I found this reference but it may be the one you started with.

Hi Bob,
It is a patent on casein. I have the inventor/applicant, a John Robert
Johnson, and a possible date (1870) and a possible number (201) but I
cannot
locate anything with those parameters. I think the date or the number
is
wrong but I can't just scroll thru all the patents, it seems, of the
year
1870. Oh, I think it is a British patent. I've tried the uspto.gov and
the
http://gb.espacenet.com/ but still cannot seem to get to what I want.
I've
tried boolean operators too. I'm obviously either doing something wrong
or
one of my details is wrong.
Chris
I am currently writing a book that requires a fair amount of patent
research. I have been searching patents almost daily for the last year
or
more. What is giving you problems? I do not use the USPTO, by the way.
Perhaps I can help you?
Bob
