| Wikipedia: Windlass |
A windlass is an apparatus for moving heavy weights. Typically, a windlass consists of a horizontal cylinder (barrel), which is rotated by the turn of a crank or belt. A winch is affixed to one or both ends, and a cable or rope is wound around the winch, pulling a weight attached to the opposite end.
Windlasses are sometimes used on boats to raise the anchor as an alternative to a vertical capstan (see anchor windlass).
Windlasses can also be used to raise water from a well. The oldest description of a well windlass, a rotating wooden rod installed across the mouth of a well, is found in Isidore of Seville's (c. 560–636) Origenes (XX, 15, 1-3).[1] In the Late Middle Ages European crossbows employed a windlass as a cocking mechanism.
In a differential windlass, also called a Chinese windlass,[2][3][4] there are two coaxial drums of different diameters r and r'. The rope is wound onto one drum while it unwinds from the other, with a movable pulley hanging in the bight between the drums. Since each turn of the crank raises the pulley and attached weight by only 2π(r - r'), very large mechanical advantages can be obtained.
