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.

Dual-handled winch

A low noise, self-locking winch with a cylindrical cable drum having a cable wound around its periphery. The drum is rotated by a drive wheel which is fixedly mounted on a drive shaft. A latch wheel, having a smooth outer periphery, is slidably mounted on the drive shaft adjacent the drive wheel with a layer of frictional braking material positioned therebetween such that axial pressure on the latch wheel with respect to the drive shaft causes the latch and drive wheels to rotate as a unit. A crank is threaded onto the end of the drive shaft adjacent the latch wheel so that rotation of the crank in a winding direction forces the latch wheel against the drive wheel to rotate the cable drum. A pivotally mounted latch lever is resiliently biased against the smooth outer periphery of the latch wheel in a manner that causes the latch lever to cam against the latch wheel as the drum rotates in an unwinding direction thereby locking the winch. Cable is unwound from the drum by rotating the handle to release the pressure of the latch wheel against the drive wheel thereby allowing the drive wheel to rotate free of the stationary latch wheel.
