Abstract: An electrified pallet conveyor system for conveying appliances under electrical connection for testing, and which includes an electrical distribution contact shoe busway assembly. The busway consists of an elongated tubular housing having a continuous side access slot and a number of bus bar conductors mounted inside which coextend with the housing for conducting electricity. The electrical contact shoe assemblies are inserted at any desired location along the busway by inserting them into the access slot and twisting them 90.degree.. These contact shoe assemblies are prevented from further rotation by the confines of a closure strip which closes the side access slot of the housing off on opposite sides of the contact shoe assembly. A keying mechanism is also provided to prevent lateral movement of the contact shoe assembly in the bottom of the bus bar housing.

Abstract: A trolley rail section includes an elongated housing wherein a conductor junction assembly is retained by virtue of its connection to an elongated conductor within the same housing and with the cooperation of the conductor of an adjacent connected trolley rail section such that the unitary conductor and junction assembly may be assembled into or disassembled from their housing according to a method of assembly when the respective trolley rail section is disconnected from other trolley rail sections.
