Lubrication and locomotives
The English-speaking idiom “the real McCoy” is a phrase used by many to refer to an original verse a copy, but the story of its origin is not quite as well-known. Many believe it comes from Elijah McCoy. Born in 1844 in Canada, to parents who escaped slavery in America’s South, McCoy went on to file 57 U.S. patents in his lifetime.
One of McCoy’s inventions, the lubricating oil cup, allowed railroad steam engines to be lubricated without having to stop the train. Today, Klüber Lubrication, a business unit of Freudenberg, is one of the world’s leading manufacturers of specialty lubricants, and supplies materials to both automotive and railroad industries.
The wring mop
The original concept of the wring mop dates back to 1893 the year when Thomas W. Stewart, a Black man from Kalamazoo Michigan, patented the first mop with a wringing feature. According to U.S. patent 499402, Stewart developed a mop with a lever that compressed a spring to wring the mop head.
In the 130 years since Stewart’s invention, we have seen significant transformation in the concept he first designed. Today, for example, Freudenberg Home and Cleaning Solutions is known for its EasyWring® spin mop systems. This product has the same basic principle as what Stewart first developed but has evolved the concept into a product that includes a bucket with an integrated wringing mechanism.
