INSULATED CUSHION STEEL TIE Specication of Letters Patent.

Patented Feb. 2o, 1912.

Application led September 24, 1910. j Serial No. 583,556.

To all who/m t may concern:

Be it known that I, THOMAS E. VatGHN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Insulated Cushion Steel Ties, of which the following is a specification.

This invention relates to metallic or steel ties.

The objects of this -invention are to produce a tie which will be constructed so as to resist the stresses to which it is subjected when on the track, which will possess all the desirable characteristics of a wooden tie as to cushioning and insulation features, and which is constructed so as to be retained in position by the ballast.

Further objects will appear from the detail description taken in connection with the` accompanyingl drawings in which:

Figure l shows a longitudinal part sec` tion, Fig. 2 a plan view, Fig. 3 a sectionalong the line 3-3 of Fig. 1. Fig. l a section along the line 4 4 of Fig. 2, and Fig. 5 a detail of the bearing cushion in side elevation.

The tie consists essentially of side members connected and braced by cross members or brace plates so as to form a braced skeleton structure. The endsof the tie are con` structed to receive cushion blocks preferably of wood for the purpose of supporting the rails on the tie. The brace plates yin addi tion to performing their function as bracing means of the skeleton structure also perform the function of retaining and .securing the cushion blocks in position on the tie.

One of these brace plates is movable so as to the side members by rivetspassingk through the. flanges of the plates and through the webs ofthe side members. -The outside plates however are movably-secured to the side niembers',vandiin the 'specific construction sliown these plates are pivotally secured at their lower ends to the side members by rivets passing through the lower ends of the flanges on the plates and through' the webs of the side members. The upper lends of the plates are arranged to be seicured in position by bolts- B2 passing through holes B in the flanges and webs of the plates and side members respectively. The plates B andB are inclined, one plate of each pair being inclined toward the other to form .together a substantially dove-tailed recess adapted to receivera similarly shaped cushion block C which rests upon a plate, C on the 'flanges A of the side members. This cushion block is arranged to be inserted or removed by removing the bolts B2 and swinging the plate B to dotted position Fig. l. VAfter theplate B is again bolted inplace, the plates B and B will retain the cushion block in position against both longitudinal and transverse movements. They cushion block as positioned in the tie projects slightly above the anges so as to support the rail thereon out of contact With the metal rail body. The rail is preferably' reissuedv Oct. 3l, 1911. This rail support l plate D is secured on the cushion block by mea-ns of the lag screws D', and the ,plate is provided with upwardly extending lips D2 adapted to be turned over the ianges of a rail D3 inserted therebetween as shown in the drawings, and as`fully-described in the ,patent referred to.

It will thus be seen that the invention accomplishes its objects. Atie is produced which will have maigimum strength with minimum Weight of material. The tie Vis a braced skeleton structurefin which the cross or brace plates perform not only the function of bracing and strengtheningr means, but also the function of retaining the Gushion blocks in pos-i-tion.. These retaining means therefore ldo not detract fromgibut rather add tof the strength of the completed tie. The entire `tie as built up is constructed to withstand the bending and twisting stresses to which it is subjected lwhen in .useon the rail bed. The ballastcan work up yinto the hollow tie and above the flanges A as shown in Fig. 3 so as to eflcientl-y hol-dA the tie in position on the road bed. The

cushion blocks transmit the Weight to the tie and form insulating blocks to insulate the rails from the road bed and thus leave the rails unimpaired for signaling purposes.

It is obvious that. various changes may be made in the details ofconstruction Without departing from this invention, and it is therefore to be understood that this invention is not to be limited to the specific construction shown and described.

Having thus described'the invention what is claimed is:

i l. A metallic tie of channel form having vertical webs, brace plates secured to and connecting said Webs to forma braced skeleton structure, said brace plates being located in pairs, one pair at each endoi said tie, to form cushion receiving recesses, and cushion blocks located in said recesses. the brace plates vof a pair being inclined one toward the other, and one brace plate of each pair being movable, to removably retain said cushion blocks against longitudinal and transverse movements with respect to the tie.

2. A metallic tie comprising side members veach consisting of ay vertical web and a 'flange extending laterally and inwardly from said web, brace plates secured to said Webs and connecting said sidemembers to form a braced skeleton struct-ure, said brace plates being located in pairs, one pair at each end of said tie to form cushion receiving recesses, and cushion blocks located in said recesses and resting on said flanges, the brace plates ofa pair being inclined one toward the other anclgengaging the ends oia cushion block to retain the cushion blocksngainst longitudinal and transverse movement with respect to the tie.

A metal. tie comprising side plates having inwardly extending flanges along their bottom edges at right angles to said plates, rail carrying cushions mounted upon said flanges at either end and having angular ends, spacing channels in opposition to said' ends and connecting said plates, some of said channels pivotally mounted with means for holding them in posit-ion.

4. A metal tie comprising side plates, in-

wardly extending flanges along their bottom edges7 rail carrying `cushions mounted upon said flanges at either end and having angular ends, spacing channels in opposition to said angular ends and rigidly carried by the side plates, together with spacing channels at the ends of the tiiin opposition to said cushion and rotatively mounted upon the side plates.

5. A tie comprising a metallic body hav ing spacing members and insulating cushions held in position by said spacing niembers, one of said spacing members pivotally mounted. i
