ALPHONSO T. PALMER, OF CHICAGO, ILLINOIS.

BAIL ANTIGREEPER.

Application filed April 27, 1925. Serial No. 26,185.

My invention relates to rail anchoring de-.

vices for railway rails and has for one of its objects the provision of simple and oliicient means for effectively holding rails, and the like, from longitudinal movement A further object of my invention is the provision of a clamping device having a lever, wedge, and torque action produced by one and the same adjustable tightening means. y

Another object of my invention is the provision of a rail anchoring device that is adapted to hold therail plate in its proper position. y

A still further object of my invention is the provision of means for anchoring a rail in placethat are adapted to be effective in restraining the backward thrust of the. rail as well as the forward thrust thereof.

Another object of my invention is the provision of the device which can be easily applied to a rail with comparatively little cost in labor.

A furtherobject of my invention is the provision of a rail anchoring device that may be tightened periodically to compensate for the elasticity and wear of the parts thereof.

Other objects will appear hereinafter the novel features and combinations being clearly set forth in the appendedclairns.

In the drawings: p l

Fig. 1. is a horizontal plan View ofa fragmental sectionof the tie and rail showing my improved anchoring device secured thereto;

Fig. 2 is a fragmental sectional view taken on line 2--2 and looking in the direction of the arrow;

Fig. 3 is a side elevationof arail showing my improved rail anti-creeper; I

Fig. 4 is a cross-sectional view taken on line 4l-t of Fig. 3 and looking in the direc: tion of the arrows; and H I Fig. 5 is a fragmental sectional view showing an exaggerated illustration of the relative tightened positions of several elements of the anchoring device.

Referring more particularly. to the drawings it will beseen in Fig. l that the anchoring device comprises a metal gripping member 1, preferably of cast iron havinga flat outer side 2 and an inner side having a groove 3 extending longitudinally of its length. The groove 3 is provided to receive the edge portions of the flange ofa rail This groove'3 has a. flat lower surface 6 and an inclined upper wall 7, the upper wall 7 being inclined sufliciently to the parallel with the inclined upper surface. of the flange of the rail The groove 3 is of such size as to provide a tight wedging grip on the edge portion 4 of the flange when the metal member is secured thereon.

In Figs. 1, 2 andS the anchoring device is shown secured to the rail 5 which is mounted on a tie 8, there being a rail plate 9 dis posedbetween the rail and tie. The metal side member 1 is disclosed as being substantially longer than it is wide and provided with a flange 10 through whichan opening 11 passes. This opening is rectangular in cross-section as shown in Fig. 1 and is for; the purpose of receiving arail spike 12. The flange 10 is located adjacent the inner end of the side member 1 and the opening 11 therein is in registration with an opening 13 in the rail plate 9. The spike 12 passes through both of'these openings and into the tie 8,.thus securing the flange-engaging side memberl, the rail plate 9 and the tie Sin a fixed relation. The outer end orthe end of the flange-engaging member which is spaced apart from the tie, is disclosed as being enlarged and having an openingtherethrough to receive a hook b olt le sh0ulder 15 is provided on the grooved gripping member 1 at the point where the enlargement commences. This shoulder abuts against the edge 16 of the rail plate 9 for reasons hereinafter disclosed.

The hoolr-bolt 14 is shown .in Figs. 1 and 41- to be disposed beneath the rail flange and adjacent the lowermost surface 17 thereof. This bolt is threaded at one end to receive a nut 18 and is enlarged and disposed upwardly at the opposite end to form a book 19. 'The hoolr 19 is formed to receive the lateral edge 21 of a flange of the rail 5 and is prolonged to extend slightly over the inclined upper surface 21 of the flange. It should be understood that the hook-bolt 14 lies adjacent the bottom surface 17 of the rail 5 and that said hook is slightly spaced apart from the lateral side 22 of the tie 8. This hook-bolt 14 is positioned in the space between the bottom surface of the rail and the bed of the roadupon which the tie rests. When the bolt 14 is positioned as shown in the drawlugs and. the nut 18 is tightened the flange edge engaging member l is tightly wedged. upon the edge portion 4: of the flange; When the nut 18 has been tightened sufliciently to force the flange edge portion 4 completely within the groove 3, further tightening of the nut produces a leverage which tends to cause the flange edge-engaging member 1 to assume the position shown in Fig. 5, it being understood that the hook-bolt lispositioned below the groove Ssufliciently to produce such a leverage action. This leverage action tends to pull downwardly onthe two lateral flange edge portions i and 20 and to. move the central portion of the bottom of the rail upwardly. Thus it should be understood that the anchoring device is clamped and secured tightly to the rail flange by means of a plurality of forces namely the direct wedging action of the edge portion l of the flange within the groove 3, thelevere age due to the position of the hook-bolt I l with respect to the groovefiand the stress caused by such aleverage action which tends to drawthe edge portions of the flange downwardly. It should be understood that the leverage action causes the edge portion 4 of the flange to be gripped by the upper and lowerywalls 7 and 6 respectively of the groove 3 with a force additional to the force caused by the wedging action.

All of the forces applied by the hook-bolt are forthe purpose of clamping the anchoring device securely to the edge portion of the flange of a rail. With the device secured to the rail as illustrated and described the rail is restrained from longitudinal. movement relative to the tie by means of the spike 12 and the shoulderlo, It is again pointed out that the shoulder 15 abuts against the edge 16" of theplate 9. The rail plate 9 is secured to the tie by the spike 12 and by an additional spike 23 positioned diametrically opposite from the spike12. For this reason any movement of the rail to thefleft as viewed inFig. 3 is arrested by the shoulder 15 which abuts against the edge of the rigidly secured rail plate 9. Movement of the rail in both directions is also'arrested by thespike 12 which passes through the flange 10 ofthe gripping member 1 and through the rail plate 9. t

I lVhen a train passes over the rails the latter tend to move in the direction of the train. This movement is called the forward movement of the railand is due to vertical waving ofthe latter in advance of the train.

Backward movement of therail is also pr0 duced by the thrust of the wheels in the direction opposite to the-direction ofjinove-' ment of the train. Both of these movements are effectively arrested by the anti-creeping device herein disclosed; The forward moveinentis by far the greater andis resisted by V the spike 12 which secures the gripping member 1 directly to the tie and by the rail plate which is secured directly to the tie by spikes 12 and"23 and which ahuts against the shoulder'15 of the gripping memberl.

Obviously those skilled in the art may make various changes in the details and arrangement of the parts without departing from the spirit and scope oi. the invention defined by the claims hereto appended, and it is therefore desired not to be restricted to the precise construction herein disclosed.

l-laving thus fully described and shown an embodiment of: the invention what is desired to be secured by Letters Patent of the United States is: i
