"Langens arrangement is a somewhat similar combination, the cone being made into a bell with perforated top, the edges of the perforation being turned over inwards bb; the bell rests upon the cup aa, the turned over edge cc fitting into a water lute surrounding the central tube kkk, so that whilst the bell is lowered the furnace top is gastight or nearly so. By means of a pair of levers d, d and a counterpoise swung on a horizontal axle at r by means of a winch e, the bell can be raised so that the charge in the cup falls into the furnace, sliding down the inclined surface. Two safety valves x and fg are provided, the latter being ordinarily supported by the pressure of the gases, but falling by its own weight when the gas pressure is relieved by raising the bell, so as to close the top of the gas shaft, the turned-down edges of g fitting into the annular groove oo; h is a small manhole for the introduction of scrapers to clear out flue dust when required." — The Encyclopedia Britannica, 1893

"A still more common form, much used in drawing water from wells and loaded buckets from mines, is shown [here]. Instead of a wheel, we have here a winch, or handle, attached to the axle." —Quackenbos 1859

"Windlass.—The common windlass for drawing water is another modification of the wheel and axle. The winch, or crank, by which it is turned, is moved around by the hand, and there is no difference in the principle, whether a whole wheel is turned, or a single spoke. The winch, therefore, answers to the wheel, while the rope is taken up, and the weight raised by the axle, as already described." —Comstock, 1850

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.
