"Elijah Galloway patented, in 1829, the Feathered Paddle-wheel, in which the floats are mounted on axes, and are connected by rods with a common center, which is made to revolve eccentrically to the axis of the paddle-wheel. By this method, the floats are kept, while immersed, at right angles to the surface of the water. So long as the water is smooth, and the immersion constant, the gain is great." — Chambers, 1881

"The usual form of paddle-wheel, that is called the radial, in which the floats are fixed. It will be seen that a certain loss of power is involved, as the full force of the engine on the water is only experienced when the float is vertical, and as on entering and leaving the water the power is mainly devoted to respectively lifting and drawing down the vessel." — Chambers, 1881
