To all whom may concern:

Be itknown that I, SHERMAN TAYLOR, a

citizen of the United States, residing at WVymore, in the county of Gage and State of Nebraska, have invented a new and useful Composite Railway-Tie, of which the following is a specification. I i

This invention relates to composite rai1- way ties, one of its objects being to provide a sectional tie made up of reinforced con- .view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of'what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawingsz- Figure 1 is a view partly in elevation and partly in section of a tie embodying the present improvements, rails being shown fastened thereon.

Fig. 2 is a plan view of the structure shown in Fig. 1.

Fig. 3 is a perspective view of one of the reinforcing elements.

Referring to the figures by characters of reference 1 designates opposed like sections made up of concrete, each section being in the form of an elongated block having an intermediate flat bearing surface at the top thereof as indicated at 2 and downwardly diverging upper surfaces 3 and 4 extending to the ends of the section. The bottom of each section is preferably substantially horizontal from the outer end thereof to a point under the bearing surface 2 and then is preferably inclined downwardly and inwardly toward the other end of the section as shown at 5. Embedded within the concrete section is a reinforcing rod 6 which, as shown in Fig. 3, is preferably bent to form an elongated loop 7 the crown p01- tion of which is bent upwardly as at 8 while the ends of the loop merge. into fingers 9 which overhang the loop and have upwardly extending stems the bearing surface 2. These projecting terminals are screw threaded so as to be engaged by nuts 11. Formed within'the inner end of each section 1 is a recess 12 and when the two sections are oppositely disposed with their inner ends close to each other, the recesses 12 are adapted to receive the end portions of a coupling pin 13 formed ofsteel or other suitable material. That portion of the pin between the sections 1 is adapted to be engaged by an eye 14 formed at the lower end of an anchoring rod 15 which extends upwardly to and engages the middle portion of a tie bar 16.

- Resting on each of the bearing surfaces 2 is a rail chair 17. The outer side of each chair has a retaining lug 18 struck upwardly therefrom and bent inwardly so as to lap the outer base flange of a rail R. The threaded ends of the stems 10 are adapted to project through the chair at opposite sides of the lug 18, as shown particularly in Fig. 2, the nuts 11 constituting means for fastening the chair to the tie section. The ends of the bar 16 are so shaped as to lap theinner base flanges of the rails R and this bar is adapted to be fastened to the chairs 1'? by bolts 19. The chairs extend inwardly beyond the inclined surfaces 3 of the sections 1 so that the bolts can be inserted readily into these projecting portions of the chair. It is well known to those skilled in the art that ordinary wooden ties when in use, tend to break at three points. The weight of the load on the tie has a tendency to break the tie at the center and also at points directly under the rail. The first break is due to the tendency of the tie to bend over the ballast under the center thereof as the ballast directly under the rails becomes packed.

10 which project through The breaks under the rails are due to the wear upon the ties at these points and the packing of the road bed under the rails which results in the tie sagging directly under the rails and breaking. One of the objects of the present invention, as before stated, has been to so construct the tie as to avoid these ob ections. The tie has been made of considerable thickness and has been reinforced directly under the rails so that it will resist breakage at these points due to the weight of the loads passing over the tie. Should the tie sag at its ends due to the packing of the road bed thereunder, the sections will be free to shift relative to each other by reason of the steel connection 13 therebetween. At the same time the inner ends of the tie sections will be anchored to the connecting bar 16 by the rod 15 so that the parts will not become displaced to an objectionable extent. Ballast may be placed over the inner portions of the tie sections and also under said sections as ordinarily.

crete sections converging downwardly toward each other, a pin anchored at its ends within the respective sections and constituting a connection therebetween, rail chairs secured upon the respective sections, a tie bar connecting the chairs, and a connection between the tie bar and pin.

3. A railway tie including opposed concrete sections converging downwardly toward each other, a coupling pin anchored at its ends within the respective sections, rail chairs mounted on the sections, reinforcing means embedded within the sections and detachably engaged by the chairs, a tie bar secured to said chairs, and a connection between the tie bar and coupling pin.

4. A railway tie including opposed concrete sections converging downwardly toward each other, a coupling pin anchored at its ends within the respective sections, rail chairs mounted on the sections, reinforcing means embedded within the sections and detachably engaged by the chairs, a tie bar secured to said chairs, and connection between the tie bar and coupling pin, said tie bar constituting rail fastening means.

5. A railway tie including opposed concrete sections converging downwardly toward each other, a pin anchored at its ends within the respective sections and constituting a connection therebetween, rail chairs secured upon the respective sections, and a tie bar connecting the chairs 6. A railway tie including opposed concrete sections converging downwardly toward each other, a coupling pin anchored at its ends within the respective sections,

rail chairs mounted on the sections, reinforcing means embedded within the sections and detachably engaged by the chairs, and a tie bar secured to said chairs.
