Brass spinning patentIn 1851, the first U.S. patent for brass spinning was issued to H.W. Hayden in Waterbury, Connecticut (No. 8589). His invention was for machinery that could make kettles and similar articles from discs of metal. A disc was mounted in a chuck that rotated at a uniform speed. A tool then pressed against the metal and shaped it to a die. |
