Our downstairs toilet seat broke, it caught my notice because it was unusually old and of sturdy construction. Looks like it may be almost as old as I. Removing it, I ran into springs, why springs??? looking on the internet the manufacturer, Sperzel in Minneapolis, was one of five toilet seat makers, but is now out of business.
I did find patent information. As detailed as the patent is, it doesn't say why there are springs, rusted necessitating a Sawzal cutting of the thick bolt while not cracking the bowl.
This led to researching Recip blades, Lenox being the best, my craftsman blades were crap. While searching for blades, I was reminded to use the 4.5" angle grinder, which I did, taking a about a minute on the 2nd bolt, much quicker than my hour of hack/recip sawing on the first.
Additionally curious is that the seat designed to have a limited swing is mounted on a standard tank toilet whose tank abrogates the need of a swing limit. My latest theory is this industrial seat was taken from the hospital by one of the previous Doctor owners.
Sperzel is also the name of a Cleveland company that makes guitar machine heads.
