A large library will have the US Patent Gazette, which has lots of cross-references and is organized by patent date. The gazette has all the basic info, a summary of the patent concept and at least one illustration, but won't have the entire patent text. If you live nearby, and you're used to old-fashioned library research, digging through old books and such, you'll find it very satisfactory.
Google Patents has lots of info, but the search feature is very crude and you'll end up having to sift through a lot of unrelated, seemingly random stuff (and sometimes never find it) unless you know the exact patent number. Go to the Google homepage, click the More arrow, scroll down and click Even More and then click on Patents in the menu. If you can track down what you're looking for, you can see the entire text and illustrations.
More limited, but much more organized with well-designed search capabilities - Insulator Patent Reference Library. It's mainly insulator patents, but includes lots of glass making equipment and other bottle-related patents. Link: http://reference.insulators.info/patents/ Includes full drawings but not the text.
The "official" source is the US Govt patent office, but the focus is more on recent patents (since 1976) and not the old historical info that we collectors find so fascinating. You'll need the patent number to get to the illustration. Link: http://www.uspto.gov/patents/process/search/
Yes, I'll admit I'm a research nerd, in case you can't tell... []
Thanks very much for those links and comments
