PROVISIONAL SPECIFICATION.
Improvements in the Construction of Kettles, Saucepans, and like
articles.
I, CHARLES SMITH, of 99 Chapel Street, Stratford, London, in the County of
Essex, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manner in which I construct kettles, saucepans and
like articles for containing liquid to be heated, whereby I am enabled to offer a
much larger heating surface for the water or liquid to be in contact with than is at
present possible with the existing ordinary kettles and like articles.
In carrying my invention into effect I construct the body of my kettle in the
usual or ordinary manner with the handle lid and spout attached in the usual well
known manner. The base or bottom of my kettle I construct with a corrugated
or fluted surface, either in the form of concentric rings or corrugations, or as plain
grooves or channelled serrations running across the surface of the metal. I attach
the metal base to the sides in the usual manner, and I form my corrugated, fluted
or grooved base out of sheet metal, by pressing in moulds, stamping, casting or
working up in any ordinary manner.
I fashion my base to suit any particular or peculiar form of kettle, of oval, round
or other form with equal advantage so far as regards the increased capacity for
heating the liquid quickly.
When constructing saucepans or other like articles I arrange the base to suit
the shape of the body of the saucepan, and cast it or construct it from plate metal
as may be desired for any particular requirement. I prefer to shape my corrugations
or fluted recesses and ribs such that the upper and lower surfaces of the serrations
may be of circular configuration of equal curvature throughout both for the top
and bottom of each channel or groove.
I do not limit the application of my invention to any particular purpose for
which kettles, saucepans and like vessels may be employed, but I apply my
grooved or corrugated base to any kind of vessel for heating liquid, constructed
out of metal porcelain, glass or other suitable material, for the purpose of increasing
the amount of heating surface offered to the contained liquid.
Dated this 31st day of March 1891.

COMPLETE SPECIFICATION.
Improvements in the Construction of Kettles, Saucepans, and like
articles.
I, CHARLES SMITH, of 99, Chapel Street, Stratford, London, in the County of
Essex, Engineer, 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 invention relates to the manner in which I construct kettles, saucepans and
like articles, for containing liquid to be heated, whereby I am enabled to offer a
much larger heating surface for the water or liquid to be in contact with, than is
at present possible with the existing ordinary kettles, and like articles.
In carrying my invention into effect, I construct the body of my kettle in the usual
ordinary manner, as shown in Figure 1 of the accompanying sheet of drawings, the
handle, lid, and spout, being attached in the usual well known manner.
The base

page_text: or bottom B of my kettle I construct with a corrugated or fluted surface either in
the form of concentric rings or corrugations, or as plain grooves or channelled
serrations bb running across the surface of the metal as shown in Figure 2 the
plan of the base. I attach the metal base to the sides in the usual manner, and I
form my corrugated, fluted, or grooved base out of sheet metal, by pressing in
moulds, stamping, casting, or working up in any ordinary manner.
I fashion my base to suit any particular or peculiar form of kettle, of oval, round,
or other form, with equal advantage so far as regards the increased capacity for
heating the liquid quickly.
When constructing saucepans as shown in elevation at Fig. 3, and in plan at
Figure 4, or other like articles, I arrange the base D to suit the shape of the
body C of the saucepan and cast it, or construct it from plate metal as may be
desired for any particular requirement. I prefer to shape my corrugations or
fluted recesses and ribs such that the upper and lower surfaces of the serrations d, d
may be of circular configuration of equal curvature throughout both for the top
and bottom of each channel or groove.
I do not limit the application of my invention to any particular purpose for
which kettles, saucepans and like vessels may be employed, but I apply my grooved
or corrugated base to any kind of vessel for heating liquid, constructed out of
metal, porcelain, glass or other suitable material, for the purpose of increasing the
amount of heating surface offered to the contained liquid."
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
(1) The construction of a kettle for heating water having the base formed with
a corrugated or fluted surface substantially as and for the purposes hereinbefore
described, and as set forth in the accompanying drawings.
(2) The construction of saucepans and other like vessels for heating liquids,
having grooved or corrugated bases, substantially as and for the purposes herein
described and as illustrated in the accompanying drawings.
Dated this 31st day of December 1891.
