ABSTRACT:
There is disclosed a drive apparatus for producing motion of a workpiece such as adjustment of a rear view mirror, comprising two drums arranged with their axis of rotations being relatively offset, the two drums being individually rotatable by means of a single controller in that the controller is attached to each drum such that it is off-center in only one of the vertical and horizontal directions, each drum controlling either vertical or horizontal motion of the workpiece. Also disclosed is a mirror head adapted for remote control and a compensator for Bowden cables comprising a hollow block adapted to receive and retain an outer cable of at least one Bowden cable, the block being mounted with a housing having an interior wall, shaft means passing through the block and acting on the interior wall, a first compression spring mounted on the shaft inside the block, a retaining device for holding the spring against axial movement relative to the block to allow for excessive cable tension, and a primary adjusting means for adjustment of primary cable tensions.
