Ok, a few more Kirby patents. I think they are very cool and just can't resist.
2823411 - Integration of Emptor with Main Casing
2648396 - The Clean Air Kirby with Onboard Attachments?
1209721 - James Kirby invents the Turbine Nozzle, In 1913! Too bad it's backwards.
This stuff is really cool. Too bad none of it ever made it to production.
