Windchest - part of the air system within the musical mechanism. It is a wooden device that collects the air produced by several bellows working alternately. When one of them is discharging air into the windchest, another is taking air into its chamber, and vice verse. This ensures a continual supply of air from the working bellows. The windchest is also fitted with valves that are opened by a system of wooden poles and push-rods in accordance with the pattern of pegs and staples on the barrel. When these valves are open, air passes from the windchest to the pipes of the organ. |
