ABSTRACT:
A two directional traversing mechanism uses a ratchet bar moved by an actuator to oscillate. Notches in the ratchet bar engage a pawl pivotally mounted to a piece of equipment so that the pawl and equipment move in the first direction. When the direction of the ratchet bar is reversed either the pawl is moved forward to an adjacent notch, or the pawl swings due to a biasing force such that when the ratchet bar again reverses direction, the ratchet bar causes the bar to pivot the pawl in a direction opposite the first direction. When the ratchet bar again operates in the reverse direction the pawl now engages with a notch of the ratchet bar and moves the equipment in the reverse direction.
