RAILWAY-RAIL.

To all whom it may concern:

Be it known that we, JOHN LUNDIE and WILLIAM R. DUNHAM, Jr. both citizens of respectively, at I the United States, residing, New' York, New York, and New Haven, Connecticut, have invented certain new and useful Improvements in Railway-Rails, of which the following-is a specification.

This invention relates to; railway rails One either for electric or steam railroads, of the obj ects of the invention Is to provide means for seating railway rails upon the wooden ties, theunder surface of the railbase being provided with means for. seating upon and embedding in the tiess In the case of rails under light wheel loads, tieplates are not ordinarilyjemployed, so that under the present invention therail rests directly upon andengages the-wood fibers of the ties. Another objectof the invention is, torprovide an inclined rail with a base so constructed that theline of stress due to the load on the usual beveled wheel-tread passesaxiallythrough the web, and is at right angles to the series of inclined seats on the bottom of the base, the rail being thus held firmly to gage without in any way cutting or injuring the'surface of the These being among the objects of the present 1nvent1on the same consists of certain features Of'COIlSlZIIlClJlOIl and combinations'of parts to'bei hereinafter described,

and then claimed with reference to the ac companying drawings showingtwo embodi- ;;,roads, according to the present invention;

and i fFig, 3. is an underside view of therail showing thegends I only, the intermediate portion being broken away. a

Although the invention is here shown as applied to inclined rails, some of the features of the invention may be capable of use in a'vertical rail. c Referring, to Figs. 1 and2, the rail has a base 10, and a web 11, the web being 'inspecificationof Letters Patent.

clined away from vertical plane. The-rail 1 in Fig. 2 is for steam roads, and has thecustomary head 12.

When thepresentinvention i applied to inclined rails, the entire structure is inclined relatively to the horizontal, plane off/the;

general undersurface'of the rail ba'se,-that is to say, its transverse axis is inclined substantially as indicated by the dottedv line a,

Fig. 1; The vertical is indicated by the dot-;

ted line b.

lows: The undersurface isformed by a se ries of inclined seats-13,preferably connectedby curved portions 14 .In the preferred construction, the seats 13 and the Z connecting portions 14 betweenthe seats, ex-; tend longitudinally of the rail, preferably;

parallel with the longitudinal axis, of the.

rail.

said planes being perpendicular to the in: clined axis a of the rail; Said seats 13, ex-;

Said seats 13 also extend in inclined planes, 7 preferably parallel with each other, i

cept for small seating portionswhich may.

' be at the edges of the base of the'rail, are

both of substantially the same width. In

Fig. 1, the dotted line 0 indicates the direc-- tion of inclination of the seating or step surfaces l3-transversely of the rail, while'the. dotted line (Z is a line substantially parallel withthelongitudinal axis of any tie. j The car wheel 15. is of the usual beveled or stand-,-

ard type, having abeveled tread'16.,

It will be seen from the preferred forr'n ofthej invention that the seating surfaces 13 are the majorseatingsurfaces of,the,rail,: and thatthey offer more resistance to the, seating of the rail inthe top of a woodentie than the connectingsurfaces 14, which,

lie at a greater angle of inclination to-the; plane of the base, or top surface of the tie,

and which may be said to constitute minor seating surfaces.

From the above descriptionof the pre-,.

ferred form ofthe invention it will be seen that the line of pressure-in the wheel and the line of stress in the rail are co-incident,.;

being represented by the line a. It' will also be seen that the tread of ithe wheel and the;

bearing surface therefor of the rail are substantially at right angles to the line a, at any point along the rail over which the wheel is passing. It will also be seen that if the left-hand end of any tie be considered the outside of the track, the shoulders or surfaces at 14 will be at those sides of the. successive seating surfaces 18, excepting the I.

last one to the right, which are away from that end of the tie. It will also be seen by the arrow indications in Fig. 1 that the re- 1 sisting forces of a tie are at right angles to the direction of seating, thus preventing slipping- The action may be described in the following terms,-so far as the preferred embodiment of the invention is concerned:

The line of stress a, due to the load on the usual beveled wheel tread 16 passes axially through the web, and is at right angles to the series of inclined seats 13 on the bottom of the base, such seats being parallel with the bevel of the wheel tread, so that the rail is held firmly to gage. It will be seen that the described undersurface of the base will not, in anyway cut or injure the surface of the tie, as it merely becomes slightly embedded therein,'due to the preferred shallow or slight depth of the ribs, the fibers I of the tie accommodating themselves to the contour of the said under surface.

' In one aspect the under surface of th base of the rail may be considered as developed in waves, the crests of which at 14 "and the intermediate troughs of which extend in lines substantially parallel with the longitudinal axis of the rail; and preferably, the so-formed ribs are defined by planes, joined by curves at the juncture of *neighboring ribs and at the edge of each and it is believed unnecessary to specify just what objections to vertical rails of the type referred to are overcome, when the invention is applied to inclined rails.

' It is obvious that the invention is susceptible of more or less modification,as, for instance, it may be applied to vertical rails,-and that such modifications would still be within the appended claims.

WVhat I claim as new is:
