ABSTRACT:
In a multi-speed winch which has automatic uncoupling of a first drive ratio when drive input is reversed, an actuator can have an uncoupling position or one in which the first drive ratio is engaged. The actuator is resiliently urged towards the latter position so that when released from a detent which holds it in the uncoupling position it is driven to adopt the engagement position. The operator of the winch therefore does not move the actuator to the engagement position but merely is provided with means for releasing it. Reversal of the drive input when the actuator is in the engagement position causes return of the actuator to the uncoupling position, against its resilient urging. The first drive ratio is usually a 1:1 drive.
