RAILROAD-Tl E.

SPECIFICATION forming part of Letters Patent No. 363,020, dated May 1'7, 1887.

Application filed July 12, 1886. Serial No. 207,740.

To all whom, it may concern:

Be it known that I, LUKE TAYLOR, a citizen of the United States, residing at Butte Creek, in the county of Glackamas, State of Oregon, have invented certain new and useful lmprovements in Railroad-Ties, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention consists of a hollow railroadtie open at both ends. The top of the tie is flat, while the bottom, which is parallel with the top, is slightly concave on its under side. Both sides of the tie recede from the bottom upward at an equal angle until they join the top of the tie, forming in cross-section an equilateraltriangle having one of its angles out by a plane parallel with the opposite side. This form, which is adapted to be placed upon the surface of the ground, secures great stability and firmness, owing to its broad concave bottom, narrow top, and straight sloping sides.

The tie is made of one piece, and may be cast of iron, or made of papier-mach, vulcanized fiber, or any suitable material.

The interior of the tie may be coated with any suitable water-proof preparationsuch as tar, &cto protect it from moisture.

The top of the tie is provided with boltholes, through which pass screw-bolts for holding the rails. The screw-bolts may be secured with or without nuts.

In the accompanying drawings, Figure 1 is a view in perspective of the hollow tie, and Fig. 2 is shows the same with a flat bottom.

(No model.)

a view in cross-section of the same, and shows the tie with a slightly-concave bottom.

Similar letters of reference indicate similar parts in both the figures.

In the tie A, B represents the top; 0, the bottom; D D, the sloping sides; E E, the rails; F F, the apertures in the top plate, B, for the screw-bolts G G; and H H, the nuts holding the same, which, however, may be dispensed with.

A transverse ledge, I, may be provided across the top plate, B, against which rails E E may fit, in which case screw-bolts will be required on one side only of the rail. thus adding to the strength of the tie. This form is shown on one end of tie A, Fig. 1.

The open ends of the tie slope up from the bottom to the top at about the same angle as the sides. This, however, is not essential, and

the tie may be perpendicular at the ends, if 5 desired.

I am aware that ties of rectangular shape have been used, and I do not claim any such as of my invention; but

\rVhat I do claim, and desire to secure by Letters Patent, is-

In a hollow railroad-tie, a bottom flat on the inside and concave on the outside, substantially as described.

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

LUKE TAYLOR.
