Another business, the development of which is due in large measure to the inventions of a colored man, Elijah McCoy, is that of making automatic lubricators for machinery. Mr. McCoy is regarded as a pioneer inventor in that line. He completed and patented his first lubricating cup in 1872. Since then he has patented both in this country and abroad nearly fifty different inventions relating principally to the art of automatic lubrication machinery, but including also a considerable variety of other devices. His lubricating cup was at one time in quite general use on the locomotives of the leading railways of the Northwest, on the steamers of the Great Lakes, and in up-to-date factories throughout the country. He is still living in Detroit, Michigan, and still adding new inventions to his already lengthy list. In completing and patenting upwards of 50 different inventions Granville T. Woods, late of New York, appears to have surpassed every other colored inventor in the number and variety of his inventions. His inventive record began in 1884 in Cincinnati, Ohio, where he then resided, and continued without interruption for over a quarter of a century. He passed away January 30, 1910, in the city of New York, where he had carried on his business for several years immediately preceding. While his inventions relate principally to electricity, the list also includes such as a steam boiler furnace, the subject of his first patent, obtained in June, 1884; an amusement apparatus, December, 1899; an incubator, August, 1900; and automatic airbrakes, in 1902, 1903, and 1905. His inventions in telegraphy include several patents for transmitting messages between moving trains, also a number of other transmitters. He patented fifteen inventions for electric railways, and as many more various devices for electrical control and distribution. In the earlier stages of his career as a successful inventor he organized the Woods Electric Company, of Cincinnati, Ohio. This company took over by assignment many of his earlier patents; but as his reputation in the scientific world grew apace, and his inventions began to multiply in number and value, he seems to have found a ready market for them with some of the largest and most prosperous technical and scientific corporations in the United States. The official records of the United States Patent Office show that many of his patents were assigned to such companies as the General Electric Company, of New York, some to the Westinghouse Air Brake Company, of Pennsylvania, others to the American Bell Telephone Company, of Boston, and still others to the American Engineering Company, of New York. So far as the writer is aware there is no inventor of the colored race whose creative genius has covered quite so wide a field as that of Granville T. Woods, nor one whose achievements have attracted more universal attention and favorable comment from technical and scientific journals both in this country and abroad.
