Application filed. April 1t, 1913. Serial no. vane-55,,

To all whom it may concern:

Be it known that I, DAYID C. STEPHENSON, a citizen of'fthe'Unite'd States, residing at Toledo, Lucas county, Ohio, have invented a new and'u'seful Improvement in Track- Anchors, of which the following is a specification, reference being had to the accoms panying drawings, in which- Figure 1 shows an elevation of my device applied to the base of a rail; Fig. 2 is a plan thereof; Fig. 3 is a side elevation thereof; Fig. 4 is a detail of the wedge member; Fig. 5 shows an elevation of a modified form of my device, Fig. 6 a plan thereof, Fig. 7 a side elevation, and Fig.- 8 a section on lines VIII-VIII of Fig. 5.

My invention relates to anchors for railroad tracks and is designed to provide a simple, eifective and positive means for anchoring the rail to the trackway, and to prevent the rail from creeping.

My invention also consists in the construction and cooperation of the parts which I shall hereinafter describe and claim.

Referring to the drawings, A indicates the rail, B the fastener plate, C the wedging member and D the tie. The fastener plate has on one end a lip 2 adapted to engage a base flange 3 of the rail A and at the other end a projection 4 having an undercut face 5 extending longitudinally of the plate and inclined toward the web of the rail. The wedge C is adapted to engage the other flange 3 of the rail A and has a lip 6 overlying the same. The face 7 of the wedge opposite the lip 6 is inclined to cooperate with the undercut face 5 of the projection 4. Depending from the broad end of the wedge is an abutment 8 adapted to bear against the tie D, and 9 is a strengthening web connecting the abutment and the wedge. The forward end 10 of the wedge C is reduced and is adapted to be bent to cotiperate with the curved or inclined keyway 11 in the. projection 4. The numeral 12 indicates a driving boss on the fastener plate B.

y the plate B underneath the rail base in such manner that the lip 2 will engage the base flange 3 of the rail. 1 then insert the smaller end of the wedge into the guideway between the undercut face 5 of the projection 4. and the base flange 3 of the rail, and move the plate and the wedge C toward the tie D in such manner that the abutment 8 will en- 01' the plate from device is assembled as follows: I pass gage against the side of the tie D. I then drive the fastener plate'B back on the wedge C by sledging against the boss 12. This causes the wedge to move relatively forward in the guideway between the face 5 and the base 3' of the rail flange and to wedge the rail solidly between the lip 2 and the inner face of the wedge. At the same time the curved keyway 11 and will bend there through, thus locking the wedge securely in the position in which it has been driven between the projection A and the rail fiange3, which will thus prevent either the wedge becoming loosened from their engagement'with the rail.

the v bendable end 1.0 of the wedge G will engage It will be seen that the longitudinal thrust,

of the rail will simply force the wedge farther into its guidewav between the projection 4 and the rail flange 3', and that such movement will merely serve to tighten and make more secure the engagement of the anchor with the rail. If it becomes necessary at any time to remove the anchor, this can be done by sledging the abutment 13, positioned on the upper surface of the projection 4, in the opposite direction from that in which it is driven u on the wedge. This will force the bent on 10 out of the curved guideway 11 and release the anchor from its engagement with the rail.

In Figs, 5 to my device, in which the bendable locking means 10 is made separate from the wedge and coiiperates with a curved guideway 11' in the projection 4:. This bendable locking member 10 has a head 14:, which engages the rear face 15 of the wedge and holds it in looking position when the member 10' has been driven home in its keyway 11.

It is obvious that my invention is not limited to the particular form of fastener and key members shown herein, since What I claim is:

1. In a track anchor, a fastener plate adapted to engage one flange of the rail, 2. rail-engaging member adapted for insertion between the other flange of the rail and the plate, the said members being adapted to 8 I show a modified form of a operation therewith bendable locking means adapted to be bent through an inclined key- Way on the oiher of said members.

2. In a track anchor, a plate adapted to engage one flange of the rail a tie-engaging member having an extension for insertion between a flange of the rail and the fastener plate, a keyway in the fastener plate, bendable locking means cooperating with said tie-engaging member adapted to be bent in said keyway for locking the said tie-engaging member in wedging engagement with the rail and fastener plate.

3. In a track anchor, two membersnnovable longitudinall of the rail for engaging opposite flanges -t ereoi" one of said members having a tie-engaging portion, a wedge portion, one side of the wedge portion engaging a rail flange and the other side engaging the other member, and a bendable locking portion, the bendable locking portion cooperating with a curved guideway on the other of said members.

i. In a track anchor, a fastener plate having a plurality of projections on the upper 1,1oc,eae

said wedge having an abutment for engagement with a tie, and bendable locking means cooperating with said wedge and a keyway for lockin together the fastener plate, the wedge an therail.

5. In a trackanchontwo members motable longitudinall of the rail for-engaging opposite flanges't ereof, one of said members having a plurality of upwardl extending projections, one of which is-a apted to engage a rail-flange, the other member having a tie-engaging portion, a wedge portion adapted to engage an upwardly-extending projection of the other member and-a bendable locking portion cooperating with a curved guideway on the other of said members.
