RAIL ANCHOR.

Application filed November 21, 1928-. Serial No. 320,952.

' This invention relates to improvements in rail anchors.

The primary object of this invention is the provision of an improved device for preventing the longitudinal creep of rails.

A further object of this invention is the provision of an improved rail anchor which is adapted to be effectively clamped upon a rail base and engaged upon a tie to prevent the longitudinal creep of the rail.

A further object of this invention is the provision of improved means for applying rail anchors to rails. p

A further object of this invention is the provision of an improved method for constructing rail anchors.

A Other objects and adavntages of this invention will be apparentduring the course of the following detailed description.

In the accompanying drawings, forming apart of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

F igure l is aplan view showing the improved rail anchor or antl-creep device with a tool for applying the same to a rail with respect to an. adjacent road bed tie; the tie 7 and; rail being shown in dotted lines.

Figure 2 is a vie-w showing the clamped relation of the rail anchor with respect to the rail and tie, which are shown in dotted lines.

Figures- 3 and 4 are transverse sectional views taken substantially on their respective lines in Figures l and 2 of the drawings.

Figure 5 is a fragmentary sldeelevation of a ra l and tie, showing a step by WlllCll the improved anchor is attached to the rail.

Figure 6 is a View showing the relation in which the anchor clamps upon a rail.

Figure 7 is a perspective viewshowing the improved rail anchor.

Figure 8 is a perspective view showing a tool for applying the rail anchor.

Figure 9 is a blank of flat stock steel. or other metal, showing the manner in which it is initially constructed prior to bending of the details thereof to form the rail anchor.

In the drawings, wherein for the purpose, of illustration is shown only a preferred embodiment of the invention, the letter A may generally designate ,the improved rail an- I chor, which is adapted to be applied upon the baseof'a rail B, and against a tie C,-t0 hold the'r'ail B- against longitudinal creeps thereof, said slots terminating short of the ends of the blank 19 opposite the ends upon whichthey respectively open. This divides the blank 19 into arm portions 22 and 23 along opposite sides thereof, and an intermediate cross or connecting portion 24. The blank 19 at the ends of the connecting portion 24 is bent upwardly on bending lines 25 and 26, to provide rail base edge engaging flanges 29 and 30, at opposite ends of the connect- .in sort-ion shown more )artieuiarlv in l Figure 7 of the-drawings; the flange 29 beingextended at right angles to the top surface of the connecting portion 24, and the flange 80 being relatively longer than the flange 29 and bent in an overhanging divergent relation with respect to the top surface of the connecting portion 24. The arm 23 is bent in a concavo-convex or segmental form in the plane of the intermediate portion 24,

and transverse thereto, and at its free end the arm 23 is bent slightly radially outward as at 30 and then upwardly to provide a lug or flange 31 which is adapted to be engaged against one side edge of the rail base in a relation to be subsequently described.

At the opposite side of the connecting por tion 24 of the rail anchor, the arm 22, shown in F igure 9, is bent to provide a straight por- 0 tion 34 divergent at an angle of less than 90 from the connecting portion 24, and lying in the same plane therewith; the arm 22 at the outer end of the portion 34 being turned to provide a downturned right angled portion 36, which is flattened and provides, in fact, a foot for engagement against a side ofthe tieC, to hold the anchor a ainst relative movement along the road be as Will be subsequently mentioned. It should be noted that the arm 23 is relatively long and is re silient, to provide a spring locking eflect of the rail anchor upon the rail in a relation to be subsequently mentioned.

Re i g to the'app icetien ofthe ra l anchor upon a rail, it is to be noted that the rail base engaging flanges 29 and 30, at opposite ends of the cross piece 24 have their rail base edge engaging surfaces spaced for a distance greater than the distance betweenv the side edges of the rail base. This enables the rail anchor to be placed upon the rail, beneath the base thereof, with the cross piece 21 extending transverse to the length of the rail, and with the flange hooked over one side margin of the rail base, as shown in Figure 3, and the other flange 29 engaging at the opposite side edge of the rail base. In this position the rail anchor may be slid longitudinally along the rail,'beneath the same, until the depending foot 36 engages against aside of the tie C, in the position shown in Figure 5 of the drawings. The cross piece 24: is then swung diagonally cross the rail base by pushing the flange end 29 towards, the tie C, until the position shown in Figure 1 is reached, and it will be noted that the locking arm 23 is then entirely positioned beneath the rail base. A special tool Dis then employed to flex the arm 23, against the normal spring action thereof, and bring the flanged end 31 thereof outwardly against the side edge of the rail base, to the position illustrated in Figure 2 of the drawings. This special tool D preferably consists of an elongated body 50, having one end 51 thereof flanged in right angled relation and bifurcated with a V-shaped recess 52. Spaced from the flange 51, and at the same side of the body 50 as flange 51 is a transverse extension 53 which has a finger 54 at the outer end thereof extending substantially parallel above thebody towards the end 51.

In operation, the lever D is fulcrumed at its end 51 upon a side edge of the rail base, with the'recess 52 straddling the said marsin of therail base, as shown in Figures 1 and 5 of the drawings, and thelinger 54: is hooked against the side of the rail anchor flange or lug 31, that is, with the flangeor lug 31 received in the socket provided by the extension'53, at a point spaced from the fulcrum end 51. The lever 50 then having a ful- 'cruin on the rail base is swung outward to flex the spring arm 2;) and bring the flange end 31 thereof outwardly and upwardly against and outer edge of the rail base, to the posi tion shown in Figure 2 of the drawings, and elsewhere. This places the spring arm 23 under tension, and locks the flanges 29 and 30 at opposite ends of the rail anchor cross piece 245, against the opposite sides of the rail base flanges,-biting into the same, as shown is Figure 20f the drawings. :Inasmuch as the tie.

engaging foot 36 is disposed to one side of the longltudinal med al line of the rail, it is apparent that any tendency of the rail to creep over the tie G will cause the rail anchor at i the flanges 29 and 30 to bite more effectively into the rail base flanges, and preventing longitudinal creep of the rail overthe tie 0.

Various changes in the shape, size, and arrangement of parts may belinade in the form of invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.

I claim:
