Impact can be absorbed by springs. This will spread the force over a short period of time while the spring compresses and decompresses as it bounces the weight back in a reverse direction. If the weight hits an 'anvil plate' on the spring then you will hear the sound of a weight gently hitting something within the wheel.
By using a spring you get a gentle impact that does not beat the wheel to death. It is a perfectly logical method of transferring motion of fast moving weights into wheel motion.

Yep. Thanks for that. I can see now why one must NOT use a spring. It isn't the third derivative one needs to invoke, it's the fourth. The third involves the superforce which acts at right angles to the force governing linear velocity, the fourth, a super-dooper force acts at right angles to the third.
If you hadn't talked about "the sound of a weight
gently hitting something within the wheel" I wouldn't have seen that.
The word "gently" gives the game away rather.
You can't make an omelet without cracking eggs.
Funnily enough one comes across the fourth derivative in structures, (d^4)x/d(y^4). I can't remember offhand what it referred to - change of beam slope - or something like that.
The reason that (d^4)x/d(t^4) impact is so important is that a hammer blow immediately conjures up the vision of a material being triaxially compressed and spurting out sideways. Think of a jet of water running into a sink and squirting out radially until it meets it hydraulic jump.
This turning through a right angle is an essential component of devices such as the Ventomobil which can sail, counter-intuitively, directly into the wind and also sail rather less interestingly faster down wind than the wind itself which is what one wants in the case of the Bessler, of course.

I think it highly unlikely he cobbled together some arrangement & an unknown force producing OU energy trickled out the bottom for him to amplify & use with imagination - we all want that Force on a collar & chain but first we need to decide on the breed of dog, one that's going to be loyal & obedient & doesn't need feeding, LOL.
We have that "Force". The stamping force of (d^4)x/d(t^4). The force of the drop press of the hammer on anvil.
The reason we find it difficult to recognise is that we fail to see that force is an alias for strain.
(d^2)x/d(t^2) "force" is an alias for one dimensional strain (acceleration)
(d^3)x/d(t^3) is an alias for two dimensional strain (jerk)
(d^4)x/d(t^4) is an alias for three dimensional strain (anonymous, let's say stamp and then all the rugby players will know what we are talking about).
How can I be confident this is correct?
Because I have met these three impostors before in the
three equations of state for water vapour.
viz,
P = a constant x T^4 for steam vapour.
P = a constant x T^8 for water vapour.
P = a constant x T^12 for ice vapour.
where P is vapour pressure and T is the phase offset temperature.
I effect the three phases are subject to one, two and three order Casimir pressures.
And when you think about it what could be more reasonable that Bessler should imagining hammering the wheel down on one side in a continuous flow would produce perpetual motion. Any layman would recognise this as a plausible action to take - which is why Bessler was so worried that his "secret" was too easy to discover.
The whole thing reminds me of that wonderful episode with the Beach-master and the Bren gun carrier in The Longest Day.
:28:21
For heaven's sake,
get that carrier off the beach! :28:28
lf you can't drive it, carry it!
:28:49
Down, Winston. Down, Winston.
:29:27
-Hold it.
-Can't you get your finger out?
:29:30
What's the matter?
:29:31
Engine won't start, sir.
Full of seawater, I think.
:29:36
My old grandmother used to say...

...anything mechanical,
give it a good bash.
:29:41
Try it now.
:29:46
Thank you, sir.
:29:47
Off you go. Good luck.
:29:53
I'm sure that got it out.
:29:57
That's what I call a hell of a man!
:29:59
Aye, I like his dog too.
