IMPROVED FORMS OF KETTLES AND SAUCEPANS
Year: 1886

page_text: I, GEORGE ABRAHAM GOODWIN of 2 Victoria Mansions Victoria Street Westminster
in the City of London, Civil Engineer do hereby declare the nature of my invention
for an
"IMPROVED FORMS OF KETTLES AND SAUCEPANS to be as follows: -
My invention relates to an improved construction of kettle or saucepan for the
heating or boiling of liquids and has for its object the quick transmission of the
heat of the fuel to the liquid in the kettle or saucepan, obtaining a relatively broad
and large water space all round the bottom so as to prevent the material burning
through, obtaining a large heating surface without dedtracting much from the
capacity of the kettle or saucepan, making the bottom corrugated so that the
constant movement of the material due to expansion and contraction will tend to
keep the deposits of lime etc from adhering to the inner surface and retaining.
facilities for the proper cleaning of all parts.
I carry out my said invention preferably in the following manner.
The bottom of the kettle or saucepan is made of a partly horizontal and recessed
form and corrugated the junction of the two being well rounded and free from.
sharp corners, the top of the recessed portion I connect to the lower end of one or
more tapered fire tubes or flues which pass through the kettle or saucepan and out
at the sides, these tubes or flues are not vertical but inclined so as to pass as much
as possible through the liquid and not through the vapour or steam.
In large sizes of kettles or saucepans I would further provide water tubes across
the fire tubes or flues to further abstract the heat from the fuel and increase the
circulation.

page_text: I, GEORGE ABRAHAM GOODWIN of 2 Victoria Mansions Victoria Street in the City
of Westminster 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 :-
My invention relates to an improved form of construction of kettles or saucepans
or such like articles that are used for beating or boiling of liquids and has for its
object the rapid transmission of the heat of the fuel to the liquid in the kettle or
saucepan (herinafter referred to as the receptacle); effecting this without materially
detracting from the capacity of the receptacle; obtaining a relatively broad & large
water space all round the bottom so as to mitigate against the probabilities of the
bottom getting furred up & burning through; obtaining a large heating surface by
dishing or recessing the bottom & corrugating it-and which owing to its constant
movement due to the expansion & contraction of the material-will prevent the
deposits of lime on the inside and of soot on the outside-from adhering-so
ensuring a free passage for the heat.
I carry out my said invention preferably in the following manner, and for the
purpose of description refer to the accompanying drawing.
The bottom of the receptacle is made partly flat as at-a-and partly recessed
& corrugated as at 6 the junction of the two being well rounded as at b, and free
from sharp corners, the top of the recessed portion b I connect to the lower end of
one or more taper fire tubes or flues c which pass through the receptacle and out at
the side as at c₁ these tubes are not vertical but inclined so as to pass as much as
-possible through the liquid & not through the vapour or steam.
In large sizes of receptacles I further provide water tubes across the fire tubes or
flues so as to further abstract the heat from the fuel & increase the circulation one
of such water tubes being shewn at c₂.
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
1st. A kettle, saucepan or other such like receptacle with a combined horizontal
and recessed corrugated bottom combined with one or more fire tubes or flues with
or without cross water tubes substantially as and for the purpose described and
shown in the drawing.
