If any of the above are of interest to you, get back with me. I do have a little more information about these specific accidents.

1916 Annual Report of the State Mine Inspector of the State of Arizona, page 84

fatal accident, Miami Copper Co., 1916Nov22, H E Brown, caught in pinion wheel of hoist

A pinion wheel is a toothed wheel.

This is all the information that I have on this accident. A newspaper article may have more information.
