CARL R. BOWEN, OF FORDYOE, ARKANSAS. v

RAILROAD CONSTRUCTION.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed June 25, 1907. Serial No. 380.686.

To all whom it may concern:

Be it known that I, CARL R. BOWEN, a citizen of the United States, residing at Fordyce, in the county of Dallas and State of Arkansas, have invented new and useful Improvements in Railroad Constructions, of which the following is a specification.

The invention relates to an improvement in railroad construction, and particularly to a metallic bed or support for the rails.

The main object of the present invention is the provision of a metallic rail support coextensive with the length of the rails and adapted to effectively bind the rails in properly engaged positions and prevent independent movement of the rail ends when connected.

The invention will be described in the fol lowing specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a plan illustrating my improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a perspective of one of the securing bolts or rivets. Fig. 1 is a section on line 44 of Fig. 1.

Referring particularly to the drawings, my improved metallic railroad bed is made up in independent sections designed to underlie each rail. Each section comprises a base plate 1, which is preferably of materially greater width than the width of the base flange of the rail and is of substantial length and thickness.

Secured to the underside of the base plate is what I term a reinforce plate 2, comprising a section of material of less width than that of the base plate and centrally formedwith a longitudinally arranged depending web 3, preferably made up by suitably bending the material. The reinforce plate is secured to the base plate through the medium of rivets 4, which unite the plates at equidistant points I longitudinally thereof and are so relatively spaced transverse the base plate 1 that said rivets when headed will partially overlie the edges of the rail.fiange, thereby aiding in securing the rails to the base plate. The reinforce plate 2 is secured to the base plate so that the web 3 directly underlies the web of the rail, thereby materially strengthening the structure at this point and preventing any bending of the plate in use.

As an additional aid in securing the rails to the base plate 1 certain of the rivets 4, preferably each alternate rivet is provided with a clamping bar 5 and formed with an opening to permit passage of the rivet proper and reduced at 6 on the relatively lower surface to overlie the edge of the rail. Through the use of the clamping bar the rails are securely clamped or fixed to the base plate 1 and any tilting or independent movement of the rails in use is effectively prevented.

In connection with the rail support described I utilize a gage bar 7 comprising a strip of metal formed near each end with an offset portion 8 to receive the reinforce plate 2 and with a depression 9 to receive the rib 3 of the reinforce plate. The gage bars are located at any desired intervals hroughout the length of the track and are secured in place through the medium of the rivets 4: at the point of connection of the gage bar with the track support and also through additional rivets 10 disposed beyond the plane of the rivets 1, as clearly seen in Figs. 1 and 4. The gage bars are to be formed with the depressions 9 at normal gage, thereby insuring in the use of these gage bars that the rails will be maintained at gage throughout the length of the track.

The base plates 1 are of such length and so arranged that their oints break with the joints of the rails which they support, so that the rail joints rest upon a solid length of one plate, and the joints of the plates are preferably disposed directly opposite the oints of the opposing rail. This particular arrangement is desirable as I am thereby enabled to utilize one of the gage bars directly beneath the joints of the supporting plate of one rail support and the rail joint of the other track section, as shown in Fig. 1. As the gage bars are of substantial width a most elfeotive reinforce at the joint is thus provided, thereby materially strengthening my structure at the point where such structures are ordinarily weak.

The supporting plates 1 are preferably of such width as to form a substantial bearing for the rails, and with the ribs 3 of the reinforce plate seated in the road-bed, it will be obvious that tilting of the rails or other independent movement of the support of this invention is practically impossible. The reinforce plate tends to prevent any bending of the reinforce plate 1, while at the same time insures a substantial grip of the entire support in the re ad-bed, through the medium of the rib.

Having thus described the invention What is claimed as new, is

1. A metallic rail support comprising a base plate of greater Width than the flange of the rail, a reinforcing plate secured beneath the base plate, means for securing the rail to the base plate, and means for connecting the reinforcing plates of the respective rail supports.

2. A metallic support for railroad rails comprising a base plate, areinforcing plate secured beneath the base plate and formed with a dependent rib, and gage bars connecting the reinforcing plates of the respective rail supports, said gage bars being formed. to receive the ribs of each reinforcing plate.

3. A metallic support for railroad rails comprising a base plate, a reinforcing plate secured beneath the base plate and formed With a dependent rib, gage bars connecting the reinforcing plates of the respective rail supports, said. gage bars being formed to receive the ribs of each reinforcing plate, and rivets uniting the reinforcing plate and base plate, said rivets overlying the edge of the railroad rail flange.

4. A. metallic support for railroad rails comprising a base plate, a reinforcing plate secured beneath the base plate and formed With a dependent rib, gage bars connecting the reinforcing plates of the respective rail supports, said gage bars being formed to receive the ribs of each reinforcing plate, rivets uniting the reinforcing plates and base plate, said rivets overlying the edge of the railroad rail flange, and clamping bars secured on said rivets to overlie and bear upon the rail flange.

5. A metallic support for railroad rails comprising a base plate, a reinforcing plate secured beneath the base plate and formed with a dependent rib, and gage bars connecting the reinforcing plates of the respective rail supports, said gage bars being formed to receive the reinforcing plates and rib thereof.

In testimony whereof, I afliX my signature inpresence of two Witnesses.

CARL R. BOWEN.
