si ed to prevent .the longitudinal creeping oigilails and known as rail anchors.

This invention hasfor an object a one-piece rail anchor which is eflcient in use and easy to apply and remove, if necessary.

Another object of this invention is to provide a rail anchor the normal length of w ich 1888. Serial I0. 293,918.

adapted to extend transversely beneath the railbase flange. The body member 1, at one end thereof, is formed with a rail flangeengaging means, preferably comprising an upstanding lip 2, e inner surface 3 of which is ada ted to engage a vertical edge'of a rail -baseange. The opposite end of the body membervl is formed is greater than the width or cross-section of o d or three-ply loop member 4. The lower the rail base flange which it is intended eng e.

A rther object of this invention is vide a rail anchor having clamping means,"

said clamping means being rem'lient and yielding.

An additional object of this invention is to provide a rail vanchor having a -clam ing member which includes a yielding an resilient S-shaped, three-fold or three-ply member ada ted to engage the lower surface of A still further object'of 'this invention is to provide a. rail anchor which, when in position on a rail base flange and tilted under sufficient pressure, causes various parts thereof to contact and brace each other, increasing the rigidity of the anchor and resulting in a firm owerful bitingaction on the rail base flange ythe anchor.

- Figure 5 Villustrates a vmodification. ofthe" anchor illustrated in Figures 1 to 4 inclusive. Figure 6 illustrates another modification. Re errin'g tothe drawings and especially If desire illustrating the anchor prior to .ap-

-en 5 of the S-shaped member 4 is curvedl andconstitutes a tie-abutting means. Connected to the tie-abutting means 5 bymeans of an easy bend 6 is a substantially vertical shank 7 which terminates ina substantiall yrigid member 8 bent at an yangle to 'said shan With an S-shaped, three- 7, and adapted 'to' engage the upper surface of a railbase flange.

lThe member 8 is adapted to engage theu per surface of Va rail base flange and may be made o f any form or conf ration. In the drawings I have illustra it ashaving an angle corresponding to the base flange which it is intended to engage., The apex or upper'v surface 9 of the S- shaped member 4 is disposed beneath the member 8 a distance normally less than the cross-section orv thickness of the rail base flange adapted to be engaged thereby, and, together with the substantially ri 'd member 8, constitutes means t9 clamp an grip a rail base flange.

Normally the face 10 of the S-shaped member is positioned adjacent but spaced from .the inner surface 6 of the easy bend 6. vThe upper end 11 'of the S-shaped member 4 is in Figure 2 illustrates the'anchor constituting vclose proximity to a point 12 of the middle or second pliy 3 or vfold of the S-shaped member. the anchor maybe so constructed vangle of the rail that these'two points contact,`- The-horizon-v tal distance between the inner face y3 of the vthe width of a standard? rail base-ange.

llip 2 and the face 10 of thev Sshaped member 4 isnormally thesame as en -greater than 'Figure'.4 illustrates the'relation of parts before andafter the anchor has been' applied Also, the distance between the inner face Z'l'of f' thelip2 and the inner face of the shank 7 is greater than tliewidth of a standard rail n e. I 1 T egri tortion ofthe'various from their normal position to their position on a rail base flange. In the anchorconstituting this invention the degree of vdistortion depends on the distance between the clam ing 'elements 8 and 9 and the plane occupi by -the portion 13 adjacent the lip member-` 2. .As'

ofthe.. anchor depends on the diad l arts of the anchor lmember 8 may a distance greater made, to occuly above described, the distance between vthe clamping elements 8 and 9 is normally less than the thickness of a rail base flange to be en aged thereby.

he portion or surface 13 adjacent the lip relation of these parts any desired grip or holding force may be obtained.

'In application 'he clamping means 8 and 9 of the anchor are applied to the. rail base flan e and-pushed on as lfar as they willgo.

At t e end of this operation the anchor will assume the position illust-ratedA in Figure 3. The end 14 of the' member 8 ,will bear upon the upper surface of the rail base flange and vertical shank with a spikemaul, whereby thel the lip member 2 will be beneath and engagesome int on the under-surface of the rail base anchor, as by striking the outer face of the anchor is, distorted and the parts 8 and 9 caused to travel upon the rail base flange until the' lip 2 clears of the rail base flange In thev application of the anchor to the ra1l I base flange, the substantiall rigid member 8 and the shank 7 are force upwardly and outwardl the eas bend 6 servingas a fulcrum as s own in igure 4. At the same time the S-shap'ed member 4 is depressed, whereby the face 10 ofthe S-shaped member 4 is movedfdownwardl'y and outwardly.l During vzic the rail base lflange 'forces the end 14 of 'the thisfde'pression thev face 10 may or may not contact with the inner face (if of the easy bend 6.

Also, if sufiicient distortion occurs, the upper end 11 of the S-sha ed member 4 may contact with the middle old at the point 12. Due to this distortion', the applied pressure member 8 to travel up on the inclined surface of the rail base flange, andthe apex 9 to travel transversely on the under surface of the rail base flan e until the lip 2 clears the opposite edge 4of t e rail base flange-and' sna s into position.

y At thebeginning of t e application of the anchor to the rail base flange, due to the rais-l ing of the substantially rigid member 8, its

angle ischanged.

-Durin'g the application the inclined surface of and when the anchor snaps into position the angle of the memthe end 14 rides .upon

sufficiently to attainA -s aced ange. Pressure is then -applied to the flange the opposlte vertical edgel p and snaps into position;

spaced from the S- ber 8 is again changed and it assumes an angle approximating the angle of the rail base flange. Throughout the application of the anchor to the rail base flange the body member 1 does not substantially yield or flex. The yielding issubs'tantially confined within the clamping means 8 and 9 and its cooperatin parts, namely, the shank 7 and the easy ben 6. t

In applying the anchor it is possible to overdrive the anchor and force the inner surface of the shank 7 in contact with the vertical edge of therail base-flange. This, however, cannot occur until after the lip 2 has 'cleared the opposite edge of the rail base flange. If the anchor is overdriven to any extent', the inner face 3 of the li 2 lvvill be from the vertical edge of t e rail base ange, which it is intended to engage, a distance equal to the amount that theanchor has been overd'rjiyen. As soon as any pressure or force is applied to the tie-abutting portion 5, which will occur when the rail starts tol creep or slip, the anchor will adjust itself by shifting transversel of the rail and 'assuming its normriapplie position.

The normal positionof the anchor on a rail base flan e is illustrated in Figure 2. It will be seen t at the rail is engaged and tightly A held between the clamping means formed by the member 8 and the-apex 9 ofthe S-shaped member 4. The vertica edge of the rail base within the clamping means 8 and 9 is free and spaced from the shank 7. Also, a ortionof the under surface adjacent the ver! tical edge of the rail base' flange is free and haped member. 4. The" opposite edge of the rail base flange is engaged by the inner surface 3 of the upstand ing lip 2. Due to the disposition ofthe portion 13 and the' distance between the elements 8 and 9, the necessary upward and downward .loo

pressures to secure a firm grip are obtained. i

the shank 7 and a pressure on the apex-9. Since the member 8 is substantially rigid and does not yield appreciably, the `surface 10 under sullic1ent ressure will be forced into contact with the ace 6', thus forming a brace and restricting further tilting. In the tilted posi tion the upper rail base flange-engaging means 8, and he lower rail flange-engagingv means 9 will bite into the rail'base flangeA and effectively restrain any further slipping or movement on the part of the rail.

The modification illustrated in Figure 5 differs from 4the preferred form illustrated in Figures 1 to 4 inclusive, in that the shank 7 is substantially ,at right angles to the tieabuttin means 5. It further differs from the pre erred modification in that the outer surface 10 of the S-shaped 'member4 does not cooperate with any easy'bend to form a" brace during tilting of thef anchor. The face 10 may, however, under sufficient pressure contact with the shank 7 In'all other spects this modification is similar to the preferred form and further description thereof is deemed unnecessar The modification lllustrated in Figure 6 differs'from the preferred form illustrated in Figures 1 to 4, inclusive in that they S- shape member 44 has its middle member disposed at an angle instead of horizontally,

whereby the u per portion 41 thereof cannot I' 1. A rail anchor comprising-'a mem# contact with t e middle; member 42. In all other respects this modification is similar to the preferred form and further description thereof is considered unnecessary.- .l
