Apr 2, 2014 · 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.

Jul 5, 2021 · What he came up with was an automatic lubricator that used steam pressure to pump oil where it was needed. McCoy patented his invention, known as an “oil-drip cup,” in 1872, and the device was an instant success.

Elijah J. McCoy (May 2, 1844 [A] – October 10, 1929) was a Canadian-American engineer of African-American descent who invented lubrication systems for steam engines.

Elijah McCoy was an inventor who developed the automatic lubricating cup which allowed trains to travel without delays to add oil to the axles and bearings.

In 1872, McCoy patented his invention, an automatic lubricator for steam engines, which was referred to as the lubricating cup, the oil-drip cup or simply “the lubricator.” The device used a small reservoir and a wick to deliver a steady flow of oil to the moving parts of the engine.

*On this date in 1872, Black inventor Elijah McCoy patented the Lubricator Cup. The device dripped small amounts of oil onto moving engine parts, saving businesses time and money—patent # 129,843 . It was used with steam engines.

Jul 18, 2022 · McCoy created a lubrication cup that evenly and automatically distributed oil across every moving part. Instead of frequently stopping for maintenance, locomotives could run for significantly longer. McCoy’s invention was an instant hit.

Elijah McCoy was the inventor of the lubricating oil cup that allowed railroad steam engines to be lubricated without stopping the train, saving time and money. McCoy was born in Colchester, Ontario, Canada on May 2, 1844.

May 2, 2017 · Then in 1872, McCoy invented and patented an automatic oiling device for the moving parts of steam locomotives, colloquially known as the “oil-drip cup.” “McCoy’s patented device was ...

McCoy quickly realized that his job could be done more efficiently, so he developed a lubricating cup that would automatically drip oil onto moving parts. McCoy received his first patent for the device, which enabled trains to travel continuously without having to stop for oiling.
