Autophone Reed Frame with Wood Air Channel
By Charles Moore

I was recently sent a 22-note Autophone for restoration and was
surprised to find that the design was a little different.  The 22-note
Autophone is a small handheld instrument with a pressure bellows that
you squeeze to both produce the air and advance the music strip.
I have seen maybe 10 or 15 over the years but none like this one.

The reeds are very small and are mounted on a single brass harp.  On
a typical Autophone there is a brass channel piece soldered on the harp
that directs air up through each reed to the tracker bar.  On this unit
the channel piece is machined out of wood and is (was) glued to the
back of the harp.  The wooden piece is very delicate and would have
been difficult to machine.

The ratchet arms that drive the music strip are also different.  On
a typical Autophone the arms are formed (bent) from thin brass but on
this one the arms are machined out of thicker stock.  The configuration
of the timing slot lever and spring is also completely different.
Pictures comparing components of the this instrument and a typical
Autophone can be found at  http://www.honorrolls.com/autophone.htm

I suspect this is an early design but Autophones were not dated, as far
as I know.  I would love to hear back from anyone that has seen or has
information on an Autophone like this one.

Thanks,
Charlie Moore
P.S.  Thanks MMD!
