  • Patent number: 4145899
    Abstract: A new structural design for a washing basin within a laundry machine wherein independently pivoting washing bars are attached at suitable spacings to the basin. Said washing bars may be pivoted to any angle by means of the water flow. The toughness and flexibility of the washing bars disrupt the water flow, frictionally engage the items being washed and knock the items so as to enhance the cleaning process.The dependently pivoting washing bars have spherical bases which are pivotably positioned on the outer wall of the laundry basin by packing rings and sockets. The washing bars extend through soft water proofing washers protecting caps on the inner surface of the basin wall. When a bar is struck by the rotating water, the spherical base may freely rotate within the socket permitting the bar to rotate so as to disrupt the water flow and to frictionally engage the items being washed.
