RAILWAY ROAD-BED.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed Marci. 28, 1906. Serial No. 308.400.

To all whom it may concern.-

Be it known that I, LUTHER R. ZOLLINGER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Railway Road- Beds, of which the following is a specification.

This invention contemplates the production of a permanent road-bed for railways subject to heavy traffic, which gradually destroys the constructions now employed and necessitates constant repairs at great expense, accompanied by frequent interference with the handling of trains.

My improved construction consists, essentially, of a solid concrete or other artificialstone bed preferably forming a complete floor under the rails and extending below the frost-line, having iron stringers embedded therein beneath the rails, means for securing and detaching the rails without disturbing the bed, and provisions for taking care of the drainage and carrying signaling apparatus.

In the accompanying drawings, Figure 1 represents a plan view of a section of roadbed made in accordance with my invention. Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1. the line 3 3 of Fig. 1. Fig. 4 is a plan view of a section of a rail with its connections. Fig. 5 is a sectional view taken on the line 5 5 of Fig. 4, and Fig. 6 is a sectional view representing the edge of the bed with the drains therefor.

As shown in the drawings, the bed 1, preferably stiffened by strengthening members 1, rests on the foundation 2 below the frostline and extends as a complete floor beneath the system of tracks formed by the rails 3. Embedded in the concrete beneath the rails are the I-beams 4, which extend parallel to and act as stringers for supporting them, a cushion formed by a layer 5 of any suitable material being placed between the rails and the stringers. To secure the rails in place, so that they can be adjusted and removed without disturbing the bed, sockets 6 are formed in the concrete, with metal coils 7 embedded therein to form threads for engaging the bolts or screws 8, which pass through the clips 9 for securing the rails by engaging the flanges 3, the washers 10 for alining the rails by engaging the flanges, and

Fig. 3 is a sectional view taken on' the flanges 4 of the I-beam for strengthening the structure, the washers preferably being of rectangular form, with the boltholes placed eccentrically therein, so that the positions of the rails can be adjusted in alining by turning such Washers.

The bed is provided with a surface configuration and drains, which permit the water to flow therefrom, longitudinal slopes 11 and transverse slopes 12, leading to drains 13, which discharge into the gutters 14 and thence into the conduits 15, openings 16 being provided in the intermediate stringers to permit the water to pass. Longitudinal conduits 17 are formed in the bed for the passage of wires, rods, or the like necessary for signaling, shifting switches, or such purposes.

As shown in Fig. 5, the I-beam 4 is tilted from the vertical line 18, so that its axis lies in the line 19, making an angle a: therewith, whereby the top of the rail is tilted at a like angle to the horizontal. This angle corresponds to the coning of the car-wheels, and the tilt of the rails provides a broad bearing for the wheels and reduces wear that obtains in the usual constructions.

Having described my invention, I claim 1. A railway road-bed comprising, in combination with a rail, an artificial-stone support extending substantially continuously between and along beneath said rail, and a metal stringer embedded in said stone and extending along the length of the rail, said stringer supporting said rail without the intervention of a cross-tie.

2. A railway road-bed comprising an artificial-stone floor, metal beams embedded in said floor, each beam being provided with a web and a fianged top, and rails extending along and supported by the respective beams, said rails being fixed directly to the flanged tops of the respective beams without the intervention of a cross-tie.

3. A railway road-bed comprising an artificial-stone support, I-beams embedded in said support, rails extending along and supported by said I-beams without the intervention of a cross-tie, and means for securing said rails in said positions said support extending continuously between the rails and along the whole or the greater part of the length thereof.

4. A railway road-bed comprising a continuous artificial-stone support with means therein for engaging a bolt, in combination with a rail, a clip for engaging said rail, a washer having an eccentric hole therein for engaging and adjusting said rail, and a bolt engaging said clip and washer to said bed.

5. A railway road-bed comprising an artificial-stone support provided with a socket having a metal thread set therein, in combination with a rail, a clip for holding said rail, a washer having an eccentric hole therein for engaging and adjusting said rail, and a bolt passing through said clip and washer into en, gagement with the thread in said socket.

6. A railway road-bed comprising a solid artificial-stone base extending along and between the rails, I-beams embedded in said base, rails extending along and supported by said I-beams, and reinforcing members em- LUTHER R; ZOLLINGER.
