plurality of angular shaped teeth 14 adapted, when the wedge is in its applied osition, to bite into the surface of the rail ase engaged, The opposite side 15 of the Wed 0 inclines inwardly toward the center of tge rail when in its normal applied position. Preferably, the inclination of the surface 15 is slightly greater, with respect to the horizonta than the inclination of the top surface ofthe rail base. The said inclined surface 15 merges at the thick portion of the wedge with a curved end surface 16; The

end of the wedge is provided also with ln s 17 and "18 adapted to enga c with the longltudinal corner ortion of t e rail base, so as to hold the we ge against inward movement on .the base flange when the clip is being driven to its applied position. The teeth 14, biting into the surface of the rail base, prevent movement of the wedge outwardly. The clip member is made, preferably, from a piece of sprin metal, rectangular in cross section and 18%811'0 to substantially U-shaped configuration to rovide upper and v he 11 per jaw is formed with a relatively long earing surface which bears flat against the u per surface of the rail base. The lower pm 20 is so formed that, when in its applied position itbears flat against'the inclined surface 9 the wedge 10. The distance between the jaws 19 and 20 is normally less than the combined thickness of the base flange of the eing at a slightly greater angle than t e.

top surface of the rail base, brings the point of maximum combined thickness of thebase flan e and wedge at a point near the edge 7 he base flange. With such construction, the clip is driven through a condition of maximum distortion and the tension is slightly relieved before the clip reaches its applied aosition.

In or er to provide an interlocking engagement between the clip and the wedge, I preferably form the lower jaw of the clip with a recess 21, which receives a central rib 22 formed on the under surface of the wedge. The extreme end of the clip is preferably tapered, as shown at 23, to provide cam surfaces which, together with the curved surface of the wedge facilitates the application of the device to the rail.

In operation, the wedge may be positioned on either the bottom or top surfaces of the rail base, with the lugs 17 and 18 abutting against the longitudinal edge of the rail base. The clip is then driven transversely of the rail into gripping engagement with the inclined surface of the wedge and one surface of the rail base. The spring tension to which the clip is subjected in driving it to its applied position, forces the teeth 14 of the wedge into the surface of the rail base so as to prevent movement of the wedge in a direction to loosen the grip of the clip. The outward movement of the clip is resisted by reason of the resiliency of the clip and the difference in angle of the inclined upper surface of the rail base and the inclined surface 15 of the wedge.

In Fig. 5 I have illustrated another embodiment of the invention, in which the wedge member instead of being provided with the central rib 22 is formed onv its bottom surface with side flanges 2 l2 l which fit over the opposite side faces of the clip. The clip member shown in the modified construction is the same as that shown in the preceding figures except that the central groove 21 is omitted.

I claim:

1. A rail anchor comprising a wedge shaped member adapted to engage the base flange of a rail, and a clip formed with upper and lower jawsadapted to be driven transversely of the rail into gripping engagement with a surface of said rail base and with said wedge member; the angle of said wedge being such relative to the inclined top surface of the rail base that the clip is driven through a condition of maximum distortion before it reaches its applied position.

2. A rail anchor comprising a wedge shaped member adapted to engage the base flange of a rail, and which, when in its operative position, decreases in width toward the center of the rail, and a clip member adapted to be driven transversely of the rail into gripping engagement with a surface of said rail base and with said wedge member.

3. A rail anchor comprising a wedge shaped member adapted to engage the base flange of a rail and formed with a surface inclining inwardly at a greater angle than the inclined surface of the rail base, and

a clip formed with upper and lower jaws adapted to be driven transversely of the rail into gripping engagement with a surface of said rail base and of the inclined surface of said wedge member.

4:. A rail anchor comprising a wedge shaped member adapted to engage the base flange of a rail at one side only of the rail base, and a clip formed with upper and lowor aws adapted to be driven transversely of the rail into gripping engagement with a. surface of the said rail base and with said wedge member.

5.
