COMPLETE SPECIFICATION.
Improvements in or relating to the Keys of Accordeons and the like.
We, CARL WILHELM MEINEL, Senior, and CARL WILHELM MEINEL, Junior,
Manufacturers, of the Firm of C. W. Meinel, of Klingenthal, Saxony, in the Empire
of Germany, 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 folowing statement:-
This invention relates to an improved arrangement of the keys in accordeons,
and similar musical instruments.
Hitherto it has been difficult to remove a key from its position.
It was necessary to unscrew the handle, or to pull the bearing wire out, in which
latter case all the keys were brought out of connection with the cover and could be
brought again into the right position only with much trouble and loss of time.
In this new construction the said inconveniences are completely avoided, and
each single key can be taken out and easily inserted again independently from the
others.
The arrangement for this purpose is the following:-
In the annexed drawing
Fig. 1 shows a
key taken out of the cover.
Fig. 2 is à front view of the key.
Fig. 3 shows a cover with keys partly guided in a special bridge, partly repre-
Bented lying free.
Fig. 4 shows a key when seated.
Fig. 5 shows a key with the front guided in a special bridge.
Fig. 6 shows the arrangement in which there is a double range of keys one at
each side of the handle.
The keys T are each provided with a recess i, in which the bearing wire g is
placed.
Over the back of the key there is arranged the spring 6 which is fixed in a suit-
able manner and holds the key in place.
The key is also provided with a suitably formed trigger d.
In order to take the key out, it is only necessary to lift the spring 6 and to press
the key upwards, so that the recess i leaves the bearing wire g, when the key is
free, and can be removed.
When the key is to have a special guiding, the guiding bridges (Figs. 3 and 5)
can be fitted, in which the ends of the keys have their bearing.
In the grouping of the keys on both sides of the handle, as shown in Fig. 6,
there is arranged a special driving-piece with trigger e for moving the back
key h, so that the triggers of the front and back keys lie side by side on the front.
side, and the separate front and back keys can be taken out easily, and without
hindrance.
The chief point of novelty lies in the peculiar bearing and fastening of the
separate keys, so that each of them without influencing the others, can be taken
out and the corresponding reed or equivalent sounder be uncovered.

page_text: The arrangement, formation, and grouping of the keys can be carried out in
various ways.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed we declare that what we
claim is :-
1. An improved accordeon or the like in which the levers T, having a recess i,
are seated on a rod 9 and are pressed down by springs fixed on the cover a of
the key board, for the purpose of enabling the valve levers to be easily taken out
singly.
2. A form of construction of the accordeon or the like as in Claim 1 in which
between the lever T on the key side of the key-board there are arranged levers f
with triggers e by which there are operated levers h on the under or rear side of
the key board.
