Non-Pneumatic Scaler

Abstract

A non-pneumatic scaler includes a linear motion gearbox and an electric motor in communication with the gearbox for selectively actuating it. An implement is removably coupled to the linear motion gearbox such that actuation of the gearbox causes the implement to oscillate. A housing contains the linear motion gearbox such that the implement extends partially outside the housing. A rechargeable battery is coupled to the housing for supplying power to the motor. The scaler includes a trigger for actuating the motor. Another input device is included for varying the rate of oscillation of the implement. One or more light emitting diodes may be mounted to the housing for illuminating a work area. The scaler may include a force transmitter that transfers the motor's force to cause the implement to rotate. A clutch may be manipulated to allow either the linear motion gearbox or the force transmitter to be selected.
