RAILROAD-TIE.

Application filed April 3, 1919.

To all whom it may concern:

Be it known that I, URIE A. ORISSMAN, a citizen of the United States, residin at Burnham, in the county of Mifiiin and tate of Pennsylvania, have invented a new and useful Railroad-Tie, of which the following is a specification.

This invention relates to improvements in railway ties, and particularly to combination wood and metallic ties.

The main object of the invention is to provide a tie having the lasting qualities of steel, and at the same time possessing the resilient qualities as does the wooden tie now in common use.

A further object is to provide a tie which may be readily and easily repaired without necessitating the removal of the road bed.

In the drawings Figure 1 illustrates a side elevation of a railway tie constructed in accordance with my invention;

Fig. 2 is a horizontal sectional view showing the rail supporting blocks removed;

Fig. 3 is a detail view of one of the rail supporting blocks; and

Fig. 4 is a perspective view of the block securing means.

Referring to the drawing in detail, the numeral 5 indicates the base of a metallic tie frame. which is of a length equal to the length of the ordinary tie now in use, and includes the upstanding albutments 6 at either extremity thereof. Each of the abutments 6 is provided with flanges 7 which are a continuation of the ribs 8 extending upwardly along the upper edges of the base 5 and form therewith suitable pockets 9. Apertures 10 are provided in the base 5 between the ribs 8 and are for the purpose of permitting water which might collect on the base, to drain therefrom.

Rail supporting blocks 11 are of a width equal to the distance between the ribs 8, and have one of their ends beveled as at 12 to engage the inclined ends 13 of the fastening bar 14.

These inclined ends 13 of the fastening bar are also provided with extensions 15 which embrace the sides of the rail supporting blocks adjacent the beveled ends thereof, and prevent lateral movement of the rail supporting blocks 11 with relation to the base 5.

Adjacent the respective inclined ends of the Specification of Letters Patent.

Patented July 22, 1919.

Serial No. 287,135.

fastening bar 14 are openings 16 which register with openings 17 provided in the base 5, and receive the bolts 18 which pass therethrough and rigidly connect the fastening bar 14 with the base 5. Recesses 19 are pro vided in the under side of the base 5 to receive the heads 20 of said bolts 18 thereby preventing rotary movement of the bolts when the same are being positioned in their securing positions.

In assembling a metallic tie constructed in accordance with my invention, the base 5 is positioned in the road bed of a railroad, the rail supporting blocks are then positioned in the pockets 9. After the rail sup-- porting blocks are positioned in the pockets 9, the fastening bar 14 is positioned between the rail supporting blocks 11, and the bolts 18 are screwed home, with the result that the rail supporting blocks are forced into the pockets 9 by the fastening bar "14, due to the inclined ends 13 engaging the beveled ends 12 of the rail supporting blocks 11.

What is claimed is t 1. In a, railway tie a metallic base plate having abutments formed at its ends, said abutments having flanges. rail supporting blocks positioned within the flanges, a fastening bar positioned between the blocks and coiiperating therewith for holding the blocks to the tie and means for securing the fastening bar to the tie.

2. In a railway tie, a metallic base having pockets formed at its ends. rail supp-orting blocks positioned within the pockets. a fastening bar positioned between the rail supporting blocks. said rail supporting blocks and fastening bar being constructed to set up a wedging action therebetween when the fastening bar is bolted to the tie.

3. In a railway tie. a metallic base plate having a pocket at each of its ends. a rail supporting block positioned in each of the pockets. said blocks having beveled ends. a fastening bar positioned between said blocks, each of the ends of the fastening bar being inclined to engage the beveled ends. and means for securing the Fastening bar to the metallic base plate.

4. In a railwav tie. a metallic base plate having pockets formed in the respective ends thereof. a rail sup orting block positioned in each of the pockets. one end of each of the rail supporting blocks being inclined. a fastening bar positioned between the rail supporting blocks the ends of the fastenin In testimony that I claim the foregoing bar engugnig the inclined ends of the rai as my own, I have hereto affixed my signasupp-erting blocks, means on the ends of ture in the presellce of two witnesses.

said fastening bar for preventing lateral UR IEA. GRISSMAN. movement of the fastening bar and means Witnesses:
