ABSTRACT:
A ratcheting mechanism consisting of a ratchet housing having internal teeth, which surrounds a drive member and applies torque to a pawl mounted pivotally to said drive member, said pawl of said drive member having external teeth and being pivotable for ratcheting action against said ratchet housing internal teeth. The mechanism being reversible by the application of spring actuated force radially inward against either opposite distal end of said pawl, said spring being secured to an annularly configured control ring surrounding said drive and having means to directly engage and rotate said drive upon pawl reversal. The mechanism may be reversed and driven in either direction at any time simply by rotating the control ring in the direction desired to rotate the drive, followed by continued rotation of the control ring, or rotation of the housing member.
