Rear view safety mirror
First Claim
1. In a rear view mirror of the type having bracket means for attachment to a vehicle, a planar mirror element, support means movably mounted on said bracket means for supporting said mirror element, said mirror element having a reflecting face and a rear face, the improvement comprising:
- said mirror element having an aperture therethrough, a rotary electric motor mounted on said support means adjacent said rear face, said electric motor having a housing, a field winding fixedly carried in said housing, said winding having a central axis, an armature,means mounting said armature in said housing for rotation about said central axis and movement along said axis between a first and second position with said winding surrounding at least a portion of said armature when said armature is in said second position,a shaft having one end connected to said armature, said shaft extending along said central axis and through said aperture in said mirror element, said shaft having its other end located adjacent said reflecting face of said mirror element,wiper means mounted on said other end of said shaft, said shaft and wiper means being rotatable and movable with said armature from said first toward said second position so that said wiper means will be pressed against said reflecting face of said mirror element,means for delivering electric current to said motor whereby a magnetic field will be established through said winding and armature to cause rotation of said armature and movement thereof from said first toward said second position to press said wiper means against said reflecting face of said mirror element.

Abstract
A rear view safety mirror is provided with an aperture through the mirror element through which extends a drive shaft for a wiper blade; the drive shaft is connected to the rotary armature of an electric motor which is mounted on the support bracket of the mirror in the rear portion thereof; the armature of the electric motor is mounted so as to be axially movable so that when the motor is supplied with direct current, the armature will shift its position to press the wiper element against the surface of the mirror during rotation thereof; a heating element is also provided in the housing of the mirror to maintain the mirror'"'"'s surface free of ice and snow during inclement weather.
