  • Patent number: 4634049
    Abstract: A concrete crosstie has a recess for holding a rail securing member engaging beneath a nose in the recess. Upper ends holding the rail down resiliently are loop-shaped, to obtain a low surface pressure at two spaced areas and exact positioning of the rail securing member in the recess. The greatest possible crosstie cross-section is retained in that the recess only partially penetrates the concrete crosstie. The nose lower and side faces and the rail foot support surface are formed by steel reinforcements connected to the concrete.

  • Patent number: 4339077
    Abstract: A rail mounting system for mounting ties on concrete rails includes one or more concrete rails each having an upper surface from which a passage extends inwardly and downwardly and diverges in downward direction. For each passage there is provided a rail mounting member having a shaft provided at its upper end with a springy portion and at its lower end with a claw which extends laterally of and is inclined to the shaft. The upper open end of the passage has an outline corresponding to a vertical projection of the claw onto the surface of the tie.

  • Patent number: 4113178
    Abstract: A resilient rail connection on railway ties or the like with guiding plates located laterally of and adjacent to the rail. Each of the guiding plates along a section perpendicular to the longitudinal extension of the rail has a first end portion of an upwardly opening angular shape and an oppositely located second end portion for cooperation with a spring element. In fully assembled condition of the rail connection, the angular first end portion of each guiding plate rests in a correspondingly shaped recess arranged in the rail supporting under-structure such as a railway tie while being located remote from the rail, whereas the second end portion of each guiding plate is adjacent the foot portion of the rail and is under preload engaged by the spring element which resiliently rests on the same under-structure as the first end portion and urges the second end portion of the guiding plate upwardly.
