surfaces F and U with it and the cross bar assumes a position at an angle to its original position as indicated by the dotted l nes in Fig. 1. The drawing of the surfaces I of the portion H of the cross bar G into contact with the rail base edge by the forcing of the key D into position has caused the'rail to be gripped between the surface I of portion H and the surface V at the bottom of the jaw at the other end of the cross bar. The angular movement or skewing of the cross bar C will increase the grip of the cross bar 0 upon the rail. The resistance of the device to further creeping movement is thus increased automatically by this movement of the cross bar. The key D is held by the contact of the tie engaging portion S with the face of the cross tie and the pressure transmitted through key D sets up tending to turn or cant key D slightly on the rail. The surface M in contact with the rail is relatively short longitudinally of the rail so that the moment thus set up causes the keyD to cant slightly as indicated by the dotted lines in Fig. 3. This action increases the vertical ressure, produced by the key, of the cross ar C upwardly upon the rail bottom and therefore still further increases the resistance of the device to furthei movement of the rail in the forward direction. This actioncontinues until the resistance to forward movement is equal to the forces tending to produce forward movement and generally a very slight forwardmovement of the rail will be suflicient to make the grip of the device upon the rail sufiicient to withstand all the forces tending to move the rail forward. If the rail through temperature changes moves in the backward direction the first effect will be to carry portion S out of contact with the face of the tie. If the key should be held in the ballast there might be some angular movement of the cross bar upon the rail base but the cross bar would continue to grip the rail between surfaces F and G so that whenever movement in the forward direction again occurred the gripping action of the device would again become effective. The engagement of the key I) with the cross bar and rail will readily be seen to be such that the tightness of the key D cannot be effected by vibration or other accidental causes.
