GUARD-RAIL.

- Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed December 6, 1912. Serial No. 735,286.

To all whom it may concern:

Be it known that I, EUGENE N. S'rRoM, a citizen of the United States, residing at Chicago, in the county of Cook and State of I Illinois, have invented a new and useful Imsame by a broken View in side elevation;

Fig. 3 is an enlarged section on line 3, Fig. 2, and Fig. 4 is an enlarged section on line 4, Fi 2.

lily improvement enables the guard-rail to be cast, preferably of manganese-steel, in one piece, though I prefer, for the sake of economy, to provide the tie-plates of cheaper metal and, therefore, to fasten the guardrail to them; but this may be done, as hereinafter described, in a-manner to render the plates practically integral with the remainder of the structure.

The guard-rail 5 is a casting, preferably of manganese-steel, formed of a relativelywide intermediate portion 6 with end- portions 7, 7 tapering toward the extremities,

as shown, by inclining their inner faces 8 outwardly and their outer faces 9 correspondingly from the points9 The ends are deflected downwardly to form legs 10, 10 terminating in expanded feet 11 with perforated toes, through which to rivet the feet to tie-plates 12 of relatively-cheap metal. Formed on. the inner faces of the end-portions 7, to extend inwardly therefroi'n, are foot-guards 13 terminating at their outer wider ends in webs 14 extending from the inner faces of the legs 10 and expanded at their inner ends into rail-bracing heads 15. At intervals along the intermediate portion (3 are formed thereon, to extend inclinedly from it, in the outward direction, legs 16 terminating in tel-t 17, like the feet ll, through which to rivet them to tie-plates 12, each leg 10 forming a part of a rail brace including the log, a web 18 extending inwardly from it, recessed in its under side, as shown at 19, and expanded at its upper and lower ends into heads 20 and 21. It is practicable, of course, but not so desirable, for the reason stated, to cast the tie-plates as integral parts of the structure, instead of riveting them to the feet 1 0 and 17, as shown.

In use, my improved guard-rail is applied to a main rail 22 to bring its top-portion on a level with or even above the top of the main-rail head, with the tie-plates on the ties 23 and spiked down thereon through openings in the plates at both sides of the main-rail. In the operative position of the guard-rail, the legs 10 form its end-supports, the heads 15 bear against the 'adjacent underside of the main-rail. head as braces therefor and form with the legs combined end-supports and rail-braces with the foot-guards as integral parts thereof. The 1e s16 form intermediate spaced supports for the guard-rail, and the heads 20 and 21 bear, as rail-braces, respectively, against the adjacent underside of the mainrail head and the adjacent upper side of the main-rail flange, the heads being connected by webs with the 1egsl6 and forming therewith combined supports for the guard-rail and braces for the main-rail.

The guard-rail structure, which is in itself comparatively light in weight and very strong, rigidly reinforces the main; railagainst vertical and laterally-outward movementsfi Moreover, its skeleton-like structure renders it open underneath, thus preventing the lodgment of snow and the accumulationof ice between it and the main rail.

What I claim as new and desire to secure by Letters Patent is- 1. A one-piece guard-rail formed with end-legs and intermediate combined legs and main-rail braces for supporting the guard-rail in position relative to a-main rail. Y

2. A one-piece skeleton-like guard-rail formed with combined endlegs-,antlmainrail braces and at intervals with intermediate combined legs and main-rail braces. 3. A; onc-piece cast skeleton-like guardrail comprising an intermediate portion and mtwardly-tapering end-portions with footguards on said end-portions, combined endlegs and main-rail braces with reinforcing webs at theouter ends of the foot-guards and braces, and combined web-connected legs and main-rail braces extending at intervals from said intermediate portion.

4. A guard-rail of substantially the thickness oftlie head of the main-rail with 5 which it 006 erates zind having legs depending from it at intervals provided with transversely extending Webs and forming a large Open space beneath the body of the.
