T o all whom t 'mayConcern.'y n Be it knownthat I, HonAToiG. GVILLMon, a citizen ofthe United States, residing at IVashington, in the District of Columbia, have invented certain :new anduseful Im-y provements in Anticreepers,"oiwhich the following is a specification;

vMy invention relates to devices Ator preventing the longitudinal creep of railroad rails, such devices being-commonly known asanticreepers, rail anchors, creep-checks' or rail stays.

The principal object of the invention is to provide a device o'l' this type which will be simple in its construction, inexpensivetoV manufactura l light `in weight, strong and capable of taking'a lfirm fand reliable hold on the rail, which` willnotbe aiiectedrby vibration, movement of the railteinporarily .in a direction the reverse of that in which the rail tends tor creep or any other cause tending to loosen the grip of anticreepers on the rails engaged thereby.`

A: `further Objectis to providefav'device constructed in onefpiece whichl may be quickly and conveniently applied to the rail with Ithe tools usually employed by track The device possesse'sfother features of novelty and advantage,` which, with the foregoing, will be obvious from the followparts in the several figures ofthe drawings.

In the embodiment of the invention illus- .tra'ted in the drawings the rail A rests upon crossties, a portion of one ofwhich is shown and indicated by B, and is ofthe usual construction with a head C and a base D. 'Ihe anticreeperE is constructed withVK a surface F adapted to engage the under portion of the'rail head GandV a suraceG adapted to .engage the upper'surface of-the rail base D at one side ofthe rail A, anda surface I-I adapted to engage theedge ofthe rail base at the lother side the rail A. lThe Vportion ILofthe anticreeper E,Vupon which are the surfaces `Gr `and F, is Iadapted to beforced into the ishingspacebetween the' head C `and baseD ofthe rail vA andthe portion-K of the anticree'per upon which isthe surface is adapted V'to be positionedoutside' the" base D of the rail Aopposite the por, tion I. The upper freefen'ds of the'portions I and"K of' the anticreeperE Whichfare substantiallyparallel to each other, are con,-l

nected the one to the other by rcurved lporftions L and M anda `straighttransverse portion'N, Aeither of thefaces OorPQof which is "adapted to engage with thelcrosstie Br .The portion K,`the curved portions L and M and Jthe transverse portion N are so formed vandf relatedfto each" other as to permit the Vanticreeper E.V to receive' the rail base D between the curved portion L and the portion Kl `and allow the end R of the portion K to lbebroughtabove the rail', base `D vand also toreceivefthe rail base D between the curved portion M,l`withfthe end R 'of lthe portion Khabove'therail'base D, and the vsurface G oftlieanticreeper E.'

""It Vwill :readily be seen that'. .in this final 4operative `position the antiereeper `E firmly grips the raily A, the portion-'I being wedged lin to the fishing space betwet'eii the head Cv and'lbase D ofthe rail and pressing firmly against itV atk oneI side,l while the portion -K .presses firmly against they edge of c theV rail base D attlie other sidev of thefrailgfand that it is' efi'ectually llocked upon thefrail by *the position of theportionIv of the anticreeper E andtheengagement Yof its .surfaces F and G .with the` head Candbase D of the rail A. i

A :The direction in`4 which they rail tends to creepv isindicated by the arrow in Figure .2.

portion-V of the portion I and driving the wedge longitudinally rofthe rail to force the surface F outwardly from the rail and outof engagement with the rail hea-d C. Theanticreeper E 'will' thus be caused to move angularly in a plane Vtransverse to the rail'with the surface II of the portion I( riding upward on the rail base edge until the position shown in Figure 4 is reached, after which,lwiththe rail base D loosely embraced :by the antiereeper E, it maybe inclined fromthevertical and'move transversely ofk therail outofcontact therewith.

This inventionin its broadest aspect,re lating to the ytype of anticreeper herein disclosed that locks on the rail' by vengagement withthe head and baseV aty one side of the rail andthefedge of the .base of vthe rail :it

its other side isnot claimed'hereim but will befound'claimed in my cti-'pending applica- Y tion, Serial No. 722,317, filed June 25, 1924.
