Cotton Picker
A cotton picker is either a machine that harvests cotton, or a person who picks ripe cotton fibre from the plants. The machine is also referred to as a cotton harvester. History In many societies, like America, slave and serf labor was utilized to pick the cotton, increasing the plantation owner's profit margins (See Trans-Atlantic Slave Trade). The first practical cotton picker was invented over a period of years beginning in the late 1920s by John Daniel Rust (1892–1954) with the later help of his brother Mack Rust. Other inventors had tried designs with a barbed spindle to twist cotton fibers onto the spindle and then pull the cotton from the boll, but these early designs were impractical because the spindle became clogged with cotton. Rust determined that a smooth, moist spindle could be used to strip the fibers from the boll without trapping them in the machinery. In 1933 John Rust received his first patent, and eventually, he and his brother owned forty-seven patents o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...

Allis-Chalmers
Allis-Chalmers was a U.S. manufacturer of machinery for various industries. Its business lines included agricultural equipment, construction equipment, power generation and power transmission equipment, and machinery for use in industrial settings such as factories, flour mills, sawmills, textile mills, steel mills, refineries, mines, and ore mills. The first Allis-Chalmers Company was formed in 1901 as an amalgamation of the Edward P. Allis Company (steam engines and mill equipment), Fraser & Chalmers (mining and ore milling equipment), the Gates Iron Works (rock and cement milling equipment), and the industrial business line of the Dickson Manufacturing Company (engines and compressors). It was reorganized in 1912 as the Allis-Chalmers Manufacturing Company. During the next 70 years its industrial machinery filled countless mills, mines, and factories around the world, and its brand gained fame among consumers mostly from its farm equipment business's orange tractors and s ...

A History Of Our Time
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Cotton Module Builder
The cotton module builder is a machine used in the harvest and processing of cotton. The module builder has helped to solve a logistical bottleneck by allowing cotton to be harvested quickly and compressed into large modules which are then covered and temporarily stored at the edge of the field. The modules are later loaded onto trucks and transported to a cotton gin for processing. History In 1971 the first experimental cotton module builder was designed and built by a team led by Professor Lambert H. Wilkes at Texas A&M University in cooperation with Cotton Incorporated.The Module Builder Cotton module builders have been in use since 1972. In the US today more than 90% of harvested cotton is compacted with module builders. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doffing Cylinder
A doffing cylinder, also called doffing roller or commonly just doffer is a component used in textile mills to remove fiber from the main cylinder of a card, on which the fibers have been straightened and aligned. The main cylinder of the card will have one or two doffers that comb and remove the fiber. The doffer is set with pins that hold the fiber, which is then removed by a comb or knife and fed into the next stage of production. Doffers are also used in cotton pickers and other machinery that handle fiber. Confusingly, the word doffer (meaning something that takes off, as in "doff your hat") is also used for mill workers whose job it is to remove full bobbins or pirns holding spun fiber and replace them with empty bobbins or pirns. In modern mills, a machine called a doffer may do this task. Early years Some people have given credit to Richard Arkwright for inventing the doffer, which was incorporated in his machine, but others consider that it was invented by James Hargrea ...

Spindle (tool)
In machine tools, a spindle is a rotating axis of the machine, which often has a shaft at its heart. The shaft itself is called a spindle, but also, in shop-floor practice, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself, but its bearings and anything attached to it (chuck, etc.). A machine tool may have several spindles, such as the headstock and tailstock spindles on a bench lathe. The main spindle is usually the biggest one. References to "the spindle" without further qualification imply the main spindle. Some machine tools that specialize in high-volume mass production have a group of 4, 6, or even more main spindles. These are called multispindle machines. For example, gang drills and many screw machines are multispindle machines. Although a bench lathe has more than one spindle (counting the tailstock), it is not called a multispindle machine; it has one main spindle. Examples of spindles include * On a la ...

Manual Labour
Manual labour (in Commonwealth English, manual labor in American English) or manual work is physical work done by humans, in contrast to labour by machines and working animals. It is most literally work done with the hands (the word ''manual'' coming from the Latin word for hand) and, by figurative extension, it is work done with any of the muscles and bones of the human body. For most of human prehistory and history, manual labour and its close cousin, animal labour, have been the primary ways that physical work has been accomplished. Mechanisation and automation, which reduce the need for human and animal labour in production, have existed for centuries, but it was only starting in the 18th and 19th centuries that they began to significantly expand and to change human culture. To be implemented, they require that sufficient technology exist and that its capital costs be justified by the amount of future wages that they will obviate. Semi-automation is an alternative to worke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Second Great Migration (African American)
In the context of the 20th-century history of the United States, the Second Great Migration was the migration of more than 5 million African Americans from the South to the Northeast, Midwest and West. It began in 1940, through World War II, and lasted until 1970. It was much larger and of a different character than the first Great Migration (1916–1940), where the migrants were mainly rural farmers from the South and only came to the Northeast and Midwest. In the Second Great Migration, not only the Northeast and Midwest continued to be the destination of more than 5 million African Americans, but also the West as well, where cities like Los Angeles, Oakland, Phoenix, Portland, and Seattle offered skilled jobs in the defense industry. Most of these migrants were already urban laborers who came from the cities of the South. In addition, African Americans were still treated with discrimination in parts of the country, and many sought to escape this. Urban settlement Comp ...

International Harvester Company
The International Harvester Company (often abbreviated by IHC, IH, or simply International ( colloq.)) was an American manufacturer of agricultural and construction equipment, automobiles, commercial trucks, lawn and garden products, household equipment, and more. It was formed from the 1902 merger of McCormick Harvesting Machine Company and Deering Harvester Company and three smaller manufactures: Milwaukee; Plano; and Warder, Bushnell, and Glessner (manufacturers of Champion brand). In the 1980s all divisions were sold off except for International Trucks, which changed its parent company name to Navistar International (NYSE: NAV). Its brands included McCormick, Deering, and later McCormick-Deering, as well as International. Along with the Farmall and Cub Cadet tractors, International was also known for the Scout and Travelall vehicle nameplates. Given its monumental importance to the building of rural communities the brand continues to have a massive cult following. The ...

Slavery In The United States
The legal institution of human chattel slavery, comprising the enslavement primarily of Africans and African Americans, was prevalent in the United States of America from its founding in 1776 until 1865, predominantly in the South. Slavery was established throughout European colonization in the Americas. From 1526, during early colonial days, it was practiced in what became Britain's colonies, including the Thirteen Colonies that formed the United States. Under the law, an enslaved person was treated as property that could be bought, sold, or given away. Slavery lasted in about half of U.S. states until abolition. In the decades after the end of Reconstruction, many of slavery's economic and social functions were continued through segregation, sharecropping, and convict leasing. By the time of the American Revolution (1775–1783), the status of enslaved people had been institutionalized as a racial caste associated with African ancestry. During and immediately ...
