RAIL ooNsrnuorIoN."

Application filed November This invention relates to certain improvements in rail constructions and itis an'object of the invention to provide a device of this lrind comprising a plurality of SQIQTE." ble parts which, when assembled, providea substantially continuous rail.

Another object of the invention is topro vide a rail construction wherein the web comprises two separable sections and wherein the t ead or ball of the rail is effectively held in applied position when the separable sections of the web are in assembled relation.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved rail construction whereby certain important advantages areatta-ined and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully et forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, whereinF- I Figure 1 is a view in side elevation illustrating a rail construction embodying my invention;

Figure 2 is a view in top plan of the structure as illustrated in Figure" 1;

Figure 3 is a cross sectional view taken through a rail constructed in accordance with an embodiment of my invention;

Figure 4 is a fragmentary view in perspective of a tread or ball section as herein employed;

Figure 5 is a fragmentary view in perspective of one of the web sections as herein disclosed Figure 6 is a fragmentary View in perspective of a second web section.

As disclosed in the accompanying drawings, my improved rail construction comprises a web consisting of two separable sections A and B, said sections being of predetermined length and when in assembly having their ends in staggered relation, as indicated at 1, in Figures 1 and 2.

The section A comprises a base flange 2 and an upstanding web flange 3 at substantially the transverse center thereof, the upper portion of the inner wall of the flange 3 being disposed, as at 1, on a predetermined 7, 1925'. Serial No. 67,606.

incline. toward the outer face of such flange l The section B of the web structure also comprises base flange?) provided at its inner longitudinal margin with an'upstande ing web flange 6, said flange 6 being provided along its inner face with an outstanding head 7. The outer face of the bead 7 is curved or channeled, as at 8, for the purpose of lightening the same and also t0:eflec tively compensate for expansion and contraction incident to temperature changes. The inner face of the flange 6 above the bead 7 is also disposed on an incline, asat toward the outer face of the flange 6.

Vhen the web sections A and B are in assembled relation, the bead 7 overlies the inner marginal portion of the flange 2 ofthe section A and said sections A and By are maintained in desired assembled relation through the instrumentality of the coacting bolts 9 and nuts 10. i

When the sections A and B are in proper assembly, the opposed inclined faces i and 1: of the flanges 3 and 6 together with the up per surface of the bead 7 provide a dovetailed mortise or channel in which is substantially snugly'engaged a. central flange 10 depending from a tread or ball section C whereby said section C is effectively maintained in applied position and thereby completing the desired rail construction. The tread or ball section is of desired length and is arranged so that its ends are staggered, as at 11, with respect to the ends 1 of the web sections A and B. I

The flanges 2 and 5 of the web sections A and B are placed upon the base plates 12 held to, the ties or other supports by the conventional spikes 14. The flanges 2 and 5 are held to the base plates 12 by the spikes 15 disposed through suitable openings 16 in the base plates and engaged with the ties or other supports. I

From the foregoing description it is thought to be obvious that a rail construction constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles .and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim A rail construction comprising two separable web sections, each of said sections comprising a base flange and a web flange, one of said web flanges being positioned in termediate the longitudinal edges of the base flange and the second web flange being posi tioned adjacent the inner marginal portion of the associated base flange, the base flanges of both of the sections being coplanar when the sections are in assembled relation, said second named web flange being provided t-herealong with an inwardly disposed bead overlying the inner marginal portion of the first named base flange, means coacting with the web flanges for maintaining the web sections in assembled relation, the upper portions of the web flanges having their opposed faces inclined downwardly and outwardly and coacting with the upper face of the bead to provide a dovetailed mortise, a tread section having a central depending flange snugly engaged within said mortise, and holding members coacting with the base flanges of the web sections.

In testimony whereof I hereunto affix my signature.

HARRY JOHNSON.
