The front of a table-top-size pendulum clock. The clock mechanism is driven by springs that are wound every few days by inserting a key into the two holes on the front of the clock. Credit: J. Levine/NIST
The rear of the same clock showing the pendulum and the gears that translate the motion of the pendulum to drive the hands of the clock. The arrow points to a small screw that is used to make fine adjustments to the length of the pendulum so that the clock keeps correct time. Credit: J. Levine/NIST
