This invention relates to rail anchors adapted to grip opposite sides of a railroad rail in a position to bear against a stationary part. of the road-bed.

T. Theprincipal object of the invention is to providean improved anchor having a portion for engagement withv a stop surface of the rail at one side thereof and to yield transversely of the rail to permit another part of it the anchonto be moved into resilient gripping engagement with the; other side of the rail the gripping portions of the anchor being so disposed with relation to each-other that the refieXo-f the transversely yielding 16 portion exerts. a resilient grip diagonally through the base portion of the rail from said stop surface to-the lower longitudinal corner. portion of the rail base fiangexat the other side of the rail;

to Another and more specific object of the invention is to provide an improved anchor of. the abovetype in which the jaw end is provided with a relatively long top bearing ex! tending longitudinally of-.the rail and with 21.11 associated portion which yields trans versely of the rail during the application of the anchor, the said bearing serving to hold the bodyportion of the anchor substantially perpendicular to' the length of the rail and to resist any tendency which the anchor: may

have to turn about an axis extending transversely of the rail. r

The invention, more specifically, lncludes an anchor device formed at one end with a shoulder or other suitable means for engagement with the edge portion of one base flange of a railroad rail and formedat the other end with an open loop for embracing the other base flange, the end portion of the loop 7 being preferably formed with a lateral bend adapted to bear against the web of the rail or other suitable stop surface and to yield transversely 'of the rail to permit the first mentioned engaging means to be sprung over 15 the edge of the rail base flange.

The invention is illustrated in one specific embodiment in the accompanyingv drawings, wherein: e

'sumes immediately prior to its final applying: j

The embodiment of the invention shown in the accompanying drawings is made pref-. erably in one pieceand consists of ametal bar 10 formed at one end with an openloop 11 which embraces one base flange of the rail l2 and is' formed at the'other end with an upstanding portion '13 providing a locking shoulder for engagement with the lower corner portion of theother base flange. The portion of the bar 10 extending underneath the rail base is preferablybowed downwardly fromthe bottom surface of the rail, as

indicated by the reference characterl i. This I downwardly bowed portion provides the bearing for "engagement with the vertical face of the cross tie at a substantial distance below-the bottom surface of the rail,

thereby P vi ing a firm tie-abutting mem-"r berwhich will not damage the upper d portion of the tie.

The ends of the bowedportion of the body bear against the bottom surface of the rail base at .16 and 17 when the anchor is in its fully applied position,

as shown in Fig. 2. The loop 11 forms a ion \ able implement.

The distance A (Fig. 4) between the end of the jaw 18 and the shoulder 13, when the anchor is free of the rail, is normally less than the distance B (Fig. 4) between the lower corner 21 of the rail base and the fillet 19. Consequently it is necessary to spread the extremity 18 of the jaw relative to the shoulder 13 to permit the said shoulder to be sprung over the edge of the rail base to its applied position.

In order to provide a rail anchor with the required resilience to permit the anchor to be readily applied and at the same time provide a resilient grip sufficient to resist the longitudinal creeping movement of the rail, the jaw 18 is formed with a lateral loop 22, the end portion 23 of which provides a rela-- tively large bearing surface of the aw, which surface extends longitudinally of the rail base. The portion 23, it will be seen, bears upon the curved surface of the fillet 19 and projects longitudinally of the rail on opposite sides of the body portion of the anchor, as shown best in Fig. 1. This arrangement of the portion 23 parallel to the web of the rail and projecting on opposite sides of the body of the anchor, serves to maintain the body of the anchor substantially at right angles to the length of the rail and also serves to prevent the pressure of the body member against the tie from effecting any substantial rocking movement of the anchor about an axis extending transversely of the rail.

The major portion of the transverse yielding of the anchor during its application to a rail takes place in the bends designated 18a and 22a in Fig. 1. There will also be some resilience produced by reason of the upward flexing or spreading of the jaw 18 relative to the bottom bearing 17. The anchor may be made from a round bar, as shown in the drawings, or from bar or plate material of any suitable crosssection. The shoulder is preferably of a square configuration so as to provide a bearing surface 13a of suitable area to avoid grooving the edge of the rail base flange and also to avoid excessive compression of the metal of the locking shoulder when the anchor is in its ap plied position and exerting its normally strong spring grip transversely of the rail.

The anchor herein shown is applied to the rail by hooking the jaw end 18 over one base flange of the rail, as shown in Fig. 4. The position illustrated in Fig. 4 represents the position of the anchor when it is applied by hand and before any appreciable force has been applied to force it transversely of the rail. The anchor may be forced transversely of the rail to the applied position, as shown in Fig. 2, by any suitable means, for example, by pulling on the shoulder end 13 or by striking the aw end 18 with a suit- By forcing the extremity of the jaw 18 upwardly on the inclined top surface of the rail base, the 100 11 is caused to expand slightly and there y force the bearing 17 of the anchor into tight gripping engagement with the bottom surface of the rail, while the portion 23 of the jaw bears downwardly on the upper surface of the base flange. The resilient pressure of the bearing 17 and the portion 23 on the rail tends to rock the anchor about the bearing 17 as an axis and thereby forces the shoulder end 13 up against the bottom surface of the rail base. The distance between the portion 23 of the jaw 18 and the shoulder 13 is such that when the portion 23 of the jaw is driven into engagement with the web 20 of the rail or any suitable stop surface, it is necessary to flex the anchor transversely of the rail to force the shoulder 13 over the edge of the base flange. This position is illustrated in Fig. 5. When the anchor is in the position indicated in Fig. 5, further pressure on the loop 11 will cause the bends 18a-22a of the lateral loop 22 to flex in substantially the manner indicated in the dotted lines in Fig. 1, that is to say, the portions 18a-22a will be flexed from the dotted line position, shown in Fig. 1, to the full line position, shown in that figure, so as to permit the shoulder 13 to be moved from the position indicated in Fig. 5 to its fully applied position, as shown in Fig. 2. In the last named position, the bearing 16 of the anchor is pressed upwardly against the bottom surface of the rail base by reason of the resilience of the loop 11 tending to rock the body of the anchor upwardly about the bearing 17 as a pivot. When the anchor is in its applied position, a vertical gripping action is produced, by reason of the resilience of the loop 11 pressing downwardly on the top surface of the base flange and the upward pressure at 16 and 17. In addition to this grip, the reflex action of the lateral loop 22 exerts a gripping action diagonally through the base flange of the rail from the fillet 19 to the lower longitudinal corner of the1 base flange at the opposite side of the rai I claim:
