  • 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: 7874527
    Abstract: A rail fastening apparatus fastens an inner stock rail in a railway slide chair assembly. The apparatus includes a base plate. The base plate has on one face a rail seat region on which the inner stock rail sits when the slide chair assembly is in use. A resilient rail fastening clip restrains the inner stock rail. A locating means locates the rail fastening clip in a first position. A loading means vertically deflects the clip so as to produce a load in a toe portion of the clip.

  • Patent number: 7080791
    Abstract: An assembly for supporting a railroad rail on a tie includes an abrasion plate arranged to be positioned on a tie, and a pad disposed on the abrasion plate and adapted to receive the rail. The pad and plate have mating depressions and buttons arranged in complementary patterns that provides means of interlocking the two components to resist migration in both longitudinal and lateral directions. Preferably the depressions are larger than the buttons to allow some play. The two elements may be attached to each other prior to transportation by a combination of a projection on one and a capturing hole in the other. The projection may be a stake having an enlarged head. The plate may be secured to the tie by an epoxy and may have irregularities on the bottom to be gripped by the epoxy. A seal may also be provided around the supports for the rail clips to keep sand and other extraneous matter from the interface between the plate and the tie. The seal may be provided on the plate or the pad.

  • Patent number: 6342287
    Abstract: An elastic under-rail pad, made of an elastic plastic or rubber, has two opposite sides. At least one of its opposite sides presents a surface which at least partly is defined at least approximately by a simple sinusoidal or cosinusoidal trigonometric function or by a composite sinusoidal and cosinusoidal trigonometric function, so that at least on a part of one of the two opposite sides of the elastic pad there are formed protrusions (3) and cavities (4) arranged alternately and changing softly into one another. The elastic pad is used mainly in permanent ways of rail transport as an element attenuating vibrations and absorbing dynamic loads transmitted by railway vehicles to underlying rails.
