Chinese Buddha sculpture) allowing the bucket to tip over spilling its contents. As it falls, it trips a lever connected by a cable to a catch on top of the water wheel which is released to allow the wheel to rotate. However, by the time it has moved on, the catch has returned to its position locking the wheel in place so that the next empty bucket is now under the water flow to repeat the cycle.

The complete sculpture is rotated by the water underneath it swirling in a clockwise direction when viewed from above. The rate at which it turns is regulated by a "catch" device on the pontoon edge that locks into one of the 60 stops secured to the wall of the inner pond. Every 12 minutes the catch

This clock uses 20 counterweighted buckets that are free to swing and are mounted around the edge of a wheel 2.3 metres (7.5 ft) in diameter. Water supplied from a meniscus-full tank runs into a bucket at a constant rate until the weight of water in the bucket is sufficient to overcome the

The 5 m (16 ft) pendulum mounted on a knife-edge to minimize friction and is kept moving by the "top drive" (the top moving glass chutes); as one side becomes full, it tilts the mechanism over to its side so that the water is discharged and the other tank receives the water supply

In this example, two tubes on bearings are arranged so that they overbalance when full, thereby dumping their contents into the pond and returning to vertical under the influence of a counterweight at which point the cycle starts over. The counterweight is in the shape of a

Seconds are marked by the rotation of the glass wheel which has 30 pins around the edge. Each half-cycle of the pendulum (2 seconds) results in the wheel moving to the next pin so it completes a cycle every minute. A
