The cog wheel with eight pins is located at the end of the weight drum for the striking train. The eight pins are spaced equally around the edge of the wheel. When the wheel turns, a pin pulls down a release lever that is connected by wire to the hammers of the hour bell. When the pressure of the pin on the lever is released, it jumps up sharply and the hammer strikes the bell. |
