Elijah McCoy（1843～1929）, a mechanical engineer, worked with locomotives and parts of locomotives. He invented a self-lubricating（自动加油）machine. The machine makes it possible for machines to lubricate themselves—to put oil on themselves, that is.

　　McCoy, a black man who was the son of slaves, called his first lubricating machine a“lubricator cup”. The cup allowed small drops of oil to drip continuously onto the moving parts, keeping the machine in good running order.

　　As slaves, McCoy’s parents lived in Kentucky. They fled from the United States and settled in Canada. Elijah was born in Colchester, Ontario, Canada, in 184(3) McCoy’s father worked hard in Canada. With pride, he sent Elijah to Edinburgh, Scotland. The boy was then fifteen years old. Elijah McCoy attended a school of engineering in Edinburgh. He studied mechanical engineering. Upon completing his studies, McCoy returned to the United States. No one wanted to hire a black man as a mechanical engineer. Finally McCoy took a job as a fireman for the Michigan Central Railroad.

　　McCoy shoveled（铲）coal and oiled the moving parts of the locomotive. This was a hard job for a mechanical engineer! But McCoy gave some thoughts to his work. Suddenly he had an idea. Why couldn’t a train oil itself? McCoy then invented the self-lubricating machine.

　　Perhaps you have heard the expression“the real McCoy”. The expression is applied（应用）to high quality tools and machines. Railroad men who used the self-lubricating machine boasted（自夸）of having“the real McCoy”.
