page_text: We, HENRY ALBERT GALLIERS and FREDERICK KLAERR both of Inkerman
Street, St. Kilda, in the Colony of Victoria, Plumbers and Gasfitters, do hereby
declare the nature of this invention to be as follows:-
:
Our improved domestic utensil has been designed for the purpose of heating
water and other liquids by means of a gas or oil flame, or by the use of a hot plate
over a fire, but not by the heat of an open fire.
Domestic utensils for this purpose have been before devised in which an annular
flue has been formed all around the body or water space, between it and an outer
_wall or casing. Now by our invention this annular flue is still retained, but the
outer wall or casing instead of being simply a sheet of metal is a hollow annular
chamber which is connected with the body or main water space by means of two
tubular connections, one near the bottom, and the other towards the top of such
water space, so as to more perfectly utilise the heat, promote the circulation of the
water, and thus lessen the consumption of fuel by heating the water more quickly.
We do not confine our invention to kettles, although that is probably the most
common form in which our, invention will be applied, and therefore that which we
have selected, whereby to illustrate our invention.

Street, St. Kilda, in the Colony of Victoria, Plumbers and Gasfitters, 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:
Our improved domestic utensil has been designed for the purpose of heating
water and other liquids by means of a gas or oil flame or by the use of a hot plate
over a fire but not by the heat of an open fire.
Domestic utensils for this purpose have been. before devised in which an annular
flue has been formed all around the body or water space, between it and an outer
wall or casing. Now by our invention this annular flue is still retained but the
outer wall or casing instead of being simply a sheet of metal is a hollow annular
chamber which is connected with the body or main water space by means of two
tubular connections one near the bottom and the other towards the top of such
water space so as to more perfectly utilise the heat, promote the circulation of
the water and thus lessen the consumption of fuel by heating the water
more quickly.
We do not confine our invention to kettles although that is probably the most
common form in which our invention will be applied and therefore that which we
have selected whereby to illustrate our invention.
Referring then to our drawing,
Figure 1 represents a kettle constructed according to our invention showing.one
half in outside elevation and the other half in vertical central section.
⚫ Figure 2 is a horizontal section of same on the line a, a in Figure 1.
In these Figures-A is the main cistern or water space of the kettle, and A¹ the
annular flue between it and the outer annular chamber A which is connected with
said cistern A by the tubular connection B near the top, and the tubular connec-
tion B¹ near the bottom. Near the top of the annular flue A¹ is formed on the
outer casing an outwardly projecting swage or bead A³ in which is punched a
number of draught holes A as shewn A is a conical shaped funnel projecting
.downwards from the top supply opening of the kettle to near the bottom of the
cistern A so as to cause the cold liquid to enter said cistern at that point. C is
the spout furnished with a hinged valve or clack C₁ at its top and having an
opening in it leading to the whistle C² which is affixed between it and the handle C³.
Said whistle is so adjusted as to give an alarm when the water or other liquid is
boiling.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is
•
The outer annular chamber A' connected with the inner main cistern A by the
tubular ways B and B¹ in combination with the annular flue A! which is between
them and which is provided with the draught holes A*, substantially as herein
described and explained and as illustrated in our drawing.
