RAIL-ANCHOR.

Specification of Letters Patent.

Patented magi, rail "r.

Application filed June 3, 1915. Serial No. 31,876.

To all whom it may concern:

Be it known that I, HORATIO G. GILLMOR, a citizen of the United States, residing at Washington, in the District of Columbia, have invented a new and useful Tm rovement in Rail-Anchors, of which the ollowing is a specification, accompanied by draw- 1112's. j p t This invention relates to devices known as rail anchors,rail stays or antlcreepers and one of the objects is to provide a simple device which will prevent the longitudinal movement of "the rails of railways.

Other objects are to provide for the automatic tightening of the device when slight movements of the rail in relation to the device occur; to prevent the loosening of the device by any accidental cause; to provlde a rail anchor which may be readily removed if desired; and to provide a rail anchor which operates with the greatest efficiency under all conditions.

The invention is illustrated in one an bodiment in the accompanying drawings, in which Figures 1, 2 and 3 are, respectively, a bottom view, a section at the plane indicated by X X in Fig. 1 and a side elevation, showing the device in operative position on the rail. Fig. 4 shows the method of applying the cross bar and Fig. 5 is a sectional view at the plane indicated by X X in Fig. 1 showing a position of the parts when bemg applied to the rail. Fig. 6 is a vlew of the cross bar and Fig. 7 a view of the tie engaging shoe.

Similar letters refer to similar throughout the several views.

In the embodiment of the invention illus trated in the drawings, A is the rail, B a cross tie, C a rail base engaging cross bar and D a tie engaging shoe. The cross bar C has at one end a aw E formed by overturning a portion F of the end of the bar. The other end of the cross bar C is formed with the arm G formed with surfaces H and I on the inside of G. The shoe D is provided with a surface K engaging the edge of the rail base when the device is in operative position and surfaces L and M to engage the surfaces H and I of the arm G of the cross bar C. The surfaces N and O of the shoe D, between which the surface K lies, are at an angle to the surface K. The shoe D is constructed with a stop P and shoulders Q and Q, the sides R and R of which parts next the arm G of the cross bar are beveled. The shoe D is base edge will just enter body ofvthe cross bar C. is then driven or between E and the The cross bar C- otherwise forced transversely on the rail to the position shown in Figs. 2 and 5 and in so doing the arm F yields somewhat and the edge of the rail base flange is firmly gripped in the jaw E of the cross bar C. With the cross bar C in this position the shoe D may be placed in the position shown in Fig. 5 with the surface L of the shoe D just beginnin to en gage with the surface H of the arm a of the cross bar and when in this position the shoe engages the rail base flange and fulcrums thereon at V. The shoulders Q and Q with their beveled surfaces R and It guide the shoe D on the arm G of the cross bar 0. The shoe Dmay now be forced to move angularly about the rail base, with which it engages at V, and the surfaces L and M of the shoe D are so formed and so placed in relation to the surface K and the fulcrum V that the forced angular movement of the shoe D will bring the surfaces L and M of the shoe D into full engagement with the surfaces H and T of the arm G of the crossbar G and will exert upon the cross bar a trans verse pull and at the same time draw the end G of the cross bar C upward and cause the cross bar C to press upward upon the rail base while pressing the surface K of the shoe D against the edge of the rail base when the operative position of the parts as shown in Fig. 2 is reached. The stop P on the shoe D coming into contact with the end of the arm G of the cross bar will prevent this forced angular movement from being carried too far. The forcing of the shoe D into position may be accomplished in several ways but it will to do this by tapping the upper end above the stop P with a hammer.

The direction in which the rail tends normally to move is indicated by the arrow in be found preferable the cross bar in the position shown the rail "carried forward with the rail in any further movement' of the rail and the cross bar C will generally provide sufficient frictional resistanceto hold the rail against forward is made to assume a position at an angle to the length of'the rail as indicated by the dotted lines in Fig. 1. The transverse and verticalpressure set-up as the shoe D is a forced into position, causing the surface K "of the shoe to be pressed strongly agalnst ,ithe' rail base edge and the cross bar to be pressed upwardly against the rail bottom movement once the portion T of the shoe is we'll in contact with the tie D. If, however, the resistance is not sufficient,'the slight angularmovement or skewing of the cross bar will greatly increase the pressure of the surface K of the shoe against the rail edge and so automatically increase the grip of the device upon the rail, and a very small movement of the rail in relation to the shoe D will be sufficient toso increase the grip upon the rail as to effectually withstand the forces tending to produce further movement. 7

It will readily be understood that if the rail, from any cause, moves backward it will carry with it the whole device and the portion T of the shoe D will leave contact with the tie. This will however not loosen ,the grip of the device upon the rail and even though the shoe be held in the ballast and prevented from backward movement with the rail the reverse movement of the rail will do no more than to tighten the device on the-rail in a ,manner to prevent further reverse movement. Moreover, the engagemen't of the shoe D with the rail and cross bar C 'isfsuch that vibration of the track and other causes cannot aifect the tightness of the parts or operate to detach the device from the rail.

It is obvious that various changes may be made in the structure described, without departing from the spirit of the invention.
