  • Patent number: 5157551
    Abstract: The invention comprises a rear view mirror having a surrounding frame with a sleeve mounted vertically along one vertical edge of the frame. The sleeve has a slot and a screw is mounted within the sleeve with a pair of spiral grooves of opposite pitch connected together at their upper and lower edges to form an oscillating path. A ring is slidably mounted on the screw with a pin on the ring engaging the screw in one of the grooves. A motor drives the screw to cause the ring to oscillate vertically in the sleeve and a wiper has an arm connected to the ring through the slot in the sleeve, so that the oscillation of the ring on the screw causes the wiper to oscillate upward and downward on the mirror to wipe the mirror to remove rainfall.
