ABSTRACT:
A torsion handle polisher in which a motor housing is provided with a pair of diametrically opposed, aligned outwardly extending torsion handles oriented in aligned relation and in perpendicular relation to the rotatable axis of the motor and polishing bonnet which is randomly orbited in relation to the motor housing. An arcuate slide arrangement is provided for actuating a motor switch enabling effective operation by left and right handed individuals with equal facility. The torsion handles can rotate with a limited degree of resistance to rotation to enable the polisher to readily move to various angular positions while the hands and arms of the operator of the polisher remain in the same angular relation to each other as the torsion handles rotate in relation to the motor housing. The torsion handles include embodiments with frictional resistance and resilient resistance which includes a spring loaded mechanism that will return the handle grip to a neutral or center position which allows the operator to pickup the polisher and place both hands on the handle grips without aligning one grip in relation to the other so that the operator always starts with both grips in the same position.
