  • Patent number: 5460018
    Abstract: An automatic washer having an imperforate wash tub, a perforate wash basket disposed within the tub and rotatable about a vertical axis and a bottom plate disposed within the lower portion of the wash basket and mounted for wobbling motion. A motor is selectively interconnected with the basket and bottom plate for rotating the basket and the bottom plate together and for wobbling the bottom plate relative to the wash basket while the basket is held stationary such that the clothes items are agitated within the wash basket. A controlled rotation device is provided for driving the bottom plate in a wobbling motion while rotating the bottom plate, at a reduced rate, within the bottom of the wash basket. In a second embodiment, the wobble plate is supported and constrained to be driven in a wobbling motion while experiencing no rotation within the basket.

  • Patent number: 5437168
    Abstract: A top-loading horizontal axis automatic washer with improved accessibility to the wash basket interior and improved operating convenience of the basket doors. The washer cabinet is provided with an access opening extending partially along the front surface and top surface of the washer cabinet, providing the operator with improved access to the basket interior through an aligned tub opening and basket opening. A lid is provided on the cabinet top for selectively opening and closing the access opening. First and second door flaps are provided on the back and front edges, respectively, of the basket opening, serving as doors for selectively opening or closing the basket opening. The second door flap has an arc length approximately one-third the size of the first door flap. Both flaps are arranged so that, when opened, they are out of the path of loading and unloading clothes items from the basket.
