"5'Claims; (01. 238- 327) This; invention relatesta improvements in'rail anchoring devices, and particularly to. anchoring devicesadaptedto cooperate with arailsupporting element to. prevent "lengthwise movement. of

therail. relative tosaid supporting element.

One,...oithe..obiects.of the invention is to pro:- vide improvementsl-in devices of'the .above' char.- acterwhich make.it.practicable' to provide a twoway,.anchor device constructedito exert" itsprincipal g'rip. on the; railfdiagonally through the 'ra'il base from the lower webfillet' at one side OfIIth'e rail to the outer edge of the rail base..flang .e; at the. other. side. of; the,rail, and to also extend into thesspacelbetween; the. rail." basei anfdthe top surfaceoi an. underlying cross tie soas to embrace ingly engagethe. forward and rear edge portions or a tie, plate. interposed. between the rail":an d. the crossitie.

any form of retaining members; such as screws;

flexible spikes, and/or clips may be used; The

width of tie plate I2, as herein illustrated, is

somewhat less than the width of the cross tie Consequently, there are spaces designated 1. l8 and I9, as shown best inFig. 3, intervening between the bottom surface of the rail base Ill and the top surface of the cross tie H adjacent the forward and rear faces of the tie plate |2.

The rail anchor device, as illustrated in Figs.

tends to increase the spacings between the under A

rail body portions

22 and 23 and thereby facilitates application of the anchor device to oversized tie plates. The application of the anchor device to the base flange of the rail also effects a slight spreading of the jaw. 2| relative to the

transverse body portions

22 and 23 and thereby effects a vertical gripping action between the end of the jaw 2| and the under rail body portions ofthe anchor device, which gripping action is uniform in relation to both under rail body portions. This vertically exerted force serves, in addition to resisting the creeping movement of the rail to 5 hold the locking shoulders 28 and 29 in their lockto 5, inclusive, is made from a metal bar of general rectangular configuration which is of greater 3 width than thickness and formed with one of its narrow faces rounded as indicated by the reference numeral 20. The said bar is formed with a substantially straight bearing'portion midway between'its'ends and isbent to provide a relatively long bowed; portion and spaced arms 22.

and 23. The bowed portion 2| constitutes an upper jaw of the anchor device and the rounded surface as the substantially straight central portion of the bar is adapted to bear against the fillet 24 at the junction of the web of the rail extend across beneath "the rail base and abut against theforward and rear edges of the tie plate l2 within the spaces l8 and I3. *The' ends of both'under rail body' portions of the anchor are offset upwardly, as indicated at 28 and 29, so as to provide locking shoulders for engagement with the'lower longitudinal edge of the rail base.

Iniapplying the anchor device to the rail the shoulder ends of the

body portions

22 and 23 are passed beneath the rail until the hook-shaped jaw portion 2| engages the top inclined surface of the rail base. This position will be assumed before the locking shoulders 28 and 29 engage over the other edge of the rail base. The jaw portion 2| of the anchor is then forced upwardly on the rail base to bear against the fillet 24. This force is preferably applied by striking the

bends

26 and 21 of'the anchor device with a track sledge or other suitable implement. Duringthis applying movement the bowed jaw portion 2| will be flexed substantially throughout its full length so as to permit the under

rail body portions

22 and 23 to move transversely of the rail base a distance sufiicient topermit the lockingshoulders 2 8 and 29 to snap up over the other edge of the rail base. The said application of force also tends to flex the

large bends

26 and 21 transversely of the rail to some'extent so that the combined resilience of the

bends

25 and 21 and the bowed jawportion 2| exerts a resilient grip on the rail which extends diagonally through therail base from the fillet 24 to the lower corner of the rail base flange at the other. side of the rail. The length of the jaw 2| is such that it can be positioned edgewise against the fillet 24 and flexed transversely of its greatest width a distance suflicient to permit the application of the anchor device to rails having oversized base flanges. This flexing of the jaw 2| transversely of the rail also ing positions. a Referring. now to the modified embodiment shown in Fig. 6: The modified anchor device, for the most part, may be and preferably is identical with the constructions of the previous embodiment. Theonly difference beingthat instead of forming the free ends of the under rail body portions with offset shoulders, as indicated in Fig. 1, the free ends of the body portions designated 30 and 3| are bent to form return hooks 32 and 33 adapted to engage over the upper corner portion 34 of the rail base flange. The combined flexing of jaw 2| and the

bends

26 and 21 of the modified anchor device permit transverse flexing of the anchor sufficient to apply the return hook portions 32 and 33 over the upper corner 34 of the rail base. While the invention is illustrated herein in connection with certain conventional rail base and supporting structures, it will be obvious that the anchor device can be constructed to accommo date supporting structures of various character. It will also be obvious that the embodiments of the invention herein shown may be otherwise varied in construction without departure from the spirit of the invention. Consequently the invention is not to be limited by the specific constructions shown and described exceptwhere those constructions are included in the claims.

We claim: 7 r

1. A unitary device adapted to cooperate with a railroad rail supporting structure to resist both forward and rearward movements of the rail relative to said supportin structure, comprising two body portions for extending transversely of the rail beneath the base thereof and a connecting bar for connecting said body portions; the said body portions being positioned to abut against opposite faces of the said rail supporting structure and provided with means for locking engagement with the rail, and the said connecting bar being positioned to extend lengthwise of the rail across said rail supporting structure and formed with a rounded edge to bear against a curved fillet at the junction of the web of the rail and the base portion thereof and beingformed also with a straight portion midway between the bodies and bowed toward the rail so that the said bar will bear only against the said fillet at the location of said straight portion.

2. A unitary device adapted to cooperate with a railroad rail supporting structure to resist both forward and rearward movements of the rail relative to said supporting structure, comprising a bar of greater width than thickness having a rounded surface along one longitudinal edge thereof and a fiat surface along the opposite edge and bent to form two body portions for extending transversely of the rail beneath the .base thereof and a connecting bar for connecting the ends of said body portions at one side of the rail;

the flat edge of the bar in the said body portions being positioned to abut against opposite faces of the said rail supporting structure and the said body portions being provided with means for locking engagement with the rail, and the said connecting bar being positioned to extend lengthwise of the rail across said rail supporting structure and bowed toward the web of the rail and positioned for bearing engagement of said rounded surface only at a location midway between said body portions, against a fillet at the junction of said web and the base portion of the rail.

3. A unitary device adapted to cooperate with a rail supporting structure to resist both forward and rearward movements of the rail relative to said supporting structure, comprising a bar of greater width than thickness bent to form two body portions for extending transversely of the rail beneath the base thereof and a connecting bar for connecting said body portions; the said body portions being positioned to abut against opposite faces of the said rail supporting structure and provided with means for locking engagement with the rail, and the said connecting bar being positioned to extend lengthwise of the rail across said rail supporting structure and formed with a rounded edge to bear against a curved fillet junction of the web of the rail and the base portion thereof and being formed also with a straight portion midway between the bodies and bowed toward the rail so that the said bar will bear only against said fillet at the location of said straight portion.
