A NOVEL AND IMPROVED METHOD OF TYPOGRAPHICALLY PRINTING MUSIC
Year: 1886

page_text: I HENRI CHOSSEFOIN, chemist of the city of Paris in the Republic of France do
hereby declare the nature of the said invention for "A NOVEL AND IMPROVED METHOD
OF TYPOGRAPHICALLY PRINTING MUSIC" and in what manner the same is to be per-
formed, to be particularly described and ascertained, in and by the following statement
to be as follows:
--
The object of the invention is to print music, and the various signs and accessories
of which it is composed, by means of type, so obviating the employment of lithography,
or engraving as at present in use, the new mode of printing which forms the subject
of this invention simplifying and expediting printing, with the advantage of simplicity
and economy.
The various notes, half notes, signs, accidentals, sharps, flats rests, the lines, clefs
and so forth are all cast in the usual manner of casting printers type.
The notes, rests and what not that appear in the spaces of the stave, as well as those
above and below it, are shaped on the type as complete notes, but those notes which
appear on the lines are made in parts, that is to say only half such note is represented
on the type, the other or corresponding half being on a separate type. These halves
of notes or other characters are placed one on each side of the line or lines of a stave,
and all rests, clefs, quaver lines, or any signs or notes that come upon the lines of the
stave are similarly constructed; or parts of such signs and so forth made on separate
types. When all these various notes, bar lines, tails to notes, rests, semibreves,
minims &c. &c. of which the piece of music is composed are arranged in the chase,
and quoins inserted for the spacings, the forme is then brought together and locked
by wedges or quoins and is then ready for printing in the usual manner and by the
ordinary means.
Fig. 1 shows the several notes and parts of notes as previously described, seen on
the types.
Fig. 2 shows a stave with clef, notes, rests and so forth, with parts of notes as
herein mentioned, arranged in the chase but not locked together with the quoins, so as
to illustrate the position these notes, and parts of notes occupy before being pressed
together.

page_text: Fig. 3 represents the same stave, notes &c. as they appear when locked in the chase
with quoins, and representing the forme ready to take impressions from.
It will be observed that all those notes and signs &c. composed of two or more paris
when drawn together exactly correspond and form complete characters.
In Fig. 4 the same principle is applied to church music (plain chant) in this
Figure the various notes, signs &c. are represented as unlocked, whereas in Fig. 5
these same notes &c. are shown locked in the chase and ready for printing.
All the notes, parts of notes and so forth are calculated in dimensions to exactly
occupy the spaces, appropriate to them, as before mentioned the parts of notes and
signs &c. when brought together fit so accurately as to appear when printed, as if they
had been impressed from solid and perfect figures or types.
The same remarks apply to all those notes, signs; &c. that appear on the lines or
between the spaces of the stave or the leger lines above or below it.
All these notes &c. can be made or cast in any metal, material, or substance of
sufficient durability.
Having thus described and ascertained the nature of my invention and in what
manner the same is to be performed I claim
The method of printing music with type constructed in the manner herein described,
the different notes, signs, accidentals, rests and so forth where required being made
in parts on separate type, which when locked in the chase ready for printing such
parts unite so as to form complete notes, signs &c. as if they had been so cast on
the type.
The whole in the manner by the means, and for the purpose herein set forth.
