View of a cotton gin, located in a very small rural town.Wonderful for any wall in your home or office, or perhaps a greeting card. Many more wonderful works can be found in my various galleries, from photographs and photo art to digital creations and abstracts. Thanks for browsing, commenting and most of all for any purchases. Debbie Portwood :D..............................(Wikipedia - A cotton gin is a machine that quickly and easily separates cotton fibers from their seeds, allowing for much greater productivity than manual cotton separation. The fibers are processed into clothing or other cotton goods, and any undamaged seeds may be used to grow more cotton or to produce cottonseed oil and meal. Although simple handheld roller gins have been used in India and other countries since at least 500 AD, the first modern mechanical cotton gin was created by American inventor Eli Whitney in 1793, and patented in 1794. It used a combination of a wire screen and small wire hooks to pull the cotton through, while brushes continuously removed the loose cotton lint to prevent jams. Whitney's gin revolutionised the cotton industry in the United States, but also led to the growth of slavery in the xautomated cotton gins offer far higher productivity than their hand-powered forebears.....
RATIONAL - Cotton fibers are produced in the seed pods ("bolls") of the cotton plant; as a result, the fibers ("lint") in the bolls are interspersed with the seeds. The seeds must be removed from the lint to make the fibers usable. Historically, this task was performed by hand: production of cotton required hundreds of man-hours to separate the seeds from a useful amount of lint. Many simple seed-removing devices have been invented over the years, but until the invention of the cotton gin most required significant operator attention and worked on a small scale...........................
EARLY COTTON GINS - The earliest versions of the cotton gin consisted of a single roller made of iron or wood and a flat piece of stone or wood. Evidence for this type of gin has been found in Africa, Asia, and North America. The first documentation of the cotton gin by contemporary scholars is found in the fifth century AD, in the form of Buddhist paintings depicting a single-roller gin in the Ajanta Caves in western India. These early gins were difficult to use and required a great deal of skill. A narrow single roller was necessary to expel the seeds from the cotton without crushing the seeds. The design was similar to that of a metate, which was used to grind grain. The early history of the cotton gin is ambiguous, because archeologists likely mistook the cotton gin's parts for other tools. Between the 12th and 14th centuries, dual-roller gins appeared in India and China. The Indian version of the dual-roller gin was prevalent throughout the Mediterranean cotton trade by the 16th century. This mechanical device was, in some areas, driven by water power.............ELI WHITNEY'S PATENT - Eli Whitney's original cotton gin patent, dated March 14, 1794. The modern mechanical cotton gin was invented in the United States in 1793 by Eli Whitney (1765–1825). Whitney applied for a patent on October 28, 1793; the patent was granted on March 14, 1794, but was not validated until 1807. There is slight controversy over whether the idea of the modern cotton gin and its constituent elements are correctly attributed to Eli Whitney. The popular image of Whitney inventing the cotton gin is attributed to an article on the subject written in the early 1870s and later reprinted in 1910 in The Library of Southern Literature. In this article, the author claimed Catherine Littlefield Greene suggested to Whitney the use of a brush-like component instrumental in separating out the seeds and cotton. To date, Greene's role in the invention of the gin has not been verified independently. Whitney's cotton gin model was capable of cleaning 50 pounds (23 kg) of lint per day. The model consisted of a wooden cylinder surrounded by rows of slender spikes, which pulled the lint through the bars of a comb-like grid. The grids were closely spaced, preventing the seeds from passing through. Loose cotton was brushed off, preventing the mechanism from jamming. Many contemporary inventors attempted to develop a design that would process short staple cotton, and Hodgen Holmes, Robert Watkins, William Longstreet, and John Murray had all been issued patents for improvements to the cotton gin by 1796. However, the evidence indicates Whitney did invent the saw gin, for which he is famous. Although he spent many years in court attempting to enforce his patent against planters who made unauthorized copies, a change in patent law ultimately made his claim legally enforceable – too late for him to make much money from the device in the single year remaining before the patent expired.
