I'm not the best at computers so I'm just posting this link to a wonderful photo of a lineshaft shop. This will take you to other photos as well.
I was looking for a link I lost with a failed hard drive to a page that gave nearly a hundred photos entitled something to the effect of "Love hiom or hate him, Edison had a wonderful machine shop"
I'm not a big fan of Edison, as he was mostly a genius at exploiting other peoples' ideas. He was, in any case, highly successful and historically notable.
Enjoy, it's a larger lineshaft shop than a couple I trained in. There were still some left in my "yoot".
