What was Eli Whitney's cotton gin made of?

Eli Whitney's cotton gin was primarily made of a wooden frame that housed a series of metal hooks and saws. The machine used these components to separate cotton fibers from the seeds, significantly speeding up the processing of cotton. The design included a rotating cylinder with wire hooks that pulled the cotton through a mesh screen, allowing the seeds to fall away while retaining the fiber. This innovation revolutionized the cotton industry in the early 19th century.
