Is that a heating element? Like something that vaporized a container of liquid? That could be an old bug fumigator.

... or even a small space heater.

got to be done type of thermostat. probably mercury filled
is it really heavy for its size?

>>2975353
Yes, fairly heavy I'd say.

definitely some sort of displacement switch. movement of the internal bellows changes the volume which effects the level in the upper chamber with the coil. maybe related to a boiler water level control system from long ago. just a wag

Not OP but a similar question. This is some kind of ground clamp I found in a barn. What kind, like what did it go to, and what is the body made out of? Is it Brass or Bronze? If so, how can I tell them apart? If not, what else could it be? It is not steel, iron, copper, or aluminum. Non-magnetic, no rust, hard, and heavy.

Looks like a pipe cutter, but I can't see if it has a cutting wheel from this angle.

It is not a pipe cutter. It the picture of >>2975541 the little stub pointing towered the bottom of the image is copper wire that has been cut.

With the jaw closed it is about 6 inches by 4½ inches.

looks like a fogger heating element.

Maybe a ground for an arc welder

Huh. Yeah, that seems like the most obvious use case. Most of the ones I have seen are the spring clamp variety. Even really old ones. But it does line up. I'm guessing it is made of some type of bronze then. Man this would be a pain in the ass to screw and unscrew every time you changed pieces. Maybe it was expected to clamp it to a table and leave it?

the spring ones are trash if you do any amount of serious work. they get hot as fuck and pop off at inconvenient times. plus new inverter welders start the arc with a voltage pop that arvs on weak clamps and breaks the circuit leading to a shiity weld start

>>2975372
Is that threaded part for a fuse or a lightbulb?
What does the bottom of the bottom part look like

>>2975596
>>2975595
Looks to be some kind of old staker or crimper for electrical ends.

That's just an LC tank circuit with no rectifier - a cool circuit but pointless on its own like that

Yes but with the coil, he may be on to something. It could be some sort of matching coil for Shortwave/Amateur Radio/Police/Fire/AM/FM

People still make these diy/commercial

Also it could be a little heater thing but it cant get too hot because it would melt the solder connections. But also looks like a mica sheet insulator. Maybe low heat to keep condensation out of attic?

>>2975341
>there is liquid in there.
Probably just loads of benzene.

That's an adrenochrome collection device
Pop it open and drink the magic potion inside

>>2975341
Does it emit heat?

This.
Probably for a transmitter. Cap is minrral oil filled for HV.
