Look at these
improved features
B
A — Two pivoted tone-control leaves at the mouth
of the amplifying chamber permit modifying the
volume of tone as desired.
B — The cover encloses the scientifically shaped am-
plifying chamber (or horn) which permits the
full and natural development of the sound-waves
(as in the big cabinet Grafonolas) from the neck
of the tone-arm to the mouth of the horn. ^
C — An escutcheon at this point fits over the motor
pinion and secures the turntable against rattle
or damage during transportation.
D — The standard Columbia bayonet-joint tone-arm
conveys the sound-waves directly into the am-
plifying chamber in a continuously widening
channel without obstruction or the necessity of
employing special turns or adjustments to suit
this type of a phonograph.
E — Covers seal needle cups when top is lowered for
carrying.
H
F — Three nickel needle cups (one for used needles)
prevent aggravating forgetfulness.
G — The position of the winding spindle gives the
crank a wide swing, which permits easy and
safe winding of motor.
H— Complete exterior is covered with the best &rade
of heavy black Fabrikoid.
Illustration above shows
how the Portable Grafo-
nola is made ready for
carrying.
/ — Heavy nickeled corner protectors give strength,
withstand abuse, and save scratching of furniture.
J — The inside is finished in highly polished Red
Mahogany, which, with the highly polished
nickel parts and black Fabrikoid exterior, makes
this instrument very attractive in the playing
v
position.
K— Tone-arm and improved standard Columbia re-
producer swing back without adjustment and
are safely positioned by a spring for carrying.

for transportation.
