Abstract

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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 245 words
A hand-held mechanical device adapted for removing snow, ice, mud and other caked detritus from a motor vehicle windshield; the device comprising a housing of generally onepiece construction having a hollow pistol-like handle portion for gripping and another hollow portion connected thereto and extending therefrom generally at a right angle to said hollow handle portion; bearing means removably secured to the forward end of said other hollow portion of said housing and having a sleeve element forming a central bearing bore; a driving shaft extending from the forward end of said other hollow portion and being slidable supported by said central bearing bore of said sleeve element; a blade secured to said driving shaft and being formed of a resilient rubber-like material; electric motor means within said handle portion of said housing, a rotatable shaft extending from the motor means, a disc mounted for rotation by the rotatable shaft, a connecting rod means connecting the disc to the driving shaft, one end of the rod being pivotably connected to said driving shaft, the other end of the rod being pivotably connected eccentrically to the rotatable disc, whereby upon rotation of the disc by said motor means, the driving shaft is driven in a reciprocating manner; an electrical heating coil embedded in the blade generally adjacent the edge thereof and in parallel electrical circuit connection with the electric motor means, and means for supplying electrical power to said motor means and heating coil for operating same.
