Many cheap and helpful inventions

Interchangeable Parts

Interchangeable parts helped people with the price of guns. Because if your gun is messed up or missing a piece you can buy the part instead of buying a whole entire new gun for an increased price. All the parts to the musket were made into interchangeable parts.

The Cotton Gin

The cotton gin helped separate cotton much quicker than by the hand of a slave. It helped people make money and produce more to ship a lot quicker. It also sparked in people making more cotton than could be shipped at the time.

The hard labor

It took a lot of time and work to make the cotton gins work at the speed needed to get the work done. Many slaves had to work the cotton gin and pick it from he fields to work it to separated fibers.
