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. |
