UNITED STATES HARVEY M. GILLESPIE, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE P -& M

RAIL-ANCHOR.

To all whom it may concern: t

Be it known that I, HAnvnY M. GiLLnsrir., a citizen of the United States, residing at Webster avenue, Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

My invention relates vto devices for preventing the longitudinal creep of railroad rails, and has as its primary object to provide an improved device of this character which will grip with equal tenacity rails, the basefianges of which differ in width or thickness.

In certain types of rail-anchors spring action is relied upon to maintain a firm hold of the device on the rail. These devices, while being practical in connection with perfectly formed rails, are not well adapted for. use in connection with imperfectly formed rails, that is, rails which differ somewhat in the thickness or width of their base flanges. In devices relying upon spring action to maintain the necessary grip of the device on the rail to resist the creeping action, any/deviation from the standard con tour involving a narrowing or thinning of the base flange, results necessarily in lessening the effective grip of the device on the red. It has been proposed to overcome this objection by providing means whereby the torsional strain on the spring element may be increased or diminished to adapt the device to rail bases of difi'erent contours; In devices, such as last mentioned, any increase in the width of the rail base, such as results from the wearing away of the rolls em-' ployed in the/manufacture of rails, makes these devices unsuitable for application to rails of .this kind. My invention provides a rail anchor-which may be readily applied to perfectly formed rails pf different standards, to rails .wl1ieh, due"to ccrrosion or other causes, have base ilanges 'of lessdimensions than the prescribed standard, or to rails, the base flanges of which are somewhat wider or thicker than the prescribed standards, due, for example, to the wearing away of the rolls employed in their manufacture.

It is one of the objects of my invention to provide an improved device, of the spring type, which, under each of the above conditions,-will take a biting hold on the vertical edge of the base flange of the rail and also COMPANY, OF

grip with equal tenacity the upper and lower surfaces of the base flange of such rails.

A'further 'objcct of the invention is to provide a rail anchor of the spring type in which the jaws of the device will take. a wedging grip on the base flanges of rails of different sizes and contour.

In the drawings I have illustrated my invention in connection with the form of rail anchor patented to D. F. and D. L. Vaughan in United States Letters Patent No. 1,021,387, issued March 26, 1912, though it will be obvious that the principles disclosed might be eniobdied in other construct-ions.

The invention is illustrated in the accompanying drawings, wherein like characters of reference designate like jparts, and when:- in

Referring to Figs. 1 to inclusive, of the drawings, 10 designates a railroad rail and 11 one. of the cross ties on which the rail is; supported. The rail anchor is illustrated in its operative position on the base flange of the rail 10 and consists of 2 shoe 12 .formed to providea jaw. 18 which fits over one edge of the base flange of the rail in a manner to wedgingly grip the upper and lower surfaces thereof, end a spring elementgvjiich extends around the shoe member engages she opposite edge of the rail base The shoe is preferably made of malleebleiroii, or other suitable material, and provided with a foot or tie-abutting member 14: which against one of the vertical faces of the tie 11 The spring element above referred to designmed in the drawings by the reference Chamois!" anti eonsisis of a spring but having heel: o? 16 one end which is adapted to it over theeclge of ihe base flange of ills rail opposite file shoe member 12. upper portion 1? of the is preferably heat so to have an angular relation with respect is the body p01- lllOfl of the be? 15.
