Abstract: A motorized floor stripper for stripping a floor covering away from a floor surface. The floor stripper has wheels and a motor mounted to a frame. An operator uses handles on the frame to move the floor stripper across the floor. The motor is coupled to an eccentric driver, which may be an eccentric cam. The eccentric driver is coupled in turn to a driven member. The driven member is coupled to the frame at a coupling point, and a working element such as a blade is attached to the driven member opposite the eccentric driver. When the motor drives the eccentric driver, the driven member drives the working element in a motion that depends on the configuration of the eccentric driver, the driven member, and the coupling point. By adjusting the location of the coupling point relative to the frame, the operator may adjust the motion of the working element to achieve a motion particularly suitable for removing the floor covering that is being stripped away from the floor.
