  • Patent number: 4137737
    Abstract: An agitator for a vertical-axis automatic clothes washing machine has a plurality of circumferentially spaced apart vanes extending upwardly from a skirt adapted to overlie the bottom wall of a tub or receptacle. A corresponding plurality of lobe-like cams projects outwardly and upwardly from at or near the periphery of the skirt in the alternate spaces between the vanes. Each cam extends approximately 5 to 15.degree. upwardly from the horizontal and is geometrically defined by two edges forming a segment of the surface of a cone co-axial with the agitator. The inner edge of each cam has the radius of the circular perimeter of the agitator skirt with which the edge is co-linear; the upper edge either has a somewhat smaller radius in a crescent-shaped configuration or has an irregular, double-lobe configuration.
