The central shaft has opposing threads, so when the shaft it rotated, the 2 arms (near long and far short) either move towards each other or away from each other. This would be able to exert/withstand high pressures, judging by the bracing on the arms.
Your first sentence is nearly correct but then you go a little off track. It has nothing to do with high pressures, forces perhaps but not pressures. So it is not what follows...>Finesilver24 wrote:The bolts at the bottom seem to bolt it to the wooden shaft and I think they would be attached first, before the shaft assembly is twisted. Like a well capper, or similar.
So Simon, may I hazard a guess at an old rusty well capper.seanoconn - gruagach craic!0 -

If the wooden post is fixed, rotating the shaft will move the shaft relative to the ground. If the shaft is fixed, the wooden post will be forced to rotate. The long beam (on the ground) is fixed relative to the wooden pole.
Still don't know what it is.
It is mounted on a vessel, not the ground.seanoconn - gruagach craic!0 -

Something that helps zero a cannon? Or stabilise one?"A cyclist has nothing to lose but his chain"

So, something rotates the shaft, which in turn rotates the wooden post. On a vessel. Some kind of trim or compensation device, maybe moving ballast if a vessel heels over in the wind?0

Does it move the rudder?0 -

Yay, we have a winner. It is a 'Robinson's Steerer', commonly fitted to wooden sailing ships. It's a steering mechanism.seanoconn - gruagach craic!0 -
I think Finesilver24 should have it as he/she did all the hard work. This is why I quoted Finesilver in my guess!0

It can remove liquid but that is not its primary purpose0

But is it a vacuum pump?
Also, it that hotel in Vizille?"It must be true, it's on the internet" - Winston Churchill0 -
No, it is not a vacuum pump.
Yes, that is Vizille, but that was a while ago in the "where am I thread"0 -

Not sure how to answer that
It is filled with water and chemicals. It can pump the liquid in and out, and can change the pumped direction of the liquid with a flick of a switch on the motor.0 -
