Getting over the top part 1

[whatzonstrat]

Getting a single weight over the top.  We’re all familiar with the single weight on the rim of the wheel, ( weight W ) as per  fig.1 when let fall from 12-00 will go around and stop somewhere after 11-00 as per fig.2 .    So how to give a small amount of additional torque to get the main weight over the top.  The amount of torque to achieve this is quite small, I have found by experiment.     In ref to figs.3 &4.
A nail or pin is fitter to the wheel as per fig.3 and a mobile weight with a loop is manually hung on the wheel as it rotates past 3-00, and removed as it passes 9-00. (Fig.4)This weight is quite small , maybe about 1/4 of the main weight, or less.
So if you keep applying this weight at 3-00 and removing it at 9-00, the wheel slowly accelerates  and gets faster to about 1 rev in 2secs or so, and will continue to accelerate until it gets too fast and difficult to keep putting the weight on and off without dropping it or missing the nail.  ( a working wheel ! LOL ).  So we need an auto system to apply a small amount of torque at 3-00, and remove it at 9-00.   I have tried several systems, one of which I’ve shown in figs.5&6.   These drawings are not accurate and the amount of movement was a bit less than shown, as I used a larger weight near the centre, to get the same resulting torque at the rim, as the small weight on the nail.  So the weight is at the wheel centre to start with, so effectively off the wheel,   and swings out about 3-00 as per fig.5 to apply additional torque at 3-00 which travels around and swings back to the centre at , or just past 9-00 as per fig.6.   But this system did not work and no acceleration at all,  like trying to push water uphill with a rake !!  
When I was manually putting the weight on and off, previously , and as the wheel got up to some speed, you could shift the point of on and off to putting on at about 4-00 and taking off about 10-00, and the wheel still accelerated. 
So as the wheel gets faster the point of weight on /weight off seems less critical .
Why did my system of lever and W2 not work ?
ked out of the wheel.
I thought this was close to the manual weight on weight on/off

Your image is too small. I cannot read the writing.

In saying that gravity is quite predictable. If you insert a weight at 4 and remove it at 10 the wheel will decelerate. The weight needs to fall further than it is lifted to give its energy to the wheel. The same goes for 3 and 9. The weight has to go on before 3 and come off before 9. I suspect the timing inaccuracy and unaccounted forces of your hand may have been accelerating the wheel.
