Hmm. Looks like it could be made to work. But the orange gear hooks look too deep, I think that as the gear rotates the hook would fail to let go on the other side. Then the entire thing would jam up.

Jimmy, thanx for appreciation!

You're absolutely correct in your study.

The wheel with the hooks is the great point in my hard modeling and I have done 5 protos, without good results...

All that heavy pile falls down with huge power and some danger to fingers... 8)

Up to know the wheel fails DUE TO A MECHANIC detail BUT not due to BASIC questions of conceptions!

Other point, a new model will apply a 22 better hooks in order to get better momentum,

the legnth of the chain depends of the distance beiween the rails. The moment, the orange gear pushes the chain into the narrower rails, it needs all the power to lift the chain to it length. the little diagonal bit of rail, where that force is induced, is just missing!

Stefan,

not sure, but I guess you are talking about some detail that maybe scape to me.

The chain - in contracted or expanded state inside rail columns - is totally armed by itself contact and gravity.

Both columns ( +/- ) work absolutely as FREE directional pistons under 'g' laws.

Both momentum antagonism happens absolutely applied over the wheel diameter.

Murilo,

thanks for appreceation!

after rereading your concept i finally got the point with the moving hooks as part of the chane.

now i see, there are two regions of acceleration; 1. when the chane is forced to bend by means of theorange wheel (so the hooks can come into 'long'-position), and 2. when it is forced to straiten while leaving the orange wheel. that moment the 'inner' wheel of the chane needs to seperate from it's following one.

which it cannot in your design, because it's hooked to the orange wheel...

assumpting the 'outer' wheels of the chane arefree moving, they can be driven by bended rail which carrys the full weight of the chanes (like a virtuel fulcrum).

the orange wheel may not have any teeth to allow a smooth liftoff of the chane, but there can be a smaller excentric teethwheel to transmit the power. i don't see why it should not work...

heartly whishes,

stefan

Stefan,

thanks for your opinion and I'm glad you understood to my conception.

Most of people that reach the core of this design will say as you said at last phrase:

''I don't see why it should not work.''

It's very simple but of hard construction and that's why I chose for a computer simulation.

The above photo shows my model at the point it got stuck in my poor skills.

Thanks again and best wishes.

Murilo

PS: I couldn't attache said photo.

Murilo,

this time I dont have to tap my smartphone...

Do the hooks of the chain easily lock/unlock just by gravity, if the chain is bend in the propper way?

It should be possible than, to place the chain in a double-U-shaped channel just sawn out of a wooden board by a jig-saw. Friction would certainly be quite high, but could be eleminated by using ball-bearing at the chainlink-wheels etc.It would omit any hooks or teeth, which hinder the in and outfolding of the chainlinks. it might not be running smoothly but good enough to see if it is working at all (and for me it seems much easyer than computersimulation)

I guess, the funktion is somehow similar to sitting on a swing gaining momentum by lifting and lowering the barycenter - an issue I spent a lot of concideration upon...

Stefan,

nice to know that you are still on this.

You're correct about similarity to a swing and the 'wheel's diameter' is a key to the set.

That wheel and reversion is very critical since the counter pressure is a thing to win and 'transferred'.

The idea is to allow the minimum of losses, that by the way, are not directly LINEAR to the main potential.

There are hooks with kind of spring and not so hard to be done by skilled people.

In a simulation those hooks are going to follow 'instructions... 8)

The sketch you sent will for sure cause big friction and force the elements to counter turn, due to mechanical touch.

Thanks a lot! Murilo

Murilo,

I wasn't notified by RG, so I've got Your answer today.

As far as I understand the set, the main-thing is the "acceleration" of the chain taking place while bending (black circle A) and unbending (black circle B on my scetch), when the hooks are taking affekt.

If the chain is carryed by the red band-convayer and guided by the green one, traveling at equal speed, and the slower orange wheel, there are the yellow spaces, where the speed-changing may take place whithout mangeling up the elements.

It seems all that simple!

Stefan

Update...

Stefan,

I'm glad that your mind is working on this subject!

You see, this principle may be modified and upgraded by many different ways, according different minds.

Most important is the conception, that must go on.

Personally I think that the use of an well designed hooks wheel is the best solution at the moment, since the risks of friction losses are very low.

Pls, try to see this again at besslewheel.com.

Thanks/regards!
