8. A rotatablev tub for a washing machine adapted to receive liquid and fabrics to be washed, comprising a receptacle having a substantially cylindrical side wall with a lower edge and a generally horizontal bottom wall,mobile crushing plant spacing elements disposed about the outer periphery of said receptacle forsrigidly holding the lower edge of saidside wall and bottom wall in spaced relation to define an unobstructed circumferential Y discharge passage, means including the spacing means for securing said side and bottom walls together to provide a unitary structure, a container secured to said receptacle and havingits bottom wall spaced from the bottom wall of said receptaclfe to denne a sediment zone indirect communication with said passage, and an annular resilient sealing ring disposed between said spacing elements and the outer periphery of said receptacle and freely mounted with respect to said receptacle to seal the passage when said tub is rotating at relatively low speeds and to uncover said passage when said tub is rotated at relatively high speeds, said spacing elements being positioned to limit the outward movement of the sealing element when said tub is rotated.
9. Ina washing machine, the combination of a rotatable tub adapted to receive liquid and fabrics to be washed, said tub includinga side wall with alower endand a bottom wall, radially outwardly extending integral lugs disposed adjacent the lower end of said side wall and the outer periphery of said bottom wall, spacing elements disposed between said lugs for rigidly holding the lower end of said side wall and bottom wall in spaced relation to denne an unobstructed circumferential discharge passage, means for securing said lugs and spacing elements together to provide a unitary structure,rock mining equipment a container disposed within and secured to said tub and having its bottom wall spaced from the bottom wall of said tub to define a sediment zone in direct communication with said passage, means for rotating said tub, and an annular resilient sealing ring disposed between said spacing elernents and freely mounted with respect to said tub, radial lugs and the outer periphery of said tub to seal said passage when said tub is rotated below a predetermined speed and to uncover said passage when said tub is rotated above said speed, said spacing elements and lugs acting to limit and direct the movement of said sealing element when said tub is rotated.
