The first English patent under the category of washing machines was issued in 1691. A drawing of an early washing machine appeared in the January 1752 issue of "The Gentleman's Magazine", a British publication. Jacob Christian Schäffer's washing machine design was published 1767 in Germany. In 1782, Henry Sidgier issued a British patent for a rotating drum washer, and in the 1790s Edward Beetham sold numerous "patent washing mills" in England. One of the first innovations in washing machine technology was the use of enclosed containers or basins that had grooves, fingers, or paddles to help with the scrubbing and rubbing of the clothes. The person using the washer would use a stick to press and rotate the clothes along the textured sides of the basin or container, agitating the clothes to remove dirt and mud. This crude agitator technology was hand-powered, but still more effective than actually hand-washing the clothes.
