RATL ANCHOR.

Application filed November My invention relates to rail anchors of the general type adapted to engage the base flanges of a rail at opposite sides of the rail.

The principal object of the invention is to provide an improved anchor of the above general type, which may be driven into firm wedging engagement with one iiange of the rail base, and which is provided with a jaw portion so formed as to provide a resilient gripping engagement with the other flange of the rail base, so as to hold the device against reverse movement and thereby prevent accidental loosening of thev said wedging engagement.

Another object is to provide an improved one-piece anchor device provided with a jaw adapted to be driven into firm wedging engagement with one flange of the rail base,

l and provided. `with a portion which is torsioned during its application to a rail to effect a spring grip of the d-evice on the rail base so as to holdL the device in operative position thereon, the device being so formed as to be moved bodily, transversely of the rail to its operative grippingposition. Y

The invention has for further objects the novel arrangement, construction and comination of the various elements of thc anchor device hereinafter described and claimed for carrying out the above stated objects, and suoli other objects as may appear from the following description.

Fig. 5 is a perspective of the improved anchor shown in the preceding figures. j

Referring 'to the dra-wing, 1() designates a railroad'rail and 11 and 12 the base flanges of the rail supported on a cross tie 13.

rlhe embodiment of my invention shown in the drawing consists preferably of a yoke 1e, the upper portion of which is cut away to provide a rail base receiving recess 15,

and to provide

jaws

16 and 17 which engage the inclined top faces of the base flanges the rail at opposite sides recess is made l rger than railbase, so as to permit the yoke to be i hooked over the rail base at any desired` of the rail. The the width of the versely of the rail base, hooked over one flange of upon the end of the jaw m may be readily said base, whereay then be forced down against the top surface of the bli@ flange 11 of the rail by a tiltincmovement of the yoke in the opposite directioin.

rllhe aw i7 preferably entends in the plane of the body and the lower edge 19 thereof inclined upwardly to correspond to the inclination of the top surface of the rail base.

The portion of the recess 15 below the jaw l? is of euch size that the lower edge of the jaw 17 and the edge 20 of the yoke are forced into firm w'edging engagement with the top and bottom surfaces of the rail base respectively, when the anchor is driven to its applied position.

The anchor is made preferably of ilat steel of any suitable degree of resiliency and the body portion is given a no rmal torsional set intermediate the jaws, so that it is neces ary to twist the yoke in a direction tending to straighten ont the torsional the end edge of the rail base.

set, when moving 2l of the anchor to a position which will permit the jaw 17 to pi iss over the upper rib lill) CTI In application of the device to a rail, the yoke is tilted so as to permit the jaw 16 to ,be hooked over oneflange of the rail base,

for example, flange 11. rlhe end 21 of the anchor may then be raised to a position opposite the flange 12 as shown in dotted lines in Fig. 2 of the drawing. i suitable wrench may then be applied to the end Q1 of the anchor and the anchor twisted in a direction tending to straighten out the torsional set. This tensioning of the anchor forces the end of 16 into a firm spring gripping engagement with the top face of base flange 11. Then the end 21 is in a position substantially perpendicular to the bottoni surface of the rail base, the anchor may be driven transversely of the rail from the position shown in Fig. 3 to the applied position shown in Fig. Ll. ln the latter position the jaw 17 and the lower edge of the recess l5 have a tight wedging engagement with the upper and lower surfaces of the rail base. Vhen the anchor is driven from the position of Fig. 3 to the position of Fig. et, the angular jaw 16 rides down the inclined surface of the base flange 11 and thereby partially relieves the tension of the yoke. The remaining tension of the yoke, however, will be suf'- ficient to maintain a firm grip of aw 16 on the rail and thereby prevent the anchor moving in a direction to loosen the grip'of the jaw 17 Any movement of the anchor relative to the rail toward the left of is. resisted by reason of the fact that such movement tends to force the jaw 16 upon the inclined surface of the rail base so as to increase the torsion of the yoke.

The anchor, if desired, may be applied to the rail a short distance away from cross tie and be then driven longitudinally of the rail so as to bear flatwise against the tie at right angles to the leng h of the rail. Willen the anchor is applied in this manner, it is preferably driven longitudinally of the rail so as to bear against the tie before the jaw 17 is driven home, this jaw being driven to its final position after the anchor in engagement with the tie.

The wedging grip of the jaw 17 will ordinarily be sufficient to resist the normal creeping pressure of the rail. lt will be observed, however, that in addition to the wedge grip of jaw 1'1"' any pressure of the anchor against the tie tending to tilt the anchor, will increase the grip of the device by effecting a. shackle grip o the jaw 17 and the body of the anchor upon the top and bottom surfaces of the rail. lt will also be observed that when the anchor is applied to the rail with the angular aw 16 extending toward the tie, any tendency of the anchor to tilt under the creeping pressure of the rail will increase the torsional strain of the anchor and thereby increase the grip of jaw 16 on the rail.

lt will be seen from an inspection of the drawing that the jaw portion 16 of the anchor may be applied to either base flange of the rail. Then it is applied to the edge of flange 1;, the said jaw will extend longitudinally of the rail in a direct-ion away from the tic` Tffith such arrangement the tendency which the anchor has to return to the position from which it was twisted tends to ef feet ashackle grip of the jaw 17 and the body of the anchor upon the top and bottoni surfaces oil" the rail base. 1t will also be observed that, with the anchor applied in manner, any shackle grip of jaw 17, effooted by reason of the resiliency of the metal, will be increased under the influence of the creeping pressure of' the rail, and that auch increased grip will be effected without increasing the spring g i p of jaw 16.

lllhile I have described my invention in connectionV with one specific embodiment, it will be obvious that the features of construction may be varied without departure from my invention. lt will .therefore be understood that l contemplate all such modified constructions as come within the scope of the appended claims.
