Elwood HaynesDied 13 Apr 1925 at age 67 (born 14 Oct 1857).American inventor who built one of the first successful gasoline-powered automobiles. In 1886, when natural gas was found in his hometown of Portland, Indiana, Haynes organized a company to supply it to the town. He devised a method to dehydrate the gas prior to its being pumped through the lines. Also in 1886, he invented a small vapor thermostat used on natural gas. In 1893, he purchased a gasoline engine and designed a "horseless carriage." When Haynes was searching for an alloy that would make a durable spark plug electrode, he invented stellite alloy, which invention is still contributing to society today. Harder than steel and resistant to corrosion, this metal now plays an important part in fabrication of aeronautical materials suitable for exploration of outer space. |
