Hi Luc,


Thanks for the base vid... you are correct in not being able to see a universal joint... but really bad
engineering not to have something there! Any stiffness there is counter active, meaning the weight
is not going to fall down hill if the stress of the rod is trying to hold it vertically.


Don't forget we are dealing with a machinist of some talent here and even though the stub output shaft
is running true in two bearings, if the top is turning in a true circle
the angle will never change so the stub shaft could be either bent or machined to this constant required angle.


Incidentally, the "fatness" of the outer portion of the 'gear' would suggest chain drive to the
centre output bevel gears.


Ron

I agree with everything you say Ron but somehow I don't think he's a bad engineer, so maybe it's like you say,  bent or machined to this constant required angle. A chain sprocket would also deal with a wobble.
I'll first try like I said with the self alining bearing up top then after the chain sprocket the fixed bearing.

I made another video from a different angle which reveals the center gear also.

Ron

Come to re-think about it, I think you're right Ron

The top is turning in a true circle as far as I'm concern, so wouldn't small bends in opposite ways to each end of the shaft allow the top to swing and base to stay true?

Hi gotoluc,
In the upper part of the shaft bearings, still a bit unclear! From here it's the steel shaft has been bent or hide a cardan? . .

Yes, Luc, that is correct. Looking at the last video seems to reinforce that the shaft is bent.

For it to work the plate that holds the weight must be above the bend.

If this is true then further confirmation that the upper end of the lever/rod is performing a true circle.


Thanks,

Ron

not been here for 5 years good job my password still works

i have started building a small model to undertand what is going on..I am more of a hands on person and that is the best way for me to learn and understand this mechinism.

I have a thought experiment..Imagine a child with effiel tower balanced on its peak, upside down. any input energy to move it off center is equal to the energy to return it to equilibrium..
 
 Now while the device is chasing a continually moving center of gravity , how do we move the center of gravity without expelling the same amount of energy that is gained?
 
 I believe that the secret lies in the centrifugal forces of the second weight. As it spins round and around, its centrifugal force is used to push the main shaft or axis back and forth in its slot..it is that "Extra Energy" that moves the axis, which allows a change in the position of the center of gravity..when you study the orbit of the smaller weight it is clear that it is creating a force vector in the direction of the slot, that vector reverses every 180 degrees..
 
 the energy required by simply moving the center of gravity would cancel as per standard laws..but very little of the input energy is knocking the shaft off center , it is mostly centrifugal force doing the knocking..
 
 I wonder if there are any springs on the sliding mechanism. since the centrifugal force could both compress springs and shift centers of gravity

I have just notice that the top rood(lever) the only one that is balanced is moving in circles and not just linear left to right.
Don't know if you already notice that ,if you see video 36 to 38 sec ,you will see shadow of the bar like its twisting.

indeed ..the top plate with the smaller weight attached rotates around a central shaft,

The central shaft slides left and right...the centrifugal force developed by the smaller weight ensures that the shaft is pushed into each end of travel.

You certainly said a mouthful, and it's clear that you're on the right track.  At the rate you're going, it won't be long before you realize what Skinner was talking about when he stated that "improvements can be made".  You'll have the whole thing turned over on it's side before it's over.

Which won't be such a bad idea when the time comes....


Happy Trails,


TS

progress...ok i was only testing out my swash plate so don't go saying i got it wrong...lol need to power it up and then prony brake the output when the weght and its off center bearing thingy are added

Hi Luc,


Couldn't resist a small demo myself... no output shaft but a bearing on the tilt plate to show that
there is no input from the shaft. Now I realise that W S's model has the weights fixed to the shaft
but this is more to keep all eight sections in sync, right?

Thanks for making some tests and a demo video Ron.

As you can see it's easy to turn. Imagine when you both upper and lower stages are working, the bottom torque must be incredible.

Hopefully you'll be able to replicate how he does it without a joint.

Today I got my 8 foot high box built and I have most of the supplies ready.

Thanks for sharing

Luc

Hi gotoluc,
   Your job to build a similar machine Skinner ?

Thansk for taking the effort to reply and draw your thoughts. But i disagree..I am following the drawings by Artoj which i agree with..

http://www.energeticforum.com/renewable-energy/17195-william-f-skinner-1939-gravity-power-3.html#post257130

the input is not circular , in the original 4 shaft version each shaft is being kocked to the left then to the right  and there is no rotary input..

The knocking or unbalancing is progresivly more and more efficient as the secondary weights centrifugal force pushes the shaft back and forth along the slot as a result of the centerpital force.. That is the gain mechanism..the spinning bits are just a distraction and follow standard thoughts on inertia

agreed to disagree...

I wont bug you any more ,if you have a second look at video at 36 to 37sec,
you will see that the square that hold rood in place does not move same as the bar
