Improvements in Mouth-pieces for Musical Instruments.
A communication from EUGENE ALBERT and JEAN BAPTISTE ALBERT, of
16, Rue du Chalet, Brussels, in the Kingdom of Belgium, Manufacturers
of Musical Instruments.
I, SAMUEL ARThur Chappell of 52 New Bond Street in the County of
Middlesex, 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 mouth-pieces for musical instruments and has for its
object so to construct them with respect to the form of the air passage as to
improve the "attack and render them more reliable in use.
"
The invention will be best understood by reference to the accompanying drawings
in which
Figures 1 and 2 are respectively an elevation and a longitudinal section of one
of our improved mouth-pieces constructed for a clarinet or like instrument, and
Figures 3 and 4 are respectively a plan and a longitudinal section of one of these
improved mouth-pieces for an instrument of the trumpet class such as a cornet.
Instead of forming a mouth-piece for a clarinet or like instrument with a
straight or smooth bore as is usual it is at a convenient part, formed with an
enlargement or chamber as at A.
An instrument provided with a mouthpiece constructed in this manner may be
tuned and played with perfect precision. The immense advantage thus obtained
will be readily appreciated by musicians when it is borne in mind that hitherto with
a straight or smooth bored mouth-piece it has been practically impossible to play
with absolute accuracy at intervals of say twelve entire tones, the twelfth tone
being nearly always too high.
In a cornet or similar mouthpiece the admission end B of the air-passage B' is
of triangular and somewhat tapering form; the remaining portion of the air
passage may be cylindrical or as shown of conical or taper form. This serves to
prevent the air rotating within the mouth-piece and thereby does away with the
fatigue usually attending the production of very high or very low notes on smooth
bored mouth-pieces for this class of instruments. The sound meeting with no
obstacle as it issues, is conducted directly into the tube, and this considerably
diminishes the strain necessitated by its production. Besides as both high and low
notes may be played without appreciable effort, they will not be accompanied by
the disagreeable squeaking sounds which are so frequently observed when ordinary
smooth bored mouth-pieces are employed.
Having now particularly described and ascertained the nature of the said
invention, as communicated to me by my foreign correspondents, and in what
manner the same is to be performed, I declare that what I claim is :-
1. In a mouthpiece for a clarinet or like instrument a passage enlargement or
chamber such as A substantially as described and illustrated in Figures 1 and 2 of
the accompanying drawings.
2. The mouthpiece for a clarinet or like instrument substantially as described
and illustrated in Figures 1 and 2 of the accompanying drawings.
3. A mouthpiece for a cornet or other instrument of the trumpet class having a
triangular termination to the admission end of its air passage substantially as
described and illustrated in Figures 3 and 4 of the accompanying drawings.
