METALLIC RAILWAY-TIE.

Specification of Letters Patent.

Patented Feb. 3, 1914.

Application filed September 19, 1912. Serial No. 721,284.

To all whom it may concern Be it known that I, WILLIAM T. Co a citizen of the United States, residing at San Bernardino, in the county of San Bernardino, in the State of California, have invented new and useful Improvements in Metallic Railway-Ties, of which the following is a specification.

My invention relates to metallic railway ties.

One object of my invention is to provide a tie of this type which will effectively remain in place upon the rail bed and secure the rails in line and against spreading.

Another object of my invention is to provide a type of tie wherein the rails will be held against movement so as to overcome the shearing or cutting off of bolt heads used to secure the rails to the tie.

A further object of my invention is to provide means whereby shock and vibration will be absorbed or taken up by the tie, as a train passes along the track, whereby the tie will not rise from its bed or rebound after the passage of a train over the rails supported by the tie.

Another object of my invention is to provide projecting ground engaging means to prevent displacement of the tie when the road bed is in a soft condition.

Other objects will hereinafter appear as the description of the invention progresses, reference being had to the accompanying drawings, wherein Figure 1 is a plan view illustrating a plurality of the ties and rails broken away, supported thereon. Fig. 2 is a view of my improved tie, partly in elevation and partly in section, showing rails clamped in place, and, Fig. 3 is a view partly in elevation and partly in section, illustrating my improved fastening bolt for the rail.

Referring to the drawings, 1 designates a metal railway tie, preferably steel, which is provided on its'upper or top surface with a cavity in which may be placed a suitable vibration-absorbing medium designated 2, for which medium I have found tar paper to be satisfactory.

The usual rails designated 3 are supported upon the upper face of the tie and directly over the vibration-absorbing medium. Below said medium are provided posts or relatively heavy portions 4, which at their base terminate in points or projections 5.

The body of the tie is substantially open. Upper and lower webs 6 connect and distance the posts 4 and from the other sides of the posts 4, project upper and lower webs respectively designated 7 and 8, which upper webs are curved as shown, and join the webs 8 at the ends of the tie. At each end of the tie is provided a projection such as 9. The webs 7 at their inner ends terminate in flanges 10 adapted to extend over the base web of a rail on one side of the central vertical web thereof, as shown. A short distance away from the flanges 10 are provided in the web 6, one or more openings 11 through which are adapted to be passed fastening bolts 12, shown in detail in Fig. 3. Said bolt is provided with a projecting head 13 adapted to engage the base flange of a rail on the opposite side to that of the flange 10. Said bolt 12 has a screw-threaded shank 14 which is suitably recessed to house nut locking arms 15, completely therein. Each arm is pivoted upon a transverse pin 16 and between the arms 15 is supported in any suitable manner, a V-shaped spring 17 which tends to project the arms 15 beyond the exterior of the shank.

The numeral 18 designates a nut adapted to ride upon the screw threads of the shank 14. As best shown in Fig. 2, the posts or thick portions 4 are suitably cut away so as to provide a shoulder 19 adapted to be engaged by the nut 18.

In securing the rail in place the bolt is first inserted through its opening 11, the arms 15 being forced inwardly by the passage of the bolt through the opening. After such insertion in the opening has been effected, the nut 18 is screwed upon the shank 14 and in its movement bears against the arms 15 forcing the same inward. When said nut has passed the arms 15,.the spring 17 forces the arms outward to the position shown in Fig. 3 whereby the nut will be locked. In locked position the nut 18 bears against the shoulder 19, as is shown in Fig. 2.

It will be seen that I have provided a tie having heavy and durable posts or the equivalent, for supporting the rails thereon, and that I have provided relatively thin webs in connection with the posts to provide a substantially open structure. This structure enables the tie to absorb shocks and vibrations so as not to rise from its bed or rebound after the passage of a train thereover.

The projecting teeth 5 and 9 assist in holding the tie in position upon the road bed and are especially useful when the bed is soft, as is the case after a rain.

It is to be understood that the preferred embodiment of my invention has been described and shown herein, and that changes in the details of construction may be made within the spirit and scope of the appended claims.

Having thus described my said invention, what I claim and desire to secure by Letters Patent is:

1. In a metallic railway tie forming an integral structure a substantially open body, posts to support rails, upper and lower webs extending from said posts, said upper webs being curved and joining the lower webs.

2. In a metallic railway tie, posts, webs spaced apart and connecting said posts integral therewith, spaced-apart webs extending from each post, said latter webs being formed integral with the post and the upper web deflected downwardly and joining the lower web and provided with a rail engaging projection located adjacent said posts, and rail fastening means separate from said posts.

3. In a metallic railway tie, post-s, connecting means therefor, upper and lower webs integral with said posts and extending therefrom, the upper webs provided with rail-engaging projections, being connected to the lower webs and terminating in ground-engaging projections.

4. A metallic railway tie, posts, connecting means therefor, upper and lower webs formed integral with said posts and extending therefrom, the upper webs provided with rail engaging projections, being connected to the lower webs and terminating in ground engaging projections, cavities formed in said upper web beneath the rail engaging portion of said web for the retention of suitable vibration-absorbing means.

5. In a metallic railway tie, posts, webs spaced apart and connecting said posts integral therewith, spaced apart webs extend ing from each post, said latter webs being formed integ-al with the posts and the upper web deflected downwardly and joining the lower web and provided with a rail engaging portion adjacent said posts, ground engaging projections formed on the outer extremities of said latter web, and ground engaging projections formed on said lower web beneath and in alinement with a portion of the upper web upon which the rail is seated, cavities formed in said upper web beneath the rail engaging portion of said web for the retention of suitable vibrationabsorbing means.
