I first saw one of these Almond right angle drives at Rough and Tumble at Kinzers PA, and was amazed how it worked. You almost get hypnotized watching it like a camp fire!

Wow, it's like something out of science fiction (David Lynch's *Dune* comes to mind). Nothing like this is made today. We are clearly in an age of decline.

Just put the pressure back again.

I thought Corliss Safe was William Corliss - George’s brother. We have a Corliss safe which may be for sale.

Awsome explanation. We need more.

Now I understand. Mind you in use they are clacking noisy valves compared to normal slide one.

This is the best video on the whole internet in regards to explaining the Corliss valve. Incredibly well done!

"One more time, the camera got interrupted." BZZZZZZZ ... "One more time, the camera got interrupted." BZZZZZZZ

when designing storage tanks you have to install a vacuum breaker so it won't collapse if the wall is thin. Also now we use nitrogen to inert vessels to exclude air to prevent flammables from igniting (like gasoline) but in the old days they purged with steam to get the air out. Amazing a Newcomen engine could have a piston force of 90,000 psi. I calculated the force on a steam locomotive piston once at 200 psi and I think that is in the same range although a much smaller piston area.

I have been to several "steam ups" at this fascinating museum. This mechanism is most fascinating. It took a very advanced level of three - D thinking to create the motion and even more to manufacture it. I think the ball ends were machined first and then inserted into the arms of the drive then the arms were cold forged around the balls. The other fascinating things are the Corliss steam valve drive on the reciprocating stem engines an well as the huge vacuum tube triodes in the Wireless section of the museum. I hope to make the next "steam up".

cool!

3:11 For the fabrication of the pivot ball I can see the use of a Lathe tracer to cut a ball shape from half of a rod and than drilling out the material. Roughly the same thing could be done for fabricating the housing of the pivot ball. And thermally expand the housing to drop the ball into the housing.

Great rig, horrendous fist....

Just because you can do something doesn’t always mean you should! 😂

Thank you for the video!

WIAT a minute. The walschaert and Baker vale gear used on locomotives allow for a variable opening and closing of the valve. The lead and lap is changes by changing the stroke of the steam vale. Engines starting under load receive full boiler pressure, As the speed increases the stroke is shortened and less team admitted to the cylinder allowing expansion of steam to keep the engine running more efficiently. No locomotive ever used corliss valve gear as far as I know. You refer to the action of a D type valve only used on low pressure engines - stationary and in locomotives. The big engines developed in 1930 - 1946 used spool valves or poppet valves.

AMAZING

I really enjoyed this video. I build miniature steam engines, all of which have all been the slide valve type. I have my heart set on building a Corliss in the future and the beauty of the mechanism and your fabulous explanation has increased my desire to build one - thank you!!😃

At 20:20 you were wondering how much surface area there is for tubes in that wood fired vertical boiler made in 1966... If each tube is 2 inches diameter and 7ft long, that gives you 3.66 sq ft of heat transfer atea per tube. With 205 tubes in that boiler, you get about 750 sq ft, total surface area for all tubes in that boiler. Hopefully that gives decent heat exchange space, for efficiency. The automatic Columbia boiler 22:00 is undoubtedly easier/better to run unattended, and probably just as efficient, providing enough steam (15hp) to power most any steam engine on site (since they are not under much load) as long as you don't try to run too many engines at the same time. I wonder how much surface area there is for that automatic boiler?

Cool

It's fascinating to look at but an awkward mechanism . I doubt it could go at any speed faster than this without shaking itself apart , also any recipocating motion robs horse power . I wonder what the motivation was for that design .

Just found your channel and Subscribed. The sort of things interesting to me. Wish I had a bigger workshop.

Ever heard of lighting. It actually works quite well. It allows one to see what you're actually talking about so we can actually learn something instead of being frustrated and deciding to leave and never again watch one of your videos. Just a thought.

Newcomen's machine was an Atmospheric Pump. It provided Atmospheric Power, ( natural air pressure) a whole 10psi.max. So, why call it a Steam Engine? A Steam Engine is different, It provides Steam Power. That's why it's called a Steam Engine. It could provide High Pressure Steam Power, as much power as your engine could take, which explains why there were so many explosions. James Watt dumped Newcomen's Atmospheric Power and Arkwright's Water-Power for High Pressure Steam Power. Like James Watt's High Pressure Steam Engine. It was the difference between an Industrial Revolution and no Industrial Revolution!

Thank you for shoring this fascinating and educating video.... Never knew Corliss did make such....

Absolutely fascinating

For those who are not mechanicaly minded this will just be another piece of machinery. But I think it's bloody marvellous! I'm amazed at the design and simplicity of it. Who the hell thought that one up? Mr Almond must had funny thought processes, but it is of course a work of genius.

A crying shame the audio is SO bad.... Could not understand most of it...

Thank you for the video! Please post more since I will probably not be able to get there Saturday 🙂

That's one of the neatest things I've ever seen! Perhaps you can build a robot to open the other locks, like the one in this video: ruclips.net/video/_fTz2D6x20U/видео.html

very cool. Wish you would have used oil and actually lite it for a moment to see the flame looking for tails, dark or light smoke etc. to see how she really works. but this water demonstration is cool.

aint no stoppin paul!

Nice!

Id say the rod comes out and you place the right angle in the joints at a precise angle via moving the balls. Then set it back to its timed position and put the rod back through

Great to see new posts!

Rolf's work is something to behold!

Awsome!!

Tesla's non-Hertzian waves are not electromagnetic, they are Dielectric impulse displacement currents, the magnetic field component of an EM wave is very lossy and Tesla wanted to avoid this problem for power and communication transmission, an impulse current isn't affected by the inverse square law and transmission delay because it has no magnetic field, and thus no losses, provided the transmitter and receiver and perfectly tuned to each other. His hairpin circuit is one manner of producing it, run that through a tesla coil setup, preferably 3 coil, and you'll be a step closer to his system, it's apparent he was using this method for Wardenclyffe from FIG 5 of his rare notes, the tower contains a hairpin circuit in its design. The lack of magnetism is the same reason why you can freely touch the cold side of the circuit or interact with it in water without being harmed by it, no magnetism = no harm.

It's powered by atmospheric pressure, so why call it a steam engine? A steam engine's powered by steam, like James Watt's engine. It's a different engine.

It's an atmospheric engine. James Watt's engine is a steam engine. Reverse the process and you could describe a Watt engine!

Amazing. Thanks for sharing.

so besides crushing itself does it have any application in the real world!!!

Great demo

Stop with the Spherical Rod Ends, You are making My Brain Hurt!

I was wondering if anyone would know more about this. I have a small right Angle almond drive that measures about 3.5 inches by 3.5 inches. I can not find any information about one of that size anywhere. The only thing I can assume is that it is a salesman sample and was not used for actual work. It is identical to the large scale version and includes all the details that the large one has. Just curious if anyone knows anything about it.

Excellent!! Well done NEWSU. We have one on static display up at the American Precision Museum in Windsor, VT.

I'm curious about what kind of power loss this design creates compared to say gears or beveled gears? Also, it would be interesting to know what kind of power and torque this design can handle compared to gears and how much longevity is expected out of them comparatively. It's such a cumbersome looking yet interesting mechanism but it just doesn't seem like something that could take a lot of torque or speed without tripping over itself but if it's designed to run heavy machinery then I'm obviously wrong, at least about the torque aspect of it, now to find out how many RPM's they can handle. 🤔

Please dont say stolen. Good thing G Corliss didnt meet T Edison it would be the Edison valve now

Wow, what a nifty little contraption. Are you planning to fire the boiler on oil so we can see it making fire? I would love to see that. Cheers, and thanks for sharing!

Why oh why can I only give this one thumbs up 👍 👍👍👍👍👍👍👍👍
