Abstract
An assembly which involves a ratchet wheel adapted to be rotated by incremental steps to drive a shaft connected thereto. A rotatable pushbutton is mounted through a hole in the chassis and is connected to a rod to which a flexible pawl is mounted parallel to the rod. When the pushbutton is in one rotary position, inward pressure strokes on the pushbutton cause the pawl to engage teeth in one region of the ratchet wheel causing it to move in a clockwise direction. When the pushbutton is rotated 180.degree. to a second rotary position, each inward push on the pushbutton causes the pawl to engage respective teeth in another region of the wheel thereby moving the wheel incrementally one step in a counterclockwise direction.
