  • Patent number: 4667934
    Abstract: A three speed winch has two alternative inputs. The first input shifts the winch between first, second and third gear trains by successive reversals of the direction of an input member. The alternative input drives the winch at two different speeds responsive to rotation of an input member in opposite directions. The alternative input may be connected to drive the winch in either first or third gear so that the winch provides seven gear ratios. There are four pairs of gear ratios available by simple reversal of direction of an input, and the winch has three different ratios between the gear ratios of the different pairs.
