ABSTRACT:
A mirror assembly adapted to be rotatably mounted with respect to a support structure such as a wheeled vehicle of the class that includes trucks, tractors, large recreational vehicles, etc. A rotatable housing carries a mirror and there is a fixed mounting bold for supporting the housing. A motor is connected to the housing so as to rotate it when power is applied to the motor. A clutch is associated with the motor in order to preclude damage if power is applied to the motor but the housing is incapable of moving. The clutch includes two pairs of metallic spring washers which are of the Belleville type and which have concave faces. The two washers of each pair are in contact and are oriented in the same direction, so that there is a substantial area of metal-to-metal contact between the washers of each pair of washers. A lubricant such as graphite is interposed between the pairs of Belleville washers. When the motor is a high-speed electrical motor, there is included a transmission for affecting the rate at which the housing will rotate with respect to the mounting bolt when power is applied to the motor, such that the motor may rotate at a relatively high speed (e.g., 6,000 RPM) but the housing will rotate at a relatively low speed (i.e., 1/2 RPM).
