3 the bolts 18, which secure the clamps 19 on the blocks 20, pass through the bottom of the tie as well as through the blocks and the clamps, the heads 21, at the lower ends of the bolts bearing directly against the bot-- tom of the tie. In this form of the invention the bolts not only secure the clamps and hence also the rails on the blocks, but also greatly assist in securing the blocks in and to the tie.

1, In the modification shown in Fig. 4 the rails are secured on the blocks 22 by oppositely inclined screw spikes 28 which are provided with clamping heads 24 that have flanges 25 to bear on the base flanges of the rails. These screw spikes are driven in the blocks and their length is less than the vertical extent of the blocks so that the screw shanks become embedded in the blocks and are entirely out of contact with the tie and hence the rails are completely insulated from the tie.

, Having thus described my invention I claim 1. A metallic railway tie, comprising a channeled body portion with a bottom and upwardly projecting side walls, the bottom being formed intermediate of the ends of the tie with a drain opening and the end walls of said drain opening being turned down to form intermediate anchoring flanges, end portions of the sides being turned downwardly below the bottom to formend anchoring members, and the ends of the bottom intermediate said end anchoring members being turned upwardly substantially at right angles to the bottom, whereby to serve as end braces for insulating blocks.

2. A railway tie of the character described, including a metallic body portion having a bottom and side walls, the end portions of the side Walls being turned down below the bottom to form end anchoring members, and the ends of the bottom between said anchoring members being turned upwardly at right angles to the bottom and lying, between at side walls, and blocks 'mounted in between the side walls and restingfupon the bottom and abutting at their outer ends against the upturned ends of the bottom. a

3. A railway tie of the. character described, comprising a channeled body portion with a bottom and upwardly pro ecting side walls, the bottom being formed mter- 'mediate of the ends of the tie with a drain opening and the end walls of said drain opening being projected downward to form intermediate anchoring flanges, the end portions of the bottom intermediate of said end anchoring members being turned upward,
