Diese, im deutschen Museum München ausgestellte Maschine ist ein Nachbau der 'Lap' engine von Boulton & Watt im Science Museum London. Die Originalmaschine wurde 1788 gebaut und arbeitete bis 1858 in Boultons Fabrik in Soho/Birmingham für den Antrieb von 43 Poliermaschinen ( lapping engines). Sie ist die älteste, die alle Watt'schen Neuerungen enthält, und gleichzeitig die älteste Maschine im ursprünglichen Zustand . Interessant ist das Planetengetriebe (2:46), welches Watt verwendete, um damit ein Patent auf den Kurbeltrieb zu umgehen: Das Schwungrad dreht sich mit doppelter Geschwindigkeit und kann damit leichter gehalten werden. Allerdings stieg auch Watt nach Ablaufen des Patents auf den Kurbeltrieb um, vermutlich aus Vereinfachungs- und Preisgründen.
Der Nachbau wurde 1913 vom Eisenbahn¬ausbesserungswerk in München meisterhaft ausgeführt und erlaubt nun - im Gegensatz zum statischen Original -- die Bewegungsabläufe besser zu verstehen.

Im der Energy Hall des Science Museums London wurden auch ausgezeichnete Animationen erstellt. Zwei von diesen sind auch im Video zu sehen. Alle diese Animationen seit einiger Zeit auch online:

This engine, shown in Munich (deutsches Museum) is a 1913 replica of the eldest essentially unaltered rotative steam engine. Built in 1788 it was in service as 'lap engine' until 1858 in Boulton's Birmingham/Soho factory, where it was responsible for a line shafting ensemble of 43 polishing engines. The original is shown in the Science Museum London.
This engine incorporates as the first one all of James Watt's innovations:
- Double acting steam pressure combined with drawing vacuum
- Separate cooled jet condenser, without the drawbacks of Newcomen's design
- Parallel motion for guiding the pushing piston rod
- Sun and planet gear, to avoid the patented crank drive (2:46)
- Adaption of the wind mill centrifugal governor for steam engines
The amazing animations were filmed in the Science Museum London and can be watched online: www.sciencemuseum.org.uk/on-li... See the engines at work
The replica is one of the masterpieces at Munich and a perfect object for studies.
Bore: 475 mm (18.7 in)
Stroke: 1244 mm (49 in)
Steam pressure: 1.5 bar (22 lbs /sq.in)
9.5 kW (13 hp) at 46 rpm
Thanks for watching!

Thank you very much! James Watt's inventions are absolutely amazing, especially when you see the additional technological problems he had to solve at his time!
What were the problems?
Danke und das mit dem Kanal kann ich nur zurückgeben! Grüße aus Österreich!
Thank you so much for this! I'm reading Jenny Uglow's "The Lunar Men" at the moment which is all about Watt and Boulton et al., and I really wanted to see some of Watt's engines in action. This was perfect and your explanations were a welcome bonus.
Fantastisch! Eines deiner besten Videos. Ich wird das Video als Favorit speichern. Vielen Dank!
Watt was a brilliant man.
Outstanding lesson as always! Thanks!
AWESOME!
Danke, danke, ich fuehle mich sehr geehrt! Herzliche Gruesse aus Oesterreich!
2:20 parallel motion rods, for which he had every reason to be proud of that!
Magnifique!!! Merveilleux!!
Tolle Maschine und interessante Videos im Kanal!
Merci bien Raphael, enchanté! Des bonjours de l' Autriche, Harald
Watt's biggest and most important innovation was to dispense with Newcomen's Atmospheric Power, for Steam Power.
To achieve this, he had to invent a new engine, the world's first practical Steam Engine, in Scotland.
I like the way you label parts on screen its very helpful Thanks
klepper00 I also
Oh you're welcome! Thanks for watching and friendly comment!
Bonjour,
Very interesting engine, and thank you for the accurate description.
Amicalement, Raphaël
Great video. Enjoyed watching.
Thank you very much! :-) I'm pleased!
Amazing.
Huh, I thought it was bigger. But still impressive. I wonder what Mr. Watt would think of a modern computer.
3:13 that governor probable ain't doing crap at that low RPM
cool
There is a 1799 engine near Charles City Iowa USA. And the goal is to get it back in steam, flywheel is appox 10feet in diameter.
it is actually very noisy, but i still like it.
بالتوفيق فالماشين مع فكنش 😂😂👌
I wonder if they made models before constructing the full size engines..
How was the metal made for this machine... Can't have been steam power.?
Steam Powered bellows for the furnaces!
Do you know any history about this particular engine depicted in the video? (Where was it used? What was it used for?)
Your questions are answered above in the explanation section at the very top of the page!
Newcomen, Savery, and Smeaton built an engine to supply Atmospheric Power.
Watt built an engine to supply Steam Power.
In Britain from 1800 to1900.
20,000 Waterwheels decreased in number.
Windmills decreased in number.
The Englishman Thomas Newcomen's 1,500 Atmospheric Pumps disappeared.
The Scotsman James Watt's 500 Steam Engines and their descendants increased in number to 10,000,000 !!!
For every SINGLE Waterwheel in 1800 there were now 500 James Watt type Steam Engines and their descendants in 1900 !!!
The Power output of the whole country increased by 500 times, and so, Production capacity !!!
In one human lifetime.
And you don't need a flowing river of water for each one either!
This WAS the Industrial Revolution, it was a Power Revolution and it was kicked off by only one single Invention, James Watt's Invention of the world's first PRACTICAL Steam Powered Engine in Scotland.
It was nothing to do with efficiency, it was all due to the dumping of Newcomen's Atmospheric Power and Arkwright's Water-Power for Steam Power.
Take away James Watt's Steam Power and you don't get an Industrial Revolution.
Yes, I know, and your German is not perfect but very very ok, compliments :-)
22psi? I thought pressures were lower, like 5psi.
Yes, there's a lot of deliberate misinformation out there, it's definitely 22 psi.
Ihr herzlich willkommen. Allerdings bin ich aus Amerika, ha ha... Ich hoffe, dass mein Deutsch ist okay, LOL...
You can't stare at a moment petrol diesel or electric car engines at least steam stationary locomotives ships reciprocating engines a lot more going on watch external rods moving more exciting then internal combustion engines
I came here because of math....😭😭😭😭😭😭😭
