Marvels in Manufacturing

This section discusses the boom of manufacturing in America and different inventions and discoveries that accompanied it..

Eli Whitney

Eli Whitney was frustrated in his efforts of monopolizing the cotton gin, so he turned to the mass production of muskets for the US Army. Because firearms were made by hand, if a part broke, another part may or may not fit. About 1798, Whitney had the notion to have machines make each part of the musket. The interchangeable parts became widely adopted by 1850. It became the basis of modern mass-production, assembly-line methods. It also helped industrialize the North, which ensured military superiority over the South. With the invention of the cotton gin, Eli Whitney made the Civil War inevitable by increasing the demand of slaves, but he also helped factories flourish in the North by inventing interchangeable parts.

This is the patent for Eli Whitney’s cotton gin. It was patented on March 14, 1794. The cotton gin made possible the cultivation of short-staple cotton by removing fibers and seeds. Cotton cultivation spread across the South and the need for labor grew.

“The patent system secured to the inventor for a limited time exclusive use of his invention, and thereby added fuel of interest to the fire of genius in the discovery and production of new and useful things.”

-Abraham Lincoln, 1859
