Original Patent Drawings for Kelsey and C&P

Thought you might find these interesting:
There seem to be quite a lot of patents (with nice crisp pictures) available for our viewing pleasure on google. Here are a few of some note that I stumbled upon:

A patent for Kelsey Press filed by William Kelsey in 1880

A venerable C&P from 1891

There are quite a few more, if you care for such things.
