  • Publication number: 20100044451
    Abstract: The invention relates to a rail clamp for fastening rail equipment, said rail clamp being integrally composed of a polymeric composition produced by pultrusion or molding, vacuum molding or compression molding. It has high mechanical strength. It is anticorrosive and insulating and is preferably composed of a resin and reinforcing fibers and/or a thermoplastic. It is advantageously formed as a one piece structure. The rail clamp is especially used to fasten rails to base slabs and has economic advantages compared to the rail clamps known in the art, which are made of steel coated with rubber.

  • Patent number: 4155507
    Abstract: A tie plate for mounting railroad track rails on track ties in which the tie plate is formed from a corrosion resistant resilient polymer of dry self-lubricating characteristics, in which the tie plate has its upper side shaped to define along either side of the plate bearing surface to be engaged by the rail base a pair of flexible ridges each defining a flexible lip, with such lips opposing each other and terminating in a marginal edge projecting over the tie plate bearing surface. The tie plate ridges each define under their respective lips an upstanding side wall, which side walls oppose each other and are spaced apart and of a height to closely receive the rail base side edges therebetween when the rail is applied to the tie plate.

  • Patent number: 4061270
    Abstract: A unitized insulating element for use with a steel cross tie is provided. The insulating element is operative to electrically insulate the rail from the steel tie, from retaining elements associated with the tie which prevent lateral movement of the rail relative to the tie and from rail anchors which prevent longitudinal movement of the rail relative to the tie. The insulating element permits use of the rail as an on-line signal control conveying device when steel ties are used and is configured as a tie plate substitute from providing an inwardly-directed cant for the rail to be retained thereon.
