Dec. 6, 1932. G. 1 MOORE ET AL RAIL ANCHOR Filed April 25, 1930 'Patented- Dec. e, 1 '932 UNITED STATES PATENT OFFICE GEORGE LOOP MOORE .AND JAIEB BGBEBT STEELE, F OWEGO, NEW YORK' .ANGHOR y Application illed April 28,

Our invention relates to improvements in rail anchors or anti-Creeper devices for railroad rails.

. The object of our invention is to provlde a one-piece self-locking anchor which will grip the rail with great tenacity and prevent the creeping thereof.

Our invention comprises an anchor formed from a single piece of metal having the proper amount of resiliency which is bent at each end thereof and adapted to bear with considerable pressure against the rail above the iange at one side of the rail and against the edge of the iiange at the other side of the rail when the anchor is applied to a rail.

The novel features of our invention will be more fully understood from the following description and claims taken with the accompanying drawing in which:

Fig. 1 is a side elevation of the anchor illustrating its initial position when applyin itto a rail. iig. 2 is a side elevation of the anchor in its applied position on a rail.

F1g. 3 is an end view of the anchor as applied to a rail.

Referring to the drawing, l10 designates a rail supported on a tie plate 11 carrled by a tie 12. An anchor made in accordance with 30 our invention, as shown in the drawing, comprises an under rail portion 13 having .an inwardly bent flange overhanging portion 14 and an upwardly directed toe portion 15.

The under rail portion 13 comprises at one end a downwardly curved section 16 which continues in a loop upwardly to the ange overhangin portion 14 and at the other end a downwarly'curved section 17 which continues in a loop upwardly to the toe portion 40 15. A. li 18 may be provided on the inner vertical ace of the toe` portion 15. A sub stantially straight section 19 is preferably provided intermediate the sections 16 and 17. The end 20 of the portion 14 is preferably curved upwardly with a radius which is substantially equal to the radius of the fillet 21 which connects the ange 22 and the web 23 of the rail.

A substantially flat surface 24 is provided on the anchor adjacent. the portion 14. This 1930. serial NQ. 446,511.

surface and the upper surface of the section 19 are so shaped and disposed with respect to each other that theywlll be brought into close contiguity with the upper surface of the rail fiange andthe under surface of the railbase, respectively, when the anchor is applied to its effective position on the rail, as hereinafter set forth.

Our anchor is adapted to be applied to a rail adjacent the side of a tie by placing it transversely thereon with the curved portion 20 abutting the surface of the rail in the vicinity of the fillet 21. The anchor is so shaped that when it is placed on the rail, in its initial position, as shown in Fig. 1, the shortest distance between the curved surface 20 and the face 25- of the toe portion 15 is less than the shortest distance between the surface of the iillet 21 and the edge of the iange of the rail at the opposite side7 and preferably the distance between the curved portion 20 of the anchor and the section 19 is such that the anchor canbe placed into its initial position on the rail with little eifort; that is the curved portion- 20 can be placed in abutment with the fillet 21 without any material distortion of the anchor.

It will thus be seen from Fig. 1 that when the anchor is in its initial position it more or less hangs on the rail and the upper end of the toe portion 15 is contiguous with the base of the rail at a point somewhatshort of the contiguous edge of the rail base. When the anchor is struck a sharp blow with a hammer or other suitable implement at the point 28 in the direction of the arrow the metal in the loop portion is sprung and the toe portion 15 snaps over the edge of the rail base as shown in Fig. 2 and the anchor thus distorted securelyland effectively grips 90, the rail by virtue of lts tendency to assume the condition from which it was sprung.

It will be noted that in this position the shortest distance between the curved surface 20 and the face of the toe portion 15 of the anchor is greater than the distance betweenV these same portions before the anchor is a plied to the rail, so that, as the anchor ten s to assume its normal condition, its resilient action presses the curved surface 20 against the rail above the flange on one side and the face of the toe portion 15 firmly against the contiguous edge of the rail flange on the other side of the rail and therefore the anchor securely and effectively grips the rail.

When the anchor is in this position, that is as shown in Fig. 2, the upper surface 27 of the straight section 13 is in close contiguity with the under side of the base of the rail; the surface 2l is in close contiguity with the upper surface of the flange of the ra1l, and the under rail curved portions 16 and 17, lwhich depend below the straight section 13, are so positioned that when the rail begins to creep under service conditions the portions 1G and 17 will firmly engage the side face of the stationary tie 12 and the anchor will tend to tilt about a horizontal axis. This tilting action causes the upper surface 27 of the straight section 13 to press firmly and upwardly against the base of the rail while it causes downward pressure of the section 24 upon Ythe upper surface of the flange of the rail, as well as a resultant increased pressure of the face of the toe portion 15 against the contiguous edge of the base flange of the rail.

lVhile we have shown our invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and we desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set lforth in the appended claims.
