L. 0. HENGGL' ANTICREEPER. APPLICATION {ILED NOV-Z1, 191a.

Patenfed Apr. 15, 1919 to the rail base a is similarto the applica-' 4 its end engages with the top of saidrail base and the anti creeper A then drawn i i;

upwardly until the seat 8 of the anti:

f. creeper engages the bottom of the rail base a as shown in Fig. 5. lt'will be seen from this figure that it will lie' impossible 'i the rail base nearest the same.

to move the jaw 3 onto theiai pper side of tion of the seat 8 bearingfagainst the rail base. This operation is completed by driving the anti-creeper transverse oiithe rail base by means of a sledge hammer or- -.the like applied to the outer surface B of the anti-creeper, whereupon-the curved portions 12 and 13 will have their inner surfaces 7 and 6 respectively bearing upon the upper faces of the rail base a with the interme diate portion 11 bearing against the bottom of said rail base, and the shoulder or projection 14 will drop over and bear against the outer edge of the rail base to further prevent its becoming loose or displaced. During the application ofthe anti-creeper A to the rail base a and its passage fr m the position'shown in Fig, 5 to th t,,sho, i n in Fig.6, the seat 8 hasibeen gradually displaced downwardly and when the -lfinal position is reached, sufiicient spring action is exertedby said seat against the bottom of the rail base a, together with the action of the inner surfaceso and 7 on the upper portion of the rail, to firmly and securely bind the same in position, In fact, the tendency of the intermediate portion 11 to re:

turn to its original shape results in an extremely strong gripping action 01 the rail base and such action is much more than sufficient to hold the anti-creeper in position regardless of any vibration to which the rail is subjected, or in spite orother influences.

The anti-creeper A is so placed that its one'side' :0 will abut against a tieand at that side of the tie opposite to the direction in which there is a tendency for the. rail to creep. The anti-creeper by its gripping action thus prevents any longitudinal moveof weather changes 7 4 ment of the rail across the tie.

Figs. 7 and 8 show a modification wherein the, anti-creeper A is constru'ted pre -cise1y the same as that shown in the otherfigures of the drawing, except that the seat 8 in Fig 1 is-eliminatcd and a bearingsurface 15 made to conform with'the taper of the key 16, which is driven between said bearing surface and the bottom 'of the rail base a. placed upon the rail with the inner "faces- 6 and? bearing upon the rail. base Ml-and the shoulder or projection ll bearing against This form of anti-creeper is ithout distormomma one side of the rail flange whereupon. he

key 16 is driven between said suriace in will be pressedor driven over in order that "jitfmay pass into the opening of the jaw 2 gm will engage the outer edge of the metal arming the open portion a and thus prevent its removal by vibration or other influence It will be readily seen that the driving actionagainst the end 17 of the'lrey 3.6 will distort the intermediate portion 11 of the anti-creeper precisely in the manner that the seat 8 of such portion will be deflected by the driving action against the side B of the anti-creeper A shown inFigbo, and thus the key 16 bearing against the bottom, and the inner surfaces 1 and 6 of the curved portions 12 and 13 ofthejaws 3 and 2 will grip the rail base a and hold it in the same manner 'as above described,

The anti-creeper as shown and described is extremely simple and easy of manufacture applied to the rail the anti-creeper will not i become loose, nor will it shift longitudinally onthe railbase, as the gripping action is many times greater than the amount ,nec-

essary to overcome any vibrations, changes in atmospheric conditions, etc.

What I claim as my invention and deslre to secure by Letters Patentis 1. An anti-creeper for rails comprising a plate having an intermediate flared-out bearing portion for engaging withthe bottom of the rail base, and terminal gripping jaws formed onthe plate for securing said anticreeper to the rail base, said anti-creeper being adapted to be moved transversely on the rail base, whereby the jaws may be tightened on said-rail base;

2. An anti-creeper for rails comprising a plate having an intermediate flared-out bear ing portion for engaging with the bottom oi the rail base, and terminal gripping jaws having increased curved bearing faces formedon the plate for securing saidanticreeper to the rail base, said anti-creeper'. beingadapted to be moved transversely on the rail base, wherebysaid jaws m be" tightened on sa d rail base. p

- '3. E'1-in anti-creeper for railscomprising a plate having an intermediate flared gut bearmg P01171011 for engaging'fthe bottom of the rail base, 'anda; pairof terminal jaws dis-' posed so as to rigidly engage top of the;

momma rail base when said body is moved transversely of said rail base, whereby the intermediate flared-out bearing portion is distorted within its elastic limit thereby retaining said anti-creeper in position on the Ptaii base.

4. An anti-creeper for rails comprising a vplate having a pair of terminal Jaws distion upon the bottom of the rail base when said anti-creeper is in position 1E 5. 2m anti-creeper for rails comprising a plate having a pair of terminal jaws with extended curved bearing faces, dlsposed so as to rigidly engage the top of the rail base when said, body. is moved transversely of said rail base, and a flared-out portion for exerting a gripping spring action upon the bottom of the rail'base when said anticreeper is in position.

- In testimony whereof, I, the said Lnwrs O. HENGGI, have hereunto set my hand in the presence of two attesting witnesses.
