STEEL COMPANY, A CORPORATION OF'IPENNSYLVANIA RAIL ANCHOR Applicatian mea December 1,1930. semi No. 499,277.

invention relates to rail anchors and particularly to a one-piece double-acting type provide a rail anchorVv which is easily applied to a rail, which efficiently grips the rail base lia-nge to retain the anchor in operative position on the rail and which cooperates with a stationary member of the roadbedV to prevent the rail from creeping. Another object of my invention is to provide a rail anchor which is applied to va rail. road rail by distortion and which will be held in operative position by the'tendency of the anchor to resume a condition from which p '20 it was sprung when applied to the rail. Y

VA further object of my invention is to provide a one piece railv anchor which isadaptable to rails having base anges of dierent widths. Y. r f

Another object of my'invention is to pro-v vide a rail anchorwhich will check the longitudinal creeping of the rail in'either direction of traliic.

The novel features of my invention will be more fully understood from the following description and claims taken with the drawings in which:

Fig. 1 is a plan view of one form of my improved anchor. f

Fig; 2 is a view of a portion of a railroad rail,a cross tie supporting theraiha spike securing the rail to the tie and the rail anchor' in its initial and operative positions on the rail. Y Y

Fig. 3 is a view of the right hand end of the anchor as shown in Fig. 2.

Fig. 4L is a section taken on line l--Lifofl Fig. 2. .y Fig. 5 is a view of the left hand end of the anchor as shown in Fig. 2. y

Figs. 6,74, 8, 9 and 10 are similar to Figs. 1, 2, 3, 4, andl 5, but illustrating a modilied Y construction of the anchor. f l

Referring to the drawings: 14 designates 16 a tie plate, 17 a spike,

and '18`and 19 the vrespective forms of rail anchors. p

1n the embodiment of my invention shown in Figs. 1' to 5 inclusive, the anchor comprises end members 21 i connecting member 23-which is adapted to bridge a tie. y Y

Y Theranchor is preferably made fromva bar of resilient metal of uniform section and its

ends

21 and 22 are formed with,

notches

24 and 25 to provide shoulders or

vrailengaging members

26 and 27. -The said members are formed so as to engage the bottom of one of the rail base flanges.

The -connecting member23 is preferably i formed with a/pocket or depression 28 which is adapted to pass yover the Vh ead of a spike but out of gripping engagementwith the up- Y y er surface thereof, so that the depending portion 30 will engage the rail adjacent the spike andthe anchor will fulcrum on the rail base and not on the spike head. Y The ortioni() also functions to engage the sides of the spike head upon ythe rail tovmovelongitudinally,v and to engage the inner edge of the spike headupon the tendency of the anchor to move laterally of the rail so as to prevent the dislodgment of the anchor when it is in its operative position.V A v The anchor is applied to a rail by hookingits end 21 over the flange ofthe rail so that the' shoulder 26 'engages the under surface of the rail base and bringing the pocket-28y overv the head ofthe spike so'that the portion 30 is' in engagement with the upper surface of the lrailvbase liange. `The anchor is now in the position indicated by dotted lines in Fig. 2. Pressure is now applied to the other end of the member 23,'such as by placing the foot thereon, 'and a downward Iblow is struck with a hammer at the point indicated by the` arrow in Fig. 2. kThis will cause the shoulder 27 to be brought into engagement with the under side of the rail base, having entered the notch 24C. yThe

shoulders

26 and 27 willnow be in gripping engage` ment with the under surface of the rail base flange and the portion'. 80 is in ygripping engagement with the upper surface of the rail and 22`and an intermediate the tendency of l the rail base flange Vand modiiications Without -I claim as new and desire base fiange due to the tendency of the anchor to resume its original condition before being sprung onto the rail.

In Figs. 6 to l() I have illustrated a modified embodiment of my invention. In this modification the general features and principle of action and application are the same as for the anchor shown in Figs. 1 to 5 1nclusive, the principal difference being the manner inwliiclithe fulcrum is formed on the member 35, and also that modified means are provided to prevent longitudinal Yand lateral movement of the anchor. v

In this case the member 35 is depressed at 87 to form the rail base engaging portion 38 and the bar is further depressed at 39 to provide a tongue 86 which is adapted to enter an aperture in the tie plate 16. The ends 40 and il are formed With notches 42 and 48, respectively, to provide rail engaging members or shoulders iii and 45, respectively, which are adapted to engage the bottom of the rail adjacent the edge of one of the rail base flanges.

The method of application of this-modified form, as shown in F ig. 6, is substantially the same as for the form shown in Fig. 2, that is, the end 40 is hooked over the rail base flange with the shoulder la engaging the under surface of the iange, the tongue 36 is inserted in the aperture il@ and the rail engaging portion 38 is brought into engagement with the upper surface of the rail base flange. The anchor is now in the position indicated in dotted lines in Fig. 6. Further application of the anchor is identical With that for the form shown in F ig. 2.

From the foregoing description it will be obvious to those skilled in the art that I have devised an improved one-piece rail anchor which is simple in construction, easily applied to the rail base and efhciently grips same-to check the creeping tendency of the railin either direction of travel. My device is particularly adaptable to rails having base iianges of different Widths as it grips only one side of the flange of a rail its gripping ability is not affected by changes in Widths of base flanges.

Another feature of importance is the fact that the anchor does not depend upon any member of the` roadbed for its gripping effect 'on the rail.

IVhiie I have shown my invention in a plurality of forms, it Will be obvious to those skilled in the art that it is notV so limited, but is susceptible of various other changes departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.
