The " Gary effect " and the Wesley Gary motor.
« on: July 03, 2018, 02:53:20 PM »
I've long been fascinated by a simple mechanical magnetic OU device that was presented by Wesley W Gary in 1879. A fully detailed account can be found here from the many pages of the Rex Research website.

http://www.rexresearch.com/gary/gary1.htm

The device appears to be a simple put together and run project but has proved to be almost impossible! Well, for me anyway.

WG's motor works on a discovery he made that the magnetic polarity actually changes within a soft Iron armature when placed at a certain distance from the permanent magnet. Here's a video of my confirmation of the so called " Gary effect " in action.

https://youtu.be/ACykTfXspfM

I then followed up with this where the action nearly came together.

https://youtu.be/XA8RmmvrvH8

Around that time the TinMan was also experimenting with a rotary version, the first device of his actually flew apart but upon rebuilding the effect never reappeared. The following video is of my own version, there are several others too.

https://youtu.be/LMGcFtH18hE

Life goes on and my poor replication attempt was shelved, along with all the other failed OU devices....

I recently decided to have another look and remade the seesaw/teeter totter with sections of transformer Steel and Neodymium magnets.

https://youtu.be/Y-NzUOkGzGQ

I opened this thread in the hope that there's a few
 " mechanically " oriented folks out there that are possibly unaware of the Wesley Gary motor and his " effect " that might like to jump in and try a build.

Since that video I have replaced the " polished " pivots with precision ball races and fitted the device with my homemade high Carbon Steel bar magnets. The results can be seen here.

https://youtu.be/CFT5PZgpz5c

To conclude this first post, of which I hope there'll be many more from other contributors??  I'd like to make a few suggestions/observations that may help see us to a device that could,  " change the world " !!

Size.

Ah yes, I think it does matter here. The whole device seems kinda weird as it works, more like reaction following action or vice versa. If you build you'll get what I'm saying. It's non linear, very different to an IC engine where you can have properly timed actions. Too small and the lack of Mass will inhibit change, unless you're a retired watchmaker of course.

Magnet choice.

Back in 1879 Mr Gary would have had but a single choice in material. Many shapes and sizes but still one material, high Carbon Steel. I'm of the opinion that if too powerful a field is used the effect would be literally overwhelmed or the distance too great. I'm also pretty sure that we need to use long poles to ensure a proper North and South is seen by the armature.

This device although simple to look at is very complex in its action. Care and attention to detail will be paramount. Every piece will need to be well balanced and polished where necessary. Friction is our enemy and must be eliminated, everywhere.

It seems strange to me that a device that was presented well over a hundred years ago, allegedly working, that there's hardly a single reference today. Was it a hoax? Fact or fiction? Can we prove otherwise?

Over to you....

hello,
I also pursued Gary's motor for a while. I reached the same conclusion as you as to magnets. I bent 4130 .250 rod into horseshoes and magnetized with big Neos. It is a game of patience and little improvements which I failed at. I wish you luck. The man with the two stage mechanical oscillator claimed that spring steel supports were one hundred times more friction free than ball bearings, so that might be an area to look at.
Good luck, Garry

Hello Garry.

Welcome, it's good to read of another that's possibly got to the " hair pulling " state after many hours of tinkerings. :)

You'll know exactly what I wrote about with the non linear behaviour?

I'm now trying the armature as shown in Figure 2 from the Rex Research literature, linked in my opening post.

What did you use for your armature? I chose transformer Steel because it won't permanently magnetise itself. But I'm wondering if the laminated section might upset things, lots of Gary effects? There's so many variables.

Cheers Graham.

Hi Graham,
It took me a while to find the carcass. I was into this about ten years ago. Three years ago right after I retired my shop burned. Most things in it were partly ruined or totally destroyed. All that I kept from that build was one horse shoe shaped magnet I had made. It is still magnetized to my surprise. I think that laminated material repelled each part when magnetized and I was trying to use low carbon steel, not having iron.

Hi Garry.

Well, it seems like it's just the two of us here. I'd have thought that there were a few others of a mechanical leaning that might have been interested in such a simple machine?

I now have my laminated armature fixed in a vertical plane ( fig 2 ) in the literature. I got to a point of,
OMG this is nearly there but I wasn't sure because I'd had to fix some Ceramic magnets to the static bars as they'd lost their magnetism.

I will be remagnetising them later by inserting them into a very heavy Copper wire solenoid coil and zapping it with a large car battery.

At this moment my " test bed " just has the seesaw/teeter totter facing the armature in attraction. What's interesting is that the " effect " can be seen very easily. As I raise the armature slowly the seesaw follows and then suddenly is repelled upwards.

Video?? Is anyone interested?

I'd also like to take this opportunity to thank TinselKoala for looking at the videos and making comments.

Cheers Graham.

Graham,
I became interested not because of the perpetual aspect but because he claimed a novel way to generate electricity. For the folks who haven't seen this... http://www.rexresearch.com/gary/gary1.htm

Hi Garry.

Ah yes....

Whilst tinkering with the MK 2 a couple of years back my son and I suddenly had the thing vibrating uncontrollably, my mind was so set upon the task of a nicely swinging motion that this annoying buzzing got stopped very quickly. It was only later that I realised we had managed to create the Gary effect but at high speed. Needless to say we never found that " sweet spot " again.

A demonstration of a working Gary motor would change everything. Perpetual motion, well the thing would wear itself out eventually. Work done by a permanent magnet would be another area that's been argued about for a long time.

As I wrote in my opening post.... It could " change the world " !

Cheers Graham.

Hi Graham,

I also played with this idea. I remember using modelling clay bit by bit adding it to create a balance to the lever but didn't have much success. I also built a linear motorized platform out of Lego with a worm gear to, somewhat accurately, adjust the metal keeper back and forth. I found an old image, that looks quite funny now, of a untested linear version idea at the time. I think the idea was to create a reverse field through the plate to cause the magnet on the slider to drop back down again.

The other untested idea was to create a solid state version where two coils were mounted at the end of the horseshoe. The bar would have a output coil wrapped around the middle. This bar would be pushed out to the edge of the neutral zone so no flux would be going through it. Now pulsing the coils at the end of the horseshoe would push the field out just enough to cross the neutral plane and cause the flux to go through the bar and generate an output pulse. In theory.

I haven't had the time to return to this, working on coding a VR project atm.

Looking through the old folder I also found some references to two patents.

Self-propelled magnetic motor or engine by Anh Tai Do

Transverse magnetomotive force system by Zhao Hongri

This second one has some interesting references/data this would be great if they can be verified.

Hi Graham,

You said you had a version that was buzzing or oscillating, do you know what the stroke length was for that? I looked around and found a patent for a magnetic actuator which requires a very small movement, .006-.007 to .003 inch actuation distance according to patent. This could be lever mounted to run a impulse, reluctance or piezo generator.

Hi DreamThinkBuild.

I was rather busy over the weekend, not much time to spare.

I've always liked your contributions to these pages of the forum, you've presented some interesting conceptions over the years. I'm happy you're here.

The unit that started vibrating was the one that came before my two latest videos on this subject. IOW the same base and supports but I had used 3/8" diameter mild Steel rod formed into horseshoes and glued small cylindrical magnets on the ends. From memory we had everything kinda close to each other and it just started vibrating. It was a one off event and as I wrote earlier it would have been considered a
" score "!!

I've been in contact with an eye witness who saw a working replication in the late 1990's. This device was quite large being nearly 2 feet long. The armature or " shield " as the witness prefers to call it appeared to be laminated but just two plates of Iron with a plastic separator. Mass saving? Possibly....

I'm still surprised that there's so few members interested, after all it's rather a simple contraption and fairly easy to make. For me the magnets were the hardest bit. I used " gauge plate " or
" flat ground stock " as it's a high Carbon Steel and after heating and quenching can be readily magnetised.

At this moment I've got a single strip of transformer Steel for the armature mounted vertically between the magnet pairs.... It's the best " Gary effect " action I've seen to date.... Short video to follow, soon I hope.

If you're going to build, think big the more " ponderous " the better because the action/reaction phasing isn't really phased at all, very difficult to explain until you see it for yourself.

Cheers Graham.

Hello everyone.

Here's the video I promised earlier, constructive comments welcomed.

https://youtu.be/nq8-c0IRlps

Oops, I forgot to mention in the video that the magnets are in " attraction " mode.   :)

Cheers Graham.

Here posted with Grum's permission is a recent comment from Cyril [Smudge ]

Smudge quote to Grum
Quote
Grum,

A significantly large part of the magnetization in Fe (and presumably also your steel) comes from the conduction electrons which are mobile.  So as the Gary effect motor oscillates, these electrons move shifting the magnetization about.  Think of them as tiny bar magnets that can move inside the steel.  It is possible that the finite delay time associated with that movement is what allows the thing to sustain oscillations.

end Quote

and Smudge did add this part

Quote

So when you have something "working"  (i.e. showing damped oscillation) you could try making the fixed bars into delay lines by winding a series of coils along their lengths then having capacitors at each coil junction connected to  a common "earth".  See if it performs differently.
