My invention'relates to devices for preventing the longitudinal creep of railroad rails, such devices being commonly known as anticreepers, rail anchors, creepchecks or` rail sta s.

ne of the objects of the invention is to provi-de a device of this type.. which will be simple in its construction, inexpensive` tomanufacture, light in weight, strong and `capable of takin a firm and reliable. hold on tlie rail. Anoier object is to provide a device whose grip upn the rail will not affected b vibration, movement of the rail, temporari y, in a directionA the reverse of that in 'which the rail tends to creepl or by anyy other cause tending tov loosen t e grip of anticreepers on the rails engaged thereby. A further object is to rovide a device cony structed in one piece, w ich may be uickly and conveniently applied to the rail y unskilled labor.

The device possesses other features of novelty and advantage, which, with the foregoing, will be obvious from the following description. l

Two embodiments of the invention arg shown in the accompanying drawings, in which: f

Figure 1 is an elevation, with the rail in section, showing the device in position.

Figure 2 is a side elevation, with the cross tie in section, showing the device in position.c

Figure 3 is an elevation, with the rail in section, illustrating the method of applying the device to the rail.

Figure 4 is a perspective vice. A

Figures 5 and 6 are, respectitely, an eleva- -tion with the rail in section and a side elevation with the cross tie in section, showing anview of the-de` other form of the device in place on the rail.

Figure 7 illustrates the application of the device to the rail.

Figure 8 is a perspective view of this form of the device.

The rail A is of the usual construction with a head C, web E and base D, and rests u on crcss ties one of which is shown at B. Tlie anticreeper F is constructed witha portion I adapted to engage the web E, a r- A tion G adapted toengage the tgp ofthe ase D at one` side and a portion adapted to engage the base D at the other side of the rail A, the intervening body portion K serv- Appunti im .ungut s, 11ans'. lserial 116. 66am.

rsuitable implement, applied in the direcment of F toward its propery final gripping ing to connect the portions engaging op- I6 vposite sidesof the rail and as a means of engagement of the anticreeper F with the cross tie B; The several portions are so constructed and relatedthat the anticreeper4 F may be 00 laced in the position, shown by the full ines in Figures 3 and 7 with the portion K transversely below the rail A, the portion I contacting at L with theweb E, the portion'G contacting at M at one side of the base D and the portion H contacting at N at the other` side of the base D; and then forced to the position' shown in Figures 1, 2, 5 and 6 by lows of a hammer, or other To tion of the small arrow P in Figures 3 and 7 or other equally convenient application of force. The anticreeper F will thus be forciblyV moved angularly and transversely upon the rail and will assume successive angular positions, one of which is shown by dotted lines in Figure 3.

The several portions I, G and Hof the anticreeper F are so formed and related one to the other that, in the unstreed condition of F, before application to the rail, the terminal arm H is nearer'to the terminal arm composed of I and G lthan it is after F has been brought'to its proper final gripping position on the rail A. vThe arm H isconstructed with a surface O` arranged to ride upon the lower corner N of the base'D lduring the forced movement of F upon the rail A vso as to strain the anticreeper F from its form when unstressed, indicatedk by the dotted lines in Figures 1 and 5, tothe form assumed in the stressed4 condition in which, it is after application to the rail A, shown by the full lines in Figures 1 and 5.` The form of the surface O is such that the change in form from the unstressed to the stressed con-dition of the anticreeper F is effected gradually andin proportlon to the moveposition; and that the grip of F upon lthe rail A in all intermediate positions on the rail A, `between the initial position shown in Figures 3 and 7 and the final gripping posil f tion shown in Figures 1 and 5, will retain F upon the rail A in any and all such inter-v mediate positions and thus permit a succession of blows applied to F at P, to drive F to its 4final position.

nessun] 'While an excellent lock on the rail is obtained by gripping only the web and .top of the base flange at one side of the rail, and the lower corner of the base flange at its other side, the portion-I of the anticreeper F ma be extended and provided with a surface adapted to engage, when F is in final gripping position, the under side of the head C; so that, in such final position, the portions I and G would be forced in between the rail I head and base and would then seat in what y bar.

is often referred to as the fishing space of the rail A, in a manner similar to the engagement of this space, at the joint, by the fish It will readil i be seen that after the anti- Creeper F has een forced to its final gripping position on the rail, shown in Figures 1,

2, 5, and 6, the portion I, whatever its length,

is :firmly pressed against the web E and the portion G against the base D and. if the portion I is made extended and provided with the surface Q the under side of the rail head C will be engaged and pressed upon. The

rail A is thus firmly gripped bvthe anticreeper F and engagement of the portion H with the base D at the other side of the rail A, eflectually locks the anticreeper F in posi- I tion on the rail A.

' vgagement of the body portion K with the cross tie B will generally be at some distance below the bottom of the base D of the rail A so that any tendency of the rail A to move forward will tend to tilt the anticreeper F and thus increase its grip upon the rail A.

If it is desired `to remove the anticreeper F from the rail A it is necessary to apply force, preferably'by striking the terminal arm H in the direction of the arrow at R in v Figures 1 and 5. Several blows may be necessary. Their e'ect is to produce angular and transverse movement o the anticreeper F upon the rail A in a direction which is I the reverse of that taken in applying the anticreeper to the rail, the successive positions assumed by F in being removed being that shown in Figures 1 and 5 followed by others, one of which is indicated by the dotted lines in Fi ires'S and 7, until the position indicated y the full lines in Figures 3 and 7 is reached when the anticreeper F will fall from or may b e removed with the hand from the rail A.

It will readily be seen that the anticreeper F may be easily and cheaply fashioned from a rolled bar of suitable metal; that it may be applied with ease by unskilled labor; and that, while efi'ectually locked in position so ing from the principles of the invention. Therefore, I do not wish to be understood as limiting the invention to the particular constructions, arrangement and devices shown and described, except so far as these limitations are specifically set forth' inthe claims.
