ABSTRACT:
A hand-held mechanized electrically heated windshield cleaner for removing snow, ice and other material from a motor vehicle windshield includes a hollow pistol-like housing having a gripping portion and a barrel portion extending at right angles thereto. A bearing member at the front of the barrel portion slidably supports an outwardly extending driving shaft. A scraper blade of resilient rubber-like material is secured to the outer end of the shaft. An electric motor in the gripping portion reciprocatingly drives the shaft through an arrangement including a disk rotated by the motor and eccentrically connected to the shaft by means of a connecting rod. An electric heating coil is provided in the blade adjacent the edge thereof. The heating coil and motor are energized by an electric cable adapted to be plugged into the vehicle cigarette lighter socket.
