Please play this video, best set it to cycle...maybe watch for your amusement for a while, though I doubt you'll glean much other than a headache for the trying.
Leave it running to one side, this post to the other, now study the video whilst referring to the following text.
------------------------------------
The geometry at play is simple enough...
We have three spheres turning in a triangle...as shown these are grouped together, each touching the central point along each side of the triangle (black) As they turn these three spheres extend outwards, into the triangle's three tips (grey). The spheres are to travel around/through a triangle here.
The video... https://youtu.be/etg2e8IF-Dw
Stop the video where two opposite shoes align across the 12 0'clock that you're looking down upon. Inside this hollow rests a sphere, likewise two other spheres around...three spheres grouped together.
IMPORTANT...the closer these discs are to each other the easier it is for you to see the action. In this video I've done just that. You'll hopefully be able to appreciate that any sphere of the geometry shown would have to be a severely squashed sphere in this example!! So please bear in mind, at all times for its important at all times, that these two discs are significantly wider apart than shown
The sphere in this hollow is resting on the four petals seen within it.
Straight away...less resting on, more resting in...because the discs are wider apart. Resting such that the sphere is a whisker away from hitting the axle. All three spheres are in this position, all three also just a whisker away from touching each other.
The four petal edges are, at this point, cradling the sphere & they act in pairs...top/left with bottom right, bottom left with top right.
Moving on from this point, the B/L & T/R begin the spiral upwards, taking the sphere with them. The point is reached where both petal edges have spiraled fully up....where these two edges are at 12o'clock.
Once again, remember, the discs are actually wider apart...& the wider apart so the more spheres will sit in rather than sit on.
Here is the same position but wider.
So, on reaching this max point the sphere is not sat atop two edges, it's ready to roll into two aligned cup halves. There it rests until petal sides TL & B/R appear, ready to spiral it back down...to reach our start point.
It may take a while but you'll see it all clearly enough, soon enough.
We therefore have two discs turning in opposite directions, thus two axles if affixed. As they do, so three spheres move in/out from the axle.
These spheres are static though, they are not themselves turning around the axle as they go...and they must.
Referring back to the simple geometry....this device is placed within a triangle, all be it with its tips rounded off. It will then drive itself around this triangle as suggested back there.
I'm not going to claim this a PM device, though I strongly suspect it may be...because this would clearly be a seventh machine to add to the six already known to Physics surely?
A turn in one direction being transferred into a turn in two directions & visa-versa?
As for PM?...it has the required elements for sure. It's inventive and hitherto unimaginable, even though divinely simple.
The answer must include these three elements, si?
No desire to bore you further but two Bessler wheel engravings, suitably arranged in there design, placed on an axle, will facilitate the same principle...not with spheres of course....but, another time maybe?
