THE MUSIC TRADE REVIEW
APRIL 8,
The Straube Automatic Roll Adjuster
A
MOTHER exclusive feature of the Artronome Player Action.
Note the ball-bearing music roll carrier. Simply insert the roll
and begin pedalling.
The Automatic Adjuster immediately brings the roll into perfect play-
ing position without the slightest attention on the part of the operator.
The perforations of the roll are brought into exact alignment with the
air ducts of the tracker bar—the adjuster is unerring and dependable.
It never needs regulation.
The ball-bearing music roll carriers hold the roll in a positive lateral
and vertical position; in rewinding there is no mutilation of its edges.
And no matter how frayed the edges of an old roll may be the Straube
Adjuster insures perfect playing.
The P a t e n t e d
Pendulum Valve
The Straube transposing tracker bar enables the playing of any roll
in five different keys, simply by depressing a catch-lock and moving the
bar to the desired key.
Its design and con-
struction make this
valve absolutely fric-
tionless and positively
non-corrosive. U s e d
only in the Artronome
Action.
