- To all whom it' may concern Be it known that I, PHILIP W. Moons, a

4,citizen of the United States, residing at Evanston, in the county of Coolr and State of Illinois, have invented certain new and useful Improvements in aibAnchors, of

which the following is a specification.

My invention rela-tes to devices' for the purpose of preventing 'the longitudinal movement or creeping of railroad rails, and to an anti-creeping device or rail anchor of the general type of the anchor patented to D. l?. and D. L. .Vaughan in- United States Letters Patent No. 1,021,387, issued March 26, 1912, .in which' spring action is relied upon to maintaina `firm hold of the device on the rail. i

The principal object of this invention is to provide an anchor, of the `spring type, which will p the'base anges of which diifer somewhat in size or contour. Rails even of the same weight and made presumably in conformity with the same standard will be found not infrequently to diii'er to va certain extent, in their base iange dimensions due, for eXample, to incorrect' rolling, or it may be to oorrosion of the base of the rail after the rail has been subjected to theweather for some time. In an anchor of .the spring type any .deviation from the standard contour involving a narrowing or thinning of the base lianges results necessarily in lessening the e'ectivey grip of the device on the rail provided lthere is no provisionin the anchor itself for' adapting 1t to rail bases of the lesser dimensions. My invention provides a rail anchor ,so constructed asto permit an initial adjustment or application ofthe device to a rail which may be made in accordance with the size and any ordinary variation from the standard this invention,

and construction of its parts, the rail anchor above referred to,A it wni be contour doesy not impair the effectiveness of the device in the function.

While I have shown a rail anchorwhich, except for the improvements constituting closely resembles, in the form performance of its intended Specilcation of Letters Patent.

n the drawings the rail is indicated'at 10 and the tic at 11. The arrow (Fig. l) indicates the creeping tendency which the `anchor is designed to check.

The anchor consists of "a shoe or rigid member 12, which is preferably a malleable casting, and a spring bar 13 preferably rnade of steel. The casting 12 is formed to provide a jaw 14 which engages one edge of the base flange 15 of the rail, and a foot or tie abutting plate 16 adapted to bear'against Fig. 6 isY a.`view,

` the side face of tie 11.

The spring member 13 is formed with a'` hook or jaw 1'( adapted to engage the base iiange of the rail at a point opposite shoe 12, the upper portion of the jaw being bent so as to providea diagonally disposed lip 18 which' bears upon the upper surface; of. the rail basel The other' end of the spring member 13 is formed with an enlargement 19.

The portion of the spring member extending under the base o1 the rail is preferably, though not necessarily, given a slight twist so the normal position p 19 will be oblique to the plane of the Jaw 17. The shoe is formedwith a recess 20 adapted to receive Vthe enlargement ,19 on the spring member.

stepped seats
