A few years ago I figured out a mechanism that allows the weight to pull itself inward as it ascends, then on the descending side of the wheel it flips outward. It didn't work too well but it is an interesting example of what you can do with weights and levers.
(If you want to see it, it's in Scott's "Ideas" section. Look for 'MrTim's Lever Arm'. Sorry about the drawing (it's not the best quality.))
