Numéro d’image : 11828362
| Oliver Evans. Engraving of Oliver Evans (1755- 1819),American engineer. Evans was apprenticed to a wagon-maker,but by 1777 had invented a high- speed process for making textile machinery. Opening a flour mill with his brothers,Evans made improvements to the machinery so that only one person was needed to supervise the whole corn grinding process; this was the first automatic corn mill. He began developing high pressure steam engines,despite their tendency to explode. His amphibious dredging machine of 1804 was the first American steam-driven road vehicle. Evans' successful dealings as a merchant,in addition to his patent royalties,made him his fortune | |
