PRESENTATION OUTLINE
COTTON GIN
BY KATIE CARR
INVENTED BY ELI WHITNEY
- first modern mechanical cotton gin was created by American inventor Eli Whitney in 1793
HOW IT WORKS
- 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
- 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.
TODAY
- Modern automated cotton gins use multiple powered cleaning cylinders and saws, and offer far higher productivity than doing it by hand.
INTERESTING FACTS :3
- Whitney wrote that "if a machine could be invented which would clean the Cotton with expedition, it would be a great thing both to the Country and to the inventor." In the same letter he boasted that his invention would "do more than fifty men with the old machines."
- Whitney and his partner, Phineas Miller, kept the cotton gin under their immediate control by selling ginning services, not machines.
- When a fire in their New Haven manufacturing shop delayed a shipment of gins, southern blacksmiths began making their own versions of the easily copied machine
