The patent search at Google is easier to navigate than the equivalent at the U.S. Patent Office, although the images at the latter are a bit better. Both sites are of potential interest, as a large number of innovators in the realms of politics and economics were also inventors. From my first search, here’s 38 pages of patents, all apparently the work of Joshua King Ingalls. I’ve got patents by Warren, Weitling and Westrup that I’m looking through as well.
