RAIL ANCHOR. 7

Application filed January 13. 1926., Serial No. 80,981.

My invention relates to rail anchoring de A more specific object is topro'vide an improved one-piece rail anchor formed with jaw portions adapted to grip the top and bottom surfaces of a rail base at one side of the rail and formed with n'leans for engaging the top and vertical surfaces of said base flange at the other side of the rail to lock the anchor in its applied position.

Another object is to provide a one-piece device which may be conveniently i'nade from a flat metal plate recessed to provide the rail-gripping jaw portions of the'devicc, the said jaws being so disposed with relation to each other as to provide in etfect a rcla-,

tively wide bearing surface with respect to the thickness of the plate from which the device is made. i

The invention has for further objects the provision of such other new and improved features of construction and arrang en'ient of parts as will be hereinafter described and claimed for carrying out the above stated objects and such other objects as will appear from the following description of a preferred embodiment of the invention.

A preferred embodiment of the invention is illustrated in the accompanying drawing, wherein Fig. 1 is a plan view of the base portion of a railroad rail showing a rail anchoring device, constructed in accordan'cewith my invention, applied thereto.

Fig. 2 is a side elevation of the rail anchor device, the base portion of the railroad rail being shown in section.

Fig. 3 is an end view of the device shown in Fig. 2, the said view being taken from the left of Fig. 2, and

Fig. 4 is a view in perspective of the rail anchor device shown in thepreceding figures.

In the drawing, the numeral 10 designates the base portion of a railroad rail and the numeral 11 designates one of the cross ties on which the rail is supported.

The embodiment of the invention shown rail.

inthe drawing consists of a rail base embracing yoke cut from a steel plate and bent to the configuration shown in the drawing. The yoke consists of a body portion 12 which extends across beneath the rail base and is formed with hook shaped jaw portions 13 and 1 1. The jaw portion 13 comprises a relatively long arm 15 bent to a U-shaped configuration to provide spaced jaws 13 13 The arm 15 is formed from the ma terial of the blank which is ordinarily cut away to provide the recess for the base of the However, in thisembodiment, the arm 15 is made. relatively long, as shown in dottedlines in Fig. l, and is bent outwardly toward the'end of the yoke to form said U-shaped configuration. *The lower edges of the spaced jaws are tapered to correspond with the inclination of the rail base so as to bear fiat against said inclined top surface of the rail base when the anchor'is applied thereto. The free end of the jaw portion 13? is formed with a depending shoulder 16 adapted to snap into engagement with the vertical surface 17 of the rail base when the anchor-is forced to its applied position on when the anchor is moved from the dotted line position of Fig. 2 to the full line position. The upper edge of the body portion at the jaw end 14 of the anchor bears against the bottom surface of the rail base to substantially the middle of said base, at which point it inclines downwardly with respect to the rail base, as shown at 19, so that a portion of the recess 18 underlying the spaced jaws will be somewhat wider than the thickness of the rail base. This construction permits the spaced jaws to be readily hooked over one base flange of the rail,

and providesa pivot point' 20, about which the anchor rocks when it is applied.

In order to provide the necessary clearance to permit the jaw 14 to clear the opposite edge of the rail base, the recess is made somewhat longer than the width of the base flange of the rail, whereby the anity of this jaw may be effected by bending it from either side of the body. In the drawing, the said jaw is bent outwardly from the body in the same general direction as the long arm 15, whereby a line parallel with the body passing through the end of the jaw 14; will pass between the said spaced jaws l3 and 13" at. the opposite side of the rail.

In applying theranchor to a rail, the spaced jaws 1313 first hooked over one flange of therail base so that shoulder 16 will engage the upper surface of the rail base, substantially as shown in Fig. 2 of the drawing. lVith' the anchor in this prelimi nary posit-ion, the end of jaw 14- will clear the opposite edge of the rail base and the apex '20 of the angle formed by the edges 19 and 21 of the body will be a short distance to the left of the center of the rail base, as viewed in Fig. 2. The anchor is then driven transversely of the rail to force the aw 14: upon the inclined upper surface of the rail base. This movement of the jaw 14 upon the rail rocks the anchor about the pivot point 20. This rocking movement is permitted without subjecting the anchor to.

any substantial stress by reason of the fact that the pivot point 20 is substantially midway between the jaws at opposite ends of the anchor. Under such condition, the spaced jaws 13 3 move down the in clined surt'ace of the rail base the same vertical distance that the jaw i l moves upardly on the inclined surface of the flange at the opposite side of the rail. There is, however, some preliminary tension effected by reason of the engagement of the shoulder 16 with the top surface of the rail'base. The degree of this preliminary tension is determined by the length of the shoulder 16 and may be partially or entirely relieved when the shoulder snaps down over the edge of the rail base to lock the anchor in its applied position. Preierably, the said shoulder is of such length that a slight tension remains in the jaw 13 after the anchor has been driven home. The main grip of the ant-hon however, is obtained by reason of the wcdeing engagen'ient of the jaw 14- and the surface of the body with the upper and lower surfaces. respectively, of the rail base.

In the drawing I have shown a structure that is particularly suitable to be made of metal of low grade. since any substantial spring tension is not essential to the proper operation of the device. dowever, it will be apparent that in situations in which it may be desirable to use a higher grade metal having more resiliency, advantage or such resiliency can be obtained by shifting the pivot 20 toward the jaw 14 or by increasing the angularity of jaw 1-2 with respect to the upper inclined surface of the rail base so as to provide a differential arrangement of parts which will effect an increasing spring grip as the anchor is driven home. It will also be seen that the preliminary spring grip of the anchor may be increased by decreasing the vertical distance between the bearing surfaces of the jaws BB -l3 and the horizontal edge 21 of the anchor body. By such construction the anchor may be subjected to greater distortion than will be re lieved by themovement of the jaws 13 13" downwardly on the inclined surface of the rail base. i 1

lVhile I have described my invention in connection with one specific embodiment it will be obvious that modifications in structure may be made without departure from the spirit or my invention. 1, therefore, wish it understood that I contemplate all variations in structure that come within the scope of the appended claims.
