The bottom supporting chassis of the big Wurlitzer Style 32 Concert
PianOrchestra is shown during the machine's meticulous rebuilding
in Art Reblitz's Colorado restoration shop. About half of the major
mechanical components are assembled and in place.

Side view of the piano harp with piano action fitted up to the new
replica main pneumatic stack. The original piano stack, which was
in poor condition, was used as a pattern for building the new unit.
The piano can be turned on or off, and has loud and soft pedals.

The famous Wurlitzer Roll Changer (Philipps Revolver Mechanik),
which holds six multi-tune music rolls and plays them in rotation.
The friction drive (at right) allows for adjusting the music tempo.

View of the new main stack viewed from the rear, showing the individual
motor pneumatics and lifting rods that push up against the piano
action whippens, causing the piano notes to sound.

The roll changer is at the left, and to its right the piano harp
can be seen peeking out from behind the roll changer back-panel
and large wind duct. The bell action is partially visible at far
right, just above the flat-belt speed reduction countershaft. The
rewind and rewind to play-trip linkages are at center, below the
roll changer.

The register control unit turns on or off the various music registers,
such as the piano, various ranks of pipes, bells, xylophone, and
drum soft mechanisms. Special control perforations in the music
roll trigger the lock and cancel valves, thereby turning on and
off the associated musical effects.

Front side view of trapwork, consisting of (left to right) tambourine,
triangle, snare drum, castanets, and bass drum (partially visible
behind the snare drum) with cymbal and kettle drum effect. The trapwork
control valves are an integral part of the register control unit,
which is located directly below and in front of the trapwork.

Backside view of the trapwork. At left is the bass drum, with soft
and loud stroke effects. The two smaller beaters on either side
of the large central bass drum beater are for the kettle drum effect.
The xylophone is to the right of the bass drum, and above the snare
drum and tambourine.

Melodie Violin range pipework, seven ranks (front to rear): (1) Wooden Harmonic
Piccolo, (2) metal Clarinet, (3) metal Violin (commonly Gamba),
(4) stopped metal Flute (commonly Quintadena), (5) wooden Violin, (6) wooden
open Flute,
and (7) wooden Violoncello. The control ventils (valves) for
each pipe rank are located in the box-like enclosure
at the right of the pipe chest. Notice that for a compass range
a little more than the top octave there are two sequential pipe notes,
situated back-to-back, for each valve
block.

Bass pipework, four ranks (left to right): According to Wurlitzer
the ranks are (1) Saxophone (metal reed--commonly Fagott or Bassoon),
(2) French Horn (wooden stopped flute--commonly Gedeckt), (3) metal
(and wood at bass end) Violin
(commonly Gamba bass--this rank is a continuation of the Melodie Violin
Gamba pipes) and (4) a large wooden Violoncello rank at the
rear.

The orchestra bells and their striker action is mounted directly
underneath the top main shelf, which on its topside supports the
trapwork and the heavy Melodie Violin and bass pipe chests. The large rectangular
wood wind trunk to the right of the bell unit delivers wind-pressure
from the pressure feeders to the two pipe chests.

The feeders (or pump bellows) located at the bottom of the PianOrchestra
create both a vacuum (to operate all of the control mechanisms and
pneumatic motors, and wind-pressure to blow the large array of 314
musical pipes. The smaller bottom set of bellows create the vacuum,
the upper produce wind-pressure.

A frontal view showing the complicated interior of the big Concert
PianOrchestra. At the top is the roll changer mechanism, behind
it the maze of lead tubing that connects the pipe chests to the
main stack is partially visible. At horizontal center is the electric
motor flat belt drive and crank system that powers the vacuum and
pressure feeders (pumps) at chassis bottom. At the far right is
a pulley countershaft used to obtain a speed reduction for the pump
crankshaft. The small round leather drive belt going to the roll
changer is powered off of the end of the speed reducing countershaft,
and then feeds around an adjustable belt tightener.
