PROVISIONAL SPECIFICATION.
Improvements in Clarionets, Flutes, and the like.
I JAMES CLINTON of 15 Spencer Terrace Earlsfield in the County of Surrey
Musician do hereby declare the nature of this invention to be as follows:-
:-
This my invention relates to improvements in clarionets flutes and the like and
the object of my invention is to so construct the instrument to which my invention
is applied that it may readily and effectively be altered in pitch and tone and may
thus be transposed into another key. For example the clarionet may be changed
from B flat to A or nice rers to suit the key in which the music is written thus
rendering a second instrument unnecessary.
In carrying my invention into effect line the body or shell of the instrument
with suitable tubes preferably of metal the ends of said tubes fitting one within the
other & being so arranged that they may be drawn out to a limited extent.
The said lining tubes are formed with two or more sets of holes for producing
the several notes of the different keys to which the instruments may be tuned.
The outer shell or casing of the instrument may be of any suitable material and
in addition to the usual keys has a number of screws or pins which pass through
the outer casing and engage in slots in the inner lining. The said slots are of a
definite length and are spirally arranged so that the screws engaging in the spiral
slots will allow the tubes to rotate to a limited extent thereby bringing another set
of holes in the lining tube under the operating keys.
One or both of the ends of the instrument are secured to the ends of the lining
tubes and when it is desired to alter the key of the instrument, the ends of the
instrument are partially rotated which cause the before-mentioned screws to
traverse the spiral slots thereby lengthening the instrument and changing the key
the alteration in tone being regulated by the length of the said slots.
The arrangement of the several parts may be slightly varied to suit the
requirements of the various instruments to which my invention is applicable.

COMPLETE SPECIFICATION.
Improvements in Clarionets, Flutes, and the like.
1, JAMES CLINTON of 15 Spencer Terrace, Earlsfield, Surrey, Musician, 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 my invention relates to improvements in clarionets flutes and the like, and
the object of my invention is to so construct the instrument to which my invention
s applied, that it may readily and effectively be altered in pitch and tone and may
thus be transposed into another key. For example a clarionet may be changed
from B flat to A or vice versa to suit the key in which the music is written, thus
rendering a second instrument unnecessary.
In order that my invention may be readily understood reference is made to the
accompanying drawings in which-
Figure 1 shows a clarionet constructed in accordance with my invention a
portion of the shell or casing of the instrument being broken away.

page_text: Figure 2 shows the lining tubes of the instrument with the slots therein as
hereinafter described, and
Figure 3 shows the several joints in the shell of the instrument when drawn out
to their full extent, the keys of the instrument being omitted in this figure.
In carrying my invention into effect I line the body or shell A. of the instrument
with suitable tubes BB preferably of metal, the ends of said tubes fitting or
butting one against the other and being so arranged that they may be drawn out
to a limited extent.
The said lining tube B is formed with two sets of holes for producing the several
notes of the different keys to which the instrument may be changed.
The outer casing or shell A of the instrument may be made in the usual way and
in addition to the usual keys has a number of screws or pins a which pass through
the outer casing A and engage in slots in the lining tubes B & B respectively.
The said slots are of a definite length and are spirally arranged so that the
ends of the screws a engaging in the spiral slots will allow the tubes to rotate
to a limited extent thereby bringing another set of holes in the lining tube B under
the operating keys.
The bell or one end of the casing of the clarionet is secured to the lining tube B
and the other end or socket to the tube B' and when it is desired to alter the pitch
of the instrument the said ends of the instrument are partially rotated in the
direction indicated by the arrows in Figure 1, which causes the before mentioned
screws a to traverse the spiral slots and thereby lengthening the instrument
and changing the key, the alteration in tone being regulated by the length of the
said slots. To prevent any accidental movement of the socket during the playing
of the instrument I form the slot in the tube B of the shape shown in Figure 2,
and upon lengthening the instrument as before described the end of the screw a is
caused to enter that portion of the slot marked which will effectually prevent
any alteration in tone while the instrument is in use.
In order to facilitate the insertion of the screws a when it is desired to connect
the several portions of the instrument together, I attach to the tubes near to the
ends thereof a suitable catch consisting preferably of a stud and a hook d adapted
to engage therewith as shown in Figure 3. When the hook d is in engagement
with the stud c the hole in the casing of the instrument for the insertion of the
screw a will register with the slots in the lining tube, the screws a may be
consequently readily inserted.
As it is necessary that the joint C at the junction of the two main portions of
the instrument shall be of such a nature as to prevent the finger-holes of the said
portions becoming out of alignment, I form the shoulder of the joint with a
feather e or other device which will prevent the independent rotation of either part
but allow the parts of the body to be drawn out as required.
The arrangement of the several parts may be slightly varied to suit the separate
requirements of the various instruments to which my invention is applicable.
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 combination with a clarionet, flute or other similar instrument of lining
tubes for the purpose of transposing the said instrument, the said tubes having
suitable apertures for the production of the several notes and spiral slots formed
therein, the whole arranged and operating substantially as described and illustrated
in the accompanying drawings.
