Application filed June 5,

T oall'whomitma-y concern: 7

Be it known that I, ROLANDIS A. BLAIR, a citizen of the United States, residing at Fort Wa ne, in the county of Allen and State of ndiana, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification.-

My invention relates to rail anchorin devices and has for its object, the provision of a new and improved rail anchor which when applied to a railroad rail, in a position to abut against a stationary partof the roadbed, will prevent the rail moving longitudinally in the direction of the tratlic passing over it, and which will not be loo-sened or displaced by the vibration of the rail, counter-creeping, or other influences to which devices of this character are subject-. ed while in service.

A specific object of the invention is to provide an improved one-piece rail anchor which may be applied to rails having base flanges of difierent widths and thicknesses, which will grip opposite edges of a rail base, naintain its initial osition on a rail by sp ing pressure and w ic-h will be inexpensive to manufacture.

A further and more specific object of the invention is the provision of a one-piece rail anchor embodying the new and improved constructions hereinafter described and claimed for carrying out the above stated objects and such other objects as will appear from the following description.

The invention is illustrated in a preferred embodiment in the accompanying drawing,

I wherein- Fig. 1 is a plan view of the rail anchor constructed in accordance with my invention applied in its operative position on a railroad rail.

Fig. 2 is a side view in elevation of the.

rail anchor shown in Fig. 1, the same being illustrated in its operative position on a rail. Fig. 3 is a view similar to Fig. 2 showing the rail anchor in one of its positions assumed during its application to a rail.

Fig. 4 is a view in perspective of the rail anchor shown in the three preceding figures. Fig. 5 is a view in perspective. on a smaller scale, of the metal from whichthe anchor is formed.

a railroad rail and 11 oneof the cross-ties,

on which the rail is supported.

The rail anchor is preferably made by bending a bar of steel to the form shown in Fig. 4 to provide ahook-shaped jaw portion 12, adapted to fit over one of the base flanges of the rail, an upstanding portion 13 for engaging the other edge of the rail base, and i a tie abutting portion 14: adapted to bear against one of the vertical faces of the. cross tie 11 when the anchor is in its applied position. The steel bar from which the anchor is formed, is preferably square in cross section and is bent at its middle to provide two substantially

parallel legs

15 and 16, as shown in Fig. 5. The bent portion 17 of the bar is bent upwardly on the line 18 to provide the hook shaped jaw 12, the extremity of the le '15 is bent upward on line 19 to provide t e upstanding abutment 13, and the extremity of the leg 16 is bent downwardly and outwardly on line 20 to provide the tie abuttin foot 14. The portion of the bar 16 beneat the jaw 12' is bent up wardly, as indicated by the reference numeral 21 in Figs. 2, 3 and 4, so as to normally stand above the upper edge of the adjacent portion of the leg 15 when the anchor is free of the rail. The recess defined by the lower edge of jaw 12 and the upper edge of the portion 21 of leg 16 is normally less than the thickness of the rail base so that the portion of the leg 16 defining said recess will be distorted during the application of the device to the railand will, therefore, exert a spring grip on the upper and lower surfaces of the rail base, when the. anchor is in its operative position.

With the above construction, the maximum distortion efiected during the application of the anchor to a rail, is confined to theportions of the leg 16 defining the recess receiving the base flange, these portions of the leg 16 being-indicated in Fig. 2 by the reference numerals 22 and 23. The distance between the inner face of the abutment 13 and the vertical surface 24 of the jaw 12 is preferably slightly greater than the width of the rail base so as to accommodate rails of varying widths. If there is any appreciable clearance between the said surfaces ting portion 14 is preferably bent at an angle with relation to the leg 15 so that it will bear fiatwise against the tie 11 when the anchor is in its normal diagonal. position.

In applying the anchor to arail, the jaw '12 is fitted over one of the base flanges of to take a shackle hold on opposite edges ofthe railbase by driving the end' 13 of the anchor toward the tie 11. During the application of the anchor to a rail, the leg 15 of the anchor is stressed,though this stress is somewhat relieved when the abutment 13 snaps over the opposite edge of the rail base. The portions 22 and 23 of leg 16 will also be stressed during the application of theanchor to the rail and will maintain their maximum distortion when the anchor is in its applied position, thereby insuring a firm spring grip gn the upper and lower surfaces of the rail ase.

While I have described my invention in a specific embodiment, it will be obvious that various structural changes might be made in a device of this character without departure from the spirit of the invention. I therefore Wish it understood that 1 contemplate all such structures as come within the scope of the following claims.
