Elijah McCoy is issued patent #129843 for an
“Improvement in Lubricators for Steam Engines”.
McCoy was the son of former slaves who escaped from Kentucky through the
Underground Railroad. His reputation on his multiple patented items was so
great that people would ask, when buying equipment, if it was “the real McCoy”
or an imitation. 50 of his patents dealt with lubricating machines.
In Booker
T. Washington’s 1909 book “The Story of the Negro”, he cited McCoy as having
produced more patents than any other black inventor up to that time.
