Powdered graphite is soft and greasy, and easily withstands high temperatures. However, because it is a powder rather than a liquid, it can clog an engine. Hayden cites a letter from a railroad superintendent: "We have found the McCoy Graphite Lubricator to be of considerable assistance in lubrication of locomotives equipped with superheaters.
In reviewing the life of this inventor, writers and essayists often note that railroad purchasing agents commonly insisted on buying "the real McCoy. Many of these authors assert that the phrase "real McCoy" passed out of the specialized world of railroad engineering and entered general usage, where it came to mean "the genuine article. While McCoy's inventions made millions of dollars, little of this money reached his pockets.
Lacking the capital with which to build his lubricators in large numbers, he sold many of his patent rights to well-heeled investors. In return, he was given only the modest sums that allowed him to continue his work.
McCoy received at least 72 patents during his lifetime, most of which dealt with lubricating devices, but retained ownership of only a few of them. A year later, he married Mary Eleanora Delaney.
This marriage lasted half a century, but did not produce children. The firm manufactured and sold his graphite lubricators, including an advanced version that also lubricated a railroad train's air brakes. Soon afterward, he and his wife, Mary, were involved in a traffic accident. Mary received injuries from which she never fully recovered, and which hastened her death.
She died in For McCoy, the end now approached as well. His health deteriorated and, in , he entered an infirmary. McCoy was remembered in Detroit long after his death. In , the city celebrated Elijah McCoy Day, as officials placed a historic marker at the site of his home. The city also named a street for him. These posthumous honors were modest, but they came a century after his invention of the lubricating cup, and demonstrated his enduring legacy.

Known as "Black Edison," Granville Woods was an African American inventor who made key contributions to the development of the telephone, streetcar and more. Garrett Morgan blazed a trail for African American inventors with his patents, including those for a hair-straightening product, a breathing device, a revamped sewing machine and an improved traffic signal.
George Washington Carver was an African American scientist and educator. Carver is famous for many inventions including a number of uses for the peanut. Lewis Howard Latimer was an inventor and draftsman best known for his contributions to the patenting of the light bulb and the telephone.
Frederick Jones was an inventor best known for the development of refrigeration equipment used to transport food and blood during World War II. But his most widely known legacy—the "real McCoy" phrase—is less certain. However, parallel mythologies surround a number of other figures of the late 19th and early 20th century.
MacKay and Co. Maybe the most generous interpretation is to say they were all the real thing.
