RAILWAY-TIE.

, Specification of Letters Patent.

Patented Feb. 29, 191 8.

Application filed December 30, 1914. Serial No. 879,758.

To all whom it may concern Be it known that I, SAMUEL T. lVILsoN, citizen of the United States. residing at Charleston, in the county of Kanawha and State of Vest Virginia, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification.

My invention is designed as an improved combination wood and plastic railway tie.

The objects of the invention'will be manifested as the description proceeds.

In the drawings: Figure 1 is a longitudinal sectional view of a railway tie, partly broken away, illustrating the arrangement of the component parts; Fig. 2 is a top plan view, partly in section, and partly broken away, illustrating further the arrangement of the various parts;iand Fig. 3 is a side elevation, partly broken away, the dotted lines indicating the relative position of certain interior parts.

Like reference numerals denote like parts throughout the several views.

The tie, designated as an entirety by the numeral 1 includes an outer plastic body 2 and an inner frame'or structure 3. The frame 3 is composed of a plurality of parallel or wooden cores 4, dove-tailed at their respective terminals as indicated at 5 and embedded, as shown to'advantage in Figs. 1 and 2 in the concrete body 2. 'Gnarled or barbed spikes 6 are driven into the frame 3, the heads of the various spikes being embedded in the concrete or other plastic composition whereby to act as a retaining means therefor.

It will be noted upon reference to Fig. 2 that the truss beams or cores 4 extend in spaced relation to provide for the arrangementof blocks or abutments 7 therehetween, the several blocks being secured to the cores by any suitable means and disposed in laterally alined series preferably at points adjacent the respective tie ends, and approximately equi-distant from the respective ends. The-several abutments serve as a means whereby the truss beams 4 are fastened together in parallelism and thus maintained. Diagonal brace rods or beams 8 are embedded in the concrete tie to abut respectively the end blocks 7 and the intermediate blocks, the position of the mentioned brace rods or beams being illustrated by the dotted lines in Fig. 3. It will be observed that the brace rods terminate at one end at a point directly beneath that portion of the tie directly supporting the rail. The dove-tailed terminal designated 5 will certainly reinforce the concrete and allow the plastic material to adhere to the core or frame to better advantage.

To strengthen the plastic material, a reinforcing wire mesh strip 9 is embedded therein, the said strip being so situated with respect to the frame as to inclose the latter within its respective four sides. The spikes 6 also extend into the frame from the top and bottom thereof, each spike penetrating the reinforcing strip 9.

An enlargement 10 is formed on the rail engaging face of the tie adjacent each end.

each enlargement being recessed as indicated at 11 to form a seat within which the sup! base flange of the rail and to engage the plate 12: bolts or screw 16 serving as the retaining elements wherebvthe members 15 are held in place. It will be noted upon reference to Fig. 1 that the bolts 16 penetrate, not only the members 15. but the plate 12. the strips 1 1, the filler 13, the upper portion of the plastic body 2, and finally the frame or core 3. By the provision of the recess 11, an effectual brace against bodily lateral movement of the rail supporting means is effected. As a further reinforcement for the body 2, a cast steel grating 17 is mounted on the frame 3, embedded in the plastic material and acts directly as a support for the rail fastening means.

From the foregoing, taken in connection with the accompanying drawings it will be noted that the structural parts of the tie are so situated as to be fully protected under all climatic conditions; that the frame 3, when taken in connection with the spikes 6, plate 17 and the reinforcing strip 9, serves to hold the plastic material or concrete together and in proper place; and that by interposing cushion strips lat between the rail and the tie, a soft bed is provided for the former, and the noise incident to the travel of rolling stock thereon materially reduced.

As a result of test, it has been found that a tie constructed as hercinbefore set forth is practically indestructible and of such a nature as to Warrant its use in View of the minimum cost.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device \Vill necessarily yary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claims.

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

1. In a rail'tie, a frame, a plastic body inclosing the frame, and a plurality of barbed spikes driven into the frame to extend outwardly therefrom, the extended portion of each spike being embedded in the plastic body to serve as a retaining means therefor.

52. In a rail tie, a core,a plastic body inclosing said core, a yielding reinforcing element embedded in said body above and below said core, and a further reinforcing element projecting from said core and engaging said first mentioned element, substantially as described.

In a rail tie, a frame comprising a plurality of longitudinal truss beams, a dovetailed extension formed at the respective terminals of each beam, means maintaining the beams in spaced parallel relation, a plastic body inclosing the frame, and a reinfastening means against forcing element embedded in said plastic body and inclosing the frame.

4. In a railway tie, a plastic body, a frame inclosed Within said body, a plurality of barbed spikes driven into the frame to ex: tend outwardly therefrom, the extended por tion of each spike being embedded in the plastic body to serve as a retaining means therefor a reinforcing plate embedded in the body directly adjacent the rail engaging portion thereof, and support means for the rail fastened to the tie directly over the reinforcing plate, as and for the purpose set forth.

5. In a railway tie, a Wooden frame, a plastic body inclosing the frame, means driven into the frame and embedded in the plastic body to serve as a retaining means for the latter, a reinforcing plate mounted on the frame and embedded inthe body, rail support means mounted on the tie directly over said reinforcing plate, said support means comprising a metal plate directly engageable with the rail, 'a Wooden filler between the plate and the tie and a plurality of felt strips interposed respectively between the plate and the filler and the filler and the tie and means to lock the movement relatively to the tie.

6. I11 a railway tie. a wooden frame comprising a plurality of longitudinally extending parallel sections, each section having a dove-tailed terminal, means connecting the respective frame sections, a plastic body inclosing the frame, and a plurality of spikes driven'into the frame to extend outwardly therefrom, the extended portion of each spike being embedded in the plastic body to serve as a retaining means therefor.

In testimony whereof I affix my signature in presence of two Witnesses.
