page_text: COMPLETE SPECIFICATION.
I, CARL PIETSCHMANN, a member of the Firm of Ch. F. Pietschmann & Sons,
Musical Instrument Makers, of No. 28 Brunnen Strasse, in the City of Berlin, in
the German Empire do hereby declare the nature of my Invention for "IMPROVE-
MENTS IN MELODIONS, ACCORDIONS, AND OTHER SIMILAR MUSICAL INSTRUMENTS
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 improvements in melodions, accordions and other
similar musical instruments.
The object of this said Invention is to simplify the construction of the present
melodions and other like instruments whereby two vibrator or reed cells are
similtaneously opened by operating one.key only in order to increase the power of
the instrument.
The simplification consists chiefly in connecting the respective valves of the two
rows of reeds or reed cells to one and the same key.
Figure 1 illustrates the said Invention with the valves d d¹ in closed position.
Figure 2 is a like representative showing the valves & d' opened.
Figure 3 is a representation of the spring and lever connection between the key
and the valves.
The keys m are as usual arranged in the keyboard E and turn on the wire o
which is the common fulcrum for all the keys which said keys form two armed
levers to the lower shorter arm of which the wire levers or arms p of the one or
primary row of valves d is rigidly attached whereas the levers or arms p¹ of the
other or secondary row of valves d' are moveably attached to the said lower end of
the said key m.
The valves & which are attached to the outer ends of the wires or wire levers p
are raised by a direct movement by means of the key m whereas the wires or wire
levers p² are provided at their outer ends with a suitable hook f which said hooks
catch into suitable openings e in the valves d' which rest at the one end g against
the ledge or rail L attached to the plate or board D.
On pressing down the key m the valve d' is forced to turn at the foot k of
the ledge or rail L and in this manner the valve to the primary row or set of
[Price Adl

or set of reeds.
It is evident that the hinge like moveable connection of the wire p¹ and the
valve d¹ can be effected in any other appropriate manner without departing from
the tenor of this said Invention.
The valves d d in both rows or series are simultaneously pressed onto their
seats by means of the springs shown in Figure 3 which has a tendency to
continuously press the wire or wire lever p' down and the key m outwards.
These springs 8, id est one spring to each key, are all arranged on the wire r.
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 :-
1-The construction arrangement and employment of the valve mechanism in
melodions accordions and like musical instruments for simultaneously raising two
valves through operating one key by connecting the valve d¹ to the second row or
set of reeds to the key m in such manner that the said valve d' is caused to turn
on the foot point k of the ledge or rail L when the valve d to the first or primary
row or set of reeds is raised by depressing the key m substantially as described
and shown in the accompanying drawing.
2-The general construction and arrangement of the parts in the said
mechanism substantially as described and shown in the accompanying drawing.
