See also:ELI See also:WHITNEY (1765-1825)
, See also:American inventor, was See also:born on a See also:farm in See also:Westboro, See also:Massachusetts, on the 8th of See also:December 1765
.
He exhibited unusual See also:mechanical ability at an See also:early See also:age and earned a considerable See also:part of his expenses at Yale See also:College, where he graduated in 1792
.
He soon went to See also:Savannah, See also:Georgia, expecting to secure a position as a teacher, but was disappointed, and accepted the invitation of Mrs See also:Nathanael See also:Greene, the widow of the Revolutionary See also:general, to spend some See also:time on her See also:plantation on the Savannah See also:river, while deciding upon his future course
.
The construction by See also:Whitney of several ingenious See also:household contrivances led Mrs Greene to introduce him to some gentlemen who were discussing the desirability of a See also:machine to See also:separate the See also:short See also:staple upland See also:cotton from its seeds, See also:work which was then done by See also:hand at the See also:rate of a See also:pound of See also:lint a See also:day
.
In a few See also:weeks Whitney produced a See also:model, consisting of a wooden See also:cylinder encircled by rows of slender spikes set See also:half an See also:inch apart, which extended between the bars of a grid set so closely together that the seeds could not pass, but the lint was pulled through by the revolving spikes; a revolving See also:brush cleaned the spikes, and the See also:seed See also:fell into another compartment
.
The machine was worked by hand and could clean 50 lb of lint a day
.
The model seems to have been stolen, but another was constructed and a patent was granted on the 14th of See also: The See also:financial returns in Georgia cannot be ascertained . The legislature of See also:South Carolina voted $50,000 for the rights for that See also:state, while See also:North Carolina levied a license tax for five years, from which about $3o,000 was realized . See also:Tennessee paid, perhaps, $10,000.1 Meanwhile Whitney, disgusted with the struggle, began the manufacture of See also:fire-arms near New Haven (1798) and secured profitable See also:government contracts; he introduced in this factory See also:division of labour and standardized parts . Although the See also:modern gin has been much enlarged and improved, the essential features are the same as in Whitney's first model, and the invention profoundly influenced American See also:industrial, economic and social See also:history .
