PATENTS MUSIC SHEET TRACKER
Details of Patent Granted to John T. Rydberg
Bearing Upon the Proper Relation Between
Traveling Note Sheet and Tracker
WASHINGTON, D. C, May 31.—John T. Rydberg,
Harrisburg, Pa. (now a resident of Brooklyn),
was recently granted Patent No. 1,373,100 for
devices commercially known as automatic music
sheet trackers, designed for co-operation with
automatic player-pianos by means of which the
proper relation between the traveling note sheet
and the tracker is maintained.
In this character of mechanism there are sev-
eral considerations which become important in
order to produce a practical arrangement,
among which may be mentioned simplicity and
stability of structure to prevent likelihood of
the device getting out of order and requiring
expert mechanics to repair; elimination of valve
complications; adaptability to conventional types
of player instruments; positiveness and quick-
ness of the control means; 'and last, but not
least, the provision for operation without fail
regardless of the condition of the note sheet as
to irregularities of the edges or other portions
due to wear and tear and atmospheric changes.
With these phases in mind the patentee con-
ceived the invention of this application, which
is simply designed for attachment to well-known
players without material alteration in their con-
struction, and possessing the several features of
advantage above referred to, as well as others.
The invention consists of a pneumatic embody-

ing a movable member which under normal con-
ditions of operation of the traveling note sheet
is effected by balancing pressure or "tension"
at opposite sides and controlled through the in-
strumentality of operative connection with sup-
plemental apertures in the tracker or tracker
bar, said apertures immediately becoming opera-
tive upon abnormal movement of the note sheet
effecting a relative movement of the parts to
thereby normalize feeding of said sheet onto
the take-up roll.
Special features of the invention include the
provision of suitable conduits on the tracker bar
into which the supplemental apertures aforesaid
open and means for equalizing the lateral pres-
sure on the music roll whereby the pneumatic
may be normally free of outside pressure so as
to be quickly responsive to shift the roll sup-
port for effecting relative movement of the note
sheet with respect to the tracker bar.
Of considerable importance is, firstly, the com-
bination with the pneumatic of means for con-
trolling its action so that its movements in the
normalizing of the travel of the music note sheet
will be accomplished quickly and positively, but
with a decided absence of objectionable jerki-
ness, this being the function of what is termed
neutralizing or pressure-checking valves form-
ing a part of the invention; and, secondly, the
special connection intermediate, the movable
clement of the pneumatic and the shiftable music
spool such that a minimum amount of pressure
or power is required to produce the desired
movement of said spool.
Subsidiary to the foregoing, but of equal im-
portance, is the combination with the tracking
control means above referred to of means for
rendering said control means inoperative, which
said means is operable incident to the rewinding
of the note sheet upon the music spool so that
such rewinding will be accomplished smoothly
and without tearing the edges of the sheet.

TO DISCUSS WORLD TRADE PROBLEM
Americans to Be Prominently Represented at
International Chamber of Commerce, to Be
Held in London Late This Month
Some 200 delegates from all sections of the
United States will attend the first conference of
the International Chamber of Commerce, to be
held in London, England, during the week of
June 27, and a number of prominent bankers and
financiers will present reports and submit recom-
mendations regarding business conditions of the
world. Transportation and finance will be the
chief subject of discussion, but the question of
production will also find a place on the program.
IBANEZ COMMENTS ON MUSIC
Declares That It Is the Invention of Our Age
and Explains Why
In a recent magazine article on "The
Future of a Novel," by Belasco Ibanez, the fol-
lowing reference was made to modern music
which is worthy of thought: "The novel is an
original creation of modern literature. When
historians ot the future ask what we, the in-
tellectual offspring of the eighteenth, nineteenth
and twentieth centuries, have contributed to the
development of art, we may answer proudly:
music and the novel. No one will venture to
question that claim.
"Music is an invention of our age. Of course,
there has always-been music; but real music, the
art of producing psychological effects by sound,
belongs to our epoch and is one of our great
achievements. For hardly more than a century
and a quarter has profane 'popular' music been
clearly distinguishable from religious ceremony,
and in that brief period of time it has attained
an eminence and excellence which really seem
insuperable."
