  • Patent number: 6651897
    Abstract: A railway rail fastening assembly, for suspending a railway rail (100) at discrete locations along its length above a rail foundation, comprises a pair of elastic members (5) for support the head of the rail (100), a pair of brackets (6) for applying a lateral clamping force to respective ones of the elastic members (5), a baseplate (1) having first and second shoulders (3,4), and a pair of wedge members (7), each wedge member (7) being inserted between an associated one of the shoulders (3,4) and an adjacent bracket (6) thereby to maintain the said lateral clamping force, wherein at least one (4) of the said first and second shoulders (3,4) is removable from the said baseplate (1) and is held in position on the baseplate (1) by the said lateral clamping force.

  • Patent number: 6079631
    Abstract: A railway rail support assembly (3), for resiliently suspending a railway rail (1) above a track foundation (2) at discrete locations along the rail (1), has rail supporting means through which a predetermined clamping load is exerted on the said rail (1) such that the assembly (3) has a desired resistance to longitudinal creep therethrough of the rail (1). The rail supporting means are preferably attached, when the assembly (3) is in use, to an approximately horizontal upper surface of the said track foundation (2). Such an assembly (3) may be provided by first and second brackets (31, 32) and first and second elastic members (33, 34). Each of the said first and second brackets (31, 32) has a bearing part (312, 322) and a base part (311, 321) (311, 321), the bearing part (312, 322) being located adjacent to either sides of the rail (1) when the assembly (3) is in use and the base part (311, 321) being located on an upper surface of the said track foundation (2).

  • Patent number: 5718376
    Abstract: A resilient rail-fastening clip has a first straight portion (11) for locating the clip in a clip anchoring device (2) when the clip is in use, a second bent portion (12), a third heel portion (13), a fourth bend portion (14) and a fifth toe portion (15). When viewed such that lower most points of the first and fifth portions (11 and 15) of the clip lie in a horizontal plane, proceeding from the first portion (11), the second portion (12) appears to bend up out of that plane towards and then away from a vertical plane passing through the fifth portion (15). The clip (1) is used in an assembly including a baseplate (2) having a non-vertical stop (21d) on its shoulder (21) up which the clip (1) slides during installation until brought to rest through friction at a desired height above the rail (3).

  • Patent number: 5678762
    Abstract: In an assembly for use in fastening a railway rail to an underlying rail foundation, a resilient railway rail fastening clip (1, 2,3) has at least one portion (1a) which when in use bears on, and extends substantially parallel to, a flange (301) of an adjacent railway rail (300), and retains an insulator (13, 13') for electrically insulating the clip (1, 2, 3) from the rail (300) when in use. The insulator (13) is held in engagement with the clip (1, 2, 3), which has a rail bearing portion of substantially circular cross-section, such that it can rotate about the longitudinal axis of the said rail bearing portion (1a). Unlike the prior art the insulator is self-aligning on the rail flange (301) when the rail (300) moves. One insulator (13, 13') disclosed has at least two load bearing surfaces (13a), such that it may be rotated so as to present an unworn load bearing surface (13a) to the rail flange (301).
