ABSTRACT:
A light-weight, corrosion-resistant, multiple engaging ratchet assembly comprising few, easily manufactured parts for simplified operation of pawls and ratchet teeth in a free-wheel drive gear ratchet assembly. An outer wheel includes a cavity to receive an inner wheel with a pawl ring or integral pawls. The pawls ride over ratchet teeth protruding from a circumferential surface on the outer wheel when the inner wheel and the outer wheel rotate in opposite directions. Turning the inner wheel in a second direction the same as the outer wheel direction of rotation brings the pawls into engagement with the ratchet teeth causing the inner wheel to drive the outer wheel.
