William F. Skinner - 1939 Gravity Power

[purelyprimitives]

i did download it but as it was an apple file i could not open it. .

Its actually just a zip file that once unzipped contains an MP4 video that you should be able to play on any computer.

the input

Hi All, The back and forth motion is simply a result of the input which is rotational. The input does not move the levers back and forth, it rotates the translation plate via the swing arm , the offset swinging weights ( down below) cause the rotating upper arm to swing to and fro.
That very top bracket at the beginning of the video where the four swing arms are connected I think must be spring loaded somehow.
That's the last piece of the puzzle, also happens to be the one with the least amount of footage to examine.
Just what I'm seeing.

input lever motion

I am being told that the movement is less back and forth and more rotary, so made a gimbal this morning..it will have an adjustable center since off center in the gimbal should trace an ellipse.

Did you download that video in the zip I posted? It shows exactly what what the motion of the input lever is - its really not even in question. It's right in the beginning of the original movie. The top is mostly back and forth with a bit of rotation and that makes the ellipse.

Centre Lines of Gravity Machine

And thank you Arto for your drawings on this thread they clearly show the input and output shafts in line with each other.

Lower Joint on Gravity Machine

I wish I had looked back at the threads in a bit more detail It clearly shows that the ball and socket joint is coupled . Plan to get working on one of these soon. What better way to recycle a cv joint and a driveshaft and lower suspension hub That should cope with some serious weight.

Lower Joint on Gravity Machine

Greetings from Ireland.

The Skinner machine looks amazing. I am a little confused about the lower joint. Are the two parts of the ball and socket joint rotating freely of each other as in the case of a rod end in a steering rack or are they actually coupled as in the case of a constant velocity joint. It would make sense if they did rotate independently and the ball had an offset from the centre line of the output shaft. Would I be correct in assuming that the shaft that the lower weight revolves around has an offset from the centre line of the output shaft or if you could imagine the output shaft as the centre of a circle, would the ball and socket joint be on the circumference or in line with the centre of the circle? The other thing I would like to know is are the centre lines of the input and output shafts the same or offset. I understand the eliptical part. your replies would be appreciated

the normal hook electronic scales are not very sensitive, they are more designed to measure kilos instead of grams with steps sizes in around 100 grams, and with my models i need to measure grams of force so steps of 100 are not much use.

My idea is to modify a standard scale so that it has a hook, i have done it before. basically i clamp a magnet on to the scales and run a thread over a pulley..

the motor in use in the last video was from a tapedeck, or a cd drive not sure which but it was one of the smallest i had.

considering i was barely drawing a watt, there was considerable torque on the output..this should work well on a pp3...lol

move the nuts up

yes i am a bit short of 10 mm brass nuts, but can more them up no problem...i will add another bearing to the input and tube around the struts so that it wil be rigid..

Now i have a small homemade pancake wind generator that works well at 600 prm , Perhaps i should install that for some current power generation tests........ i would like to do a prony test on the video head ( lol) but have to wait while a sensitive electronic scale ( 5 dollars ) from ebay gets here

I'd actually not add any more of the nuts but first try to just move them all up so they come to the top of the threads and leave them missing at the bottom end of the stock. That will be more imbalanced than if you had enough to fill the whole stock.

Can you give a link to the scale you're getting? I just have the mechanical ones. The ones I have are actually borrowed from Peter.

off balance and indirectly proportionate

Ok changed the top part, and added second weight

very interesting startup or recovery from stall...smaller weight whips the large one

Good job on the progress!

We already know the principles but it is great to see more examples of how the output is not directly proportional to the input. when you lock up the output, the input watts hardly changes. Under a normal equilibrium system, it would have slowed the input, which would have reduced the back emf and the current draw would have skyrocketed until you burned out the motor.

Same principles applies to Jim Murray's SERPS and other electrical machines where you can load up the output without the input really seeing it. They're all universal principles.

Your lower weight looks like threaded stock with some brass nuts. Maybe try moving the nuts up to the top of the threaded stock to make it more top heavy? It will just give it more of an off balanced situation, which increases the tendency to fall - the more off balance, the more gravitational potential will convert to real work.

William Skinner 1939 Gravity Machine Upper Mechanism

ok..the upper shaft may be rotating , but its primary purpose is as a lever. No rotary power is fed in from above. as i see it.

One can see the little driving arm, going around in the rod closest to the camera in the full video.

There is no linear back and forth motion at either end of the top section rod

Now in the one instance, just after the weigh swinging example, one can see the rod passing through the gimbal. Watch the left hand rod in particular. The top of the rod is tracing out a circle and so does the bottom of the rod. The rod does not bend or distort, when the top of this rod is outboard the inner end is inboard the bottom portion of the rod is at all times lined up with the top portion.

The input "lever" on the pivot does not rotate on it's own axis - the only thing about it that rotates is its upper end and lower end is its position in volumetric space.

If you take an egg beater and hold it in your fist so the whisk is down in the eggs, you can rotate it around the bowl so its position in space is rotating around in a circle but it is absolute not revolving around its own axis (it is not spinning in your fist).

The bottom end of the lever is through a bearing in the "translation coupler" so the coupler can rotate independently of the lever. The upper end of the level is through a bearing in a "blade" or small wheel that is rotating and that blade or wheel is spinning on a bearing at the end of a square/flat rod that is simply rocking back and forth. As it rocks back and forth, the small wheel or "blade" at the end of it will give an elliptical rotation to the upper end of the lever that is mostly back and forth. The long length of travel is quite a bit more than the short width meaning it is in a very narrow ellipse.

I see the posts over there and they are not paying attention to the common sense facts that are easily observable from the video regardless of the age or quality of the video.

This video shows it pretty clear - it's right there in the beginning of the video: http://feelthevibe.com/free_energy/s...upperinput.zip

Update v#5

This will be last update for a while, I have run out of spare time. If you want to see my progress, I will put the whole thing on my blog soon. As Aaron has said many times, that all the parts are not directly coupled, there is only loose couples from the shifting center of gravity and mass swing forces, hollow shafts top and bottom. There are many ways to activate these types of actions, the top wobble shaft does moves in circles(restrained epicycloid forces), with elliptical shifts of the forces of 4 pairs of masses acting in natural cycles with the pivot that is also an off center plate, and all of them running free wheel, just how a mechanical vortex should be, the bottom gear gets an even traction from the action of 4 circular swinging levers that just overlap each others counter forces and stopping it from ripping it self apart, this is why you need a locking mechanism at the bottom only, where there is some resistance to the whole thing. I have basically finished the replication project and will only continue when I get more time. Here is my final update. Regards Arto.
