Just
below the plaque is the access door for the insides of the pipe organ.
This is the only way most of the pipework can be accessed, and requires
a bit of agility to get to it. In fact it literally requires
a
crawl to get to the light in back, hence the term "organ crawl"! |
|
Straight
back from the small access door is the blower for the pipe organ. The
3/81 date in the "housing" field matches the 1981 date on the console.
Zephyr Electric Organ Blower Co. is owned by Schantz. |

Here's
a view of the equipment under the organ. On the far left is the lever
system for the expression shutters on the Swell box. The two large
boxes in the center and on the right are the two main air reservoirs.
Air comes from the blower and goes directly into these reservoirs,
which then distribute the air to the wind chests under the pipes. |
|
This
is a better view of the wind reservoir on the right in the photo above.
The large gray pipe, which looks to be about 8" in diameter, leads from
the blower to the reservoir. When the blower is running, the reservoir
will fill with air and expand. In conjunction with the size and speed
of the blower, the springs and lever device apply resistance thus the
"wind pressure" for the pipes. The reservoir of air will compress and
expand depending on how much air is needed by the pipes. |

This
wiring board is mounted on the outside of the Swell box. Note how
clearly things are marked. This will make someone's job easier in the
future if they have to resolve a wiring issue. |
