I think the lever's pivot needs to be like a roller or small wheel so when the lever goes up and down, the roller would also cause the pivot point to move side to side.    If what I vision, and it works, this is really very simple.  I will have to get some parts, but this looks worth a try.

I am still not sure what to do with the outer end of the horizontal lever? Put it on a spring or what? (This is actually the reason I'd like to see Aristrikers setup )
It may have indeed have similarities to the mentioned Veljko Milković device http://www.youtube.com/watch?v=dvst47E5CvM, ,although one can see that the energy put into the system would be much weaker, however one would need additional constructions.... hmmm, but thats not exactly what is proposed here from 'protech' I assume. Milkovic has no rolling carriage.

@gauschor That is a very telling video thanks for posting it, it shows the assembly can do work without upsetting the swing of the pendulum, but notice, this is 'in-line' with the swing of the pendulum. In protech's initial suggestion this will transpose as the carriage. Which as we can see from the video can do work. He (protech) is suggesting adding an additional lever at the top to extract work from the up and down portion of the pendulum swing. Effectively doubling the output of the Veljko Milković device. Or using one (lever) output to keep the pendulum moving while, at the same time, extracting work from the carriage output.

Also The movement is the same as my observations last night, the lever arm does a 'double bob' on each swing

@maw2432 I have seen that video before, correctly timed shifts in the axle builds bigger swings. Just like your hand when swinging a ball on a string

@nightlife I have enclosed a picture of what I mean, hopefully it is clear enough.

Initially I thought this was a device to maintain a pendulums circular orbit around a fixed point, after watching gauschor's posted video, I am now not so sure. Maybe just maintaining a gentle swing will be sufficient and no heavy industrial parts will be required.

I need to construct my carriage and start from there, trying various combinations of pendulum and carriage mass, THEN add the lever to help maintain the swing.

Any thoughts?

Actually I also think that a circular orbit of the pendulum should be maintained when I look at protech's sketch, and not only simple swinging movement :| Can't say for sure now that 2 possibilities are given *scratching head*

Maybe it is additive and if left to run will form full orbits (as shown in the video posted by maw reply118). If a portion of this is extracted to do work it will only maintain a swing.

These are all just assumptions though.
