    They say it’s patented, so I did a search starting in 1790. Sometimes one can find a lot of information in the Patent, and often this is more detailed than a hastily-written manual.

    When a person files a patent application, they can claim it is “Patent Pending”. Often, money runs out, or there is the epiphany “This was not such a good idea”, and they abandon it and it never issues. Another thing that happens is, upon review, there is a defect that prevents it from being accepted. In the above case, it appears the whole thing was based on Prior Art, and was not patentable.
    No luck, though a lot of familiar names popped up, and many, many obscure and screwball devices.

    It appears many people at one time or another had an idea about how to build a faceting machine-And some of them shouldn’t!
    Sometime, if you are bored, go to and do this search. Some will make you sadly shake your head, some will make you laugh.

    If it wouldn’t get us in deep muck, it might be nice to assemble a collection of manuals for out-of-production machines here – scanned images or create PDF files, so if someone gets/inherits one they can have that info. Some of you folks probably have manuals for MDR, Sapphire, American, Prismatic (Zane Hoffman might have these), Lee, and who knows what else…

    For some of the old extinct ones, Copyright may have expired. Perhaps current manufacturers would let you have a PDF to put up of their manuals. Why not? It would not harm them, and be a little good PR for their support.

    The picture seems to be an advertisement, not the manual. If someone has one, and it was printed before 1978, there’s a good chance the copyright has expired. If not, I suspect the current copyright holder would give permission anyway.
