<p>. ELASTICALLY YIELDABLE DEVICE FOR FIXING A RAIL ON A SUPPORT The device comprises a spring (8) fixed to a support at a point remote from the rail (1) and curved in the direction of the rail, and a swing block (16) interposed between the spring and the flange of the rail. The swing block bears against the flange (11) of the rail at one end (17) and against the support at its opposite end (18). The swing block is clamped by the end (15) of, the spring which applies a clamping force at point located at a distance from the flange of the rail but in the vicinity of the flange so that the two lever arms of the swing block have very different lengths. Further, the spring has a thickness which decreases in the direction of the rail and bears against the swing block by its end (14) which is curved, the swing block having a corresponding shape under said end.</p> |
