All Aboard!: Elijah McCoy's Steam Engine
GREAT IDEA SERIES Inventor No. 2
The year was 1860, and Elijah McCoy, the son of slaves, dreamed of becoming a mechanical engineer. He studied in Scotland, where he learned everything there was to know about engines, how to design them and how to build them. But when he came home to look for work at the Michigan Central Railroad, the only job Elijah could get was shoveling coal into a train's firebox! What Elijah lacked in opportunity, he more than made up for in ingenuity: he invented an oil cup that oiled the engine while the train was running!
For anyone who is fascinated by steam engines and the joy of invention, All Aboard! Elijah McCoy's Steam Engine, with its playful, informative text and lively illustrations, is a wonderful introduction to biography, to invention, and to the man whose mind was so full of ideas that he was able to create an oil cup that made train travel faster and safer for everyone.
