10 Claims.

grip on the rail, which may be applied to prevent the creeping of the rail in one direction or the other as desired and which is easy to install, which may be applied so that the locking end of all anchors may be on the inner side of the rail making inspection easy and so as to be out of the way of brine drippings, which will not be loosened by rail vibration, which will not drop from the rail when the grip thereon is loosened, which cannot spring away from the rail to loosen the wedge member, which will not spring due to the wedge being driven in too far and the anchor loosened thereby and which cannot be so stretched by rail expansion as to become loose upon rail contraction, and it consistsessentially of the arrangement and construction of parts as hereinafter more particularly explained.

Fig. 1 is a cross sectional view through the lower portion of a rail showing the anchor body applied thereto in elevation and the wedging member withdrawn.

Fig. 2 is a sectional plan view of a rail-and a portion of a tie and my anchor applied thereto.

Fig. 3 is a side elevation of the parts shown in Fig. 2.

Fig. 4 is adetail of the wedge member in end elevation.

In the drawing like characters of reference indicate corresponding parts in each ligure.

` I indicates a portion of a rail, IX and I0 being the laterally extending portions of the base iiange. 2 is the anchor body, the portion 2X thereof extending against the bottom face of the rail portion I0 to the centre of the base iiange of the rail, the portion 20 inclining downward from the portion 2X to a point approaching the outer edge of the rail portion IX from which point it extends horizontally as indicated at 21. 3 is a projection extending upward from the outer end of the portion 2X and slightly recessed at 3X to receive the edge of the rail portion I 0.

4 is a projecting portion extending upward from the opposite end of the anchor body, that is the outer end of the portion 21, and spaced from the edge of the rail portion IX. The upper end of the portion 4 is bent over on itself and preferably reduced in thickness at the point of bend 4X and extends downward therefrom to form a portion 4U intervening between the portion 4 and the edge ofthe rail portion IX. The portion 4o is preferably recessed at 4l to receive (Cl. 23S-328) the aforesaid rail edge, the lower side ofthe recess being extended at 5 to t between the anchor body portion 21 andthe lower side of the rail. The portions 4 andA 40 are spaced apart to form a slot 6 in the opposing vertical walls'of which are formed transversely arced recessesSX and 60 tapered in opposite directions.

"I .is a wedge member comprising a. plate portion 'IX forming a tie abutting piece and centrally from oneY face of which extends a plate portion l0 at right angles to the portion 1X. I1 is a-boss extending from one face of the plate 1 and having its exterior face convexed transversely and tapered longitudinally to have wedging engagement with one or other of the grooves 6X and 6.

The end of the wedge formed by the plate portion IX it butted up against that vertical face of the tie which opposes thedirection of traiiic over the rails I. The body of the rail anchor, when the wedge'll is entered into theL slot 6, is driven towards the tie, the intervening vportion 4 being thereby forced towards the rail so that the edge of the portion IX is thereby gripped atone side of the rail and the portion I0 gripped by the por tion 3'at the opposite side of therail.

If there is any tendency for the rail to creep in the direction of arrow, the rail body is carried with the rail in the same direction forcing the abutting plate 'IX against the tie and the wedge farther into the groove 6X.

It will be seen that il' it is desired to prevent creeping of vthe rail in they opposite direction to arrow the anchor is placed at the opposite side of the tie, the tie abutting portion of the wedge bearing against such oppositeside and coacting with the groove 6 instead of the groove 6X to lock the anchor to the rail. v

It will thus be seen that they greater the tendency for the rail to creep the frictional contact between the rail and anchor body will carry such body toward the tie against which the wedging member bears and into tighter wedging engagement with such member so that the greater the tendency to rail creep the tighter will the anchor be locked thereto.

From this description it will be seen that I have devised a rail anchor which will eiectually prevent the creeping of a rail by having a positive grip thereon, which may be applied to the rail at either side of the tie and on the sameI side of the rail to prevent creep in either direction, which will not become loose due to expansion and contraction, which may be placed on the inner side of each rail so as to make inspection easy and which cannot become loose or detached.

2. The combination with the base flange of an rail and a stationary abutment adjacent thereto, of a rail anchor comprising a bar portion extending transversely beneath the rail flangey and engaging one edge thereof at', one end, an upwardly extending portion at the opposite end bent back upon itself to engage the other edge vof the rail flange and having vertically vdisposed opposing transversely recessed surfaces, and a wedge extending between such opposing surfaces and engaging one or other of said recesses and bearing against the abutment at its driving end.

3. The combination with the base flange of a rail and a stationary abutment adjacent thereto, of a rail anchor comprising a bar portion extending transversely beneath the rail flange and engaging one edge thereof at one end and inclinedly offset towards its opposite end, an upwardly extendingY portion at suchopposite end. bent back upon itself to engage the other edge of the rail flange and having vertically disposed opposing surfaces and a lateral inward extension fitting between the bar portion and rail at the base of the inclined portion, and a wedge extending between such opposing surfaces and bearing against the abutment at its driving end.

4. The combination with the b-ase flange of a rail and a stationary abutment adjacent thereto, of a rail anchor engaging the rail at one or other side of the abutment and comprising a bar portion extending transversely beneath the rail flange and engaging one edge thereof at one end, an upwardly extending portion at the opposite endbent back upon itself to engage vthe other edge of the rail flange and having vertically disposed opposing surfaces having opposing recesses tapered in opposite directions, and a wedge carrying member engaging both opposing surfaces and bearing against the abutment at the driving end of the member, and a tapered rib extending from one face of the carrying member to engage one or other of the recesses according to the side of the anchor bar from which the wedge is driven.

5. The combination with the base flange of a rail and a stationary abutment adjacent thereto, of a rail anchor comprising a bar portion extending transversely beneath the rail flange and engaging one edge thereof at one end, an upwardly extending portion at the opposite end extending back upon itself to engage the opposite rail edge and to form a vertical slot, and a wedge extending into the slot and bearing at its driving end against the abutment.

6. A rail anchor comprising a bar body adapted to engage one edge of a rail base flange, an upwardly extending portion at the opposite end bent back upon itself to engage the opposite edge of the rail base flange and forming vertically disposed opposing surfaces, and a wedge member adapted to be driven between such surfaces.

7. A rail anchor comprising a bar body adapted to engage one edge of a rail base flange, an upwardly extending portion at the opposite end extended back upon itself and having a transverse groove in such extended portion for engagement with the opposite edge of a rail base flange and forming a vertically disposed slotted opening, and a wedge adapted to be driven into such slotted opening.

8. A rail anchor comprising a bar body adapted to engagey one edge of a rail base flange, an upwardly extending portion at the opposite end bent back upon itself to form vertically disposed opposing surfaces having oppositely tapered opposing recesses therein, a wedge carrying member fitting between said surfaces and having a tapered wedge rib at one side thereof adapted to engage one or other of said recesses according to the side of the anchor from which said Wedge carrying member is driven.

9. The combination with the base ilange of a rail and a stationary abutment, of a rail anchor comprising a bar portion extending transversely beneath the rail and engaging one edge thereof at one end, an upwardly extending portion at the opposite end bent back upon itself to engage the other edge of the rail flange and having vertically disposed opposing surfaces, one of said surfaces having a transverse tapered recess, and a wedge member bearing against the abutment at its driving end and adapted to engage said recess on one side and the opposing surface of the upwardly extending portion f on the opposite side.

10. A rail anchor comprising a bar body adapted to engage one edge of a rail flange, an upwardly extending portion at the opposite end extended back upon itself to form two opposing surfaces and terminating in a laterally extending portion adapted to fit between the anchor body and base flange of a rail, and a wedge adapted to enter between the aforesaid opposing surfaces.
