' In carrymgthis invention into practicet-he 1 roadbed or foundation of the railway track is congmsed of longitudinal composite.stringers A: 7

adapted to support the rails Cof the track, see Figs. .1 and 2. The composite stringers are bankeebwith any suitable filling materialto produce an embankment D, and between the rails of the track this embankment may be constructed or fashioned in order to provide a longitudinal gulley or gutter (1'. From this'gutter are adapted to extend transverse drains E,,.the latter running below one of the stringers and discharging the water from the gulley at. any desired place away from the'track.

For economy inccnstruction and installation, the com ositestringers A, B, are sepaonly joined by the filling material which constitutes the embankment D; Each composite stringer consists of concrete, or similar lmaterial a, and metal b,for reinforcing said. concrete, thus'producing what I term ablebodied concrete. In cross section the rate 'or insta ed individually, that is,f they have no common connection, and they are stringer Azor B may have'any'suitable oridesired contour, one form of said stringer being I may employ any suitable construction or arrangement of metal to form-v the internal strengthening member of the stringer, but, in. one embodiment of said in-a verition," this metallic strengthening elements is in the form of a skeleton framework, the

same beingshown by Figs. 3 and 4, as consisting of a frameworkwhich 1s tr angular in cross-sect ongand Y composed of parts: -Wll10ll 1 are joined bylicoupling pieces. It is to be unt derstood-,;h0tvever, that the invention isnot restricted to any particular or detailed -constructiofl of the metal reinforcing member, but it'is believed that the particular form of the triangular skeleton framework is -espe- 'chair section has a longitudinal noted that the rail rests squarely or l may be employed, as the chanical eouivalents one for the other. After cially useful in the construction of the cornposite stringer. The base portion of the triangular framework is at the bottom of the stringer, and said framework has, at its apex,

'a longitudinal runner 1;, adapted for the reception of a plurality of chairs Fforsupporting the rail 0.

Each chair F consists of the members or sections f, f-, one of which is shown more clearly by Figs. 6 and 7 The inner portion of the chair section is rovided with a transverse groove -f and elow this groove the passage or opening f The chairsectionis, furthermore, provided with a longitudinal slot j", the same being approximately T-sha'ped in cross-section, and. opening through the upper face of the chair. A recess f is provided on said upper face of the chair, said recess forming shoulders f s In the installation of the track, the members), f, of each chair are fitted to the runher I) of the metallic framework 6, so that the groovesf of said brace the aforesaid runner l). Thehections of the chair are clamped firmly on the runner I) by a bolt G, which passes through the passages f of said chair, and on the end ortions of this bolt are screwed the nuts g, t. is latter binding against the chair sections and clamping them firmly on said runner b.

It will be understood that a suitable num ber of chairs F are attached to the runner b of each' framework forming a part of eachv stringer, said chairs being spaced at proper intervals on the aforesaid runner b, and said chairs being partly exposed above the con crete material. a, for the proper reception of the rail C.

By reference to Figs. 3 and i, it will be upon the chairs and upon the concrete material a, in the intervals between the chairs, thus afford ing a permanent and substantial foundation for the rail.

' Any suitable means for holding the rail on the chairs maybe employed, and in Figs. 8 and 9, I have shown different constructions of rail clamping devices. In Fig. 8a wedge;

shaped or tapered plate His employed, said plate having, at its lower rear end, an'oifset or flange h, and said plate having a slot h,

V which opens through one end of the clamp,

thereby producmg what I term a bifurcated wedge or claw. In Fig. 9, another form of tlieclamp is. represented at I, said clamp censisting of a tapering or wedge-shaped plate having a heelor flange "i, and a slot i. It will be noted that either of these clamps, H

"are the methefrail sheillhavebeen-laid on the chairs, the clamps-are fitted'to said chairs and adjusted to engage with thebaseflange of the rail on the respective sides tliereoli, and then the chair sections will sin-- clamps are secured in position by the bolts J, the headsof said bolts being received in the slots f of the sections of the chair. The nuts 1' may be ti htened on the bolts to force the clamps tightly into engagement with the rail.

If desired, after the clamps have been. placed in position, so that the heels'thereof occupy the recesses of the chairs, the bolts may then be ti htened,,and thereafter the clamps may be riv eninto. lace for the purpose of tightly clamping 't erail 11 on the chairs. It will be understoodthatt e heels of the clamps fit in 'the' recesses of the chairs, so that the shoulder f wil revent the clamps from. moving outwar y and away from the rail.

In installing a track in accordance with this invention one mode of procedure is as follows :--The grade being established, I spread a layer of suitable material, such as cement concrete; in suitable pro )ortions below the position to be assumed by each rail of the t rack.- On this layer, and in correct position, the framework is placed, and another layer or charge of cement is then dumped upon the first layer'so as to surround or envelop, substantially, the skeleton framework. -On this layer a plank or board is placed on each side of the embryo stringer so as do constitute a temporary form for the concrete material, thus enabling me to resume and complete the operation of installing the concrete matcrialfor the stringer. The concrete material is leveled off and accurately finished so as to produce the permanent longitudinal composite stringer, and, at the proper time, the chairs F are fitted or applied to the memberbof the framework. As the top portion of the concrete material forming a part of each stringer is intended to be somewhat above the upper sustaining member I) of the skeleton framework, I employ temporary twin blocks (not shown) which are the exact counterpartof the chairs, said ten'iporarjr twin. blocks being set in the cement, well as fitted on the up )er portion of the cement forms soas to be ush with the top. 'lhesc temporary twin blocks are employed while the work of finishing and leveling the upper portion of the concrete is in progi less. As the concrete materials set and become hardened, the twin blocks are removed, and the inenibers'of the chair F are inserted on each side of the composite stringer, said chairs engaging with the member 3) of the skeleton framework, and being clamped firmly thereto, as heretofore described. It will be noted that the members of the chair are partly embedded or incased by concrete gnaterial of the stringer, that said chair is clamped firmly to the member 6, and that the uppor faccs or seats of the chair are substantially flush with the accurately finished top surface of the concrete material.

' Inthe embodimentof the invention shown by Figs. 19w inclusive, which: iPiesent a good substantial, constriiction. of reinforced concrete continuousdwarfed walls constitutshown, nor V o I consider]it necessaryto show, the employment of the:usualcrossftiesv in this structure. .Nevertheless, prov1s1on may be madeforsucli-ties, should conditions,

require them.. I have shown. however, in

Figs..,3, 4 and 5, oneforin of'crose tie or cross connection between adjacent chairs .011; the

parallel-stringers. Said cross-tie or cross connection may consist of a length of tubular metal K. Thiscross-tie isreceived inlthe' projectionsk' at the lower part .ofthe chairs,"

J and it is 'heldor'secured in place byiany suitable means. The cross connection is intend- 'ed to be incased or embedded permanently, as

at 7r, by concrete material,- and this concrete;

material may have any desired form in cross-' section, andit ma bemolded, or formed by. an appropriate mo d or former'which may be independent of the temporary former for the stringers, or may be employed in. conjunc tion therewith. It is evident thatthecros'stie- K may be insertedin the passages f of the chairs, in whicheventthe bolts may be omitted, and, in lieu, thereoffthe tubular '30 bolt K beemployed and another en be passed all. the way cross-ties J map .may t through the tubular cross-tie fittin'g, the said bolt being fastened with the same nuts on the outside ofthe walls a." This construction provides a completefcross tie connectionat-a very moderate cost, and itcanbe installed andprotec'ted from the weather by thecon-x crete material quite expeditiously and -'eco- From thexforegoing description taken in connection with the drawings, it will, be noted that the stringers are shown as oblong or square in cross-section forthe reason that such a form of stringer or girder is Well adapted for supporting therail-chairs, but it will be understood. that the dimensions of the string ers or girders, and the size ofthe skeleton framework, may be modified and varied as cond1t1ons may require.

In some instances where an unusually strong strmgeror girder is required, I prefer to em loy a larger skeleton framework, the sustaining members whereof may be of solid iron bars, but, in any 'event, the skeleton framework will of itself extend over fairly wide spaces and be self supporting,f while the operation of fillingin' the concrete material is being completed, so that the entire construction of the new roadbed can be perfected from'endto end with the same materials. I t

As hereinbeforeindicated, the stringers-or girders may be graded in any way familiar to, or preferred by, those skilled in railway track installation. As shown by Fig. 1, the emif bankment may consist of good heavy soil or other ballast, the space between rails can be utilized for water troughs, and said space can be well filled in and topped off with cement, as shown, so as to formsaidtroughs, or mg the com 0811361 stringers, I have not toprovide'gulleys which may be drained advantageously by the transverse drain or by any other suitable construction.-

.In and 11 of the drawings I have re resentedan embodiment of the invention w erein the composite stringer is.used in connection with a form of chair adapted for supporting a bisected and reversible rail, the latter being of the character disclosed in a I prior. application filed by me on "March 20, .1905, Serial No. 251,181 As shown, the bisected rail 0 consists of matching members which. are recessed on their inner faces and are provided at their top and bottom edges with complemental rail heads,- thus enabling the sections .or lengths of the rail to be re- .versed edge for edge, and end for end, for-the u-rpose of presenting newwearing surfaces or engagement with the wheel flanges of the rolling stock. The sections'of the chair F are recessed on their inner faces to engage with the side portions of the rail sections along-the foot flange and the webs thereof,- and these chair sections are, also, recessed on their inner faces for engagement with the stringer b of the skeleton incased frame 6.

1Tl1e chair sections are, furthermore, provided with transverse o eningsor passa es J, in which are receive the clamping bo ts G, G, whereby the sections of'thechair F may be clamped firmlv upon the member b of the framework, said bolts G, G extending through the chair sections above and be low the member b, respectively.
