A great ball contraption ferris wheel is a rotating series of cages, sweeping in a ball at the bottom and dumping it out at a high platform that tips cages. It can function as a clocker, but requires a wide footprintDavis.
A variation is the ferris lock. The idea is to use a long tray or "stretched cage" attached to a wheel or large gear. It can scoop at the bottom of the cycle, and dump into a linear tray or chute at the top (lifts half a cycle, or one diameter, assuming non-pivoting tray with three sides (only the roof open)), or it can rise from under a bin and tip out near the top (lift only 1/4 of circle, assuming non-pivoting tray)Davis.
