JOHN R. CALDERON, OF CHICAGO, ILLINOIS, ASSIGNOB, TO ILLINOIS MALLEABLE IRO-Nv CO., OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

DEVICE FOR PREVENTING THE CREPING OF RAILS.

Application led August 23, 1923. Serial No. 658,863.

To vall 'whom it 'may concern.'

Be it known that I, JOHN R. CALDERON, a citizen of the United States, residing at Chicago, in the county of Cook and Sta-te of Illinois, have invented certain new and useful Improvements in Devices for Preventing the Creepin of Rails, of which-the following is a specication.

Thel present invention relates to improvements in devices for preventing the creeping of rails.

Many devices are known and are being used in connection with railroad rails for preventing the longitudinal creeping thereof. As now known and used, such devices are open to criticism for various reasons, among which may be noted the fact that they afford only a very poor holding effect upon the rail and the fact that they are hard to reach for attachment and adjustment.

An object of the present invention is to provide holding means for iirmly gripping a railroad rail.

A further object is to provide means for preventing creeping of a railroad rail, which means is simple to attach and adjust.

A further object is to provide ancanticreeper which may be readily attached to a railroad rail and by utilizing the resilience of the metal of said rail provide a tight grip upon said rail.

A further object is to provide an anticreeper which combines the advantages of a tight grip on a railroad rail, readiness of applicability and adjustment, sturdiness, and cheapness of manufacture.

A further object is to provide an anti-v creeper which combines the advantagesl of readiness of applicabilitywith nut locking features whereby there is little danger of the anti-creeper becomingloose in service.

A further object is to provide an anticreeper which serves to firmly grip a rail with a leverage action and by the same leverage action performs nut locking functions.

Further objects will yappear as the description proceeds.

Referring to the drawingsl y Figure 1 is a view of one embodiment of the present invention applied to a railroad rail, said rail being shown in section;

Figure 2 is another view of the embodiment of the presentv invention illustrated in n nut locking features above referred to.

Referring first to Figures 1 and 2, the members 1 and 2 are complementary members having the hooked over 'end portions 3 andt respectively. The hooked over end portions -3 and l are adapted to hook over the opposite' flanges 5 5 of the rail'6. The members 1 and 2'may be composed of malleable iron, steel, or other tough material capable of withstanding the shocks encoun-v tered inrailroad service. The member l is provided with the downwardly extendingl portion 7, which provides a seat 8 for the head 9 of a bolt 10. 'Said bolt 10 normally occupies a position inclined to the horizontaland to the vertical, ,for *whichA reasonl the seat 8 should be arranged in a corresponding angular position. The wardly extending portion 7 is provided with a slot 11 for the reception of thebolt 10, said slot being bounded longitudinally of the railroad rail by, the undercut shoulders 12-12the undercut portionsof which form the seat The member 2 is` provided with the outstanding portion 13,' which is provided v with a hole for the reception of the bolt 10. Any preferred means, such as the lock washer 1 4 and nut 15, may be provided for holding they bolt 10 and consequently holding the `members 1 and 2 in gripping relation to the railroad rail. For the purpose of providing a strong leverage action, the members 1 and 2 are formed to provide portions adapted toengage the under side of the rail at lines 15-15 relatively distant from the side edges of the flanges ofV down- 16-16 is ad-apted to abut against lthe cross j tie 17 .j By reason of the fact that the members 1 and 2 have gripping engagement with the anges of the rail, and by reason of the fact that the bolt 10 exerts a leverage action on each of the members 1 and 2 about the lines 15-15, the net effect is a very firm gripping engagement between the flanges of the rail 6 on the one hand and the members 1 and 2 on the other hand. By reason of the fact that the members y1 and 2 contact with the bottom of the rail at 'lines spaced materially from the edges thereof, said members 1 and 2 are drawn into such tight engagement with the rail that slippage is effectually prevented. The angular position of the bolt 10 accomplishes the further advantage that a workman may effectually tighten saidrbolt in an expeditious manner. In practice a workman may proceed along the track with a socket` wrench and turn downl the nuts on a succession of the bolts 10, working rapidly and with assurance that a non-slipping engagement with the rail will be accomplished. By reason of the engagement of the side face 16 with a railroad tie, the structure illustrated in Figures 1 and 2 will prevent creepage in one direction of traiiic, that is tol say-to the right as viewed in Figure 2.

The construction illustrated in Figures 3 and 4 is designed particularly for rails in which traiiic is likely to occur in both directions. The construction shown in Figures 3 and 4 is similar to that shown 'in Figures 1 and 2 in most respects. According to the structure shown in Figures 3 and 4, the member 1 has integral therewith a bed. plate 18. Said bed plate 18 extends from one of the sides 16 ot said member 1 in a direction longitudinally of the railroad rail and is provided with a pair of shoulders 19-19 spaced apart a distance to receive the base of the rail 6. Said bed plate is provided with spike holes 20-20 for the reception of the spikes 21-21, the heads of said spikes 21-21 being adapted to overlie the flanges 5-5 of the rail 6. Said spikes also serve to prevent movement of the anchor plate 18 longitudinally of the rail.

It will be clear that the construction shown in Figures 3 and 4 provides a practical struct-ure for preventing creeping ot the rails in either direction longitudinally of said rails. rlhe members 1 and 2 cooperate in the manner discussed in connection with Figures 1 and 2 to form a tight grip on the rail whereby slippage of the saine is prevented. Movement oi the member 1 and consequently of the rail is prevented by reason of the spikes 21--21 which engage the ties 17.

Referring now to Figures 5 and 6, itwill be apparent that the present inventionadapts itself readily to nut locking features. As will be clear from an inspection of Figures 5 and 6, the outstanding portion 13 is position the bolt 10 will have been bent materially at its threaded portion. The threads on the concave side ofV the bent bolt 10 will be compressed and the threads on the convex side of the bent bolt l() will be spread. By reason of this action the nut 15 will be eifectually prevented from backing oil'7 though said nut may be removed by a workman provided with a proper tool.

The lock washer 14 may or may vnot be Y used, as'desired, in the construction shown in Figures 5 and 6. It will be clear that the nut locking features shown in Figures 5` and 6 are applicable tothe structures shown in Figures 1 to 4.

Though certain practical embodiments of the invention have been illustrated, it will be clear that many modiiications are possible and will occur to those skilled in the art. It is intended in this patent to cover all such modications which fall within the scope of the invention as defined by the Vappended claims.
