Ferris wheel

From The Great Ball Contraption Wiki
(Redirected from Ferris Wheel)

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. Can function as a clocker, requires a wide footprint.[1]

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).[1]
