RAIL ANTICREEPER.

Application filed July 29, 1925. Serial No. 46,701.

My invention relates to anti-creeping de vices for rail-way rails. and the like, and has for one of its objects the provision of simple and effective means for efficiently and effectively holding railway rails, and the like, from longitudinal movement.

A further object of my invention is the provision of a device of the character mentioned which will not be detached by movementof the rail in frozen ground.

A still further object of my inventionis the provision of a device of the character mentioned which can be easily and quickly attached to a railway track.

Another object of my invention is the provisionof an anti-creeper comprising a single unitary member.

A further object of my invention is the provision of a device of the character men- T tioned that is adapted to dig into a rail when the latter tends to move longitudinally relative to a tie to which it is spiked.

In the drawings:

Fig. 1 is a top plan view of a railway rail,

tie. tie plate and anti-creeping device embodying my invention;

Fig. 2 is a side elevational view of the device disclosed in Fig. l'showing a sectional view of a railway rail; and

Fig. 3 is an end view of the parts shown in Fig. 1.

Referring more particularly to the drawings, I have indicated in Fig. 1 a fragment of a railway tie 4 of any desired construction. 011 the tie 4 is indicated the bottom portion of the rail 5 having the usual flanges member 6. The member 6 may be of a stiff spring metal or of any desired material. It

4 is preferable that it have suflicient stifi'ness and size to afford strength to hold the anticreeping parts against the rail. flanges to prevent movement thereof along the rail.

The member 6 has its central portion curved as shown at 7 in Figs. 1 and 8 so that the curved intermediate portion 7 protrudes outwardly away fromthe side 8 of the tie 4. The end portions9 and 10 of the spring plate 6 are substantially flat and the curvature of the spring plate exists between these end portions.

The edge 11 of the curved portion of the spring plate 6 is disposed below the flanges 5' and the flat end portions 9 and 10 extend above such flanges. The flat end portion 9 Disposed under the rail 5 is a resilient is provided with a hook 12 which is adapted to engage one of the flangesfti'. A hook13 is provided on the flat end portion 10 of the spring plate'6. It will be seen in Figs. 1 and 2 that the hooks 12 and 13 extend over the upper surface of the flanges 5 and that the hook 12 islonger than the hook 13 for reasons hereinafter disclosed.

The spring plate 6 is provided with an outwardly directed bulge located at the center of the curved portion 7. It will be seen in Fig. 1 that the outwardly bulged portion 14 has its center of curvature on the same side of the spring plate 6 as is the center of curvature of the curved portion 7. In other words. both the curved portion 7 and the bulged portion 14 are directediaway from the side 8 of the tie 4. .The bulged portion 14 is substantially spoon-shaped in form and is longer than it is wide. An indentation on the concave side'of the curved portion 7 results from the formation of the bulge 14 and this indentation tends to draw or pull the ends of the spring metal plate together. The curvature 7 and the bulge 14 both co-operate in producing a spring action in the plate 6 that tends to impel the end portions of such plate towards each other. A slight extension 15 is provided on the edge 11 of the curved portion 7. This extension extends an equal distance on each side of the center line of the spring metal plate 6 and is providedwith a sharp knife edge 16. The knife edge '16 is shown in Fig. 3 to have a vertical side 17 and a bevelled side 18. The bevelled side 18 extends from the upper edge 11 of the curved portion 7 to the knife edge16. This knife edge has the same curvature as the curvature of the portion? of the metal plated When the anti-creeping device is secured to the rail flanges 5' it is positioned as shown in the dotted lines at 19 with the large hook 12 of the flatportion 9 disposed over one flange 5"of the rail. A tool such as shown in'Fig. 2 having a bent lower end 23 and a handle 24 may be employed by inserting the bent end in theopening 25 for the purpose of expanding the spring metal. plate 6. The intermediate portion'of the handle may be rested against the edge 20 of the left hand flange 5 while a force isapplied on the upper end of suchhandle to move the latter in the direction of the rail. This action will'result in a temporary reduction of the curvature of the plate and may be continued until the? plate has been extended sufiiciently to permit the hook member 13 to be disposed over the edge 20 of the left hand flange 5. Use of thetool may then be discontinued so as to permit the tension in the spring plate 6 to force the hook over the upper surface of the left hand flange 5'. firmly gripped in the slots 21 and 22 beneath the hooks 12 and respectively. all of the forces applied on the edge portions of the rail being supplied by the'bulged' and curved portion ofthe spring metal plate.

It will be seen in Fig. 3 that the knife edge 16 isat a l iighe'r elevationthan the edge 11 of the curved portion 7. As a result of the length of the extension 15 the anti-creeping device is caused to" assume the position shown in Fig; 3 with the lowermost portion of the flat sides engaging theside 8 of the tie 45. Thus.- when the rail tends to move lon'giitudinal liv' relative to the tie 4 it also tends to carry the anti-creeping device which is firmly cliaanped on the flange thereof along with it. The slightest movement of the rail causes the bottom portion of the flat ends 9' and 10 to press against the side 8' of thetie- 4' thus" restrainingsuch movement. The pressure against the SlClQ of the tie causes the plate to: act as a lever to force. the edge 16 against the under face of the rail and to bite'i nto the rail to prevent the rail from slipping.v

The movement of the rail is restrained in the above mentioned ways,- and the great power of the anchoring device is the result of the leverage action it exerts when the rail tends-to move. Even: the slightest movement of the raiL would cause the spring metal plate 6 to tend to turn about the knife edge" 16' as a fulcrum. This tendency of the spring metal plate 6 causes the knife edge to bite into the rail and: the hook members 12- and 13- to be drawn down: firmly upon the upper surface of flanges 5" and results in such flanges being gripped with a tremendous force. In: other words the spring pliartemember 6 is adapted to grip the flanges of a rail with sufficient force to prevent the: movement of the rail relative to the spring plate to resist the slighest movemen-t and the leverage action is adapted to increase the gripping power of the chisel edge 19 and the hooks 12 and" 18- upon theflanges for the purpose of resisting additional} movement.

Obviously those skilled in the art may make various changes in: detail and arrangement of parts without departing from the spirit and scopeof the invention defined by the claims hereto appended. and it is therefore desired not to-be restricted to the precise construction hereindisclosed Having thus fully described and shown an The edge portions 20 are then I embodiment of the invention, what is desired to be secured by Letters Patent of the United States is:
