EDWINH. STEEDIVIAN, or sr. LOUIS, MISSOURI, ASSIGNOR' 'ro oUnTIs & COMPANY "MISSOURI. f

To all whom it may concern I Be it known that I, EDWIN H. STEEDMAN, a citizen of the UnitedYStates, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in F rogs and Crossingsfof which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cast metal railway frogs and crossings of the type that comprises a body portion provided with integral arms, extensions or ends to which the track rails :are connected. The arms or extensions of structures of the character re ferred to are always of different cross-see tional shape and area than the parts of the body portion to which "they are'connected, and in service frequently break at the point where they merge into said body portion.

The main object of my present invention is to provide a cast metal railway track structure of the type referred to which comprises means for reinforcing and strengthen ing same at the points where the track rail arms or extensions are joined to the body portion of the structure.

Another object is to provide a cast metal crossing or frog which is equipped with risers or inclined surfaces adjacent the extremities of the crossing or frog that will guide the outer flange of a guttered or double-flanged wheel upwardly onto the running surface of the structure, said risers M being formedintegral with the body portion and the track rail arms and constituting reinforcing gussetsthat bridge the junction points of the arms and body portion and thus prevent the arms from breaking oif. Figure 1 of the drawings is a top plan view of a portion of a railway crossing constructed in accordance with my invention. Fig. 2 is a side elevational View of same. Fig. 3 is a perspective view of a portion of the crossing shown in Fig. 1. Figs. 4 and 5 are perspective views illustrating slight modifications of my invention. Fig. 6 is a perspective view illustrating a reinforced arm or extension, namely, an arm that has an integral splice member to which the adjacent track rail is bolted; and Fig. 7 is a perspective view of a railway frog constructed in accordance with my invention.

My invention is applicable to any tvpe of cast metal railway track structure that com- MANUFACTURING GOMPANY, OF 'WE LLSTON, MISSOURI, A CORPORATION race AND CROSSING.

Specification of Letters latent. I Patented Dec, 8, 1914 Application filed July 6, 1914. Serial No. 849,317 I prises a .body portion having rail portions provided at their outer ends with integral arms or extensions to' which the trackiails are adapted to be connected, and while I prefer toreinforce and strengthen the arms by means of risers on the body portion that are integrally connected to the heads of'the. arms, I do not wish it to be understood that my invention is limited to atrack structure in which the track rail arms are reinforced and strengthened by members that act as risers, for my broad idea consists in providinga castmetal crossing or frog with means separate and distinct from the main running.

surface portions, the webs andthe base'qo flanges for reinforcing the structure at the points where the track rail arms merge into the body portion of the structure, it being of course, understood that the track rail' arms are of diiferent cross-sectional "area,

ons of the structure;

than the immediate porti to which they are joined. I The crossing shown in Fig. 1 is provided with a body portion that comprises inter-p secting rail portions A of approximately inverted channel-shape in cross-sectionand lntegralarms or extensions B at the outer ends of said rall portions A to which the track rails (not shown) are adapted to be connected, said arms B being of the same cross-sectional shape as the track rails so that the ends of the rails will abut against the ends of the arms. The arms or extensions B are of different cross-sectional shape than the railportions A of the structure,

and in order to reinforce and strengthen the arms B at the points where they are joined to the body portion A of the crossin I have provided the crossing with risers 1 that are integrally connected to the body portion A and to the heads 2 of the arms B, thus forming reinforcing gussets or strengthening devices that bridge the junction points of the arms and body portion.

The risers 1 can either terminate some distance inwardly from the ends of the arms B, as shown in Figs. 1, 2 and 3, or they can extend the entire length ofthe arm to the end of same, as shown in Fig. 4:.

In the form of my invention shown in Fig. 5 a flange 1 that is formed integral with the body portion A and the head 2 of the arm B and whose top face is flush with the running surface of said arm and'body portion, bridges the junction point between the arm and body portion; and the outer end of said flange is inclineddownwardly so as to'form a riser 1. I a y In the form of my invention shown in Fig. 6 thereinfor'cing and strengthening-device 1 extends clear to the end of the arm 13 and also longitudinally-of a splice member C that projects beyond the end of the arm a reinforcing' devices preferablyconstructed 1-5:

to'act as risers that are integrally connected to the body portion and to theheads ofthe arms B inpractically the same manner as in the crossing previously described. At the heel of thefrog are similar reinforcing devices T which are integrally vconnected to the track rail arms and to the parts or the body portion to which .said arms are joined and which'are 'so designed that they act as risers.

Having thus described myinv ention, what Ijclaimisi 1. A railway track structure; comprising 1 "a cast metal body po'rtionprovided with int'egral branching arms which are'lof less g cross-sect1onal' area than the parts'of said body portion to which they are connected, and risers integrally connected to said body portion and to the heads or upper portions 01? said arms so as to reinforce and strengthen the structure at the junction points of said 'arms and bodyportion.

fChpies of this 'patentinay: be obtained. forfive cents each; by addressing the Commissioner oflatents,

' 3. A railway track structure of the Y character described, comprising a cast metal body portion provided with integral arms of approximately the cross-sectional shape of an abuttingrail and laterally projecting portions on the heads of said arms that] are integrally connected to saidbody portion,

each ofsaid laterally projectin'gportion's having an upwardly inclined surface that acts as a riser.

t. A railway track structure of the character described, comprlsmg ,a castmetal body portion provided with integralv arms of approximately the I cross sectional shape of an abutting ra l, a lateral reinforcing flange extending from alongthe side of the body portion along the side of the arm portion so as to strengthen the section where the" armportion joins "the body portionya'nd a riser portionbeingjfor'med in said lateral i' reinforcing flange.
