UNITED STATES PATENT OFFICE.
MASAMICHI IGARASHI, OF TOKYO, JAPAN.
RAILWAY-SLEEPER.
Application filed November 29, 1919.
To all whom it may concern:
Be it known that I, MASAMIGHI IGARASHI, a subject of the Emperor of Japan residing at No. 93 Susakicho, Mukojima, l-Ionjoku, the city of Tokyo, the Empirefof Japan, have invented certain new and useful Improvements in Railway-Sleepers, entitled M. I. Railway Sleeper, of which. the following is a specification. V
-This invention relates to railway sleepers or ties of the kind having the rail supports lodged in pockets or recesses in the sleeper.
The primary objectof the present invention is to enable the rail supports to be more easily and cheaply removed and renewed than heretofore in sleepers of this kind.
7 This object is achieved by means of holding down members for the rail supports which traverse side walls of the pocket through holes in said walls, and fillings in said holes for fixing the holding down memhere.
The invention is more particularly intended for use in concrete and similar sleepers. In order that said invention may be clearly understood and readily carried into effect, the same is described more fully with reference to the accompanying drawings, in which Figure 1 is a longitudinal section of a railway sleeper in accordance with this invention, showing a rail fixed, by means of spikes, to a rail support consisting of a block of wood or like material firmly embedded in the pocket or recess in the sleeper, which is of reinforced concrete.
Fig. 2 is a plan showing the block embedded in the sleeper.
Fig. 3 is a cross section thereof.
In all figures, the same symbol represents asimilar part.
Referring to the drawings, a pocket or recess is formed in the sleeper A made of reinforced concrete, and a wooden block B is inserted in the recess, which has spike holes C as shown in Fig. 2 provided in its three sidewalls, a water discharge hole 0 being made in the bottom of said recess, and a space or. clearance (Z being provided around the block B, which space is filled with coal tar or asphalt and hemp, by means of which the block B is maintained in its proper position, while, at the same time, it serves the purpose of preventing rain or other water After thus Specification of Letters Patent.
Patented Jan. 25, 1921.
Serial No. 341,369.
setting the block spikes S are driven through the holes G into the block in such a manner that the heads of the spikes S slightly projeot on the outside of the side-walls of the recess, and the spaces in the spike holes C are filled with cement mortar to fix the spikes in position.
lVhen the block B is to be re )laced, the cement mortar in the spike holes is broken or crushed, whereby the spikes S can be withdrawn from said holes, which allows the block to be easily replaced without damage to the sleeper member; the rail Z may be fixed to the block either before or after the latter is secured to the sleeper member A.
Having now particularly described and ascertained the nature of said invention and in what manner the same is to be performed I declare that what I claim is:
1. In a railway tie having pockets therein at the rail crossings, rail supports in the pockets, holding down members for the supports, said members traversing side walls of the pockets through holes in the walls, and
fillings in said holes for fixing the holding down members.
2. In a railway tie of concrete having pockets therein at the rail crossings, wooden blocks in the pockets adapted to support the rails, members traversing side walls of the pockets through holes in the walls, and cement fillings in said holes fOr fixing the holding down members.
3. In a railway tie of concrete having pockets therein at the rail crossings, wooden blocks in the pockets adapted to support the rails, spikes traversing three side walls of the pockets through holes in the walls and MASAMIGHI IGARASHI.
