摘要： A resilient mounting for a rail on a concrete sleeper which has a flexible liner between the ground or base flange of the rail and the sleeper and a mounting clamp on opposite sides of the base flange forming a flexible nylon or polyacetal resin rail restrainer which overlies and engages the base flange and the sleeper. A bowed spring plate overlies the rail restrainer and overhangs beyond the edge of the restrainer above the base flange of the rail, with a clamping bolt extending through the bowed spring plate and rail restrainer. The spring plate is bowed into an arcuate configuration in a plane parallel to the longitudinal axis of the rail, at least at the edge adjacent the rail, and become flattened during tightening of the clamping bolt drawing the spring plate into compressing engagement with the rail restrainer.

摘要： A resilient fastener for fastening a rail on its support, comprising a flexible blade of constant thickness having a longitudinal edge to be disposed parallel to the axis of the rail and applied against the rail flange. The blade has two orifices spaced from the longitudinal edge and arranged so that they are situated above the rail support and close to the edge of the rail when in fastening position. The longitudinal edge is curved to a convex shape presenting a substantially cylindrical surface of which the directrix is a curve inscribed between the warped shape assumed by the blade when loaded in its center and the arc of a circle passing through the blade center and the centers of the orifices.

摘要： This system for fastening a rail comprises an elastically yieldable fastener and a clamping device which extends through the fastener, an elastically yieldable block provided with a central aperture for the passage of the clamping device and a cap. The cap is in the form of a cup which is provided with a central aperture and is extended around the cup aperture by a tubular sleeve. The block is placed in the cap. The internal volume of the cap is less than the volume occupied by the block when it is compressed, whereby, in the course of the clamping of the clamping device, the lateral expansion of the block is limited by the cap and its axial elasticity is maintained.

摘要： The fastener structure comprises at least one main bending strip which defines an aperture for the passage of a clamping bolt for the fastener structure. An elastically yieldable second strip extends transversely of the general direction of the fastener structure and is curved in the direction of the length of the second strip and has its concavity facing the main strip. The two ends of the second bear against the edges of the main strip.

摘要： The elastically yieldable fastener comprises an elastically yieldable strip bent onto itself and forming two superimposed branches. A clamping device extends through apertures in the two branches for clamping the strip to the support of the rail. The upper branch has a boss disposed between the aperture of the upper branch and the free end of the latter and between lateral portions of the upper branch which are adapted to bear against the lower branch when the strip is clamped by the clamping device. The clamping device defines a lower surface for contacting the upper surface of the boss and the two surfaces have the same shape so that, in the normally clamped position of the strip, the portion of the branch carrying the surface contacting the clamping device is raised with respect to the lateral portions.
