Modell 12 Monstre Paganini Orchestrion

Philipps six-station automatic music roll changer (revolver mechanik), with wind-motor drive for forward music roll motion.

This six-station Paganini sized Philipps Revolver Mechanic (roll changer) sparkles like new, and holds six music rolls, playing them in rotation one after another, providing a continuation of music before repeating. A round-leather belt drives a system of gears and chains, powering all of the mechanical functions except one; the forward motion of the music roll is powered by a wind-motor, whose speed is carefully regulated and also adjustable to set the music tempo.
New cast iron pulleys on the speed reduction countershaft.

The round-leather belt, part of which is shown at left, powers the heavy-duty needs of the music roll changing mechanism. Central in the photograph is the speed reduction countershaft, fitted with a large and small flat belt pulley used to reduce the rotational speed of the feeder pump crankshaft. At right, a portion of the register switching stack can be seen. In the background part of the 30-note xylophone is visible.
Newly rebuilt piano action for the Paganini orchestrion.

The beautifully restored piano harp and action, the subject of this photograph, can be lifted out of the back side of the Paganini (preferably by two strong men) for servicing and tuning.
