Hi Charlie

Trying to understand your pic in #311.  Is that an orbital gear around the central axis?

Thanks!
No. Nothing that fancy... ;) Its a simple cam and the smaller circles the cam follower. I showed it in phantom because it was mounted separately on the other leg of the stand. The cam lifts the rotating follower (and connecting arm) up lifting both weights. Because of the offset, the bottom one would go counter-clockwise and the top, clockwise. It worked exactly as expected up until around 4:00 where it hit a "wall" and couldn't lift its own weight. The new one I'm working on will only have to lift one weight instead of both which should get me over the wall.
Regards,
Charlie

That is an awesome concept - don't give up the fight!  I was thinking if you mounted an orbital gear offset on the main axle, and two smaller pickup gears instead of cam stops (one on each side) on the slider shaft, you might be able to accomplish as the slide pushes the smaller gear back onto the orbital and forces it back to true (like a pendulum), but this is all in my head and unmodeled - I always seem to hit that same wall in practice.  Keep up the good work.

Peace!

@All,

Forget my gate latch solution for anyone trying to replicate Bob's machine. Got the weight holding units together today with a latch post. But ran into a problem with the gate latch setup. It is to difficult to unlatch under pressure with just 7 lbs and with saved centrifugal force it would be impossible. I will be changing to a regular door knob setup as they open pretty easy even with your body weight pressed against the door.

Hi Larry,
How were you activating the latch? Could you modify it so that there is less of a right angle where it catches?

I was manually sliding the latch mechanism onto the latch rod connected to the 7 lb box. Then lifting it and pulling on the release pin. Very difficult with 7 lbs and at this point my design would have the springs connected to the 7lb box, so the tension would be some multiple. The catch is a small arc. I was looking at modifying the latch catch, little difficult and it may cause latching problems. The door knob latch seems much better at releasing with many times the weight.

Now this baby could sling http://en.wikipedia.org/wiki/Trebuchet.

Sounds good. Will you rotate the door knob to retract the latch?
Regarding the trebuchet, it seems as if its identical to Bob's machine but going in the opposite direction. In other words, Bob is raising the weights and slinging them down and the trebuchet is vertically dropping the weights and slinging the weights up. Hmmmmm. Let me think about this.....

Yes, I'm going to use a cheap non-locking knob and screw a handle to it which will be hit by a stop. But because of the release direction I have to change my design to go counter-clockwise instead of clockwise.

Another observation on Bob's video, when he first starts to brake at the end you see it at the top, then the next one is back down, then the end one at the top. He had talked about maintaining a certain speed for his generator. The video has a low frame rate, so it may be the top clips are just not caught by the camera at the controlled speed. In fact on that second to last one, you can easily see the missing frame, where it appears to be coming up then jumps off to the side.

The trebuchet is very interesting, just think if you intercepted the missile at release point and stored the energy, then used that energy plus gravity for the next launch.

The momentum from a falling object cannot return the object to the top, but how much extra energy is required to return the object to the top? Bob starts with his top springs compressed. I don't expect the sling from Bob's machine to be near as efficent as the Trebuchet but it may be enough to keep it running.

Well here's a concept drawing that I did based on using the trebuchet form. Might be something in here we could use. It appears that it could have the same bone-crushing torque  ;D as Bob's....

Hi Jason,
Thanks. I'll be curious to see what Larry thinks as well. Of course, we don't know if this would work in real life or not. I wish I had a good modeling program but I don't.

Charlie

Very interesting design and quick thinking on your part. I'm on the fence as to whether it will work or not  ???
I'll knex if you want, but the only problem I see is between step 3 and 4, where the end roller would slide thru the weight, but easy to correct.

Sure! Knex please. Maybe that will tell us whether or not it could work. Of course you'll probably have to tweak the weights and arm lengths but if you have time, that would be great!

Sorry Charlie, the Knex is good for modeling mechanical movements, but pops apart with anything but very light loads. So no weight testing, but can run thru the movements of your design.

Knexed. In your drawing we'll call them step 1, 2, 3 and 4.

In 2 the weight catcher is all the way down and the ball is not at the top. It will continue to try to push the weight catcher down until the ball is directly over the pivot.

Inbetween 3 and 4 the Roller End slides thru the weight notch out the other side.

Inbetween 4 and 1 the levers jam. If the ball end of the arm is on top, to be able to pass over the weight catcher then the weight catcher arm will run into the pivot. Also, would jam if reversed.


@Jason,

How are you coming with your cad study? Any recommendations?

Hi Larry,
Thanks for the review. As I was thinking about this, this morning I realized the problem with the arms but I have designed a way so that none of the arms interfere with each other. Also, I thought up a different scheme for the larger weight which make everything easier.
I've decided to shelve my last design in favor of this one because I think it has the most promise and have started to build a model.
I'll keep you guys posted of my progress.
Regards,
Charlie
