I COLLARD AUGUSTUS DRAKE, of 3 Bedford Square, in the County of Middlesex,
Manufacturer, do hereby declare the nature of my invention for "IMPROVEMENTS
IN THE MANUFACTURE OF THE MECHANISM OF FLUTES, CLARIONETS AND OTHER
LIKE KEYED INSTRUMENTS to be as follows:-
"
The object of my invention is to reduce the cost of manufacturing the mechanism
of flutes, clarionets and other like keyed instruments such, for example, as oboes
and bassoons.
Hitherto it has been usual to make the keys either with the cup, shank and tail
all in one piece, or with the cup of a separate piece and the shank and tail in one
piece, the shank and cap being subsequently soldered together. The shank in both
cases has been filed to the usual shape and has had a hole drilled in it to enable it
to be slipped on to the usual tube and it has been fixed in the proper position on
the tube by solder run in at the ends of the hole. All superfluous solder has had
to be removed by a file or other means. The finger-presses have been made and
fixed in a similar manner.
Now, according to my invention, I turn the sbank with a ball, sphere or other
suitably shaped boss at its rear end and I then drill a hole through the ball to
enable it to be slipped on to the tube. If the key requires a tail in line with, or .
forming a prolongation of, the shank, I either form this tail, by turning, at the
same time as the shank and ball or I screw it into the ball; if the key requires a
tail at right angles, or any other angle, with the shank I screw it into the ball.
I flatten, or reduce, the front end of the shank to the thickness of the cup to which
I then solder it. In order to fix the shank on the tube I form a hole through the
side of the ball this hole extending into the tube hole and when the shank is in its
proper position I insert solder through the side hole, this solder firmly unites the
shank to the tube and, with ordinary care, there will be no superfluous material to
be subsequently removed as in the ordinary way of soldering the shank to the
tube. The key is now ready for the polishing lathe.

page_text: If desired the ball or boss may be made separately from the shank but I do not
recommend this because it necessitates the subsequent soldering of the shank to
the ball or boss. When they are thus made separately the boss may consist of a
short piece of tube which fits upon the usual tube and in this case the boss or short
tube should be bored with a hole to receive the rear end of the shank after which
the parts are soldered together.
Although I have described my invention as applied to the keys it is also
applicable to other parts of the mechanism which have to be fixed to the tubes
such, for example, as the finger-presses.

I, COLLARD AUGustus Drake of 3 Bedford Square in the County of Middlesex,
Manufacturer 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 my invention is to reduce the cost of manufacturing the mechanism
of flutes, clarionets, and other like keyed instruments, such for example, as oboes
and bassoons.
Hitherto it has been usual to make the keys either with the cup, shank and tail
all in one piece, or with the cup of a separate piece and the shank and tail in one
piece, the shank and cup being subsequently soldered together. The shank in both
cases has been filed to the usual shape and has had a hole drilled in it to enable it
to be slipped on to the usual tube and it has been fixed in the proper position on
the tube by solder run in at the ends of the hole. All superfluous solder has had
to be removed by a file or other means. The finger-presses have been made and
fixed in a similar manner.
Now according to my invention I turn the shank with a ball, sphere or other
suitably shaped boss at its rear end and I then drill a hole through the ball to
enable it to be slipped on to the tube. If the key requires a tail in line with or
forming a prolongation of the shank, I either form this tail by turning, at the same.
time as the shank and ball, or I screw it into the ball; if the key requires a tail at
right angles, or any other angle, with the shank I screw it into the ball. I flatten
or reduce the front end of the shank to the thickness of the cup to which I then
solder it. In order to fix the shank on the tube I form a hole through the side of
the ball, this hole extending into the tube hole and when the shank is in its proper
position I insert solder through this side hole; the solder firmly unites the shank
to the tube and with ordinary care there would be no superfluous solder to be
subsequently removed as in the ordinary way of soldering the shank to the tube.
The key is now ready for the polishing lathe.
If desired the ball or boss may be made separately from the shank but I do not
recommend this because it necessitates the subsequent soldering of the shank to
the ball or boss. When they are thus made separately the boss may consist of a
short piece of tube which fits upon the usual tube and in this case the boss or short
tube should be bored with a hole to receive the rear end of the shank after which
the parts are soldered together.
Although I have described my invention as applied to the keys, it is also
applicable to other parts of the mechanism which have to be fixed to the tubes
such, for example, as the finger presses.

The annexed drawings illustrate my invention. Figure 1 is a side view and
Figure 2 a longitudinal section of a turned metal piece consisting of a shank a and
a ball or sphere 6 but without a part for forming the tail. Figure 3 is a longi-
tudinal section of the same metal piece after a hole c has been drilled through it to

page_text: enable it to be slipped on to the usual tube and after it has been reduced or filed
down on its upper and under sides as herein before described to the thickness of the
cup for which it is intended. Figure 4 is a side elevation and Figure 5 a plan
showing the piece a b soldered to the cup d. When the key requires a tail piece
in line with the shank a as seen at e Figure 6, this tail piece may either be turned
with the piece a b. Figures 1 and 2, or it may be formed separately and screwed
into the ball b; if the key requires a tail piece at an angle with the shank a, as
seen for example at f Figure 7, I form this piece separately and screw it into the
ball. In order to fix the shank a on the tube I form a hole through the side of
the ball bas seen at g Figure 3, this hole extending into the hole c and when the
shank is in proper position on the tube I insert solder through the hole g; this
solder firmly unites the ball of the shank to the tube. The key is now ready for
the polishing lathe. Figure 8 is a horizontal section showing the key in place, his
the tube to which the shank is fixed and i is the ordinary wire upon which the
tube is fitted.
Figure 9 represents a way in which a finger press can be manufactured according
to my invention. b is a ball or boss turned with a projection or pin k; the 'ball is
drilled as before described with a hole to enable it to be slipped upon the tube h
to which it is fixed by solder inserted through a hole such as g, Figure 3. The
shank a of the finger press is a wire or rod with the outer end flattened to form
the press proper d. The inner end of the shank is drilled to, receive the
projection of the ball b and the parts are fixed together by means of solder.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
claim in respect of the manufacture of those parts of the mechanism which have
to be fixed to tubes of flutes, clarionets and other like keyed instruments is
1. The manufacture of the shanks by turning the same with a ball or other boss
at its rear end and with or without a tail, drilling a hole for the tube in such ball
or boss and flattening or reducing the front end of the shank to the thickness of
the cup or part that has to be united to it, substantially as set forth.
2. The fixing of the ball or boss (whether turned in a piece with the shank or
made separately and afterwards fixed thereto) to the usual tube by forming a hole
in the side of such ball or boss and inserting solder through this hole, substantially
as set forth.

3. The manufacture of the mechanism of flutes, clarionets and other like keyed
instruments, substantially as set forth.
