Toall whomy it may concern erence being .y preclude danger of `citizen of the United States, residin UNITED sTATEs PATENT oEEIoE WILLIAM W. rHECK, 0F STEELTON, PENNSYLVANIA.

' RAILWAY-BAIL.

I, WILLIAM W. HECK, a at Steel-ton, in the county of Dauphin and tate of Pennsylvania, have invented 'certain new and useful Improvements' in Railway-Rails, of which the following is a specification, refhad therein to the accompany- Be it known that in 'drawing y his invention relates broadly to railway rails and more specifically to rails of the sectional type in which a tread-component is removably 'supported in' a base-corn ponent.

The primaryiobject of the invention isto provide arailwa'y rail in which a treadcomponent is supported in a base-component in such manner that low pints are practically precliided whereby an absolutelyl withoutfdisturbng the baseicomponents 1n which nit is' y supported.

Still another object'ot` theinvention Ais to provide a railway'rail i'n which is included a series" 'of abutting base-components that constitute practically a permanent structure and `inwhich are to" be supported'a series oi tread-components so formed and constructed asto be interchangeable and capable of being turned end for end, if desired.

AV still further object of the invention is to provide a railway rail, of the 'character specified, which is readily rolled ijn the mill ntothe'` required shape, economically and readily, and on which it is unnecessa to do anyfmachme work except the punc ing of bolt-holes. further'y obj form the' base-component of a sectional rail,

points of reatest strain.

A still rther object of the invention is to provide a sectional railway rail, includn base and tread-components aggronp relatively as t0 cause the 'base-component, to support the tread-com onent atthree points at `least andv independent of the i securing bolts, whereby shearing ofthe latter is prevented.

The invention seeks in general to provide.

a rail-'structure which is particularly?adaptv ed for use onvrailways where thev traiiic is heavylor the speed of the trains is high, and which structure, from0 an operative stand# point, will in practical use possess a hi -h degree 'oeiliciencyg ri ``dity, and dura and which, .structura ly consideredywill be of reat simplicity. i y ther objects and advantages are also present iny the. invention and these will be more or less obvious from the annexed draw.` ings and the following descri tion.

' he invention resides broad yin the fea tures of constructioln'and in the aggroup- 'ment of the components thereof, all as will ility, i.

be exemplified in .the construction lherein- Y after set forth, and the scope of application of which 4will be indicated inthe c aim hereto-appended. A That the invention may be clearly com prehended, drawings yillustratin some :of the possible embodiments anduti lzatio'ns of the same are heretoappended as a -pa-rt l01E this disclosure; and in vwhich drawings- Figure 1 is a view in perspective, partly in section, of a` railway-rail constructed 1n s accordance with my invention;

Referring to these drawings, the referencen vertical transverse@ acc y tion 'ofthe structure; and y fi" ect of the invention is to w the ruil-somnoaearin' numeral 1 desi nates, generally, a base-portion which, in t is instance, is provided with an elongated groove '2, the walls 3 of which converge downwardly to present a substantially flat bottom 4, vThe walls 3 terminate in outspreading flanges 5, a substantial ortion of the upper surface of each of w ich is curved, as at 6. These curved surfaces, as best seen in Figui, form arcuate continuations or extensions of the diver ing walls and extend to the tips or outer e ges of the flanges into approximate alinement with the sides of a head-,portion on a com' onent about to be described. It is to be 'un erstood that a, series'of these base-portions 1 are tobe arranged in an alined and abutting relation so that the grooves 2 of each two components also aline and are practically continuous.

The reference-character 7 designates, generally, the-.tread-component which, in this instance, is shown as including a head-portion 8 havin its under-surfaces 9 rolled to conform to t e contour of the uppersurface ofthe flanges 5 of the base-component. The head-'portion includes a tread-.surface and lsides 9 spaced apart in approximate parallelism. The under surfaces of the tread- `A each having :a bearin -component are curved, as at 10, and lthese curved surfaces extend in arcuate arrangement from the `sides of lthe head-portion to a point, 11, where they terminate in diverging sides of a substantially V-shaped tongue 12 formedonthe tread-component. The curved portions andV wedge-portion of each component are arranged to it snugly together, in a correspondingly shaped portion of t e other. The lower edge 13 of the tongue is substantially square and adapted to rest on the bottom 4 of the groovefin"thebase-component. s

, Each base-component is, preferably and as shown, provided with eight spaced-apart boltehole's14,`which,.as shown in Figs. 3 and .component lis 5, are preferably elongated, while each treadrovided with an equal number of bolt-holes 15. The number ofholes may, ofcourse, -b'e varied. Bolts 16 are disposed in these bolt-holes 14 and 15 and have their nuts 17, orasubstantial portion thereof, rojecting beyond theplane of the side- '4 sur ace of the tread-com onent, whereby such nuts mayy betighteneonvenientl Itis to be understood that the two a utting ends of eachtread-componentare to occupy aposition intermediate of the` ends of the basecomponent which supports them; from-.which it follows that the abutting ends of the base-componentbreak joints with the treadcomponents.

The elongated'formofythe holes 14 in -the "base-'component permits contraction and ex- '.pansion of the-ralls.

In Fig.' 5, I have disclosed the manner of connecting my improved rail to a frog or slight bending of the metal at t add to fthe resiliency. of the flanges. These grooves, in conjunctlon with the curved bearing surfaces of the components, ermit a lrfat point and this allows for expansion and contraction of the parts without binding between the head and base flanges.

By reason of the aggroupment of the components 'and the manner of clamping them together by the bolts, as already described, the objectlonable feature of low joints is prevented, and this is an important consideration in railroad construction. Moreover, by reason of the feature of removability of the tread-components from their supporting base-components, these tread-components are replaceable, or interchangeable.- Infact, they may be turned end for end, if desired.

It is also to be understood that it is a feature of my invention-notv to undercut or otherwise form any portion ofthe` components in such manner as to weaken them at any point. A l' It is also a' feature of `my invention to mount the tread-component in the basecomponent in such `manner that the former will be supported b the latter at three points at least, name y, bythe flanges engaging the under surfaces 9 of the headportion and by the lower edge 13 of the tongue seating onv the bottom 4 of the groove in the-base-component.-

B -reason of the :fact that the walls 3 of the ase-component are not arranged in parallelism, it is' not so essential that the tongue ponent. Moreover, -this arrangement avoids any tendenc of the bolts 16 to ca `any of this we ig t or strain.; hence the.u

of shearing 'cf-,the bolts Vis rendered m the 'foregoing will be am I have succeeded in evi a ma, structure which is well adapted to achieve' .thel several objects and ends in view. The

structure is simple and'eompact in form, and the componentsnthereof. are readily constructed.
