The cotton gin is a mechanical device that removes the seeds from cotton, a process that had previously been extremely labor-intensive. The word gin is short for engine. The cotton gin was a wooden drum stuck with hooks that pulled the cotton fibers through a mesh. The cotton seeds would not fit through the mesh and fell outside. Whitney occasionally told a story wherein he was pondering an improved method of seeding the cotton when he was inspired by observing a cat attempting to pull a chicken through a fence, and could only pull through some of the feathers.["citation needed]
A single cotton gin could generate up to 55 pounds (25 kg) of cleaned cotton daily. This contributed to the economic development of the "Southern states of the United States, a prime cotton growing area; some historians believe that this invention allowed for the "African slavery system in the Southern United States to become more sustainable at a critical point in its development.["citation needed]
Whitney received a patent (later numbered as X72) for his cotton gin on March 14, 1794, but it was not validated until 1807. Whitney and his partner, Miller, did not intend to sell the gins. Rather, like the proprietors of "grist and "sawmills, they expected to charge farmers for cleaning their cotton – two-fifths of the value, paid in cotton. Resentment at this scheme, the mechanical simplicity of the device and the primitive state of "patent law, made "infringement inevitable. Whitney and Miller could not build enough gins to meet demand, so gins from other makers found ready sale. Ultimately, patent infringement lawsuits consumed the profits and their cotton gin company went out of business in 1797. One oft-overlooked point is that there were drawbacks to Whitney's first design. There is significant evidence that the design flaws were solved by a plantation owner, "Catharine Littlefield Greene, wife of the "American Revolutionary War general "Nathanael Greene; Whitney gave her no public credit or recognition.
While the cotton gin did not earn Whitney the fortune he had hoped for, it did give him fame.
It has been argued by some historians that Whitney's cotton gin was an important if unintended cause of the American Civil War. After Whitney's invention, the "plantation slavery industry was rejuvenated, eventually culminating in the Civil War.
And the cotton gin transformed Southern agriculture and the national economy. Southern cotton found ready markets in Europe and in the burgeoning "textile mills of "New England. Cotton exports from the U.S. boomed after the cotton gin's appearance – from less than 500,000 pounds (230,000 kg) in 1793 to 93 million pounds (42,000,000 kg) by 1810. Cotton was a staple that could be stored for long periods and shipped long distances, unlike most agricultural products. It became the U.S.'s chief export, representing over half the value of U.S. exports from 1820 to 1860.
Paradoxically, the cotton gin, a labor-saving device, helped preserve "slavery in the U.S. Before the 1790s, slave labor was primarily employed in growing rice, tobacco, and "indigo, none of which were especially profitable any more. Neither was cotton, due to the difficulty of seed removal. But with the gin, growing cotton with slave labor became highly profitable – the chief source of wealth in the American South, and the basis of frontier settlement from "Georgia to Texas. ""King Cotton" became a dominant economic force, and slavery was sustained as a key institution of Southern society.
Eli Whitney has often been incorrectly credited with inventing the idea of interchangeable parts, which he championed for years as a maker of "muskets; however, the idea predated Whitney, and Whitney's role in it was one of promotion and popularizing, not invention. Successful implementation of the idea eluded Whitney until near the end of his life, occurring first in others' armories.
Attempts at interchangeability of parts can be traced back as far as the "Punic Wars through both archaeological remains of boats now in Museo Archeologico Baglio Anselmi and contemporary written accounts.["citation needed] In modern times the idea developed over decades among many people. An early leader was "Jean-Baptiste Vaquette de Gribeauval, an 18th-century French "artillerist who created a fair amount of "standardization of artillery pieces, although not true interchangeability of parts. He inspired others, including "Honoré Blanc and "Louis de Tousard, to work further on the idea, and on shoulder weapons as well as artillery. In the 19th century these efforts produced the "armory system," or "American system of manufacturing. Certain other New Englanders, including "Captain John H. Hall and "Simeon North, arrived at successful interchangeability before Whitney's armory did. The Whitney armory finally succeeded not long after his death in 1825.
The motives behind Whitney's acceptance of a contract to manufacture muskets in 1798 were mostly monetary. By the late 1790s, Whitney was on the verge of bankruptcy and the cotton gin litigation had left him deeply in "debt. His "New Haven cotton gin factory had burned to the ground, and litigation sapped his remaining resources. The "French Revolution had ignited new conflicts between Great Britain, France, and the United States. The new American government, realizing the need to prepare for war, began to rearm. The "War Department issued contracts for the manufacture of 10,000 muskets. Whitney, who had never made a gun in his life, obtained a contract in January 1798 to deliver 10,000 to 15,000 muskets in 1800. He had not mentioned interchangeable parts at that time. Ten months later, the Treasury Secretary, "Oliver Wolcott, Jr., sent him a "foreign pamphlet on arms manufacturing techniques," possibly one of Honoré Blanc's reports, after which Whitney first began to talk about interchangeability.
In May 1798, Congress voted for legislation that would use eight hundred thousand dollars in order to pay for small arms and cannons in case war with France erupted. They offered a 5,000 dollar incentive with an additional 5,000 dollars once that money was exhausted for the person that was able to accurately produce arms for the government. Because the cotton gin had not brought Whitney the rewards he believed he would get, he accepted the contract. Although the contract was for one year, Whitney did not deliver the arms until eight years later in 1809 using multiple excuses for the delay of such. Recently, historians have found that during 1801–1806, Whitney took the money and headed into South Carolina in order to profit from the cotton gin.
Although Whitney's demonstration of 1801 appeared to show the ingenuity of interchangeable parts, "Merritt Roe Smith concludes that Whitney's demonstration was "staged" and "duped government authorities" into believing that he had created interchangeable parts. The charade was only useful in order to gain more time and resources for the project but not to create interchangeable parts.
When the government complained that Whitney's price per musket compared unfavorably with those produced in government armories, Whitney was able to calculate an actual price per musket by including "fixed costs such as insurance and "machinery, which the government had not included. He thus made early contributions to both the concept of "cost accounting, and the concept of the "efficiency of private industry.
Machine tool historian Joseph W. Roe credited Whitney with inventing the first "milling machine circa 1818. Subsequent work by other historians (Woodbury; Smith; Muir; Battison [cited by Baida]) suggests that Whitney was among a group of contemporaries all developing milling machines at about the same time (1814 to 1818), and that the others were more important to the innovation than Whitney was. (The machine that excited Roe may not have been built until 1825, after Whitney's death.) Therefore, no one person can properly be described as the inventor of the milling machine.
Later life and legacy
Despite his humble origins, Whitney was keenly aware of the value of social and political connections. In building his arms business, he took full advantage of the access that his status as a Yale alumnus gave him to other well-placed graduates, such as "Oliver Wolcott, Jr., "Secretary of the Treasury (class of 1778), and "James Hillhouse, a New Haven developer and political leader.
His 1817 marriage to Henrietta Edwards, granddaughter of the famed "evangelist "Jonathan Edwards, daughter of "Pierpont Edwards, head of the Democratic Party in Connecticut, and first cousin of Yale's president, "Timothy Dwight, the state's leading "Federalist, further tied him to Connecticut's "ruling elite. In a business dependent on government contracts, such connections were essential to success.
Whitney died of "prostate cancer on January 8, 1825, in New Haven, Connecticut, just a month after his 59th birthday. He left a widow and his four children behind. During the course of his illness, he invented and constructed several devices to mechanically ease his pain. These devices, drawings of which are in his collected papers, were effective but were never manufactured for use of others due to his heirs' reluctance to trade in "indelicate" items.
The "Eli Whitney Students Program, Yale University's admissions program for non-traditional students, is named after Whitney who matriculated into Yale when he was 23.
