ABSTRACT:
A mechanically driven ratchet assembly which has a pawl gear attached to a rotationally biased shaft, a pawl assembly having a pawl tooth for engagement with a pawl gear, and a ratchet gear which alternately permits movement when driven by the pawl gear of the pawl assembly from a first position to a third position in which full rotation of the shaft, in the direction of the rotational bias, was permitted, and sequentially and alternatively permits rotation of the pawl assembly either from the first position to a second position where the pawl tooth remains engaged with the teeth of the pawl gear or to a third position where the pawl tooth is no longer engaged with the pawl gear.
