Assigned to Edison Electric Light Co. - New York NY

This patent outlines the core idea of Edison's concept of DC power distribution. Implicit in this distribution system is that numerous generating stations would be required, in order to minimize transmission losses. Furthermore, because there is no easy and reliable way to change DC voltages—unlike AC power where transformers change voltages—if a machine or system needs a different voltage than others on the same block, then separate distribution systems are required. This inflexibility was fatal to the future of Edison's concept. The patent claims: "In a system of electrical distribution, the combination, with positive and negative service-conductors laid entirely around each block of a district, of feeding-conductors, each connected with one of said positive and negative conductors at points on opposite sides of each block electrically equidistant from the central station, substantially as set forth."
