![]() ![]() He went on to open the Mars Works in Philadelphia, where he constructed steam engines and boilers for mills, steamboats, and factories. Evans also placed the cylinder and the crankshaft at the same end instead of at opposite ends, greatly reducing the overall weight.Įvans had hope for steam-powered land locomotion, but his ideas were ahead of his time. High-pressure was introduced into a cylinder, causing the piston to push down. Although James Watt had already invented the low-pressure steam-engine, Evans' idea was for a high-pressure engine. The final product was flour that was finer, drier, and easier to store.īy the early 1800s, Evans' attention turned to steam power. In his design, elevators moved grain vertically, conveyers pushed grain horizontally, and hoppers sifted and dried the flour. Looking for increased efficiency, Evans harnessed the energy of a water wheel and used shafts, gears, and belts to propel mill machinery. ![]() As a young man, Evans ran a flour mill with two of his brothers. Oliver Evans, one of America's pioneering inventors, created the high-pressure steam engine and advanced the milling industry by automating flour mills.īorn in Newport, Delaware, Evans was apprenticed to a wheelwright and wagon maker as a teenager. ![]() Apply for the Collegiate Inventors Competition Although many people seem to give Thomas Savery the credit for inventing the steam engine in 1698, it was actually invented much earlier than that in Alexandria in Ancient Greece.Leadership Intern Program (High School & College Students).National Inventors Hall of Fame NIHF_2C Site navigation ![]()
