Function of a pendulum clock 1:
This movement shows what the actual timer for the watch is and that a watch counts the number of periodically repeating processes:
The middle weight (1) pulls on the peculiarly shaped gear (2), which is prevented from spinning by an anchor-shaped escapement (2). The pendulum (3) releases the escape wheel in equal periods of time. The strange shape of the gear and the anchor escapement ensure that the pendulum is supported in every phase when swinging back and forth and neither stops nor swings further.
Function of a pendulum clock 2:
The rest of the clockwork is used to save people from counting the pendulum oscillations.
The shaft (4) turns once an hour over some gears and turns the minute hand in the tower once every hour. The hand mechanism has a ratio of 12 : 1, so that the hour hand moves twelve times more slowly.
The quarter-hour striking mechanism (5) is triggered via the pin and lever, which in turn triggers the hourly striking mechanism (6).
