English Abstract




COMBINED OSCILLATING AND UNIDIRECTIONAL
AGITATOR FOR AUTOMATIC WASHER
ABSTRACT OF THE DISCLOSURE
Improved agitation means for use in a clothes washing machine of
the type in which an agitator is oscillated by means of a drive
mechanism to secure agitation of the clothes placed within the washing
machine. The present invention provides a first agitator element and
a second agitator element driven from a common driving source, the
second agitator element being provided with means to urge clothes
into a rollover pattern established by the coaction of the agitator
elements and thereby impart a highly efficient rollover motion to the
clothes. The first agitator element employs flexible vanes and is
preferably located below and coaxial to the second agitator element
which may be driven either intermittently, or continuously, in a
unidirectional rotary motion. Use of the flexible vanes tends to avoid
tangling of fabrics on the agitator, which might otherwise lead to
increased shaft torque, reduced rollover or an unbalanced load of
clothes.
