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.
