  • Publication number: 20120181344
    Abstract: An electrical insulator for use with a rail fastening clip comprises a contact member providing on one side a substantially flat rail contact surface for contacting a foot of a rail and on the opposing side a clip contact surface for contacting a rail bearing surface of a bearing portion of the clip, the insulator also having retaining means for retaining the insulator on the clip in such a way as to allow rotation of the insulator about a longitudinal axis of the bearing portion of the clip. The insulator has stop portions for limiting such rotation about the longitudinal axis of the bearing portion of the clip to a desired extent. The clip contact surface of the insulator is convex, in a vertical plane which is perpendicular to the longitudinal axis of the bearing portion of the clip, such that, when the insulator is attached to a clip having a flat rail bearing surface, a contact region between the flat rail bearing surface of the clip and the clip contact surface of the insulator is linear.

  • Patent number: 8201751
    Abstract: In a railway rail pad having a rail seat portion for receiving a foot of a railway rail, the rail seat portion is provided on at least one major face thereof with a plurality of protrusions which are unevenly distributed across the face of the rail seat portion such that the ratio of the area of the face occupied by the protrusions to the area of the face free of protrusions is greater in an edge region of the rail seat portion than in a central region of the rail seat portion, the edge region being adjacent to one edge of the pad and the central region being adjacent to the edge region. The studs are arranged in columns, each stud being of substantially the same size, and the number of studs in a column in the central region which is closest to said edge region being greater than in a column closer to the center of the rail seat portion.

  • 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.
