To all whom it may concern:

Be it known that I, I'IARRY HICKS FERRIS, a citizen of the United States, residing at Anaheim, in the county of Orange and State of California, have invented certain new and useful improvements in Railroad Rail Anticreepcrs, of which the following is a specification, reference being had to the accompanying drawings.

This invention is .an improved anticreeper for use in connection with a tie plate to prevent the creeping of a railroad rail, the object of the invention being to provide an improved device otthis character which automatically engages and locks the rail against creeping and which may be readily disengaged from the rail to permitthe removal of the latter, the invention consisting in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanyin; drawings,l igure 1 is an end elevation 01 a tie plate provided with my improved anti-creeper, also showing the base portion of a rail, the latter heing indicated in section. Fig. is a plan of the same with a portion of the nase oi. the rail removed, Fig. 3 is a side elevation of the tie plate and anti-creeper. Fig. t is a detail perspective view showing a por-- tion of the tie plate, a portion of the base of a rail, and also showing the anti-creeper engaged with the rail base.

The tie plate 1, which in its general features is of well known construction, formed in its upper side with longitudinal channels 2, providing a longitudinal supporting iilange 3, between the channels and a pair of longitudinal planes t, at the outer sides of said channels, to coact with the flange S to support and form a seat for the base of a rail indicated at there being; also on one side of one of the planes l, a longitudinal shoulder or flange 5 which hairs against one side of the base of the rail. The tie plate is further provided. with openings (3 for the reception of the usual spikes which are en'lployed to secure the tie plate on the tie, and to also engage the base flanges of the rail and secure the 1- ll in place on the tie plate.

The tie plate is medially provided on the side opposite the flange or shoulder 5 with a boss 6, which forms a plane bearing surface, the tie plate being also provided at the bottom of which is level with and forms an extension of the plane uppe surface of the boss 6. This recess 7 extends slightly under and is partly overhung by one base flange of the rail as shown in'Fig. 1. The plate has'stnds 12 on its underside to on gage the tie. i

In accordance with my invention, I pro vide an anti-creeper or locking dog 8, whicl has a curved serrated surface 9, at its inner end, which is presented to one base ian j of the rail, and is pivotally mounted on to. boss 6, and on the bottom of the recess '7 by means oi arivet 10. The pivotal axis or"; the dog is eccentric to the circle of which the curved end 9 of the dog forms a segment, and the radius of the curved end 9, is great that while the central portion of the curved end of the dog will clear the lease flange of the rail when the axis or" the dog is exactly at right angles to the rail, movement or the dog in either direction will cause one side of its curved engaging end to impinge againstand firmly lock therailso to prevent the letter from creeping and also prevent the rail from rattling on the tie plate. That is to owing to the radius of the curved engag ing end of the dog, its iiorni in client, oppositely disposed wedge shapedwhich project beyond a circle drawn .fr the pivotal centerof the dog and touching the central port-ion of the engaging end thereoi". Hence when the dog is disposed with its axis at exactly right angles to the rail, its curved end is justont oft engag ment with the case of the rail the latter can he removed. By slightly turning the dog however, in either direction, its curved end will engage the rail and the cainming or wedge action of the dog against the side of the base of the rail will eliectually lock the rail in. place so thatit cannot or ep and that it cannot rattle.

The curved engaging end oi the anticreeper or loci-ting dog is also provided With a curved flange ll which projects outwardly therefrom. and hears under the engaged side of the base of the rail as indicated in Fig. 1, so that while the dog locks the rail in place on the tie plate, the base of the rail, one side thereof, also hears downwardly on the flange ll of the dog, and naterially assists in holding the dog in place andin eng'aged'posit-ion w'th respect to the rail,

inner side of the boss with a recess 7, the llhen it is desired to remove the rail for any purpose, itis only necessary to Strike the dog on one side and turn the dog to a position with its axis exactly at fight anglee to the rail.

5 v I claim In combination with a tie plate having a seat. for a rail, and a recess to extend under one side of the rail, a dog pivotally mounted on the bottom of said recess, hav- 10 ing a curved eamming end to bear against one 'base flange of the rail, and also having a flange at said camming end to engage under said base flange of the rail.

In testimony whereof I hereunto afiix my signature in the presence of two Witnesses. 15
