The invent-ion "relates'to '1'211 anti-creepers. More particularly'the invention relates to spring clamp anti-creepers that are adapted to be strainedon installation tothereby establish a lever'grip on the rail thatis increased and utilized to prevent. the creeping of the rail by the pressure of the anchor against-the substructure whereon the rail, is mounted.

The invention seeks to provide an improved rail anchor of this type which is adapted to ,resistcreeping of the rail in 7 either direction. A further object ofthe in 'rai-l bearing plate of. ametal tie.

v 1n the drawings:

ventionj is to provide a simple and effective 'forni of rail anchor or anti-creeper which, ,t'orffunction'aloperat on, is adapted tobe seated-i-n a recess in a tie plate or in the fobject is to," provide an anti creeper having double or multiple lever gripfthat is utilized to resist creeping of the rail in either direction. The invention consists in the features of improvement hereinafter set forth, I illustrated in the preferred form in the accompanying drawings and more particularlyvv pointed out inthe appended vclaims.

As shown in the .draWing'sQthe improved" anti-creeper is more i particularly designed for use in connection with atie plate T interposed between the'rail Rand tie, T. The tie .platec may be ofany usual orsuitableconstruction and, as usual, is provided. with openings for receivingspikes Shy which the railand tie plate are secured'to the tie, The, tie plate is also provided, as usual, with -a shoulder S? for engagingone edge of the l anchors or A further rail base andfbeneath] the 0 5p 5sa e gefl the railloase it is provided with a rectangiu V lar opening,orholetfor receiving thelower portion of the anchor, 0rant1-creepercl1p Preferably also; the tie plate is provided with an upti' rnedprojection or hook K athi ch: bears upon and holds the anti-creeper clip against lateral displacement andwhich hookis held in contactwith the antisc'reeper by the shoulder S on'the opposite side of the-plateandv which, as stated, engages the opposite rail base flange. NVith, the rail well spiked down tothe plate andtie, the hook k K-coujld be omitted and the outer edge of the structure,couldbe l'arovidedwith a. similar properly vlocated and f proportioned hole or recess for receiving the lower portion of the anti-creeper clipy' thereby holding it in posi- 13-1 .Qnithe rail -base and also affording abutments QIL QPPOSltG sides of the clip against one or the other ozt which the clip takes a bearing finfunctional operation;

creeper clip made l in the shape of two In the preferred-form shown the antiflange embracing jaws A. and B"that are integrally connectQd through their top imern hers by a bar or plate L? '5 the latter, in ,the manufactured shape ofuiegcup prior to installation being' curved. upwardly so as to draw the bottommembers of the jaws toward each other making a "continuous rai1-' receiving space through the jaws less than the thickness of the rail flange asindicated by theidotted outline in Fi g. 5. The top and bottom members of each} jaw considered r by itselfljarespaced apart to permit itbeingmOunted without material internal strain on t-he'thickest flange with which the device is designed i-to be fused. Because of this large rail-seating space or clearance through each aw, the. connect on between the meniv berslot' each jaw can :be Landiis made as 1 rigid and-unyleld ng as poss ble so that,'. 1n

7 functional operation, the reaction force can be transmitted through the connection beti'veen thej aw members with a minimumof distortion of the *j aw itself. On the other hand; the connection betwe'en the jaws is made as yielding and re'silientTas possibleto'j permitthe mounting ofthe clip uponthe rail.

At installation, the resilient bar or plate L is so flattened or strained as to rotate the jaws in opposite directions away from each other and bring the flange-receiving spaces of the two jaws more nearly in line, thereby permitting the ready mounting of the device in operative position, as shown'in Figs. 3 and i. The recoil of the plate oribar L" 7 tends to rotate the jaws back to their initial relation (shown in Fig. 5) and thereby es-' tablishes a double lever grip on the rail base,

.jaw' A and its bearings a and a pr viding a. lever grip'in one direction and jaw Band its bearings Z2 and of providing a lever grip in the other direction, the full lever grip thus established and maintained being utilized in functional operation as hereinafter set forth. I

In the manufactured shape of the anticreeper shown in Fig. 5, the flange-receiving spaces of the jaws are so relatively inclined that, as stated, the continuous rail-receiving space is less than the thickness of the rail flange. Hence, when the anti-creeper device is placed in engagement with the rail flange,-

, sarily made-before that of the plate. It is noted that since the flange space of each jaw is made large enough for the thickest flange of any rail on which it is to be used, this space will be larger than required by the flan e of normal thickness as lndicated in Fig. l, and, the jaws A and B would be loose on the flange but for the strain developed in the connecting bar L which tends to rotate them back to their manufactured re lation. The grip of the device on the rail, therefore, is necessarily, as stated, that of a lever grip with bearings a and a paired n jaw A and bearings b and 7J paired 1n jaw B. I

In functional operation, if the rail tends to .move towards the left, as viewedin Fig. 4;, a the lower member of aw A comes in con-r tact with the side of the hole in the plate, so

that the tie reaction force is delivered to it by the plate T in'the direction indicated by the arrow 25, and tends to rotate this jaw counter-clockwise and so increasefthe bite or pressure upon the rail flange of the bearings a and a which serve as fulcrums of a lever grip. NVhen the reaction force is great enough to cause these hearings of jaw A to move or bite still deeper into the rust and scale, it will be transmitted to the jaw 13 through the bar or member L in the direction indicated by the arrow 27 and tend to rotate that jaw in the opposite direction, or clockwise, a tendency which it already has because of the internal straininthe longitudinal member L, and thus utilizing a second lever grip in a vertical plane with bearings b and 5 serving asfulcrums. A double lever grip. operating in a vertical plane on one base flange is thus provided and the reaction force distributed and delivered to the rail through four eifective'bearings. It is noted that the tendency in functional operation is to restore the clip to its manufactured shape and the principal strains of in stall-ation are relieved rather than increased. The result is that up to the point where the i'i'ialuifactured shape may be fullyrestored, the internal strains of installationwill take up and hold the bite of the bearings.

It is to be especially noted that if the rail 10 is to move toward the rightbringing the bottom member of jaw B in contact'with the edge of the hole in the plate on that side, the tie reaction force will be delivered to it in the direction indicated by the arrow 28. For vmovement in this direction, a double lever grip is eventually utilized with the grip of the jaw BcOming into effect first. The anchor is thus operative in either direction, it being noted that the reaction force in either direction tends to rotate the jaws in opposite direction, but each jaw in'the same direction and also the same direction in which the reaction ofthe resilient plate 'or bar L tends to rotate each jawL I The primary reason that the device is effective against creeping in either direction is found in the fact that meansare provided for the cramped or canted position of each aw providing an effective lever grip which is not reversed with a reversal in the movement of the rail, but, on the contrary, as,

stated, the reaction force upon the creeping of the rail in either direction tends to rotate or cant the aw in the same direction and increase the lever grip thereof which is initially established by the straining of the plate or. bar L upon the installation of the device. Since each aw is'thus effeotive'upon the creeping of the rail in opposite directions, one 1 aw alone will properly act to prevent creeplng of the rail in either direction,

even though the other aw, may not properly grip the rail base flange. f I

The improved anchor is of simple form and can be readily made of a resilient metal such as spring'steel. The-top and bottom members of the jaws A and B are preferably made relatively short compared with the width of the rail base, asshown. As

already specified, the connections between the top and bottom members of the jaws which extend around the edge of the rail base flange are made a's'heavy and unyield- 1I1g as possible so that the strain of instal-" lation will beeftectively stored in the more resilient connection L between the jaws.

The inproveinent provides a spring- 'clanip' anti-creeper that will establish and m intaina lever grip upon the rail base; and, in the preferred form, a multiple lever grip upon one rail base flange which is utilized in functional operation to resist the creeping of the rail in either direction. Itfur ther provides a siiiiple and inexpensive forin ofanti creeperwith a non-reversible lever grip on one rail base flange adapted to c0- operate with the sides of an opening in a tie plate or other like part of the sub--struc ture to effectively resist the creeping of the rail in opposite directions.-

The attention is ealled to the fact that the terni jaw throughout the specification and claims has been usedto designate an element having opposite integrally connected members adapted to embrace the rail base,

'or in the preferred form shown, oneofthe.
