Rail Sleeve Patents (Class 238/248)
  • Patent number: 7735745
    Abstract: The present invention is directed at an improved device for joining together abutting railway rails between two railway ties. The rails to be joined together have a head portion, a web portion and a toe portion. The joining device includes first and second elongated metal joint bars for holding the abutting ends of the rails together. The joint bars span the ends of the rails and hold the rails together by mounting to the rails. The joint bars are mounted to each rail on opposite sides of the web portions of each rail. The joint bars are configured to mount to the web portions of the rail between the head and toe portion of each rail.

  • Patent number: 7735746
    Abstract: The present invention is directed at an improved device for joining together abutting railway rails between two railway ties. The rails to be joined together have a head portion, a web portion and a toe portion. The saddle is split at the bottom and joined with the two bottom (lower) bolts. The saddle hugs the base of the rail at the joint preventing differential vertical (shearing) displacement of the two rail ends. This can be used in insulated and non-insulated joints. The bolts are isolated from the bars and saddle and directly contact the rail.

  • Patent number: 5533670
    Abstract: A rail joint for interconnecting two successive rail bars of a railroad track includes longitudinally aligned first and second guide rails. Each of the guide rails has a mounting end adapted to be secured to a respective one of adjacent end portions of the rail bars, a distal end opposite to the mounting end and spaced from the distal end of the other one of the guide rails at an expansible space, and a downwardly and longitudinally extending dovetail projection. A connector is adapted to be fixed on the railroad track and is formed with an upwardly opening and longitudinally extending dovetail groove for receiving fittingly the dovetail projections of the guide rails therein so as to maintain alignment of the guide rails.
