ABSTRACT:
A dual-handled manual winch has a ratchet wheel meshing constantly with a pawl and which is automatically frictionally locked to a drive pinion for the winch drum when the drum starts to overrun. The drive pinion is threaded into a drive shaft on the ends of which the handles are mounted in diametrically opposite relation and on which the ratchet wheel and a pair of friction washers are sleeved to be engaged between the pinion and the ratchet wheel, and between the ratchet wheel and a stop collar on the shaft, responsive to axial movement of the drive pinion in the shaft toward the ratchet wheel.
