PROVISIONAL SPECIFICATION.
Improvements in the Construction of Flutes, Flageolets, and similar
Wind Instruments.
I, RICHARD WALSINGHAM WESTERN, of Perry Mead, Bath, in the County of
Somerset, Civil Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct flutes, flageolets and similar wind
instruments so that they may be played in two or more distinct scales, or may be
altered in pitch continuously from one scale to another as desired, the semitones being
obtained in the usual manner.
According to this invention, I construct the flute or similar wind instrument of the
ordinary cylindrical shape provided with the requisite number of apertures or openings
to produce the various notes. I also provide an outer tube which fits over the cylinder,
the two being attached by means of a bayonet joint, the cover being furnished with a
longitudinal slot or slots or openings which coincide with different sets of apertures
in the cylinder according to the position of the pin in the slot of the bayonet
joint, by means of which the effective length of the sounding tube may be also
regulated.
If desired, the inner tube may be provided with the longitudinal slot, and the outer
tube provided with the apertures or openings to produce the various notes.
Dated this 1st day of August 1889.

Improvements in the Construction of Flutes, Flageolets, and similar
Wind Instruments.
I RICHARD WALSINGHAM WESTERN Perry Mead Bath Somerset Civil Engineer
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 construct flutes, flageolets and similar wind
instruments so that they may be played in two or more distinct scales or may be
altered in pitch continuously from one scale to another as desired, the semitone being
obtained in the usual manner.
For example I provide an ordinary playing whistle and in addition to the six holes
or notes therein cut, I cut a similar number of holes in a longitudinal direction around
the diameter of the tube of the whistle, the outlet end of which is so constructed that
an adjustable sliding tube which is passed on to same increases or decreases the
length of the tube of the whistle (acoustically) when shifted to suit the various sets of
holes.
At the upper end or towards the mouth piece end of the tube of the whistle
a suitable stop or pin is provided for the purpose of engaging with corresponding
notches in the said top of the adjustable tube.
The inside of the adjustable tube is lined with a suitable material to ensure an air
tight connection between the whistle and the sliding tube.
In the annexed drawings
Fig. 1. shews view of whistle containing the said sets of holes.

in the whistle, when it is required to alter the key note.
Fig. 3 shows view of whistle showing the adjustable sliding tube in position and
exposing the set of holes through slot b. a whistle containing 4 sets of holes, 1, 2, 3
& 4. slit in adjustable tube c. d stop on whistle a.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The invention substantially as described and set forth in the annexed drawing
consisting of a whistle containing a set of holes in combination with a sliding or
adjustable tube having a slot or its equivalent substantially as described herein and
for the purpose as set forth.
2. In the herein described invention the employment of an outer sliding tube or its
equivalent, containing a slot constructed and arranged substantially as described and
for the purpose set forth.
