RAILWAY-CROSSING.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application tiled January 24. 1907. Serial No. 353.923.

This invention relates to an improvement in railway crossings, and more particularly to that type 0f crossings employing hard metal frogs at the corners thereof.

rlhe object of the present invention is the provision of a crossing of this character, which is so fastened that the rails will not be subjected to excessive wear from the hannner blows of the wheels in passing thereover.

A further object of the invention is the provision of a crossing of this character-which when assembled will present a strong rigid structure, and the several parts 0f which may be readily removed and replaced when worn, without disineinberng the entire structure.

A further object of the invention is the provision of an improved hard metal frog or center plate for the corners of the crossing.

Other objects of the invention will be apparent from the detailed description hereinafter, when read in connection with the accompanying drawings forming a part hereof, wherein a preferable embodiment of my invention is shown, and wherein like numerals of reference refer to similar parts in the several views.

In the drawings, Figure l is a plan view of my improved railway crossing, Fig. 2 is a cross section on line 2-2 of Fig. l, Fig. 3 is a cross section online 3-3 of Fig. l, and Fig. 4 is a cross section of a modified form of frog or center pla-te for the corners ofthe crossing.

Referring now more particularly to the drawings, A designates the frogs or center pieces, which are secured .at the four corners of the crossings. Each of the frogs or center pieces comprises a flat base plate A which is designed to be'seated in a suitable seat in the upper face of the tie, so that the top thereof will lie flat with the top of the tie, and a portion A2 of approximately parallelogram form extending upwardly from the central portion of said base plate. The side walls of the rectangular portion of the several frogs or center pieces A are provided at their juncture with the base plates A of said frog with inwardly extending recesses a, which are designed'to receive the flanges of the rails, which are positioned adjacent thereto, when the parts of the crossing are assembled and along their upper edges with recessed portions a, which are designed to receive the heads of said rails. The tops of the frogs or center plates are flat and are provided with crossed grooves extending from the corners thereof, which are designed to receive the flanges of the wheels in passing thereover.

B designates rail members, one arm of each of which is in alinement with and forms a part ofthe running rails of one of the tracks of the crossing and the other arm of which is bent at an angle to form a part of the running rails of the other track of the crossing. The rail members B are each formed by bending a straight rail twice intermediate the ends thereof so as to form an.angular portion b at the corner thereof, when the sections of the crossing are assembled. The angular portions b of the rail members B rest upon the bases of the frogs A, and lie along side the outer side walls of the rectangular portions thereof, the flanges and portions of the heads of said angular. portions adjacent the rectangular portions of the f rogs engaging the recessed portions a and a thereof, so that the tops of said rails will lie ush with and form a substantial continuation of the tops of said frogs.

O designates four substantially U-shaped members formed of track metal, which are designed to be secured between the running rails B of the two tracks of the crossing, the arms C of which constitute the guard rails for said running rails, and the bases (l2 of which constitute the inner running rails of the crossing. The arms C of the members C are connected to the bases thereof by angular portions c, which are designed to rest upon the bases of the frogs, and to lie along side the side walls of the rectangular portions when the parts of the crossing are assembled. The inner guard rails of the crossing are formed by four members D, the arms of which extend at a-n angle to each other, and which are connected by angular portions d which are designed to rest upon the bases of the frogs and to lie along side of one of the side walls of the rectangular portions Af of the frogs A. The adjacent ends of the arms of ythe members D are beveled, as at d so that in the event of excessive wear or injury, one of said members may be removed and replaced without disturbing the others. The flanges and portions of the heads of the angular portions c and d of the members C and D adjacent the rectangular portions of the frogs engage the recessed portionsa and a thereof, so that the tops of all of the rail members secured adjacent the frogs lie flush with and form a substantial continuation thereof.

E designates angular brace members which are secured within the corners of the rail members B. The brace members E are preferably in the form of rails, the tops of the heads of which extend flush with the tops of the running rails B, so that the edges of said running rails will not be subjected to excessive wear from the hammering of the wheels in passing over the crossing.

F designates U-shaped brace members, formed of bent rails, which are secured within the U-shaped members C, the arms of said members serving to brace of the tracks of said crossing.

Suitable filling blocks are interposed between the l several ruiming rails of the crossing and their guard rails, in the usual manner, and between the brace members and the rails to which they arc secured. lhe several sections of the crossings are assembled by suitable bolts which pass through the arms of the adjacent rail brace mcmbe s, and it will be noted that owing to the particular construction of the members constituting the crossing, none of the parts thereof are connected by any fastening means to the frogs or center pieces.

The frogs or center pieces A are formed olf cast steel, but where the crossing is located at a point where there is unusually heavy ti'allic, it is sometimes desirable to utilize frogs of cxtmptionally hard material, and for this purpose l have provided the modified lorm of frog illustrated in Fig. 4 of the drawing, ln this form the frog is provided with a top A, which is formed of tool steel, which is united to the steel body of the frog by casting. To perfect the linien of the hardened tops A with the steel bodies of said frogs, said tops may be provided with projections` A, around which the body of the frog is cast. From the above-described construction it will be seen that in as much as all el' the rails adjacent the frogs or center pieces of the casting are supported upon the bases thereof, a crossing is providedwhich is strong and durable and the parts of which will not readily become loose, and that in as much as the tops of all of the rails adjacent the frogsdor center pieces extend flush therewith, and form a substantial continuation thereof, said rails are protected from excessive wear from the hammering of the wheel.

While in the crossing illustrated in the drawing, I have shown tracks thereof extending at right angles to each other, it will be obvious that my invention is equally applicable to crossings in which the tracks cross at other angles, it being simply necesn'y in each instance to provide corner pieces, the rectangular portions of which are of such dimensions that the grooves connecting the Corners thereof will cross at the proper angle, and form the .Several rail members which go lo make up the crossing with the arm extending at the proper angle.
