EDITORIAL NOTE: Each year February is Black History Month, but this year we will also mark the 50th anniversary of the Civil Rights Act of 1964. In 1896, Woods created a system for controlling electrical lights in theaters, known as the "safety dimmer,"[36][22][37] which was economical, safe, and efficient, saving 40% of electricity use. The third and final component of Woods induction telegraphy requires a mechanism for using the coupled inductors to transmit, as well as receive, an electrical communication signal. So where does Granville Woods fit into the pantheon of inventors? How did Granville Woods improve the telegraph? How did the telephone different from the telegraph? above each proper noun and com. [12] At times, he would refer to himself as an immigrant from Australia,[13] in the belief that he would be given more respect if people thought he was from a foreign country, as opposed to being an African American. Because inductors #1 and #2 are adjacent or coupled to each other, there is now a zone of mutual inductance. The relationship between electricity and magnetism which causes electromagnetic induction wasnt known until around 1830, primarily through the efforts of the famous British physicist, Michael Faraday. "Granville Woods was known as the 'Black Edison,'" Dr. Parris told the audience as he began his recap of historical figures. He made it possible for moving trains to have telegraphs.

Based on "telegraphony " Woods invented the induction telegraph in 1887. [29] Woods' patent built upon previous third rail systems which were used for light rails and increased the power for use on underground trains. One of his most important inventions was the "troller," a grooved metal wheel that allowed street cars (later known as "trolleys") to collect electric power from overhead wires. [20], In 1884, Woods received his first patent for a steam boiler furnace,[21] and in 1885, Woods patented an apparatus which was a combination of a telephone and a telegraph. This invention allowed moving trains to communicate with train stations which helped everyone know where trains were at all times. by transporting commuters without crowding city streets. In 1888, Woods developed a system that helped conduct lines and overhead electric railroads. But were going to use the earlier version of Woods induction telegraphy described in the 915 patent because its much easier to understand from the drawings of this patent how the electromagnetic induction and coupled inductor components work in induction telegraphy.
