Title: Stopped organ pipe controlled by pad at lip - has control mechanism outside air channels to obviate need for seals
Inventor: ZACHARIAS ERNST
IPC: G10B3/06
Filed: 1975-10-18
Abstract: The supply of wind to an organ pipe is ordinarily controlled at some point along the wind channels supplying the pipe: since the controlling impulse originates the wind channels - at a manual or the pedal board - the mechanism breaks into them at some point, and sealing arrangements become necessary. For stopped pipes the air supply is cut off at the point where it leaves the wind channels, namely, at the lip of the pipe. The controlling mechanism can then lie wholly outside the wind channels, and sealing arrangements are no longer needed.
