To allwwm tf/nay concern:

j 'Be it known that I, RALPH lvWiiLLs, a citizen of the United States, residing at Dayton, inthe county of .l.\/Iontgomery*and` State of Ohio, haveinvented certain new anduseful Improvementsin Railway Ties, of which the following is a specification.

This invention relates to railway ties and vmore particularly lto a tie for open Ytrack work,v erl cross country trackage.

been found too heavy and unwieldy for -general use in railway track construction and repair work. It has also been a. common practice to embed a skeleton tie construction infv a concrete road bed. Such construction, how-ever, is quite expensive and cannot at the present time be practically employed outside of the city. Theobject of the present invention is to afford a metallic tie suitable for installation in open track construek tion, which willvbe comparatively `light and easily transported, capable of being readily installed in either new or old trackage, and which will have sutlicient anchorage to insure it against creepage., Y

Metallic ties are not newy in the art,\but numerous attempts vhave been kmade to employvvarious metallic forms varying from simple ltie beams to complicated shapes.

These.v however, have been heretofore proven excessively rigid. It has been found in practice that while a solid road bed is spoken of as beine' desirable, such road bed must pos sessv a certain degree of elasticity or re silien'cy,` and that without this resiliency la track laid upon either rigid concrete ties or rigid metallic ties will be disagreeable to ride over, and will induce undue wear of rails and ties, as well as rapid deterioration ofthe rolling stock.

A further important feature ofthe :priesent invention is to incorporate with a metallic tie, resilient rail supporting sleeper block-s whereby the objectionable feature of metallic and concrete ties is effectively overthe above primary and other inci- .transverse l wooden sleeper block about to be inserted dental objects view as will more fully appear inthe specification, the invention conlsists of the feature of construction, the

.parts and combinations thereof, and the mode of .operation or their equivalents as claims.

`hereinafter described andy setfforth in the .Y

Referring 4to the drawings, Fig. 1 is a `perspective view of a portion of railway track embodying the tie forming the subject matter hereof, one of which vhas been shown inseetion. Fig. 2 is a perspective view of the metallic form preparatory to receiving ithe .sleeper block. Fig. 3 is a transverse sectional vview of va tie von line'VS-- of Fig.

the t-ieon line 1 -4c of Fig. l. Fig. 5 is a sectional view showing the into the pocket of the -tie and Fig. 6 is a similar view showing the` sleeper block firmly embedded in the tie. v

Like` parts are indicated by similar characters vof reference throughout the several views. y y n l i T he railway tie forming the subject matter hereof embodies a metallic form or shape l', which may be rolled, pressed or otherwise formed 1from 'sheet steel, or other metal.

yThis form l.v is ofelongated rectangular shape, having downturned .marginal flanges 2, while locatedy in the top yface of the form .aredepressed spaced pockets or recesses 3.

Tolighten the weight of the tie and furthermore. totprevent center binding, or teeterijng while in use, an opening fr isr 4provi-ded in the `medialportion of the form 1, and to further reduce the weight other openings 5 are formed adjacent to the ends thereof. These .openings l and 5 may also lieprovided with down vturned flanges 6 and 7 as shown in the drawings, or suchv down turned flanges may be Aentirely omitted. However, these flanges 6 and'v as well asthe clown-turned mar- *ginal` flangesl 2- by embedding themselves in Yl. Fig. 4 isa transverse sectional view of the road way serve as anchorage flanges lto .prevent the creep orfdisplacement of the ties vunder the kimpact,` of traliic. By removing the excess of material from'the center ofthe tie as at Llthe bearing surface 'and resistance of. the. tie at this point are materially reduced in comparison with that beneath the rails, whereby under the impact of traiiic' the .tie will seat uniformlyy upon the road bed, and vwill not rest wholly at its ceri-ter with ,theends relieved or loose, which conditin is termed center binding.

tie, this portion will tendto settle'into the roadbed uniformly with the ends of thetie, the diiferei'ice in pressure to which `'it is subjected being vcompensated bythe reduction of bearing surface. Located in the depression or pockets 3 of the form 1 are sleeper blocks 8, preferably thoughpnot necessarily of wood, which sleeperpblocks restY upon cushion strata 9 of asphaltum or other resilient material placed in the bottom of the depression or pocket 3 beneath such blocks. The use of wooden sleeper blocks submerged ina body ofasphaltum, pitch or other similar material is not new in the artl per se.

Howeveij it has heretofore been the practice to provide a recess in. the tie considerably larger than thefslee'per 'block and entirely `surround the sleeper block with the'yieldin'g "or resilient paclringmaterial. I In practice ithas been found that such ,packing material when softened by summer'heat is readily ldisplaced and'forcedy out'of the recess or pocket by. the pressure and constant poundingof tratlicsupon the sleeperbloclr. Such y,packing material cannot be retained inv` av L 4 structure which contemplates the submer- VIVpreferably sealed with a. suitable material sionv or inclosingjof the sleeper block'therein; IThis ditiiciilty has been overcome by fitting the sleeper` block 8 to the'pocket'or .recess 3 allowing only sufficient clearance between the block and the walls ofthe recess Vto compensate for expansion and'con' ytraction of the parts.

intervening space if any between the sleeper block and the side walls. of the pocket is not subiect vto expansion ory contraction or rendered viluid'fbyk summer heat', nor Yeasily `dislodged by the vibration incident to tratfic overwthe rails,l An `asbestos packing will be Vfound suitablaV lalthough other material bel utilized for caullring or sealing these blocks in theirv recesses 'or pockets @The rails ll, rest upon the sleepe-rbloclrs 8,'and

are ksecured in position' by clamp plates '12,

-which engage the base flange of the railland are' secured .by bolts '1,3 .which entend i through suitable holes 14 in the bottom of ,thepockets'or recesses 3, and thence through vthe sleeper bloc/L18 and interposed stratum of' cushioning material, These bolts carry the clamp'plates 12, which engage; the :base l y The tie as thus-"con-k Y structedy 'is installed on the road bedV and flanges of thev rails.

They further afford an increased degree of safety since there, is much less danger of rails becoming` loosened or spreading, inasmuch as the attachment means affords positive connection of the railswith the metallic form and ,hence .one

rom the above description .it will be apparent thatthere is thus provided a device of the character described, possessing the.

particular' features of advantage before enumerated as desirable, but which obvic ously is susceptible of modification in its form, proportions, detail construction'l and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

lVhile in lorder to comply with the statute the invention has been described in language more or lessspecific as to structural features,'.it is to be understood that the invention is not limited to the kspecific detailsy shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into effect and the invention is therefore claimed in any of its forms or .modifications within the legitimate and valid scope of the appended claims.
