  • Ramped scrubbing vanes for auger agitator
    Patent number: 4048820
    Abstract: A washer agitator with an oscillating skirt portion below an upper, unidirectionally-rotating auger agitator portion has scrubbing vanes on the skirt ramped on one side so that the fabric such as clothing being washed is driven by the scrubbing vanes in a direction opposite to the direction of orbital fabric movement induced by the rotating auger, thereby minimizing tangling of the fabric during the washing cycle while optimizing roll-over.
