I Application filed Decembe 24, 1326, ,Serial No lfifijfi'hfl v 'Tht's'inve'ntio n relates to improvements in railway rail anchors of the type applied to the-toot otthe rail and incontact with the tie for the purpose or preventing creeping of the rail. The object of the improvement is to provide a rail anchor constructed of a single piece of metal and so formed as to admit of its being sprung into position on the rail. Another object of the invention is to so construct the anchor that it will remain firmly clamped in connection with the foot of the rail and not be effected by vibration.

These objects are accomplished by the construction illustrated in .the accompany ing drawings, in which F 1g. 1 1s a cross section of a railway rail with an anchor embodying the invention applied thereto and Fig. 2 is an elevation showing the rail and anchor in a plane at right angles to that of Fig. 1.

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters.

The invention consists of an anchor made from a bar of spring steel and formed with a straight arm 1, with a hook '2 at one end of the arm and a contiguous spring bow 3 at the opposite end of the arm, there being formediat the end of the bow a T-headthaving slotted side jawsospaced apart so as to accommodate the arml therebetween. Each jaw 5 has in its inner edge a. slot filocated so that the upper face of the arm 1 is spaced slightly above the bottom of said slots, whereby the arm is held in contact with the bottom of the rail when the jaws are applied, to the corresponding flange of the rail. The bow 3 is made of greater width than the T,

head so that each side of the bow extends in a vertical plane spaced from the vertical plane of the corresponding jaw. v I In utilizing the invention the jaws 5 are first applied to one of the flanges 9 of the railway rail 8 with the arm 1 extending un der the rail, andthe hook 2 is then sprung outwardly so as to clear the edgeofthe flange 7 of the rail by applying force against the opposite end of the arm 1, whereupon, by

elevating the arm the hook is sprung into position on the flange 7 When the anchor is thus positioned the arm l is held flat against the foot of the rail, and the T-head a with which thev arm has Sliding con -act grip the rail under bears againstthebottom face ofsaid arm, and. the tension of thespring bow is such that the jaws are forcefully held in'position on the flange 9 of the rail. In this manner the foot of the rail is gripped between the hook 2 and the slotted jaws 5 with resistant force exerted by the spring bow.

In applying the anchor to the rail it is so placed that the one side of-the'bow bears. against the tie 10 so that endwise movement of the. rail in one direction is thereby ob.- structed. "When the rail tends to creep, the

' spring bow 3 bears with more or less force' against the tie which tends to tilt the cross causing a binding action upon the arm' between the bottom of the rail and the top of the T-head, and a corresponding binding actionupon the flange 9 of the rail between tween the rail and anchor is frustrated. What I claim is i the arm and the jaws. Thus, slippage be-' 1. A rail anchor made of a single piece of spring plate metal formed with a straight arm with a hook at one end thereof and a contiguous spring bow at its opposite end; a T-head formed at one end of the bow,

which head has sliding contact with said arm; and a pair of slotted jaws extending from said head and spaced apart for the reception therebetween of said armysaid slots being so" located that the bottom of each slot extends in a plane lower than the top of said arm. 7

2. A railway rail anchor madeof abar of spring metal, one portion'of which constitutes a straight arm with a hook atone end Y 7 with the opposite end of said arm constituting a spring how, there being formed at the" end of thebow a pair of slotted jaws be-l' tween which said arm extends,' "said hook and the jaws-being applicable to the oppoa site flanges ofthe foot of the rail so as to resistant force applied by said how. V w 3. Arailway rail anchor one portion of which constitutes a hook arm, that portion contiguous with said arm opposite the hook,

thereof, that portion of the bar contiguous constituting a spring bow, there being at the end of said bow a pair of spaced jaws between which said arm extends, the hook.

of said arm, and said jaws beingapplicable to the opposite flanges of the foot of the rail so as to grip said rail under resistant f r e applied by said pring hormone f aid flanges of the rail and said arm being clamped between the end of said bow and said jaws.

4. A railway rail anchor having a spring bow, a hook arm contiguous with said how; anda pair of slotted jaws extending from that end of said bow opposite the connection of said bow with said arm, said jaws being spaced apart and extending ast-ride said arm, sald aws belng applicable to one flange or the rail, and said hook arm extendlng beneath said rail and engaging the opposite flange thereof, said hooked arm and jaws having grlpping relation with said flanges under resistant force applied by said spring In testimony whereof I afliX my signature.
