HOBATIO G. GILLMOR, OF WASHINGTON, DISTRICT OF COLUMBIA.

RAIL-STAY.

Application flle d May 7, 1915.

To all whom it'may concern:

-Be it known that I, HORATIO G. GILLMOR, a citizen of the United States, and a resident of lVashington, in the District of Columbia, have invented a new and useful Improvement in Rail-Stays, of which the following is'a specification, accompanied by drawings.

This invention relates to devices known as rail sta s, rail anchors or anticreepers and one 0 its objects is to form a simple device which will prevent the longitudinal movement of the rails of railways.

Another object of the invention is to provide for an increase of the gripping action of the device whenever slight forward movement of the rail occurs.

A further object is to provide certain arrangements whereby the elements of the device are held in gripping engagement with the rail as against any forces, such as those" set up by changes of temperature, vibration, etc.,- tending to produce a loosening-of the device upon the mi];

The invention is illustrated in a preferred embodiment in the accompanying drawing, in which:

Figures 1, 2 and 3 ape, respectively, a bottom view, a side elevation and an end elevation. Fig. 4; is a section through the arts at the plane indicated by X X in l ig. 1, showing the relative position of the parts when the rail stay is being applied Fig. is a View of thecross bar and Fig.6 a view of the tie-engaging keV. f

imilar letters apply to similar parts throughout the 'several views.

Inthe embodiment of the invention illustrated in the drawings A is the rail, B the cross tie, C the rail .base engaging cross bar and D the tie engaging key. The cross bar has a jaw E at one end, formed by overturning a. portion F of the end of the bar aml' the end of F is rounded at G to facilitate the engagement of the jaw E with the base of the rail A. The other end of the cross bar C has an arm H the end of which is fw' ned with surfaces I to the upper surface of the rail base and a surface K to engage the rail edge. At L, the cross bar C is provided with curved surfaces arranged to engage surfaces M of the key 1). The cross bar C is preferably, though not necessarily, formed of spring steel and has, in its normal unstrained condition. the form shown in Fig. i. The key I) D.

ing the key D in engagement with the cross bar C, as illustrated in Fig. 4, and

then applying the cross bar transversely to the rail with the rounded part G of the arm just about to engage with the upper part of the rail base and engaging the opposite upper surface of the rail base. The cross bar and key are so formed as to permit them [to be placed in approximately the position illustrated in Fig. 4. without the use of much force and, in this position the cross bar will engage the bottom of the rail at T. The jaw E is so formed that when the cross bar C is in operative position the rail base will be firmly gripped by the jaw E. To get the parts into this operative position the cross bar C is driven transversely and, while so driven the cross bar C will fulcrum at T and forces will be exerted tending to pull the arm H downward. As soon as the cross bar C has reached the proper position these forces will cause the surface K of the shoulder to engage the edge of the rail base. The arm H will be lowered somewhat and the key D will take up a new position the surface M moving on the surface L of the cross bar. To complete the locking of the parts in operative position the key I) is forced to 'move angularly about the cross bar C. until the surface U is in full engagement with the rail bottom. This angular movement of the key D pulls the arm H downward, causes the surface I of the arm H to press down upon the upper surface of the rail base and the surface K of the cross bar C to press transversely against the edge of the rail base and strain the body of'the cross bar C so that the cross bar, in tending to resume the form from which it was sprung, presses the surface U of the key I) upward against the rail bottom. The key I) is rounded at V to facilitate the driving of the key into position. From the form of the key it will be seen that when the key is in its final position as shown in Fig. 3 it is locked against angular movement in the plane of the cross bar by the engagement of the surface U with the rail bottom against which it is pressed by the pressure of the cross bar C upon the key The engagement of the surface K of the cross bar C, with the vertical edge of the rail base prevents any transverse move ment of thecross bar C upon the rail base, and the parts are thus securely locked in their operative positions so that the device cannot be loosened or detached by vibration or reverse movement of the rail.

The arrow in Fig. 2 indicates the direction in which the rail tends to move and this direction will be referred to as forward and the reverse direction as backward. The grip of the jaw E upon the rail base is such that, as the rail moves forward, E is carried forward and the cross bar tends to assume the skewed position, indicated by thetlotted lines in Fig. 1, the body of the bar 0 being held against the forward movement at R by the engagement with the shoulder Q of the key D, which is held by the engagement of the face 0 with the tie. The arm H of the cross bar C'coacting with the key D grips the rail base between the surfaces 1 of arm H and U of he D and tends also to move forward with t e rail with the effect that 'the cross bar is canted from the vertical, as indicated by the dotted lines in Fig. 2. The

skewing of the cross bar (I causes the rail base to be gripped between the yaw E and the shoulder K with increasing (force; and,

at the same time, the stress in the transverse,

portion of the cross bar C tendsto press the key D upward against the rail bottom. The canting of the cross bar C from the vertical still further greatly increases the downward pressure of the surface I of the arm H and the upward pressure of the surface U of the key D upon the rail base flange. In

this way even small movements of'the rail, by the double action described, so greatly increase the grip of the device upon the rail as to eliectually hold the rail against further forward movement.

Backward movement of the rail will carry with it the entire device the face '0 of key D leaving contact with the tie li If the key D should be sufliciently held by the ballast or by contact of the tie engagin face N -with the tie adjacent to the tie B hecross bar might resume the position shown by the full lines in Figs. 1 and 2 and might even move in the backward direction out of the transverse and vertical, but the device will still be so effectually looked upon therail that no movement of this kind nor any vibration of the rail will loosen the device.

1 construct the key D with tie engaging faces N and Oso that the device may be applied to the rail with either side to the tie or engage faces of two adjacent ties. This has the advantage of simplifying the application and makes the devicev adaptable to special conditions and available for limiting creeping movement of the rail in either direction.

Obviously some features may be used without others and the inven tion may be embodied in widely varying forms, within the skill of 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:
