As a young man, McCoy went to Scotland to apprentice as a mechanical engineer. After returning to his family in Michigan, the best job he could get was as a oilman and fireman on a steam-powered locomotive. Using his expertise, McCoy solved a common problem faced by the railroad system during his time. He created an oil cup that allowed an engine to remain in motion and receive constant lubrication, as opposed to regularly stopping the train to manually lubricate it.
McCoy’s invention was such a success that when ordering the part people insisted that they receive McCoy’s lubricator and not an inferior substitute. Buyers began to ask for “the real McCoy,” popularizing the expression that is still used today!
