My invention relates to rail anchors and has for its principal object the provision of a one-piece anchor device of improved. construction, whereby the device is tensioned during its application to a rail so as to exert a strong resilient grip, both vertically and transversely of the rail base.

Another object is to provide ail-anchor having thecharacteristics above referred to, which can be applied by driving it transversely of: the rail base from one side thereof, and which is so constructed that an anchor of one standard size may be applied to rails of dilierent sizes.

anchor construction which exerts both v-er tical and transverse spring grips on the base of the rail, which maintains the maximum tension to which it is subjected during its application, and. which increases the grip of the device both vertically and transversely of the rail when the device is subjected to creeping pressure.

The invention consists of such further new and improved construction as will be hereinafter described and claimed for carrying out the above stated objects and such other objects as will appear from the follow ing description of the embodiment shown in the accprnpanying drawing.

In the drawing:

The embodiment of my invention shown larly disposed U-shaped jaw 15, thefree Another object is to provide an improved distance between the shoulder. 11 and theapplied, so that it is necessary to tension the railroad rail. The straight body portion 10 .5 of the bar normally bears againstthe' bot-9 tom surface of the rail and is bent down- 5 wardly and upwardly topro'vide a loop 14. The said loop is so positioned with respect to the shoulder portion 11 that the upstand'e ing arm 14' of against the vertical edge of the rail base at the opposite side of the rail. The up standing arm 14 is bent to provide an angu r end 16 of which is bent, downwardly wto x;

provide a vertical arm 14* which. aligns with the arm 141.- The arms 14, 14* are disposed on opposite sides of the body por tion 10, so as to contact with. the edge of the rail base at points on opposite sides of the body. This arrangementserves to hold the straight body portion 10 of the anchor in a position substantially at right'angles to the longitudinaledges' of the rail base so that the engagement of the shoulder ll with the opposite edge of the rail base will be at it a point substantially midway between the; said arms 14, (14: The jaw portion 15' so formed with respect to the body portion 10 of the anchor that the verti'rsl dis tance between the jaw and said body per tion, when the anchor is free of the rail, is normally less than the thickness'of the rail base at the point engaged by said mem bers when the anchor is in itsapplicd posi tion, whereby -it is necessary to force the said jaw and body portion apartwhcn driv mg the anchor to its. applied-position. Tli e' upstanding arms 34-. ll" when the anchor is free of the rail, is norn'mlly less than the width of the rail base to which the device loop portion of the anchor when forcing the shoulder 11 over the edge oi: the-rail base. i

In applying the anchor to a rail, the jaw",

portion 15 is hooked over one base flan e of the rail in a position adjacent one ot the cross ties 17, so that one of the arms 14 lel, will'bear against the vertical face of Q the cross tie. The anchor is then=driven;- from the initial position shown in dotted. lines in Fig. 2, tothe applied'po sitiofi b I striking the loo portion of the anchor 1 ,1 asledge. The roe'of theblow against the loop portion body portion 't-h the loop normally bears.

- 15 upon the inclined surface vice versely of the rail until the shoulder pcrtion 11 clears the edge 18 of the rail base, whereupon the said shoulder snaps into, en-

agernent with the vertical face of the base ange, The transverse movement of the body portion 10 of the anchor reduces the diameter of the loop 13 andtherebyt tensions the anchor so that the upstanding arms 14:, 14* and the shoulder 11 exert a streng spri-pg grip on opposite GdgeSlOf the rail base. The hammer blows against the loop, in addition to driving; the body portion transversely of the rail, force the jaw of the rail base.

lhis movement of the jaw tends to f further. tension the loop portion of the anchor so as to exert a strong spring grip of the jaw and body portion 10 upon the top and. bottom surfaces respectively, of the base flange l2 of the rail base. The tendency which the spring loop has to expand to theposition from which it was sprung, exerts a strong spring pressure through the 'jaw 15 and body 10, against the upper and lower surfaces, respectively, of the rail'base, and exerts a strong spring grip through the arms 14, 14 and the shoulder 11 horizontally across the rail base. The spaced arms 14,14 hold the body portion 10 and the shoulder 11in a centralized position'with reference to the said arms, and at sub-- stantially right angles to the length of the rail.

Niththe arrangement shown; any creep ing pressure tending to move the shoulder 11 nearer the tie, will increase the distortion of the loop 13 and thereby increase the grip of the device on the rail. The depending arms 14: and 1d are so positioned with respect to thebody portion'of the anchor that the anchor may be applied in its initial positiqn with one of. the said'arms in engagement with a cross tie, there being sufficient clearance between the cross tie and the upper portion of the loop 13 to permit the anchor to-be driven to its applied position without danger of striking the cent tie. The relatively large loop 13 pro vides maximum resiliency whereby the dey be adjusted to the base flange of rails 0 various ,widths and thickness, without danger of impairing the resiliency of the anchor.
