The inside mechanics of cuckoo clocks maintain virtually the same design since the day they were first created in the Black Forest of Germany. While the parts are now sometimes made out of metal and plastic instead of the all wood versions that started it all, the weights and counterbalance mechanisms that help them perform accurately and to imitate the sound of the cuckoo bird have not changed much in almost 300 years. A mechanical movement run by weights that hang from the bottom of the clock drives the action of most cuckoo clocks. Most clocks have three weights, while some larger more complex versions require three weights hanging from the front of the cabinet. They are commonly in the shape of pinecones and must be pulled periodically, depending on the model. Spring-driven cuckoo clocks never really caught on and subsequently are quite rare.

Black Forest cuckoo clocks run on a set of wheels that lock gears and provide the power necessary to swing the pendulum back and forth. Every time the pendulum makes a complete swing back and forth, one tooth of the wheel is released from the escape wheel. Each time a tooth escapes, the time train moves forward, resulting in a very small movement of the minute hand. When you first bring your new cuckoo clock home you will need to test its timing against a battery operated clock of some kind. If you measure the difference in time between your cuckoo clock and �real� time, you can then adjust your cuckoo clock to perform more accurately by adjusting the weights that hang beneath the housing. It�s always an educated guess rather than an exact science, and old fashioned cuckoo clocks are never one hundred percent accurate, but patience and readjustments made every twenty four hours over a few days will get your clock functioning as close to perfection as possible. The standard rule of thumb is to try to get your clock to miss only a few minutes per week and live with it.

Since the beginning of civilization, humans have searched for a reliable way to keep track of the time. In the earliest days, months, seasons and years were tracked by careful monitoring of the phases of the moon. Later, the sun and stars were also used to help early people track the passing of time.

The Sumerians used the sundial to divide days into two-hour segments. The Egyptians created a device called Cleopatra�s needle to divide their days into two-hour segments while the ancient Romans devised a way of dividing time into night and day.

A pressing need for more precise measurements led to the invention of the water clock and then the hourglass. These inventions were limited as they relied on water and sand, respectively, to function. The search continued to search for a way of tracking time independent of the seasons or nature.

In 1582, Galileo discovered that a pendulum could be used to track time. He drew the first designs for a grandfather clock, though he did not build it. Finally, in 1656, Christiaan Huygens built the first known grandfather clock, putting Galileo�s discovery to use. Though the clock did not keep accurate time, it was a major breakthrough in timekeeping technology. Through the years, various inventors tried to improve on the design, but with little luck.

Finally, in 1670, William Clement discovered that the clocks worked better with a longer pendulum. Of course, this required a taller clock. Clement named his newly designed clocks long-case clocks. This was the predecessor of the grandfather clocks that we know today.

In 1875, Henry Work wrote the song �My Grandfather�s Clock� and the name stuck and finally, after many years in the making, grandfather clocks were born.

Today�s grandfather clocks rely on a pendulum attached to an anchor. The swinging pendulum causes the anchor to turn a gear, which in turn causes the clock to tick. A pair of weights further helps power the clock and keeps it from losing time. Although the technology has evolved over the years, the grandfather clocks of today still reflect the ingenuity of human�s earliest ancestors.
