Answer:
not all inventions but this will help you.
1. The Cotton Gin (Doubled the cotton production and took out all the seeds from cotton.)
2. Interchangeable Parts (When one part of a machine is broken, you can put another part in its place that isn't the same.)
3. Prototype Gunlocks (Created for muskets and was told by President Adams to make 15000 muskets.)
4. Milling Machine (Modified lathe that turns out irregularly shaped parts. Without the milling machine, it is difficult to see how standardized parts could ever have been invented.)
