7 RAILWAY-TIE.

T0 all whom it may concern: 7

Be it known that I, VILLIAM P. DAY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements inRailway-Ties, of which the following is a specification;

This invention comprehends certain new and useful improvements in railway ties, and particularly to that type of tie or rail support embodying spaced members extending transversely of the rails and ra1l supporting plates or chairs extending longitudinally beneath the rails and riveted or otherwise operatively secured to the transversely extending members.

The general object of mypresent Invention. is to provide a rail supporting structure of the character described that may be very cheaply made, that will be strong and rigid, and that will beadaptable for use in either open or closed track Work and m ballast or concrete, as desired.

A further object is toso construct the chair plates that they will be particularly well reinforced and strengthened by form.-

' ing thereon 'long'tudinallv extending lateral and downwardly extending flanges of a peculiar shape, which flanges perform the triple function of strengthening the'plate, acting to retain the ballast or'gravel beneath the plate and preventing lateral movev ment of the plates and the supporting structure as a whole. Furthermore, the peculiar shape given to these flanges and their relation to the plate is such that the flanges tend to prevent longitudinal movement of the plates. 7

Another object is to so form the members that connect the pair ofplates to'eacli other that biting edges will be provided extending transversely of the line of the rails which will grip down into the sub-soil or ballast and prevent the tie structure as a whole from creeping forward, that is, longitudinally of the rails.

A further obiect is to so construct the supporting or chair plates and the flanges thereon that ballast may be tamped beneath these chair plates but will be retainedafter being so tamped.

\Vith these and other objects in view as will more fully appear as the description proceeds, the invention consists essentially in the particular construction, arrangement Specification of Letters Patent, Pate t d M 191 Application filedJ'uly 8,1915. 'serialub.ss' 7aa and combination'of the parts as is hereinafter more fully described-and claimed.

For a full understanding of the invention and the merits thereof reference is had to the following descr ption and accompanying drawing, in which Figure 1 is a perspective vie w'of my improved rail support. Fig. 2 is a top plan view of one of the chair plates after being formed. Fig.3 is a s de elevation of thechair plate shown in Fig. 2. Figs. 4 to 7 are sections taken resoectivelv on the lines 44, 5-5, 6-6 and 77 of Fig. 2. Referring to these drawings it will be seen that my improved tie comprises a pair of angle irons 2 which are disposed in spaced relation to each other and are intended to extend transversely of the track rails; These transverselv extending. angle irons 2 are arranged with their horizontal flanges extending awavfrcm eachrother. as shown in Fig. 3,' and at their ends these angle irons 2 are riveted, bolted, or otherwise connectedto aapairpf chair plates 3 which extend lengthwise of the track and are intended to extend each beneath one" of the rails of he track. These chair platesj3 have a peculiar form which is the resultof a long course of experiments and tests'and this peculiar form s such as to give a maximum strength to the chair plateat a minimum cost in'addition to givint certainother ad antages previously referred'to. g

Each plate 3 s f steel and 'mav be from to an inch th ck. Each plat has downwardly and outwardly extending late al flanges 4. The horizontal portion of the plate is grad ally narrowedfrom its ends toward its middleor waist. and as a consef ouence the flanges 4 gradually narrow from the middle toward the ends'and when the verse members 2 to extend across the extremities of the plate and be attachedthereto by rivets of bolts 7. The plateis formed with openings 8 to receive rail engaging clamps (not shown) of any ordinary type usually used in connection with metallic -or -concrete chairs or ties. The particular means for attaching the rails to this particular rail support and tie form no part of the present .and prevent anylongitudinal movement of the tie structure. By gradually narrowing the plate 3 -toward its middle from each end and forming the inwardly bowed clownwardly and outwardly extendingflanges 4 I secure .a maximum strengthening of the plate, a much :greaterstrengthening than would occur ifthe plate had straight parallel sides with the fianges' l extending down and out from theseparallel sides and having a uniform width-along-their entire extent. 'The stampingor pressing of the plate 3-with the'flanges iacts to-warp the plate,"not in the sense thatit at all affects the flatness of the'body "of-the plate,-but only asregards the sides 4. 1b is the bowing inward of these flanges .thatlgives the requisite stiffness to the; plate and preventsthe plate from buckling orlbecoming otherwise deformed under servicecon ditions. :These Qfianges, furthermore, bite into the ballast or subsoil of the road bed andgpreventtransverseflsluing of the tie and traclr thereon andfurthermore these-flanges Willretain the ballast or {gravel that is tamped unclerthe plate'3. 7 It will be noted in Figf3wthat-when thetie isin place the lower edges iofthe flanges a extend downward in a curve,- this curwegradually rising .at each end toward the members2. Thisipermits'ballast to-be readily tamped beneath the plate -3 and yet beheld inplace thereon when'tamped.

.This form of track supporting structure has been tried in .practiceand under service conditions and has been found to possess great strength with a minimum of weight.

' It is a tie particularly adaptedrfor use in embeddedin concrete.

WV-hat is claimed is:

"1. A rail supporting structure comprisingv a pair of transversely extending spaced conmeeting. bars and ra1l supporting plates rigidly mounted upon said connecting bars and extending transversely thereto and parallel vvto the rails of atrack, eachof said plates comprising a rail'supporting plate having-a terminal portion: of aumax-i-mum width resting upon the said connecting bar's, theaplate immedately inward of said terminal: portion being gradually narrowed in widthtoward the middle of the'plate, said plate being'fiat for its entire length and "the, sidesofthe downwardly extending flanges and the lower edge of "each flange being downwardly curved'from-itsends toward its middler said flanges extending'froinone terminal; portion of the plate to theother *terminal portion. thereof and the-lower edges ofthe flanges being substantially parallel 'to'eaohi other.

of each plate being provided with oppositelydisposed downwardly and outwardly "extending flanges.
