"We may compare currents by the quantities of a given electrolyte which they decompose in a given time. Faraday's voltameter is intended for this purpose. As compared with a galvanometer, the voltameter has the obvious disadvantage that it cannot measure a current at once, but only after the current has been flowing for some time." -Hazeltine, 1894

The Wimshurst Machine is an electrostatic device to generate high voltages. "It consists of two circular glass plates, mounted on a common spindle, and capable of rotation in opposite directions with equal speeds. Each plate carries twelve or sixteen strips of thin sheet-metal, fixed radially at regular intervals apart ... At the extremities of the horizontal diameter of the plates the main conductors are placed, insulated on glass or vulcanite pillars." -Hazeltine, 1894

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.
