Curving Jack

[Jonathan]

Thanks. For a second I though you didn't get it, but there is more to your attachment than there seemed. I've built two models, with the angles between the long and short lever arms on a given lever being 135 and 90. I'm going to build more, where angles change along the length, and where angles alternate, in a fashion; all levers angled one way will have a given angle, all levers angled the other way have a different angle.

Both of those locked up after a few quadrilateral units. I tried making the length of the long leverarms vary along the length of the jack and that was interesting and hard to describe, but of course the range of motion was reduced. As an aside, I also made all the lengths in a given unit the same length, so that it is just a Hoberman mechanism again, but then varied that length from one unit to the next, so that it is like a Hoberman-ated MT138 jack. It's movement was much like looking at a spiral graph and zooming in or out; it retained the scaling properties of the Hoberman mechanism.

I woke up today and this popped into my head, it may interest some of you. It is shown as eight links, but of course you can continue the pattern. Each vertical link is independent of the diagonal ones, and the cross braces. The two corners with cross braces indicate that the diagonals at the ends of the cross braces are attached to each other to make a bell crank.

To clarify, here's another position.

Since I've been making scripts lately, I gave this a try, it's a Hoberman circle. Enjoy!

Jonathan...

Exquisite! It sort of reminds me of a flower blossoming. I'm not sure what relevance this has to Bessler's wheels, but they are fascinating to watch in motion.

What are you using to make the scripts for these? Are you just using one of amateur's "rebuild" codes? Or, are you somehow writing the script directly? It would be nice if WM2D had some feature that would allow us to directly access the script of a model we make so that we could post it for others to play with...

Thank you, I had a lot of trouble around the "beginning"/"ending" of the chain (at 3oc), I'm glad it finally got it working, it was worth it. I type the scripts in Notepad, they're practice pieces as I'm learning computer programming.
The toy page says something like '5. childrens toys in which there is something extraordinary for anyone who knows how to apply them differently', and somewhere else in MT Bessler assures the reader that there is something special about the stork's bills. This circle could be characterized as a different application of the E-toy/stork's-bills. In addition to just being neat, you may also notice that subsections (1/8) of the device could, individually, give you a novel way of changing the radius of application of weights. All you need is two slots, two bent levers, and the angle between the slots must be equal to 180° minus the angle in each lever.

I see you have thought about what I proposed as the scissors system in a circle.
I like the name change too.

If energy can continue around a circle, then the loss could be so little that the force applied will be enough to send it's energy forward, and gravity will have the least effect on the applied force from the source.
The scissors system copies the effect of energy transfer like that of the ocean wave.

I think a gravity system will work in the circle path as the curving Jack unfolds and refolds into and out of balance, by the force of falling weights

Nice find path_finder
However this is the simplest proof that weight falling to one side of a wheel can not ever climb up the ascending wall.
Nice to see you are working on the gravity system.
I myself have discoveries that are working.
