Compressed Air Mine Hoist?
I came across these pieces of equipment in the desert of central Arizona. I am trying to understand how the mine hoist operated. Wonder if it was an air hoist that could have been powered by the air compressor? Any thoughts appreciated.

Re: Compressed Air Mine Hoist?
One looks like a Fairbanks Morse N engine with a cable winch on the back of it, and the other one looks like a belt driven air compressor.

Re: Compressed Air Mine Hoist?
Thank you for the response. Your info gives me a place to start on the hoist engine. 1906 newspaper accounts of the mine note that a 25 hp gas engine and an air compressor were at the site.

Re: Compressed Air Mine Hoist?
The item with the winch, is definitely a gas engine - the pot muffler is still attached! Have a close look around - the missing parts may be on the ground nearby. Sometimes a metal detector comes in handy! do you know what was mined there?

Things haven't changed much since I stumbled upon this picture in June of 2015. Hot tube chimney is moved a bit.

Re: Compressed Air Mine Hoist?
Investors were mined. 1.7 million shares of worthless stock were sold in this mine from 1906 to 1908. In 2017 dollars that amounted to 4.7 million dollars. 4 of the promoters were sentenced to a year in Leavenworth. Two took off for Canada. One was pardoned. It is unknown what happened to the fourth......The mine was promoted as a gold time with ore averaging $200,000 per ton.....

Poking around elsewhere on Smokestak, I believe that the hoist pictured on the semi trailer is almost exactly the one in my photo.

Re: Compressed Air Mine Hoist?
From a 1908 catalog here is some information that might be of interest. Looks like that by counting some teeth on the gears you could determine the HP of the engine.
