1939 Gravity Power - multiply power by 1200%

[shylo]

Hi Luc , Wow that's alot of work! The drive I found has to be free to move. You have it locked .I wish I could express myself better.
I think the input only rotates upon its' axis ,while being driven back and forth, the eliptical movement is caused by the rotation of the lower masses which are independent of each other, but push force back at the input , when timed properly can add.
I did some testing today ,I ran a generator off the output for 5 mins, one with the drill connected to the output pulley, the other with the drill connected to my skinner attempt which was connected to the pulley.
They both consumed the same amount of battery life, and the both put out the same amount of watts.
Should the skinner device not use more power since it has those extra gears ,and levers ,and bearings to deal with??
My build is very poor quality ,just trying to see ,but it requires more effort to hold the drill without skinners' apparatus , than it does with it.
I can hold the input (drill) solid or let it follow its' own path , get rid of the sprocket and chains and hold the drive in your hands you'll see what I mean.
I believe there is something here ...artv

Hi Luc,

Just as something to try real quick with that setup,, could you stop the outside short arm piece from rotating while you turn your gear?

If that pivot shaft was solidly connected to the arm and stopped from rotating that would hold that outside arm still and make the oval.

Think about it first,, I would not want you to take up to much time with it,, but it could be run with like a tiller in track maybe.

Hi webby1

I'm away from the workshop for a few days.
It would work a little if there was load on the shaft but don't think anything can be done with it for this device, unless I had a mirror gear.

Thank for trying to help

Hi Luc,

I can see you got into a jam. This design should work (no guarantees) it is a slight modification from my Hyperbolic Drive design, it will produce ellipses and many other interesting permutations from eggs to all form of hypercyclic shapes and patterns, the requirement would be a variable speed on the second sprocket/gear/pulley/directdrive. I have drawn it as a 1/2 speed form, which gives an ellipse, this would be easy to adapt using chains etc. The original Skinner design would be very similar to what I have here. The drawings are quick sketches, just adapt your materials to suite. I hope this helps with your build, regards Arto.

Wow!...thank you Artoj for doing all this work

Quite an interesting mechanism. I will study it and see if I can build it with the stuff I have.

Thanks for sharing and taking the time to do all this

Interesting results you're getting

I've already posted a few days back that I disconnected the upper lever drive sprocket and turned it by hand. That's how I concluded elliptical may be the way.

Altho not quite as good as Arto's idea above, if you have zero tools it could be simpler.

Bare bones idea, estimate what you need and adjust with screws to measurements.

Take a tap drill and make a top plate out of some aluminium, that way you can screw in some common sprocket shaft from below, take another and make one underneath.

Screw and add nut and bold adjust. You may need to machine another set of slots for those bolts so that all becomes easily adjustable ( forgot about that )

Print a stencil and drill some plexiglass or w/e material you can get.

I think you can make this pretty low profile and with minimal tools, I think you can make this cheap if you go chinese

If you take small 1/20 hp motor or even smaller, the goal will be to eliminate any useless weight, that way we can approach ideal situation.

What will next step be Gotoluc, this is but a fraction of the whole remember, Skinner aint the type to waste money...
