I wanted to learn more about these cutters and perhaps take a look at the patent info if available. Where do I begin?

^ Yes, the short answer is datamp.org, but... that patent isn't listed there. (Just sent Jeff an email.)

So... check out @Private Lugnutz's method for finding patents. I take a more circuitous route than he does, using Google to start the search.

I should probably edit that. I always try Google and/or Google Books first. In fact, if you Google "Sagendorph patent December 28, 1886," it finds the patent. My instructions are for real stumpers. Patents that Google or Google Books won't find by date alone, by date and name, or by date and name of manufacturer.
Looks like it was designed for cutting corrugated sheet metal without flattening the corrugations.
Dude was into roofing. He patented a nail-less roofing system four years earlier. See US255087, granted March 14, 1882.

^ assigned to the "New York Iron Roofing and Paint Company".

Just the name of the company alone makes me wonder what sort of gizmos were required for the installation of metal roofs.
