RAILWAY-TRACK CONSTRUCTION.

Patented Dec. 25, 1906.

Application filed March 2, 1906. Serial No. 303.853.

(46/, whom it may concern.-

Be it known that we, l'lENI-IY B. Nicnots and GEORGE B. TAvLon, citizens of the United States, residing at Philadebhia, in the county of Philadelphia and tate of Pennsylvania, have invented a certain new and usefullmprovement in Railway-Track Construction, of which the following. is as ecnication, reference belng had therein to.

t e accompanying drawings.

Our invention relates to railway road-beds, and has for its object the improvement thereof in the manner and particulars hereinafter set forth. v It has heretofore been proposed, especially in systems designed by the present applicants, to employ a monolithic rail-sup-- port with holding means for the rails, such that the weight of the latter and of the roll ing load thereon will be taken directly by. the

monolith without the interposition of metalor other separated supports of fastening de'.

vices. Specifically stated, sirch construction involves the use oi concrete laid in asolid and I and shape, which are extended lon itudinally unbroken mass throu bout the length of the rails with yokes or s i es or anchors of some sort embedded in t 1e concrete and holding the rails down thereon. In certain places and under certain conditions it has been. found des1rable,'not to say necessary, to add certain special-featuresdn order. to gain all the-advantages due to the monolithicsupport. Thus in subway or tunnel or other construction where there is no street .tra'l'lic or general crossing traffic to be provided for some form of T-rail is usually employed, and it is found desirable to have this rail sup ported-on ties of some sort.

then to be met is thiszflhe weight of the rail must be communicated direct to the concrete, the ties must be supported so as to per-- mit free ventilation and drainage,-and the securing means must all be readily detachable and of sucha nature as to permit of reol'- the rails and embedded as wel as filled with the concrete, the upperedgeofieach The problem l girder throu hbut its length uprising above the mam bo y ofthe concrete, so as to leave bolts onother. securing means. Instead of using cross-ties we employ a series of short separated ties for each rail, bolted at opposite ends to the two flanges of the box-girder and carrgtying the rail upon their upper surfaces. hese ti'es do not rest upon the girder in any case, but are supported upon the body of concrete therein, whose upper surface protrudes above the level of the flange-faces by a small fraction of an inch. The rails are held down to these ties 'by means of lag-screws passingtlirough leverclamps of 'fi'erent lengths, the clamps on one side of the rail being shorter than those on the other by about one-fourth of an inch from centers, so that asthe rail wears it may bercadjusted to gage 'by merely changing the clamps. r

lnorder to avoid weakenin the ties and girder, the-via -screws are set in staggered relation ande securing-bolts in reversed staggered relation, so that diagonals drawn through the screws and bolts will intersect.

The side channels on our box-girders are made solid, but they are cross-connected by as different distance-pieces and maintain the shape of the girderunder stress, while at the same time permittin the body of the concrete within andwit out each girder to be substantially continuous.

Referring to the accompanying drawings, illustratingou'r invention, Figure 1 shows a volving our invention. mentary detail view ofthe box-girder, tlie rail-support, and the false gages. Fig. 2 shows one girder or rail-support, one tie, and a rail thereon removed from the concrete,

Referring to Fig. 1, the numeral 1 design nates a foundation, such as the bed of;'the roadway in a channel or on a concrete bridge is of no moment. earth, or broken stonc,'or what not. A

trench 2 is formed in this foundation having bottom 4. Along the opposite sides the trench are laid the girders 5 and U, supporting ties 7- and 8, and upon them the rails-9 and a system of skeleton braces or ribs, which actor viaduct. The material of this foundation it may indeed be simple.

the flanges clear for the manipulation of to secure a firm holding for 0th rail and cross-sectionthrough a railway road-bed in Fig. 1 is a fraga lateral extension 3 on each side and a love discont inuous character of the cross-webs is filled in and about them until theyare solidly suitable 11g or a boringmiaclnnc with double materials had to be specially rollcdJ The vertical arrangement 0 .of each girder-the concreteis sloped away the rails we first excavate the trench, if the finished.

also squared, so they cannot turn.

10. The""tr'ench is filled with a body 11 oi composition. such as concrete. in which the girders are embedded to within a short distance of their upper flanges. Onthe outside somewhat and channeled out, as shown at 12, to form a gutter. Between the two gird crs another depression orgutter'lffi is forn'ic'kll, both of these being for purposes of drainage.

L'Ihside eachgirder is a body of the'coinposition, (marked 14,) which on account of the substantially continuous with the main bodyll. W I

V Inconstructing this road-bed and laying same has to be done; The girders are then placed into position, being laidupon a preliminary layer of concrete or temporarily blc cked up, if desired; .Concrete is" then The nature and relation of the mechanical parts we employ appear best in Fig. 2, which is a perspective view; The box-girder 5 is shown formed of the standard channel shapes l5 and-16, having top and bottom flanges 17 and 18, respectively; The top tlai-ige 17 is perforated at intervals, as shown at 19, to receive the bolts 20 of the ties 7. The holes through which each tie receives these bolt-s are both bored at the same time. by using a spindles, and this operation is done quiteaecurately, as W'ellas the punching or drilling of the holes 19. Each bolt 20 receives a nut 21 below the top flange 17, and these nuts conform to theshapc of the flange, being The side channels of the girder 5 are connected by thecro'ss members 22 and 23, the. former being turned vertically and the latter horizontally as regards their llat sides. These are provided with'cnd knees and are riveted to the channel-irons. By the use of standard sizes and shapes in these. irons we are enabledtoproduce? our structure at reduced cost andin better sh'apedhan it the v the mcnibcrs 22 as sists i'n.prevcnting anyfflongitudinal motion by offering broadiacesto the concrete.

The rail 9 is laid upon the ties and secured I by means of clips 24 and 25. Each of these is shaped with a wide heel 26, a reduced toe the gage when the gage-line has worn'au ay.

It can be brought back by merely exchanging clips, placing those on one side or the other, and vice Ycrsa, whereby the )osition of the rail will be slightly shifted. l desired, this operation can be repeated by' reversing the rail itself.

Our construction thus described is particularly suitable for use on straight lines, al-

through we have employed it upon curves. The principal difiiculty experienced therein, however, is that of' properly adjusting the ties so as to keep them radially disposed.

In our claims we shall design'iate the boxgirders as sleepers, since they perform some of the functions of sleepers. It is to be understood, however, that this is a term of definition and not oi limitation.

Having thus-described our invention, what we claim, and desire to secure by Letters Patent, is-
