RAILWAY-TRACK CONSTRUCTION.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed. July 13, 1910. Serial No. 572,397.

To all whom it may concern:

Be it known that I, VVmLr/tu H. CONRY, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Railway-Track Construction, of which the following is a speclfication.

This invention relates to railway track construction and has for its object the production of a sheet metal tie affording wide mil-support and ballast supported surfaces under the rails; the maximum ballast-supported surface consistent with strength out ward of the rails; and the minimum ballastsupported surface consistent with strength between the rails.

With this general object in View, the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which- Figure 1, is a plan View of a section of a railway track construction embodying my invention and showing the securing devices of adjacent ties engaging opposite sides of the rails. Fig. 2, is an enlarged section on line II II of Fig. 1. Fig. 3, is a top plan view of the construction shown in Fig. 2. Fig. 4, is an end view of the construction shown in Fig. 2, on a still larger scale. Fig. 5, is a section on the same scale as Fig. 4. on the line VV of Fig. 2. Fig. 6, is a plan view showing the rails engaged by a modified form of tie. Fig. 7 is an enlarged section on the line VII-VII of Fig. 3. Fig. 8, is a perspective view of one of the removable fastening devices. Fig. 9, is an inverted plan view of the same. Fig. 10, is a perspective View showing the threaded opening in the chair plate of the tie for engagement by the fastening device shown by Fig. 8. Fig. 11, is a perspective View showing the rail plate engaged by the fastening device. Fig. 12, is a View showing the inner edge of the rail plate, the corresponding edge of the fastening device when in engagement with the plate and a wire locking the device against rotatable movement in the rail plate.

In the said drawings where like reference characters indicate corresponding parts in all the figures, the tie, as shown is pressed out of sheet metal, the side walls 1 being formed on curves whose radii constantly change, by preference, in such a manner as to resist the tendency either to bulge or collapse. For this reason a plate of smaller size may be used than where the curvature of the side walls is constant, that is to say of equal radius.

The tie is narrowest and of greatest depth at its center. Narrowing the center without changing the width of the metal heightens the tie at the center, the point of frequent great strain, and places more metal as nearly as is practicable, in a vertical position to the strain, to strengthen the bond between the rails and consequently prevent the spreading of the rails which sometimes re sults from the bending of ties, and by the relative sharpening of their central portions the ties are more readily embedded in the roadway and therefore less liable to become center bound and bend at points intermediate the rails.

From the center the tie diminishes in helght to a point approximately half-way between the center and ends as shown in Fig. 2, and from the center the upper edges also extend divergingly outward as shown clearly in Fig. 3, this diverging relation of the upper edges of the side walls and the proportionate reduction in height from the center outward of the tie resulting in the widening of the bearing of the tie upon the ballast as well as increasing the width of the points of support for the rails, so that where the weight of the rails and of trains passing over them, is greatest, the tie is strongest, and the ballast-supported surface is large.

From the points numbered 2 to the points numbered 3, the width of the tie is preferably uniform, the points 2 being inward of the rails and the points 3 outward of the same, and the tie gradually diminishes in height and increases in width from points 3 to the extremities of the tie. The strength of these end portions is ample to support the relative proportion of the load which is imposed upon them and their chief function is to provide oppositely-disposed wedges, which when embedded in the ballast, will successfully guard against endwise movement of the tie, it being noted that the central portion or body of the tie will cooperate in this function with the said end portion because atzopposite sides ofthe center erably formed with outturned flanges '4,

which extend from the center-.toithe-extremities of the tie and by preference from points2=-tothe center. andfrom points 3 to the extremities of the tie, said flanges diminishing in width, as-bydhisconstruction' more metal is available for increasing the height :of' the central portion. and? the width of thevend portions. 7 V

, Atiiitscenter-the: tie -is: braced by as cross strap 5'whi'eh bridges the tieian'd terminates in hooks 6,- which fit around and under the flanges iiland thus tend to guard against outward r collapse or bulging of tl1e ava'lls,-and to brace said walls against inward =n1ovement the strap is i formed with depending lugs '7' 'which bear against the inner-sides of I the walls as shown most clearly--i-11 'Fig.-'5.

:To strengthen the tie and therefore guand against the spreading of the r-ails, :it is longitudjinally corrugated at S fronrthecenter to points approximately midway between points 2-and 8: and the end portionsof the tie are transversely corrugated aseait t), to strengthen them against 'collapse under weight: imposed upon them, and the upper edges-of the wal-ls adjacent to the-said end portions are crim-ped at 10 for a purpose which is hereinafter explained.

11 are bridge or tie plates' fitt-ing down upon the :upperedge of-- tl1e wan-of the tie .between

points

2 and 3, and provided with 'downturned =inwvard'ly-'opening hooks l2, engaging the flanges 4, the 'outer portions of=said plates being crimped-at 13' to engage and interlock-with thecrimped; portions 10 of the wa'lls and: thus guard againstv movement 'of the plates'xlengthwise of the tie.

(Dne of the plates 11 is provided at its crimped or outerend with-an upwardly projecting, inwardly 'disposed lug l4, --"stamped out of the body of the; plate, :and stamped out -of the 5 body of the plate outward-of lugli-andat opposite endsof thesame is a pair of lugs 15' which-are bent upwardly and inwardly to cooperate with lug 14 in holding one of the rails-16 firmly upon the-underlying-bridge or tie plate. The companion bridge or'tie plate is provided with a'lugli corresponding to luglet, and'lugs l8 corresponding to lugs l5,"=theonly difl eren-ce residing in i the fact i that the 'lugs' of said companion plate are produced at the inner.

end of' the samesoas to engage the inner flange of the adjacent rail instead-of the outerwflange -asis true of'lu'gs -liand 15, it being *noticed in this connection that 'the construction and arrangement oflthe tie and plates- 114s suchthat the rails are pitched slightly inward to better'withstandtheside thrustsdmposed upon them by 'a moving train. .At points under the rails and beneath the plates 11 are vertically disposed supporting plates..l9, corresponding in contour totheinterior seetional' form of the tie, and to strengthen and stifi'en said support- -i 1g| .-plates,w-th ey are corrugated at 20, or otherwise, and to hold said plates in position the. tie is .formed with upwardly-projecting lugs 21 to receive between them the lower "ends ofplat-es19,--plates 11 being also provided with downwardlypressed projections 22 which fit against --'the'=opposi-te sides'of the plates 19 and -also-aga1nst the inner sides of the -=-walls=of I the tie to assist in holding thesame against inward movement, and outward ofsaldsupporting plates the end portions or extremities of the ties are stiffened by. corrugations 23,=adjuce11t' to and parallel with the upper edges of said portions. iEabh' bridge or tie' plate 1l-is also formed; with-=one on more circular threaded openings '24, and to en'gage eachthreaded opening 2%, I provide" a: bolt fastening -eo11= sistin'g'of screw '25 a? hea'd 26' formed \i ithnfilugflT-to over-licone 0f the flanges of theadjacent rail, the head beingprovided witlvashoulder' '28, it being noticed by :1Gference to Fig. 9, that shoulder 'QS-merges-at one "end into the" threaded stem -s0= that the bolt may be serewed home untilsaid shoulder -bears squarely against the ed 'e of the flange. The" head of the bolt 1 "is also provided with a depending flange "29,101' I abutment'against the extremity of the thread of opening 24 which is above the -surtaceof plate 'll;asshown'in Figs.- 10, ll and 12. To guard against accidental unscrewing movement off-the bolt,-a-short piece of wire 30 is fitted down '-throi 1glr the 'opening'24E between the terminals of the screw thread, the upper end ofthe wire being-bent outwardly and downwardly into groove 3l' inthe upper side-bf theplate and there-held-as the bolt is screwed home, *in whichoperation the flange 29 passes over the upper portion of tl1e wire and clamps thesame' tightly in the said *groove, the threaded portion of the bolt bend-ing tliefiivire against the underside of thetl-n'eaded portion of the 5plate, after which the upper end of the wire isbent upwardly=against the-outersidwof flange 29, and the lower end downwardly against-the lower-end or the thread 24, and then upwardlyso-as to occupy substantially the position -shown in "Fig. '12, Rand "thus guard against unscrewingmovements of the fastening, it 1 being understood that the fasteningsearesecured in'position after the rails are I placed upon. the plates 11 and slipped laterally =under the-lugs stamped out of the same as *hereinbefore' explained.

By reference toFig. 1, it will be-seenthat upon adjacent" ties I the plates are reversed,

thatis -tQsay; upon adjacent ties the plates ll areyso arranged that theirlugs face in ceases reversed directions. By thisarrangement it I will be apparent that the rails .are rigidly secured in position should the bolts 26 be omitted or become inoperative from any cause.

In practice the :ties are preferably filled with ballast, concrete or any other filling and are also embedded in ballast to about the level of the top of the tie. Preferably the bottom of 'the tie is of slightly arched form as shown in Fig. 2, to increase the strength and effect the drainage of water therefrom, it beingunderstood that the supporting plates 19 will not form a watertight joint with the ties and thus prevent proper drainage.

' In Fig. 6, which illustrates a modification of the tieconstruction, it will be seen that 'I provide a short tie underlying each rail,.t-his tie comprising a central portion corresponding to the construction ofthe preferred type of tie between the

numbers

2 and 3 and terminating at each end in a flaringend portion corresponding in construction to the-extremities of the preferred type of tie, and this short tie is provided centrally with a bridge or tie plate 11, equipped with permanent lugs for engagement with the rail upon it and with removable fastening means of the same type as those shown in the preferred construction, for engagement with the opposite base fiangesof the rail.

In practice, it is contemplated for econtunical reasons, to build railway track e1nbodying both the preferred and modified forms of ties a pair of'the short ties being arranged between each pair oft-he preferred type of ties, though it will. be understood that on curves or wherever it is deemed advisable, the short or modified typeof ties may be omitted and the preferred type substituted therefor.

From the abovedescription it will be apparent that I have produced a railway track construction possessing the features of advantage enumerated, vand which, obviously susceptible of changes in the form, proportion, detail construction" and arrange ment of the parts without departing from the spirit and scope of the appended claims.
