RAILROAD-TIE.

Specification of Letters Patent.

Patented lllar. 3, 19230,

Application filed. December 15, 1919. Serial No. 345,131..

To all whom it may concern:

Be it known that I, ALBERT R. STEPHEN- son, citizen of the United States, residing at Jackson, in the county of Jackson and Eltato of Ohio, have invented certain new and useful Improvenlents in Railroad-Ties, of which the following is a. specification, reference beinghad to the accompanying drawings.

This invention relates to railroad ties and particularly to a concrete tie.

The disadvantage of the old wooden tie is that the weight ofthe train causes pressure on one side of each rail with the result that the spikes become loosened and the rails spread. W hen the rails are adjusted to the proper gage and new spikes applied, the old spike holes fill with water and the tie decays in a short time.

It is therefore the object of this invention to provide a tie wherein the rail fastening means do not receive the stress of the side pressure of the rail so that the holding power of said means is not decreased at any time.

Another object is to provide a tie composed of a pair of sections through which an adjustable bolt is passed for connecting the sections and adjusting the rails to the proper gage and which receives the stress of side pressure of the rails through the medium of the sections of the tie.

" means for securing the rails to the tie.

Another object is the provision of a device of this character inch ding a rail chair which prevents the rail fastening means from dama 'ing the tie.

-With these and other objects in view the invention consists in the improved construction and arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a railroad rail 7. A. rail chair 8 is positioned within the channel and has its longitudinal mar ginal edges 9 extending over and lying in the plane of the upper surfacoof the tie. The marginaledges 9 of the rail chair have a plurality of openings 10 through which rail securing bolts 11 are passed. Each bolt is provided with a clamp 12 adapted to en gage the base of the rail. Registering openings 13 are formed in the tie for the reception of the bolts. Embedded in each section of the tie and extending transversely thereof are a pair of reinforcing bars 14, provided with threaded openings 15 adapted to re ceive the lower ends of the bolts 11. The fastening bolts do not engage the tie, but the longitudinal marginal edges of the rail chair through the medium of the clamps 12. A bolt 16 extends through the sections 5 and 6 to connect the section in spaced relation to each other, the head of the bolt engaging one section, while the nut 18 of the bolt engages the other section.

After the tie sections and rails are posi. tioned in a road bed, if the gage of the rails is too narrow, the nut 18 may be loosened, and the section that is out of alineinent can be manually forced outwardly by a suitable implement, beyond the proper The nut is then rotated into engagement with the section and by holding one of the sections stationary, the section being adjusted can be forced inwardly by the nut and bolt to the exact gage required. Of course, the operation of forcing the sections outwardly is only necessary when placing new rails and ties in the road bed, the side pressure of the train has a tendency to force the rails away from each other. Therefore, the only adjustment that is required after the tie sections and rails are in position is that of forcing the sections toward each other to adjust the gage of the rails which have been. spread by the side pressure of the train.

Thetie sections are formed by inserting the bolts without their clamps through the openings in the marginal edges of the rail chair, and threading them into the reinforcing bars 14. V A core is inserted in the mold to provide for the opening through which the connecting bolt passes. The parts above mentioned are placed upside down in the mold, that is with the rail chair disposed in engagement with the bottom of the mold, the bolts 11 being greased to prevent the adherence of the concrete thereto. lhe first portion of concrete includes a proportion of one to two of fine crushed gravel. The rest of the section includes a rich mixture with fine crushed gravel. After the composition has entirely set, the bolts are removed to permit the block to thoroughly cure.

One of these ties takes the place of two of the old form of wooden ties. In addition to this, all the Weight appliedto one rail is transmitted to only one section of the tie, so that each section equall supports the Weight of the train, and therel iy eliminates the unequal application of stress. Furthermore, the bolt that connects the sections in spaced relation also permits the same to be adjusted to the gage desired. Each section of the tie is embedded in the road bed so that the danger of freezing is eliminated.

The invention having been set forth, what is claimed as new and useful is A railroad tie comprising spaced tie blocks, having a rail channel in each block, a rail chair disposed in said channel and having its longitudinal marginal edges lying flush with the upper surface of the block, reinforcing bars embedded in each block and extending transversely of said block, rail. engaging bolts extending through openings in the marginal edges of the chair, rail engaging clamps on said bolts, the ends of each pair of bolts being threaded into one of the transversely extending reinforcing bars, a bolt for connecting said sections, the head of the bolt being engaged with the outer side of one section, and a nut threaded on the bolt to engage the outer side of the other section whereby the gage of the rails may be adjusted.

in testimony whereof I hereunto afiix my signature.

ALBERT R. STEPHENSON.
