New Low Water Cutoff

In the late 1800's John Ashcroft started selling his new device, a low water detector. I like that he said more than 8,000 are installed.

seems awfully elaborate to do what a float could do…

Was that a one time use device?

You'd at least have to replace fusible metal D

Why does it seem elaborate, @mattmia2 ?

Better than nothing

"remind me, is that the quitting time whistle or the take cover its gonna blow whistle?"

"hey is that just regular silence, or the silence of the hartford loop not doing anything while the boiler steams out all of its water?"

you can find some wild stuff scrolling through patent files also

I did a search for solar thermal once, crazy inventions that received patents
