IMPROVE- MENTS IN MUSIC SHEETS FOR MECHANICAL MUSICAL INSTRUMENTS
Year: 1884

page_text: I, PAUL EHRLICH, residing at Gohlis near Leipsic in the kingdom of Saxony,
German Empire do hereby declare the nature of the said invention for "IMPROVE-
MENTS IN MUSIC SHEETS FOR MECHANICAL MUSICAL INSTRUMENTS," to be as
follows:-
The music sheets forming the subject of my invention have the character of
circular sheets, and can therefore be used with instruments similar to those
described in the specification of my British letters patent A.D. 1882 No. 36C0;
but, while with ordinary circular sheets the length of the melody to be produced,
is limited, my improved sheets are adapted to receive perforations for tunes of
any length.
The sheets are composed of a number of divided annular pieces of strong paper,
card-board, or other like material, united with their ends so as to constitute a
continuous surface which, when laid flat, folds together in three or more layers,
whereof at least one is a full circle.
The sheet may be guided in the instrument by conical rolls, the upper ones of
which are so arranged as that the sheet can easily be slipped under thei.

page_text: 1, PAUL EHRLICH, residing at Gohlis near Leipsic, kingdom of Saxony, German
Empire, do hereby declare the nature of my invention for "IMPROVEMENTS IN
MUSIC-SHEETS FOR MECHANICAL MUSICAL INSTRUMENTS," and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
In mechanical musical instruments in which the valves of the reeds are operated
by a perforated circular music-sheet, such as described in the specification of my
British letters patent A.D. 1882, No. 3660, the length of the melody to be produced
by such sheets is limited, inasmuch as the series of perforations corresponding to
the notes or chords of the melody must be contained within the area of a single
circle.
The music-sheets constituting the subject of my present invention have the
character of circular sheets, and can therefore be used with instruments similar to
those described in the said specification, but they are adapted to receive perforations
for tunes of any length.
For this purpose I compose the sheets of a number of annular pieces of strong
paper, card-board. or other like material, divided according to radial lines. or
obliquely, and united with their ends, so as to form a continuous or endless surface,
which, when laid flat, folds together in three or more layers whereof at least one
is a full circle. A sheet of this kind is represented by Fig. 1' of the annexed
drawing in a perspective front view, while Fig. 2 is a perspective diagonal view
of the box of a musical, instrument with the sheet applied thereto, the reeds,
valves and mechanism of the instrument not being shown, as they do not form any
part of the invention. In either figure a portion of the perforations only are
represented.
The sheet a may be guided in the instrument by conical rolls, such as b and c,
and preferably two pairs of rolls are employed. The upper roll or rolls are so
arranged as that the sheet may easily be slipped under them. According to the
drawing they are pivoted with their thin ends in a bearing d hinged to the box f,
while the bearing e for the pivots at the opposite ends is secured to the box by a
thumb-screw, so that both rolls may be turned 'up together with, their bearings.
The part of the sheet which is unsupported by the rolls and the box, hangs at the
side of the latter about in the position shown in Fig. 2.
Having now particularly described and ascertained the nature of the said
invention and the manner in which it is to be performed, I declare that what
I claim is
A music sheet composed of a plurality of divided annular pieces of paper, card-
board or the like, united with their ends so as to form a continuous surface, which
when laid flat, folds together in three or more layers whereof at least one comprises
a full circle, the said surface being provided with perforations corresponding to the
notes to be produced, substantially as and for the purpose herein before described.
