Elijah McCoy
Elijah J. McCoy (May 2, 1844 – October 10, 1929) was a Canadian-American engineer of African-American descent who invented lubrication systems for steam engines. Born free on the Ontario shore of Lake Erie to parents who fled enslavement in Kentucky, he traveled to the United States as a young child when his family returned in 1847, becoming a U.S. resident and citizen. His inventions and accomplishments were honored in 2012 when the United States Patent and Trademark Office named its first regional office, in Detroit, Michigan, the "Elijah J. McCoy Midwest Regional Patent Office". Early life Elijah McCoy was born in 1844 in Colchester, Ontario, to George and Mildred Goins McCoy. At the time, they were fugitive slaves who had escaped from Kentucky to Ontario via helpers through the Underground Railroad. George and Mildred arrived in Colchester Township, Essex County, in what was then called Upper Canada in 1837 via Detroit. Elijah McCoy had eleven siblings. Ten of the ...

Colchester, Ontario
Colchester is a community and unincorporated place in Southwestern Ontario, the southernmost settlement on mainland Canada, and the southernmost point with the exception of Point Pelee National Park. It is located on the north shore of Lake Erie, approximately south of the town of Harrow. Colchester was formerly part of the Township of Colchester South and is now a part of the amalgamated Town of Essex within the County of Essex. Colchester shares its postal code with Harrow as N0R 1G0. Europeans began to settle in Colchester in the 18th century. Many United Empire Loyalists leaving the United States around the time of the American Revolutionary War were given land grants in Colchester. Some of names of these pioneers can still be found today in the names of residents throughout the region including: Snider, Huffman, Ferris, Hutchins, Iler, McCormick, Quick, and Tofflemire. One such Loyalist was John Snider of Pennsylvania. In 1798 Snider was given Lot 82 along the lakefront ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fugitive Slave
In the United States, fugitive slaves or runaway slaves were terms used in the 18th and 19th century to describe people who fled slavery. The term also refers to the federal Fugitive Slave Acts of 1793 and 1850. Such people are also called freedom seekers to avoid implying that the slave had committed a crime and that the slaveholder was the injured party. Generally, they tried to reach states or territories where slavery was banned, including Canada, or, until 1821, Spanish Florida. Most slave law tried to control slave travel by requiring them to carry official passes if traveling without a master. Passage of the Fugitive Slave Act of 1850 increased penalties against runaway slaves and those who aided them. Because of this, some freedom seekers left the United States altogether, traveling to Canada or Mexico. Approximately 100,000 American slaves escaped to freedom. Laws Beginning in 1643, the slave laws were enacted in Colonial America, initially among the New England Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michigan Department Of Labor And Economic Opportunity
The Michigan Department of Labor and Economic Opportunity (LEO) is a principal department of the State of Michigan. History Background Two previous principal departments of Michigan existed that focused on job training, the Department of Labor and the Michigan Department of Career Development. Department of Talent and Economic Development On December 18, 2014, Governor Rick Snyder used his constitutional authority to reorganize the executive branch of government to create the Michigan Department of Talent and Economic Development (TED). The Michigan Economic Development Corporation (MEDC) and Michigan Strategic Fund were scheduled to be transferred into the new department. A new agency, the Talent Investment Agency (TIA), was also set to be started concurrently with the department. The Michigan Strategic Fund would take over the State Land Bank Fast Track Authority from the Michigan State Housing Development Authority. The Michigan Department of Talent and Economic Development ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Transport
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles ( rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement Lubricator
An automatic lubricator is a device fitted to a steam engine to supply lubricating oil to the cylinders and, sometimes, the bearings and axle box mountings as well. There are various types of automatic lubricator, which include various designs of displacement, hydrostatic and mechanical lubricators. Displacement lubricator Ramsbottom type The displacement lubricator was introduced in the United Kingdom in 1860 by John Ramsbottom. It operates by allowing steam to enter a closed vessel containing oil. After condensing, the water sinks to the bottom of the vessel, causing the oil to rise and overflow into delivery pipes. The oil from the delivery pipes is introduced into the steam pipe, where it is atomised and carried to the valves and cylinders. In early applications in steam locomotives, either two displacement lubricators (one for each cylinder) would be positioned at the front of the boiler near the valves, often on either side of the smokebox or one lubricator would be ...

Michigan Central Railroad
The Michigan Central Railroad (reporting mark MC) was originally incorporated in 1846 to establish rail service between Detroit, Michigan, and St. Joseph, Michigan. The railroad later operated in the states of Michigan, Indiana, and Illinois in the United States and the province of Ontario in Canada. After about 1867 the railroad was controlled by the New York Central Railroad, which later became part of Penn Central and then Conrail. After the 1998 Conrail breakup, Norfolk Southern Railway now owns much of the former Michigan Central trackage. At the end of 1925, MC operated of road and of track; that year it reported 4,304,000 net ton-miles of revenue freight and 600 million passenger-miles.

Oiler (occupation)
An oiler (also known as a "greaser") is a worker whose main job is to oil machinery. In previous eras there were oiler positions in various industries, including maritime work (naval and commercial), railroading, steelmaking, and mining. Today most such positions have been eliminated through technological change; lubrication tends to require less human intervention, so that workers seldom have oiling as a principal duty. In the days of ubiquitous plain bearings, oiling was often a job description in and of itself. Today, shipping is the economic segment that most thoroughly retains the notion of the oiler as a separate position. On a merchant ship, an oiler is an unlicensed rate of the engineering department. The position is of the junior rate in the engine room of a ship. The oiler is senior only to a wiper. Once a sufficient amount of sea time is acquired, the Oiler can apply to take a series of courses/examinations to become certified as an engineer. As a member of the engi ...

Tobacconist
A tobacconist, also called a tobacco shop, a tobacconist's shop or a smoke shop, is a retailer of tobacco products in various forms and the related accoutrements, such as pipes, lighters, matches, pipe cleaners, and pipe tampers. More specialized retailers might sell ashtrays, humidification devices, hygrometers, humidors, cigar cutters, and more. Books and magazines, especially ones related to tobacco are commonly offered. Items irrelevant to tobacco such as puzzles, games, figurines, hip flasks, walking sticks, and confectionery are sometimes sold. In the United States, a tobacconist shop is traditionally represented by a wooden Indian positioned nearby. Most retailers of tobacco sell other types of product; today supermarkets, in many countries with a special counter, are usually the main sellers of the common brands of cigarette. In the United Kingdom, a common combination in small corner shops has been a newsagent selling newspapers and magazines, as well as confe ...

Mechanical Engineering
Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches. Mechanical engineering requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Racial Segregation
Racial segregation is the systematic separation of people into race (human classification), racial or other Ethnicity, ethnic groups in daily life. Racial segregation can amount to the international crime of apartheid and a crimes against humanity, crime against humanity under the Statute of the International Criminal Court. Segregation can involve the wikt:spatial, spatial separation of the races, and mandatory use of different institutions, such as schools and hospitals by people of different races. Specifically, it may be applied to activities such as eating in restaurants, drinking from water fountains, using public toilets, attending schools, going to films, riding buses, renting or purchasing homes or renting hotel rooms. In addition, segregation often allows close contact between members of different racial or ethnic groups in social hierarchy, hierarchical situations, such as allowing a person of one race to work as a servant for a member of another race.
