"A ball-bearing hub with outward cups. The hub-shell H is turned out of mild steel, and the cups C are forced into the ends of the hub-shell and soldered thereto. A thin washer W is then spun into the end, for the purpose of retaining oil, and a thin internal tube T unites the two cups, and guides the oil fed in at the middle of the hub to the balls. The projecting flanges S are for the attachment of the tangent spokes used to build the hub into the wheel. The spindle A has the two cones screwed on it, one C, against the shoulder, the other C, adjustable. The-spindle ends are passed through the back-fork ends and are there adjusted in position by the chain-tension adjusters. After adjustments the nuts N clamp the spindle securely between the fork-ends. The chain-wheel or free-wheel clutch is screwed on the end of the hub-shell with a right-hand thread." — The Encyclopedia Britannica, 1910

"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
