Granville Woods patentIn 1903, Black American inventor, Granville T. Woods, was issued a U.S. patent for an "Electric Railway System." of the type that "current for the car-motor is taken from working contacts or conductors along the road bed." The object of Woods' invention was to "insure safety from shock at the working conductor or contacts, reduce leakage to a minimum, economize current in the operation of the system, and at the same time provide a system which can be easily constructed and perfectly controlled." He assigned the right to the General Electric Company of New York. Woods produced many inventions relating to railways. (No. 718,183) |
