TRACK-BED CONSTRUCTIOIT AND ARRANGEMENT.

Application filed December This invention relates to railway track and track bed construction and arrangement, and comprises a continuous `support for track rails composed of ties made troni any chosen materia-l, plastic, wood, stone or metal having special torination and disposition for the purpose ot increasii'ig the load resisting qualities of the bed and rails in order to withstand the material present increaseot' the weight of rolling stock and the probable continued additions to the saine in tuture.

Another object of this invention and a feature of the construction hereinbelow set forth is the making ot the road-bed water-` proof, by shedding the water to both sides ot'y the track in order lio prevent the water, snow or sleet 'troni seeping through top7 sides and under thev foundation o'l the roadn bed and softening up the supporting grouinl or earth 0f theeinbanlnnent 'thereby permitting the ties to sink and destroy the desired track level, and calling for repeated repairs.

Another object of: this invention is to provide a rail bed inade up of `a plurality ot ties, sills or bases, placed side by side closely or touching each other and making a unitorin, continuous supporting hase for the track.

Another object or" this invention isthe production of a rail bed of the character stated composed ot associated individual ineinbers which may be termed tics, sills or bases. of the special formation shown and dttribed, and laving the proper proportions as to thickness, length and width designed to withstand the great loads, pressures and impacts pounding thereon during heavy service. v y

Another object of this invention lthe provision ot' a` bed nieniber ot the fashion and material set forth herein and adapted to receive an under-rail support, or'to be used without such support. Under certain circumstances the under-rail is ot very great advantage in inany ways, as itgives `additional support to each meinberacting as a carrier beain longitudinally beneath the track rails.

Another object of' thisV invention is the construction of a `track rails support or tie liaving a recessed under surface whereby the ballastis held at the ends of the ties, and

forced by the pressure of the tratlic into contact withv the ties and prevented from displacement and spreading.

Another lobject of this invention the formation ot ties eachI having a narrower' end and a wider end wliereby they may be laideach tie reversed in position with respect to the adjoining tie to forni a straight track bed, or placed in the saine way to rtorni curved portions oi the roadway.

With the above and other objects following lro'in them, this invention consists of certain original features ot' construction and arrangement as described in Vthe following explanation of the structure and operation, and as illustrated in the accompanying drawings showing the preferred torni.

Utthe drawings Figure l represents a top plan View ot two `ties constructed in accordance with this invention, and arranged side by side in contact. ',lhe vtrack rails are omitted. n Y

vFigure 2 is an end view of such associated ties, partly vin section Ato disclose the curving recess formed in the bottoni of each tie near its end. p Figure 3 is a bottoni plan view ot the two inenibers or ties illustrated in Figure l, and shows the formation of the underlying portions o't' 'the ties. j

Figure t is a cross section of one oi" the tieson the broken line t-fl; of Figure 3, showing also in section the reinforcing clekments embedded in the material otfwhich the tie is niade.- i y l `igure 5 is a. vertical transverse ysection ot theroadbed and rail pillow members. This section is taken between the ties, and illustrates the under-rails in section.

Figure 6 isa section of the roadbed` similar to Figure 5, but the section extends longitudinally through the tie and discloses the reinforcing eleinents therein. rhe rails, tie plates and pillow inenibersyare shown in section.

Figure is a perspective view forcing elements placed lengthwise in each tie. One ot. the side wooden` bars which augment the elastical stiffness and deadeningy .of the rein-v straight direction and also more or less curved or ollset with respect to the original or normal line of the rails.

Figure 9 is a side view of the end of one of the ties, and shows an additional water .shed at the side of the track whereby the water is led entirely away Vfrom the bed of the rails and caused to flow downwardly and outwardly at the side of the ballast or filling. c

Throughout the description and drawings the same part is referred to by the same number. i

Considering the drawings, the tie, base or sill member constituting the track rails support is referred to generally by the numeral 1. As illustrated in Figure S, the members 1 each have a narrower end 2 and a wider end 3, and the sides of the members are thus inclined to each other. By reason of this formation the track bed may be laid either for a straight track by reversing the positions of the members with respect to each other, or by placing themside by side in the same relative positions the track may be extended in a curving direction. On its upper surface it has a middle flat portion 4 adapted to carry the track rails 5. The flat portion or track rails carrying portion occupies the middle of the length and width of the member l, and on either side thereof sloping from a middle line both ways to the end of the member are the water shedding inclines 6, 7, 8, 9. It will be noted in Figures l, 2, et and 5 that the water shedding inclines slope away from the tlat portion el transversely as well as longitudinally. The purpose is to direct all the surface water ofi' the ends of the melnbers 1, and in Figure 9 an additional water shed l() is illustrated. The form and position of this additional part is in no sense limited to the shape set ont in the drawings. Asbest shown in Figures 1, 2 'and 4, the water shedding inclines at the sides of the fiat portion 1 are bounded lengthwise by raised edges or beads 1l. It will be observed further in the Figures 2 and 4 that the vertically disposed side portions of thefmcmber l designated by reference number 12 and leading downwardly from the beads 11 are formed outwardly curving with a swell or slight oval in order that the pressure will not break oif the beads or upstanding portions.

Attention is Vdirected particularly to Figures 2 and 4 wherein it will be seen thatthe continuations 13 of the side walls of the member 1 slant downwardly and inwardly on either side at the end portions of the member. This formation results in the side recesses 14, and it will be observed that the top portion or surfaces of the recesses 14 marked 15 slant upwardly and towards the middle of the member 1 the inner limits of the recesses being the transverse solid portion 16 of which the lower side of cach membcr is provided with two, spaced apart in correspondence with the width of the track, and usually joined by a longitudinal solid portion 17 as best shown in Figure 3. tween the side end recesses 14 at the ends of the member 1 are formed the dishcd deprcs sions 1S. The depressions or hollows lta' arc best shown in Figures 2, and (5. These depressions or concave bottoms 1&5 at each end of the member 1, beginning at the ends and back to the bearing portion where the member rests on the undera'ails 19, have rounded corners on the bottom and rounded corners on the outside edges, .so that when the tamping is done the ballast or lill can be forced easily underneath, and rolled back into the hollow or rounding portion in a hump, and when once tampcd in place and the pressure of the trailic put on, the till cannot come out, because of the concave part of the tie hugging over the ballast and the fill in the pockets or depressions described.

As stated above the solid transverse portions 16 of the member 1 are spaced apart as illustrated in Figure 3, and between them on either side of the longitlulinal solid bar shaped joining portion 17, are two part recesses 2U and 21. Each of tinl reci-cs 2() and 21 is provided with a surface slanting upwardly and towards one of the transverse solid portions, so that when pressure is put on the top center the ballast or filling will be forced outward and upward and back against the transverse solid portions or shoulders 16.

Considering Figures it, (3 and 7. the reinforcing elements of this invention will be understood. Such elements comprise side truss rods 22 and 23 connected at separated points by cross bars 24. The truss rods are enclosed in a tubular netted opcnwork wire or metal device which has an upper tial portion 26. a lower flat portion 27, and ouiwardly pointed angular side portions 2H and 29 joining the upper and lower fiat pori ions. In addition lo these parts [here are urinalij.' introduced the deadening or stitl'ening'bars 3() of wood or other selected materials. )liso rod 32 arranged below and extending ilul full length of said cover 25. iv'hile the particular reinforcing elements just described embody the preferred forms for use with this invention. it is not intended in any .sense to limit the construction to those forms.

In explanation of the operation of this invention, attention is directed to Figures 2. 3, 4, 5 and 6. The under rails 19 are ar-Y ranged with suitable tie plates 31 on top of the rails beneath and against the transverse solid portions 1G, and the members 1 are placed side by side usually in contact. As illustrated in Figures 3 and l the side relfl and 2l of adjoining members mme together and form pockets with their upper bfi loo

lio

`also serve to receive and to hold the ballast in place at the ends of the members. It is held to be ywithin the purview of this invention |`to suitably calk the space between the beads 11 ot' adjoining members 1 with any selected substance or cement. It is believed to be now clear that I have described a continuous track bed which by reason ot the forms of the supporting` members 1 may be laid in a straight line or in a curving direction, and ythat all the surface water will be shed at the ends of the ties, and the ballast held in place against `the movement in any direction by reason of the trattie pounding however heavy it may be.

To relieve the stress at centre of tie, and also serve as additional deadening means, clay or the like is interposed between the under-rail`s 19, so that the ballast surrounds the bottom and sides of the clay liller.
