1 This invention relates to improvements in railway ties vand has particular'reference to an internally reenforced concrete tie. i The principal object of the present invention is thev provision of a concrete railway ltie internally reen-forced by va unitary fabricated rod structure. Another object of the 'invention is theprovision lof a non-metallic railway tie reenforcedy by a unitary skeleton of lrigid-ly fabricated metallic A further object of the invention 'is 'thev provision of a 'railway tie rnade of a plastic compound reenforced by a plurality 'of interconnected crossedloops of metal/rods. 1-

Another object-is the provision of "a concrete tie having 'embedded'-bolt-sockets accessible from above Afor quick insertion of the headyof the rail securing bolt. Astill further Aobject isthev provision of an internally reenforced Vl.concrete tie v having side pockets.

Other objects are sturdiness and economy of construction, emciency and 'ease of operation and -llptability for .receiving rails ofdifferentsizes.

With these objects in "View, Vas wellas .-other objects which willappear during the course of the specification, reference will be had to the drawings, wherein: y v"Mgnre i is va plan'viewr-of'a railway tiel-erna Ibodyirrg vthis invention.

Throughout the several views like reference characters refer to similar parts and the numeral l2 is the rail tie body member constructed of a plastic compound such as concrete of substantially rectangular cross sectional form. The top I4 and base I6 of the tie are disposed in parallel planar relation to serve respectively as bearings for the rails and a bearing for supporting the tie on the railroad bed. The tie or body member is .i claim. (C1. 23e-.e057

recessed'at its opposite ends and at Vits opposite sides at i8.-` The lcentral portion of the tie is recessed inwardly-from its opposite sides iat 28; The inner portions of recesses 2B are spaced aj-partto present a supporting fer-ib 22. The adjacent ends-of recesses I8 and '20 are spaced apart to present a solid -tie portieriY 24to vprovide a suitable `tiefsecti'on for `the reception lof the rails.

Referring Ito Fig. 1 wherein therecesses I3 and 21B are shown in dotted lines, it will -be rnoted :that the body niember'is-symmetrical inform. Furthermore, the-recessesare made withv arcuate approaches to Ikthe side walls, thus :precluding obectionable corners. The vformation of these recesses -do not interfere substantially `with the strength of the-tie 'but -do eliminate considerable material `to lessenfits weight; Embedded .the solid tie portion which-is lther-ail Ibearingfarea, 'is a pair -of spaced apart Vbolt' sockets 25 of `substantially rectangular -cross section with a slot 28 formedl in the upper side Ythereof vto present ledges f3il'ito receive the head 32 of the bo'lt 3l. The upperlsurf-a'ce fof fthe bolt :socket is :transversely notched at 36. A recess 38 formed :inthe tie at one end of the bolt socket is of fsuflicient sizefto receive the head of 'the bolt :therein where by it may-be moved finto the iboltlsocket as shown in Fig. '10." Integral with the bottom Wall -of the boltfsocketfis a pair of anchor lbars A0 which diverge l'downwardly V'and -are :each provided with outwardlyturned end portions 42. These anchor bars vare of -suiiicient length to properly anchor the bolt socket 'in the r`concrete tie. The rail Il extends transversely of `the tie as vshown in 1Fig.v-'2, and -is secured inoperative relation rvby `mea-neef rail `clips d6 which are secured lin the 1operative position by bolts 3l and nuts I8 which are pro vided with spring washers 50. This lrail clip Vis provided 'atits'base'with'fa depending rib 52 adjacent its vouter edge to engage the transverse notches "formed 'in the 'bolt socket, vvthus'preven'ting movement of the bolt and clip longitudinally of the tie. This longitudinal adjustment of the railway clip relative to the tie provides a securing means for rails of different sizes.

It is found advisable to spread a coat of red lead over that portion of the top of the tie contacted by the rail. This serves as a cushion to overcome the natural hardness of the cement structure.

The interior reenforcing structure or skeleton 54. best shown in Fig. 7, and in dotted lines in Figs. l and 2, serves to reenforce the concrete by adding tensile strength to the upper portion of the `tie and compression strength to the lower disposed bars 60 which are in the Vertical central i plane of the tie. The lower loop member 8 provided at its central portion with a cross tie bar 62 and the loop 56 is provided with 'crosstie .bars 64 directly beneath the points of application of the loads. A verticallydisposed reenfoic- :ing member 66 positioned in the vertical central.

plane of the tie is provided with end sections 68 joined togeth er at their top; sides byrf a rod 1,0 disposed in theplane otheclosed loop 55. End :sections comprisea base rod ]2 joined atits inner .f end by upwardly and; inwardly inclined rods $14 to rod 10 and toa rod 16 by means o f upwardly and outwardly 1 extending rods 18. It will .be noted by referring to Fig. 2 ,thaft :these end Vsections are s oV related tothefline of application o f ythe load that they, are equidistant at Vopposite sides of said load and serve tostrengthen lthe tie structure Vagainst the'shearing action Aof the load. :The rod A16 is .interconnected with the, end bars 88 Vof the upper loop 56. These rods forming the skeleton 5,4 are bent where convenient te change the direction and vare Aproperly welded at the points of joining soasvigtoupresentan integral structurefwhich may, be properly. positioned. in, the-moldwhenftheplastic material Y1S pouredt No part of this reeniorcing structure is exposed lout is suicientlyembeddedlin theconcrete'to insure proper ,functioningto reenforce'the tie against tensile, compression and shearing vac -v tion y set upin theitie during the usual application ofthe load.

,Referring to Figs. fl and 5, it will be notedthat in Fig. e1, there are .three barsgadiacent thebotf tom andtwo barsadjacentthetop and that this sectioniis taken, adjacent theiline, ,ci application of ithe load, .thustaking care of-the tensile pulljin the--topjportion'of rthe-tie; also theshearing ac; tion of theload Ais decreased by the oblique bars 74- and 1 8 which,di stribute the load to tl1e `tie at pointsjrernovedfrom thebearing vsurface gf the rail.; Eurthermore, the longitudinal central portionof the tie ,'is'subjected tol a greater. tensile pullV adjacent its top and is, therefore, reenforced by. thev longitudnalzbarsZ 0f loop' 56 and the Y centralied 'H'Lv The gross tie bars B gqandll serve to maintain the elongated 1Qops in proper relative relation during the process oiconstruction Qt Vthe Vtie These rods termine the. ,reenforcing structure are shown in the enlarged views as square in cross section. This form of rod I lends itself to the Welding of the rods andalso insures a better bond between the rods and the cement structure. However, it is quite apparent that other shapes of rods might be used with good eiect.

' The function of the recesses I8 and 20 is to lessen the weight of the tie without materially oisetting its strength and at the sanneV time pro viding means whereby theties vare more'securel-y anchored in the road bedf This internally reenforced railway' tie is re# latively light, is long-lived, is reenforced to 'properly distribute the rail loads throughout the entire base of the tie, and when properly set in the road bed will'not buckle and crack.

` What I claim as new and desire to protect by Letters Patent is:

A concrete railway tie comprising an elongatedbody member having'recesses formed in its sidewalls and having spa ce d apart solid rail receiving sections; horizontally disposed elongated reenforcing loops embedded in parallel relation in the upper and lower portions respectively'of said body member; vertically disposed tiebars joining together the adjacent end portionsof. said loops;V an undulated reenforcing-fplanar member disposed -in the verticalcentral plane of said reenforcedbodymernber having V-shaped depressions at said solid rail receiving sections and :beine V111-1111;!domed at its. ends t0 the Opposite end; ysections of said h o rizontally2disposed 'loc'gzns-J andtransverse :tie bar s joining togetherL the longitudinal side wiresfof sai d upper loop at said rail receiving section, said reinforcing member being disposed in the upperpciftion @f saidf tie intermediate thea rail receiving portio n s thereof, anclj in the lowerportion ci said tie at saidlal receiving portions.v Y e 1 Y is, Raststtten@ f The-following references are .:of. .record inthe file of lthis-patent: v1 f 1 f ,i f
