WILLIAM J'. INFIELD, lOF SAN FRANCISCO, CALIFORNIA.

RAIL 'AND RAILWAY-GOSSING.

To all whom t may concern.

' Be it known that I, WILLIAM J. INFIELD, citizen of the United States, residing at San Francisco, in thecounty of San Francisco andState of California, have invented certain new and useful Improvements in Rails One of the primary Iobjects of the invention is to provide a rail and rail crossing in which the tread of the car wheel is adapted to engage a relatively fiat surface of the rail, and said rail having at opposite sides' flanges, adapted to ,overlie for a consider able distance the sides of the car Wheel, p

to the end that the car wheels in passing over the rail and through the crossing, will travel in a continued uniform plane.

By the present invention, it is designed' to overcome the usual pounding, Jolting and` incident noise in the passage of the rimmed wheels of usual construction over the crossing and thereby prolong the life of the crossing.

t isa further object of the invention to provide a rail and crossing of improved construction, the rails being constructed so as to have oppositely disposed flanges of substantially equal depth, thereby overcoming to a large extent the spreading of the rails and derailing'of the cars. y

Still further, the inventionincludes a rail and crossing, of simple construction, cheap to manufacture, strong and durable, and highly eilicient in operation.

In vthe drawings z-Figure l is a trans verse sectional view taken on lthe line 1 1 of Fig. 2, and showing a pair of the imf proved rails with a pair of the improved ca r wheels in coperative relation with the' rails; Fig. 2 is a plan view of' the crossing and connecting rails; Fig. 3 is a cross sectional view of one of the improved rails, taken substantially on the line 3-3 of Fig. 2.

With mor-'ei particular reference to the drawings, wherein like reference numerals refer to. corresponding parts throughout the several views, the improved type owrail is preferably constructed, substantially as tollows l is 'a base ange, preferably having a dat Specification of Letters Patent.

under surface adapted to engage the cross ties or sleepers of wood, or other suitable 'materiah and 2 is av vertically'extending web arranged substantially midway of the sides of the base l, and connecting with said base l, the upper surface of'which latter lnclines ydownwardly and outwardly, asind1cated at 3, from opposite sides of the web 2 to the outer edge of the base 1. The head of the rail projects at opposite sides beyond the sides of the vertical web 2 and is substantially U-shaped in cross section, whereby to provide a Arelatively wide flat tread surface, 4, and relatively deep side flanges 5.

These side flanges 5. are preferably of the same depth, 'and of like construction, and

are designed to overlie the sides of the wheely for a considerable distance, whereby to prevent accident-il derailment and to provide a smoothv running surface.

The inner surface of the side rims or flanges 5 taper slightly inwardly toward the base, as indicated at 6, whereas the outer surfaces 7, of said side flanges, gradually curve inwardly from apoint adjacent the tread portion 4f, to their point of connection with the web 2 a considerable distance below the tread portioni, to the end that the side flanges 5 are `considerably reinforced against lateral strains by the web portion f2 of the rails. A

It is to be understood that the present construction o, rail is designed more particu larly for use in connection with car wheels devoid of side rimsor flanges, as illustrated at 8, in Fig. 1, with the result that the continuous smooth tread orperiphery of the wheels will 'lie flat upon the tread surface 4.

The crossing to benow described is also of a construction adapted .more particularly for rimle'ss tread wheels, and therail portions of the crossing are of a construction ito constitute, in eii'ect, continuations on the y rails connected therewith, .with the result. that the car wheels, in passing 'from the gaging surface 9 which said surface is in substantially the same horizontal plane with the lji/'heel engaging surface 4 of the connecte' ing rails. .The said surface 9 has projecting upwardly therefrom suitable anges adapted to overlie the sides 'of the car wheel, and

thereby constitute in eect continuations of I the side flanges 5 of the rails. These flanges are so conveniently of the following construction zis a substantially rectangular flange; 11 substantially U-shaped flanges, and 12. V'shaped flanges. These flanges are spaced one from thev other whereby theyform, in the crossing, the intersecting runways of the crossing.

The wheel engaging surface 9 of the crossing is suitably supported upon a base or y body-part 13, and those portions of the surface 9 overlaid on one side by one arm of the U-shaped flange, and at an opposite side by one arm of the V-shapedu flange 12, project outwardly beyond the body portion 13, so as to constitute an extended rail meinber of substantially the same construction asl Athe rail members hereinbefore first described. These outward rail extensions of the crossing have adownwardly projecting central web 14,' connecting with a suitable base 15, and reinforcing portions 16 are 1arranged between the under surface ofthe rail extensions of the crossing'. and the vupper Copies Aof this patent niay be obtained for surface of the base 15,A at the point of connection of the web` portion of the .said e25- .tension 'ith the body portion of the crossing;

'It will be understood that the flanges of the crossing which form therebetween intersecting runways for the car wheels, are of substantially the same design and constructhe-flanges which overlie the wheel en-4 gaging surfaces, the integral rail projec-v tions, and the reinforcing means for the webs may be and preferably are of integralA construction throughout, as illustrated.

I claim 1.. In anintegralrail, the combination of a base portion, a head portionhaving a flat upper surface adapted tobe engaged -by the periphery of a car wheel, a web connecting 1` the head and base portions, saidweb being arranged substantially midway of the sides `of' th'e head and base portion, and side flanges projecting upwardly from-the side l edges of the flat wheel engaging surface of the'head, said side flanges being of a height to overlie a -substantial portionlof the opposite sides of the Wheel 'and the inner surfaces of said flanges inclining outwardly" toward the upper edge thereof.;r

2. Ina railway construction, the combination of a. crossing haying aflat wheel enga ging surface and flanges projecting upwardly from the side edges of said surface whereby to divide the crossing intol intersecting run.'y

and 'integral rall extensions' for said said. rail eX.--

ways, crossing one for each runway, tensions comprising a base part, a head'part, anda connecting web part, said head part having a flat wheel engaging surface in horizontal alinement with the'wheel engaging portion of the crossing, and side flanges to overlie'the sides of thev wheel inyertical aline'rnent with the'side flanges of the crossing runways, the inner surface of said side flanges of the rail extensions 'and the crossing tapering .from the point of connection' with the flat wheel engaging surface to the i upper edge .of said flanges. v

In testimony whereof I aix my signature in presence of two Witnesses.
