单词 | sickels, frederick ellsworth |
释义 | Sickels, Frederick EllsworthSickels, Frederick Ellsworth(1819–95) engineer, inventor; born near Camden, N.J. A physician's son, he had a fascination with railroads and went to work as a rodman for the Harlem Railroad at age 16. In 1841 he perfected his first invention, a cut-off for steam engines. His steam-powered steering apparatus for ships was not, however, a success; it worked, but no one would buy it. He migrated west after the Civil War, building railroads and bridges, and later became chief engineer for the waterworks in Kansas City, Mo. |
