RAIL-ANCHOR.

Specification of Letters Patent. Patented F b 22 1916 Application filed July 26, 1915; Serial 41,809.

'1 '0 all'w/wm it"iiizy concern:

, Be it known that I, Axmieiv STARK, a citi- Zen of tliei'U'niteicl States, residing at Chicago, in the county of Cook and State of 4 Illinois,lia 'efiifvnte'd certain newand usefl'il Impievnien 'sin Rail-Anchors, of which the following is a specification, ref erencebeingl ifd to the accompanying drawforming iii-pm; thereof. 'lli"'piir ')oseiol this invention is to providea'devifce' 'fflthe class known as rail ai clior's'designed tobe attached to railway rails and-to abut'tlie cross tie for preventing longitudinal cree ji'n'g of the rails.

*ltconsists of the features and elements described and" shown in the drawings as indicatedby the claims. a In the'd rawings': Figure l is a top plan viewipartiallyinsection of a device embodying this invention, the outlines of the rail and cross tie being shown in dotted lines, Fig. 2 is a bottom plan view of the device shown iri 'liig 1. Fig. 3 is a top plan viei'va-of the-device-with the wedge member 25 're'm'ovedand with the gripping members positioned foi-reii'ioval from the rail. 'Fig. 4 is a sectiontaken longitudinally of the rail asindica'ted at line on Fig.- .1. F ig, 5 is a sectiont'aken transversely of the'r'ail as iiidiCated'at -Ii'ne on Fig. 1.

The device illustrated in'the drawings is a three-piece construction composed of ,two gripping members," A and B, respectively, andfia 'weHge i'neinber, C. The gripping member, A, is foiiiiied with hooks, A and A at its o p 'pos'iite ends respectively, extendingab'ove'its fiat f'surfaces, A and opening toward eachotherii The middle portion, A,

o'ff the uppersnrface of the member, A, is.

depressed below the plane of the portions, A A fa nd formed with a pivot stu'd or boss, Ai, toreceivethe middle portion of the member,- B, which is apertured for-the purpose at- B4. W'heii the parts, A and B, are'thi'is' assembled with the pivot, A engaging the apei-tiire,.B,the flat areas, B, of the ineiiibe'r, B,will he in-aboiit the same surfaces, A? and B into contact with the under surface of the'rail flange. The over hanging terminals of the hooks, A and B. are slanted off at A and B so as to be alined with each otherwl-ien the members, Aand B, are swung together about their pivot to their position of least, angular divergence.

A? and B is a maximum and is sufficient to permit the former 'pair of books to be engaged with one. edge of the rail flange while the latter pair are swung upward past the opposite edge of the flange to'bring the In this position the-distance bee tween the hooks, A? and B and the hooks,

B, now provides space for the insertion of the wedge, C. The areas, A and B3, of the gripping members are each partially bound ed by the curved outline of'the shoulders,

A" and B, which are positioned for contact with the diverging lateral edges, C,-o f

the wedge, C, as the'latter'is inserted in'the device. The curves'of these shoulders ..-are

so formed that all four of the shoulders'will' remain in contact with the straight-but di verging edges, C, "of the wedge, C, at the successive positions of the latter as it is driven farther and" farther into place,

though it will be evidentqthat such inward hooks, A andB or between the ho ok s,A

and .B, or even between both pairs ofilio'oks;

To permit this action theaperturepB-"eis made considerably largerf'than the pivot pivotal connection controls the moveme nt' and position ofithe gripping inei'nbers. It

will be evident; that thisimplies" that the curved vertical walls, Affand BX-of the;

hook portions constitute temporary and shiftii'igv fulcriims for the -'.an'gular move,

ments-jof the gripping members, A and Br as they adjust tliems'elves to successive posi- I respect to the edge but close upon the rail,

the hooks, A and B approaching each otheras they are pushed farther and farther from the hooks, B and A respectively.

The depth or thickness of the wedge member, C, in a.vertical direction is approximately the depthof the depression at, B, @in the grippin member, B, and may be substantially uni orm throughout the length of the wedge except that its tip, C may be tapered 'or beveled to a fairly thin edge to facilitate entering it. 'However, it is desirable that. as the gripping surfaces, A and B", on the'hooks approach their final position on the rail the inner or downwardly facing surfaces of the hook terminals may also come into strong frictional contact with the rail flange. To insurethis the lateral edges, C of the wedgemember, C, are slightly undercut or beveled so that the wedge is somewhat wider at its top surface than at its bottom, and the curved shoulders, A". and B, are correspondingly beveled to form sloping faces for the sides of the wedge, C, so that as it approaches its final position of maximum tightness the wedge tends to rise out of the groove into which it' is driven up against the under surfaceof the rail flange, thus causing the hook terminals on the gripping members, A and B, to react strongly upon the upper surface of the rail flange, and producing a final engagement of the device with the rail in which the rail flange is gripped bothverti- '35 cally and transversely and itself. frictionally engages not only the gripping members, A and B, but also the wedge, C, at its upper surface. The wedge may be made of rolled steel-or as a malleable casting, so that when it has been driven to this final position its tip or point, C, may be bent up around the edge of the rail flange so as to effectually prevent the Wedge from working loose.

Looking at the under side of the device, it will be seen that except at their lapped middle portions both of the gripping bars, A and B, are formed with vertically disposed stiffening ribs, A and B, respectively, which extend'up aror ad the hooked ends of the members for str ngthening these portions. One of these ribs on the bar, A, is enlarged into a considerable flange, A, de signed to abut the vertical surface of the cross tie directly ahead of the device to render the latter effective for its purpose, namely, preventing creeping of the rail. This flange is reinforced by a stiffening rib or brace, A. The wedge, C, is formed with a downwardly extending head portion, C", which presents a larger area for driving and which when the wed e is driven home to its final position alines oproxirnately with the bracing rib, A, so at'any stress against the flange, A, can by the tendency of the rail to creep lo" ;udinally is transmitted compressively through the brace, A, and

the head, C to the gripping member, B at B It snot expected that such stress will cause any relative movement among the moving over the tie.

It maybe noted that the nature of this device makes it possiblefor one size of gripping bars, A and B, to serve on any one of two or three sizes of rail simply by the provision of different. wedges, C, of various widths. \Vithin certain limits the gripping bars may be effectively engaged with the rail flange at various angles, and their range of angular movement for engagement or disengagement may be shifted to' different parts of their total range of movement simply by the use of such differing sizes of wedges, C. This coupled with the fact that the accommodation of the vertical wedging to the horizontal wedging action as above described renders all machining unnecessary, making it possible to'use simple casting for all parts, makes the device acomparatively inexpensive fixture.
