' RAILWAY-TIE.

Specification of Letters Patent. Application filed April 18, 1914. Serial No. 832,882;

Patented. July 28, 1914.

To all whom it may concern: I

Be it known that I, JOHN W. CLARK, J r. of Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Railway-Ties; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to railway ties in which the body of the ties is made of metal and the direct supports for the rails are small cushion blocks of wood or like material, thus securing all the advantages of a timber tie with the employment of a small quantity of wood. The advantages are the sound deadening effect and elastic support of the rails; the ability to secure the rails in place with the ordinary spikes and the insulation of the rails so as to render them capable of use in the ordinary signaling systerns employing track circuits.

To this end the invention consists in certain novel details of construction and combinations and arrangements of parts all as will be now described and the particular features of novelty pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of a tie embodying the present invention. Figs. 2, 3 and 4 are similar views showing modified forms of plates for holding the cushion blocks in place.

Similar letters of reference in the several figures indicate the same parts.

The body of the tie is formed of sheet metal bent into substantially trough shape, '5. e., having-vertical sides A andvsubstantially flat bottom A. A tie of this form possesses a certain inherent resiliency whlch will relieve the rolling stock from vibrations incident to a rigid bed, but to increase this effect the rails are not supported directly on the metal portions of the tie but upon cushion blocks B. The blocks are fitted in the trough-like body in proper position toreceive the rails and are of such length as 'will afiord sufficient strength to support the formed by slotting thesides A, as at "a, to form tongues which are turned down over the top of the blocks B, as shown.

Longitudinal movement of'the blocks in the tie body is prevented by plates 0 fitting within the trough-like body at each end of the block and interlocking with the tie. These plates may be of various forms, four of which havebeen illustrated. In Fig. 1 theplate has lateral extensions a slotted as at c and these slotted extensions fit over the sides A of the trough-like body, and in addition are providedwith a tongue or extension 0 at the bottom which is adapted to enter a slot 0 in the flat bottom of the trough-like body. In Fig. 2, the plates are similar to those shown in Fig. 1, having slotted side extensions 0 but the tongue at the bottom is omitted. In Fig. 3, the plates are formed with lateral extensions or wings c fitting in slots 0 in the side walls A, the plate being also provided with a tongue 0 entering a slot 0 in the bottom of the tie. In Fig. 4 the plate is similar to that of'Fig. 3, with extensions 0 but with the bottom tongue omitted.

At the points where the rails rest on the blocks the blocks are of a height to support the rails out of contact with the metal of the tie and in order to avoid the use of blocks of greater thickness than the height of the tie, the side walls of the latter may be cut away, as at b. The provision of the shoulders at the side edges of. the blocks'leaves ample room for the insertion of spikes without contacting with the tie body or plates.

The transverse plates'may be provided with central apertures H for fasteners, such as screws or nails, to retain the plates and blocks in proper relative position. Such simple fastening means may be easily removed when the blocks are to be renewed or reversed when worn on one side. i

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent of the United States, is,-

1. A- railway tie comprising a metal trough-like body, cushion blocks seated in the body and projecting at the top of the body to form rail seats, tongues or extensions on the sides of the tie body adapted to be turned down over the cushionblocks, and transverse holding plates fitting within the trough-like body at each end of the block, and having lateral extensions interlocking with the sides of the trough-like body to prevent relative longitudinal movement of the cushion blocks and body.

2. A railway tie comprising Inetal trough-like body having its sides formed with oppositely disposed vertical slots, cushion blocks seated in the body in proximity to said slots, tongues or extensions formed on the sides of the body adapted to be turned down overthe blocks and transverse holding plates having lateral extensions adapted to enter the slots in the sides of the tie body, whereby the plates Will be interlocked With the sides to prevent relative longitudinal movement of the blocks and body. I

3. A railway tie comprising a metal Copies of this patent may be obtained for five cents each, ;b'y addressing the Washington, D. 0.

plates fitting Within the body of the tie and having lateral slotted extensions adapted to fit over the sides of the body to prevent relative longitudinal movement of the blocks and body.
