Windlass Model
date: label: date made
content: 1922
notes: label: Description
content: The windlass drum is made of two sections of different diameters, which turn together as one piece. The rope is so attached that it winds upon one section of the drum as it unwinds from the other, the net lifting or lowering effect being the difference between the length of rope wound upon the drum and that unwound. By making the sections nearly alike in diameter a large mechanical advantage is secured without making the drum too slender for strength or the crank too long for convenience. This model was made for the US National Museum to demonstrate the elementary form of the differential hoist.
