1939 Gravity Power - multiply power by 1200%

[Craigy]

didn't realise you had no universal joint, no wonder. Should be a whole lot better with it.

i think there is bearing on mid plate,lever is not fixed to plate,but in video you see the result of sincronisation
and the force needed to pull the plate is bigger if there is no bearing

I can't tell from the video , but is it possible that it is not a set screw , but a grease fitting?
The input drive  ,I think is quite obvious, rotating while moving in an orbit.
The lower shaft  has to be able to rotate in the plate, but also moves in an orbital pattern not opposite of the upper but offset by ~ 90 degrees.

  The inclination of the upper shaft is approximately 7.5 degrees, whereas the drive plate is horizontal.
The upper shaft therefore passes through the plate at this angle, The rod is fixed, set screw or weld,
what ever, as the weight hangs from this connection so must be firm.

Centraflow, your drawing is right on.

Should show circular motion, not back and forth


No self align bearing


Weight shown on wrong side of plate


No CV joint in William's machine

The motion is eliptical, you are probably right on the self align bearing, probably only a greased bush, the weight I would think would be opposite to the lever rod and does seem so in the video when he moves it by hand.


Not a CV joint as we know it, but I would recommend one now along with a thrust bearing to take that weight, things have improved a lot since 1939. What ever he used at the bottom, the casting is quite high, will have to look up what was available at that time.

Here is the update with the device using the universal joint on the bottom shaft.

The device performs more like seen in the film but the load is still reflected back to the prime mover. I tried everything I could think of and finally decided to take the upper lever out of the circular drive and turn it by hand while the bottom generator is under load (bulb).

By turning the lever in a circle motion I could feel an equal pressure throughout the 360 degrees and the bulb load would not light.

By turning the lever in an elliptical orbit the top weight would fall and cause a change in angle to the mid plate which would make the bottom weight swing around and the bulb would light for that moment. There is a pressure point at the turning points of the elliptical orbit but there is also an acceleration when the top weight falls, so it may come close to being neutral to the prime mover (other than friction losses) but this remains to be tested.

Now looking for recommendations on how I can easily convert my top gear so the lever is turned in an elliptical orbit to further test this possibility of being the right thing.
