l Referring more particularly to the draw- 1ngs, and especially to F igs.,1 to 3 inclusive, 11 designates the ase of a railroad rail having .a ilat lower sur-face 12 and an upper surface 13 sloping upwardly from the edges tothe web 1d.

The .aiichor comprises a body portion 15 extending transversely of the rail and lying under and close against the base. rilhis body l5 is longer-than the width of the rail base and is provided at the ends with uptur'iied portions 16' and 17, the former o-which may be bent slightly toward the rail and which isl designed lto engage the edge oi' the rail base, so ,that the latter projection 17 is spaced away iromthe rail. A pair of downwardly projecting ilanges 18 are provided arranged one on each side of the body 15 and extending from substantially the projection .17 for a suitable distance under the rail base: These 'danges 18 are the move- `ment resisting shoulders of the anchor and are adapted for engagement with a tie. The

body carries an upward projection. or ful- Crum member 19, which springs upwardly a short distance from the edge of the rail base, and is preferably out of normal to the anchor body. lllie .ulcruin member 19, as

. shown-in the drawings, is at right angles to the upper surface of the rail ,base but it will be understood that this particular angle is not necessary and that the fulcruni may even be `lformed normal or perpendicular to the anchor body. As will be clearly seen,the rail base fits easily between the parts 16 and 19 with aV small amount of play allowed. The fulcruin member 19 is apertured at 20 for the passage of a key 21. The projection 17 forms a seat for the lrey and, to guard against dislodginent oi the key, may be slightly recessed as at 22 in the key re* l ceivingportion, so that the key will be einbraced between the upstanding lugs 23.

The anchor is preferably formed ot stamped sheet metal, as illustrated, but may be cast or forged. ln Athe stamped constructionshowm'the tulcrun 19 is struck up or displaced from the body between the flanges 18, thusleaving an opening' 24 outside the rail base. When the device is a casting, the

resisting shoulders 18 may besupported by y any suitable number of transverseribs 25 eX- tending between them, as indicated in l41 ig. 8.

For certain purposes, the body 15 may ii de.- s'ired be'cu siert at say the line26. The key 21 is formed or dat 'springfsteel and may be provided with a rounded edge 27 at one end on one side and at the opposite end on f rounded leading edge which will slide over the rail base without scoring the same. As

previously stated, the key is normally straight and is bent to the form shown when driven' up on the rail base.

In Figs. l1 and l'the anchor body, designated 115, takes the form of a tie plate,`the rail abutting rib 116 replacing the upturned body end 16. of. Fig. 1. The fulcrummember 19, key seat 17 and key 21 are formed as already described. rlhe resisting -shoulders '18 of the body are replaced by the usual tie engaging ribs 118 on the bottom ofthe body which bite into the tie, and also-by spikes which will pass through apertures 128 and into the tie in the usual manner.

In the vmodification shown in Figs, 6 and 7, the anchor body takes the form of a tie spacer 215, the part 16 being replaced bythe rail abutment 216 and the resisting shoulders 18 by the specially shaped resisting shouldersor. -flanges 218', which extend between and against the ties o-f a bridge or the like. ln this particular form, the fulcrum member 19 and'key seat 17' are illustrated as connected by ribs 229 which support the fulcrum member, the key seat and the body betweenthe two'in addition-to the support furnished'by the flanges 218.

From the foregoing description, it lwill be seen' that the inventionmay be arranged in a variety of ways to meet a variety of re-` quirements without in 'the least modifying the principle -of construction. An anchor proper'formed according to this invention is compact, durable, eiicient, inexpensive and easilyappj'liedand removed. VIn construction where tie'plates or tie spacers are necessary as well as rail anchors, the two may be combinedfin'one, thus effecting great economy of both capital and operating expense.

The'operation of the device is extremely simple. The anchor in any of its forms comprises only two pieces. The body is slipped under the rail and the projectionlG or its equivalent in the other i forms engaged against the edge of the rail base. The key is inserted and'. driven over. the sloping upper surface o f the rail` base, which transforms the'simple straight key in effect into a wedge and tightly clamps the anchor against the' lower surface of the rail. When properly driven, the key will be will be fulcrumed inthe part 19. T e fulcrum member is preferably inclined, as shown, for a particular reason, namely, that in driving the key there is 'a tendency to swing the fulcrum member toward the rail, which swing raises the upper edge of the aperture 20 against which the key bears and slightly bent, as shown in the drawings, andtends to loosen the key duringdriving. lf the key has any tendency 'to back down the slope of the rail base, its frictional engagement with the fulcrum will tend to carry the fulcrum with it and thus swing the bearing V line down, producing a tightening of the grip. lf the fulcrum 19 were perpendicular at thecommencement, itis obvious that it would tend to tighten/during driving of the key and to loosen the keyupon any tendency of the key to-back out. It therefore follows that thebest results are obtained when the angle between the upper surface of the rail base and the fulcrum member is 90o or more. The above statement applies only when the thickness of rail base, thickness'of key and height of .key seat are in the proper relation to bring the bearing line between the keyand the fulcrum at the upper outer edgeof the fulcrum aperture. If the key seat is too low, the key too thickor the rail base thicker than the anchor was designed for, the bearing may be transposed to the upper inner edge of the aperture, with the result that the operation will not necessarily .be'as described. The anchor proper is in direct compression between the rail and the ballast, so that pounding on frozen ballast will `not have any loosening or dislodgingeffect. The anchor presents plates 18 edgewise to the direction of drainage, so that drainage of the track is not interfered with in any way. The key being arranged transversely of the rail is not subject to dislodg ment by accidental blows from objects moving along the track. The location of the key above the rail base and -transversely thereof renders itfexceedingly easy to drive and also removes all possibility of it becoming loosened by contact with the ballast. The key being driven transversely of and toward the rail, its tip end is protected against blows in the driving out direction by the web and head of the rail.

Having thus describedour invention, what 110 we claimv is f 1: A device of the class described comprising a body adapted to engage the under surface of a rail base, a fulcrum lmembercarriedby the body adjacent the rail edge, a 1'15 vkey seat carried by the body abve the `plane thereof, and a key passing through said fulcrum and adapted to be supported at one y end on the upper surface of the rail base and at the opposite end on the key seat.

2. A device of the class described comprising a body adapted to .engage'the under surface of a rail base, a fulcrumy member carried by the body adjacentthe rail edge and disposed at an angle of not less than90 125 to the upper surface of the rail base, and a key passing through said fulcrum and vadapted to be supported at one end on the upper surface of the rail base and at 3. A device of the character described comprising a body adapted to engage the under surface of a rail base, a fulcrum member carried by the body adjacent the rail edge and a key passing through said fulcrum and adapted to be supported at one end on the upper surface of the rail base, and at the opposite end on the body and on the side of the fulcrum remote from the rail base', the relation between the points of support on the rail and body being suoli that the key normally occupies a position out of perpendicular with respect to the fulcrum.

4. A device of the character described comprising a body adapted to engage the under surface of a rail base, a fulcrum member carried by the body adjacent the'rail edge, and a key passing through said fulcrum and adapted to be supported at one end on the upper surface of the rail base, and at thegopposite end on the body, the arrangement being such that the angle above the key between the key and that side of the fulcrum adjacent the rail is greater than 900.

5. A device of the `character described comprising a body adapted to engage the under surface of a rail base, a fulcrum member carried by the body adjacent the rail edge, and a key passing throughl said fulcrum and adapted to be supported at one end on the upper surface of thevrail base and at the opposite end on the body, the said fulcrum being disposed in such relation to the key that fulcrum oscillation toward the rail induced by driving of the key will raise the fulcrum point above the key, and fulcrum oscillation induced by key withdrawal will swing the fulcrum point downwardly upon the key. l

6. ln a device of the class described, a

body adapted to engage the lower surface of a rail base, an upward projection at one end thereof adapted to engage one edge of the rail base, an upward projection at the opposite end spaced from the opposite edge of the rail base, an apertured member project ing upwardly from the body adjacent the second edge of the rail base, and a key passing through said apertured member and adapted to rest toward its ends upon the upper surface of the rail base and upon` said second projection.

7. A device according to claim 6, in which the apertured member lies in a plane approximatelyfat 90 to the inclined plane of the upper surface of a rail base.

S. In combination with 'a device according to claim 6, upwardly projecting lugs at the ends of said second projection adapted to hold the key against lateral movement on said projection.

9. A device according to claim l, in which the key is resilient and adapted to be flexed between its points of support on the rail base, fulcrum and body.

l0. In a device of the character described, a body adapted to underlie a rail base, a fulcrum member carried by the body and movable relatively thereto, anda key passing through said fulcrum memberand adapted to be tensioned between said body, fulcrum and rail base, the fulcrum being movable by the key in a direction to relieve key tension during driving in the key and to increase key tension during reverse movement of the key. l l

In witness whereof, we have hereunto set our hands.
