A great ball contraption clock lift mechanism was proposed by Steve Hassenplug and defined by Brian Davis. "Picture a slightly tipped-back clock face, with a 'C' shaped cup on the end of the minute hand. At the bottom ('6 O’Clock') it scoops a ball (or balls) into the cup from a bin, rotating them up the face of the clock. Near the top (say between 11 & 12 O’Clock) the face is cut away, allowing the balls to fall out and into a chute or receiver." It is arguably the same as a wheel lift.
