HIGHWAY TRACK.

Application inea August 1s, 1921; serial No, iezazaiamf` f To all whom t may concern:

Be it known that I, CLYDE TALBOT EL- nunocn, a citizen ci the United States, and resident of San Francisco, county of San Francisco,'and State of California, have invented a new and useful Highway Track, of which the following is a specification.

rIhe present invention relates to improvements in highway tracks and its object is to provide metal tracks for macadamized or concrete road-beds by means of strong, cheap and light rails inserted in the road-bed. Various forms may be designed for this purpose and I show in the accompanying drawings three different applications of the prin.- ciples involved in my invention, the three different designs, while revolving on the `same principle, being selected to illustrate how the principle can be successfully applied to roads subject to heavy, medium or light traflic.

In the drawing Figure 1'is a perspective view of a single track rail, designed'for heavy traffic, Figure 2 a cross-sectional view of a roadbed having rails designed for medium tralic embedded therein, and Figure 3 an end view of a single track rail designed for light traHic.

Referring to the drawing in detail it will be noted that in the form shown in Figure 1 the top plate 1 of the rail, which is rather light in weight, is supported by the two T bars 2 placed in such a manner that the outer end 3 of the T is flush with the outer edged of the topplate, and the webs 6 of the T, which extend vertically into the concrete, preferably to the depth'indicated in Figure 2, support two'rail portions lying intermediate between the edge and the center of the top plate. The web is provided, at its lower end,

Y with a flanged base 7, which. when embedded in and covered by the concrete, serves as an anchor and firmly engages they T Abar with the concrete and prevents any vertical play. The top plate is secured to the T bars by means of the rivets 8 and short angle irons 9, bolted to the T bar and the top plate, as shown at 11, and secured to the web of the T bar by the bolt 14, are usedA to join two adjoining lengths of rail.

I wish to point out that the lightness of the construction, especially as regards the edge portions of the rails, is a particular feature of my rail and that the supporting Ts give sufficient strength to the structure to Specification of Letters Patent. Patentgd Apr. 25, 1922;

allow the top plate to be of comparatively light weight. A

To further reinforce the structure and make a closer union between the rails and the concrete I provide a plurality of cross bars 16 which penetrate the web and extend transversely through the roadbed and lonc i gitudinal bars 20 secured tothe cross bars, thereby binding rail and roadbed into one solid structure.

from that of Figure 1 only in so far as it is somewhat lighter and designed for roads where the traiic is not so very heavy. v The difference consists in the substitution of the L bars 17 for the T bars, the horizontal portion 18 of the L bar being secured to the outer part of the top plate, and the vertical portion 19 taking the place of the web, an anchoring base 21 being rovided like that in the structure shown in igure 1.

In Figure 3 I show a construction suitable for roads of light traffic. While the general idea embodied in the other structures, that is, the supporting of a rather light plate by preserved, this modification shows the whole rail as consisting yolione inverted channel y I iron, thel web 22 of the channel taking the place of the plate above referred to, and the flanges 23 of the channels taking the place of the supporting webs of Figure 1, the anand the roadbed for combining the same into 100 a' solid structure.

2. In a highway track for a roadbed, two rails running parallel to each other, 1 each comprising a horizontal plate disposed longitudinally of the roadbed, supporting mem- 105 bers placed on edge underneath the edgeportions of the plate and embedded inthe roadbed, transverse metal members extending through the supporting members and the roadbed and longitudinal members crossing 110` The structure shown in Figure 2 differs a means of webs anchored in the concrete, is

the transverse members for binding the rails and the roadbed into one solid structure.

3. ln a highway track for a roadbed, a rail comprising a horizontal plate disposed longitudinally of the roadbed, tWo "i" shaped members placed underneath the edge portions of the plate so that the outer edges are substantially flush, the Webs of the T shaped members being embedded in the roadbed.

4. In a highway track for a roadbed, a rail comprising a horizontal plate disposed longitudinally of the roadbed, two 'l' shaped members placed underneath the edge portions of the plate so that the outer edges are substantially flush, the Webs of the T shaped members being` embedded in the roadbed, and having` lateral flanges at their lower edges for anchoring the same in the roadbed.
