What's the history of these, any is it something uncommon in the
US?
I'd call it a "rotary inertia" or "worm gear inertia" press and
it
is not common in North America from what I've seen.

That's because Andrew has been hoarding them all in Texas:

Seriously though, he would be a good one to call if you want one.
He
seems to come across them pretty often...

Looks like a stamping press. In this case, knocking out 'flatware.
Put the blank in it,down comes the die, up goes the die, out comes
the
spoon / fork. FWIW, Krupp Steel started out supplying those dies.

They were wise to be ready for either war or peace.

But when he started, Herr Krupp wasn't the Industrial Powerhouse.
Rather a bit of the opposite. E.G., his first mill used water wheels
to power the drop hammer (SOP at the time). Which he put on a
stream
which didn't have enough flow year round.

New England has preserved some of that history. We took a school trip
to this place not long after it was restored and they demonstrated the
waterwheels and trip hammer and explained the tedious process of
squeezing the slag out of a bloom of iron, one of which they had on
display.

When I was little my father bought lumber to repair our 1830 house at
a water-powered sawmill.
-jsw

The house I was raised in, was built with exterior walls of two layers
of white pine planks on end. these planks were 24 to 36 inches wide, 2
1/2 inches thick and up to 20 feet long. The trees were cut on the
property and floated down the river to a water powered mill much like
the Taylor Mill with the vertical saw powered by an undershot wheel.
This mill combined the saw mill, a planing mill and a grist mill. I
never saw the mill but remember well the stone fillled cribs of the
dam and flume. We used to use the cast grinding plates from the grist
mill as a boat anchor.
The site was washed away in the early '50's when an ice jam combined
with driftwood in the forebay of the dam gave way and spread
everything downstream.
