Black American patent |
Black American patent In 1884, black American inventor Willis Johnson of Cincinnati, Ohio, was issued a U.S. patent for an "Egg Beater" (No. 292,821). It was designed so that eggs, batter and similar ingredients used by bakers or confectioners could be mixed intimately efficiently. The image shows a top view, with one cylinder and hopper attached, with suitable mixing paddles (not seen in diagram) contained therein which are rotated by a shaft attached to a pulley and a hand crank. A second cylinder can be attached to the other end of the shaft so that production may be doubled. |
