In applying my invention to a cornet or other instrument I. fit on the mouth
pipe or other tube a water chamber in which the moisture collects, in this chamber
I fit a tubular or other shaped valve in which I form an opening or openings which
may be in the upper side to admit the water and an opening or openings, which
may be in the lower side, to allow the water to escape when the valve is moved by
the performer. The holes in the upper part of the valve remain open except
when the valve is moved by the performer to allow the water to escape. The
valve may be formed so as to allow the moisture to escape while the instrument is
being played.
By the use of my invention long solos may be played without inconvenience from
the accumulation of moisture.

MUSICAL INSTRUMENTS,”
"IMPROVEMENTS IN
My invention relates to brass and other wind instruments, my object being to
prevent the accumulation of moisture (caused by the breath of the performer) in
the slides or tubes of the instrument.

page_text: In applying my Invention to a cornet or other instrument I fit on the mouth-
pipe or other tube a case or water chamber in which the moisture collects: in the
upper side of this case or chamber I make an opening or openings communicating
with the instrument to admit moisture and in the lower side I make an opening
for the escape of moisture. In this case I fit a tubular or other shaped valve in
which I form an opening or openings corresponding with the openings in the top
of the case to admit the water and I make an opening or openings in the valve
which correspond with the opening in the lower side of the case when the valve is
moved to allow the water to escape. The holes in the upper part of the valve
remain open except when the valve is moved by the performer to allow the water
to escape. The valve thus formed will allow the moisture to escape while the
instrument is being played.
By the use of my Invention long solos may be played without inconvenience
from the accumulation of moisture.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1. represents a longitudinal section on an enlarged scale of an apparatus
made according to my improvements. Fig. 2 is a section across the middle.
Fig. 3 an end view and Fig. 4 a plan of the same.
a is the outer casing which is secured to the mouth pipe of the cornet or other.
instrument and 66 are the openings to admit moisture which correspond with
similar openings in the valve c: d is the opening in the case a through which the
moisture escapes when the valve c is moved so as to cause the opening e in the
valve to correspond with the opening d. To the valve c is connected a disc ƒ to
which is fixed a projection g which when pressed by the finger turns the valve
partly round, closes the openings 6 b, brings the opening e over the opening d and
allows the moisture to escape. A spring causes the valve to move back when it
is released and closes the lower and opens the upper openings. A small vent hole
is made in the case and one in the valve which admit air when the moisture
escapes through d.
Instead of employing a valve movable in a rotary direction I may use a valve
movable longitudinally or otherwise.
Having stated the nature of my Invention and described the manner of
performing the same I would have it understood that I do not limit myself to
the precise details given as they may be varied or modified without departing from
the main features of my Invention and
I declare that I claim.
The improved apparatus for preventing the accumulation of moisture in the
slides or tubes of musical instruments substantially as herein described and shown.
In witness whereof I the said William Booth have hereunto set my hand
and seal this seventh day of May One thousand eight hundred and eighty
three.
