RAILROAD-CROSSING.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed February 3, 1906. Serial No. 299,275.

To (l/N/ whom, it may concern:

Be it known that I, CHARLES A. ALDEN, a citizen of the United States, residing at Steelinner edge of the main or stock rails entirely across the lull width of the heads of said rails and is inserted into the recess in the bearington, in the county of Dauphin and State of E rail, the ends of the stock or main rail abut- Pennsylvania, have invented certain new useful Improvements in Railroad-Crossings, of which the following is a full, clear, and exact description, reference being accompanying drawings, of which- Figure 1 is a plan view of a crossing in which one form of my invention is embodied. Fig. 2 is a section on line a; 90, Fig. 1. Fig. 3 is a section on line y y, Fig. 1. Fig. 4 is a V of a crossing embodying a modified form of the invention. Fig. 5 is a section on line 2 2, Fig. 4.

The object of this invention is to provide an improved crossing for railroads or rai ways in which the crossingpoints shall be of hard metal and which will withstand the wear and tear of heavy travel to which this class of crossings is subjected and also to provide a hard-metal bearing for the false flanges of guttered wheels in passing over the crossing-grooves.

The precise character of the invention will hereinafter appear.

In the drawings, Figs. 1, 2, and 3 show a form of crossing in which a steam-railroad track is crossed by a street-railway track or girder tramrail. In said figures, 1 designates the railway-rails; 2, the main track or stock rails of the railroad; 3, the guardrail, and A the bearing-rail. The ends of the railway-rails 1 abut, respectively, against the outer sides of the bearing-rail 4 and the guard-rail 3, as seen in Fig. 1. It will be seen also that the guard-rail and also the bearing-rail are bent outwardly at 3 and 4, Fig. 1, and are recessed vertically to permit the insertion and retention of the sides, re spectively, of a hard-metal piece 5, which hard-metal piece is provided with crossinggrooves 6 6, the upper surface of saidwearplate at the meeting of said grooves constituting the crossing-points, where the great est amount of wear occurs when a wheel is passing over the crossing. The wear-plate is composed of the portion 7, inserted in the recessed inner side of the guardrail, webs 8, nd flooring portion 9 for the grooves 6 and 6, also the portion 10, whose upper or bear g surface is of a width extending and ting against the ends of the portion 10 of said These parts are all firmly hardmetal piece.

means of bolts 11 passsecured together by had to the mg through the respective rails and through the web portions 8 of the hard-metal piece.

The form of the invention shown in Figs. 4 and 5 does not materially differ from that of Figs. 1, 2, and 3, except that the part of the portion 10 of the hard-metal piece 5 of the width of and in line with the head of the main or stock rail is extended inwardly at 10, as also the floor portion 9 of groove 6 and web portions 8, and abuts against corresponding extension of the adjacent crossingpiece, said extensions thus constituting the main rail between the crossing-points. In practice of course the joints between said extensions 10 (marked 11) and between the ends of the guard-rail portions, (marked 12,) as also between the bearing-rail portions, (marked 13,) are staggeredor broken with relation to each other for the obvious purpose of strengthening the crossing at such points. The advantage of this construction is that it gives a complete hard-metal bearing for wheels when passing over the crossing on either track, and the particular advantage of having the part 10 of the wear-plate of a width to extend entirely across the main or stock rail and into the recess in the bearingrail is that it provides a hard-metal bearing at the crossing for false flanges of guttered wheels passing along the main rails.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a crossing, the combination of the main rails, the guard-rails, the bent-out bearingrails, the hard-1netal wear-plates having a portion extending across the full width of the heads of the main rails and into the bentout portion of the bearing-rails, the crossingrails abutting against said guard-rails, and bearing rails, respectively, together with means for securing said several parts together, substantially as set forth.

2. In a crossing, the combination of the main rails, the guard-rails bent out and recessed, the hard-metal Wear-plates having a securing said several parts together, substanportion extending into the recess of the tially as set forth. IO guard-rails, and having also a portion eX- In testimony whereof I have hereunto aftending across the full Width of the heads of fixed my signature.
