Improvements relating to the Printing of Music or other matter on
Strips or Bands, and to Apparatus for Exposing the same to the
Reader and for Indicating the Time thereof.
I, CHARLES GERANDAL, of 25, Rue Alfred de Musset, Mustapha, Algeria,
Engineer, do hereby declare the nature of this invention to be as follows.-
This invention relates to the printing of music upon a surface or area propor-
tionate to the time within which the music is to be read. The band whereon the
music is printed is provided with perforations or slots or otherwise made rough or
uneven on one side or within the body of the music, and spaced in such a manner
as to correspond to the various "times" of the music, the said perforations or
the like setting in motion a pawl or lever, adapted to ring a bell; or the pawl may
be simply oscillated in a manner visible to the reader.
.
The music, which is wound upon a wood or metal delivery roller, passes between
two metal cylinders, encased in india rubber, which receive motion from a
clockwork and in their turn set the music in motion, causing it to unwind or
unfold under the reader's eyes; the strip or band on which the music is printed
winding itself upon the upper receiving roller, which is driven by a pulley acting
by slight friction and receiving motion, through the medium of a strap or gear
wheels, from the delivery roller; or from suitable clock work.
The clockwork should be fitted with a starting pawl and an arresting pawl on
one side.
A further pawl adapted to set in operation a spindle carrying toothed wheels
of different diameters, serves to impart different speeds to the rubber covered
cylinders, so that the music may be read more slowly by beginners.
In order to unwind the music, a third pawl, actuating a train of gear-wheels
which transmit the motion to the rubber covered cylinders, may be made to turn
the cylinders in the opposite direction.
"
When it is desired to retard or accelerate one or more bars, instead of moving
away the perforations slots or projections which operate the pawl whereby the
"time
of the music is adjusted, one such perforation, slot or projection, ar-
ranged to act upon the pawls will serve to change the speed of motion of the clock
work. These projections or perforations will also enable the speed of the clock-
work to be varied when either very slow or very quick or lively music is to be
read, as, if the cylinders were constantly moving at one and the same speed,
such music would have to be printed upon either too large or too small a surface.
Instead of music I may print literary matter on strips or bands provided with
slots perforations or unevennesses of the surface.

I, CHARLES GERANDAL, of 12, Rue Ligier, Algiers, Saint Eugene, late of 25,
Rue Alfred de Musset, Mustapha, Algeria, Engineer; do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
The invention which forms the subject of this application relates to the printing
of music on a surface proportional to the time in which the music is to be read.
The invention is illustrated in the accompanying drawing in which :-
Figure 1 is a plan of an arrangement for carrying out my invention and
Figure 2 is a diagrammatic sectional view of the same."
The band or strip L on which the music is printed has holes, grooves or projec-
tions M which are adapted to set in motion a pawl or lever D acting on a bell
or simply causing this pawl to move, the oscillations of which is visible to the eye
of the reader or player.
This music, which is wound upon a wooden or metal roller B passes between
two metal cylinders C covered with india-rubber which cylinders receive motion
from a clockwork Cand in their turn set the music in motion causing it to
unwind before the player, the band or strip rolling upon the upper cylinder A
which is set in motion, by a pulley running with slight friction operated by a
belt or by gear wheels, from the cylinder B, or by a clock movement E.
The speed of the motion of the clock work is calculated so as to cause the
cylinders, and consequently the music, to move during the period in which it
should be read or played, in accordance with the conception of the composers
or artists.
The grooves, holes or projections of the strip of music placed opposite or
in the body of the music cause the pawl 1) to move, the motion of which is
visible or the pawl simply acts upon on a suitable bell to any desired time or
measure.
For measures in which there is an alteration to a slower time the distance
between the holes, grooves or projections will be greater, in such a way that the
player will follow the music in accordance with the time provided for by the
composer.
The clock work has at its side a click or pawl D₁ for starting and one D" for
stopping.
Another click or pawl D" actuating a shaft with tooth wheels of varying
diameters, determines the different speeds of the cylinder C in such a manner
that the music may be moved more slowly for beginners.
To unroll the music, a third click or pawl acting upon toothed wheels which
transmit motion to the cylinders C determines the reverse rotation of the cylinders.
When one or more measures are to be retarded or accelerated, instead of
separating the holes, grooves or projections acting on the click or pawl giving
the measure or the time of the music, a groove, projection or hole Facting on
the pawls G is adapted to change the speed of the clock work.
These same holes or the like determine the change of speed of the clock work,
when it is a question of very slow or very quick music which would, if a single
speed of the cylinders C is adhered to have to be printed upon either too large or
too small a surface.
It is not essential that the music should be printed on a surface exactly pro-

page_text: portional to the time, it is sufficient that the measures do not deviate sensibly
from the holes or projections indicating the time or the measure of the music.
The band or strip of music may only indicate the place where the holes grooves
or projections ought to be made.
Literature may be substituted for music; the notches determining the time
which ought to be kept for good diction, the periods of respiration being indicated
by a hyphen which corresponds to a notch acting on the pawls.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. Printing music on a surface sensibly proportional to the time in which the
music is to be read, and having projections grooves or holes on the side or in the
body of the music, spaced according to the various times or measures of the said
music.
2. An apparatus on which the music above described is moved in either direction
by means of cylinders or any other means actuated by clockwork of regular or
variable speed, the projections grooves or holes of the strip of music, determining
a visible movement or an intermittent sound for each measure or time of the
music, the said grooves, holes or projections being in some cases adapted to change
the speed of rotation of the cylinders.
3. The employment of the above described device for literature printed on bands
or strips having grooves, projections or holes as above described.
