To 'all' whom 11i-may concern;

Be it known .that I, vFREDERICK PRES- f'roN, e citizen .of the United States, residing at Highland Park, in the county of Lake and State of Illinois, have invented new and useful improvements in nticreepers, of which the following is e -full, clear, concise, and exact description, reference beingl had .to the accompanying drawing, forming o part `ofthisv 'specificati-on.'

My invention reletes to' anti-Creepers for railroad rails, such devices being known also as rail anchors.

maintains its hold by reason 'of of jevvs which grip the rail bese with e firm frictionel'holfi', the constrnction' is nsinilly `such that when the rail tends to creep', said jews `ere lnovetlL inwardly toward the'longitudinal axis ofthe/rail so as t6 increase their frictional hold. To secure this action such rail anchors have been constructed, generally speaking, in two forms. In one 'orin there are' tvs-.0 or more parts which engage each other in such e manner that when they slide one on the other longitudinally, the pairs of jan-s are moved inwardly to grip the rail hase more firmly. In the other form the rail enchor'coniprises 'e one piece yolre having jaws spaced apart e distance greater than the lWidth of the reilbese whereby the rail anchor may be located on' the rail base proporly, but in orderv to cu'se both pairs ofseici jaws to grip said rail base, it is necessary to vskew the rail anchor to a. diagonal position,

that is, with the jaws arranged one 'pe-ir considerably in advance of the other. in this position, although said pairs of jews are not brought closer together, they are each brought closer to the central axis of the reil.

The object of my present invention, genorally speaking, is to provide a rail enchor which maintains its hold on the rail bese h v friction due to its initial grip thereon, there being iio' subsequent movement which in'- cregises or tends to. increase seid grip.

VThe subsidiary 'objects are to provide a one piece rail anchor adapted to act in this manner, to provie e rail anchor of this character Which shell be of comparatively simple construction and len-ti itself to econoni'iccl manufacture, and to provie a. rail enchor Which-shall eiiectively maintain its Specification of Letters Patent.

Other objects and solvente es may' he readily inferred. without speci c .reference thereto,-froni 'et consideration of the deteiliecl description hereinafter' fornisof the invention.

In the accompanying drawings i hev'je illustrated the several orrhs 'referreclto. The iiiw'rentioii is not limited to the construe# tions illustrated, however, es it may be enib'o'ciie'cl in other forms.

In seid drawings Figure i is a top plan ci one' forni of rilenchor, showing the seine es it is being applied to the ril base; Fig. 2 is en .end elevation thereof; Fig. 3 is a top plan View of sa'ici rail aiich'o'r'in' the position which it finally assumes upon the rail bese; Fig. 4 is iin end elevation thereof; F 5 is e vside elevation or' this orni'of enti-Creeper; Fig. 6 is a traterl comprises a pair of jaws 1,2, each etla'pteii to grip the reil base firmly when vforced thereon, said pairs 'of jews b ing proviol'ed with a connectingvniemher' which is preferehlyintegrel therewith whereby e one piece construction results. ln Figs. l to "2' inclusive, the connecting member has the form of e yoke 3 arranged at one end of saisi jews, lthough it may be otherwise loceteil with respect thereto. Said yoke has e bearing face adapted to hear against the cross tie 5, thus transmittingtherctothe ndtie to 'the creeping tendency of the rail. Seid yojlre is also provided preferably with a reinforcing iange or Web 6 integrally united thereto.

The pairs of 'aws i enel are arrensje initially with their inner vertical walls 8 flaring outwardly, es shown in Fig. l, for example. The distance between the inner edges of said pairs is preferably somewhat vless than the Widthv of the rail hase.

Inorderto cause's'aid jaws to take a rin hold 011' the rail'. base, theyjare driven toward'eachother by hammer' blows. Vuntil' they assume' .the *position shown in' Fig's 3 andA.v This operation, of.

course, causes the structureztobend o r give Lat some'point, mostof thebending taking placaat or near v the oppositeends .ofthe yokefa*y `The rail-anchor being constructed. preferably of malleable iron or .other mate- -rial"1having six'nilanA properties las far' v"as bending is.- concerned, this deformation of V- vpreferably of a'f somewhat less 'angle'inii tially than the corresponding angle made by 'the-upper and lowerffaceor` the rail base.

Furthermore, the vertical innerwalls 7 and 8 oflsaid'jaws are preferably of slightly less height than the correspondingvertical outer edge' I.ofl the .rail base.' Accordingly, when the'jaws are, driven or 'forced onto-the rail.v I

The design at the pressure or gripis preferably li th ping action o jaw is substantially u niform at all points.- That is to say, the jaw is' spnungthe-'most" at pointsfremote from the vertical wall 8, at which'pointsfthe lever vI arm is. the longest, and is. sprung f the "least at points where the lever arm is shorter,

- thereby tendingfto give substantially uni- -formmoments. 'As the railtendsto base has a bind-iri'gv eii'ect thereon, this-action f offered to the creeping thrust. The area of '.the jaws in frictional engagement withthe f yrail base is of considerable.' extent, due
