  • Patent number: 6257495
    Abstract: A device for securing railway rails (12) on a solid track includes a standard concrete sleeper (16) used for the ballast track. Each of the rails (12) is guided between two angle guide plates (30) and urged by a tensible clamp (34) against the concrete sleeper (16). A resilient intermediate plate (52) is disposed between the rail flange (14) and the standard concrete sleeper (16) and, at their ends remote from the rail (12), the angle guide plates (30) include a first (24) and a second surface (28), the first surface (24) being inclined obliquely to the vertical in the mounted position and abutting a correspondingly shaped sloping surface (44) of the standard concrete sleeper (16). The second surface (28) is aligned substantially vertically and rises over the top of the standard concrete sleeper (16).

  • Patent number: 5096119
    Abstract: The invention concerns a rail fastener on concrete ties (4) or the like including resilient tension clamps (6) of steel rods in the form of a W and angled guide plates (3) for the rail base (1a). This so-called HM rail fastener is inventively improved by a special shaping of the tension clamp and angled guide plate, to simplify the securing of the rail on the concrete ties, in that the rotation of the elastic strainers which was previously necessary in HM construction when passing from the preassembly to the assembly position is omitted. This is achieved in that the angled guide plate (3), which is provided with a rib (3a) extending longitudinally to the rail foot for abutment on the rail foot (1a), contains in this rib special recesses (3b) for the reception and retention of the free ends of the tension clamp in the preassembly position.

  • Patent number: 4718603
    Abstract: Anchor for a railway tie embedded in ballast. In order to further simplify the installation of such an anchor, the clamp is constructed in two or more parts. With an anchor construction having a clamp gripping the tie on both sides, the clamp parts are constructed of approximately the same size in order to form clamp halves, the connection is formed as a pivot arrangement and in the region of the connection position a tightening means is provided for producing a tightening force clamping the clamp halves on the tie.

  • Patent number: 4718604
    Abstract: The invention describes a clamp for rails that is produced from resilient steel bar with multiple bends. The first section (11) of the rail clamp (9, 10) is essentially horizontally arranged, while the last section (14) rests on the rail flange (5). The second section (12) curves upwards in the vertical plane that passes through the first section (11). The remaining sections of the clamp lie all on the side of the first section that faces the rail. The fastening arrangement comprises an anchoring part (20) where the supporting surface (23) for a supporting section of the clamp (9, 10) is located essentially vertically above the locating hole (24) of the clamp (9, 10). That produces a relatively short clamp requiring a minimum of material.

  • Patent number: 4705215
    Abstract: The invention relates to a rail securing arrangement, which has the following features. It comprises metal plates, each of which lies with its flat lower surface on the sleeper, and on whose upper surface two ribs are formed which extend in the longitudinal direction of the rail, and between which the foot of the sleeper lies on a bearing surface. On both sides of the rail in the region of the respective ribs, each plate has moreover at least one through-hole, with which a respective through-hole in the sleeper is aligned. Corresponding screws are each introduced with their lower ends into the respective through-holes of the plate and engage with a hook-like bend beneath the lower surface of the plate. Each screw is provided at its upper end with a thread onto which a respective nut is screwed. Furthermore, the securing arrangement comprises plate-like securing elements which are each bent to form a double-armed angle member.
