In the 07.05.05 MMD I asked about the machine shown in the
Weiss-Stauffacher video on YouTube, which it turns out was posted by
Björn Isebaert. Nelson Barden told me everything I wanted to know.
The machine is a manual roll puncher from the Welte factory. It was
fairly recently sold to the Seewen, Switzerland, automatic musical
instrument museum from the Milhous collection in Florida.
The Seewen museum has a large Welte organ that they are restoring,
and to go along with it Herr Weiss-Stauffacher bought the Welte roll
duplicator as well as the manual punching machine that was the subject
of my interest. As I may have said, my interest was piqued by owning
a picture of the arranging room of the North Tonawanda Musical
Instrument Works (NTMIW) from back in the days when they were, as the
picture shows, still working with pinned barrels. In that picture is
a machine much like the Welte machine shown in the Weiss-Stauffacher
The manual punching machine works like this. The semi-circular arc
at the back of the machine is marked with the various required notes
of the organ scale being punched. A pointer can be moved to pick the
note to be punched into the paper running on the bed of the machine.
The punching is done by a one-punch die travelling on a horizontal
beam. A system of gears and pivots linking the pointer to the punch
die moves the punch die to the position over the paper that corresponds
to the note written on the semi-circular arc to which the pointer
In other words, the machine is a fancified Leabarjan. Judging from
the Welte example and the NTMIW example, the machine must have been
a fairly common one in arranging departments in the old days.
