Who invented the oil cup?
McCoy
It was in this line of work that he developed his first major inventions. After studying the inefficiencies inherent in the existing system of oiling axles, McCoy invented a lubricating cup that distributed oil evenly over the engine’s moving parts.
Who made the self lubricating steam engine?
The U.S. Patent and Trademark office in Detroit bears the name of Elijah McCoy, a pioneering African-American inventor. McCoy was born in the mid-1840s, nearly 170 years before the office opened. McCoy had more than 50 patents to his name. He’s best known for inventing an automatic lubricator that was used on trains.
When was the lubricating cup invented?
1872
If they stopped too often, freight and passengers would be delayed. McCoy invented a lubricating cup that oiled engine parts as the train was moving. He secured a patent for it in 1872 and steadily improved it over time.
What did Elijah McCoy invent?
automatic lubricator
Invention: In 1872, McCoy developed an automatic lubricator that spread oil evenly over a train’s engine while it was still moving. The invention allowed trains to run for long periods of time without stopping, which saved both time and money. McCoy was a prolific inventor, securing dozens of patents in his lifetime.
Did a black man invent the steam engine?
Granville T. Woods earned his first patent in 1884 for a steam boiler. He also invented a system for railroad braking, electric railroad systems, and devices to improve the telephone and telegraph. The telephone and telegraph patents were bought by Alexander Graham Bell’s company.
When did Elijah McCoy make the lubricating cup?
In an effort to improve efficiency and eliminate the frequent stopping necessary for lubrication of the train, McCoy set out to create a method of automating the task. In 1872 he developed a “lubricating cup” that could automatically drip oil when and where needed.
Where was the lubricating cup invented?
Called the lubricating cup, or lubricating oil cup, he patented it in 1872. In 1882, McCoy settled in Detroit, Michigan, where he worked as a mechanical consultant to many engineering firms, establishing his own company, the Elijah McCoy Manufacturing Company, in 1920.
