Improvements in mechanical musicalments.
I, FRIEDRICH ERNST PAUL EHRLICH, manufacturer of musical instruments, residing
at Gohlis near Leipsic in the Kingdom of Saxony, do hereby declare the nature of
this Invention to be as follows:-
My invention relates to mechanical musical instruments in which the note-
producing parts are caused to operate in accordance with the perforations or recesses
of music-sheets, or their known equivalents, through the medium of levers having
beaks capable of engaging with the said perforations or recesses, and it consists in
the combination, with the music-sheets and levers, of strings and reeds sounded
respectively by means of hammers and by currents of air, and moreover in the
combination, with reeds operated as described, of bellows adapted to produce a
suction-current through the same.
For this purpose each of the aforsaid levers is so connected to the corresponding
hammer and the valve of the reed that, when the lever drops into a hole or recess of the
music-sheet, the hammer will be impelled by a spring or otherwise against the string,
and the valve of the reed will be opened, whereas when the lever is depressed by a
full or projecting part of the sheet, the hammer will be fully returned to its position
of rest and the valve reclosed. In order that the valve may be pressed close against
its seat, a spring is interposed between the aforesaid lever and the valve-lever.
For causing the bellows to produce a suction current through the reeds, the valve
between the reed-box and the bellows is arranged to open inwardly in respect to the
latter, while the outer valve of the bellows opens outwardly. Moreover the
regulating-bellows is provided with a spring tending to expand the same.

Improvements in Mechanical Musical Instruments.
I, FRIEDRICH ERNST PAUL EHRLICH, manufacturer of musical instruments, residing
at Gohlis near Leipsic, in the Kingdom of Saxony, 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 :-
My invention relates to mechanical musical instruments in which the note-
producing parts are caused to operate in accordance with the perforations or recesses
of music-sheets, or their known equivalents, through the medium of levers having
beaks capable of engaging with the said perforations or recesses, and it consists in
the combination with the music-sheets and levers, of strings and reeds sounded
respectively by means of hammers and by currents of air, and moreover in the
combination, with reeds operated as stated, of bellows adapted to produce a suction-
current through the same.
On the annexed sheet of drawings the main part of an instrument involving my
improvements is shown by Fig. 1 in sectional elevation. Fig. 2 is a portion of a
section thereof on line 1, 2.
l
In Fig. 1e is the note-sheet and a one of the levers having a beak formed to be
capable of engaging with the perforations of the sheet e the said lever being pressed
upward against the latter by a spring d. is the string to be operated by the haimmer h
actuated by the spring i, and b, b, & are the valves of three reeds c superposed in
oblique lines, as shown by Fig. 2. The levers 6' of the valves bare provided with
springs tending to open the valves. Each lever a is so connected to the corre-
sponding hammer by a rod fand to the valve-lever by a rod y that, when the lever a
is pressed down by a full part of the note-sheet, the hammer is kept in its position of
rest, and the valve closed. Upon the beak of the lever a dropping into a hole of the
niusic-sheet, the hammer will be released and impelled by the spring i against the
string 1, while the valve of the reed is opened by the spring & belonging thereto.
By the following full part of the sheet the hammer is depressed again and the valve
reclosed. In order that the valve may be pressed close against its seat, the rod
bears against a spring m fixed to the lever b.
For causing the bellows n to produce a suction-current through the reeds, the
valve p, controlling the communication between the reed-box s and the bellows, is
arranged to open inwardly in respect to the latter, while the valve q opens outwardly.
Moreover the regulating bellows o are provided with a spring tending to expand
the same.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :
1. The combination, with a music-sheet, e, having perforations or recesses, a lever, a
having a beak capable of engaging with the said perforations or recesses, and a
spring, d, of a string, l, a hammer, ½, a reed, c, and a valve, b, and means whereby
the hammer is operated to strike against the string, and the valve b is opened when
the lever a drops with its beak into a perforation or recess of the sheet e, substantially
as and for the purpose described.
2. The combination, with a music-sheet, e, having perforations or recesses, a lever, a,
having a beak capable of engaging with the said perforations, or recesses, and a
spring, d, of a string 1, hammer h, spring i, rod f connecting the lever a with the
hammer, reed c, valve attached to the lever 1, spring, k and rod g extending from
the lever a to the lever b¹, substantially as and for the purpose specified.
3. The combination, with the reed-box s, of the bellows n having the valve p opening
from the reed-box towards the bellows, and the valve 9 opening from the bellows
outwardly, substantially as and for the purpose set forth.
