RAILROAD TIE.

Y Aeplicetiea led November Si 1924- ATo all z 0-[tom t may concern:

Eer it known that I, FREDERICK T. SPATH, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of* Minnesota, have invented certain new and useful Improvements in Railroad Ties; and l do hereby declare the followfof .material to give the mairimum of strength and .eeienovl I t is an additional object in such a tie to provide means thereon for preventing lateral and longitudinal displacement or -creeping land also prevent the roadbed between the ends ,of ythe tie from washing out. I

It is an additional object to resiliently reinforce atieV et the PertQnS there-QH t0 which lthe rails er@ SiC-.Ulti

To these ends, generally stated, .the invention consists voi the novel deviees and combinations. of .dvis herein described and set forth in the claims.

The invention is illustrated in the accompanying drawings, wherein like notations refer to similar parts throughout the several views, and in which,

Fig. l is an elevation of the tie applied to the road bed;

Fig. 2 is a plan view of the same, with some parts broken away; and

Fig. 8 is a cross section taken on the line SMB of Fig. l.

In the preferred form of the invention illustrated, an elongated body member is designated by the numeral 4, constructed of rolled steel or malleable iron, of relatively thin cross section, having downwardly and inwardly curved end portions 5, of hook-shaped cross section. These hookshaped ends have aligned substantially rectangular slots in the opposite sides thereof, through which blade-shaped stakes 6 are adapted to be passed or driven and further driven into the roadbed to firmly secure the tie against creeping or lateral displacement, A plurality of rugged clips Serial No. 748,561.

' are mounted on said body member 4 and secured thereto by headed bolts 8 and adapted to engage .the flanges of rails 9, at opposite sides thereof, to secure said rails to .the top ol body member 4. A pair of U-shaped reinit'orcing members or chairs 10 are riveted or otherwise secured to the bottom of body member 4, directly beneath the rails 9,. These U-shaped members are constructed oit, preferably, rolled steel having considerable degree of resiliency.

The ties are set in the roadbed with the body member 4 supported on the top thereof and with the hook-shaped end portions 5 gripping the central portion of the roadbed at either end .of the tie. In installing the tie, the roadbed is cut down to accommodate the depending portions thereof, including the hook shaped ends 5 and the U- Shaped members l0. The tie is then laid in proper position and said members packed with the sand or'dirt and the road bed then Athoroughly tamped .about .the ends and sides of said tie. The chairs l0 are also preferably ffilled with sand or roadbed material andthe stakes 6, are driven through the apertures in the ends 5 into theroadbed. The clips f? are then clamped down against the flanges of the rails to firmly secure Athe same to the top of body member 4. The stakes G should be about two and one-haiic feet in length.

it will be seen from the above description that the hook-.shaped extremities 5,-be ing inwardly curved, will grip the central portion oi the roadbed therebetween and prevent the same from washing out during rain, and also preventing any longitudinal slipping of the tie. The chairs 10 reinforce the portions of the body member 4, which the rails traverse, and also assist to prevent longitudinal movement kof the tie, giving the desired elasticity to the rail and reinforcing the same where the greatest strain is imposed.

The blade-shaped stakes 6, rigidly held in proper position in the slots formed in the hook-shaped ends 5, prevent lateral displacement or creepingl of the tie. The hook-shaped ends 5, therefore, not only afford gripping claws or anchors but also permit the stakes 6 to be rigidly braced, whereby it will be practically impossible for vibration from passing trains to work the stakes loose.

In repairing the rails, the clips may be readily loosened by unscrewing `the nuts on bolts 8, and if it is desired to replace the bolts, this may be readily effected by digging out the dirt in chair l() from the side of the rail, and `inserting a new bolt from the bottom of the body member 4f.

It Will be seen from the above description, that applicant has provided a rugged and highly efficient metallic railroad tie constructed on sound scientitic principles. Means are provided for preventing both longitudinal and lateral displacement of the tie, and also for preventing the dirt or sand between the ends thereof from Washing away. rlhe material used is little and the entire tie may be manufactured at small cost.

lt will, of course, be understood that various changes may be made in the form, details and arrangement of parts, Without departing from the scope of applicants invention.

TWhat is claimed is l. A railroad tie comprising an elongated body member having means thereon for securing rails thereto and having its eXtremities extended downwardly for some distance and in ardly to constitute anchoring and supporting members for said tie, trie outer surfaces of said downwardly extending portion consituting the extremities of the tie.

A railroad tie comprising an elongated body member of relatively thin cross-section having means thereon for securing rails thereto and having depending inwardly curved extremities constituting` anchoring` or supporting members for said tie and adapted to grip the road bed and present smooth rounded ends at the top of said road.

3. A railroad tie comprising an elongated body member having means thereon for securing rails thereto and having depending inwardly extending anchoring members adjacent the ends thereof and members carried by said anchoring members adapted to eX- tend into the road bed substantially parallel with the longitudinal edges of said body member to hold the tie against lateral displacement.

/L. A metallic railroad tie comprising an elongated body member having means thereon for securing rails thereto and having end portions of hook-shaped cross section provided with aligned apertures in the opposite sides of said hook-shaped ends, and stal-:es adapted to be driven through said apertures into the roadbed to secure said tie against lateral displacement.

5. A metallic railroad tie comprising an elongated body member of relatively thin material having means thereon for securing rails thereto and terminating in hookshaped portions adapted to grip the roadbed and prevent longitudinal displacement of said tie, said hook-shaped members having aligned slots on the opposite sides thereof, and a pair of blade-like stakes adapted to pass through said slots and be driven into said roadbed to hold the tie against lateral displacement.

6. n. metallic railroad tie comprising an elongated body member of relatively thin material having means thereon for securing rails thereto, U-shaped reinforcing members secured to said body member beneath said rail-securing means, and hook-shaped anchoring means on the extremities of said body member.

ln testimony whereof I affix my signature.

FREDERICK T. SPATH.
