  • Patent number: 4927102
    Abstract: In a reversing device for movable parts of a railway switch within the deflection area of a railway switch, in particular tongue rails, monorail deflection device or movable stock rails, in which device the movable rails can be caused to contact rigid switch parts, the movable rails are supported in their contacting position by supporting rods extending in the longitudinal direction of the rail the supporting rods are slideably guided on the sleepers or, respectively, base plates in the longitudinal direction of the rails. In this case, the supporting rods are designed as adjusting members for the reversing operation and comprise thrust supports cooperating with thrust supports of the movable rails for shifting the rails. At least one of the mutually cooperating surfaces of the thrust supports of rail and/or of supporting rod is formed of a wedge surface passing over into a supporting surface extending in an essentially parallel relation to the longitudinal direction of the supporting rod.

  • Patent number: 4224875
    Abstract: A static switching apparatus for a track vehicle includes a main line track and a switch track which at a switching junction both include a conventional track rail and a specially constructed rail. A switching cam including cam faces is positioned at the junction and includes straight and curved cam surfaces which are selectively engaged by cam followers supported on the vehicle to provide for steering of the vehicle. The cam followers are lowered and raised vertically by fluid extensible devices which also move them in an orbital path into cam surface engagement.
