T0 all whom it may concern; Be it known that I, PATRICK J 'LYoNs, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of fennsylvania, have invented a new and useful Improvement in Railway-Crossing' Frogs, ofwhich' the following is a full,

clear,and exact description,.referenoe being had to the accompanying drawings, which form a part of this specification. 1

My invention relates to a railway track construction for usein crossing and frogs, on either steam or street railway lines, of such a character asto permit of the ready removal [and replacement of the parts receiving the greatest wear without interfering with or damaging other parts.

In a crossing, for example, the point where the wheel fiangeways meet is subject to greater wear than any other part of the track, due to the jumping of the wheel over the intersecting fiangeway. It is customary to place a removable plate or center in the track at this point, in order to permit of renewal of. the worn portion without the necessity of renewing the entire crossing. The devices for this purpose are found to have man defects. Thus, they are difficult to remove and their removal frequently results in irreparable damage to the entire crossing. Again, ,a crossing, frog, or the like is subjected, whenever a wheel strikes the intersecting point. not only to one blow or shock, but to one and frequently two immediately following secondary blows or shocks, the effect of which frequently is to break the rail ad acent to the center. 7

The object of my invention is to much prolong the life of the crossing, frog or the like. Another object of the invention is to provide an insert or center which will be heldrigidly in position, but which, if worn, may be readily removed and replaced, thus imparting to the crossing a lengthof life equal to that of the rails themselves.

The invention comprises a crossing, frog,

or other track construction comprising a pocketed support for a center, a removable center, preferably of manganese or other especially hard or hardened steel, engaging the pocketed support, and rail sections, separated from or integral with the support, partly embraced by said support and abutting against both the support and the cen ter, the construction being such that the center can be held in and on the support ing one rail end in section.

A preferred embodiment of the invention s shown? in the drawings, wherein Figure l is a plan view of the invention as applied to a crossing only one'of the four lntersections being shown. 7 Fig. 2 is a side elevation of the same, show- 7 Fig. 3 is a section on the line 33, of IFig. .2.

Fig. 7 is a perspective view of the center slightly modified.

Fig. 8 is a perspective view of an entire A intersection with two of the rail sections omitted and one of the arms of the center support shortened.

. The crossing intersection shown in all the figures comprises rail sections a, a, etc., a center plate and a center plate support.

The support is. composed of diverging pocketed members, each comprising a base 6 and sides 0,6Z. As shown in Fig. 8, the sides 0 and d may be made separate, sides 0 being integral withthebase 6, while sides cl are fish plates riveted to the base by means of rivets e entering rivet holes 6. The bottom of the pocket formed b the base 6 and sides 0, d is above the level of the base of the corresponding rail sections.

Sides c, (Z ma be madeintegral, the whole center plate support 5, 0, (1, being cast to shape in onepiece, as shown in Fig. 5, or it may be cast roughlv to shape and then machine groo'vedto form the pocket and drilled to formthe rivet holes; or the center plate support and abutting rails may be cast in one piece, the pockets'being cast with the structure or subsequently 'machine T he removable center plate, which is preferably of manganese steel, comprises diverging arms each composed of a head f. and a web 9. The web 9 is of less height than the webs of the rail sections a (say of about half thereto by means of rivets the poured-in zinc, Babbitt metal or the like will itself firmly holdthe center plate in the height) but is a suiiicient heightto an the pocket of the corresponding supporting member. The heads of the center plate rest I upon the upper edges of thesides 0,-(Z, ofthe supporting members.

It will thus a and the center plate support la -0,11, are permanently secured together, leavinga central pocketed portion to receive and support the center plate f 'g,the heads andvv'ebs of which abut against the heads and the upper halves of the webs of the rail sections;

There being no effective force tending to .dislodge the ccntei' plate, from itscsupporty or. out of alinement with the rail sectional prefer to'boltthe center plate in place by means of bolts i passedthrough bolt holes '4" near the ends ofthe' webs of the center plate. v

After the center plate is positioned and the bolts entered through the sides of the support and the webs of the'center plate, molten metal, either zinc or lead, maybe poured in to fill any. irregular spaces that may exist in the pocket or recess of the center plate; support, thereby insuring the rigidity and solidity of the structure. The center may be easily and quickly removed by releasing the bolts and using two pinch bars to pry up the center plate. .The bolts may not be necessary, as .it is probable that position, as the metal will flow intothe bolt holes and adhere to the sides of the casting. :The center plate formed and inserted as described is adapted to sustain such shocks, whether two or three in number, as are sustained by the crossing when awheel passes the intersecting grooves and save the abutting rail sections from theefl'ects of the secfondary shock or'shocksand thusimpart to the crossing a life equal tothat of the rails themselvesg v In Figs. 7 and 8,the webs-oif the' center plate are reinforced at mythe' sides of the pocketat the point of intersection being shaped 'toreceive the reinforced portion m- I 7 Having now :tullydescribed my invention, what Iclaim and desire to protect by "Letters Patent ise 1.
