Abstract
A self-propelled member or carriage runs along a stationary surface-conducting cable formed of alternately disposed conducting and insulating turns. The carriage is provided with a rotor extending around the cable and having contacts in a conductive relation with the conducting turns of the cable. At least two pulleys are rotatably mounted to the carriage with the cable interposed between the pulleys. An electric motor is operatively electrically connected to the contacts of the rotors and is drivingly connected to the pulleys. Electric power is transmitted from the cable by the rotor to the motor whereupon the motor drives the pulleys to propel the carriage along the cable.
Claims14
A cable-way system comprising:
- an electrically conducting cable having alternately disposed electrically conductive and non-conductive turns at the outer surface thereof;
- and a self-propelled member moveable along said cable, said self-propelled member including a rotor extending around said cable and rotatably slidable over the same, the rotor having contacts in an electrically conductive relation with said electrically conductive turns for drawing electric power from said cable, at least two pulleys, between which said cable is disposed, rotatably supported on said self-propelled member, an electric motor operatively electrically connected to said rotor so as to receive electric power drawn by said contacts, and said motor being mechanically connected to at least one of said pulleys for rotating the same to cause said self-propelled member to move along said cable, and means for coupling auxiliary devices to the self-propelled member.
