Abstract
A trolley rail housing provided with a plurality of parallel open-bottom slots extending lengthwise thereof has an electric conductor mounted up in each slot, with an end portion of the housing offset upwardly and connected by a downwardly inclined portion to the rest of the housing. An electrical pick-up unit adapted to be carried by a vehicle includes a plurality of collectors mounted for vertical and lateral movement, with spring means urging the collectors upwardly. This unit also includes a pair of laterally spaced guide members disposed above the collectors and movable laterally with them and adapted to engage the opposite sides of the rail housing when the pickup unit, separated from the housing, is moved toward its offset end. The relative positions of the guide members and collectors are such that when the guide members are in engagement with the sides of the housing the collectors will be directly below the housing slots, so that when the guide members are moved inwardly along the housing the collectors will enter the slots in the inclined portion of the housing and engage the conductors.
