STEEL TRACK.

Specification of Letters Patent.

Patented Jan. 20, 1920.

Application filed October 16, 1918. Serial No. 258,366.

To all 'whom t may concern.'

Be it known that I, SANFORD B. DICKIN- soN, a citizen of the United States, and a resident of Bath, in the county of Steuben and State of New York, have invented a new and Improved Steel Track, of which the following is a full, clear, and exact description.

This invention relates to railways and particularly to an improved allsteel track and foundation, and has for an object the provision of an improved arrangement whereby a continuous sup vided or separate posts or piers may be provided for supporting a metal track carrying rails of the usual type now in common use.

Another object ofthe invention is to provide an all steel trackv wherein the rails are supported on a resilient bearing member, proper girders are provided and a proper more or less resilient foundation is provided formed in the nature of spaced supporting columns or piers.

A still further object of the invention is to provide a plurality of supporting standards of metal with supporting substantially T-shaped beams connected therewith and formed with a recess for receiving rails of the usual type whereby a continuous support is provided for the rails and spaced supports for the under frame of the entire struct-ure.

In the accompanying drawing:

Figure l is a top plan view of part of a trackdisclosing an embodiment of the invention.

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

Fig. 3 is a transverse section through Fig. 1 on line 3 3.

Fig. 4 is a top plan view ofv a slightly modified structure of that shown in Fig. 1.

Fig.l 5 is a detail fragmentary side view of part of a standard embodying certain features of the invention.

Referring to the accompanying drawing by numerals, 1 indicates the various foundations of concrete or other suitable material which may be any desired depth. These bases or piers are preferably of such width as shown in Fig. 1 to extend an appreciable distance beyond the outer edges of the rails 2 and 3. Instead of building an ordinary ridge of earth or other material on which the ties and rails are placed, it is intended to build a row of piers 1 with the upper portvmay be prosurfaces in a horizontal plane, while the lower end may be an appreciable distance from the general level of the various piers or only a short ldistance therefrom. In arranging a roadway over a morel or less rough country vsome of the pillars would be comparatively short, as for instance three or four feet, while others may be comparatively long or high, as for instance twenty feet. The height of the pillars is immaterial as long as a proper foundation is provided therefor andthe upper surfaces are inv a substantially horizontal plane. A` resilient supporting member is embedded in the upper ysurface of each pier, said resilient' supporting' member being wood, rubber, fiber, or any 'other desired material. On top of this resilient supporting member 4 is arranged a base member 5 having an upstanding web 6 which 'acts as a standard. It will, of course, be understood that there is provided one standard for each pier l, said standard having notches 7 therein as shown in Fig. 5 for 'receiving the truss beams 8. These truss beams may extend across a number of the standards 6 or may extend only from one standard to the other as preferred. In the two illustrations shown in the drawing the various truss beams 8 extend across a number of the standards 6 and are connected at their abutting ends by a substantially U-shaped fitting 9 having iianges 10 and 11. Bolts or rivets extend through the fitting 9 and the respective end portions of the truss beams 8, while bolts 12 extend through the flanges 13 and 14 of the respective beams and the flanges 10 and 11 of the fitting 9. In this way the parts are rigidly connected together at the abutting ends.` In order to connect the various beams 8 to the respective standards 6 an angle iron 15 is positioned at the juncture of the web 6 and the beam 8 as shown in Fig.l l.V These various angle irons are bolted, riveted or otherwise rigidly secured to the web 6 and to the truss beams 8 thus rigidly securing the parts together at this point so as to make a continuous solid structure from one end of the track to the other. In forming the substantially T-shaped truss beams 8 they are provided with a groove 16 in which a cushioning member 17 is positioned and on which the rails are placed. The cushioning member 17 may be made in sections or one continuous strip and is intended to extend for the full length of the track so that the respective rails :2 and 3 will rest thereon continually and be cushioned thereby while both tracks, standards 1 and associate parts will be cushioned by the cushioning member 4 positioned below base of the respective standards 6. In order to Jfasten the rails 2 and Sin place anumber' or fastening plates 18 are provided on each side oi the rails, said fastening plates being held in place by suitable bolts 19 which bolts extend through the iti-anges 13 and 141 of the truss beams 8. These fastening plates ot' course oi'ferlap the base ofthe rails and press against the same continually as shown in Fig.

In Fig. et a slightly modified forni of the invention is shown in which the fastening plates 1S are not short small plates as shown in Fig. 1, but are continuous strips extending for the r'ull length or" the rails; These plates 18 are held in place by any desired number of bolts 19 arranged at intervals along the various strips; vThis arrangement of strips acting as 'fastenin plates is desirable for extremely heavy tra lic, though for' ordinary trafic the short stripsv are preferable.

What I claim is:

1. A railway, comprising a series'ot supyerted T-shape in porting piers, having cushioning members embedded in their upper faces, transversely positioned standards having their base portions supported on the cushioning members, trusses secured on the standards, and rails secured on the trusses.

2. A railway, comprising a seriesy of supporting piers, having recesses in their upper ends, cushioning members in the recesses, transversely positioned standards of incross-section, having' their base portions in the recesses and supported on the cushioning members, longitudinal trusses supported on and secured to the standardsand rails on the trusses.

3L A railway, comprising a series of supporting piers, having recesses in their upper faces, cushioning members in the recesses,

transverse standards of inverted T-shape in' cross-section, supported on the cushioning members, said standards having notches in their upper edges,- T-shaped trusses secured in said notches and having longitudinal grooves in their upper faces, cushioning material in said grooves', and rails secured to the trusses and supported on said last-mentionedcushioning material.
