ANTICREEPER.

Application filed December 1, 1923. Serial no. 677,995.

county of Richmond and State of New York,

have invented new and useful Improvements in Anticreepers, of which the following is a specification. Y

T his invention relates to anti-creepers for use in connection with railroad rails.

The principal object of the invention is the provision of a device for attachemnt to the base of a rail and for co -action with the supporting ties to prevent undue creeping of the rail usually caused by the traveling of rolling stock in one direction.

Another object of the invention is to PTO: vide, an anti-creeper which will prevent creeping of the rails, but will allow for ex pansion and contraction of the rail due to climatic conditions.

A further object of the invention is to provide an anti-creeping device which may be quickly applied or removed from the rail without the use of fastening elements.

.31 still further object of the invention is to provide a device which is simple in construction, cheap of manufacture and highly efficient for the purpose intended.

WVith these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which v Figure 1 is a side elevation of my invention showing the same in use.

Figure 2 is a bottom plan view of the same with parts broken away in section.

Figure 3 is a transverse sectional View on the line %2 of Figure 1.

Figure 4 is a perspective View of my inven tion per se.

In all rails, it is the tendency for them to creep in the direction of travel of the rolling stock, and it is therefore my intention to construct a device for attachment to the rail which will overcome this objection;

Referring more particularly to the drawing, the reference numeral 10 designates a portion of a rail and 11 the supporting ties therefor. My invention is shown in its entirety at 12 and is cast in a single piece to form a pair of rail engaging members 13 and 14.- A portion 15 connects the

rail engaging members

13 and 14, and'is adapted to'underlie the base of the rail when the device in position as clearly the drawing.

13 and extending an arm16- which has its end terminating in a foot 17. The arm 16 is formed witli ja Depending from member socket 18 for the reception, of a spring ie,

one end of which is secured to th efeiidTwall of the socket and the other end of which is adapted to co-act with one side of the tie to retain the device in operative position upon expansion or contraction of the rail.

The

rail engaging members

13 and 14 are similar in construction with the exception that the member 13 is slightl larger than the member 14. Each of the anges is provided with an arcuate outwardly extending inner wall 20, therwall being provided with teethor serrations 21 for engagement with the edges of the rail base. The overhangin portions of the members are also providec with serrations 22for engagement with the top of the rail base, and the portion underlying the overhanging portion is likewise serrated as at 23 for engagement with the bottom of the rail base.

In applying the device to a rail, the same is brought up under the base of the rail with shown in Figures-2 and 3' horizontally therefrom is i the portion 15 substantially at right angle to the longitudinal axis of the rail so that the overhanging portions ofthe

members

13 and 14 will clear the edge of the base, after which the device is given a slight turnand moved against the tie to compress the spring 19 in order to put'the device under tension so as to bring the teeth 21 of each memberin engagement with the edge of the co-acting base. It will be seen that the spring sets up a binding action between the teeth 21 and the rail and'that any tendency of the rail to creep in the direction of the arrow shown in Figure 1 will cause the foot 17 to coact with the tie and prevent further movement and if for any reason the rail should creep in the opposite direction the engagement of the spring with the tie will prevent casual displacement of the device, as will be readily apparent. Serrations or co -act with the rail base for holding the deteeth 22 and 23also' vice in engagement therewith. It will also be seen that the rail may expand or contract in either direction according to climatic conditions without in any way effecting the principle of the device.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

What is claimed as new is 1. In combination with a rail, supporting ties therefor, an anti-creeping device including rail engaging elements and having an cuate shaped \yalls provided with serrations, a downwardly extending portion formed on one of said members, a foot formed on the end of said portion, and a coil spring carried by said portion for co-action with the tie for thepurpose specified for forcing said serrations into binding engagement with the base of the rail. 7

2. In combination with a rail, supporting ties therefor, an anti-creeping device removably carried by the base of said rail, yieldable means on said device and means carrying the yieldable means for engagement With said tie upon movement of the rail in one direction.

3. The combination with a rail, supporting ties therefor, of an anti-creeping device for said rails comprising a pair of spaced rail engaging members adapted to re ceive the opposite side edges of the base flange of the rails, spaced arcuate shaped gripping flanges formed on each member, serrations formed on the Walls of each flange, an arm extending at right angles from adja cent one member and being provided with a bore, a foot formed on the free end of the arm and a coil spring fixed Within the bore for the purpose specified.

In testimony whereof I have afiiXed my signature.
