Patented Aug. 18, 1931 vUNITED `STATES MCLEOD THOMSON, OF CHELSEA, NEW JERSEY RAILWAY RAIL V'This invention relates to a novel construction for Vrailway rail and rail splicing means having special utility in its application to the q. heavier deep-girder type of rails. v Y Because of the heavy rolling loads and high speed loads to which modern railway track is subjected the tendency among railroad engineers is to adopt and use very heavy rail q, ranging from 130 lbs. to the yard upwards and as the height of such rail increases new conditions naturally are set up with respect to the splicing of such rail by the rail oints.

The higher the rail' the more desirable it becomes to have a splice bar anchorage at a point other than immediately beneath the head of the rail or in the head fillet thereof because of the fact that the higher rails will be decidedly stiffer and have a greater moment of inertia so that the ordinate of deflection will be less at the joint so that it will not be necessaryto use the full space between the head and base of the rail for adequate splice bar anchorage. mn. Accordingly, the present invention has in 5 view a novel form of rail construction wherein the splice bar anchorage on the rail can be made at a point intermediate the head and base of the rail while at the same time permitting the rail construction having desirable and advantageous attributes as to better working in the mill, better and more uniform cooling and a better construction for car wheel flange wear.

With these and other objects in View which will readily appear to those familiar with the art, the invention consists in the novel construction, combination and arrangement of features hereinafter described, illustrated and claimed, and certain preferable embodiments, by way of example, are shown in the accompanying drawings, in which Figure 1 is a sectional view of a rail and a pair of splicing bars illustrating the primary feature of the present invention, the 45. view showing a rail joint of the fillet bearing type.

Figure 2 is a view similar to Fig. 1 showing a rail oint of the head fishing type.

splice bar anchorage, that is, such anchorages being arranged on the web above and below the line of the bolt holes.

Figure 4 is a vertical sectional view showing a half rail section wherein the bar engaging rib may be located near the base of the rail web while the head of the bar engages the underside of the rail head. f

In carrying forward the present invention it may be said that the improved rail construction is intended to retain all of the desirable advantages of the novel railway rail construction covered by the U. S. vpatent to W. P. Thomson, No. 1,507,870,.dated September 9, 1924, particularlywith reference to a having the design of the rail head of such form and character that in the process of rolling the metal can be manipulated tothe very best advantage, as well as providing for an effective and uniform cooling of the rail body, and also linvolving a distribution of metal which may be utilized to either actually reduce the weight of the rail or to permit the equivalent of themetal removed to y be placed at more advantageous locations yHI elsewhere in the rail. Furthermore, the present invention provides a novel Vrail design which not only lends itself readily to a successful carrying forward `of the Headfree splicing structure of thev Thomson Reissue Patent No. 15,773. but also lends itself to utilizing any practical form', of splicing structure that may effectively be utilized in the space provided therefor between the splice bar anchorage on the web and the rail base flange. y

To illustrate these features of the invention reference is first made to Fig. lof the drawings wherein there is shown the novel rail consisting primarily of the head l, the base 2, and the intermediate connecting web 3. l For purposes of illustration therail selected for this view 'of the drawings is a 150 lb. R. E. rail and on account of the great height of this rail and the deepgirder char- P5 acteristic thereof ythe improvements contemplated by lthe present invention can be very well adapted thereto. That is to say, according to the present invention it is primarily proposed to form on the side of theV web,

below the rail head, an outward or lateral reinforcing protuberance or rib 4 formed at its underside with a joint bar bearing 5. In the example being described this splice bar 5 bearing may have the form and characteristic of a rib having a fillet adjoining and merging into the web 3 of the rail and adapted to form a fulcruming anchorage for the upper inner bearing corner 6 of the joint 10 bar 7 having its foot 8 adjustably fitting the upper inclined side of the .rail 'flange to permit of adjustment for wear in the same manner, and for the same purpose as provided for in the head-free type of joint described in the Thomson Reissue patent above referred'to. In the high type of rail `referred yto the full fishing-.space between the head of the rail and the base of the rail isnot necessary to be ntilized for adequate splicingpurposes, and con- .29 sequently the present invention provides such adequate splice by inter-posing a joint bar between t-he rail flange and the intermediately located splice bar anchorage 4 which may be of any suitable form, according to require ments,` just so long as it provides a substantial abutment'projection against which the joint bar or splice bar is seated.

yThe type of joint bar is Vnot an essential feature of the present invention because while the fillet bearing type of joint is shown in Fig. 1 of the drawings, the head contact type of joint'bar may be employed as shown in Fig. 2 of the drawings, said head contact type of bar being designated by the reference number 9 and having a .flat top fishing survface 10 engaging the flat fishing bearing 11 formed .at the underside `of the lateral protuberance or abutment projection 12 formed with .and projecting laterally from; the web of the rail at a pointbelow the .head thereof. A .By way of showing the range of modification that may be resorted to in the number and'location of `the splice bar anchorages reference is made to Fig. 3 of `the drawings wherein a lateral protuberance or abutment projection 18 is projected from the side of the web above the bolt holes and a corresponding lower protuberance or projection 19 Vis formed on and projects from the web below `the line of the bolt holes. In this suggested form of the invention a splice bar 20 may be provided at its upper and lower inner corners with the rounded bearing

corners

21 and 22 which respectively engage with the ishingbearings formed on the abutments or

anchorages

18 and 19. Also, while the invention with respect to the splice bar anchorages on the web may be embodied in connection with any. form of head construction Vof the rails, -a preferable form of head construction is shown in Figs. 1 andv 2 of the drawings wherein the. lateral bottom portions of the rail head-are concaved or recessed as at 23. This construction of concaving or recessing the lateral bottom portions of the rail head permits of a novel distribution of the metal to permit the addition of more metal to the wearing surface of the rail or otherwise utilizing the removed metal either for actually reducing the weight of the rail or placing the equivalent of the removed metal at more advantageous locations. vThis constructiomas wearof the rail takes place, provides more free space for the Ylower edges of the wheel flanges. and as this rail cannot wear-toi a shelf on the high side, there is consequently less train resistance because a rolling friction is provided insteadof a sliding friction.

By reason ofther location of the splice bar anchorage on the rail V.web it .Will .beappasrent that reinforcing metal may be built .up on the head of the splice `bar without interference with the car wheel flange.

Fig. 4 of the drawings illustrates .another example ofthe application of the Y'invention wherein `a standardjoint bar 7a visl applied to a rail having a standard he'ad so that 'the head ofthe bar takes the'usul bearing while the foot of the `bar bearsagainstthe rib 19d on the web of .the rail near the base and below the line of thc bolt holes. Thus it will b e apparent that the present vinvention-contemplates the use of a rail-.reinforcing splice bar anchorage on the rail web whichmay'be located near the head of therail .above the line ofthe bolt holes as in Figs. .1 an d 2,ior near the bottom of the rail .below the Aline ofthe bolt holesas in Fig. 4,.V or that a dual web-anchorage may be provided as shown bolt'holes.

`While the illustrations shown inthe draw-v ings show the applicationsofthe'invention to a `headfree rail constructed in accordance with the patents previously referred-to,

In .other wordsfaprimary landfdistinctive object of the present invention resides in providing an anchorage on the web ofthe rail for a splice bar, the saidanchorage radiating from a .point o11fthe rail-webbetweenithe head .and .the base of the: rail and preferably above or/ and belowl the line-ofthe bolt holes. Itfwill, thereforefbe understood that the present invention provides a splice bar bearing or engaging vsurface or surfaces radiatingfrom a point or points on the rail web above orbelow the, horizontalneutral aXis of the rail. i
