I do not disagree with your post , mine just came to late ,
what will the length of the pendulum be to be able to period at 26 rpm . Also , from a slight push by hand , what will cause the pendulum to be crancked for a complete cycle , it must complete a full 180 deg before it will swing in the intended direction , from the crank of the shaft the wheel will need to turn 180 deg else it will fall back to the rest position . |
Lets not forget that Bessler's wheel didn't need the pendulums to run. If you are trying to use the jerk of a pendulum. You will have to time it to the required shift time, or it will not help. If you are trying this I would suggest a leaf spring or bow shaft type of pendulum to get a accelerated swing back for the shift position.

jim_mich ,
I can only think of one reason why the axel was 8 in in dia , and that is to guide poles or some sort of link from one side to the other of the wheel with the weights on their ends , it is the only way to stabilize them like in mt 70 ; 71 ; 72 , it is also the only way to get overbalance , to move both side weights in one direction , one closer and the other away from the axel .
rasselasss ,
If the pendulums were on the main shaft and driving the prime mover , the wheel could have been on two bushings riding on the main shaft but not connected to it , but to the weights by means of chain or cord , so it could have a constant speed and the main shaft a erratic rotation caused by the pendulums , but why would he use pendulums if the wheel was so heavy , he could have used flywheel inertia .

D/MAN,i looked at the idea of the wheel rotating freely on its own bearings with the shaft providing an unknown mech.to enable the wheel to rotate....the friction of the wheel alone will not produce work at the work end of the shaft(maybe your thoughts are different to mine on this or i just can't see it)...For illustration only i cold bent a spare shaft on my set-up (its not completely true ,running between vee-blocks but good enough for illustration)the 360 degree throw of the crank would equal my weight shift total movement on the spokes required to give rotation....on the shaft end i attached a simple lever to simulate Bessler's drawing of the pendulum attachment....the advantage i see is the wheel and lever at shaft end can be adjusted to suit the crank throw to his unknown shifting mech.....if my own ideas fail i'll look at this in more detail....D/MAN or anyone if you have any imput i'm very gratefull its only by collusion and sharing that Bessler's mystery will be solved...Thanks.

rasselass ,
In your drawing , i see the small arm with a rod pivoting on it's end , for now I see just a crank shaft , but rig a pendulum onto that little shaft and try to turn the wheel so the pendulum is driven , get a nice easy speed going and slow the wheel down/ speed it up just a fraction , the pendulum want's to swing at it's natural frequency wich will cause the wheel to stop dead at the pendulums apex , unless you have a variable rod to compensate for different speeds of the wheel .
In the loose wheel arrangement the wheel is tethered to the shaft via strings via the mechanisms , it is just floating , like in the Keeny Wheel , it is able to run for very short periods faster or slower than shaft speeds .
