What is that?Interesting pix, thanx mhd.
What is that machine? I guess the operator turns the wheel, which makes those pistons go up and down, which in turn rotate the arms. Is it some sort of thresher? Maybe a press of some kind? Don't we take our modern devices for granted?
It was outside the geology building on campus...
I image the wheel was turned by some sort of steam engine... New page

Or......some form of discipline for unruly geology students?
That is the remains of a "Stamp". It is used for crushing ore. Here in TC we have an operational (real ore and real gold) 8 head stamp that is part of the Battery Hill gold mining museum which is on the same site as the original (sorry, no pics). Historically they were steam driven, but the one at the local museum is now electrically driven by a belt of that large wheel
There have been many broken bones caused by these machines because of sloppy operation. Each of the stamp heads needed to be operated/unlocked manually by a bar that was inserted into the running machine. With the local machine large amounts of mercury is used to seperate the gold from the ore, so historically there have been many people who have suffered the affects of mercury poisoning. Cheers Matt
Thanx Matt - very informative.
