COMPLETE SPECIFICATION.
Typographic Blanks to be Employed for the Impression of Music
and Plain-chant.
I, HENRI CHOSSEFOIN, of 31 Rue Duret, Paris, France, Chemist, do hereby declare.
the nature of this invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention relates to a kind of typographic blank specially formed for the
purpose of being employed in the impression of music and of plain-chant.
The accompanying drawing shows the principal forms which these typographic
blanks may assuine, and also, by the aid of the following description, illustrates their
employment.
It is known that in effecting the typographic impression of music and of plain-chant,
on the one hand blades or plates of thin metal serving to form the lines of each stave
are employed, and, on the other hand, characters are formed as printing characters
usually are, that is to say of cubes surmounted by notes, parts of notes, signs,
accidentals, bars, etc., between which are placed the blanks for filling the spaces which
are to reinain free. These typographic blanks, up to the present, have been those
which are used for ordinary printing, that is to say, cubes of regular horizontal section,
and of a height inferior to that of the cubes bearing the characters, notes, signs and
accidentals. Experience however has shown that this arrangement of typographic
blanks for the special employment under consideration is defective. When the blanks
are of a height slightly inferior to that of the printing characters, they are liable to
get inked in places and to soil the sheets to be printed. If, on the contrary, they are
low enough to avoid all contact with the inking rollers, the metal blades or plates
serving to print the lines of the staves are no longer supported on each side by the
blanks for a sufficient height, and are, by reason of their slightness, liable to become
crushed or at least deformed by the contact of the apparatus serving for the different
operations. Finally, in a general manner, the ordinary arrangement of the blanks in
question is an obstacle to the stereotyping of the compositions, by reason of the
narrowness of the grooves produced by each metal blade or plate in the plastic
material employed for the stereotyping. This narrowness of the said grooves, added
to their depth, resulting from the necessary lowering of the blanks, offers an absolute
opposition to the penetration of the metal infusion, and the stereotyping (clichage) in
this way becomes impossible.
In order to overcome these defects, the typographic blanks in question are, as
shown in the annexed drawing, cut on the top in such a way as to produce on one
hand the necessary hollows, and on the other hand to form kinds of shoulders for
sustaining on each side the inetal blades or plates serving to print the lines of the
staves. These blanks are of two kinds; they are single, as shown in Fig. 1 of the
drawing, in so far as those which are to abut against the exterior side of each outer
line, and they are double or compound, as shown in Fig. 2, for those which are placed
between the lines of each stave. They are cut according to the different arrange-
ments shown in the drawing, or of any other form as desired, that is to say, cut in
an oblique line as in No. 1, or to form a concavity at the summit as in No. 2, or a
convexity as in No. 3, or again they may be cut at right angles as in No. 4, or, finally,

page_text: disposed according to any figure suitable to produce the effects desired. Fig. 3 of
the drawings shows the employment of these typographic blanks in the different forms
described and intimated, in combination with the lines of staves, the blanks a, a, and
the lines of staves or plates b, b, not being shown as completely tightened up one
against the other for the impression, so as to show more clearly their respective
positions.
It will be readily understood that the figures shown arer epresented on an enlarged
scale, and it may further be explained that the blanks in question are systematically
cast so as to be multiples one of the other.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
A kind of typographic blank to be employed in the typographic impression of music
and of plain-chant, such blanks being characterised by the arrangement of their top,
cut according to the different figures represented in the accompanying drawing,
with the object of producing in the complete typographic musical composition for
which they are employed, on the one hand, hollows of certain forms, and on the
other hand, shoulders for the efficient support of the lines of the musical staves, such
arrangement being for the object and to produce the effects hereinbefore described,
all substantially as specified, and as shown as an example in the accompanying :
drawing.
