To all whom itmay concern:

Be it known that I, Rommns A. Bum, a citizen of the United States, residing at Fort Wane, in the county of Allen and 5 State'of ndiana, have invented certain new and useful-1m rovements in Rail Anchors, of which the ollowing is a specification.

My invention relates to devices for preventmg the longitudinal creep of railroad 10 rails, these devices being commonly called rail anchors, anti-creepers or rail stays.

.One of theobjects of myinvention is the provision of a .rail anchor of simple and compact construction, requiring a minimum 16 amount of metal, inexpensive to manufactime, which will maintain a reliable holdon the rail as against thextendency of the device to become loosened by vibration or other disturbing influences, and which may be 20 uickly'and conveniently ut in place on t e ra l, or removed there em, if occasion further object of my inventionis the provision 0f1a 'rail anchor so constructed,

feral times without impairing its holding I power.

It is another ob'ect of my invention to increase the grip o the device on the rail ltzisanother ob'ect ofmy invention to rovide a rail" am or so, constructed that 6.5 it will have a very substantial and efiectiye foot-piece to'bear against the sideofa tie,

or the like, without,"how'ever, appreciably increasing the amountof-nie'tal in the de- (iiknotherl h nst ea' rai -anc or so co rn cannot be accidentally off the rail also so constructed that there w ll be no parts projecting any substantial distanceat object of invention is to prothat it may. be removed and replaced sevthe longitudinal creep of railroad ,rails in;

my invention is the obliquely on the rail base or'to tilt out of its normal vertical lane will only serveto cted that it' bein eda advw .engagethe'respective top either end of the device, above the rail base flanges to cause an obstruction.

A further ob3ect of my invention is to provide av ra l anchor havin all the advantages abovenoted and wxich maybe formed in one piece from a bar of resilient material.

The invention consists in the novel constructions, arrangements and devices to be hereinafter described and claimed for carrying out the above-stated objects and such other ob sets as will appear from the-.follow ng escriptlonof a preferred embodirnent illustrated in the accompanying drawm s wherein,- Y

Fig. 4 is end elevationalfview of theanchor showing it positioned ,on' the'railbase and against a tie. v 1

Like characters of reference designate like parts in the several views;

Referring now to the draw' i will-be noted, that the embodiment erein illu'strated isformed of'a' bar of resilient steel formed so as to provide a strai l t-portion 8 adapted to extend transverse y under a rail base and having at one end an upwardly extending return .dissosed arm 9 and at its otherend an upwar ly extending angularly disposed arm 10; The arm 9 is provided with a the end-wall 11 of which provides a bead surface adapted to enizge the vertical ge 12 of the rail base nge 12.- The. upper wall of the said recess is defined by an inwardly extendiiifi relativelylwide lip'13.nnd the lowerfw v is definedflby a -narrow lip 14,- saidjlips and t'tom surfaces 12-ma 12- of the base" flange 12 when? tiled-device 'is' in gripping osition on'the The arm 10 is provided with a recess having a bearing surface 15 which is adapted to engage the verti-- cal edge 16 of the rail base flange 16. The arm 10, above the surface 15, 18 provided with an inwardly extending lip 17 which is adapted to engage. the top surface 16 of the base flange 16 when the device is in gripping position on the rail. The arm 10 on its inner side below the bearing surface 15 is also rovided with an inclined surface 18 whi is adapted to ride over the edge of the rail base flange 16 as the device is applied to or removed from the rail, as will be resently explained.

e several parts of the device are so formed that the normal distance between the bearing surfaces 11 and 15, represented by the line :12 Fi 2, is considerably less than the width of t e rail base to which the device is to be applied, while the distance between the inner edge of the lip. 17 and the bight 19 between the arm 9 and the transverse portion 8, represented by the line 3 Fi 2; also the distance between the inner f ce of the lip 14 and the bight 20 between the arm 10 and the transverse portion 8, represented bv the line 2 Fig. 2, are eater than the width of the rail base to w 'ch the device is to be applied. The lines :12 and z are applied to the full-line representation in Fig. 2, whereas line y is applied to the dotted line re resentation to more clearly show the len indicated by this line with relation to t e widthof the rail-base.

In a plying the device to the rail the device is rought into a position substantially as shown in dotted lines in Fig. 2 with the arm 9 hooked over one of the rail base flanges, in the present showing over the base flange 12, the edge of said base flange extending into the bight 19. "The lip 17 will now readily clear the outer edge of the base flange 16 so that the end of the device carrying the arm .10 may be raised to bring the transverse portion 8'substantially parallel with the rail base. The device may now be shifted laterally on the rail base to bring the edge of the base flange 16 into the bight 2O whereupon thelip 14 will clear the edge of the base flange 12 in the manner shown in full lines in Fig. 2, so as to permit the device to be moved to the dotted line position of Fig. 3. By striking the up er end of the arm 10 with a sledge or the li e, the end of the device carrying said arm 10 ma be forced down, the inclined surface 18 riding down over the edge 16 of the base flan 16 forces the arms 9 and 10 apart until the aring surface 15 engages the vertical ed e 16 of said base flange and the recessed en of arm 9 is in firm engagement with the to, bottom and vertical surfaces of the base anti: 12, the final position of the device on rail base being as shown in full .quently, increase their 1,eea,71a

lines in Figs. 1 and 3. In Fig. 4, the device is shown as abutting against a tie 21 and being adapted to prevent ereepa e of the rail in the direction indicated by t e arrow.

The upwardly extending arms 9 and 10 are quite short and since the distance between the bearing surfaces 11 and 15 is substantially less than the width of the rail base, it will be obvious that the device, in being applied to the rail, is placed under a very considerable tension or strain, consequently, the arms exert a powerful grip on the edges of the respective rail base flanges. As the end of the device carrying the arm 10 is forced down relatively to the rail base, the inclined surface 18 in riding over the edge of the base flange 16 tends toproduce a furrow or groove in the base flange and interfitting vertical ridges and grooves are formed in the co-engagmg surfaces of the bearing 15 and the edge of said base flange. The powerful grip of the device on the rail and the character of the coengaging surfaces of the bearing 15 and the base flange 16 are ample to prevent any slippage of the device longitudinall of the rail in either direction notwithstan ing the disturbing influences to which a device of this kind is subjected such, for exam le, as the passage of heavy rolling stoc and changeable weather conditions. It will be obvious that any tendency of the device to be forced obliquely on the rail base will only tend to increase the distance between the bearing surfaces 11 and 15 and, conseip upon the edges of the respective rail fise flanges. Since the lips 13 and 14 enga e the respective top and bottom surfaces 0 the base flange 12 and the lip 17 engages the top surface of the base flange 16, all tendency for the device to tilt out of its normal vertical plane is reduced to a minimum. However, any tendency for the device to tilt out of its vertical plane must necessarily be accompanied by a tendency for the lip 14 to ride up into engagement with the vertical edge 12 of the base flange 12 which would produce a greater strain in the device due to forc' further apart the bearing surfaces 11 an 15 with the consequent result'that the devic'e gxerts a greater gripping action on therail ase.

The device is of very simple and compact construction requiring a minimum amount of metal and may be inexpensivel manufactured in one piece from a bar 0 suitable resilient metal. The device is adapted to prevent longitudinal creep of rails in either direction. t may be applied on a rail base from either side, in other words, it is immaterial which flange of the rail base the return disposed arm 9 is hooked over. The device can only be applied to a rail in one way and it may be conveniently, quickly fee a any fallin ums and re rl a lied b an ordinary track labor 'br b iipa ibl otf a spike. The device may be readily removed from the rail by forcing upwardly the end carrying the angularl disposed arm 10 which may be done eit er by prying upwardly that end j of the device while the rail .base flange 16" is tap ed with a hammer adjacent the arm 10 or y striking theunder side of the left end of the device with a sledge or the like.

The device may be reapplied to a rail, in rfact, it may be remove and replaced several times without impairing its holding power.

- It will'be noted that the transversely extending portion '8 of the device is disposed a substantial-distance below the base of the rail, in other .words, there is a substantial space between the upper side of the portion 8 and the under side of the rail base, which arrangement results in a substantial and effective footpiece to bear against the side of the tie and which is obtained with practically no appreciable increase 'inthe amount 25 of metal in the device; No part of the device projects any substantial distance abovethe rail base flanges; therefore, the device oflers practically no obstruction to interfere with track-work or over which trackmen or trainmen mightstumble. The device cannot he accidentally knocked ofi the rail by object or a misapplied blow from a sle ge as in driving a nearby spike,

' because in loosening the grip of the device on the rail the force must be such as to rearm 10' being to the rail base.

I do not intend tolimit m invention to the details-of construction s own and described, exce t only in so far as certain of the appende claims are specifically so limited, as it will be obvious that modifications may be made without departing from the principles of my invention.
