Note(s)

In this class, the following expression is used with the meaning indicated:

  • "railway systems" covers:
    1. systems in which trains or individual passenger vehicles or load carriers run on, or are guided by, ground or elevated tracks defined by rails, ropes, cables, or other guiding elements for wheels, rollers, or sliding anti-friction devices (permanently attached to a continuous traction element B65G 17/00);
    2. systems in which carriers or impellers for persons or loads are attached to, e.g. suspended from, a guided traction rope or cable which determines their path of movement (chain conveyers, scraper conveyers B65G 17/00, B65G 19/00);
    3. power and free systems of either of the above types in which vehicles, load-carriers, or loads may be selectively coupled to, or uncoupled from, continuous traction members, e.g. cables, chains.

Note(s)

In this subclass, the following terms are used with the meanings indicated:

  • "rope railways" covers railways using cables or chains as traction or suspension means;
  • "ropes", "cables", or "chains" are equivalent unless specifically mentioned.  [2]
