y RAIL-TlE. j 'i To all whom it may cori/'cern` f 'l Be it known that I, 'FRANK NQ MIHILLs, a

citizen of the United States, residing at Arlin tdn Heights,-Boston, inthe county of Su olk and Stateof Massachusetts, have yinvented new and useful Improvements in Rail-Ties, of which the following is a specification.

.This invention relates to railway-ties, and

has for its objects to produce a comparatively simple inexpensive device of this character which will be exceedingly strong and duraable, one tov which the rails may be readily and firmly attached, onewherein spreading of the rails, owing to. one or more of the ties becomingv fractured, is obviated, and one which in practice will be p'racticallyindei 4structible through thefactionof climatic or elementalv changes.

Further objectsof the invention are to provide simple and efficient means for securing the rails tothe ties, one wherein the rails will be maintained firmly and securely in place, and one vwhereln the ties will, to a mea-surable extent, be relieved ofthe vibrations to which the rails are in practice subjected.

With these and other objects-in view the.

f invention Vcomprises fthe novel features of 3o fully hereinafter described.

. n will te understood that warming uw' tieA the b'indin member orcore is placed in a suitable mol prior to filling the latter with plastic material, which is thereafter allowed f to harden, and that the core' thus strengthens the tie, which latter, through the medium of the brace's, receives the greatest'amount of stren that its-otherwise weakest point, or, in ot 1er words, at thatportion of the tie whichv in practice extends between the rails, whereby liability vof the tie becoming fracofthe bars 3 at a point' adjacent its longitudi-` .fatented March 20, `1906. l Application led February 23, 1905. kSerial No. 247,005. y i l tured is minimized. It will be observed, i

however, that should the tie i`n` practice being to its peculiar form, serve to securely bind 75 i come broken'the binding member 2 will, ow-

together the'p'ortions of the tie and prevent j Securedv tothe tie. l'by means of enga ing members or clips 8, in turn retained in p ace by fastening members or bolts 9, is-a pair of i rails 10 of usual construction and arranged in -1 lthe customary's aced arallel relation,-there bein arranged! eneat each of the rails and to w olly -cover lthe -adj acentnportionof the ti'ea steel 0r ,othenmetal wear-plate 11, between which and'the tie there'is in turn'situf ated a cushioning member or plate 12, of 'l 9. `sive in area withthe platen 1 1 and serves in practice to relieve the tie of vibrations inci Ident .to the rails, these plates bein secured wood for fibrousmaterial, ywhich is coexten infplace by means of the bolts 9, w 'chpass throu h suitable openings 12( in the plates. f'

x Em ed'ded in.. the tie 1 -at appropriate points are metal boxes 1'3, constituting sock-I ets to receive thebolts 9', and each havingvat its lower end semicircular enlargements 14 and r15. of unequal'heights and presentingv` shoulders or'abutments 16 l17, disposed at relatively different' vertical elevations, these shoulders bein-g designed for engagement by an angular engaging portion 18 ormed lat the lower end of each of the bolts 9, While upon the 'upper Yendsl of the latter and in.

threadedengagement therewith are nuts 19,

designed for engagement, as usual, with the engagement with the base-flanges of the rails,

clampingplates -to hold the latter in secure,` I IO izo i understood in this connection that .aside of the shoulders in the socket by means of keys or wedges 20, which are entered vertica ly into the sockets incontact with the respective bolts It is to be noted in this connection thatthe openings 12 are of a size toA recelve not only the bolts 9, but also the up er ends of the wedges 20, which are of suita le 'length to project into the openings.

In practice the bolts 9 are entered into the bolts 9, of suiiicient cross-sectional area to wholly ll the body portions of the sockets 13. The bolts having been placed in position, plates 11 and 12 are next positioned andthe 'rails 1 0 seated thereon, after which the plates 8 are seated upon the bolts and secured by means of the nuts 19. In the event of it becoming necessary or desirable to lace a greater number of plates 11 or 12 eneath either of the rails for leveling the latter relatively the lower portions 18 of the bolts are engaged With the shoulders 17, the bolts being thereafter `securedb means ofthe keys 20 in the manner hereto ore explained, this arrangement 'of the parts being possible owing tothe fact that the openin" s 12 are of a size to receive the bolts 9 and a so the ends of the wedges 20, whereby the bolts 9 may be moved to the inner endsof the openings 12 and the wedges introduced at the outer ends of the latter `for holdin the bolts in place.

In Fig. 9 is illustrated a slight modification of the device, in which the tie employed at the joint between a pair of rails is formed with eXtra wide ends, the meeting ends of the rails being secured to said tie by means of the clips 8, held in place by bolts 9, which in turn are entered intov metal boxes in the tie and held by means of fastening keys or wed es in the manner heretofore explained, it eing from forming 'the tie with extra wide ends to accommodate'the meeting ends of the rails the construction and operation of the parts are identical with those above described.

. 5o From the foregoing it is apparent that I.

produce a simple inexpensive tie which in 4what is c aimed as new is- 1. An artificial-stone tie having a binding member embedded therein, said binding member comprising a longitudinal bar and end engaging portions, and a brace attached to the bar and comprising opposite u per and lower trusses and spacing members Ibetween the trusses and bar.

2. An/artiiicial-stone tie having va binding member embedded therein and comprising a pair of spaced arallel bars and end portions connecting said bars, a brace upon each of the bars adjacent the longitudinal center of the tie, said brace comprising upper and lower trusses attached to the bar, and spacing-blocks between the trusses and bar.

v3. A tie provided with a socket having a pair of shoulders disposed at comparatively dierent elevations, a rail seated upon the tie, a plate arranged beneath the rail and fastening means for the rail' and plateincluding a bolt having. an angular ortion ada ted for engaging with eit er ofP said shoul ers, and a wedge entered into the socket in contact with the bolt for maintaining said angu- `lar portion and shoulder in engagement.

In testimony whereof I affix my signature 1n presence of two witnesses.
