notes: label: Description
content: This model was submitted to the U.S. Patent Office with the application for the patent issued to William A. Doble, of San Francisco, California, February 7, 1899, no. 619149.
label: Description
content: The model represents a small sector of the rotor of a water wheel to which are attached three buckets, which illustrate, generally, the characteristics of the modern [1930s] tangential water-wheel bucket, i. e., the notched lip, the splitter wedge, the curved face and back, and the method of attaching the buckets to the rotor.
label: Description
content: The feature of this particular bucket is the form of the curved faces, which are designed to disturb the jets of water as little as possible in any way except in the plane of the wheel’s rotation. The curves are developed upon the theory that the water moving at high velocity has a tendency to remain in one plane, called “kinetic stability”, so that the resultant angles of reaction caused by the reversing curves of the bucket faces are not a normal result of these curves but are divergent therefrom.
