Due to the immense heat generated by these new engines, a more viscous lubricant His most elaborate innovation, however, was the graphite lubricator, designed for “superheater” locomotive engines, which he patented in 1915, when he was 72 years old. His 1882 hydrostatic lubricator for locomotive engines, as well as his designs for ship engines, made a significant impact on the transport industry in the late 19th century. He alsoĬontinued to design new lubrication devices for a variety of mechanical engines. He soon found work instructing mechanical engineers on the proper installation of his lubricator, and consulting with manufacturers such as the Detroit Lubricator Company. The following year, McCoy married Mary E. The title “Improvement for Lubricators in Steam Engines.” The innovation spread rapidly through the railroad business, as it enabled locomotives to work without interruption. On 23 July 1872 he filed his first patent on the drip cup, registered under Process that delayed many passengers and freight trains.Īfter six years on the job, McCoy developed a device commonly known as an “oil-drip cup,” which administered a regulated amount of lubricant into the engine through a spigot. Locomotives had to stop frequently as firemen such as McCoy tended to the engine, squirting oil onto its axles, gears, and levers - a time-consuming Would quickly wear off, overheating and corroding the machinery and wasting tremendous amounts of fuel. Steam-powered engines of that era faced consistent mechanical problems as industrial lubricants \r\nImage: \u00a9 Government of Canada/McCurdy fonds/Archives of Ontario/I0024851.\r\n Career and Mechanical InnovationĮlijah McCoy had difficulty finding a job upon his return to Canada and instead found work in Ypsilanti, Michigan, as a fireman for the Michigan Central Railroad. In our public poll, James Watt was voted the eighth most popular Scottish scientist from the past.Park House in Colchester South in Ontario was a refuge for those escaping slavery in the 1800's. James Watt died in 1819 in Heathfield, near Birmingham, aged 83. He married Ann in 1776 and had a son and a daughter, who died of consumption before their father's death. Watt's first wife, Margaret, died in childbirth in 1773, leaving him with two young children. He was a fellow of the Royal Society of Edinburgh and the Royal Society of London, and became a Foreign Associate of the French Academy of Sciences. His achievements were recognised by fellow scientists. Watt continued to make improvements to steam engines, and patented other important inventions, such as the rotary engine and a steam locomotive. Watt and Boulton became leading figures in the Industrial Revolution. The Boulton
