<p>COMBINED OSCILLATING AND UNIDIRECTIONAL AGITATOR FOR AUTOMATIC WASHER 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.</p> |
