` c'oNPosrrroN ROAD-BED.

, and chea-penedv construction of reinforced concrete bed' provided with cavities or depressions to receive the rail-supporting devices and also a centrally disposed trough for the reception of water.

It has fora further objectA to provide a concrete base upon which the rail chairs or lfastening devices are supported.l

Other objects and advantages. of the invention will' hereinafter appear and the novel' features thereof will be particularly l pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, -with the numerals of reference marked thereomform a' part of 'this specification, and in which- Figure 1 is a perspective view of the invention with parts in section and portions broken away showing an improved road bed and rails-mounted thereon. Fig. 2 is a vertical transverse section through Fig. 1. Fig.

A3 is a perspective view of one of the chair supporting bases. Fig. 4 is a perspective view of one of the base-supporting springs. Like numerals of reference indicate like parts throughout the several views. In carrying out my invention, I form a base 1 of cement or analogous material suit-- ably reinforced by meta-l reinforcing members 2, as seen in Figs. 1 and 2. The roadbed 1 is formed with cavities or chambers or depressions 3, above which the rails are (le-- signed to be supported, and with an intermediate portion 4 for the reception of water for the usual purpose.

5 are the rails. These are supported upon the rail-supporting bases 6 which are formed of cement or analogous material having the roughened or serrated portions 7 near each end upon the upper face, the intermediate portion being preferably left smooth, as shown at 8. Through each of the Specification of Letters Patent.

serrated portions is formed a'vertical openmg 9 for the reception of the bolts, as seen in Fig. 3. This rail-supporting base has the central body portion 10 which is designed to lit quite snugly within the recess or chamber 3 in the roadbed, as. seen. in Fig, 2, leaving the surrounding horizontal fla-nge 11, as Seen in Figs. l, 2 and 3, whichoverlap's the up- -per faceof the roadbed, as seen `in Figs.

l and '2.

l2l 1s' a spring of preferably the form shown in'Fig. 4. It has its -ends curled upwardly, as seen at 13, and its top portion is provided with openings 14 for the passage of the bolts.

In practice, the springs are placed within` the chambers or cavities 3 in the roadbed, as

seen in Figs. 1 and 2, the bolts 15 having been first disposed-with their heads 16 embedded in the cement or similar material of which the base is formed, as seen clearly in Fig., 2, the openings 14 in the' upperportion of thespring being slipped over the bolts. The rail-'supporting base 6 is then placed in position, the bolts dpassing.through the openings 9 thereofan the body portion of'the rail-sup orting base rests upon the sprlngf The rai -fastening devices 17 are then applied over the bolts and the nuts 18 applied after properly adjusting the fastening de- As will lbe seen in Fig. 2,' the fastening devices 17 are provided with clon'- gated slots 19 so as to permit of proper adjustment of the rail-fastening devices. The rail-fastening devices areA serrated or roughened on their under surfaces, as shown at 20,

for coperation with the .roughenedor serrated surfaces 7 of the rail-su Y porting base 6. 'The springs 12 are of suc tension as to normally hold the rail-supporting bases with their flanges 11 somewhat above the upper face of the roadbed, as seen in Fig. 2, so as to permit of the necessary elastlcity and yielding when the weight of the train is upon the rails, the springs returning the s upporting-bases to thelr normal ositions after the train has passed. The un er face of the fiange 11 coming in contact with the upper face of the roa-dbed serves to limit the down- 'ward movement of the rail-supporting base and the. ends of the spring will contact with` the adjacent walls ofthe chamber 3 to limit the downward movement of the spring.

Modifications in detail may be resorted to invention or sacrificing any of; its advantages. y.
