UNXTE RALPH J. WELLS, OF DAYTON, OHIO. v

' RAILWAY-TIE.

Be it known that I, RALPH J. WELLS, citizen of the'United States, residing at Dayton, in the county of lMontgomery and State of Ohio, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification. y 1 My invention relates to railway track structures and more particularly to a new and'novel -form of cross tie therefor. e The object ofthe invention ,is to Simplify the structure of such devices whereby they will not onlyV be clieapened in construction, but willbe more eficient in use, of maximum strength, safe in operation, and unlikely'to get out of repair. l y

A-furtherv object of the invention is .to provide a vformof sleeper or support for the railway rail which will afford a degree of resiliency simulating that of the earth bedded Wooden tie formerly used while possessing the permanency of modern' concrete constructions. l

A further object of the invention is to provide a tie construction'which-is easily `capable of transportation and readily adaptable to different conditions of use and which may be readily and quickl-yassembled into the track construction, and in which the perishable parts including the fastenings, the sleeper block and cushion may be conveni iently and quickly replaced.

l is a top plan -view of the construction formA With the above primary and other incidental objects in view, as will more fullyl appear in the specification, the 'invention consists of the features of construction, the parts and 'combinationsthereo and the mode of operation, or their equivalents, as hereinafter described and set forth inthe claims.

.l Like parts are indicated by similar diaracters of reference throughout the several views.

lAmong the many attempts to providean artificial tie possessing the peculiarqualiiications and resiliency -of the,A earth bedded wood tie, numerous attempts. have beenv made to provide ties of concrete ,ouother similar material with an embeddedswooden sleeper block.- In some lnstances such wooden sleeper blocks have been submerged in a vbody of asphaltum, pitcher ,other similar material. None of theseconstructions, howz ever, have proved suiiicientlysuccessful lto warrant general `adoption and none have gone into general use. In applying such asphalt or pitch embedded sleeper blocks to concrete 'ties, it has heretoforel beenythc i been found by experiment that such plastic cushioning material may` be successfully retained by making the sleeper block avclosure for the recess or receptacle and allowing only suiiicient clearance between ltlie;blr ck and the walls of the recess to compensate for the expansion and contractionofthe parts.;V v

This feature has been `embodied in thepres-j ent invention, in .which the rail rests di., rectlyon the sleeper blockwhich` is in turn cushioned uponthe packingm'aterial. Am

' other disadvantage of artificial ties as ordinarily constructed is that of excessive ,weight andthe inconvenience of transporting the ties from theplace of manufacture tothat of use. To overcome this difiiculty the cross tie forming the subject matter hereof is of skeleton form capable of 'being shipped l,in knocked down or disassembled form` to be assembled and embedded at the place of use.

Referring 'to' the drawings, 1 1 are box! like lreceptacles'preferably sheet metal but which may be of fiber. composition, or other suitable material.y Fitted 'within the receptacles 1 are sleeper blocks 2 of such proportion in relation with the receptacle 1 as to form a closure therefor. The sleeper blocks 2 are shaped' t0 fit the receptacles leaving sufficient clearance to compensate for expansion and contraction of the parts. Before inserting the sleeper block y2 within the receptacle 1 a cushion or bed 3 is provided therein of plastic or semi-plastic material such as asphaltum, pitch, tar, rubber, composition, or other suitable yielding material. This material underlies the sleeper block 2 and forms a yielding resilient cushion 3, The clearance space 4 intermediate the block and the sides of the receptacle are likewise filled with packing material.- However, this clear space comprises` a mere crevicetoo. small to permit the escape of thematerial from -beneath the block. Material of the character described and consistency of that employed for, the cushion will not readily site sides of the pointof operation.

pr s through a restricted crevice'such as that afforded by the clearance space. Therefore the sleeper block constitutes a closure for the receptacle 1 which serves to retain the cushioning material therein. The block 2- preferably extends somewhat above/the level of the top of the receptacle 1 and although yfree to move downward against the tension of the cushion 3, it is limited in its upward movement by `studs or bolts- 5. The sides of the sleeper .block '2 are recessed or notched, as at 6, to receive the studs or bolts 5. The sleeper block preferably comprises an integral unit in the original construction. However, the block as well as the cushion 3 and fastening bolts 5 will require occasional replacement. At such time it is an easy matter to cutout the wooden sleeper block 2. The rail may be released from the clamp plates 8 at oppo- The rail. may then be jacked up to give access to the receptacle 1. To avoid the necessity of elevating the rail to an extreme height sufficient to permit the insertion of the block 2 over the studs 5, the renewal block is preferably formed in `sections as shown in Fig. 8. The side sections 2SSL are first insertedrand moved outward with the notchesG engaging the studs and the intermediate section 2b is then inserted. To facilitate the insertionA of the intermediate section 2b this section may be again divided diagonally as at 2c. The respective portions may then be inserted from opposite sides. rails 7v restdirectly upon the'sleeper blocks 2 andare secured in position by clamping plates 8 engaging the base flanges of the 4rails and secured by the nuts 9 upon the studs 5. In'order thatthe fasteninglstuds 5 may be renewed without .destroying the structure, the receptacles .1 are provided with key hole slots 5a invtheir bottomsin which the heads of lthe bol-ts are engaged.

The track A lVhen the block has been removed, as before described, the studs 5 may be easilyshifted laterally'in the key hole slots 5? and then disengaged therefrom, it being understood that suiicient clearance orpocket is provided in theunderlying concrete to permifsuch movement. This may be accomplished by drilling or chipping away the concrete through the key hole slot after the block and cushion have been removed. f

This capability for replacement has been found quiite valuable as it enables the repairs to be made without interfering with the traflic over the road as would be the case if it were necessary .to destroy and replace the concrete body or\\ formation.. In such case traffic would necessarily be 'suspended until the new material might set or harden.

The receptacles 1 with the` inserted cushioned sleeper block are conne ted one to the other by means of transverse a gle bars 10 preferably formed in two sections and joined intermediate the receptacles l, as in 'cated at 11. These angle bars are preferably l cated at vthe'base angles. of .the receptacles and are engaged therewith by the studs `5 which extend through the bottoms of the receptacles 1 and engage in recesses or notches 12 inthe angle bars. The Vangle bars are preferably connected one with the other by means of cross bars 13riveted o r boltedto the angle bars. The angle bar sections thus secured to each receptacle form parallelA arms projecting laterally from the recepta cle and are adapted to be engaged with similar parallel arms projecting'from the oppo-` site receptacle to form the tie. ln placing the device in use parallel trenches may be excavated across the road bed in the positions to be occupied by the ties whereby independent concrete ties will be formed or the road bed may be excavated throughout. In the latter case the excavation is preferably deepened bylongitudinal trenches at each side beneath the positions occupied by the receptacles 1. The cross tie sections are then attached to tlie base flangesof the rails by means of the clamping plates and studs and *the-angle bars are connected one to the other in proper relation. The track rails are leved cross trenches or within the excavated Y 20 great durability, possessing the required del the rails.

may be embodied inindependent ties manufactured at a distance from the point of use.

It is to be understood that the receptacles l and the embedded sleeper blocks may be located at any desired points throughout the length of the angle bar. This-is found especially convenient in the placing of special track work such as crossings, frogs, etc. In Fig; 5 there is shown a supplemental receptacle lwith 'its sleeper block located intermediate the primary sleeper' blocks supporting the track rails. This additional sleeper block is adapted to support a raillG inclined to the track, i. e., a cross-over or sliding rail.

In track constructions for electric railways the construction herein described forms a cross bond or electrical connection between It is found in practice that the const-rue tion as above described affords a structure of gree of resiliency, and which is convenient and economical to install. While the reduction of the extent of the clearance space may seem but a variation and small step, itis however, the difference which has turned failure into success.

From the above description it will be apparent that there is thus provided a device of the character described, possessing the particular features of advantage before enumerated as desirable but which obviously is .susceptible of modification in its form, pro` portion, detail construction orv arrangement of parts Without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to certain structural features, it is to be understood that the in vention is not limited to any specific details but that the means and`mode of operation herein described comprise but oie method of putting the invention into effect and the invention is therefore claimed broadly in any of its possible forms or modifications Within the scope of the appended claims.
