ABSTRACT:
A mirror disposed within and protected by a housing that is itself mounted to accommodate major position adjustments rotates and tilts about vertically and horizontally disposed axes to provide minor position adjustments with respect to the mounting axis for the mirror housing. Separate reversible rotate and tilt motors disposed within the housing and controlled by remote switches power such minor positon adjustments. One top or bottom end of the mirror is associated with and interconnected to a bushing establishing one fixed control pivot for localizing rotation and tilting of the mirror, while the opposite end of the mirror may be moved to varied angular positions with respect to said fixed control pivot whereby the mirror is tilted about a horizontal axis. The rotate and tilt motors are variously mounted on the case or on the mirror itself and are interconnected by linkage means to the mirror or to an intermediate shaft in a manner providing movement for the mirror and housing or for the mirror with respect to the housing.
