Automobile
Inventions
The automobile gave women ample opportunity for invention. In 1923, of the 345 inventions listed under "Transportation" in the Women's Bureau Bulletin No.28, about half were related to automobiles and another 25 concerned traffic signals and turn indicators. Among these inventions were a carburetor, a clutch mechanism, an electric engine starter, and a starting mechanism. During the 1930s, Helen Blair Bartlett developed new insulations for spark plugs. A geologist by training, her knowledge of petrology and mineralogy was critical in the development of innovative uses of alumina ceramics. |
