Calcanten bell
The Calcanten-Glocke (also: Kalkanten-Glocke ) is a historical stop with which the organist gave the bellows treadmill a signal to start filling the bellows with air , which made it possible to play the organ.
Original function
If the bellows of the organ's wind mechanism had emptied of air after a long break, the organist gave the calculator a sign to fill the bellows with air again. The physical process of creating naturally resulted in a short delay, so that this sign had to be given a certain time before the next use of the organ . This made the calcareous call all the more important for bellows treaders who fell asleep during the service or moved away from their position. An acoustic signal was given by a small bell by means of a bell.
Technical renewal
After the introduction of electric centrifugal fans , the on / off switch takes over this function today. The typical lead time of an organ remains the same. On some historical organs, the original limestone train is still preserved or restored during a restoration true to the original.
