EDGAR M. SMITH, or new YORK, N.

ANTICREEPING DEVICE FOR RAILS.
Specification of Letters Patent.
Patented Feb. 14, 1911.
Application filed March 18, 1910. Serial No. 550,098.
-York and State of New York, have invented certain new and useful Improvements in Anticreeping Devices for Rails; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.
The object of this invention is to provide an improved, simple and highly eflicient anti-creeper for railway rails which will increase its hold on a rail as the latter slides or creeps in one direction.
The invention will be hereinafter fully set forth and particularly pointed out in the claims. 7
In the accompanying drawings, Figure l is an elevation. Fig. 2 isa plan view, and Fig. 3 is a view in perspective.
In carrying out my present invention the device is composed of two cooperating clamping members, the member 1 having at one end an upturned lip 2 forengaging the base of a rail at one side thereof, while the other member 3 has a cam-surface 4: for engaging the edge of the rail base at the other side thereof, and a flange 5 for overhanging such edge. The two members are united in such manner that as the wedging action of cam 4 on the rail base is increased the hold of lip 2 of the other member will be correspondingly increased. For the purpose of bringing about this result, and avoiding the use of small separate parts which are liable to become displaced, I form a tongue and groove connection between the two parts, a groove 6 being formed in the upper face of part 1 and a tongue 7 on the undersideof part 3, and in this tongue I also form a groove 8 to receive a lip 9 of part 1 so as to thereby avoid all danger of the parts being separated. The groove 6 and tongue 7 are concentric, and the radius of the are thereof is considerably greater than that of cam t, and is struck from a different center, being at the longitudinal center of member 3.
The clamping member 3 is'provided with a suitably braced curved arm lOfiwhich is located at one side of the clamp. This arm is designed to contact with an adjacent rail sleeper. consequent upon creeping of the ra l. When this occurs clamping member 1 wlll be caused to move relatively to clamping member 3, in the direction of arrow Y, Fig. 2, and by reason of the wedging action of cam 4 on one side of the rail base and the concentric connection between the two clamping members, the hold of member 3 will be increased, thus making the grip on the rail tighter, the extent thereof being dependent upon the force of the pressure against arm 10.
It will be seen that the increased grip of the clamp is brought about by the creeping of a rail, and this results in the curved arm being pressed against the sleeper which, in turn, is held by the ballast. In proportion as the rail creeps the hold of the device on the rail is increased.
I claim as my invention: Q
1. An anti-creeper for rails comprising two clamping members, one engaging one side of a rail base, and the other having a cam to engage the other side of the rail base, and an arm for engaging a rail-sleeper, said clamping members being united by concentric engaging portions.
2. An anti creeper for rails comprising two clamping members, one engaging one side of a rail, base, and the other having a camfor engaging the other side of the rail base, and also having an arm at one side thereof for engaging a rail-sleeper, and a concentric tongue-and-groove connection be tween said members.
An anti-creeper for rails comprising the other having a cam to engage the other side of the rail base, a flange projecting over- 'second'memberi foi' engaging a rail-sleeper, ing Witnesses.
such base, a curved arm at one side of said specification in the presence oftwo subscriband a. curved iiongue-and-gi'oove connection between the two members, said groove having a lip and said tongue a groove to receive said lip.
In testimony whereof, I have signed this EDGAR M. SMITH.
Witnesses:
ROBERT S. ANDERSON, THOMAS J. LUNELL.
