I happen to have a set of old thermal-paper printouts of what would appear to be a microfilm copy of this patent. I do not know who made them. I do not know the source of the microfilm. As bad as the USPTO digital versions are, I'm not entirely sure these are any better (they were entirely analog until I scanned them, but they're a bit fuzzy). Still, given the importance of this patent, it seems desirable to preserve them. So here are my 1200dpi RGB scans. Please note that you probably don't need these, and that they are very large files (192 to 200 Megabytes each). If you just want to read the patent, click on the PDF above, not these file links below. On the other hand, if you're an obsessive typefounder and you have a high-speed net connection, it would be good if these images below were copied to as many separate locations as possible so as to foster their preservation.
