One site you might want to browse is the US Patent and Trademark Office:

http://www.uspto.gov/

I'm not sure the site is searchable by dates, but perhaps you could do individual searches on "1960" and "1961" and so on, though the years may also correspond to part numbers in patent drawings.

Good luck.
