Granville T. Woods Black Edison
As a self taught inventor myself, I love hearing stories of other inventors who pulled themselves up by their bootstraps and simply figured everything out. Granville T. Woods, also known as the Black Edison, was that kind of person. He literally learned on the job. He made sure he had the knowledge to not only create his inventions, but bring them to market.
As a kid he had very little schooling, and as soon as he was able to he started working a variety of jobs, including work as a railroad engineer in a railroad machine shop, as an engineer on a British ship, in a steel mill, and as a railroad worker. While doing this, he decided to take courses in electricity and engineering at night school, along with some private tutoring.
His first patent was for an improved steam boiler furnace and later patents were mostly for electrical devices, including his second invention, an improved telephone transmitter. One of his most important inventions was a device that allowed trolley cars to collect electric power from overhead wires.
Granville T. Woods invented more than a dozen devices to improve electric railway cars and much more for controlling the flow of electricity. His most noted invention was a system for letting the engineer of a train know how close his train was to others. This device helped cut down accidents and collisions between trains.
Becoming an Engineer
In 1872, Granville T. Woods got a job as a fireman on the Danville and Southern railroad in Missouri, eventually becoming an engineer. He invested his spare time studying electronics. In 1874, he moved to Springfield, Illinois, and worked in a rolling mill. In 1878, he took a job aboard the Ironsides, a British steamer, and, within two years, became Chief Engineer of the steamer. Finally, his travels and experiences led him to settle in Cincinnati, Ohio, where he became the person most responsible for modernizing the railroad.
Patent for an Improved Steam-boiler Furnace
In 1888, Granville T. Woods developed a system for overhead electric conducting lines for railroads, which aided in the development of the overhead railroad system found in cities such as Chicago, St. Louis, and New York City. In his early thirties, he became interested in thermal power and steam-driven engines. And, in 1889, he filed his first patent for an improved steam-boiler furnace.
Patent For Train Communication
In 1887, he patented the Synchronous Multiplex Railway Telegraph, which allowed communications between train stations from moving trains. Granville T. Woods’ invention made it possible for trains to communicate with the station and with other trains so they knew exactly where they were at all times.
