Zeroing in on Bessler's wheel

[JUBAT]

Would it be possible to utilize a center mechanism based on the trammel of archimedes so that as the vertical set is trying to apply downforce, it scoots the side weights over?

[Sam Peppiatt]

JUBAT,
I don't know what that is? I used a toggle link. You need two because the vertical bar raises and falls twice per revolution of the wheel. They also reverse the direction of force every 1/2 turn of the wheel. See p.83----Sam

ETA, SHADOW made an excellent drawing of the linkage that I'm using. It works perfectly.

Bonjour Jubat,
J'ai essayé votre suggestion de forcer le déplacement du poteau vertical mais cela ne fonctionne pas.
ca marche sur un demi tour et après ca bloque le retour en position.

Hello Jubat,
I tried your suggestion to force the vertical pole to move but it does not work.
It walks a half turn and after it blocks the return to position.

Bonjour Sam,
J'ai revu la page 83 et je crois savoir ce que vous voulez!
En aparté je ne suis pas meilleur inventeur que vous, je ne suis qu'un mécano qui met en œuvre des assemblages simples pour essayer de résoudre l'énigme.

Hi Sam,
I’ve reviewed page 83 and I think I know what you want!
As an aside, I am no better inventor than you, I am only a mechanic who implements simple assemblies to try to solve the puzzle.

Hi SHADOW!
I said I wouldn't refer to back pages but, didn't know what else to do. Yes, p 83 gives you the sense of it. It takes two toggles parallel to the horizontal bar. While one is pushing the other one is resetting. Then the little link that you have now,( it takes two of them), connects to the center of the toggles. Your thread p 16.

I hope you can work it out. It's ben impossible for me to explain--------------Sam

Bonjour Sam,
Si ce tracé est bon, il reste à définir toutes les liaisons entre chaque éléments.
Fixe ou pivot

Hi Sam,
If this plot is good, it remains to define all the links between each element.
Fixed or pivot

[Sam Peppiatt]

SHADOW,
NO, what I have is different. See your thread p 16 and the link or linkage at the 3:00 position. Just transfer that link to my wheel with the yellow dot near the center of the wheel. The left end is fixed to the wheel. The right end is fastened to the horizontal bar. The little link that you show, hooks to the yellow dot, or where the yellow dot was.

As you show it; it is flat across and would push the bar to the right,(outward), for CW rotation. Then when the wheel flips 180, the link kind of folds up and draws the bar back the other way. As I look at it now. maybe it only needs one. I have two, what a big dummy I am. Over thinking it I guess.

Not sure if you can fit it all in, maybe-----------------Sam

Bonjour Sam,
Si j'ai bien compris ceci est votre arrangement!?
Il faudra calculer la bonne longueur des leviers pour que cela fonctionne.

Hi Sam,
If I understand correctly this is your arrangement!?
It will be necessary to calculate the right length of the levers for it to work.

[Sam Peppiatt]

WOW!!
Yes, yes,(Wee, Wee,) SHADOW that's it! You have accomplished the impossible! Maybe a bit over simplified but, a gravity Wheel, none the less. As you can see, when the vertical one moves up and down, the horizontal one can shift from side to side, depending on which way you want the wheel to turn. If the left end of the linkage is fixed to the wheel it will turn clock wise, as shown. It's perfick!

Thanks for all the difficult work required, to put it together. God love you SHADOW for ever and ever------Sam

PS Now I / we need Fletcher to roll it over few times, or maybe perpetually as the case may be.

[Fletcher]

Hi Shadow .. can you please mark any attachment points and pivots clearly - and maybe put the rollers in the background so we can see the vertical and horizontal linkage bars on top, plus where the red and blue linkages are going and attaching to etc ..

This will help me/us understand what action Sam is after ..

cheers

[Sam Peppiatt]

Hi Fletcher, you must have over heard my cry for help-------------------Sam

[SHADOW]

Bonjour Fletcher,
J'ai fais au mieux pour être clair!!!


Hi Fletcher,
I did my best to be clear!!

Merci Shadow ..

Sam .. here is an animation capture of Shadow's motor driven sim in Algodoo turning CW - it would help him if you describe using the coloured linkages etc what actions, movements, and connections (rigid joint or pivot joint etc) are accurate ..

The opposing heavy drums are connected by solid bars (with pivots) so that when one side moves the other does also at the same time (effectively one unit) .. these cross-bars are not physically connected and slide over each other ..

The red, blue, and green linkages and their connections to what and where need clarification to save time ..
