To all whom it may concern.-

Be it known that I, VILLLUI Gnonon MARTAN, a eitizen'of the United States, re siding at Otter (reek, in the county ol Levy. State of Florida, have invented certain new and useful Improvements in Metallic Raillies; and I do hereby declare the iollowinp to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has rel'erence generally to .metallic railroad-ties, and especially to ties of that type provided with bearers interior-l arranged and actinp as supports for the top portion of the ties when a train is passing over the rails la' l thereon.

The objects of the invention include the provision of means for retaining the bearers in place within the ties, the provision of supports located on the under side of the top portion oi the ties adjacent the bolts passing, through the rails for preventing any movement thereof, and the lormation in one side of the ties of semicircular o 'icnings by means of which access is had to theinterior of the ties and the nuts held in place on the railbolts when the latter are tightened. I

'With the above and other ends in view the invention consists in the construction, combination, and arrangement oiparts,all as hereinatter l'ull v described, specifically claimed, and illustrated in theaccompanying drawings, in which-- Figure l is a plan view of a tic constructed in accordam-c with this invention. Fig. 2 is a longitudinal horizontal section through the tic. big. I) is a transverse vertical section taken on the line I) It oi l ig. lv Fig. -3 is a dctail view, in side elevation, of a port ion ol the tic shown in Fig. I. Fig. :3 is an enlarged dot ail view of one ol' the I'aildmits.

liike parts are designated by correspond- ,inp; rclcrcncc-numcrals in the several views.

el'errin g more particuiarly to the draw in gs, the tie is shown as tubular in l'orm, prol'ei'ahl v rectangular in crosssection, and constructed of steel or galvanized iron. riccurcd to the under face of the top portion of the tie at opposite ends thcrcol is an X- shaped brat-c t3, the members of which interlock with each other, as indicated by the numeral 7. The n'iembers of said brace may be face of the tie or, if preferred, may be cast integral with the tie.

The upper face of the tie is provided with a series ol openings 8, arranged adjacent each brace t3 and following generally the shape thereof, so that the general appearance of each set of openings is likewise that of the, letter X. 'lhrough said openings the railbolts are passed, the heads thereof hearing against the bottom portion ot the rails and the threaded ends extending into the interior of the ties. The heads 1] of said bolts are formed with a rectangular projection 12, by means oiwhich the. bolts may be rotated by a wrench or other tool.

Owing: to the arrangement of the openings 8 as described, it will be obvious that any size rails 9 may be secured to the ties by merely fitting;- the rail-bolts in the corre sponding openings.

Mounted within the interior of the tie on opposite sides of each brace 6 is a pair of bearers l3, bolted or secured in any other preferred way to the ties. The outer member of each pair of bearers is further held in place by means oi a pair ol longitudinallydisposed metal strips 14, secured to the under face of the top portion of the tie and bearing at. their inner ends against the outer face of said bearers. The several bearers thus strengthen and support the tie at its weakest point---i. In, beneath the rails-and the outer member of each pair of bearers is further held in place by the strips l4, as above described.

One side of the tie is provided with a pair of semicircular openings 15, cornmunicating with the interior of the tie between each pair of bearers, the purpose of such openings being to permit access to the interior of the tie to allow the workmen to attach the nuts lti to the rail-bolts it) in proper position with respect to the X-shaped braces ti. 'llie bolts are then tightened through the projections 12 on their ends, as above described.

' so positioned, one tide of each of the several nuts will contact or approxinlately contact with the corresponding' brace member, and any rotat ion of the nuts will he therefore prevented, thus holding; the same firmly in their tightened position The end members of the bearers may be l formed adjacent their bottom edges with a separateiv lornied and bolted to the under l drain-hole to l're'e the tie ol any water which I that rails of any desired size may be used in connection with the ties, and, finally, that the disposition of the X-shaped braces within the tie will prevent any rotation of the I track-bolt nuts, the openings in the tie side enabling the workmen to readily position the nuts upon the bolts prior to their tightening. The invention is susceptible of obvious ,znodifications and changes within the scope of and without departing from the spirit of the -appended claims, and limitation to the exact details of construction shown and described is therefore not intended.

What is claimed is v 1. A hollow metallic tie provided at opposite ends with a paimof spaced bearers interiorly arranged therein and located below the rails mounted on the tie,,one side of said tie having an opening communicating with the space between each pair of bearers, to permit access thereto.

2. The combination, with a hollow metallic tie, and rails mounted thereon, of bolts for securing said rails in place, the lower ends of said bolts extending into the interior of the tie, and means located adjacent the un der face of the tie for retaining said bolts in openings communicating with its interior for permitting access to said means.

3. The combination, with a hollow metallic tie, and rails mounted thereon, of bolts for securing said rails in place, the lower ends of said bolts extending into the interior of the tie, nuts mounted on the lower ends of said bolts for retaining said bolts in place, and means mounted upon the under face of the top portion of the tie for preventing movement of the nuts, one side of said tie being provided with openings communicating with its interior for permitting access to said means. a

4. The combination, with a hollow metallic tie, and rails mounted thereon, of bolts for securing said rails in place, the lower ends of said bolts extending into the interior of the tie, nuts mounted on the lower ends of said bolts, and an X-shaped bracesecured to the under face of the top portion of the tie at opposite ends thereof and in contact with one side of the nuts, for preventing movement thereof, one side of said tie being provided with openings communicating with its interior for permitting access to said nuts, bolts, and braces.

In testimony whereof I affix my signature in presence of two witnesses.
