Improvements in Wind Musical Instruments.
We, FRANZ OSCAR ADLER, and FÜRCHTEGOTT HERMANN JORDAN, both of
Markneukirchen, Saxony, in the Empire of Germany, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
The invention consists in constructing the body of the instrument of one piece
or tube with a longitudinal curved or sloping diaphragm therein dividing the body,
excepting as to the lower part thereof, into two parts or tubes, to one of which is
fitted the mouth tube and its reed and to the other a flared cup or sound emitting
mouth, said diaphragm descending only to within such a distance of the bottom as
to allow of the full measure of sound passing. At the junction of the mouth tube
with the body a step is formed by the junction of the smaller diameter of the
mouth tube with the larger diameter of the body tube, and the latter tube is
constricted a little by the curvature or slope of the diaphragm about two-thirds
down its length; the bottom of the body is closed by a cover, the arrangements of
the keys is very similar to those of like instruments. The diaphragm is constructed
so as to make the tubes practically one bent tube with an area conically increasing
from the mouth-piece to the sound emitting cup.

COMPLETE SPECIFICATION.
Improvements in Wind Musical Instruments.
We FRANZ OSCAR ADLER and FÜRCHTEGOTT HERMANN JORDAN, both of
Markneukirchen in Saxony in the Empire of Germany, Manufacturers 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:-
The object of this invention is to produce a new or improved musical wind
instrument adapted to be used in replacement of a bassoon, oboe, or clarinet in small
orchestras or in addition thereto in large orchestras, which shall be easily played
by any person who can already play upon a bassoon, oboe or clarinet without much
practice, or by others without any greater difficulties than are experienced in
learning the playing of the aforesaid instruments, and which shall possess a
characteristic tone or sound somewhat resembling that of brass instruments, but
with a capacity of producing octaves in the same manner as in a flute, oboe
or bassoon.
This improved instrument is shown in the annexed drawings in which
Fig. 1 is a longitudinal section thereof,
Fig. 2 a cross section on the line M M Fig. 1,
Figs. 3 and 4 side elevations from different sides.
The invention consists in constructing the body of the instrument of one piece
or tube A closed below at G and having a longitudinal or sloping diaphragm
therein dividing the cavity excepting as to the lower part thereof into two parts
or tubes communicating below so as to constitute one passage way of the form
hereinafter described. At the upper end of the body there is fitted into the one
--

page_text: tube B a tubular extension C of reduced interior diameter D ending above in a
mouth piece, and into the other tube B' a flaring cup H.
At the junction of the mouth tube C with the body A a step E is formed by
the transition from the smaller diameter of the mouth tube to the larger diameter
of the tube B, and the latter tube is conically restricted to about three-fifths of its
length from the top at F whence it is conically widened and this widening extends
upward along the tube 11 to the mouth of the latter. The holes and keys are
arranged as indicated in the drawing and are similar to those of wood wind instru-
ments in general.
The cup H is of metal, the body of the instrument and mouth tube of wood.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A wind instrument having in its body A an out and return air channel B B¹
conically narrowed to F and thence widened to its mouth, in combination with a
mouth tube C of narrower diameter inserted to form a step E substantially as
illustrated and described.
