The
final five photos of this page show the following: 1) A wide-angle
view of the inside of the air chest. Austin is the only company that
builds a walk-in wind chest. They call it their Universal Wind Chest.
Most wind chests are no taller than a foot or 1 1/2 feet in height.
The left side of the picture is the bellows that expands and contracts
to meet the changes in demand for air. This system was invented to
provide a rock-solid supply of steady wind. 2) A fish-eye view from
the other side of the chest. The air lock is on the left, the bellows,
on the right. 3) A fish-eye view of the chest, with the bellows directly
behind the photographer. Pictured are the a) wire harness that goes
to the many magnets located in the ceiling of the chest; b) the grate
on the floor is the wind supply coming from the blower; c) immediately
above the floor, to the left of the air lock, are a row of magnets
that wind a set of bass (larger) pipes just outside the wind chest
d) the small room to the right is the air lock that allows one to enter
the chest while the organ is on. 4) This is the air lock. The valves
in the center of the door allow one to pressurize or de-pressurize
the chamber, depending on whether one is coming or going. 5) A view
of the ceiling - the small bellows at the top of the photo are the
pneumatics that pull on the wood trackers that run from them. The white
circles are the valves that sit under each pipe. The metal bars that
run right-left in the picture are the stop actions. In this photo,
the stop bars are between the note trackers and the bottom board. When
the stop is turned on, these bars flip from near-vertical to a horizontal
position, allowing the key action to use it as a leverage point. The
valve is then pulled down when a key is played. The stop action for
the stop at the very top of the picture is in the "on" position. When
a stop is turned on and a note is played, the valves are pulled from
the board above them, and the air from the chest flows up into the
pipe, producing a beautiful tone!
