Abstract: 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.
Abstract: The present invention relates to a new device for elastically fastening a railway rail by locking on a tie-plate, which device comprises two parts, a relatively flexible part placed above the rail flange, and a relatively rigid part situated where the device is wedged in on the tie-plate.
Abstract: 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.
