Austin Organ Co. - 1913

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!
