Abstract: A carrier for one or several electrically conductive tracks of a ground electric feeding system for a motor vehicle in the form of a strip of electrically insulating elastomeric material, comprising a substantially planar electric feeding surface of the land vehicle, provided with one or several longitudinal grooves, each groove being intended to receive a conductive track, and a surface for securing to a roadway, opposite the electric feeding surface. The carrier has a rectangular cross-section and the electric feeding surface and the securing surface form the long sides of said rectangle.

Abstract: A track for a suspended combined electric current collection and traction system including a base (22) and a resilient shield (26, 28) together defining an elongate space divided into two halves by a resilient beam (32), each of which contains a conductor (33). Spaced contact members in the form of bars (34) forming a rack on each side of the track or two rows of Z shaped contacts (82) extend through the shield and are normally spaced from the conductors. Embedded in the base are two parallel flexible metallic cables (40; 70) connected together by connectors (42; 74) by which the track may be suspended. In use, the reaction wheels (60) of a locomotive engage the tops of the cables (40; 70) thus drawing a current pick-up member (52; 86) into contact with the contact segments pressing them against the conductors (33) to pass electric current to an electric motor.

Abstract: An electric current collection system comprises a continuously live conductor, a shield enclosing the continuously live conductor, and contact segments extending through the shield in a row extending along the length of the continuously live conductor and resiliently mounted so as normally to be electrically isolated from the continuously live conductor and from each other but adapted to co-operate with a current collecting device running along the row to make electrical contact with an external contact surface of each segment in succession and displace the segment to bring an internal contact surface afforded by it into electrical connection with an internal contact surface afforded by the continuous live conductor. Each segment includes a bar portion affording an internal contact surface and extending through the shield in a direction substantially perpendicular to the length of the live conductor and to the direction of displacement of the segment.

Abstract: A roadway having a smooth road surface for automotive vehicles includes means for transmitting electric current through the road surface to electrically-operated vehicles travelling thereon. Each electrified traffic lane is provided with at least two spaced parallel electrical contact assemblies mounted with their top surfaces flush with the road surface and in position to be contacted one with a wheel on each side of the vehicle, with the contact assemblies each requiring a predetermined weight thereon to maintain electrical contact with the vehicle wheels. The vehicle employs electrically-conductive tires which roll on the electrically-conductive surface of the contact assemblies, and the current thus picked up is transmitted, through rolling-sliding contacts, conductors, etc. to controls for controlling the operation of the vehicle through individual wheel motors.
