STATES LOUISE. BOTTO, OF SAN ANTONIO, TEXAS,

RAILROAD TIE.

Application filed March 26, 1928.

This invention involves improvements in *ailroad-ties and the object of this inven tion is to produce a railroad-tie composed of several metal sections and concrete or some other cementing material, combined in such a way that it can be fabricated in place under the railroad rails if desired, into a railroad tie more economical in first cost, maintenance, and replacement, and rendering the same service now obtained lrom wood ties, composition, or fabricated ties.

ll ith the foregoing, and other objects in view which will appear in the following description, and with the understanding that the invention lies in the uses of the component parts and not in the particular embodiment herein disclosed, and that changes may be made in this particular embodiment without departingd'ron'i the spirit of the invention One embodiment of my invention is illustrated in the accompanying drawings in which Figure 1 is a perspective view of my improved tie showing angle iron brace members,

Figure 2 is an end view,

Figure 8 is a section taken on line 3-3 of Figure l,

Eigured is a plan view,

Figure 5 is a side elevation,

Figure (3 is a perspective view showing tie with cross plates on which railsrest, and

Figure '7 is a View of the reinforcing wire.

The railroac btie shown is constructed of two rail sections, 1, out to the proper length and laid parallel and in the same plane, with the proper distance between the adjacent of the bases of the rails. This distance varies with the weight and sec tions of the metal members and the strength or": the reinforcing wire and the concrete or cement mat al used, and in all cases is the maximum allowable distance, taking into cmsioeration proper factors of safety t with permanent ermstruction. in sp -1al cares, of course, this distance can be made than that set out in the preceding sentence.

Likewise any suitable metal member can be used in place of the rail sections, 1, as shown.

The purpose of this maximum spacing is to obtain the greatest width of tiepossible with the materials used, so that a maximum bearing surface is obtained, thereby decreas- Serial No. 264,713.

ing the number of ties necessary to meet certain road bed conditions to a minimum. This is one of the salient features oi? this invention.

The bracingmembers, 2, are next cut to such a length as to extend across the whole width of the tie. Angle iron as shown in Figs. 1 to 5 inclusive, may be employed for this purpose, or flat plates of suitable dimensions may be used. Likewise plates 3 placed. above sections, 1., to lie directly under the base oi the railroad rail crossing the tie, as shown in Fig. 6, may be used instead of the angle iron as shown in the other figures. These members are welded to the sections, 1, as shown, in sullicient places to attain the strength desired. If it is deemed necessary, holes may be burned into the members, 2, as shown at i, before these members are put in place, and then welded to the sections, 1, through these holes also.

The reinforcing; wire, 5, and shown in de tail in Fig. 7, is placed as shown at" in Fig. 3. The position or actual type of reinforcing steel used may be changed .to obtain the maximum strength for the use intended. The purpose of this reinforcing steel is to increase the strength of the concrete or cement material, 6, which is poured between the sections, 1, as shown.

litter the sections, 1, and 2, are in position in the road-bed and properly aligned, and. the railroad rails are laid thereon, the her are drilled or burned as shown, if stance clips bolted on are desired to fasten the rails to the cross-ties. However, instead of bolting the clips in place, these some c ips may be welded to the top of the sect-ire 1. The idea of welding the clips to the tie is claimed as new and novel, and

inchided one of the features of this invcnti on.

nother important feature, which is mied'arul included as part 01": this inveniion, is the fact that all the elements used in the construction of this tie may be brought to the place, where the tie is to be used, separately, and made into the proper dimensions and assembled in place in the roadbed, allowing the concrete or a cement-like material to be poured from the top after it is in position, and eliminating all heavy railroad-ties.

This feature permits these ties to be made these pie up in any lengths desired, even for switches, and double track'construction, and still be practicable.

Another feature of this invention is brought out in the case Where steel plates 3 are used to weld the two parallel sections, 1, together. These plates may be placed so that their centers are under the center of the railroad rail crossing. In this event also serve as tie plates. Tie

plates are not used with the other forms of this tier I Having described my invention, what I claim as new and novel, and desire to se cure by Letters Patent, is

A fabricated railroad cross-tie comprising two sections of track rails in spaced parallel relation to each other, said sections being inverted and having their normally lower *idc base flanges uppermost and their normally upper narrow Wheel engaging flanges lowermost, rail supporting plates Welded to the upper side of said uppermost flanges, angle irons comprising horizontal and vertical walls positioned at opposite ends of said sections, said horizontal walls of said angle irons extending across and contacting with the tops of said sections so as to lie above said sections, said vertical walls of i d angle irons extending across and contacting the ends 0t said sections, both the d horizontal and vertical Walls of ture.
