Interior Views of the Philipps Pianella
Modell 14 Paganini Geigen Orchestrion
(Photographs circa 1993-1994, marking the
beginning of a Restoration Project) |

The interior of the Paganini orchestrion,
with the pipework in the Melodie Violin pipe chamber removed.
The layout of components in the lower half follows the same
general pattern as its predecessor, the Pianella Cäecilia
(Wurlitzer Concert PianOrchestra). The upper half is reversed,
with trapwork on the left side, instead of the right. |

The top half of the orchestrion contains
all of the musical voices and trapwork effects, with the
exception of the piano and orchestra bells, which are in the
bottom half. One technical exception is the harmonium, which is
not "in" the upper half, but which hangs on the outside of the
back panel, near the top of the casework. |

The trapwork (percussive effects) located
in the upper left side of the machine. The bass drum (blue
shell), with its kettle drum effect, is at top right. To its
left is the tambourine, and to its left and down a bit is the
cymbal (difficult to distinguish). At lower center is the snare
drum, an to its left and down is visible the characteristic
black outline of the castanets, with its pneumatic action
obscured behind the trapwork control valve chest. The triangle
is located sideways between the bass and snare drums. |

The Melodie Violin pipe chest and its
pipework are contained within a swell chamber, with carefully
controlled swell shutters to provide for lifelike volume
expression. The pipe chest accommodates eight ranks of pipes,
which were removed for this picture documenting the chest
preceding dismantling and restoration of the machine. |

The back side of the Paganini orchestrion,
showing the rear-most rank of bass Violoncello pipes. There are
three ranks of pipes in the bass and accompaniment section. This
pipework does not have its own swell chamber, as does the
Melodie Violin section, but is afforded expression, nonetheless,
by the swell shutters located in the top roof panel of the
orchestrion. |

The harmonium (which provides a pleasant
reed organ type of sound and tone) hangs outside the main
casework on its backside and near the top of the orchestrion.
Clearly, this piece of clumsy equipment hanging on the backside
prevents pushing the big orchestrion up close to a wall, but
such wide clearance does have the advantage of making the piano
more clearly audible. |

This view from the rear, with the piano
harp removed, shows the backside of the main (pneumatic) stack.
The three rows of small pneumatic motors lift push-rods that
contact and cause the corresponding piano notes to sound.
Underneath the main stack is the wind-pressure reservoir, with
its heavy duty leaf springs that provide a constant force on the
top of the inflatable reservoir. |

The roll changer (revolver mechanik) is at
left. The black colored wind-motor that drives the music take-up
spool is at center right. The four pneumatic motors on its
backside are timed by the two slider valves on the front side,
causing the little crankshaft to spin. The 18-note orchestra
bell unit is above and to the left of the wind-motor. The main
stack is partly visible in the background. |

The roll changer is powered by the round
leather belt idling upwards from the bottom of the picture. This
revolver does not have the typical friction-disk type music
tempo speed control. Instead, the music take-up spool is driven
forward by a variable speed wind-motor, which is engaged and
operational whenever there is a vacuum applied to the
orchestrion's control system. |

The 18-note orchestra bell unit is at the
top. Below it is the flat-belt speed reduction countershaft
situated between the electric motor and crankshaft, which, in
turn, operates the feeder bellows. |

The electric motor and downstream flat-belt
driven power train culminate with the wind-pressure and vacuum
feeder pumps in the bottom of the machine. These feeders (pumps)
supply the pneumatic energy used to activate all musical effects
and voices throughout the entire instrument. Each of the upper
tier wind-pressure bellows and the lower vacuum bellows are
mechanically linked together by a securely attached bearing and
yoke assembly, which is fixed at the end of each connecting rod. |

The (gray) electric motor that powers the
orchestrion is at left. It is connected by a flat belt to the
speed reducing countershaft on the other side of the machine. On
the countershaft, a small pulley for round leather belting
powers the roll changer, and a flat belt from another small
diameter pulley runs back across the machine to the crankshaft,
which is adjacent to the electric motor. |
