View of a railway cross-' j )Figure lis aiplaii of yF ig. 1.* Fig'. 3 is .,anenlarged cross-sec of my invention are, first, to produce an eX- ceptionally strong rigid cast metal structure that will readily yre'sivstlwear and vibration to jected; second,v to produce a railway crossingk wherein the crossing rails have hollow triangular body portions surniounted by integral-` balls'andllange guards, and, third, to con-,

rails yin'siich ainanner that the tread surpound in passing over the intersecting flange .To the above purposes iny invention consists in certain features of novelty hereinafter more fully-described and claimed.

Referring by numerals to the accompanying drawings, 1 designates a base plateand formed integral therewith is a pair of upwardly projecting inclinedwebs 2, which, together with the base plate l forni a hollow triangular rail body and the side edges 'ofthe base plate project beyondtlie lower ends'of the webs 2 inorder toi'eceive the spikes'or like f" faening devices utilized in anchoring the cross'- ing to the cross ties or foundation. The base plate'is perforated at'suitable intervals in order to receive the supporting means for thexcores that occupy the space within the formed. The upperendsof the webs 2 are body comprisinga ball 3 and-an upwardly projecting curvedl flange guard 4 the upper 'specification of Lettersratent.

` end of which'guard projects. above tliep'lane occupied by l a.citi`zen of zthe UnitedStates, residing in Th St.v Louis, Missouri,"'2 have..invented 'oe'rtaiir new and useful lmp'royeme'nt's" in 'Railway- Crossingaof which the-'following is a full,

the tread surface of the ball. e space between thelball and the flange guardv forms the liange groove-5. As shown in Fig, l, four` intersecting crossing. rails are formedintegral with one another to forni y and in casting Vor forming the saine thebottoms of the grooves 5 gradually decline toward the points where said grooves intersectjasdesignated byy 5a,

`and likewise the topor-tread surfaces of the balls 3 gradually decline toward the points ofintersectionas designated by. 5P. By Ysuch construction the flanges of the kcar wheels engage and tride upon the jbottoms of the grooves in 1:')assing'- over the intersecting ipportinglthe lwheels and as rails lare depressed or .decline `toward the points of intersecti'omthe tread surfaces of said wheels are carried across'thek-lintersecting` grooves without-jar or pounding. By forming the intersecting rails integral, Iain able to produce a Very strong, rigid and sub- -stantial structure well able to withstand the `jars and vibration to which afcrossingiss ubjected inservice, and by the formation of the tops of the crossing rails at the intersecting points I eliminate all .j ar and pound-I ing andl consequent' vibration,- which ordinarily occurs where the tread surfaces of4 car wheels drop into intersecting grooves in the By forming the tops of crossing yrails.v

and making the bodies of the rails hollow same triangular in cross-section, I lprovide a 4very strong construction which is comparatively light in weight` and Awhich can be easily and cheaply formed by casting in a Asingle piece. By inclining vthe webs 2 all side thrust upon the balls ofthe rails i's taken care of', and by extending the flange' plane occupied by the tops of the ballsof the rails the liability of the guards above the wheelsa leaving the crossing rails` at the intersecting points is reduced to a minimum.

Inthe modified construction illustrated in Figs. 4 and 5, the corners ofthe top'surfaces v' ofthe balls and flange guards are'beveled olf or inclined downwardly at the points where the grooves 5 intersect. This construction obviatcs jar and pounding of the wheels upon the crossing-'rails even when the bottoms of the ange grooves are Worn to a considerable depth.

, 11ok It will be readily understood that minor changesin the size, formand construction' 'of the various parts of my improved crossing can be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claimn 1 i l. The herein described railway crossing comprising intersecting crossing rails formed integral with one another each of which rails comprises a base plate, a pair of inclined webs and a ball and flange guard integral with the upper ends of the inclined webs.

2. The herein described railway crossing comprising intersecting crossing rails each of which is composed of a hollow triangular body portion and a ball and. flange guard surmounting said hollow triangular body portion.

3. -I na railway crossing of the class described, a rail comprising a hollow triangular body portion and a ball and flange guard surmounting said hollow triangular body portion.

4. In a railway crossing of the class cleseribed, a rail comprising a base plate, a pair of inclined webs integral therewith and projecting upwardlyv therefrom and a ball and flange guard integral with the upper ends of said webs.

5. In a-railway crossing of the class described, a rail comprising a hollow triangular body portion, a ball and flange guard integral with the top of said body portion and there being a flange groove between the ball and flange guard.

6. In a railway crossing of the class described, intersecting rails each comprising a hollow triangular body portion, a ball and flange guard integral with the top of said body portion, and the tread surfaces of the balls of the rails being gradually inclined downwardly toward the points where the rails intersect.

7. The herein described railway crossing comprising intersecting crossing rails, each which flange grooves gradually decline toward the points where said grooves intersect.

8. In a railway crossing of the class described, a rail comprising a hollow trian-i gular body portion, a ball integral with the top of said hollow body portion, and a laige guard integral with one side of said bal 9. In a railway crossing of the class described, a rail comprising a hollow triangular body portion and a ball integral with the upper end of said hollow triangular body portion.

l0. The herein described railway crossing comprising intersecting rails each' of which is composed of a hollow triangular body portion, a ball and flange guard surmounting said hollow triangular body portion,

'there being a flange groove between said ball and flange guard, the bottoms of which flange grooves gradually decline toward the points where said grooves intersect and the tread silrfacesgof which balls gradually incline downwardly toward the points of intersection. i

1l. rlhe herein described railway crossing comprising intersecting rails, each of which is composed of a hollow triangular body portion, a ball integral with the top of said hollow body portion, and the top surfaces of all of the balls of the intersecting rails being beveled olf at the corners where said balls intersect.

In testimony whereof I hereunto affix my signature in the presence of two witnesses, this 5th day of March, 19t?.
