Tucked
away in the
front corner of the Great Division is the Zimbelstern, one of two
percussion on the organ. The Zimbelstern has bells which are struck in
a somewhat random pattern, bringing a different sound dimension to the
organ. This was added to the organ in 2010. |

The other
percussion in the organ
is the Chimes pictured here. Chimes are often played by themselves, or
coupled to other parts of the organ. A relatively small part
of
the instrument, it can give the organist a nice addition to the overall
sound. This was added as part of the 1988 rebuild. |

Each
pipe sits on a
chest which is fed by a reservoir which regulates the air from the
blower. Here we see a reservoir for the Bourdon rank. Pedal
pipes
need a lot of air, so it's common for organ builders to put each rank
on its own reservoir. The top of the reservoir is extended indicating
the blower is on.

Under the
pipes of the Great
Division is the main air supply pipe coming up through the floor from
the basement. This pipe has obviously been modified over the years due
to the many rebuilds. Metal wind lines are common on older instruments,
however today many builders use plastic. |

In the
basement of the church in
its own room with plush wall-to-wall carpet is the blower
which
supplies wind for the Great, Swell and Pedal Divisions. The blower,
which came from a W.W. Kimball instrument in Cleveland, Ohio, was built
by Spencer Turbine in 1921 and
refurbished in 2016. Spencer is still in business today and provided
parts when the blower was rebuilt. The high gloss
black paint give it quite the striking appearance. The only thing
missing are flame decals on the side! |
|
Here's a
look at the builder's
plate for the blower. A three horsepower blower is quite substantial
for an instrument of this size. The box showing Wind 8 means it's
producing 8" of static wind pressure. The actual amount of wind being
supplied to the pipes is controlled by the reservoirs connected to the
rank.
