The cuckoo clock from the Black Forest is a mechanical pendulum clock which is driven by a weight in the shape of a pine cone. These days 1-day and 8-day movements are common, meaning that the weight has to be wound up daily or every 8 days, respectively. Adjusting the clock takes place via a shiftable pendulum bob that is usually made in the shape of a maple leaf.
The mechanical cuckoo that chimes the hour is driven by a second, independent weight. When each full hour strikes, a sophisticated lever mechanism moves the so-called perch forward where the cuckoo sits. A wire arm opens the door and the cuckoo appears. Slightly delayed, the cuckoo call is then imitated via a bellows and 2 pipes.
The cuckoo is going to appear again in x minutes. For those who don’t want to wait that long, the cuckoo can be lured out here…
