@Cloxxki,

I do not wish to say too much here as this is a thread for real world applications. But, if an inventor patents, then what he described in the patent must be as stated. If not then anyone discovering his deception can submit a new patent with the correct information and override his patent.

Now if he leaves anything out, like the design of the weight supporting structure to keep it a secret, then he is taking a chance that it will not be discovered before he comes out with a working machine an a updated patent. Even if someone else does he still has the rights to the original design, but not to the weight supporting structure.

In Sjack patent he stated that the hockey stick approach was in development. The drawings showed the original stand guide design that was used with the radial guides. It is very apparent that the stand guides would be different for the hockey sticks as oppose to the radial guides. Just study the video carefully and you will see it is different.

Regards, Larry

Thanks Larry,
I saw several slot types in that video, on of them being wide enough to grant the weight freedom of movement as it rolls of the lower ramp. He likely perfected upon anything he showed there, or he had been presenting a working machine, though still.

I was thinking along the same lines. Our "alternatives" are now public. Perhaps if he is planning to sell out to the utility companies to shelf the design, as a citizen we could object te design for not working as advertised, or even not-new. All he needs to do is show a machine that does, without substantial additions or amendments to drawings. Also, his design seems to be most similar to prior art, possibly making it little more than a continuation upon open source technology. No patent to be granted, just (other)plans to be sold and shelved. Just for us to find out how he dunnit, hopefully one of the solutions posed here, not conforming to the application document.
Someone may need to step forward and object to the claims in the patent. Unfortunately, that can get expensive unless you're able to represent yourself.

The picture is of a full size template for the stand guide and the radial guide. The offset roller assembly is shown at the intersection of the two surfaces. This is how it looked from a hand held test run which had no parallel problems. It sill has a pinch effect.

The other gray roller is to show the expected position of an in line roller near parallel surfaces for the same intersection.

The second picture is of the offset roller. Since it is not a full assembly, the extended metal bars were used to keep it on the two surfaces while testing.

This only solves the parallel lockup problem, it does not seem to make it a runner, so I won't be building yet. But, I will be trying some other designs for the weight assembly based on observations from the movie.

Regards, Larry

Hi, @All.

First, I'd like to say that, @Dusty, you're the man! Your work is fantastic.

I've just recently caught up on all the posts in the general thread and have posted some ideas that I'd also like to put forward here for real world modeling. They include some stuff that @Dusty's already touched on and have some similarities to @LarryC's new stuff (I like it) as well. Here are my first two posts -
http://www.overunity.com/index.php?topic=7150.msg183418#msg183418
and
http://www.overunity.com/index.php?topic=7150.msg183590#msg183590

There's more coming as well. I've come up with a slot design that's kind of a cross between the hockey stick and the semi-circular design. It looks more like a Field Hockey stick at the moment but I'm going to refine it to what is essentially a quarter of a sine waveform. I also think that Abelings "D" and egg paths are generalized in the patent, and that the straight part of the "D" is actually a kind of "S" curve also with trigonometric curves. I'm working on an rough image in Painter X (which is kind of like Photoshop) where I can rotate and reposition layers so I can plot the guide path.

Please, check out what I've posted so far and give feedback.

Thanks - Dar

Please view this post of mine in the general thread - http://www.overunity.com/index.php?topic=7150.msg183618#msg183618

I'm posting to this thread as well because I'd like to see this modeled but I don't think this could be done easily in low end 3d, let alone 2d, sims. Unfortunately, I don't have access to a shop. I'd be willing to help pay for parts if someone is interested in building it.

I don't have a shop (also, I'm in The Netherlands), but would be willing to spend some night and weekends helping someone out where I can (as a personal DJ even if that helps). I do have relationships with a local top notch CNC facility. If a good design (preferably avoiding Abeling's claims) is proposed or modeled, I could have a buddy Solidworks it to great precision, and then perhaps have it prototyped (yet working) at small scale.

Greetings Larry, Closski, and welcome to the forum Beastmaster.

 I like the twist I am seeing in this. I have also played with some similar twist with tracking but not for that basic design. But in this basic design it still has some negatives that tend to fight back hard. So good luck.

The first pic below is of the foot shaped bottom of the hockey stick. A likeness to a heel, instep, and toe can be seen. Various shapes of this design can be seen on the wheel. At first I thought that some addition piece would be inserted, but after my previous testing I can see another concept. Also, the gap between the stand guide and the carrier seemed larger then needed for just a separating washer, so possibly a weight.

The second pic is of a possible design that takes advantage of the foot shape to send the impact into the toe. Please excuse the rough drawing, but I wanted to pass this concept on before I went out this morning.

The purple is the stand guide, blue is the radial guide, orange is the radial roller, red is the stand roller and black is the weight.

The accelerated weight assembly would come off the stand guide and be forced to pendulum (low loss of energy) around  the heel by the radial roller, by the time it passes over the instep hump, the weight would be pointed towards the center of the toe. The impact into the toe would produce the rotational energy.

I will be doing some testing with just that section of the machine to confirm this effect. Also, I believe the weight now shown on the stand roller rod, may need more adjustments.
 
Regards, Larry

Addition: I think the purple stand guide should be higher up, bringing it closer to the heel.

Well apart from reading some threads, I have tried out some suggestions: A rubber band between the weights...not a succes.

Taking out the "hump" from the top part ellips, showed promising results.
Changing the slots to two halve circles/moons, also made a difference.

The change of the hump and slots resulted in the "scissor" action and gives an increase in speed at the 11 to 13 o clock, creating an impulse in the right direction, clockwise. The lowering of the "hump" ,the high bump at 12o clock, resulted in a lot less ccw reaction and more clockwise. At higher speeds the scissor effect works great, at lower speeds..a lockup occurs sometimes.

All just with manual pushing around...

I can try to get some pictures showing the effect of the changes I made.

As for teflon and watchmaking skills. The friction is not the biggest problem, it is the geometry I found out.

And yes I am looking for a way to find out what Abeling did with his weights and guides.
 I have been looking at Jan Rutkowski's gravity wheel. I like the idea of "keeping" some weights in "the waiting room", ready to be launched when it is "their turn"

I hope we get to the stuff, I am afraid Abeling never found, to get something running!

Thanks for the information, all observations help even if they work or not.

Have you tried the offset roller design yet?

Thanks for the update Eisenficker. Glad to hear the hump and slots changes made for differences.

Before you go as complicated as Dar's idea (which I'd love to see in action by the way), perhaps changing the slots to wider ones, with a short hook, and the axle side of the slots advancing radially could bring some further differences in result to offer greater insight in how these weight want to/are able to move.

Perhaps that in the "waiting room", the weights could do even more if so considered convenient: a more spiral initiated sling, for instance. Put some extra work into the wheel before taking it right back in the sling.
I accidentially stumbled across a folding linkage rod design (right in half 6-12:00) resulting in a perfect D shape. Too perfect, wit would require enhancements. The lower ramp is part of the folding rod, and also the waiting room and the sling are also present, but in a different timing. Lots is possible, and can be created simply even.

The wheel without the "hump"...

http://www.youtube.com/watch?v=GT9C9xptMdY&feature=channel
Very nice work Eisenficker2000!

If you could change one set of slot to allow radial advancement of the weight when riding the bottom ramp, I bet you'd get it even closer. I cannot give you elaborate torque or vector calculations to verify this assumption, though. It just makes sence to me to make as much height as possible, as early on as possible, and not give that up to the wheel too easily.

With the wheel being so small (I erroneously types slow on Youtube), it's easy to think you've got too little weight moving there. I'm sure you've tried both adding to the moving weight and the wheel already?

Keep it up, you'll get there some day. A table sized model would be most vital to spread the word. Your setup looks like it would be easy+affordable to replicate, or produce in series for distribution. Let's hope we'll need these properties soon.

The kinetic effects in the wheel, with up to 6 "Weights" in the waiting room left. A bit similar to Abeling his explanation on the white board.

It demonstrates the wheel is a bit too small to get some "falling" speeds that count. The geometry off the ellipse is not correct, it is too thick/wide.

After some experimenting with seesaws and weights I say bye to Abelings slotted wheel for the moment.

Hoping Dusty will get positive results!
