To all whom it may concern:

'Be it known that I, HoRA'rI'o G. GILL- MGR, a citizen of the United 'States,- residing at'Washington, in the District of Columb a, have invented, a new and useful Improvement in Rail-Anchors, of which the following is a specification accompanied bydrawm s. 'lhis invention relates to devices known as rail anchors, railstays oranticreepers 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 against .renderingthe deviceinoperative by reverse movement of the rail or by the efiects of vibration.

To the accomplishment of these objects and such others'as may hereinafter'appear, as will 'be readily understood by those skilled in the art, the'invention comprises a rail anchor embodying the features of construction, the combination :of elements and arrangement of 'parts 'havingthegene'ral mode of operation as hereinafter described and claimed. p g

The preferred embodiment of the invenings, in which tion is shown in the accompanying drawview, a side elevation and a transverse elevation showingthe device in operative posi tion onjthe rail. Fig. 4 is a plan View showing the manneiqof applyingthe crossbar and Figs.f5 and 6 are,; respectively, a side elevationand an end elevation of the cross bar."

Similar letters apply to similar parts throughout the several views.

In" the embodiment'of the invent-ionillustrated in the drawings, A is the rail, .13 a cross tie,IC a tie plate andD a crossbar. The cross bar D is preferably rectangular in section and'has one end turned back at an angleto the bod of the bar as atE-to form an arm .to engage the upper surface of therailhaseifiange. This arm is turned inthe plane of theidiagonalof the cross: sec- 5 tionofthe bar as shownrin Figs. 5 and 6 and presentstwo facesFand'. G, either ofwhich may engage'the upper surface of the baseflange'of therail. The other end of the bar is turned to approximately right angles to -the fa'ceof'the body of at andtherefore has a'face'I parallelto the Fig. 4c. 7 driven or otherwise forced transverse to the face F ofthearm E. The turning *of the 'railzand the distance between -K andL is made to slightly exceed the width of the base flange of the rail The tie plate 0 is provided with a projecting portionM, upon which is formed a portion N arranged to engage the bottom andone side of H'below the rail and an upwardly turned portion 0 having a portion P arrangedto engage H above the rail base and at the side opposite to that engaged by M. The tie plate C is flanged down at'Qto form a tie abutment To apply the device the cross bar D is placed on the rail with the face'F of the arm E engaging the upper surface of the base flange at one side of the rail and the bar D transverse to the rail. In this position the arm H has its, facel, which is parallel to F, in contact with the bottom ofthe rail base. 1 The arm E is so arranged that itis necessary to stress the "arm and its connection to Figures 1,2 and 3 are, respectively, aplan the bar in order to'force D to a position in ofthe railbase. A position of the bar D shortly before this is reachedis shown in From this position the barD is engaging the vertical face of the tie, to take 7 "the thrust transmitted by the bar {D to'the tie plate when the railjmoves in the direction of'the arrow. The'tie plate is further secured-to the tie by spikes R.

frail until L reaches the rail edge. The bar v D is subject to some torsion while being so driven and as soon as H passes the edgeof the rai1 it tends to turn toward the vertical position. While 'so'turning the face F of 'the arm E leaves the-upper "surface ofthe rail and thisarm'E assumes a position in which neither the "face F nor the face G is in contact with the upper surface of the rail base. By forcibly turning Htoward the vertical .ho'wevertlie,face G'of the arm E v tact withthe edgeof the rail base and the other abutment L onfHin contact" or nearly in contact withfth'e. other edge of the rail sition with the portion-M engaging Hat the bottom and on the side'below the rail and P engaging H at the other side above the rail base. The fit of the parts is preferably so arranged that the projecting portion M of'C has to be forced into position by driving or otherwise on to the rail base so gripping the rail base between P and the body of C and at the same time forcing H to the vertical position and so setting up torsion on D and causing the base flange to be gripped at the opposite side of the rail between the arm E and the body of D.

The direction in which the rail tends normally to move is indicated by the arrow in Fig. 1 and this direction will be referred to as forward and the reverse direction as backward. It will be readily understood that if the rail tends to move forward the end carrying the arm E of the bar D will be carried forward with the rail and the other end of D will be held by the engagement of H with the portion M of the plate C. The cross bar will, therefore, move angularly or skew slightly on the rail A and this action will cause the crossbar D to grip the rail base edges between the abutments or shoulders K and L and so hold the rail against further forward movement.

The thrust of the crossbar in the forward direction is taken up by the flange Q of the plate C engaging the face of the tie as illustrated in Figs. 2 and 3.

If the rail for any reason moves in the backward direction the crossbar D will be held at one endfby the engagement of the portion P of the plate G with H while the other end of the bar D will be carried backwardly with the rail. The first effect of this movement will be to release the grip of the abutments L and K upon the iail edges; but, as'the movement of the rail backwardly continues the cross bar will be skewed or moved angularly until the base edges are again gripped by these abutments K and L and the grip of the cross bar upon the rail sufficiently increased to withstand the forces tending to produce further backward movement of the rail. The movements of the rail will in this way be limited to such small movements as are necessary to bring about the skewing of the cross bar D necessary to produce the necessary grip of K and L upon the rail edges to meet and offset the forces tending to produce the movement.

For the forward movement the resisting.

force is transmitted to the tie by the tieengaging flange Q of the plate C and forthe backward movement the resisting force is transmitted to the tie through the plate 0 and the spikes R. V

Obviously some features of the invention may be used without others and the inven- .tion may be embodied in widely varying forms within the scope of the artisan. 7 Therefore without limiting the invention to the construction shown and described or enumerating equivalents, I claim and desire to secure by Letters Patent 1.
