in the Kingdom of Belgium, Musical Instrument Maker.
I, SAMUEL ARTHUR CHAPPELL of 52 New Bond Street, in the County of
London, Musical Instrument Maker, do hereby declare the nature of this invention
to be as follows:-
This invention relates to clarionets, its object being to facilitate the playing of
passages and trills of E natural and F-sharp or of B natural and C-sharp, or, in
another register of B natural and C-sharp, or of C-sharp and D sharp.
In clarionets as hitherto usually constructed, the F (and C) natural and F-sharp
(and C-sharp) cups have always remained open together, and caused certain notes
of the instrument to be defective and false, and, especially have caused A natural
and E natural to sound dull.
According to this invention the drawbacks above referred to are remedied by a
new construction of No. 1 key and certain other keys hereinafter referred to, it
being understood that in this specification the key referred to as No. 1 key is that
which on an ordinary clarionet gives E natural (and B natural). The other keys
above referred to in connection with the No. I key are the F (and C natural) or
F-sharp (and C-sharp) keys controlled thereby, which are so made that the
F-sharp (and C-sharp) key is normally kept closed, and the F (and C natural)
key open, when the No. 1 key is not operating, whereas the F-sharp (and
C-sharp) key is opened and the F (and C natural) key closed by operating the
No. 1 key.
One construction according to this invention comprises an F (and C natural)
key with a tail overlapping a part of the No. I key, which rises when the latter is
operated, and an F-sharp (and C-sharp) with a tumbler or rocking lever interposed
between it and the said part of the No. 1 key; by this construction, movement of
the No. 1 key causes movement of the F (and C natural) or F-sharp (and C-sharp)
in directions reverse to each other, the several parts being maintained in engage-
ment by the usual springs or otherwise.
The closure of the F-sharp (and C-sharp) key when the F (and C natural) key
opens produces F-sharp (and C-sharp); if whilst either of these two notes are
maintained it is desired to. obtain È natural or B natural, this may be done
according to this invention by a key which carries a cross piece, and can be
operated to depress thereby either the F (and C natural) or the F-sharp (and
C-sharp) key, whichever may be up.

page_text: A communication from JEAN BAPTISTE ALBERT, of 16 Rue du Chalet, Brussels,
in the Kingdom of Belgium, Musical Instrument Maker.
I, SAMUEL ARTHUR CHAPPELL, of 52 New Bond Street, in the County of
London, Musical Instrument Maker, 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 clarionets, its object being to facilitate the playing of
passages and trills of E natural and F-sharp or of B natural and C-sharp or in
another register of B natural and C-sharp or of C-sharp and D-sharp.
In clarionets as hitherto usually constructed the F (and C) natural and F-sharp
and (C-sbarp) cups have always remained open together, and caused certain notes
of the instrument to be defective and false and especially have caused A natural
and E natural to sound dull.
According to this invention the drawbacks above referred to are remedied by a
new construction of No. 1 key and certain other keys hereinafter referred to, it
being understood that in this specification and the claim appended the key referred
to as No. 1 key is that which on an ordinary clarionet gives E natural (and
B natural). The other keys above referred to in connection with the No. 1 key
are the F (and C natural) or F-sharp (and C-sharp) keys controlled thereby,
which are so made that the F-sharp (and C-sharp) key is normally kept closed,
and the F (and C natural) key open, when the No. 1 key is not operating, whereas
the F-sharp (and C-sharp) key is opened and the F (and C natural) key closed by
operating the No. 1 key.
In combination with the foregoing a key such as that which is lettered e on the
accompanying drawings may be employed as and for the purpose hereinafter
explained.
One construction, according to this invention, is illustrated in those drawings
wherein
Fig. 1 is a side elevation of the lower "joint" of a clarionet, and
Figs. 2, 3, 4 and 5 are views of certain of the details of Fig. 1 which are herein-
after particularly referred to; of these latter Fig. 4 is a side elevation, the rest
are plan views.
Like letters indicate like parts throughout the drawings.
This joint comprises an F (and C natural) key a (see Figs. 1 and 2) with a
tail a overlapping the parts of the No. 1 key b which rises when the latter
is operated in the direction indicated by the arrows thereon, the No. 1 key being
in two parts pivotted to the clarionet upon separate pivots at 63 63 and connected
together by connecting devices of a well-known type at ; there is also an
F-sharp (and C-sharp) key c (see Figs. I and 3) with a tumbler or rocking lever d
(Figs. 1 and 4) interposed between it and the said parts of the No. I key; by
this construction, movement of the No. 1 key causes movement of keys a and c in
directions reverse to each other, the several related keys being maintained at all
times in the necessary contact or engagement by the usual concealed springs in the
key spindles or otherwise.
e
.
(Figs. 1 and 5) is a key which carries a cross-piece e¹ the latter being so
disposed relatively to the keys a and b that it can be operated to depress either the
key a or the key c whichever may be up.
?

page_text: The combination of the keys a, b and c in the manner described greatly facilitates
the production of the required trills.
With the key a shut and the key c open the instrument would sound the F-sharp
(and C-sharp); if, whilst either of these two notes is maintained it is desired to
obtain E natural or B natural, the cross-piece e is depressed to close either the
key a or c whichever may be up as before explained.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed I declare that what I claim is :-
1. In a clarionet the combination of No. 1 key and F (C natural), and F-sharp
(C-sharp) keys, arranged and operating substantially as and for the purposes
specified with or without a key such as e.
2. In a clarionet, keys such as a b c, with or without the key e, constructed and
arranged substantially as and for the purposes described and illustrated in the
accompanying drawings.
