My Grandfather (Big Mike) worked on the train ferry crossing the Delaware at Philadelphia.
Thanks for the memories.
I would love to see the Boilers & engines. I was a BT in the US Navy.

This is from their website.
Norris Brothers Company was founded in 1867 by Thomas Norris Sr. as a heavy hauling and rigging contractor. Over 140 years later, the company has grown from a single team of horses to a modern company with the latest in equipment and technology. We are still owned by fourth generation family, and stand ready to meet the needs of industries in the greater Northeastern Ohio area.
Pretty cool

the mind kind of boggles at the work going into making that pattern and ramming it up with that complicated core. Surely they didn't have any form of lost foam casting back then...
What impressed me was the state of the art ladders.
Are they still in use?
Ralph
Doubt it, those ladders look pretty flimsy :rofl:
They may be still in use, this is the Wikipedia article on the plant, based on the probable age of the photo. The plant has undergone refurbishment starting in 2012.

The white blob already looks like a solid bottle.
Ralph
I dimly recall watching a 'How it's made' episode on making glass bottles; IIRC it's a two-mold process: a first mold to shape the blob to as shown here, then a second one where the blob is blown to final dimensions.

I do not know if I have ever seen a real Steam Roller, thanks. Steam Roller was always a genetic term. Is the chain on the front wheel how it was steered?
Ralph
The way they steered the engine was with the chains, it composed of a right and left screw in front of the fire box,as one side drew the chain in, the other side automatically let the chain out! The steering was handled as a normal steering wheel as you see in the picture above the rear wheel, it turned a 90 degree gear that turned the two direction screw, one side fed in or out on the top of the screw and the other fed in or out on the bottom! Both the road roller and regular wheeled traction engines were steered this way. Some manufactures even offered as an option steam powered steering with their engines, like the Avery steam engine, I'll bet they were a hand full on hilly and uneven conditions!
Yes the chain was how it was steered. it took many turns of the geared down steering wheel (with a handle like a lathe wheel) to produce significant deviation of path. When I was a kid the road outside of our house was repaired and so I got to see real steam rollers up close and I pestered the driver of the biggest until he let me have a ride and try to steer. Over the coming years I saw several more and always paid close attention to design features. I do not recall when I saw the last one. Diesel versions held no interest.
Rollers; diesel or steam, were a favorite machine to watch as kid. As ralphxyz said, 'steam' roller is generic, but seems reasonable some holdovers remained in operation 6+ decades ago. Seems, they were far larger, doing freeway work. than what is common today.
Then I fell into machine work and hadn't thought of them for a long time.
Until David Letterman started having late night fun with them. How we howled over those antics, especially bowling trophies!
Had an uncle who when he thought us kids were a little too much under his feet while he was doing something. Would often say boys if you don't get your big feet out of my way I', going to run over them with a steam roller

I loved that bit change mech.

do you know what the cam program is running the machine - It looks like the old girl has been retrofitted.
Yes - we retrofitted it around 2010. We used Linuxcnc which is controlling everything. (spindle gearbox, tool chain and changer, pallets and motion *and whatever else I have forgotten...)
A short walk around...

I'm with you, that bit changer is pretty cool! I spent several hours yesterday changing bits at my lathe to get to the proper size, it gets tiresome, also doing it on the drill press. I did notice though who ever and what ever they'r making they didn't worry about the chatter and screeching the larger bit made!

I thought it was one of the DIY retrofit setups. That is a very impressive machine.
Its amazing all the Pro features you can add to an old machine by retrofitting it, i'm currently using GRBL on an old ELLIOT 181 miller and like you im impressed with what the machine is capable of. One of these days i will load linux onto an old PC and use it to run my machine but for now my head is stuck in windows world.
Linuxcnc adds a few features i don't currently have access to like tool changing and canned cycles which would be really nice.
we also converted a 80's vintage matsuura..

The arm style changers are somewhat faster than a carousel, as two functions are essentially simultaneous. On jobs using a large tool library, time saving is considerable.
Plus the K&T tooling is mechanically barcoded... So the tool can go anywhere in the chain and you can pre-fetch the tool..
