METALLIC RAILROAD-TIE.

Specification of Letters Patent.

This invention relates rimarily to railroad ties, has especial re erence to metallic ties and means for securing railroad rails thereto, has for its object the construction of a durable tie and its accessories, which can be readily manufactured at comparatively small cost.

The invention consists in certain improvements in construction, which will be fully disclosed in the following specification and claims.

In the accompanying drawings which form part of this specification :Figure 1 represents a plan view, of part of a railroad tie embodying the invention. Fig. 2 a vertical longitudinal section of the tie and a transverse section of the rail partly in elevation. Fig. 3 a plan view of a section of the tie, and Fig. 4 a side and end view of one of the clamps.

Reference being had to the drawings and the designating characters thereon, the numeral 1 indicates a hollow metallic railroad tie of our improved construction, on the upper surface of which are depressions 2, 2, one at each end forming seats or bearings 3 for a railroad rail.

cess is a vertical wall 4 thickened or reinforced to receive a bolt as will be hereinafter described.

5 5, indicate slots in the seats 3 enlarged at t elr outer ends 6, for the insertion of the inner end 7 of a clamping-member, in which are formed grooves 8, 8, to engage the metal in. the seat 3, and on the outer end of said member is ajaw 9 which engages the fishplate 10 of a rail joint or the flan e 11 of a rail 12 at points intervening the fish-plates.

The clamping-members are adjusted and secured in position by bolts 13, the threaded ends 14 of which engage the opposite reininforced walls 4, of the tie, and the opposite ends of the bolts engage the clamping-members, as by a recess 15, 1nto which the part 16 of the bolt extends, and is secured against On each end of the returning after the members have been properly adjusted and the rail secured in position, by a cotter-pin 17, which extends transversely through the member and the part 16 of the bolt.

The bolts 13 are provided with a head 13 and may also be provided with a nut 18 bearing against the wall 4 and a jam-nut 19, or other suitable lock-nut device.

In the bottom 20 of the tie is a slot 21 for draining the tie of water which may enter through the slots 5, 5, and on each side of the slot are transverse projections 22, preferably arranged at an angle across the tie, for the purpose of preventing longitudinal creeping of the tie in the roadbed.

The seats 3 for the rail are made wider than the base or flange of the rail 12 to allow for proper alinement 0f the rail on the tie by adjusting the screw bolts 13 and the clampingmembers, and when properly alined, the rails are secured in position by locking the bolts to prevent their accidentally turning and becoming loose.

l/Vhen signal wires are supported in the clamping-members, suitable insulating material 24, such as hard rubber, mica or the like is interposed between the clampingmembers and the rail to prevent transmission of the electric-current to the rail.

The tie thus constructed and equipped with rail securing devices forms a cheap and advantageous means for supporting railroad rails, can be readily made at comparatively small cost, and are durable and easily manipulated.

Having thus fully described our invention, what we claim is-- 1. A hollow metallic railroad-tie having depressed rail-seats formed in the upper wall thereof, permanent vertical walls at both ends of the seats extending across the tie, rail-clamping members engaging said upper wall and adjustable therein, and means separate from, but engaging sa1d clamping members and engagin the walls at the ends of said seats for ad usting and securing said members in engagement with a ran 2. A hollow metallic railroad-tie having depressed rail-seats formed in the upper wall thereof, permanent vertical walls at both ends of the seats extending across the tie, slots in the seats, rail-clamping members having grooves in their sides engaging the Patented Mar. 22, 1910.

'Wall of the tie and adjustable in said upper and bolts separate from, but. engaging slots,- said clamping-members, v at the ends of said seats and adjustable therein for securing said members: in; en-. gagement with the rail.

3., A depressed rail-seats formed in the upper wall thereof, permanent vertical walls at both ends of the seats extending across the tie,- slots in the seats, clamping-anembers in said slots-and engaging the upper wall of the tie, and separate bolts adjustablein-the-walls at the ends of" the sea-ts and engaging said clamping-members.

4. hollow-metallic railroad-tie having depressed rail seat-sformed in; the upper wall thereof, a permanent'reinforced wall at each end of said seats, slotsin the seats, cl 'am-pin-g memb'ershaving grooves in their sides; forengaging the upper' walllof thetie,

engaging the walls.

bolts separate from the clamping members adj ustablein said reinforced. walls and en- I gaging the clamping-members.

5; A hollow metallic railroad-tie having a depression-forming a rail seat at each end,

opposite slots in each seat,"a reinforced wall at each end of each seat, a. longitudinal drain slot in the bottom of the tie, and transverse projections thereon, in combination with rail-clamping members engaging the slots in the rail seats, and bolts for securing said members inengagement with: a rail:
