1. Go to http://www.google.com
2. Type in cotton gin (or whatever search terms you need).
3. Read different search results until you find what you need.
4. Re-search with different search terms if you don't find all you need. In addition to the cotton gin, you might also enter industrial USA inventions and/or other search terms.
