WILLIAM HENRY MORGAN, Q13 ALLIANCE, OHIO.

RAILROAD CONSTRUCTION.

Specification of Letters Patent.

Application filed November 29, 1912. Serial No. 734,098.

To all whom it may concern:

Be it known that I, WILLIAM H. MORGAN, of Alliance, in the county of Stark and Stateof Ohio, have invented certain new and useful Improvements in Railroad Con struction; and I do hereby declare the fol:

lowing to be a full, clear, and exact descrip-' tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in railroad construction designed particularly for subways or tunnels in which the track is laid on a concrete base.

In subways or tunnels designed for one track, there is not room sufficient between the rails and the side walls of the tunnel, for the endwise insertion and removal of the ties, hence it is necessary to make the ties in short sections to support one rail only. It has been found to be diflicult and expensive to secure the short ties against movement and maintain the proper alinement of the track, and the object of my invention is to provide an improved tie, and improvedmeans for securing the same to the track bed, and my invention consists in the details of construction as will be more fully described and pointed out in the claims. 7

In the accompanying drawings, Figure 1 is a view in transverse section of a tunnel showing my improvement. Fig. 2 is an enlarged view of one of the ties and the rail thereon and Fig. 3 is a view in vertical transverse section through the tie and its bed, and showing the rail in elevation.

1 represents the casing made of metal, in sections as shown; 2 is the concrete floor or track bed, and 3 is a gutter or drain in termediate the ends of the ties.

4: represents the ties, which, instead of being of a length suflicient to support and connect both rails'5, support one rail only, and are anchored to the floor or track bed of the tunnel. These short ties, are made of metal, preferably I-shape in cross section, the lower flange 4: being wider than the upper flange and bent downwardly at opposite sides of the web or body P of the tie into the base 2, so as to packclosely around and under the bottom flange l of the ties 4 and around the body of the latter up to or-nearly up to the topv flange. The top flanges 4 of the ties are flat for the attachment of the shock absorbing seats 8. These seats are spot or line welded to the ties, with their ends projecting at the front and rear of the ties, and are bent upwardly at their ends as shown in dotted lines in Fig. 3, so as to form spring seats or shock absorbers for the rail supporting chair 9. Each chair is provided with downwardly projecting flanges 9 adapted to engage the side edges of its shock absorbing seats 8, and with upwardly projecting flanges 9 adapted to form lateral supports for the bottom flange 5 of the rail 5.- The chairs 9, and rails 5, are secured to the seats 8 and hence to the ties, by the spring clamps 10, substantially as disclosed in my Patent No. 1,026,108 granted May 14th, 1912, or as disclosed in my Patent No. 1,046,836 granted December 10, 1912.

Instead of permanently securing the metal ties in the pockets by a filling 7 as above explained, the concrete covering for the metal ties, may be applied to the ties and permitted to set before the composite concrete and metal ties are set into the pockets. These pockets may be closed at both ends and sides, or the inner ends may open into the central drain 3 as shown. With this'construction, and also the construction previously described, there is no possibility of any outward displacement or tipping of either rail, and there are no stresses tending to displace them inwardly or toward each other. Again the ties being short can be withdrawn inwardly, as the space between the two rails of a track is greater than the length of the ties.

It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described, but

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

1. In a railroad construction for tunnels or subways, the combination of a concrete track-bed having pockets therein under each line of rails of the track and metal ties permanently attached to, concrete bases the latter being located within said pockets.

' 2. In railroad construction ior tunnels and subways, the combination of a concrete track beclhaving two sets of spaced pockets therein, one set for each line of rails, and short metal ties permanently attached to concrete bases the latter being located within said spaced pockets 3. In railroad construction for tunnels and subways, the combination of a concrete track bed having two sets of spaced pockets,

In testimony whereof, I'have signed this specification in the presence of two subscribing witnesses.

XVILLIAM HENRY MORGAN.
