  • Patent number: 5626158
    Abstract: Disclosed is a novel means for cleaning a paint roller brush. At the end of a painting operation, the painter sets the cylindrical applicator portion of the roller into a cradle having slots located at the ends for supporting the applicator axle at a central elevation which allows the applicator to free wheel, or spin. The roller handle is then brought around to rest in an opening located in the handle portion of the present invention and is rigidly held there during the cleansing operation. The painter then attaches a fluid source to a nozzle assembly slidably attached to rails located along the cradle wall. The pressurized fluid exits the nozzle through a plurality of spray jets onto the applicator at such an angle as to cause it to spin. The painter reciprocally moves the spray the entire length of the applicator until clean. The spin thereby centrifugally displaces the back wash, leaving the applicator relatively dry.
