African-American patents an ironing board

In 1892, a U.S. patent for a specialized “Ironing Board” was issued to the black American inventor, Sarah Boone, likely a former slave (No. 473,653). Her design featured a quite narrow padded board, curved to make it easier to iron sleeves. Numerous patents were issued before hers with similar titles. The first patent designated specifically as an “Ironing Table” was issued several decades earlier, in 1858, to W. Vandenburg and J. Harvey (No. 19,390).
