Elijah J. McCoy was a Canadian-American inventor and engineer.
Background
Elijah J. McCoy was born on May 2, 1844 in Colchester, Ontario, Canada to George and Mildred (Goins) McCoy. They were fugitive slaves who had escaped from Kentucky to Canada via helpers through the Underground Railroad. Elijah McCoy had eleven siblings.
Education
Elijah McCoy was educated in black grammar schools of Colchester Township due to the 1850 Common Schools act which segregated the Upper Canada schools in 1850. At age 15, in 1859, Elijah McCoy was sent to Edinburgh, Scotland for an apprenticeship and studied mechanical engineering for five years.
Career
When Elijah McCoy arrived in Michigan, he could find work only as a fireman and oiler at the Michigan Central Railroad. In a home-based machine shop in Ypsilanti, Michigan McCoy also did more highly skilled work, such as developing improvements and inventions. He invented an automatic lubricator for oiling the steam engines of locomotives and ships, patenting it in 1872 as "Improvement in Lubricators for Steam-Engines"
Similar automatic oilers had been patented previously; one is the displacement lubricator, which had already attained widespread use and whose technological descendants continued to be widely used into the 20th century. Lubricators were a boon for railroads, as they enabled trains to run faster and more profitably with less need to stop for lubrication and maintenance.
McCoy continued to refine his devices and design new ones; 50 of his patents dealt with lubricating systems. After the turn of the century, he attracted notice among his black contemporaries. Booker T. Washington in Story of the Negro (1909) recognized him as having produced more patents than any other black inventor up to that time. This creativity gave McCoy an honored status in the black community that has persisted to this day. He continued to invent until late in life, obtaining as many as 57 patents. Most of these were related to lubrication, but others also included a folding ironing board and a lawn sprinkler. Lacking the capital with which to manufacture his lubricators in large numbers, he usually assigned his patent rights to his employers or sold them to investors. Lubricators with the McCoy name were not manufactured until 1920, near the end of his career. He formed the Elijah McCoy Manufacturing Company to produce his works.
Elijah McCoy died in the Eloise Infirmary in Nankin Township, now Westland, Michigan, on October 10, 1929, at the age of 85, after suffering injuries from a car accident
Historians have not agreed on the importance of McCoy's contribution to the field of lubrication. He is credited in some biographical sketches with revolutionizing the railroad or machine industries with his devices. Early twentieth-century lubrication literature barely mentions him; for example, his name is absent from E. L. Ahrons' Lubrication of Locomotives (1922), which does identify several other early pioneers and companies of the field.
This popular expression, typically meaning the real thing, has been associated with Elijah McCoy's oil-drip cup invention. One theory is that railroad engineers looking to avoid inferior copies would request it by name, and inquire if a locomotive was fitted with "the real McCoy system". This theory is mentioned in Elijah McCoy's biography at the National Inventors Hall of Fame.
Achievements
Elijah McCoy was notable for his 57 U. S. patents, most having to do with the lubrication of steam engines.
