Specification of Letters Patent.

Application filed September 3, 1912. Serial No. 718,264.

To all whom, t may concern.'

`the principal object is to provide such a concrete structure with a reinforcement of great strength combined with rail securing means incorporated with and forming a part of the reinforcement.

It is a further object to provide longitudinal reinforcing` bars and spacing bars which are also adapted to form rigid transverse supports for the longitudinal bars.

In the drawings accompanying this speciiication and forming therewith the application for Letters Patent: Figure 1 is a side elevation of a cross tie adapted for railroad use, the cementitious material being shown in section, and the reinforcing means in elevation. Fig. 2 is a cross section of the tie on the line 2-2 of Fig. 1, looking in the direction of the arrows. Fig. S is a similar cross section on the line 3-3 of Fig. 1, clearly showing the rail fastener and its socket. Fig. t is a sectional detail giving two different end elevations of the sockets. Fig. 5 is a detail perspective view of the modification of the transverse spacing bar.

More specically like numerals indicate similar parts in the different views of the drawings, 6 designating the body of cementitious material of the tie molded around the reinforcing member 7, this latter being entirely inclosed within the cementitious material and protected thereby from deterioration common to metallic structures.

This reinforcement is shown of general rectangular cross section, being composed of four angle irons 8 spaced in regular form by means of a plurality of spacing bars 9. These spacing bars, also preferably formed of iron as are theangle bars 8, are formed of o-ne piece of flat or strap metal, which are cut away at their ends leaving shoulders on the straps equal to the distance it is desired to space the anglebars, the material incloscf by these shoulders being preferably formed up at right angles to the flat surface to form a channel portion 10, the inner face of the angle irons resting against the shoulders on the ends of these flanges, the extended end beyond these shoulders being formed over the other web of the angle bar. If it is desired to prevent lateral or sliding movement. of the bar, a rivet or bolt 11 is passed through the three thicknesses of the material rigidly securing the two angle bars in relation to the spacing bars or straps. A pair of these reinforcing elements with the webs of the angles facing outward are joined to form the general rectangular truss or frame 7 by transverse spacing bars 12 built of corresponding form to the bars 9, shown as occupying a vertical position in the tie while the latter bars 12 occupy a horizontal position. Similar bo-lts 11 secure these horizontal transverse spacing bars in rigid relation and in close contact with the vertical spacing bars 9, previously described.

A modified forni of the spacing bar using channeled stock is shown in Fig. 5, the flanges being merely cut into at the points 13 equal to the distance at which it is desired to support the longitudinal beams in the structure, the sides being drawn down beyond these cuts to form the outer eXtension 14, being of greater width than the channel 10 and is carried over the webs of the angle beams, as described before. To further bind the reinforcing member in rigid relation and provide greater strength and rigidity, the wire 15 is wound around the structure previous to its insertion into the form where a suflicient quantity of cementitious material has been placed to provide for the interval from the lower part of the reinforcement to the exterior surface of the tie.

Previous to the introduction of the reinforcing member into the mold the spike retaining sockets 17 are secured in position at the proper intervals, these being preferably formed of a flattened tube, the greater diameter of the tube extending parallel with the rail or transversely to the tie.

The upper ends of these sockets extend to the upper face of the tie, the lower edges being provided with the transverse flanges 18 and 19, the flanges 18 being adapted to be folded upon a web of one of the angle bars, thus tying the socket rigidly in the structure. r)The liange 19 is disposedi horizontally inward and in the winding of the wire 15 a section is preferably brought in contactwith the latter flange and serves as a support for the socket While the molding or the tamping is being performed. l

The socket is provided with a slot 20 which engages and registers with the tongue 2l on the spike 22. A second slot 23 is cut in the socket and is adapted to engage the hook 24 formed on the lower end of the locking strap 25. After the spike has been introduced into t-he socket and the locking strip 25 the key 26 is driven between the two latter members of the securing means for'cing thespike in rigid frictional contact with the portion of the socket adjacent to it. The k'ey 26 is of such form, provided with a lifting lug, that the tops of the key and spike will register and be adapted to be held in this position by the 'turned over portion 28 of the locking strip 25. I

Just 'previous to the final operation in formin-g the tie and 'completing the tamping, an asbestos plate is located transversely in the cementitious material between the adjacent sockets to form the non-conducting, non-corroding and elastic support for the railroad rail 31, as clearly shown in Figs. l and 4. Suitable plugs are placed in the i sockets at either end While t-he tie is being forme'd and the slots in the sockets may be formed' as indentati'ons therein, or provided with suitable housings to prevent the cementitious material from filling' the latter during the process of molding the tie.

IV hat I claim is:

l. A c'oiicr'ete tie, comprising a plurality of longitudinally disposed embedded angle be'ams the legs of said angle beams projecting outwardly toward the surfaces of the tie structure, spacing means for holding said angle beams in parallelrelati'on, means to secure each anfgle beam to the spacing means, and a metallic winding on the periphery of the structure.

2. A concrete tie, comprising a plurality of longitudinally disposed parallel angle bars, spacing straps formed with channeled sections intermediate their engagelnent with said angle bars, and means for securing said angle bars in contact with the edges of said channeled spacing straps.

3. A Aconcrete tie, comprising a series of longitudinally disposed parallel angle bars, spacing straps formed With channeled faces intermediate their engagement with said angle bars, a series 'of spacing straps forming a rectangular frame with said angle bars, rigid relation to said spacing bars.

4.,A concrete tie, comprising a longitudinal body of concrete, a series of longitudinally disposed angle bars supported in said concrete, spacing straps transversely disposed in relation to said angle bars and equally placed therein, clamping means to secure said bars in rigid relation tosaid straps, a wire binding to reinforce and embrace said bars and straps, metallic sockets embedded in said concrete to receive rail locking means, and an asbestos cushion interposed in a recess intermediate a pair of saidsocketsto form a non-corroding bearing for the rails supported by said tie. c

5. A concrete tie, comprising acplu-rality of longitudinally disposed embedded angle beams, the legs of said angle beams projecting outwardly toward the surfaces lof the tie structure, and a metallic winding embracing the embed'dedangle beams.

6. A concrete tie, comprising aplurality of longitudinally disposed embedded angle beams, the legs of said angle' beams project ing outwardly toward the surfaces of t-he tie structure, a metallic winding 'embracing the yembedded angle beams, and metall-ic sockets embedded in the tie st'ructure to receive a rail-locking means.

' In Witness that I claim the foregoing I have hereunto lsubscribed my name this 27th day of August, 1912. j
