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?

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
