To all whom it may concern:

Be it known that I, SUMNER E. STREETER, a citizen of the United States, residing at Dearborn, in the county of Platte and State of Missouri, have invented certain new and useful Improvements in Perforated Metallic Railroad-Ties, of which the following is a specification.

My object in this device is to provide a flexible self-gaging, hollow, perforated, metallic railroad tie as a substitute for the wooden tie now in general use; it is designed for standard gage or other gage railroads now in operation, or that may hereafter be constructed' I I attain my object by the mechanism shown in the accompanying drawings, in which,

Figure 1 is a perspective view of a completed tie with railroad rails in place thereon. the rails broken away to show the clamps; Fig. 2 is an enlarged detail of a drop bolt for fastening the clamps to the rail flanges, the rails broken away to show the clamps; Fig. 3 is a side view of a loose clamp with a right angle end to lit in a slot in a tie; Fig. 4 is a top view of said loose clamp showing cut-outs in the sides thereof to permit easy removal or adjustment; Fig. 5 presents three views comprising, a side, plan and cross section of a splice bar; Fig. 6 is a top view of the tie showing the rails clamped in place; Fig. 7 is a cross sectional view of a tie and a cross sectional view of the rails in position; Fig. 8 is a cross section of Fig. 6 taken from points III and IV showing the rail held in place by a stationary' clamp a loose clamp and a drop bolt; Fig. 9 is a cross section of the tie taken from points V to VI on Fig. 7, and Fig. 10 is an enlarged detail of the top view of that part of the tie carrying the rail showing the rail and clamps, the clamps being in position.

Similar letters refer to corresponding parts throughout the several views.

My metallic railroad tie is preferably made of one-fourth inch, or heavier, pressed metal,.is hollow and perforated with round, square, oblong or other shaped openings at the sides and top to lessen rigidity and to also permit the roadbed and ballast to enter into and form a part of the completed tie. One outside stationary rail clamp B and one inside stationary rail clamp B are cut out square or octagonal shaped nut I.

and raised from the tie itself in'the process of malnng. Opposite each of said stationary rall clamps on the opposite side of the rail there is a loose rail clamp N, Figs. 3 and 4, provlded with hole C for a drop bolt M of similar formation. to the stationary rail clamp B where loose rail clamp N'covers the rail flange, but extends outward flatwise along the tie and terminates in a right angle D which fits in a slot E in the tie to prevent sllpplng or spreading of rails. At each side of a loose rail clamp at points K and K, Fig. 4, there are half round or square cutouts to permit the removal of loose rail clamps N N past small stationary guides L and L, pressed out of the tie, which prevent the slipping of said loose clamps while in made of one-half inch, or larger metal, and

has a square head H at one end and the other end being threaded and supplied with a The bodyof the drop bolt, when in place, is be= neath that part of the tie F lying under rail 0, thus drawing that part of tie F solidly against the underneath surface of rail 0 and the rail flanges firmly to the top of the tie by the downward pressure of the clamps when nut I on drop bolt M is tightened at the threaded end of said drop bolt. The drop bolt enters the loose clamp from underneath through a'slotted opening in the tie which permits adjustment to any width'of ra1l base. Any'make of fish plate may be used for connecting the rails when this tie is used, provided that part of the fish plate resting on the rail flange is cut away sufliciently at each end, J, J Fig. 5, of the plate to permit rail clamps B B and N N to fit propgrly against the rail flange, as shown in A special fish plate design, Fig. 5, is submitted herewith as a necessary part of the completed working tie.

I am aware that hollow metal railway ties wlth openings or perforations therein have heretofore been constructed, but

What I claim and desire to secure by Letflanges of a railway, of a drop bolt and sta tionary and loose clamps, the drop bolt drawing said clamps downward against said flanges and holding the rails rigidly to the tie, the ends of said drop bolt extending upward and outward at opposite angles, one end provided with a head, the other end threaded and provided with a nut.

2. The combination of a metallic tie having a slot and a plurality of openings, a'

loose clamp, a right angle end thereon adapted to engage with said slot, and cutouts to clear raised guides in the tie, said guides preventing side motion of said loose clamp.

3. A hollow, flexible, perforated metallic railway tie made of one piece of pressed steel embracing as a part of the tie two stationary rail clamps each provided with a hole for the reception of a drop bolt, two loose clamps, raised guides on each side of the loose clamps to prevent side motion of
