Application filed April 2, 1915. Serial No. 18,725.

To all whom it may concern Be it known that I, Hona'rro Gr. GILLMoR, a citizen of the United States. and resident of Washington, in the District of Columbia, have invented a new. and useful Improvement in Rail-Anchors, of which the following is a specification, accompanied by drawings.

This invention relates to devices known as rail anchors, rail stays or anticreepers and one of its objects is to form a simple device which will prevent longitudinal movement of the rails of railways.

Another object of the invention is-to provide means for securing the device upon the rail in such manner he lost by a reverse movement of the rail or by the vibrations to which the rail is subject.

0 the accomplishment of these objects and such others as may hereinafter appear, as will be readily understood by those the invention comprises a rail anchor, embodying features of construction, the combination of elements and arrangement of parts having the general mode of operation as hereinafter described and claimed.

The preferred embodiment of the invention is shown in the accompanying drawings, in which Figures 1, 2 and 3 are, respectively, a plan view, a side elevation and a transverse elevation showing the device in operative position on the rail. Figs. l and 5 are, respectively, a plan viewand a transverse elevation showing two positions of the device while being placed upon the rail. Fig. 6 is a section through the rail and the device at the plane indicated by the line X X in Fig. 1.-

Similar letters apply to similar parts throughout the several views.

In the embodiment of the invention illustrated in the drawings A is the rail and B the rail anchor, constructed with a tie abutting portion 0 which engages with a face of the tie D. The anchor B is constructed with shoulders E and F arranged to engage the edges of the rail base flange and a jaw G formed by the projecting rib H. For additional strength to the shoulder F and the jaw G the web I is provided. The opposite end of the anchor B is formed with an arm K arranged to engage the upper Specification of Letters Patent.

surface of the rail base flange above the tie when the tie abutting portion of the anchor C is engaging the vertical face of the tie as shown in the Figs. 1, 2 and 3. To give stiffness to this arm K the ribs or flanges L and M are provided. The tie abutting portion C is provided with a stiffening web N and the shoulder E is strengthened bv the web or flange O. U

To place the device in position on the rail it is brought below the rail with the arm K just engaging the top of the rail base flange and moved to such an angle that the end of the rib H, forming the jaw G, can

be raised by the edge of the rail base flange that its hold shall not at the side of the rail opposite to the arm K. This position is illustrated in Fig. i. In this position the shoulder E is below the rail base flange as shown. The device is now moved transverse to the rail and at the same time moved angularly in relation to the rail-until the jaw G has the edge of the rail base flange entered as shown in Fig. 5. In this position the shoulder E is still below the rail bottom and the body of the device B is subject to some torsion. If the device he now.forced to position by further rota tion of B in relation to forcing the rail edge into the jaw G, which necessary movements may be produced by tapping I transversely in refation to the rail and O longitudinally of the rail the position shown in Fig. 1 will be reached and in this position the face of the shoulder E will clear the edge of the rail base flange and the torsion of the body of B will cause this shoul der to engage the face of the shoulder E with the edge of the rail base flange. When the device B is in this position the opposite edges of the rail base flange are engaged by the-shoulders E and F as shown in the section Fig. 6.

The direction in which the rail tends to move is indicated by the arrow in Fig. 1. This movement will be referred to as the forward movement of the rail. 'As the rail moves forward it carries with it the device B until the tie abutting portion 0 comes into contact with the tie D. Thefirst effect ofany further tendency of the rail to move forward is to impart a torsional movement to B the arm K of which is engaging the upper surface of the rail base flange forwardof the tie abutting portion C, so that if the shoulder E is not already in full en- 'the rail and by' tion may be embodied having integral rail gagement with the edge of the rail base flange the torsional movement of B produced by this forward movement of the rail with C in contact with the tie D will complete the engagement of the shoulder E with the edge of the rail base flange.

The rail base flange at the side opposite to C and K is gripped in the jaw G and any further tendency to forward movement of the rail will carry forward, with the rail A, the jaw G altering slightly the angle of B to the rail A. This angular movement of B in relation to A will cause the rail edges to be more firmly gripped between the shoulders E and F and thus automatically increase the resistance which the device opposes to further movement of the rail.

Should the rail, through change in temperature'. or other cause, move in the backward or reverse direction the device B will be carried with the rail in this reverse direction and thestress on the forward face of C would be released. It will .be readily understood that even when this is the case, the engagement of the shoulders E and F with the base flange edges will prevent the vibration of the rail from loosening or disengaging the device upon the rail. Moreover, should C be held against this backward or reverse movement the jaw G would be carried backward by the rail and B moved angularly upon the rail. The effect of this angular movement would be to tighten the device and further prevent its being detached from the rail.

Obviously some features of the invention may be used without others and the invenin widely Varying forms within the scopeof the artisan.

Therefore without limiting the invention to the construction shown and described or enumerating equivalents, I claim and desire to secure by Letters Patent 1. A device for preventing the creeping of rails comprising a cross bar extending transversely under the rail and having integral shoulders thereon adapted to bear against and grip opposite edges of the rail base flange and provided at one end with an integral jaw adapted to engage the rail base flange and at the other end with an integral tie-engaging portion.

2.
