Nice littlescoop for loading the trams. How was it powered?
I didn't see it in a quick scan of the description. Patents sure where sorter back then, mine is a LOT longer after the lawyer spiced it up.

A man-sized machine and a man-sized job are effectively handled by 21-year-old Virginia Grochowski of Milwaukee, Wisconsin. Employed by a Midwest supercharger plant, this former hosiery mill worker operates these giant drill presses as expertly as any man. Allis Chalmers Manufacture Company. October 1942.

Knew that machine tool instantly. NATCO Multi-Spindle Drill Press, common to run 21 spindles. Close spacing would use RH and LH bits for a compact gear train. The head descends to pre-set stops, varied depths accomplished via individual toolholders. Despite ungainly size, an efficient production machine from Indiana.
And believe it or not still sought after.
I appreciate you input about that machine. Makes some things click in my brain.
I appreciate that. I don't get too much toolwork in these days, so compensation is in form of historical and topical comments.
And worst fabricated quips ever.
I noticed between Ms. Grochowski's brace of NATCO's, another woman runs a single spindle on what might be a box jig. Her machine might be an Edlund, Avey, Ettco; doesn't matter. They and others built a tremendous variety based on box column versus round. You've never drilled until you lay hands on such a machine. My favorite are Cleereman, and Fosdick.
LOL Your comments are always great
Appreciated again . . .I work hard to insure accuracy, or at least good percentage of seasoned experience.

Two workers standing on the platform of a crawler-mounted steam shovel excavator, one of the men is operating the levers. The bucket and dipper (dipper stick) are attached to the boom, which is connected to the rotating platform. In the background are railway lines, a large shed and a train engine pulling carriages inscribed with 'Bolsover'.

A true "Steam Shovel" cool.

'Bliss Toledo Toggle Press'
That's like over 2 million pounds.
By relative size the prime mover looks like a toy.
Plus the lubrication system is really neat.
Here's a short story about the press.

"Donkey puncher at gyppo logging operations." That statement makes perfect sense to someone...
Another proof of my pet conjecture that the internet can yield the answer to any question that has an answer...
https://www.youtube.com/watch?v=zsh8hYPsHWg
yes but how does it do when there are answers in search of questions
"that the internet can yield the answer to any question that has an answer" True or not...
Today I also learned...https://en.m.wikipedia.org/wiki/Gyppo_logger
I used to live in Oregon and the term gyppo or gypo logger is any logger who is working for a small and independent (usually small family run companies) for logging operations (companies not associated with the larger lumber companies). I doubt there are many of them still operating in Oregon.

Looks very dusty in there.
That will be the oxide layer. Steam strips every last molecule of preservative from the surface of the steel. But the hot dry environment prevents corrosion forming. So you just get that thin layer of oxide that forms very quickly when the system is depressurized and moisture forms on the surface. A bit like degreasing steel with acid. If you dont apply something to the surface rust will form in minutes
Not sure what I am looking at in regard to the steam drum. Is that the inside of something like this?
