Abstract: A power or manually operated winch mechanism for handling the running rigging lines of a sailing yacht. The winch includes a winding drum, operating in conjunction with a level wind mechanism. A special, manually operated line release clutch allows controlled release of line independently of the power or manual drive mechanisms of the winch, providing for quick release under emergency conditions as well as for a convenient, manually controlled release for sail control purposes. During line release by power or manual rotation of the winding drum, the line is tensioned by the level wind mechanism and thus positively drawn from the unwinding winch drum The arrangement enables lines to be automatically released from one winch and retrieved on a second winch, under a common control, as when tacking or resetting sails, without any physical line handling by crew members, with resulting improvement in the safety and convenience of the crew.

A brake is associated with said spool to prevent unwanted extension of said strap from said spool, when a weight is suspended by said strap. In a preferred embodiment a clutch is provided between the brake and the drive train, and the greater the weight supported by the spool the greater the braking force. An emergency lift and lower device is also provided in the event of a failure of the motor.

Abstract: A motor winch, which is suitable as a sheet or halyard winch (11) for sailing yachts, etc., has an integrated electric or hydraulic drive. The motor (52) is integrated into the winch in such a way that it is located within the winch body and in particular within the winch drum (16). The motor brings about rotation of the winch drum through a multistage gear located in the winch foot (22), optionally assisted by an epicyclic gear (54). A manual operation with a winch crank is made possible by a winch crank nut (32) in the winch head (29). The manual driving shaft is past the somewhat eccentrically positioned motor. A reverse rotation or veering function can be provided in which following the disconnection of the drum locking mechanism, the motor is rotated back in braking manner with a controlled speed.

Abstract: A winch includes a reversible electrical motor with output shaft which drives a drum through a drive mechanism with multiple sprockets and gears to take up and let out a cable. The output shaft is connected through a one-way bearing to a brake hub. The brake lining on a brake arm is spring biased into engagement with the hub and prevents reverse rotation of the output shaft unless an electrical switch actuator is moved to a reverse position, camming the brake arm out of braking relationship with the hub. The drive mechanism may also be powered manually in the forward direction. If free-wheeling of the drum is desired, a knob is rotated to disconnect a clutch in the drive mechanism.
