` Specification of LettersiPatent. 19,18. V

Application filed March 14, 1917, Serial 110.154,88). Renewed. May 3,1918. `Serial No. 232,381.'

To all whom t may concern: i Be it known that I, LOUIS M. .CBARY, a citizen of the United States, residing at Hongkong, China, have finvented certain new and useful Improvements in Railway- Ties, of which the following is a specification.

The present'invention` relates to railway ties, and the primary object is to provide a structure of this character that will resist..

the action of the elements, and at the same time constitute an effective sleeper or tie.

A further and important object is to provide a device of this character that will not slew or creep, is relatively flexible, so that it will not be liable to break if unevenly packed or tamped,`and is furthermore constructed so that ordinary dog spikes, or other usual rail fasteners can be used Vwithout changing the methods or tools now employed in the construction and maintenance of railways.

An embodiment of the invention that is at present considered the preferable one is illustrated in the accompanying drawings, wherein Figure 1 is a top plan view of the tie,

Fig; 2'is ay bottom plan view,

Fig. 3 is a side elevation,

Fig. 4L is a horizontal longitudinalV sectional view on an' enlarged scale through one of the sleeper members,

Fig. 5 is a vertical sectional view taken on the line 5-5 of Fig. el.Y

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, two separate sleeper members 6 are employed that are preferably constructed of concrete, granite or other stone chips 7 being embedded in the lower sides of the members before the concrete has set, said chips projecting below the lower faces of the members so as to roughen the same and produce anchoring surfaces that will assist in preventing the slippingor creeping of the tie.

The two members are connected by spaced tie elements 8 that are preferably in the form of metal rods square in cross section. The end portions of said rods are embedded longitudinally in the sleeper members and have vertical eyes 9 also embedded in the members and disposed out of transverse alinement. The upper sides of receiving plugs ll that areembedded.` in the;

sleeper members and pass through lthe eyes 9. Y These plugs are preferably of wood, so that rail fastenersof practically any well vknown type may be driven thereinto.

In the first place, it will. be-evident that `the structure is relatively simple and can be easily and cheaply manufactured. The concrete sleeper members being separate structures and connected by the tie rods, are thus permitted to have a relative play, so that the danger' of breakage of the tie due to uneven tamping, is eliminated. The end portions of the tie rod extending longitudinally through the sleeper members, serve as reinforcements therefor, and to further reinforce the concrete structures, transverse rods of suitable formation, preferably twisted, may be employed, these rods being shown at12. The tie rods furthermore serve as securing means for the plugs 11, and these plugs being tapered, can be readily removed when they become decayed or incapacitated from any reason, so that new ones may be utilized without the necessity of an entirely new tie.V

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

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

1. In a railway tie, a sleeper member of concrete, anchor elements embedded in the under side of said member and projecting below the under face thereof, and means for securing a rail to the sleeper member.

2. In a railway tie, a'sleeper member of concrete, stone chips embedded in the under side of said member and projecting below the under face thereof, producing a roughenedanchor surface to prevent slipping of the tie, and means for securing a rail to the sleeper member.

B. Inatrailway'tie; the combination xv-itrht:

spaced sleeper members of concrete, V of,V spaced substantially straight tie barslocatedfv 51de by sid'e and connecting-the membere' nienlers "and:haringtlrielrd portions embeddedlongitudinally therein, Said tie bars having yerticalppenings through their einbedded body j bortlone, iastener receiving plugeembedded in the Sleeper members and passing through the openings or eyes, said `plugs bemg disposed in the longitudinal planes of the tie bars, and anchor elements embedded in the under sides off the sleeper members and projecting below the under faces thereof, the7 tie barsbeing. arrguigorh above said anchor elements.

In'xtestimony whereof, I affix, my ture in. the` presence of two Witnesses;

i `LOU-IS MEBTON` CRARY.
