JESSED. GRIMM, OF WATEBSVILLE, MARYLAND.

'nn'rronn'nrnn non RAILROAD RAILS.

Application filed August 23, 1922. Serial No. 583,808.

To all evhom it may concern: I

Be lt known that 1, Jesse. D. Gianna, a

citizen of the United States, residing at' VV atersville, in the county of Carroll and State of Maryland, have invented certain new and useful Improvements in Anticreep ers for Railroad Rails, of which the following 1s a specification, reference being had to the accompanying"drawings vide a device of this character capable of being applied to any railvwithout requiring alteration of the rail, or without rcqulring fastening means for connecting the device to the rail or he.

Another object of the invention is to provide a device of this character including' jaw members adapted to engage a'rail,

and yieldably urged toward the rail in one direction, and means engaged with the jaws -for urging the jaws in "the opposite direction intoengagement with the rail upon creeping movement of the rail. 25v

It is'a further object of the invention to provide a device of this character including a pair of movably connected jaws, said jaws being provided with means for oscillating .the same'upon creeping movement of the rail. I U i With these and other objects in view, the invention consists in the improved construction and'arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated'in the accompany ingrdrawings, in which j igure 1 is a side elevation of an anticreeper for railroad rails constructed-in ac- :the rail; i

cordance with an embodiment of the invention, the anti-creeper being applied to The face 12 is' also inclined relative to This invention relates to anti-creepers for railroad rails, and has for. its object to proin the same plane. stops 13 and 18 limit pivotal movement of beyondthe side faces of the shank, said projecting portions having its the shank and disposed substantially parallel to the inner wall 11. The opposite end portion of the enlargement, or that portion projecting from the opposite side of the shank, is canted as at 13 in the opposite direction to the inclination of the face 12 and inner wall 11 of the sh'ankt'o provide a stop, said stop terminating substantially at the central portion of the shank. The end portion latof' the shank is canted, the canted portion li being disposed in paral- 'lel' relation to the canted portion 13 of" the stop. An opening 15 is provided in the shank 8 adjacent the canted end portion' 14. I

The jaw member 7 includes a shank 16 having an enlarged extension 17 projecting from the end portion of one face of the shank, said enlarged portion havingits end face 18 canted to provide a stop similar to the end face 18, but cantedin the opposite direction to that of the canted face of the stop 13. The extension 17 isalso reduced and undercut as at 19 to form the jaw, the inner wall 20 of the jaw being canted with respect to the shank and injthe opposite direction to the canted face 181 The inner wall is serrated co-penetrate the rail.

The end face 21 of the jaw is likewise canted and disposed in parallel relation to the end wall 20. j The end portion 22 ofthe shank is canted, said cantedportionbeing disposed in parallel relation to the canted portion18. Said. end portion of the shank 18 is provided with an opening 22*, the purpose'of which will be hereinafter described.

The shanks of the jaw members 6 and 7 are intended to be disposed one upon the other, the under face of the shank 6 engaging the upper face of the shank 7. By the provision of the enlarged portions forming the stops, the outer faceof one jaw memher is permitted to lie flush with the outer face of the adjacent jaw member, thereby positioning the jaw members substantially At the same time, the

the jaws;

When the jaw members are assembled the "canted end face of one jaw member is disposed substantially parallel with the long1-.

'tudinal edge of the shank of the adjacent jaw member. Thus the jaw members are disposed substantially in parallel relation to each other regardless of the angular re lation between theshanks oi' the jaws s0 as to permit the jaw members to engage the rails at all points longitudinally oi? the aws.

In connection with the aws, an oper ating member 23 is provided, said operating member being longer than the shanks of the j aw members and having its end portion 2% beveled from the central portion to the end :tace oi the operatingamember so as to prevent projections at the connection or the members to each other. The opposite end portion of the operating member is provided with a :ioot 25 which extends in a direction opposite to that oi. the jaws and is intended openings provided in the shanks of the aw members 6 and 7. A pivot pin 27 is passed through said openings to movably connect the operating member and jaw members to each other.

Each of the side faces of the shanks of the jaw members adjacent the operating member is provided with an eye 28, to which one end of a spring 29 is connected. This spring is normallyintended to urge the aw members substantially toward each other and into binding engagement with the rail.

In operation, the jaw members are moved away from each other to permit the insertion of rail A tl'ierebetween, the serrated inner walls 11 and 20 oi the jaws engaging the edges of the rails. The jaw members are then moved along the rail until the foot 25 comes in contactwith one of the railwayties. Upon release of the jaws by the operator the spring 29will urge the jaws into binding engagement with the rail. It will be noted that while the jaw members are disposed at anin clination to each other and the operating-member, that in view of the inclination of the serrated inner walls 11 and 20, said walls are disposed parallel to the edgeof therail, so that yieldable movement of the spring will cause binding engagement of the aws on the ra-ils. Should the rail start to creep, the movement of the rail will urgethe foot to firmly engage the tie, andcause pivotal movement of the shanks 8 and 18 relative to each other. Thismovement permits the spring 29 to urge the aws into firm engagement with the edges of the rail.

During pivotal movement of the aw 1116111. iers .on the operating member the spring contracts, thereby urging the jaws into binding engagement with the rail through the cooperation of the operating memberi23, as the operating member is substantially urging the pivoted .ends of the shanks of the jaws away fron'i the spring, whichnaturally per- -i n1ts the spr1ng to pull the outer ends of the aw members inwardly so that a double clamping operation is provided which causes without rigidly attaching the device to the tie or the rail, other than the means provided by the serrated inner walls of the jaws, and all of t ese features are posse-ssedby a device which is composed of only three parts.

These, in view of their simplicity and sub stantial qualities, will operate under all'con ditions and will last indefinitely.

What is claimed is z 1. An anti-creeper "for railway rails comprising jaw members movably connected to each 0ther,'means for normally urging-the jaw members toward each other, and an actuating member movably connected to the jaw members at the pivotal connection of said jaw members to eachot-her.

2. An anti-creeper for railway rails comprising jaw members pivoted at one of their ends to each other, a spring connected at its ends to said jaw members and normally urging the jaw members toward each other in one direction, and an actuating lever pivoted to said jaw members at the pivotal connection of said jaw members to each other to permit the spring to urge the j awsinto binding engagement with the rail.

3. An anti-creeper for railway rails comprising a pair of jaw members, each jaw member including a shank, the end portions of said shanks being disposed one upon the ther, said end portions having registering openings, an actuating member having an opening in one end thereof adapted to register with said opening, a pivot pin connecting the shanks of the jaws to each other and to the actuating member, a foot carried by the opposite end of the actuating member for engagement with, a railway tie, said actuating member causing movement of the shanks of the jaws upon movement of the rail.

4. An anti-creeper for railway railscomprising a pair of jaw members, each jawiiiember including a shank, the outer trace of one end portion oi one shank and the mner face of one end portion of the remainlng shank being cutaway, said cut-away portion members being serrated, and canted re-- spect to the shanks, an actuating member having one end thereof engaged with said ends of the shanks, a pivot pin extending through said shanks and the actuating member, a spring connecting the shanks of the jaw members to each other andnormally urging the rail engaging faces of: the jaw members toward each other, said actuating member having a foot on one end adapted to engage In testimony whereof I hereunto aflix my signature.
