proved road-bed; Fig. 2 is an elevational' view, partly in section; Fig. 3 is an enlarged sectional view on the line 33 of Fig. 2; Fig. 4 is a detail view showingtheskeleton work of one of the bed sections; Fig. 5 is a detail view of one of the adjustable clamping heads, showing the same inverted; Fig. 6 is a detail view of one of the metal fibers used as a reinforcing medium for the cement body; and Fig. 7 is a detail view of one of the rail cushions.

. This invention relates to a new and useful improvement in road-beds for railways, the Ob] Ct being to construct the road-bed in sections of concrete, the space between the rall-carriers or ties being occupied by re-, movable blocks which not only tend to make the road-bed dustless, but also provide a water shed to preventv the water in cold weather from freezing in the ground or in the cinder bed in which the concrete ties may be embedded.

The tie element of my improved road-bed is made up of concrete molded'about a skeleton frame, said concrete preferably contain- I ing fibers'of bent wire or other metal forms which arepreferably bent or formed with lateral PIOJQCfilODS at their ends. These curved wires answer as reinforcements in tying the body of the concrete together substantia'lly in the same way that fibers, hair or bristles reinforce plaster.

Bearing lates or chairs are provided at each end 0 the tie or cross bearer for the rails, admstaljleclamping heads being mounted thereonto cooperate with the base flanges of the to hold said rails in po-.

ration; Cushions are also preferably a1"- ranged betweenthe rails and their support-' ingchairs;

In the drawings, 1 indicates railroad rails,

which may be of any suitable cross section.

2 are the cross bearers or tie members of the road-bed, and 3 are the intermediate members. The tie 2 is preferably provided with lateral shoulders 2 for supporting the intermediate members 3, and in laying the road-bed a foundation of ballast, cinders or other appropriate material may be employed, and the ties 2 tamped up in the usual and well known manner. The ballast is preferably built up to the shoulders 2' so as to firmly hold the tie in place. The tie 2 is hollowed out on its underside, as shown 'in Fig. 2, and provided with one or more cross flanges 2", which, in the talnping of the material, become embedded and tend to prevent longitudinal movement of the tie. Theties 2 and the intermediate members 3 are preferably provided with longitudinal grooves or serrations on their upper surfaces, so that rain or water can be conducted ofi' laterally to the side edges of the roadbed. A close joint is preferably made'between the members 2 and 3, and the shoulder 2 may be provided with a groove 2 (see Fig. 3) which will tend to conduct any water falling in the crevice between the parts oii to the side edges of the road-bed. The purpose of thus preserving as far as practicable the ballast or dirt road-bed in a dry condition is to obviate objectionable results which might follow the swelling ofa wet dirt ballast incident to frost or freezing 1n cold weather.

4 indicates a bed plate constituting'a chair for'supporting the rail 1, said'chan' being preferably in the form of a casting and haymg a depression 4 inits upper surface, in which is received the projection 5 on a cushion 5 (see Fig 7). Cushion 5 is preferably of fibrous material and is interposed between the bed-plate 4 and the rail 1 not only for the purpose of deadening sound but also for the purpose of cushioning the rail and thus enabling rolling stock, to travel over my improved road-bed at high speeds. The projection 5 fitting into the recess 4. locks the cushion 5 in position and prevents any movement thereof should the rails cree in service. The bed" plate 4 is also provi ed with ears 4 containing openings for receiving bolts 6. The upper surfaces of these ears are provided with radially disposed ratchet teeth serrations 4, as shown.

7 is a circular clamping member having a serrated boss 7 to cooperate with the serrations 4 above described. This serrated boss is ecoentrically ositioned with respect to the circular head so that said head mayv beadjusted rotatively about the bolt 6 as an axis to engage rail flanges of different widths. When properly ad usted, the head 7 is clamped in position by the bolt 6. A recess 2 is made in the ends of the tie 2 under the ears 4*, so that the nuts 6 which cooperate with the bolts 6 may be slipped in proper position by hand, and the bolts 6 .introduced from the top. The nuts 6 are preferably received in a nut seat on the under-sides of the ears 4, and are thus prevented from being turned when the bolt 6 is screwed home. The object in putting the nut underneath instead of on top is to enable both the bolt and the nut to be removed from the tie and re laced by new bolts or nuts in the event 0 breakage. If the bolt was cast in the ear and could not be removed the wearing of the threads of such inseparably-connected bolt would destroy the usefulness of the entire tie. Again, if it was sought to make the belt removable, in the manner in which the nut may now be removed, the recess 2 would have to be made considerably deeper, which would tend to weaken the tie at this point.

The bed plates 4 have dependingmembers 4 embedded in the concrete of the tie, and cooperating with these dependin members 4 are reinforcing tie rods 8 which extend longitudinally the tie and preferably have their ends hooked or bent as shown in Figs. 2 and 4 so as to provide proper interlock.

In mixing the concrete preparatory to its introduction into the mold, which mold contains the parts to be embedded in the concrete in a manner well known in this art, short pieces of wire 9, preferably curved and having their ends bent as shown in Fig. 6, are introduced into the mass of plastic concrete and thoroughly mixed therewith. These wires of course may be shaped as angles and be of varying cross sections, such as square wire, which may be twisted or formed in any other way to insure a secure fastening in the concrete. These wires are used as reinforcements and act substantially the same as hair or bristles mixed with plaster.

I am aware that minor changes in the con-" struction, arrangement and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
