RAILROAD-CROSSING.

SPECIFICATION forming part of Letters Patent No. 477,687, dated June 28, 1892.

Application filed December 5, 1890. Serial No. 373,660, (No modeL To all whom it may concern:

Be it known that I, ARTHUR J .LMOXHAM, of J ohnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Railroad-Orossing,which invention is fully set forth and illustrated in the following specification and accompanying drawings.

The object of this invention is to provide a strong, safe, and durable crossing for streetcars over or across steam railroad tracks, which shall at the sametime require no disturbance of the steam-railroad track.

The invention will firs'tbe described in detail, and then particularly set forth in the claims.

In the accompanying drawings, Figure 1 shows a generalplan of the crossing. Fig. 2 is a vertical section through Fig. 1, taken at the line V V. Fig. 3 shows in plan, enlarged, details of the corners marked X and Y in Fig. 1. Fig.4 is an elevation of Fig. 3,1001:- ing in the'direction of the arrow Z. Fig. is a part cross-section and part side elevation taken at the line W WV of Fig. 3. Fig. 6 is a side elevation of a part of the guard-rail used, showing a cut made therein for the purpose hereinafter described. Fig. 7 is a view in plan of the same rail before being bent, as hereinafter described. Fig. 8 is a cross-section through Fig. 7 at the line S S. Figs. 9 to 15 illustrate another method of cutting and bending the rails hereinafter described. Fig. 9 is a view in plan showing such method of cutting one of the crossing-rails where it is to form a corner. Fig. 10 is a view similar to Fig. 9, the head of the rail being omitted, showing the cut made in the flange of the rail. Fig. 11 is aview in plan of said rail as it appears after being bent. Fig. 12 is a slde elevation of Fig. 9. Fig. 13 is a cross-section taken through the portion m of Fig. 11. Fig. 14: is a side elevation of Fig. 11 looking in the direction of the arrow q. Fig. 15 is a view similar toFig. 11, the head of the rail being removed.

,In said figures the several parts are respectively indicated by reference-letters, as follows:

It will be observed that the street-railroad crossing consists of three separate parts, the two similar parts A A, Fig. 1, outside of the through steam-railroad rails D D, and the central part B of rectangular shape between said rails.

Referring now to the portions of the crossing marked A A, each of said port-ions consists of one piece of girder guard-rails a b, the parts a being bent at the desired angle to the part, b, as hereinafter described. The guard portion G of said rail is partially cut away, as shown, to the point U, the reason for such cutting away being that said guard is superelevated audit is desirable that no part of the structure should be above the head of the T-rail or steam-railroad rail D at this point, or there would be danger of snowplows, which are sometimes attached to locomotives and overhang the track on either side, catching in such elevated portion. The part b of said guard-rail, which closely abuts against the T-rail D on the outside, has its head portion E and guard portion Gl (see Figs. 8 and 13) planed or otherwise cut away (see Fig. 5) to a level with its floor portion P, and so presents a level top surface. This rail 1) abuts against the T-rail D, preferably level with or slightly below the head of said T-rail, in order to prevent the tread of the locomotive-wheels, which are wider than and overlap the head of the T-rail, riding on the crossing and breaking the same.

Abutting against the T-railD and guardrails a b are the chocks J, Fig. 2, which so look said rails that the street-railroad crossing must be raised or depressed when the T-rails are raised or depressed, and in this manner thelevel of the crossing is preserved. Said chocks are removable and are attached to the guard-rail by means of bolts or studs 0, passing through the web of the rail and secured by nuts 19.

Referring now to the portion of the crossing marked B, this is composed of two pieces of guard-rail h t h i, properly cut and bent, as hereinafter described, abutting each other at the points 7' r and there joined by means of splice-bars. Each of these pieces of rail hi before being abutted are of a double-L shape, and when abutted they form a rectangle, as shown in Fig. 1. The object of making the portion 13 in two pieces is for convenience of manufacture; but it is evident that, if desired, the whole of it can be formed of one piece of rail properly bent. Said portion B is attached to the T-rails D in the same manner as that just described for the portions A A by means of the checks J J, the only difference being that said checks are made longer, in order that the guard-rails may be so located as to leave a groove between them and the through-rails D to allow for the passage of the flanges of locomotive- Wheels. (See Figs. 2, at, and 5.) The superelevated guards G of the guard-rails h 2' are only cut away level to the heads of said rails, more cutting away than this being unnecessary at this point. (See Fig. 2.) From this description of the portion B it will be seen that the rail or rails composing said portion act not only as crossing-rails, but also as guards for the through-rails.

The method of bending the respective rails to form the parts desired is as follows:

Referring now to Figs. 3 to S, inclusive, the head E of the rail a is cut through in plan, as indicated by the L-shaped dark line, Fig. 7, and a miter cut- H is made in its side and lower flange F, as shown in Figs. 6, 7, and 8, thus leaving the vertical web intact. The rail is then bent at the desired angle, as indicated by the dotted lines, Fig. 7, to form the corners of the crossing. When the rail is so bent, an opening is left on its upper surface, and this opening is filled and the whole corner reinforced by the angle chock or portion K K, (see Figs. 3, 4, and 5,) bolted or riveted to the web of the bent rail.

Another method of bending the rails is shown in Figs. 9 to 15, inclusive. In this method the top of the rail is cut square across and down to the web connection 6 and then horizontally, as shown at L, Figs. 9, 11, and 12, and the lower flange (if one exists) is mitered, as shown at M, Fig. 10. The rail is then bent at the desired angle, as shown in dotted lines in Figs. 9 and 10 and full lines in Figs. 11 and 15. When the rail has been so bent, its head portion overhangs, as shown at L, Fig. 14, and this is reinforced by two plain splice-bars n, riveted or bolted to the web of the rail, as shown in Figs. 13, 14, and 15. In bending the rail its web portion is stretched to permit the corners to pass each other, and the space so created is closed up after the bend is made, so that. the upper surfaces are in contact. This can easily be done by heating before bending.

It is obvious that whichever method of bending the rails is employed the crossing when completed presents the following-named features: first, a continuous and through web at the point of the bend, and, second, a continuous and through surface for the street-ear wheels to take on the outside portions A A.

The dotted lines marked a h in Fig. 1 are intended to show in outline the rails marked a h in full lines before being bent into the required shape.

The letters T T indicate, respectively, the cross-ties of the steam and street railroad tracks, and C plates laid under the rails of the street-car track. It is preferable that the rails composing the street-car track should be of less height than the T-rails of the steamrailroad track, because the latter rails vary in height in different places. By making the former rails of less height the adjustment of the surface level can be effected by inserting the plates 0, of a thickness to suit each case, under the street-car rails. If the latter were made deeper than the T-rails, the ties under the steam-railroad track would have to be cut or leveled down.

The crossing herein described can be put in a T-rail or steam-railroad track without disturbing the latter in any Way, which is a great desideratum.

The rails of the street-railroad track shown in the crossing are what is well known to the trade as girder guard-rails and are preferably provided, as shown in the drawings, with lower flanges, although this is not a necessity. If desired, any other suitable form of rail may be used instead of girder guard-rails.
