Musical Instrument for Children.
I. GEORG FISCHER of Hinterm Bahnhof, Nuremberg, in the Kingdom of
Bavaria, German Empire, Manufacturer. 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 an improved musical instrument, in which the bellows
as well as the tongue plate are moved at the same time by means of a new and
simplified device, which, in spite of its great simplicity, operates the parts named
above in perfectly reliable manner.
In order to make my invention more clear, I refer to the drawings sent in, with
Provisional Specifications, in which drawings:
Fig. 1 is an upper view of the new musical instrument,
Fig. 2 is a side-view of the same,
Fig. 3 is an upper view of the bellows,
Fig. 4 is a vertical section through the instrument,
Fig. 5 is a rear view of the same, and
Fig. 6 shows a detail.
The bellows a fixed to the main-plate b has an aperture e corresponding with an
aperture d in the main-plate. A felt-plate e also having a corresponding aperture
is attached to the upper side of main-plate b, this latter having a pin or screw f
for holding the tongue-plate y with its tongues h. Tongue-plate g is slightly pressed
an felt-plate by a spiral-spring i.
An axle slightly cranked at 1 has a larger crank m for turning it; the bearing
of said axle being between main-plate 6 and the upper plate of bellows a. A short
vertical connecting-rod n is attached at one side to the little crank and at the
other to a pin o secured to the under plate of bellows a. The point of rod nis
elongated above crank so as to act on the teeth or projections at the rim of the
tongue-plate g.
Now, when holding the main-plate & with the hand, and turning crank m in the
direction indicated by arrow p in Fig. 5, the bellows a will be alternately expanded
and contracted, so as to suck air through the holes e d, and expel that air afterwards
through the same holes.,
During the time of operating the bellows, tongue-plate gis by the influence of the
top of rod n on the teeth or projections intermittingly rotated, thus placing the
tongues one after the other over aperture d.
Plate y remains motionless during every-sucking period, and the air sucked into
the bellows enters the latter through the respective tongue-hole over aperture d,
thus causing vibrations and tones of the respective tongue. The air is entirely
prevented from entering the bellows between the plates g and h, as the pressure of
the atmosphere effects perfect tiglitening during every sucking-period.
When moving crank and with it rod n upwards and forwards again by means of
crank m, the air contained in bellows a is forced out through the openings cd,
whilst plate g is moved at the same time by the top of rod n.
No tone is produced now, there:being neither a tongue above the holes cd nor any
atmospheric pressure on plate g.
The tongues on plate are chosen so as to play any melody, which may be played

page_text: by simply turning crank m, by means of which the necessary movements are
imparted to the bellows as well as to the tongue-plate in the manner above
described.
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
In a musical instrument with tongue-plate and bellows: The combination of
tongue-plate g having teeth or projections r, and of axle k having main-crank m
and supplemental crank 1, with connecting-rod n having its one end secured to
bellows a, and moving the tongue-plate intermittingly by its other end; said other
end being elongated above crank 1, the latter operating rod n in the manner
described.
