One of Watt's critical improvements was to inject cooling water into the cylinder at the completion of the expansion stroke. This would condense the steam at about 120-140 F, which causes a deep vacuum. This results in a powerful suction on the piston and generates power on the return motion of the piston. The piston does not rely on flywheel momentum to return the piston. The water flow is adjusted so that it is evaporated as it condenses the steam. This is a simple addition that approximately doubles the power output for no increase in steam demand for a single-action steam engine- Genius!

When I was a kid I read a story by Mark Twain called “A Connecticut Yankee in King Arthur’s Court”, about a machinist & engineer who accidentally travels back in time, and then attempts to modernize Medieval Britain. I sometimes wonder what I could practically achieve if I traveled back in time to preindustrial Britain, or even Ancient Rome, with just the clothes on my back and my knowledge and wits. Could I build a steam locomotive, for example? I understand the basic theory. But there’s all kinds of little details like this linkage and the problem of non-linear crankshaft motion that get glossed over when you read about the history of steam engines, or don’t come into play on toy models. This is good stuff. I’d be curious which steam engine design Mr. Pete would make if he were the time traveler, and wanted to make a prototype locomotive.

You always deserve a thumbs up Lyle, I'd give you two if they'd let me.

It IS difficult to explain that link motion. You nailed it if we paid attention.

Good to show the tackle box to illustrate how far into everyday life this invention has penetrated. Your model is exquisite. You will I am sure know that in Watt type real life pumping engines that beam casting could weigh upwards of 50 tons. Mounting them in a stone building atop a Cornish sea cliff was surely a art in itself. Yes, great video Mr.Pete 👍🏼

[@rexmyers991]

Oh, you deserve a thumbs up Sir!

[@peteengard9966]

You did a fantastic job explaining the linkage. Thank you.

[@edl5074]

Fascinating!! Mr pete your dad came out today from your memories . Thanks for the hard work it takes to make the video great work !!

[@scottjones7279]

The special parallel pliers that you have is a good example

[@johnmortland1558]

I like the slow motion views of that classic engine

[@AdrianPardini]

Thanks Mr. Pete, it's always a blessing to start the day with one of your videos.

[@rustymachineshop9456]

Thanks Mr Pete

Good Morning MR PETE I truly love the engineering that goes into the BEAM engines. Every time I watch one of your videos I learn something new. 👍👍 When I was in electronics class in I guess 1985 I remember hearing a story about him and back then I was more interested in other things. I actually made a folding staircase that used WATTS engineering and I didn’t even realize.I love the detail you go into on every video. Thanks for another treasure……

Happy Birthday Henry, thanks Mr Pete

A piston with a wrist pin has to have a skirt to keep it aligned with the bore. The cylinder has to be a little longer to accommodate the skirt at the end of the stroke. What could the advantage be with the very complicated parallel linkage? It's beautiful and mesmerizing but must have been costly. The benefit of a double acting cylinder makes the cross head system understandable. Just wondering.

I worked on and operated worlds largest stationary steam engine 33,000 hp (mesta steam engine) republic steel Cleveland Ohio engine was used to drive 44" rolling mill.I was also engine repairman until layoffs in 1983. 2 hi pressPistons weighed 7 tons,low press 11tons. My dad started in engine room from 1952 until 1982. We had steam duplex pumps for 600 psi H2O press for mill equipment operation, steam driven air compressor,Jack G.

[@frankpresley494]

Enjoyed the video a lot. The close ups really helped understand the assembly.

[@daveharriman2756]

An absolutely fascinating topic, thanks, that beam engine looks so graceful when running, just beautiful

You will notice that the movement of the connecting rod in the pictures of Watt’s earliest models is transmitted to the flywheel via cog wheels. At the time of his early developments, the simple crank had been patented and Watt used his ingenuity to circumvent the problem of connecting lateral motion to circular motion of the flywheel.

I'm near 70 yr old now but as a kid growing up in the rural south . Once chores were done I would grab a volume of Encyclopaedia Britannica book's of knowledge that where printed over 20 yrs ago at that point and would read them from cover to cover . I learned to read at 5 yrs old of course much of it I didn't understand at the time . I was destined to be a mechanic, as stuff like this just fascinated me . Was always getting myself in trouble trying to build or recreate things , like once when I was around 9 yrs old I ruined Moms tea kettle trying to adapt it to a steam engine I was building. Man that was whipping I've never forgotten 🙄🤣🤣. Or when I was like 7 an decided to disassemble a Scott's Outboard engine Dad had in the shed , yep another trip to the Woodshed for me 😮.
