The tower clocks rings bells at the quarters and the
hour. The sound of the old bells is better heard in the Winter Palace
courtyard than on noisy Palace Square. In the course of the hour there
are twin chimes from the quarter bells, while its end is marked by
the striking of the hour bell. For the chimes to be on time, the mechanism
needs to be "primed". To do this the going train sets the
chiming train in motion ahead of time through a system of levers.
As a result the locking lever (red) rises from a groove in the count
wheel and releases the chime mechanism. This completes the preparation
stage. The clock begins to chime the quarters. In the diagram the
successive operations of the clock mechanism are indicated by numbers,
while its elements are distinguished by colour. |
