" The invention Vrelateslto* anchors. for Jpre# venting rails froml creeping;

them against creeping.

' Another object'ofv heinvention is to pro-'` vide an' anchor of this type, which is simple in construction, whichmay be produced at a low cost, and in which the vstresses are distributed so'that the practical minimum of metal in the body of the anchor need not be excessive in weight. e The inventionfconsists in theseveral novelk features hereinafter set-forthand more-particularly defined by the claims atfthe conclusion hereof.

In. the drawing Fig.l l 'is `an 'end-'elevation of an anchor embodying the invention and applied toa rail; Fig. 2 4is avertical section taken on line 2-2vof Fig. 1. Fig. 3 is a plan, Fig. 4 is a section taken on line 'll- 4: of F ig.V 3.: Fig. 5is a section takenon'lin'e V5-.-5 of- Fig.4.

The invention is exemplified in albody A i i formed of a single casting and with ajaw at one side thereof to extend around the base- '30 flange at one side -of theirail and aspring washer Cheld in the body and applied torsec'ure the .bodyon the rail. This lafw is formed of a lowerwalla to engage the underside'of the base-'flange b on one sidev of the railB and an upper/wall a* unite-d to wall a by a side-wall a5.; and vertical reinforcing webs a andjo united to the ends ofthe web a and extendedabove and .below thefjaw. A downward extension ra'of wall a forms an oabutmentor stop to engage atie on which,k

lthe rail is laid. A laterally 'extending arm I a@ projects transversely fromY the wall a under the rail and isjprovidedwith a hook ja? toengage thevbase-flange b on the opposite side of the rail'. ,A connecting rib atbetweenwalls a and a2 and a rib ala between extension a? and Wall a are integrally `formed with the body A.1 y'An approximately circular pocket as for the washer' C is formed in the upper wall .50 a* ofthe jawl on the bod-y, a portion of which 1929.

yoverlies the outer portion of the flange bland l e the remainder of which is disposed laterally The robject `ofthe invention isfto provide n a rail,` anchor whichfcan'be .readily applied 5 to rails and which will be effective in holding.

. prises continguous ends c, c whichare relatively olfset and disposed at the inner sid'e of the jaw at the `o pening a9. The end c f .forms a downwardly pressed terminal or tooth for engaging the top'of the flange b and k60 y the end c bears against the top of the pocket sothat end c will be-forced against flan e b. The outer. portion of the washer is -coV ned in the outer. portion vof the pocket While the end 0 is disposed in the portion of the pocket 65 a? whichhas nol bottomso that end c can engage the flange'b. i A rib al is 4formed in the top of the pocket a8 soy that the washer will be liheldagainst radial contraction inthe pocket; j A notch all is formed inthe topof the pocket to receive the end e of the washer Y to lock the latter against rotative movement in the pocket. The washer maybe formed of chrome steelfand is adapted to withstand a high compression, for example, v16,00() 75 pounds. Whilepartially compressed, it is inserted transversely Vinto the pocket as through the inner open side of the jaw so the washer will be held in thepocket under, and by its own, spring pressure when it has been inserted in the jaw. The retaining rib a10 slopes outwardly and upwardly to permit the washer to be inserted in place.kk A depression alz is formed in the wall a and arm a to'facilitate forcingV of the flange b under the 85 washer. In Yapplying the'anchor to a rail, itsfjaw is first placed in -position indicated by dotted lines in Fig. 1the end 0 ofthe washer en- 'g'agingthe top ofthe flange b and-frictionally- 90 f olding the anchor; Blows are imparted vto yan anvil 115 formed onthe outer side of vthe jaw to drive the` anchor transversely into tom of the rail through the pressure of the 1W of flange band be compressed siiiiiciently to the reverse` direction. This permits theanf,` chor tolbe driven longitudinally of the rail sa washer against flange b. When the hook a? hasxclearedthe outer edge of flange b', the anchor will be tapped transversely in reverse direction until the hook a7, interlocks with the margin of flange b.

As the jaw is forced into this position, the washer will ride onthe .upper inclinedsface cause the end c to exert a very heavypressure against the Viipper face of thefiange o and jam the wall against thebottom-fami of fiange b. The end c of the washer has an end `face 02 and is downwardly inclined as at c3 to act as a ratchet or` one-waytooth to bite into ange b, toV npermit the anchor to slipin onedirection and positively grip the y.

raijl to lock the Aanchor `againstmoveinent in toward the tieuiitil the abutment a3 is in close engagementtherewith. When the rail islstressed toV move toward the tie, the end cof the washeracts as a positively engaging gripping :tooth to lock the anchor to theraill and to render the anchor effective` to prevent v creeping of therailin one direction. Thus,

thiswasher serves tol effectively prevent relative movement in one direction by the rail and the anchor. Y

\ The invention 'exemplifies an anchorwliich consists of` an integral bodycontaining a spring Vwasher for `gripping the rail to lock,

\ suflicientpressure to prevent displacement of the hook 'a7 from the flange b.' The anchor can be easily driven on the rail,'and dispenses with adjustable wedges or devices and requires no drilling of the rail. The entire anchor consists of a single casting and the spring washer, so it can be'produced at a low cost. The spring washer has been found to exert vsufficient pressure to eiectively prevent the rail from creeping.

strieted tothe details set forth, sincethese may be modified within the scope of the ap-v pended claims, without departing from the spirit and scope ofthe invention.v v
