RAILROAD-TIE.

Application filed February '7, 1920.

To all 'iv/0m t may concern:

Be it known that l, VILLARD TALnorr, a citizen of the United States, residing at Spokane, in the county of Spokane and State of lVashington, have invented a new anduseful Railroad-Tie, of which the following is a specication.

rllhe device forming the subject matter of this application is arailroad tie, and one object of the invention is to provide novel means whereby the tie will be prevented from moving in the direction of its length, on the ballast. Another object of the invention is to provide an improved rail holding means. l

A further object of the invention is to improve the tie, as an article ofmanufacture, by preparing the same to receive rail holding means, and, at the same time, so constructing the tie that moisture cannot nd its way into the openings which are adapted to receive the rail holding means.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combina- Ition and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in longitudinal section, a tie constructed in accordance with the invention, parts of the tie being broken away; Fig. .2 is a perspective view showing the tie per se; Fig. 3 is a fragmental top plan of the tie; and Fig. 4 is a cross section taken on the line 4 4 of Fig. 1.

In carrying out the invention there is provided a tie 1 which preferably, although not necessarily is made of wood. In the lower surface of the tie 1, notches 2 are fashioned. The notches 2 may be of any desired contour. Preferably, however, they are of semi-circular form, there being, between the notches 2,

.supporting areas 3 of considerable extent.

serial No. 357,057.

There may be as many or as few of the notches 2 in the bottom of the tie as occasion may demand.

Openings 4 are fashioned in the upper surface of the tie 1, the openings converging as they extend downwardly. Each opening 4 includes an upper cylindrical part 5 and a lower cylindrical part 6, the part 6 of the opening being of less diameter than the part 5 thereof. In the openings 4, a water-proof cementitious filler 7 is placed. If desired, the filler may consist of tar. The material indicated at 7 completely fills the openings 4 and seals them hermetically. Therefore, the tie, as an article of manufacture, cannot rot or become damaged by water finding its way into the openings 4. It is to be understood that, in practice, all of the openings 4 are filled with the substance indicated at 7, one of the openings being empty in Fig. 1, in order that the contour of the opening may appear clearly in the drawings.

Rail holding means in the form of lag screws are provided, each lag screw including a body 8, a threaded end 9, a head 10 and a tapered neck 11 connecting the head with the body. The rails are shown at 12, the base flanges of the rails resting on the tie. The lag screws are threaded into the openings 4 and are held securely therein by the filler 7 the threaded ends 9 of the lag screws occupying the lower parts 6 of the openings, the bodies of the lag screws occupying the portions 5 of the openings. Since the openings 4 are reduced adjacent to their lower ends as indicated at 6, the lag screws will have a secure hold on the tie. The heads 10 of the lag screws engage the edges of the flange 14 of the rail 12, the necks 11 coperating with the extreme outer edges of the flange 14 of the rail 12. Since the necks 11 of the lag screws are of conical form, and are concaved, they will engage closely with the extreme outer edges of the flange 14 and afford a firm hold on the rail.

If desired, the' entire surface of the tie may be covered with a waterproof cementitious filler.

Having thus described the invention, what is claimed is ln a device of the class described, a railroad tie; a rail including a base flange resting on the tie; and lag screws threaded into In testimony that I claim the foregoing as ythe tie in converging relation, the lag screws my own, I have hereto aXed my signature including heads overhanging the base flange in the presence of tWo Witnesses.
