- Historic Steam Engines Series: 1808 - Mr. Watt's Rotative Steam Engine, as constructed by Messrs. Boulton and Watt, Soho, 1808, 38 Horse power
playlist: • Historic Steam Engine ...
"This is the construction which Mr. Murdock adopted for large house-built
steam-engines for manufactories, during the first ten years that he directed the
manufactory at Soho, after Mr. Watt retired from the business. The action of
the steam in this engine is precisely the same as in Mr. Watt*s original rotative engine
(see p. 459) ; the chief differences in the construction are in the nossels, and
in the working gear for opening the valves. The steam-valves are made with
tubular spindles, to admit the spindles of the exhausting-valves through them, on
the plan already described, p. 684 ; and the valves are opened and shut by the
motion derived from an excentric circle fixed upon the axis of the crank. The
foundations are entirely of stone without any timber ; and all the other parts,
except the spring beams, are of metal. The great lever is made of cast iron, and
its centre of motion is supported by a cast iron column. The rotative motion is
obtained by a simple crank, in lieu of sun and planet-wheels, and a multiplyingwheel
is fixed on the axis of the crank, to turn a pinion on the axis of the flywheel,
and thus give it an increased velocity." Farey: "treatise on the Steam Engine", London 1827

I think the most complex part to understand is that parallel motion. Apparently Watt was quite proud of that.
Great animation, but it will be great if some description is added to different parts to explain what has been done.
thanks for your interest.
please click on the first url above (archive.org/details/treatiseonsteame01fareuoft/page/n5/mode/2up)
on page 695 and following you will find a complete description of the steam engine. At the end of this book, you will find the corresponding plates.
Great animation overall. It's good to see the curiosity in people wanting to know more. I think your depiction of the crank and gear drive to the flywheel shaft is incorrect. Someone had already patented the crank so Watt had to employ a sun and planet gear setup where the gear was fixed to the end of the connecting rod and that whole thing orbited around the sun gear on the crankshaft. I'm not absolutely sure if this was employed on his original design or had to be changed in subsequent designs due to the patent infringement on the crank.
Thank you for your positive comment. Please download the very interesting book (also mentionned in my comments to the movie) "A treatise on the steam engine : historical, practical, and descriptive" by John Farey, published in London, 1827 (archive.org/details/treatiseonsteame01fareuoft/page/n781/mode/2up - this is a free download). I used plate XIX and XX as blueprints for the movie, and assumed they are correct, as the book was published shorty after the construction of the engine. See also the correponding text.
Besqt regards, Guy
@@guyjanssen1751 Thank you for passing along this excellent resource. The question now deepens as to when Watt switched to the sun and planet gear configuration!
@@randallsnow5311 My guess: as soon as he switched from pumping engines to rotary ones?
Get a better understanding on all the time and mechanical operations to put it in working order. Great animation!!! Thanks
Good explained with pics tanq sir
t.a.v Guy Janssen. Ik zou graag in contact komen met u. (Vlaamse Vereniging voor Industriële Archeologie)
Never ever seen video. Great animation 👌
where is the connection to the condenser ?
You are right - it disappeared from the Blender model involuntarily. I will have to review this part.
You are right, in this scene, the condenser has inadvertently disappeared (although visible in other scenes)- I will have to remedy.
very good
Dear Guy Janssen! I am making a hungarian educational video about the industrial revolution and I want to use your video about Watt's steam engine. It is possibe? I'm looking for free options, I don't want to pay for it, but of course I would include all the information about your video in the description.
I enjoy hearing you intent to use this movie for educational purposes. You can find more of similar movies at my playlist ruclips.net/channel/UCHbondtvPEqAaln0WmuMsYAplaylists
You can use this movie as you wish for free, as long as you show all the credits at the end of the movie. Best regards. Guy
@@guyjanssen1751 Thank you! I wish you all the best!
what did you used to create this animation
I use Blender: open source, downloadable for free, see www.blender.org/
@@guyjanssen1751 what would be the cost of creating this at those times not counting inflation
t.a.v. Guy Janssens: Vraag: Mag ik deze video gebruiken in een voordracht binnen een lessenreeks over industriële Archeologie?
Kun je antwoorden via Messenger aub?
Dit mag - geen enkel probleem. Dank voor de interesse.
@@patrickgurdebeke1128 Je mag deze video vertonen - geen enkel probleem. Zie ook mijn playlistt voor meer dergelijke videos: ruclips.net/p/PLeaFkeA7JwX4cvb3B1mDDWYkOA9Vji8Tx. Dank voor je interesse
WATTS HERE.
Loved the part with the naked guy.
Very good animation but no explanation
I am going to rework this video adding the necessary info , see "the President " movie on my playlist as example. Meanwhile you can find more info by dowloading Farey's book at (archive.org/details/treatiseonsteame01fareuoft/page/n5/mode/2up) on page 659 and following. Enjoy!

Mr Janssen - you sent me an email today, but it has been lost somehow as I am having mail problems. I wish to respond so please resend to me using the same email address
