  • Patent number: 10132044
    Abstract: Rail clip assembly (1), comprising superposable first (10) and second bodies (11) arranged for being removably fastened to a rail support by a connector (9). The first body (10) comprises an abutment surface (121) adapted for abutment with a lateral face of a foot of a rail. The first and second bodies comprise corresponding apertures (122, 112) for receiving the connector (9), one (122) of the apertures being oblong with a longer axis (150) extending in a direction oblique to the abutment surface, to enable the first body to assume different positions relative to the second body. The first and second bodies comprise first corresponding surfaces (123, 111) configured for providing force transmitting contact between the first and second bodies when assembled.

  • Patent number: 7954727
    Abstract: A shoulder for use in retaining a railway rail fastening clip, comprising two interconnected spaced-apart walls, between which a portion of the clip to be retained is held when the shoulder is in use, and clip-engaging means, supported by the walls, for engaging a portion of the clip to be retained, does not have any feature or surface which engages the surface of that clip portion which faces downwardly when the clip is in use. Alternatively, or in addition, none of the contact regions, at which the device engages the rail clip, can be seen when the anchoring device is viewed from above when in its operative orientation and all of the contact regions can be seen when the anchoring device is viewed from below when in the operative orientation. Alternatively, or in addition, all the contact regions lie substantially at the same horizontal distance from the edge of the rail foot when measured perpendicularly to the axis of the rail and in the plane of the rail foot.

  • Patent number: 7793857
    Abstract: The invention relates to fixing means for fixing railway lines to sleepers or stretches of track, comprising an elastic rail clip (51) and a clip anchor element (31). According to the invention, the elastic rail clip (51) has retaining elements that can be inserted into the clip anchor element (31) and guided into the latter by being rotated about a rotational axis (D) and at least one pressure bow (52), which can be brought into pre-tensioned contact with the foot (24) of a railway line (21), when the elastic rail clip is rotated (51) about the rotational axis (D) in relation to the clip anchor element (31). The elastic rail clip (51) has essentially annular clip bows (55, 56) that act as the retaining elements and the clip anchor element (31) has guide elements (34) that are concentric with the rotational axis (D).

  • Patent number: 5566882
    Abstract: A railway rail fastening clip (1) suitable for holding down a railway rail (2) is formed from a rod of resilient material bent so as to be approximately M-shaped in plan, the clip (1) being such that, when it is bearing on the flange of a rail (2), the longitudinal axis of a part (14) thereof, which interconnects inner legs (13, 15) of the M, lies in a reference plane which is substantially parallel, but not identical, to a plane containing the longitudinal axes of outer legs (11, 17) of the M. Such clips (1) are used with an anchoring device (5), which, as the clip (1) is installed therein, deflects the outer legs (11, 17) downwardly with respect to the inner legs (13, 15), so as to place the clip under stress.
