Tubless washing machine

Claim 1

A vertical axis washing machine having an assembly of working parts for agitation of fabrics in a liquid during a washing cycle and centrifugal extraction of liquid from the fabrics during a draining cycle; a cabinet structure including a base enclosing the assembly of working parts; a mount including a support member secured to the assembly of working parts being adapted to move therewith during operation of the machine; means for supporting said assembly of working parts including a generally spherical bearing surface formed on said cabinet base and a generally spherical lower support surface on said mount formed complementary to the shape of said bearing surface on said base being slidably mounted therein for pivotally supporting said assembly of working parts; a combination tub/wash basket for receiving washing liquid and fabrics to be washed including a generally circular imperforate concave base having a drain opening at the center thereof and a generally cylindrical imperforate side wall portion extending upwardly from said base; a perforated divider member secured within the basket above the base dividing said basket to provide an upper fabrics retaining area for effecting washing action on the fabrics being washed and a lower basket drain area; a central shaft secured to said concave base of said basket extending downwardly therefrom being rotatably supported on said support member of said mount for rotation with said basket; an axially aligned sump area arranged at the lower end of said central shaft; a conduit in said central shaft extending from said drain opening to said axially aligned sump area for causing washing liquid to flow from said drain area to said sump area; pump means carried by said mount including a conduit connected to said sump area for draining liquid from said sump area; drive means on said mount including an electrically reversible motor for alternatively providing oscillatory motion and rotatable motion of the basket about its vertical axis; basket drive means including means rotatably mounted on said motor shaft operably connected to said central shaft for imparting oscillating movement to said basket during said washing cycle and for imparting rotational movement to said pump means during said draining cycle; pump drive means associated with said pump means for imparting rotational movement to said pump means; and clutch means operable between said basket drive means and said pump drive means for causing said motor to be selectively connected between said basket drive means and said pump drive means.
