To all whom it concern:

Be it known thatI, W'ILLIAM F. Monar- SON, av citizen of the United States, residing at Cowell, in the county of Contra Costa and State of California, have iuventednew aiid useful Improvements in Steel and Concrete Railway-Ties, of which the following is a specification.

concrete avith the rails laid thereon; Fig. 2 is an enlarged perspective view of an ,end of a tie; Fig. 3 is a similar view of said end, the plates being removed.

Referring to the drawing, 1 indicates a metallic longitudinal casing, the lower portion of which is rectangular in form, and is filled with concrete 2, while the upper portion has sloped or beveled edges 3, between which and the upper'side 4.- of the casing a block 5 of wood is supported upon the 2. Said wooden block thus forms a cushion, reducing the effect of shocks or jars before they reach the concrete body, so that the concrete is rendered less liable to crack or break from said shocks.

The upper side 4 of the casing, near each end thereof, is formedwith a transverse upwardly extending rib 18' having a vertical inner shoulder 19, and in said up per side 4 there are formed, near said ribs and ad acent to the beveled edges 3,

two longitudinal slots. (3, each of which at its center is enlarged, as shown at 7, to receive the heads 8 of bolts 9, the upper surface of the wooden block 51 being recessed, or cut away, as shown at 10, to allow said heads to slide longitudinally therein, so that the stems of said bolts can move in said slots to the ends thereof. In this position the upper ends 11 are adapted to pass through apertures in plates 12, of which I provide, for each end of the tie, two, placed side by side, with theirouter ends abutting Specification or Letterslateirt.

Y which just themselves in the proper position for against theQvertical shoulder 19 of the 18 as clearly shown in Fig. 2, each plate be ngsecured to the casing of the tie by nuts 13'screwed upon the upperends 11 of the two belts in the corresponding slot 6.

However, should said plates not have been Patented Apr. 2, 1912: Ap lication filed November 1, 1911. Serial No. 657,972. q 4

placed originally in proper position they will,'by the outward thrust of the train transmitted to them as hereinafter described, be. moved outward so that their" out-ward endsabut against said shoulder 19.

Each plate 12 is formed with a lug' or' lip 14, cut out therefrom, as shown at 15,- the lug of one of said plates bein adjacent to one end thereof, and the leg 0 the other plate being adjacent to the opposite end; Before the rails are laid upon the tiessaid lugs extend upwardly, as shown in Fig. 2,

but, when said rails have been so laid, they are bent downwardly one over each flan e of the rail. The function of said lugs is merely to hold the flange of the rail down to the plate, and I do not relynpon them principally, if at all, to prevent the rails from spreading. To resist the rail-thrust,

said plates are formed with shoulders l6,,'

17, which are in line with each other and also with that one of the two lugs 14: which is intended to engage the outer flange of the rail. Said shoulders 16, 17, thus receive the direct outward thrust on the rails, and transmit it-to the plates 12, and itis then receivcd by the shoulder 19 and trans mitted to the casing l.

To detach the rails'from the plates for the purpose of substitution or otherwise, the nuts 13 are unscrewed from the bolts 9,

whereupon the plate having the .outer lug,

that to the left in Fig. 2, can readily be withdrawn from the rail. The other plate can also be withdrawn, as it is then comparatively easy to depress the plate from the rail, or raise the flange of the rail from the plate.

I thus provide a railway tie. of extreme strength and durability which will, much better than ties as at present constructed, prevent the rails from spreadin' with the rails will automatically aduse. and with which the rails can readily and replaced when desired.
