To all whom it may concern: j

Be it known that I, BANoRoFT G. BRAINE, a cltizen of the United States, residing at New York city, in the county of New York and State of New-York, havejinvented certain new and useful Improvements in Insulated Rail-Joints, of which the following is a s pecication.

This invention relates to the art` of insutermed rail head extensions projecting be, yond the plane of the sides of the rail head,

and presenting inclined bea-ring faces of materially greater extent than `the area of the under sides of the heads vof standard rails.

The practical ,object accomplished byv this the rail heads, that is to say, to edectuallyz construction, in an, insulated rail joint, is to provide abroad and 4substantial bearing for the insulating material at the under sides of increase the bearing-area for the insulating material with a consequent decrease of the fiber strain, thus enabling the material to better withstand the load imposed.

Hence, as a general object, the inventionv has in view 'a construction which provides for such a bearing for the insulation beneathI the rail heads as to more thoroughly sai`e guard theinsulating material from flowing or. cutting out under the pressure of the load imposed on the rails' by the passing trams, 1t being well understood by those familiar with the art that, in practice, owing to the rela.

tively' small area at the under sides of the standard rail heads, I (at which point thegreatest pressure of the load is exerted), the

insulation is ordinarily -rapidly worn awayl through a flowing or cuttingvaction. It is the intention of the presentinvention to obj viate' this as'much as possible by provlding the rail head.

The essential features of the invention involved in carrying out the foregoing objects are necessarily susceptible to a wide range of structural modification, and toembodiment 1n various forms of joints, without departing from the scope of the invention, but a said lateral extensions at the under sides ofv few .practical applications of the invention areshown in the accompanying drawings, in which- 'x l igure lis aside elevation of one design of `rail joint embodying the present invention. Fig. 2 is a crosssectional view on the lineV 2 2 of Fig. 1. Fig, 2a is a cross-sectidnal view onV the line A-B of Fig. 1. Fig.

3 is adetail view of a rail modified to meet the conditions of the present invention by having united therewith supplemental siderail-sections. Fig. 4 is an end view similar .to Fig. 3 of an integrated rail formation eml bodying the present invention, showing by dotted lines the departure or modification from the conventional lines of a standard rail. Fig. 5 is an' elevation of an insulating end postshapedto conform to the cross section 4of the modified rail-section. Fig. 6 is a cross sectional view of a modiedform of,

joint embodying the present invention. v Fig.

. 7 is a similar view of another form of joint embodying the present invention. Fig. 8 is a similar view of another modification exemplifymg the inventlon.

i Like references designatel corresponding parts in the several figures ofthe drawings.

-ferent ways, but a practical means of securing the desired result is to provide a standard rail or rail-section 1, upon opposite sides thereof, with supplemental side rail-sections or pieces 2 riveted or otherwise rigidly seitself, as plainly shown in Fig. 8 of the under sides of the rail heads and Athereby Athrough-these portions of the rail.

lhead extensionsV 4 afford aV bearing for the at both sides of the joint, as .plainlyshown in cured, as at 3, to the web `of therail so that l the said -supplemental sections constitute in effect a rigid and permanent partiof the rail drawings. The said supplemental side rail sections 2 are of angle formation, the same having vertical portions closely fitting the railsides, and at the upper ends of said" vertical portions being provided with angularly disposed and laterally projecting parts 4 which may, 4be properly characterized as rail head extensions, inasmuch as said parts v4v closely register with and fit against the receive the pressure of the load transmittedv The head extensions of the supplemental rail-sections 2 project laterally from the rail sides to a plane beyond the sides ofthe rail` head and are formed. at their under sides with the inclined extended bearing faces-5 which are of materially greater extent than the area of the under sides of thehead of the standard' rail. 'These inclined extended bearing faces 5 at the under sides of the rail insulating material which may be arranged at the top of the joint bars or splices accord ing `to the character of joint which may be made u in connection, with the modified rail-sectlon. i

To exemplify the practical features of the invention, there is shown in-Figs. 1 and 2 of the drawings a rail jointl of the Well known continuous type and embodying in its or- Tanization the service rails A1--1 modified as described, and theopposite sidejoint bars 6 6. [The side joint bars 6 6 are substantially of the same design as the corresponding bars employed in the said continuous type of rail joint, each of said bars having formed4 inte rally with its foot flange 7 (which over ies the rail base), the bottom base section 8 arranged horizontally beneath the bottom of the' rail and affording a base support therefor; said side joint .bars 6 being further provided at the juncture of the Afoot flange r and basesection 8 with the usual reinforcing and spiking flange 9. VIn adapting the said continuous type of barfs 6, to. the modifiedI rail-section, each' ofy said. bars 6 is further provided at its -top edge withV the vangularlydisposed inclined top bea-ring flange 10 lying beneath the opposing face of the rail head extensions 4, said top .bearing flange 10 presenting. an inclined bearing face substantially paralleling themclined bearing face 5 of the head extension 4gso as to firmly clamp between said two faces the top flange piece 11 yof a side. insulatingsheetf12 interposed between `theI side of the rail and theside-jointbar 6.v The in-y sulating sheet arrangement 12 'is duplicated Fig. 2'of the drawings, and the lower vportion 65 of said insulating sheet is preferably extended continuously labout the base'flange of' the rail'andvbetween such base flange and the Abottom rail receiving portion 7 -8 of the side joint bar. It will thus be seen that in the form of joint described, the insulatingmaterial at the top ofthe said joint bar vor splice member 6 is afforded a broad and substantial bearing at the under sides of the rail heads, which is of greater extent than that allowed for inthe standard constructions where thereis no extension of the under sides ofthe rail heads.

In the form of joint just described, theA same is completed by the employment of the usual series of joint bolts13, and to provide yfor a proper bolt insulation, any of the well applied to the parts associated with one of the rails instead of being associated with with both. Hence, for convenience of illustration, and tosuggest an economical use of t-he insulation,.the joint in Figs. 1 and 2 y is illustrated as having the joint vbars insulated with respect to only one rail, and .only

the joint bolts for that rail provided with suitable linsulating means, but to effectually complete the insulation there iis-employed' an insulating end post 14 interposed between the rail ends, and ofa design corresponding to the cross-sectional design of the modified rail-section. The form of this insulating end post 14 is clearly shown in Fig. 5 of the drawings which illustrates the same as corresponding in shape .to the cross lsection of a rail with the exception lof-.being provided at the underside of its rail head portlon,

with the side inclined head extensionsl which serve to insulate the head extensions 4 of the opposing rail ends in cases where both of the rails are of the modified design claimed herein. j

Another modification of the invention is shown in the joint illustrated in Fig 6 of the drawings, which figure illustrates 'av joint made up with opposite channel bar sections 16 forming the splicemembersin place ,of `joint bars of continuous type Isuch as Sugg '1 gested in Fig. 2 of the drawings. i In other respect`s,'the joint shown" in Fig. 6 is the same4 in construction and function as g the joint shown ,1n F1g. 2, so similar reference connection with a Weber type of joint incharacters will apply toA similar partsin thel j said figures of the drawings. f Arfurther` application of the inventionis j exemplified in Figi` of the drawings illus- V i. -trati-ng ,the modified railfsection "utilized in shoe 17 and the opposite wooderiifiller blocks 18` and 19` arranged respectively 'at opposite sides of the` rails and fitting in the channels formed betweenthe base flanges and the side rail head rtensionsl;` The angle shoe 17 is of the conventional form, the. same einbodying the usual upright sigle bar or girder 20, andthe basev section Cir/base piece 21 extending entirelybeneath the rail bottom or rail base. Also, in the desi-gn ofjoint shown in Fig. 7 an insulatingsheet 22 may be in* terposed between the side joint bar 20 pf the shoe and the adjacent Wooden filler block 18 and lextended beneath the rail base between the latter and the base section 21 of the shoe. ,The joint bolts 23 are provided j with the usual insulating expediente and extend through the'usual bolt holes in the y side joint bar or girder 20, and in the bolt plate or strip 24`arranged onthe outerA side of the filler block 19 which is located at the side of the joint opposite the joint plate 20.

'Y ln this form of joint, in so far as the wooden Fig. 4 of the drawings.

filler blocks subserve insulating functions, the same are provided with extended broad bearix'igs at the under sides of the rail heads.

Another modification ofl the .invention is suggested in Fig. 8 illustrating a joint having at one side a channel bar section 25 with the insulating sheet 12 interposed between -the same and the.` adjacent rail side, and at its opposite side having a wooden filler block 2 6 corresponding in position and function `to the wooden filler block 19 shown in Fig. 7 of the drawings. Also, in said' form ofjoint shown in F ig. 8, the bolts 27 provided `wit-h suitable insulatingmmeans, are arranged to extend through the channel bars 25 at one side of the joint, and at the opposite side of the joint through the wooden filler block 26 and the bolt plate or strip 28 all in the manner well understood by' those familiar with 4the art. f 4

TWhile in the forms of joint already described, the modified rail body is shown provided witli separate supplemental side railsections, it will, of course, be understood that the modified design of rail can be formed integrallyT in the first instance by casting or rolling processes as suggested 1n Also, it .will be understood that in making up a rail joint in accordance with the present invention, either one or both of the rails to'be connected may be of amodified .design without affecting the invention, and therefore various changes in the form, proportion, and arrangementof Darts may be resorted to without departing from the spirit or sacrificinrf any of the advantages of the invention. f
