  • Patent number: 8033480
    Abstract: Fastening for a rail and arrangement for fastening of rails The invention relates to a fastening for a rail for securing a rail (10) whose foot is resting on a concrete sleeper (16), comprising at least one elastic clip (20) having several legs of which at least one leg extends inside a shoulder (42, 44) or channel of a holder (24) that is connected to the concrete sleeper, and at least one further leg rests on the rail foot. For securing a rail to the necessary extent with simple design means and in space-saving form, it is suggested that the holder (24, 26) is arranged detachably in the concrete sleeper (16) or in a plate element resting thereon and is connected to the concrete sleeper by a bolt element.

  • Patent number: 7874527
    Abstract: A rail fastening apparatus fastens an inner stock rail in a railway slide chair assembly. The apparatus includes a base plate. The base plate has on one face a rail seat region on which the inner stock rail sits when the slide chair assembly is in use. A resilient rail fastening clip restrains the inner stock rail. A locating means locates the rail fastening clip in a first position. A loading means vertically deflects the clip so as to produce a load in a toe portion of the clip.

  • Patent number: 7309050
    Abstract: A grooved rail core piece including a core piece intersection area formed by intersecting grooves as an overflow area. The core piece has two construction profiles with interconnected outer fishing surfaces (22,24) extending in a longitudinal direction. In order to enable the intersection area of the core piece to be renewed in a simple manner, the intersection-point area of the core piece includes an interchangeable insert (36) which is arranged in a recess in an at least positive fit, the recess being defined by the sections of the construction profiles and by the sections of the lining parts (30,32) disposed in the outer fishing surfaces (22, 24), and the insert is fixed by means of at least two wedge elements (38, 40) which can be clamped in the lining parts. The lining parts and the construction profiles are connected by means of at least one clamping element protruding there through in a non-positive fit.

  • Patent number: 7137601
    Abstract: A check rail arrangement for a switch or an intersection, the arrangement including a grooved rail (16) provided with a grooved rail head (14), a groove (18) and a lip (52), and a check rail (12) which is supported at least on the lip and is arranged by a fixing mechanism in such a way that it can be displaced in relation to the grooved rail. The aim of the invention is to be able to easily displace the check rail. To this end, a fish-plate block (40) extends from the grooved rail (16), the fish-plate block including a longitudinal groove (42) which extends perpendicularly to the longitudinal direction of the grooved rail and in which a slot pin (44) engages in an adjustable manner. The slot pin can be tightened by a screw (46) extending from the check rail (12).

  • Patent number: 6860433
    Abstract: A bearing for a section of a track includes, along the track sections, profile sections which deviate from each other, especially in the form of points. A plurality of supporting points is provided with a ribbed plate, in addition to an intermediate layer made of an elasticized material disposed between the ribbed plate and an associated railway sleeper. In order to obtain identical subsidences along the sections of track, substantially each support point has an identical maximum subsidence with respect to each excavated track section.

  • Patent number: 6543728
    Abstract: The invention relates to a cross frog (10) for points and crossings, comprising a cross frog tip (14) and wing rails (16, 18) and running rails (20, 22) situated either side of this point, each with a basic course (38) aligned with a main or secondary track (26, 28). The aim of the invention is to reduce the wear around the cross frog tip without reconstructing the cross frog tip itself or the guard rails allocated thereto or realigning them in relation to each other. To this end, at least one of the running rails deviates from its basic course in the area of the cross frog tip, in such a way that the movement of a rail vehicle running through the main or secondary track is influenced through its wheel frame or bogie axle, away from the cross frog tip.
