To all whom it mag concern:-

"Be it known that I, HARRY-"Hess, a c1t1- j Zen of the United States, residing at Glen gariyyinthe countyofFer'gus and State of Montana, have invented certain new and useful Improvements 1n Radroad-Tms, of

- which the following is a specification, ref 1 ercnce being had to the accompanyingdrawlily invention relates to railway ties, and particularly to composite ties. The primary object "of my invention is the provislon ctatie' including" a tie body within which isdisp'osed one or" more wooden cores, the tie being adapted to have the railssupported thereon spikedto' the wooden" cfores or fillin'g members thereby avoiding the difiiculty usually'found in metallic ties of attaching rails to the metallic "ties and also avoiding therigidity of the ordinary metallic tie.

A further objectofmy invention is the provision of-atie of the character described 'whichis so formed that'woodenfilling pieces may bedri'ven in and wedg'edin 'place in the opposite end ar the tie so as: to" hold firmly in'posit'ion and prevent 'any-outward accidental m'ovement thereof. "I, f i p Still another object of myj mvention is the provision of a the of this""d escr i ption so formed that the wooden filling pieces or cores may-be removed when spike killed to permit the driving of other wooden filling pieces, and further whiclr'willpermit the filling pieces to be driven i ntfromj time to time farther and farther into the tie to permit-the redrivingofspikesfi Other objects will appear in the course-of the following description.

My invention is illustrated in the accom panying drawings, wherein: I

Figure lis atop plan view of a tie, one end of the tie being partly. broken away;

Fig. 2 is a side elevation of the tie shown in 1 Fig. 1, partly in section.

. Referring to these drawings, 2 designates a metallic tie which is practically rectangular in cross section. The top web 3 of this outer shell 2 or body of the tie is cut away as at 4 at two places at a distance apart equal to the age of the track. The bottom and side we s 5 and 5 of the body or shell 2 are thickened as at 6 adjacent its opposite ends, these thickened portions each having a downwardly and outwardly in clined face 7 forming a wedging surface, th1sface 7 converging toward the axial center of the tie.

V Specification of Letters Patent.

Patented June 22. 1915.

Application filed March 31, 1915. Serial No. 18,372.

Forced into the opposite ends of the body 2 are the filling pieces 8. It will be'seen that the thickened portions 6 of the tie extend from one extremity of the tie inwardlyibeyond the corresponding opening i for the i rail, and therefore that these wooden filling pieces or cushions are disposed beneath these openings 4. It will likewise be seen from Fig.1 that preferably the upper web 3' on each side of the corresponding opening 4 is provided with lateraloffset notches 9 adapted'to receive the spikes 10 which hold the rail 11in place.

' In practical use the filling ions 8 are driven into place in the ends. of

the tie and wedged against the upper and side webs by reason of the inclined faces 7 ofthe thickened portions 6. The rail is then disposed upon the tie in the ordinary pieces or cushmanner, and the spikes 10 driven into the,

wood of the filling pieces. If in the course of time it is necessary to re-spike the rail for any reason, and ,the spike openings in the filling pieces have become enlarged or are rusty or damaged by rust, the cores or filling pieces 8 may be driven farther in,-or,

if desired, these filling piecesinay be. withdrawn and new filling pieces disposed within the tie. Inasmuch, however; as these filling pieces 8 are surrounded by the metal of the tie they are protected'to a considerable degree and will last for a relatively long time, and further, it is possible, because of the protection afforded these pieces, to use treated timber. Under ordinary circumstances the use 'of treated timber is not economical as the redriving of spikes tends to spike-kill the tie in a relatively short time. It will further be noted that the rail rests down within the recess t'so that it is held accurately to gage and prevented from lateral movement. It will further be noted that the inner end of each thickened portion 6 terminates abruptly and that as the wood of. which the filling pieces are preferably composed is more or less elastic that ifthe filling piece-be driven in so that its, inner permitting the further inward movement of the filling piece.

By my invention I provide a very simple and cheap form of tie having the godd qualities of a wooden tie combined with the good qualities of a metallic tie. Furthermore, it will be seen that I avoid the use of any other device except spikes for holding the rail in place, and thus do away with the difficulty experienced in the case of metallic ties. Furthermore, I provide for overcoming the difiiculties due to re-spiking and spike-killing. The wooden filling pieces not only act as cores or fillers to which the rail is spiked, but also act as cushioning means for the rail, giving the rail the yieldingly elastic support demanded in railroad practice, and these filling pieces further act to deaden the sound due to the travel of a train over metallic ties.

It will be noted that the filler piece is exposed under the rail so as to allow room for wear. The thickenedportions 6 on the side walls should both be on the same side so that thefiller pieces may be exchanged when necessary asregards the ends of the tie, and the good side of the filling piece'be disposed against the rail. I have found in practice that the shoulders formed at the ends of the thickened portions should he not less than one-half an inch and not more than one inch. It will of course be understood that the cuts 4: on the tie supporting the rails at the joints should be made to correspond with the sized angle bars that are used on the road using the ties.

Having thus described my invention,

what I claim is:

1. A tie comprising a hollow shell, one wall of which is thickened, the inner face of said wall being inclined away from the exterior of the tie and toward the middle thereof. relatively elastic filling pieces disposed within the tie and having wedging engagement with said wall.

2. A tie comprising a hollow metallic shell, one wall of which is thickened adjacent opposite ends, each thickened portion having an inwardly and medially inclined inner surface, the upper web of the shell bein cut away adjacent opposite ends, and relatively elastic filling pieces forced into opposite ends of the shell and held in engagement therewith by wedging contact with the inner surface of the thickened portion.

3. In a tie, a hollow metallic shell including a bottom wall and a top wall, the top wall being transversely cut away adjacent its ends for the reception of rails, the bottom wall having wedging faces confronting the cut-away portion, and wooden filling pieces driven into the ends of the tie and having wedging engagement with said faces, the sidewalls of the opening in the upper web being formed with spike-receiving notches.

4. A railway tie comprising a hollow shell of relatively non-yielding material and open at its opposite ends and cut away upon its upper face to form rail seats, one wall of the shell being formed at opposite ends with thickened portions extending toward the middle of the shell and beyond said rail seats and terminating abruptly, the inner face of each of said walls being inclined away from the exterior of the tie and toward the middle thereof, and wooden filling pieces interposed within the ends of the tie and having wedging engagement with said thickened inclined walls and adapted to extend over the .brupt ends of said thickened portions to thereby cause the filling pieces to be held in. place.

In testimmy whereof I hereunto afiix my signature in the presence of two witnesses.
