ABSTRACT:
An automatic ratchet reversal device actuated by any reversible rotatable motor is disclosed. A rotatable force applied by a motor in one direction causes a linkage means to reciprocate once to actuate a ratchet pawl for one-direction ratcheting. Reversal of the rotatable motor causes the linkage means to reciprocate once again in the opposite direction thus acutating a ratchet pawl in the opposite direction effecting the desired reversed ratcheting.
