Have you tried the Google patent search? 

http://www.google.com/patents?hl=en

If you're just looking for secondary information, you can search through
Google books. You might be able to download books from the time period.

It takes a lot of searching, but you might find some great stuff. Good
luck!

Subject: 19th century patent medicines

Greetings all,

Sorry to interrupt the recent deluge of button emails,
but I wanted to ask if anyone might know of references
that discuss ingredients of 19th century patent
medicines. Specifically, I am interested in
ingredients that went in to worming medications, and
those medicines which claimed to cure dysentery. 

Thanks,
Jeremy Pye
