Black-American inventor holding many patents for the automatic lubrication of machinery. Born in Canada. While resident in Ypsilanti, Michigan, after two years of development, he received his first U.S. patent.
When McCoy’s second wife, Mary Eleanor Delaney (his first, Elizabeth Stewart, died after four years of marriage), complained that ironing clothes on uneven surfaces was difficult, McCoy set out to alleviate her frustrations. He invented a portable ironing board, much like the one still in use today. On 12 May 1874 he received a patent for it, pleasing his wife and hundreds of thousands of housewives since.
