Description
Calhoun's patent has the following operational information: "When the machine is operated, one chain is detached, and the rubber is lifted out of its bed by the spiral springs. The water and soap are put in the tub, and the clothes distributed upon the wash-board. The rubber is then brought down by pressure on the lever, and the chain fastened to its place. A reciprocating motion backward and forward is then given to the rubber by the hand applied to the handle j of the lever. This movement is attended by a downward pressure of the lever, which is more or less powerful as the clothes may require severe or gentle treatment." (Patent Number 99,842)
