Application mea Marcha, v1909. serial No. 481,417.

To all 'whom t may concern:

Be it known that I, STANLEY W. LYMAN, a native born citizen ofthe United States, residing at Roberts, in the county of Carbon and State of Montana, have invented new and useful Improvements in Railroad-Rails, of which the following is a specification.

The invention relates to an improvement in railroad rails, and is more particularly directed to a rail lnadeup of a series of sections adapted for assemblage in rail form to provide a practically unbroken structure. y The main object of the present invention is the provision of a railroad vrail madeeup of a series of independent sections severally'l including the tread portion and the base portion, the terminals of the tread sections and of the respective base sections meeting in offset planes to provide a practically unbroken rail. j j

Another object of the invention is the combining with a yrail of the specific structure named of a chair'plate adapted to vembrace and clamp the base sections of the rail together and supportthe same inthe road bed, a rail tie being arranged for coperation with the rails intermediate theterminals of adjacent chair rails at proper gage.

The invention will be described in the following specifcation, reference being had particularly to the accompanying drawings, in which Figure 1 is a side elevation of a rail constructed in accordance with my invention. Fig. 2 is a longitudinal section of the same taken just above the securing bolts. Fig. 3 is a perspective of one inemberof the base. Fig. 4 is a perspective of the coperating member of the base. Fig. 5 isa section on the line 5-5 of Fig. 2. Fig. 6 is a sectional view partly in elevation illustrating the improved rail tie used with the rail structure.

Referring particularly to the accompanying drawings, my improved rail is made lup of three sections, a tread section 1, a tread supporting base section 2 and a tread clamping base section 3, both ofsaid base sections coperating with the tread section to form the completed rail. The tread section is formedto provide the usual bar or tread ortion 4, from which depends a central and ongitudinally extending web 5, the under surface of the tread portion immediately adjacent and on opposite sides of the Web 5 beplates` to maintain the ing formed to provide receiving grooves G, as clearly shown in Fig. 5.

The base of the rail is lmade up of two sections for convenience termed the tread supporting section and the tread clamping section. The tread supporting section 2 is formed to provide a laterally extending base section 7 from which projects an upwardly extending wall 8 formed at the upper end to fit within one Iof the grooves 6 in the tread portion. The wall 8 is designed to abut and snugly fit the relatively outer surface of the vweb -5 being formed below the web with a laterally extending shoulder 9 designed to underlie and directly engage the lower edge of the web projection 5. The shoulder 9 is coextensive in width with the thickness of the web projection, and beyond said shoulder the section 2 is formed with a second shoulder l0 of somewhat less width than the shoulder 9 and projectedat an incline to said shoulder, said shoulder 10 being arranged below the shoulder 9. From the edge of the shoulder 10 the section 2 of the rail base is extended downward at 11 into a plane with the lower surface of the section and preferably at an angle -to said surface, as clearly shown in Fig. 5.

The clamping section 3 of the base is formed V,to provide a lateral base ange 12 vcorresponding to the flange 7 of section 2 and a vertically extending wall 13 designed to t at its upper end within the remaining groove 6 of the tread portion to snugly bear throughout its length against the web projection 5 of saidtread portion. The lower inner surface of the section 3 of the base is formed to engage the shoulder 10 and fit against the inclined surface 1l of the section 2, whereby said parts coperate to cffectively clamp the tread portion between them. In the inner surface of the section 3, at the point approximately corresponding to the relatively lower edgeof the web proj jection 5, the section 3 is formed with a longitudinally extending groove or channel 14.

This groove, when the sections are assembled, is, of course, closed bythe adjacent .surface of the web portion 5 and the sections 2, and is primarily adaptedfor the reception of a bonding wire or for service as a housing for power wires. Each of the sections 2 and 3 are formed in the respective walls 8 and 13 with apertures 15, preferably arranged in a central pair and singly adj acent each end of the section. The outer sur- :tace of section 3, which is the inner section, between the pair of openings 15 is channeled at 16 to receive cross bars 17 of a U-shaped retaining bolt 18 designed to pass through the respective sections and interposed web projection of the tread portion. By the groove and surface adjacent the openings 15 the bolt is more securely held and more readily tightened. The respective sections are assembled in offset relation, that is the ends of one section, as 2, are disposed intermediate the ends of the remaining section, as 3, while the ends of the respective tread portions are arranged intermediate the ends of the respective sections. rIhe respective base sections and tread portions thus break joint throughout the entire length of the track, so that the rail is in effect continuous and is not capable of transverse separation at any one determined point.

It is obvious from the construction described that when desired either of the base sections or tread portions may be removed at will and substituted by others, this construction permitting the convenient renewal of either of said sections when desired and particularly the convenient renewal of the tread portion as the same becomes worn in use.

The rail of the present invention is designed particularly for coperation with a road bed forming the subject matter of a concurrent application, and to particularly adapt this rail for cooperation with such bed I provide a chair plate 19 designed to underlie the respective sections of the base and having inturned edges 2O to clamp over the free edges of the base flanges 7 and 12 of the respective sections 2 and 8. The relatively lower surface of the chair plate is inclined in V-form, as at 21, for use with the road bed described.

In connection with the rail structure described I use a rail tie by which the respective rails are maintained at gage. This rail tie is arranged intermediate the ends of the adjacent sections of the chair plate and is adapted to directly engage the sections 2 an'd 3 of the base member. In detailed structure the rail tie comprises a coupling 22 having a central body 23 of angular contour in section to provide for operating the coupling by a wrench or the like. Sleeves 241 project in opposite directions from the body 23 and are interiorly threaded at 25 for the reception of tubular members 2G to the outer ends of which are fixed blocks-27 having overhanging lips 28 to engage the edges or' one of the sections of the base member.

Mounted within the tubular members 26 are rods 29 arranged to extend through the blocks 27 and terminate beyond the same in inclined projections 30 to coperate with the overhanging lips 28 and to engage the free edge of the section of the base opposing the section engaged by lip 28. The inner ends of the rods 29 are threaded at 31 within a threaded bore 32 formed centrally of the coupling body 23, so that by turning said body the parts may be adjusted to move the rails to or from each other and thereby set the track at desired gage.

A simple means, as a yoke 33, is arranged for connection with the coupling 22 for securing said coupling against independent longitudinal movement relative to the tie or other road bed structure.

The rail structure herein shown provides a sectional rail in which effective clamping of the tread portion is secured in a manner to permit the convenient removal of said tread portion it desired for renewal. Furthermore, the particular chair plate described adapts the rail for coperation with the road bed structure in a manner to prevent lateral displacement of the rail while the tie member maintains the rails at elective gage throughout the length of the track.

Having thus described the invention what is claimed as new, is

1. A sectional rail including a base member made up of two sections, a tread portion arranged to lit between and be engaged by said sections, one of the base sections being formed to entirely underlie and support the tread portion, both of said base sections being formed with cooperating interlocking portions below the tread portion, and a chair plate underlying and clamping the sections together.

2. A sectional rail including a base member made up of two sections, a tread portion arranged to lit between and be engaged by said sections, one of the base sections being formed to entirely underlie and support the tread portion, both of said base sections being formed with cooperating interlocking portions below the tread portion, and a chair plate underlying and clalnping the sections together, the lower surface of said chair plate being inclined in two distinct reversely disposed planes.

In testimony whereof I aliix my signature in presence of two witnesses.
