White Motor Company
The White Motor Company was an American automobile, truck and bus manufacturer from 1900 until 1980. The company also produced bicycles, roller skates, automatic lathes, and sewing machines. Before World War II, the company was based in Cleveland, Ohio.
==History==
About 1898, Thomas H. White purchased a Locomobile steam car and found its boiler unreliable. His son, Rollin, set out to improve its design. Rollin White developed a form of water tube steam generator which consisted of a series of stacked coils with two novel features: the first was that the coils were all joined at the top of the unit, which allowed water to flow only when pumped, allowing control of the steam generation; the second was pulling steam from the lowest coil, closest to the fire, which allowed control of steam temperature. This second point was critical because the White steamer operated with superheated steam to take advantage of steam's properties at higher temperatures. Rollin White patented his steam generator, US patent 659,837 of 1900.
