@fi. 9, 1934. HARTMAN 1,976fl69 RAIL ANTI CREEP Filed Nov. 25) 1952 INVENTOR Ad [:1 11} H51 hm an Patented Get. 9, 1934 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to rail anti-creeps, and has for an object to provide improved means for locking a rail against creeping.

A further object of the invention is to provide a device which is attached by wedging action to the flange of a rail, and bears against the side of the tie, preventing the creeping movement of the rail relative to the tie.

A further object of the invention is to provide an improved type of device and wedge, which will cooperate with the rail and tie for the purpose mentioned.

The invention, therefore, comprises a member having a side opening which will fit over the edge of the flange of a rail with a part arranged to bear against the lateral side of a tie, and an improved type of wedge which will cooperate with the member for wedging the rail relative to said member, and, therefore, force the member against the side of the tie in case of creepage.

In the drawing:

Figure 1 is a perspective view of a section of a rail with the present invention applied thereto,

Figure 2 is a view of the body member of the invention in side elevation with its relative position upon the flange of the rail indicated by dotted lines,

Figure 3 is a sectional view taken on line 33 of Figure 2, and

Figure 4 is a view of the wedge member in side elevation,

Like characters of reference indicate corresponding parts throughout the several views.

The improved rail anti-creep, which forms the subject-matter of this application, is adapted to be associated with the flange 10 of a rail, which will be laid in the usual manner, as upon the plate 11 bearing upon the tie 12 and secured by the spike 13. This is merely the usual and ordinary manner of laying rails.

The present anti-creep is a device supplemental to this spiking of the rail to the tie. It comprises a body having a seat 14 fitting upon the underside of the flange 10 of the rail, and a part upstanding therefrom comprising a riser 15, an angularly disposed part 16, and a return angle 17.

The body further comprises an abutment 18 adapted to bear against the side of the tie 12, as shown more particularly at Figures 1 and 3, and for added strength, a brace 19 is preferably provided.

As will be noted, the parts 16 and 1'7 are so proportioned as to be positioned at some distance above the rail flange 10, and by reason of their angular position, to form an angular groove 20. This groove 20 is tapered throughout the extent of the body part, as indicated at Figures 2 and 3.

This taper fits the taper 21 of the wedge member 22, which is preferably provided with a driving head 23, as shown at Figures 1 and 4.

In operation, the plate 18 is driven into the ballast until the underside of the flange 10 is properly seated upon the seat 14 of the body, and the plate 18 bearing against the side of the tie 12. The wedge member is now inserted upon the top of the flange 10 and through the angular groove 20, and is driven home by the use of a sledge or other driving implement.

The driving of the wedge member 22 serves to clamp the body member more tightly against the side of the tie than it originally assumed, so that any creepage of the rail in the direction indicated by the arrow, will be resisted by the body member bearing against the side of the tie, and such creepage will serve to increase the tightening effect of the wedge upon the body member.

Of course, the rail anti-creep herein illustrated may be modified and changed in various ways without departing from the invention herein set forth and hereafter claimed.

The combination with a tie and a rail thereon, of a rail anti-creep comprising a plate part fitting against the side of the tie, a part extending away from the tie and including a rail seat, a hooked member overhanging the rail flange, said overhanging member being substantially as long as the seat in the direction of the length of the rail and having an inverted V-shaped groove, and a V-shaped wedge driven into locking engagement between the groove and the flange.
