A posser was historically a tool used for possing laundry by pumping the posser up and down on the laundry in the tub, or mixing laundry while hand washing it. Possers come in various forms; there is usually a vertical pole with a handle bar at the top but the base can be conical or domed. It has a double rim with a row of holes around the edge of the outer one. A similar tool with three (or more) legs was called a peggy-legs. Sometimes they took the form of a flat disk. As hand washing has been replaced by electric and mechanical washing machines, words and implements used for hand washing have fallen out of common use.
