A short 1862 Scientific American article describing Turner and Robinson's patented machine for washing raw wool, which replaces hand stirring in tubs. An oval tub with a partition and rotating wheel circulates the wool in an alkali solution, and a slatted apron and pressing rollers lift it out and squeeze out the water. The article explains the parts of the engraved illustration and the advantages over hand washing, and gives the patent date of October 1, 1861.
