An engine designed by one of the Corliss imitators. A true Corliss engine has a wrist plate mounted centrally on the side of the cylinder block. This plate is driven off the crankshaft by a single connecting rod; it then drives four rods to the separately adjustable intake and exhaust valves. Corliss patented those features so his competitors had to do the workaround with two connecting rods to control the valves.

yes it sure would be something to see all these things in action. about 8 years ago in Milan ITALY under one of the Leonardo daVinci museems, yes under. there is a old machine shop from long long ago. big wooden chevron cut gears for no thrust& smooth running and many wire streachers/sizers, as well as some lathes and something that took me a while to work out just what it was and how it worked. it was a D O M,( drawn over mandrl) pipe manufacturing machine. it was awesome to see.all of in in the dirt floor under the building. I wish I had more time there but they had a big function going on and closing early and I was off to switzerland the next day. I love going to Italy .

That’s a lot of CO2 in solid form there, Global Warm-alarmists.
Plant more trees!

The dumb feral animals that can talk, will cut those trees down to plant more mono culture row crops, to feed their excessive overpopulation. But those words will never be heard. Seeing (maybe my delusion) how deforestation over the past 6000 years by these feral animals, has caused a continuous changing world climate. And the history of all the wars over all those years, seems to make me think, there were too many feral talkers back then, fighting over tillable land. I don't think they asked to borrow the vessel of grain you were going to eat. Big power machinery will fix that. And now we need to rape the earth of special rocks. The game is still the same, civilizations tricking everyone into organized slavery. Make a pyramid no different then an airplane.
