e,it ownt at I, RAY J BEnTHpUD, a citizen o the, United St tes, residing at S antbn in the county of, ulton and State poi t, have inventedcertain new and usef Impr vements in Anti-Rail-Creepers; I do eclare the following to be a full, clear, an exact descri tion, of the invention, suchaswill enable, otiiers skilled in the art to ,which itappcrtains to make and use the sa nareference being had to the accompanyingdrawings, and to the letters and figures of,refe e ce ,markedthereon, which form a part, of th isspecification,

A familiar diff culty encountered in railway 1 operation especially in double track roads in which the, traffic upon the respective tracks is but one direct1on,is the tendency of t e rails to overcome their fastenings to the ties and to creep longitudinally. Various devices have been proposed for overcoming thisdifiiculty, and some of the anti-creepers have, in a measure, prqvedsuceessful. Usually in these devices a slight longitudinal movement of the rail,

causes the anti-rail creeper to closely grip the foot of the rail and to prevent its further movement, but the rail must first move in order to cause an efiective grip upon its flange. Now, when the reaction from the blows of the passing car-wheels takes place, or when an opposite stress occurs from trains movin in the other direction, the hold of the gripping device is loosened and before it can again properly grip the rail the rail must move slightly beyond the gripping point at which it was held in the first instance. Thus the gripping device is constantly loosening its hold and is often taking a new hold at a point slightly in advance of its last preceding hold, so that while the creep of the rail is retarded it is not wholel prevented. To overcome the difliculty ahove indicated, some devices of this class are provided with means for positively anchoring the rail-gripping member to an adjacent cross-tie, thus adding to the guniiber of parts, weight and expense of the e ce.

My invention is desi ed to provide means the prevented exceptby a corresp ndingmoye nent of thecross-tie with w ic h the cl device is in contact.

A furtiigr object of, myinventionds to provide an anti-creeping device for rails which shag be light, simple, inexpensive and strong an which may becreadily applied and removed.

To these ends my invention consists of,the construction and arrangementof parts hereina fter described, and shown and illustrated in the accompanying drawings, in which Figure 1, 1s a top-plan .view otmy device, appliedtoa rail; Fig. 2, a like view of a modified form of the, same; Fig. 3, a per; spectiye viewcf the device shown, in Fig. 1, detached, and Fig. 4, a like, viewof the device shown in Fig. 2.

Like numerals of reference indicate like parts. throughout, the drawings,

n thedrgwings, 1 is across-tie and 2 a track-rail o the usual construction having an ordinary baseor flang.e 3..

4 is a plate disposed transversely of and resting against the under side of the base 3. One end of the plate has an upturned hook 5 which engages one margin of the base or flange 3. The opposite end of the plate 4 is provided with an upwardly projecting hook 6 which engages the opposite margin of the rail-base. The plate 4 has, projecting horizontally from about its middle, an elongated arm 7 disposed at an angle to the center line of the rail and having at its outer extremity an upturned hook or flange 8 adapted for engagement with one of the margins of the rail-base. The plate 4 has at its edge oppo site the arm 7 a downwardly turned flange or head 9 which when the device is in place rests firmly against that side of the cross-tie toward which the rail tends to creep as indicated by the arrows.

In the example of my device illustrated in Figs. 1 and 3, the hook 8 is, by means of a powerful lever sprung outwardly and upwardly into en agement with the margin of the rail-base. his slight movement of the arm or lever 7 forces the hooks 5 and 6 inwardly and into a biting engagement with the opposite margins of the rail-base. Now, with t e three hooks or lugs 568 powerfully gripping the edges of the base-plate, the plate with its head 9 is secured rigidly and immovablv against the under side of the rail, and the rail is thus prevented from slipping or creeping by reason of the contact of the head 9 with the side of the cross-tie.

In that modification of my device illustrated in Figs. 2 and 4, the hook or lug 8 instead of being sprung over the edge of the rail-base, is, by means of a wedge 10, inserted between the hook 8 and the edge of the rail-base, caused to swihg outwardly, with the same effect upon the hooks 5 and 6 as above described. The wedge 10 has a downwardly turned'flange or head 11 by means of which the wedge may be powerfully driven into place. The three gripping points are now at the hooks 5 and 6 and the straight inner edge of the wed c 10.

It will be understoo that the device here described may be readily attached and may be as readily removed by the use of a tool as indicated, or by driving out the wedge 11. It will also be understood that these anticreepersare applied to both rails of the track at suitable distances apart, and that they may, if desired, be reversed or doubled in such fashion as to prevent the movement of the rail in. either direction.

Havin described my invention, what ll claim an desire to secure by Letters Patent,

1. A rail anchor comprising a plate have at one end a hook adapted for engagement with one margin of the fige o a track-rail, having at its other end a hook adapted for en agement with the opposite margin of said ange, having also an extended resilient arm normally disposed at an angle to such plate, said extended arm having at its outer extremity a hook adapted to be sprung into operative engagement with one of the flanges of said rail.

2. In a device of the described character, a cross-tie,'a track-rail upon the tie, a plate beneath the'rail-fiange, said plate having at one end a hook engaged with one mar of the rail-flange, having also at its other end a hook engaged with the opposite "Till of the rail-flange, having also a head wch contacts with the side of said cross-tie, hav-- RAY J.
