The Pressure Gauge
The Suction Pump
Two Valuable Features
Found Only in
LAUTER-HUMANA
The Pressure Gauge
The Suction Pump
Of great assistance in producing fine
music is the Pressure Gauge, which is
located in the center of the spool box.
This device is connected with the air
reservoir, and accurately measures the
degree of vacuum created by the bel-
lows. The indicator rises and falls as
the volume of air varies and enables the
person who is playing to secure all the
delicate expression effects that mean so
much in good music.
As the music roll passes over the
tracker bar various particles of paper,
dust, etc., are drawn into the small holes
by the suction. Eventually, the valves
become clogged, which prevents the in-
strument from playing properly. The
suction pump—an exclusive Lauter at-
tachment—overcomes this condition. By
placing the mouth of the pump at the
small holes and operating the treadles,
all foreign matter that may be lodged in
the valves or tracker bar is drawn out,
leaving the mechanism clean for efficient
operation. Every owner of the Lauter-
Humana can perform this operation,
which makes unnecessary numerous
trips of the repairman.
We zvill be glad to outline
our plan to dealers who are
interested in a quality product.
