t The shelf at the toe end of the frog, namely the end at the leftin Figure l and shown in the sectional view Figure 4c, is provided with an upstanding wall or rib 16, see Figure 4, which terminates at top in a transversely disposed spacer and rall-engaging'portion or head v17 of morew or less {thickness and of length commensurate withthe-spaci'ngintermediate of the converging rail ends 15, 15 in order that the opposite ends ofthe spacer or head portion 17 may abut against the webs of the rails. These opposite ends of the head portion 17 are enlarged vertically and have outer arcuate surfaces at-toprand bottom as shown at 18, .18 in order to more or less conform with the contoun of the rails at the juncture of the web portions with'the rail heads and of the webs with the'base ofthe rails, as
shown in Figure-4c. This transversely disposed head or spacer portion 17 isprovided with a longitudinal opening therethrough adapted to receive a bolt 19 which is also disposed through registering apertures in the webs-of the two rail ends, the bolt'19 consti-' tuting means for also securing the usual fishplates on angle bars 20, 20 whereby the ends of the rails are properly attached to the end a of the frog, the angle bars causing the rail ends to befirmly clamped against the opposite ends of the head or spacerportion 17 as shown in Figure 4. v i The shelf at the toe end of the frog, as shown in Figure 1,is preferably provided 2 with a series of transversely disposed spacer =port-1ons, as shown 1n dotted lines at 17 17 with the distance between the running rails;
. the respective spacer portions are shown cially at the intermediate spreading portions spaced apart lengthwise of thefrog and all apertured 'to receive similar bolts 19 which also extend through the'fishplates or angle Jbars20, 20 and the rails on each side of the frog;
In so far as therail-engaging portions of the frog proper. are'concerned, my frog is of accepted standard construction and configuration, so that specific description ofsuch 5 portions of the frog need not be entered into.
The attaching base-pads or lobes 12,espeofthe frog, arepreferably provided with the verticallydisposed gussets or tapering ribs .21, see'Eigures 1' and 5.
The frog at its intermediatepoint portion indicated; at A and extending lengthwise toward the, heel end of the-frog is formed as shown inFigure 5, where the. base 10, adjacent to opposite sides, is provided with the laterally spaced apart upstanding walls 22, 22, which terminate at the top in the wheel engaging tread portions 23,28. The upper ends of the walls 22, 22 are in turn preferably formed integral with the bridge portion formed-on its upper surface with the longitudinallyextending grooves orchannels 25, 25, arranged on opposite sides of the interme: diate longitudinal rib 26 to provide 'wheel- 7 flange receiving channels.
The outer sides of the verticalwalls 22, 22 are, in turn, preferably reenforced by the tapering ribs 21;,
The heel end of the frog, namely the right hand endvof the frog,,as viewedin' Figure 1,
like the toe end thereof, is also provided with a supporting shelf or pad as shown at 26 for the purpose of properly supporting the adjacent ends of the running rails 15,' 15. V
The general construction of this shelf or pad at the heel end of the frog is more clearly shown in Figure 6, where the base 10 has the attaching flanges or lobes 12 adapted to extend beyond the base of the rails as well as beyond the foot portions of the fish-plates or gle bars 20 whereby the ends of the rails V are properly secured andclamped to the frog.
The supporting shelf 26 at the heel portion has the base 10, at a point'intermediate= of the opposite sides, provided with an upstandingweb or wall 27 having transversely disposed webs 28, 28 on opposite sides formed integral therewith and with the depending rail en aging sides or aprons 29, 29 which in turnare formed integral with the trans- 'versely disposed top'or head portion 30.
As shown in Figure 6, the depending 'por tions or aprons 29, 29 are offset outwardly from the sides of-the'head portion '30 so as to provide the shoulders ,31, which extend beneath the balls or heads of the running rails 15, 15; while the depending portions 29, 29
extend fiush=with the webs of the rails and terminate, preferably, immediately above-- the rail-base.
It is apparent that a firm rail supporting structure is thus provided.
' This rail'spa'cing and supporting portion of the frog tapers gradually inwardly,- nam m. ly toward the opposite end of the frog and is provided with one o'rmore transverse holes therethrough to receive the bolts 19, which' also eXtend through registering apertures in the running rails and angle bars 20.
At a point removed from the extension or supporting shelf of the frogy-the latter is provided" with one or more transversely disposed reenforcing partitions as shown at :32
standing sides and with the'head portion 33 which overlaps the sidewalls as shown. In
the exemplification of the invention as shown in vliigure 1, I disclose the frog at the heel provided with two transverse partitions 32,
in Figure"? formed'integrallwith the up-:
7 which are both apertured' to receive the bolts" 19 whereby the inner ends of "the fish-plates or angle bars 20 are clamped in place against the sides and beneath the head portion 33, as
clearly shown in Figure 7, thereby firmly V holding the ad acent ends of the running rails in'place In gures 8 and 9, 1 illustrate the application of my invention to a cross-over frog.
As the application of my invention is similar at each end of the frog, the showingof one corner or end of the frog is deemed sufficient.
That is tosay, the ends which receive the running rails 15, where thegreatest strains are encountered, are each provided with a rail supporting shelf 33 formed integral with the upstanding rail engaging'element 3 1 disposed along the inner face or side of the rails 15.
The rail engaging portion 34: is formed to engage beneath the head of the running rail and is undercut to receive the flange or base of the rail,' as shown at 35 in Figure 9; while the top of the portion at is grooved at 36 toreceive the flange of the wheel; The portions 34, at each end of the frog, like the rail 15', are aperturedtransversely to receive bolts 37 wh'ereby the angle-bars or fish-plates 38,
i with the rails, are 'i'irmly bolted and clamped in place. The fish-plates 38 are located to the outside of the rails and are therefore bent to lit into the outsideangle of the crossTo-ver frog as shown in Figure 8, thus serving to clamp the ends of two approach rails to the frog. 7
V The rail supporting shelf or'base 33'on iop- V posite sides and the frog at various'tie ena gaging points throughout, is shown provided with the integral base-pads'39, disposed laterally beyond the'sides, the base-pads 39 being apertured at 40 to receive suitable spikes for fastening the frog to the ties.
In Figures 10 and 11 I illustrate the application of my invention to what is known as a self guarded frog,- used more particularly in switch yards the guard being employed especially at the toe end of the frog as shown I sity of employing the-riveted tie are usually employed plateswhich The greatest strains or load encountered are at thepoint where the wheels hit the point of the frog and for that reason my improved frogs are reenforced or tied" together at the bottom intermediate of its ends, thus providl1;

This frog like those previously described, is also provided at suitable tie engaging points with the laterally disposed base-pads 43, apertured to receive suitable fastening means or spikes.
' The frogs at points coincident with the pads are provided with the'supporting shelves formed integralwith the frogs and with the pads, as shown in "dotted lines in Figures 1, 8 and 10, thereby providing a pluralityof tie attaching portions throughout the lengths of the frogs, which therefore obviate the neces-
