I am going to have to guess, itâs-a-I-donât-know rusty valve.

a vacuum valve operated mixing valve, maybe for like a carburated diesel the size of a tank, or some industrial process. 
PS. I am guessing fast and wrong, because I donât want to spend a half hour trying to figure out what it actually is.

I,m lazy and it hurts when I think so Iâll wait till you tell us.

I think Sean is close, I think thermostat liquid cooled engine?

The cover with the broken off screw-bolts is a diaphragm chamber. Pressure signal passage visible on the âPATENTSâ cover.
It plunges downward to the vertical round section just visible behind.
Is this connected to the lever arm on the TYP A24 housing? Unknown. I think not.
That lever rotating the insert inside of the the not-iron bell piece.
A flow/load demand control valve.

With what looks like a diaphragm and possibly a cup and magnet speedometer mechanism, it might be a cruise control/speed control unit bigger than any Iâve ever seen. Either that, or itâs something else altogether 
Edit: If it looks like a cruise control, I guess it could be a governor also.

water pump??or a pressure minimizer for water?
interesting your archeologic area âŠ

And we have a Winnerrr: mr Cody 
First, and the correct answer! Congratulations!
Others had good (and funny) suggestions too, Sean suggested a mixer valve, and SteveU described his conclusion in a âanalyticalâ (?) way.
Well, this is a 1940 woodgas auto-mixer, patented by Baltzar von Platen, one of the inventors of the absorption refrigerator without mowing parts.
The lever is for coarse tuning of the mixer, for varying gas quality, it turns a brass cylinder inside the mixer, which changes the passageways for gas/air. The casted text, âgasâ=gas, âluftâ=air.
It is pretty rusted and cracked, but im going to restore it, when time is right.
I dug it out the ground under a collapsed wood-shed, after a tip it could be found there.
The other day i dug it out, Again, from my stuff, when looking for some vacuum gauges.
This is the air valve butterfly, itâs controlled by a 5" diaphragm, piped to the woodgas line.
This is the brass control cylinder, the rusted away flaps to the right is a âinverted propellerâ which was added afterwards to help mixing gas and air better, by creating a swirl.
Ooops⊠a history lesson again? Sorry guyâs

So it is found afgain, in the Balthazar museum. Congrets Cody.

Oh geez, Donât worry about the patent! Just draw it up in autocad, so we can 3d print it and cast one ourselves.

Goran you fox, you knew wich pictures to show that are not too revealing 
those last pictures are much more revealing. Wery interesting!

Iâve come to find out that resin 3D prints are fairly high temp rated. Some hot enough to cast lead into. Only issue is the extra HT versions are also brittle. Maybe a mixture of the âtoughâ aka flexible resins and the HT resins would work out.
If I was good(or even basically knowledgeable) at CAD Iâd love to try out a 3d printed throttle body. Resin also is fluid tight which not all Filament prints can do easily.

They make a lost wax filament now but it is kind of expensive, or you can use PLA in a âlost wax castingâ. I havenât seen anyone try it with iron though.
FreeCAD is free. It take a few minutes or much longer to get your head wrapped around it. There various instructional videos on youtube and udemy has classes. You have to spend some time with it. But it is fairly full featured, and donât expect to learn all the workbenches.
But even after you know it, you still have to sit and measure all the parts and pieces if you are going to copy something. But then it is at least documented.

Honestly, it would be worth your time to spend to learn FreeCAD. It is full featured, completely free, and it has a lot of high end features that are like âaddonsâ even in like autocad. It is good for both additive and subtractive, and you donât have to own the equipment, there are people with services that you can outsource production to. And you are of the generation that will find a uses for it for a long long time.

Well, I woke up after the nightshift and saw this
The pipes for the greenhouse arches are 2 3/4â od and all the bracing pipes are 1 1/2â, there must have been quite some weight on there.
Well, I guess I know what I have to do in spring, have a few ideas on how to solve it. I have four more complete arches lying in the barn unused and am thinking of using the barn wall as one side and have a half-circle down from there instead because I donât think this is all salvageable to put up as it is now, and whoâs to say this wonât happen again in a year or two.
Well, it is as it is and I am happy noone was in there.

Oh, nooo! 
I hope this doesnât interfere with your gasifier construction schedule.

No way, this wonât get work on it until the snow is gone. So there is time for gasification still

Thatâs a hard pill to swallow Johan. We have quite a few grow house set-ups in my area and this is a snow belt as well. A lot of them use a center beam the full length of the structure and posts about every third frame. Then a pipe to a purlin mid-way in the half arch like a peace sign. I built some geodesic domes in my hippie days and I am still a fan. If I were to build a tunnel I would do it like these designs from Paul Robinsonâs site. Iâm a fan of his as well.

Some videos about a similar situation. This guy had a whole aquaponic trout set-up in his. A couple of videos about him tearing is system down. pretty interesting. Snow is no joke. Building codes in our area require a 70 PSF snow load. I keep my house roof shoveled anytime is gets over 18 inches on it.
