CONCRETE RAILWAY-HE.

SPECIFICATIONforming part of Letters Patent No. 761,647, dated June '7, 1904.`

Application led .Tune 8, 1903. Serial No. 160,451. (No model.)

To aZ whom it may concern." n

Be it known that We, LOUIS BEEZEP. and MICHAEL J. BEEZER, citizens of theUnited States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have in- -vented or discoverednew and useful Improvements in Concrete Railway-'.fies, of which the folloivingis a speciiication.

In the accompanying'drawings, which make part of this specification, Figure l isa plan of a tie constructed in accordance with our invention. Fig. 2 is a longitudinal section on the line 2 2 of Fig.V 1. Fig. 3 is a cross-section on the line 3 3 of Fig. l. I

. Our invention relates to railway appliances,

y and more particularly to railway-ties and railv fastening devices.

It is the object of our` invention toprovide -a substitute for the commonV Wooden ties, Whip/h, owing to the scarcity of suitable Wood s and their increasing cost, must give Way to an We have devised article 'cheaper to maintain.- a tie which is not only cheaper, but'one which is practically indestructible. Our tie, being thoroughly Waterproofed, is [ireproof in all its material parts, will not be affected by frost or Water, and the parts are so strongly united that they will not become broken or separated.

lVe also give the rails asuitable elastic bed vwhich not only makes the trains less noisy and less injurious to the rollingstock, but also prevents to a largedegree the pounding action on' the car-Wheels from being transmitted so suddenly to the concrete portion of the ties, the result beingthat said ties will not become cracked or broken.

Referring to the drawings, A represents the tie as aWhole, having, preferably, a rectangular'base, the sides and ends tapering up- Wardly, so that the top has a somewhat less area than the base, thus increasing the bed or bearing-Surface of the tie. The inclined sides and ends, either being regarded as a laterall surface, enable the tie to take hold of the ballast better than if they Were vertical, because the ballast on this portion transmits its Weight tothe tie and locks same securely in place. Any movement of the tie Will tend to lock it beneath the ballast, the bottom edge acting like a plow-point or a cultivator-tooth. If

lwith holesb.

plate against movement in the tie and also.

plate has a number of holes through it, so

that the concrete will run through them and lock the plate tightly in place Within the concrete and unite the concrete together along the plane occupied by the plate. If the holes Were not made,`the portions of the concrete on opposite sides of the plate would have a large area entirely separated, and there would `thus be lines and planes of Weakness next to the plate, where the concrete might become broken; but when the holes are made the coni crete binds together through the holes a large portion of the said llines and planes and becomes one solid mass.

The steel channel-plate B extends nearly the full length of the tie and has doWnWardlybent lateral portions or flanges Z2', provided with outwardly-extending iianges or feet Z22. The` flanges Z2' of the plate B are provided The flanges and b2 stifen the provide a series of holes B in a plurality of planes, so that the strain on one portion of the plate Will not be transmitted so largely to allother parts. Y

Riveted to or other wise secured to the channel-plate B are angle-plates Gr, each having a vertical portion or .tongue standing up parallel With therail E and slightly above the top of the rail-flange.

Lying in the concrete tie Vand iiushvvith its upper surface is asteel plate Q, which extends from one angle-plate G on one side of the rail to another plate Gr on the opposite side of the rail. Bolts H are passed up through the ends of the plate C and have theirheads H' locred beneath the same, as shown in Figs. 2 an 3.

Seated on the plate C is a compressed cork cushion or plate F, covered and protected With flanged steel plate on Which tie rail E lies. The cushion gives elasticity or resiliency to the solid tie construction and protects same IOO against sudden strokes, such as are given to rails by the drive-wheels oi' locomotives or heavy-loaded ears, and makes the train less noisy and to a large degree prevents injury to the trucks or rolling-stoelL Strung on each bolt H is a soft-steel clip or plate J, having one end on the upper end of an angle-plate Gr and the other end on the bottom flange of the rail. A nut on each bolt H is screwed down on each elipvto hold the rail securely on the tie.

The concrete we prefer to use is made of crushed slag, sand, and cement; but we do not desire to be limited to this composition, as other plastic hardening Compositions may be used.

Having described our invention, we claim- 1. In a railway-tie, a plastic material having embedded therein a perforated U-shaped plate of metal extending longitudinally of the tie continuously between the rails, the sides of the U-shaped plate extending downwardly.

a raillange and one of said tongues, bolts secured by said bed-plate, and means on the bolts for holding the clips in place.

Signed at Pittsburg, Pennsylvania., this 3d day of June, 1903.
