  • Patent number: 7766283
    Abstract: The invention relates to a device (1) which is used to lift and displace the tongue blade (2) of a rail (6), comprising at least two rollers (12, 14) whereby the axes thereof are arranged in an essentially parallel manner in relation to a running rail (4), in order to displace the tongue blade (2) in a transversal manner in relation to the running rail (4), at least two support carrier pins (22, 24) which respectively support a roller (12, 14), and a base body (8) which supports the carrier pins (22, 24). The rollers (12, 14) have a projection which projects in at least one first direction in relation to the base body (8). The inventive device is characterised in that a covering (10) is arranged between at least two adjacent rollers and is oriented towards the first direction and at least partially covers a passage between the at least two adjacent rollers (12, 14).

  • Publication number: 20020079634
    Abstract: A device for lifting a tongue blade (2) of points made of stock rail profiles, with a rolling device (5) includes a plurality of rollers (44, 45, 46, 47), sliding knobs, balls or the like which are orientated essentially parallel to a running rail (1), which transport said tongue blade (2) in a direction transversely to the running rail (1), and a base plate (3) which serves as rail support for said running rail (1) and which is mountable on a concrete or lumber tie, wherein said rolling device (5) can be arranged beside a longitudinal side wall of said lumber or concrete tie and is displaced downwardly such that the base of said running rail (1) and the base of said tongue blade (2) lie essentially at the same horizontal level.
