I JAMES BANNEHR of 179 Aldersgate Street in the City of London Inventor do
hereby declare the nature of my invention for AN IMPROVEMENT IN DOMESTIC
UTENSILS TO ENABLE THEM TO INDICATE WHEN THEIR LIQUID CONTENTS ARE
BOILING to be as follows:-
The object of this invention is to indicate in domestic utensils when water is at,
or above, the boiling point-To accomplish this I place in the top, cover, lid or
other suitable position in such domestic utensils, a fitting, consisting of a sensitive
Bounding apparatus, such as a whistle or similar contrivance, whereby the steam,
consequent on boiling water, passing into and through such apparatus, may indicate,
by the sound caused thereby, that the water is in a boiling state-Such indicator
may, if desired, be made to fit and serve as a handle in the lid or cover of such
domestic utensils, which lid or cover may be surrounded by a soft cotton, or other
suitable cord, the ends of which may be drawn through a hole to the inside of such
lid or cover, so as to check the escape of steam in that direction. When such
domestic utensils have a spout the inlet to which is above the water level such
indicator may be placed as a temporary plug in the outlet of such spout.

I JAMES BANNEHR of 179 Aldersgate Street in the City of London, Inventor 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 indicate in domestic utensils when the water
or liquid therein is at or above the boiling point. To accomplish this I place in
the top, cover, lid or other suitable position in such domestic utensils a fitting
consisting of a sensitive sounding apparatus such as a whistle or similar contrivance
whereby the steam by passing into and through such apparatus may indicate by
the sound caused thereby that the water or liquid is in a boiling state. Such indi-
cator may if desired be fitted so as to serve as a handle to the lid or cover of such
domestic utensils and the lid or cover may be surrounded by a soft cotton or other
suitable cord the ends of which may be drawn through a hole to the inside of such
lid or cover so as to check or prevent the escape of steam around the lid.

Figure 1 of the annexed drawings is a side elevation and Figure 2 a section on
the line 1 1 of Figure 1 of a saucepan lid with a whistle fitted in the top
thereof in accordance with my invention, the whistle also serving as the lid handle.
a is the lid and b the whistle which is soldered or otherwise fixed in an aperture
'formed for the purpose in the centre of the lid. The top of the whistle is shown
as closed by a knob c but any other device such as a flat piece of metal will answer
the purpose. The knob is preferably made hollow so as to give a deeper sound to
the whistle.
Figure 3 shows my invention applied to a saucepan lid which has a loop handle d.
In this case the top of the whistle b can be conveniently closed by soldering or
fixing it to the under side of the handle.
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
I claim is
Fitting to the top, cover, lid or other suitable part of domestic utensils sub-
stantially as described a whistle or other sensitive apparatus which when the liquid
contents of the utensil are boiling will be caused to sound by the passage through
it of the steam from the boiling water or liquid as and for the purpose set forth.
