Adjustable Joint Clamps Patents (Class 238/263)
  • Patent number: 5791559
    Abstract: The temporary rail bridge (20) of the illustrated embodiment includes a bridge number (20) that is coupled to a track rail (16) by screw clamps (24). Each of the screw clamps (24) includes an internal tensioning component such as a spring (58) that allows for fast installation of the rail bridge (20) and maintains continuous pressure engagement in operation. The rail bridge (20) reduces track closure time due to rail damage and associated costs and inconvenience.

  • Patent number: 4378909
    Abstract: A fish-plate comprises two sections which can be fitted, by way of a toothed surface, against corresponding toothed surfaces of two adjacent electrically conductive rails of a railway using bolts to tighten the sections towards each other. The teeth extend longitudinally, and the sections are vertically adjustable relatively to the rails to allow the fish-plate to be clamped to the rails at various heights.
