Patent ID: 6883784

Claim:
A manual boat winch hoist control mechanism, comprising: a handwheel with a central hub and a first threaded bore in said central hub; a housing having an interior providing environmental protection; a shaft having an outside threaded surface coupled at a first end to said first threaded bore, and having a friction engaging member, and passing from said housing interior to an exterior thereof; a friction thrust member located axially between said handwheel hub and said shaft friction engaging member providing a friction surface to frictionally engage said shaft friction engaging member, to thereby provide controllable slipping and locking up by change of pressure between said shaft friction engaging member and said friction thrust member; and a one-way roller clutch, fixed against motion relative to said housing and coupled to said friction thrust member, that provides radial support and limits rotation of said friction thrust member to a single rotary direction about a rotary axis.
