"'My'inventionfrelates ,to devices for preve'ntingthe longitudinal creep of railroad rails, such devices being commonly known as rail anchors, anticreepers, creepchecks or 5 rail stays.

[The principalobject' of the invention is to: provide a device of this'type, which will be simple in its construction, inexpensive, to manufacture, light. in weight, strong and ca '10 pable of taking. affirm and reliable hold upon the rail, A further object is to pro-- vide ,adevice constructed in one .pie'cef'which' may be quickly and conveniently applied to the rail-with the tools usually employed by track mechanics and will not be loosened or become ineffective-by vibrations, movement of the rail temporarilyin adirection the reverse. of that inwhich the rail tends to creep or anyof the other causes tending to loosen the gripof rail anchors on the rails engaged thereby. V I w j My rail anchorpossesses other features of novelty and advantage, which, with the foregoing will be obviousv from the following description. v

7 One embodiment oft-he invention is shown in "the accompanying drawings, in which:

Figure 1 is an elevation, with the rail in I section,'showing thedevice in position. Figure 2 is aside elevation of the same with the crosstie shown in sectioin, Figure 3 is an elevation, with the rail in section,- illus rating the method: of applying the device. I

Figure 4' is a section atthe "plane indi cated by the line AlA in Figure 1. a e

[In ae a a ae. isafra'il 'o' f theusual 'constructiomhavinga base flange C which shown in section atD, V I

The improvedfrailanchorconsists essentially ofia bar Efthe middle portion I of which-is straightand arranged to grip the bottom of the base flange'C; At, each side of thefportion I of the bar E .tie engaging 'portionsK, and L are formed by bending the bar E downwardlyandthen upwardly. One endof the bar Eisbrought to substam retaining portion M; which, when the rail anchorfis in[ position on the rail, will extend somewhat;.above the, bottom of the base of "the rail. The other end .ofthejbar E is made mu hz onge n ands-b n ove o f m a m.

Hjadapted to engage and] grip the upper" surface'of the ,base flange Cat one side of therail. I 1

I In forming-the several portions-of the barE I pre'ferto'form one faceo'f the portion I, gripping thebottom of theb'aseffiange C, and the faceof'the arm'H, gripping the upper surface of'the' base fiangejQ-to be concave as shown at E; at the same'time making: the otherface ofthebar 'E fort-hose" portions convex as shown 'at'G. "If desired 7 a rolled bar having "one" side concave and i the other convex'might'be employed. v,By'so' shapingthe' bottom gripping portion land the arm H, engagement, of each with the base fiangeC is at the edgesQ and Rfor'v the edges 0 and,

jumping off the'rail if repeated blows are necessary to drive it to position. a

The rail anchor is applied to the rail from 7 one side, the arm H engaging the top" of the baseflange'Catjits end only andthelower corner of the base flange C at the other side; 1 of the rail being then'engaged by the bevel end Nj, ancldriving the whole transversely upon the rail until the retaining portion M can reaclrits final posi'tionwithjth'e face engaging the vertical edge of the baseflange (latthe sideppposite to that engaged by the arm jThe bottom gripping portion I' and the arm H- are so disposed with relation the one tothe. other fthat, as'the bar E is forcibly moved @transverselyj upon the rail the edges 0 and P of the arm'I-I ride upon the top of the base flange C and the-edges Q and R. ofthe bottom gripping portion I ride ;upon the bottom of. the base flange-C; and one side of'the base flange of the rail B iswedged in between the arm H and the portion I securely. V v I v i I y In the final position of the rail anchorjon the rail shown in Figures 1 and 2 thebase flangeC is firmly gripped'b-etween the per tionIand the arm H, which, engages and grips the upper surface forv thegreater portion of the lengthof the arm H; and'is held against displacement lfrom' position, by the engagement of thesurfaceSfof theretainin portion M with the opposite edge of the'base flange C. 7

The direction in which the rail tends to creep is indicated'by the arrow in Figure 2. Such creeping movementis resisted and prevented by the engagement of the faces of the portions K and L with the crosstie D; which, by their form, not only provide ample surface of contact with the tie, but also provide contact with the tie D at a considerable distance below the bottom of the base flange C of the rail B. r

It will'readily be seen that by making the bar E relatively wide asshown in Figures 2 and 5 and by forming the faces of the base flange gripping arm H and the bottom gr ip ping portion I to present concave surfaces to the railbase and engage the rail base along the edges Q and R of the portion 1 and O and P of the arm H there is provideda construction in which the pressure is exerted along the "edges 0 and P and Q, and R, tending to flatten the section of the armH and the bottom gripping portion I as indicated in the section at the plane A A in Figure 1 shown in Figure at, where the dotted lines indicated, greatly exaggerated, the shape of the section before the rail anchor has been forced into position and the full lines indicate the sections after being flattened by the pressure exerted along the edges 0 and P of the arm H and Q, and R of the bottom gripping portion 1. The effect will readily be understood to produce a very effective and permanent grip of the arm H upon the top of the base flange C and of the portion I 7 upon the bottom of the base flange C.

To removethe rail anchorfrom the rail, the retaining portion M is forced downward until the lower corner of the base flange C will engage the surface N and the whole then driven transversely of the rail in the directionthe reverse of that in which the rail anchor was forced onto the rail.
