He also affected the industrial development of the United States , in manufacturing muskets but most of whitney's own guns parts do not in fact interchange. Nevertheless, Eli Whitney is a figure whose history is fascinating, and whose impact in New Haven can not be overstated. He translated the concept of interchangeable parts into a manufacturing system, giving birth to the Americanmass-production concept. Whitney saw that a machine to clean the seed from cotton could make the South prosperous and make its inventor rich. He set to work at once and within days had drawn a sketch to explain his idea; 10 days later he constructed a crude model that separated fiber from seed. By 1793 he designed and constructed a machine called the cotton gin, that quickly separated cotton seed from the shortstaple cotton fiber. The first cotton gin was a wooden box that spun around a drum and picked the cotton seed with wire hooks.Cotton Gin, machine used to separate the fibers of cotton from the seeds. Before the invention of the cotton gin, seeds had to be removed from cotton fibers by hand; this labor-intensive and time-consuming process made growing and harvesting cotton uneconomical. The cotton gin allowed the seeds to be removed mechanically and rapidly from the cotton fibers, making cotton production economical and leading to dramatic growth in the United States cotton industry. This expansion contributed to an increase of slave labor in the United States. Whitney's cotton gin, also called a saw gin, consisted of a cylinder to which a number of sawlike teeth were attached. As the cylinder revolved, the teeth passed through the closely spaced ribs of a fixed comb. When cotton was fed into the gin, the teeth caught the cotton fibers and pulled them through the comb. The seeds, which were too large to pass between the ribs, were left behind,( This principle, with virtually no modifications, is still employed in modern automatic saw gins used to process the bulk of the U.S. cotton crop).After perfecting his machine he filed an application for a patent on June 20, 1793; in February 1794 he deposited a model at the Patent Office, and on March 14 he received his patent. Whitney's gin brought the South prosperity.Whitney entered into partnership with the plantation manager, Phineas Miller, to manufacture cotton gins at New Haven, Connecticut. A disastrous factory fire prevented the partners from making enough gins to meet the demand, and manufacturers throughout the South began to copy the inventio...
