I used Google to search the patent number.
http://www.google.com/patents/US3199192 Prior to Google, I attempted to use the patent office data base search engine which returned a multi page image report which was not visible on my phone or laptop browser. Possibly a temporary technical difficulty.
Not the first time I have experienced difficulty researching the patent office website.
In example, I had discovered 3 similar patents related to my submission for patent approval. My patent attorney discovered 10 pertinent patents issued.
