RAIL ANCHOR MEANS Filed Dec. 16, 1946 INVENTOR. W 5/104 Patented Mar. 28, 1950 UNITED STATES PATENT OFFICE RAIL ANCHOR. MEANS Tom W. Saul, Tucson, Ariz.

Application December: 16, 1946, Serial No 716 508 7'Claims.

My invention relates. to means commonly referred to as antiecreepers. for anchoring, rails to ties, or the like.

One of the; principal, objects. of this invention isto: provide a rail anchor. or antiacreeper of this class whichisof. V-shape. and which may be secured in. place over abase flange of. a railroad rail-,by forcing-the. sameover the outer. edge of the flange, and. thereby-separating the; jaws or legs. of the V-shaped anchor. so. as. tov embrace. tightly, and over their length, the opposite faces of the flange-l An important objectalso is to provide an an.- chor. of. this class. having. a: stop; which provides a definite limit meansso as to prevent spreading of the. jaws. or legs of. the anchor, beyond its. most efiective gripping action, upon the. opposite sides of. the flange,

Another important objectof this invention. is to provide simple andeconomica-l means. for creating effective friction betweenthe. adjacentsun faces of the railflange. and the anchor or anticreeper when the latter is driven or forced. over the former:

Another important object. of this; invention is to;- provide. means between the engaging or contacting. surfaces, or portions of the rail flange. and. anchor, to. increase. the. gripping action. of the anchor uponthe flange, bybiting into. the; adjacent faces or. portions of. each, such means being in, the form of ahard, sharp, granular ma.- terial. interposed between. the. adjacent surfaces. of. the rail flange andanchor.

A furtherimportant object. of this inventionis. to providea yieldablebinder for locating the granular materialin. the desired. manner between such surfaces,

A; still further .importantobject is. the provision. of. a yieldable; frictional material, which will .assist. in thegripping action ofthe jaws-or legs. upon the. opposite sides: 01'. faces. otthe base flange...

Another importantobject ofthis invention is to. provide an. anchor of this class which is particularly simple and economical of construction, and which may be easily applied, and one which may be removed without much effort, and also one which may be reapplied or reused.

With these and other objects in view, as will appear hereinafter, I have devised av rail. anchor means having certain novel features of construction, combination, and arrangement-of parts and portions, as will be hereinafter described in de.- tail: and particularly set forth in; the appended claims, reference being had to the accompanying drawings and to the characters; of reference thereon, which form apart othis1app1ication-,.in

which:

Fig... isiatperspective. view of: a portion. of. a railroad rail with my anchor in its preferred form mounted thereon;

Fig. 2 is an enlarged elevational view of myanchor, partly in. section, shown mounted. on a fragmentary portion of a base flange. of the: rail, the flange being also shown in section; and,

Fig. 3 is a fragmentary view of my anchor, part.- ly in section, ina slightly modified form.

The rail I, shownin thedrawings, is of a. crosssection commonly employed in railroad rails. The portions I designate. the base flanges which. ex.- tend laterally. from the rail, and supportthe same on the railroad tie. 2. The purpose of my rail anchorv means A is. similar to. that of other anchors of this type now in: use, and. is mounted on one of the baseflanges. of therail. in such a. manner.v as to abut one side of the tie to prevent. creeping. of the. rail thereon.

The. rail. anchor means A. comprises, essentially an. anchor member, which is substantially V- shaped,v and comprises. substantially straight legs. II and I2 connected at one end. by. a connecting portion I3, thelconnecting portion is substantially circular and of. approximately 220. degrees or A3 of. a. circle, in extent. The endsof the. connecting portion. L3. merge. ingradual reverse. curves. with the legs II and I2.

The legsand connecting portion of the, anchor member. areof. uniform thickness. and may therefore be. forged. from bar. stock.

I he legs II and t2 diverge from the connecting portion [3. at. anv angle slightly lessv thanv the. included angle between the upper and lower faces of the flange l Thus, when the anchor is driven over the outer edgeof the flange, the legs, which formv jaws, spread. apart, so that. they lie substantially parallel. to. the adjacent. faces of the.

' flange, and, as they are bent. outwardly, they ex.-

ert a clamping or gripping. force upon the ad.- iacent portions. or. faces. of the. flange. For this reason the. anchor member is made. slightly re.- silient to permit the legs or jaws to be spread and tightlyto. grip thev flange.

The anchor. member isso shaped that itmay be forced over the; edge of. the rail flange to arr extent onlywhich prevents the spreading of. the.

. legs. or jaws:v beyond its. most effective gripping action. upon the opposite sides or faces of the.- fla-nge. Such limiting is effected by the engage-- ment of. a portionnear the center ofJthe-connect.-- ing: portion I3. with. aportion of the. outer edge of the flange, as; indicated: by I3 in the drawings;

This limiting. portion may be; in the form of. a. segment I4; at. the innerside of the connecting; portion I3", which may' engage the outer" edge of. the flange; I to effect; a. more positive stop: This; stop or limiting segment:- M'may be. separately fabricated and secured to the. inner side. ofthe: connecting portion, indicated: by dash lines, or the connecting portion may be upsetto this errtent to provide such stop or limit means.

To facilitate the gripping action between the adjacent faces of the legs or jaws and the faces of the flange l I have interposed a hard and sharp granular material l5 therebetween. This material may be of various forms, such as Carborundum. This material may be more effectively placed between the engaging portions of the rail and anchor by affixing it to the inner sides of the legs or jaws by means of a suitable cement 16. This cement is preferably pliant and resilient.

As the anchor is forced or driven over the edge of the rail flange by means of a hammer, or the like, the hard and sharp granules are imbedded or bite into the metal of both the rail and the anchor and substantially or temporarily lock the anchor in position.

The cementitious material [6, which performs the function of evenly distributing or locating the granules l5, also assists in providing a frictional joint between the rail flange and the anchor, at the portions between the granules l 5.

In Fig. 3 I have shown a modified form of the means for creating or producing friction between the adjacent faces of the anchor, designated here as 2!, and the flange l Such means is here shown as a shim 22 which, when in position, is of U or V-shape. When the rail and anchor are made of steel, as in conventional construction, the shim is made of friction creatin material, such as cast iron.

In this modification the outer end of the anchor is also of slightly different shape, which permits the whole anchor to be of uniform thickness. This form may also be used in the first described structure.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

I claim:
