LEWIS KIDD, 0F INDIANAPOLIS, INDIANA.

REINFORCED-CONCRET RAILWAY-TIE Application led April 9, 191'?.

To all Lv/wm t may concern:

Be it known that I, Lnwis KIDD, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Reinforced-Concrete Railway-Ties, of which the following is a specification.

This invention relates to improvements in railway ties, more particularly tothe class of reinforced concrete ties, and has for one of its objects to improve the construction and increase the efficiency and utility of devices of this character.

Another object of the invention is to provide a device of this character combining a supporting tie and means for supporting the rail upon the tie.

With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the inventionn Figure 1 is a side elevation partly in section of a tie constructed in accordance with the invention;

Fig. 2 is a transverse section on the line 2-2 of Fig. 1.

Fig. 3 is a detached perspective view of a portion of the reinforcing member.

Fig. 4 is a detached perspective view of one of the rail supporting plates.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device comprises a body 10 of concrete, of the usual size of a railway tie, or about 8 feet long, 6 inches high and 8 inches wide, but these proportions may be varied as required. Embedded within the body 10 of the tie and extending longitudinally thereof is a metal plate represented as a whole at 11, and provided with a plurality of transverse apertures 12 spaced at uniform distances apart. Located upon the upper face of the tie at the points where the rails, represented at 13, are to be located, are bearing plates 14 of metal, of sufficient size and Specification of Letters Patent.

thickness to bear the strains to which they will be subjected, these plates being generally about 8 inches square and inch thick.

Rising from the reinforcing member 11 are rail holding members 15, four being employed for each of the rail supporting plates 14. The members 14 are perforated as shown in Fig. 4, to receive the holding members 15, which thus project initially above the flanges of the rails 13, as shown at the left of Fig. 1. The members 11-15 are integral, and preferably formed of malleable iron or the like, so that the projecting ends of the supporting members 15 may be bent over the flanges of the rails after the latter are located in position upon the plates 14, as shown at the right in Fig. 1. By this means the members 15 serve the same purpose as the ordinary spikes employed for holding` rails to the ties, and provide an effectual means for supporting the rails in position and preventing both lateral and vertical displacement of the rails.

The member 11 together with its aper tures 12 is embedded within the body 10 of the tie when the latter is molded and the concrete material will enter the apertures 12 when poured into the mold, and thus iirmly anchor the member 11 in position. The supporting members 15 likewise assist in holding the member 11 in place when the cementitious material is poured around them.

The improved device is simple in construction, can be expeditiously manufactured and is durable and impervious to moisture and not liable to be affected by extremes of either heat or cold.

Having thus described the invention, what is claimed as new is:

1. A railway tie comprising a body of concrete material, a longitudinally directed core plate embedded in the tie material and entirely inclosed thereby, and rail engaging members extending transversely from op* posite sides of the core plate and thence upwardly above the upper line of the body, said upwardly extended portions adapted to be bent over the flanges of a rail when disposed above the body.

2. A railway tie comprising a body of concrete material, a longitudinally directed core plate embedded in the tie material and entirely inelosed thereby, rail engaging f members extending transversely from opposite sides of the core plate and thence up- Wardly above the upper line of the body, a

In testimony whereof I affix my signature.
