Abstract
Semi-automatic self-propelled side sweeping mode of operation is provided by any of three forms of rotating members supporting and propelling a nozzle body over a work surface. Two of these members are designed as load bearing brush rolls while cleaning or polishing, one is a smooth cylinder and brush, the other is a dense brush-covered roll. These nozzle propelling members are arranged as pairs in tandem or in dual to their direction of travel over a work surface. The third form may operate in additional modes. Its propelling members comprise at least one pair of wheels. Each wheel is coaxial to a brush roll and may rotate with the brush roll or may free-wheel until clutched to rotate with the brush roll through linkage responsive to operator urging.
An elongated handle is on the nozzle pointed in substantially the same direction as the nozzle propelling members. Operator urging of the handle, in a twisting action, will tilt the nozzle to increase the friction of one propelling member over that of the other on the work surface. This results in nozzle travel in the direction of rotation of the propelling member, in circular sweeps about the operator. Urging of the handle by twisting also may increase the speed of rotation of one nozzle propelling member by variable electrical switch to effect side sweeps in two directions when each propelling member is individually driven by an electrical motor.
