Improvements in Pots or Vessels for Cooking, Preserving Fruit,
Melting Fat, Making Infusions or Decoctions, and for other like
Purposes.
1, WILLIAM WALTER GOOD of 38 Canterbury Road, Croydon, Surrey, Journalist,
do hereby declare the nature of this invention to be as follows:-
:―
The object of my invention is to construct a pot or vessel suitable for cooking,
preserving fruit, melting fat, making infusions or decoctions and for other like
purposes in a better manner and with less trouble and attention than pots or vessels
such as have been hitherto used for such purposes.
My improved pot is composed of an outer vessel or pot proper of a size suitable for
the particular purpose for which it is required, and having an internal cylinder or
liner extending from its upper edge to some distance down its interior, there being a
space between the sides of the liner and the pot. At one part of the liner, which
should bo the part which receives the least heat is an opening.
The outer vessel or
pot proper is provided with a lid or cover. The materials to be cooked, preserved,
melted, or otherwise acted upon are put in a separate pot or vessel which placed in
the pot proper and preferably rests on the bottom of same. The dimensions of this
inner pot are such that a space is left between the sides thereof and the sides of the
liner.
The pot is used as follows: The separate or inner pot having been placed in the
pot proper the latter is nearly filled with water and the lid or cover is put on. As
soon as the water begins to boil the steam rises therefrom and fills the space between
the top of the separate pot and the cover of the pot proper. The steam evolved in
the space between the pot proper and the liner finds its way through the opening
already described in the liner and also reaches the space above the top of the
separate pot. The result is that the contents of this pot are rapidly heated and
with little trouble and attention.
The liner is preferably fitted with a guard which prevents any liability of the
water rising into the inner pot owing to currents of water rushing round the two
sides of the outer pot and meeting at the opening in the liner.
For making infusions or decoctions, such for example as tea and coffee, water
is placed in the separate or inner pot and the tea or coffee introduced therein in
a bag or perforated vessel or otherwise.
For some purposes, such for example as for preserving moist fruits, when the
moisture from the contents of the inner pot or vessel should be allowed to escape
as it is evaporated. I fit this vessel with a cover or lid from which a tube is carried
up through an aperture in the cover of the outer pot. Thus the steam is kept
clear of the fruit while the surplus water evaporates; this is important in wet
seasons because strawberries and other soft fruit can be effectively preserved
notwithstanding the excessive amount of moisture they contain.
For large vessels such as would be used in manufacturing or large establishments
the pot proper may be connected with a feed cistern or a bird fountain which will
maintain the water level in the pot compensating for loss due to evaporation.

Improvements in Pots or Vessels for Cooking, Preserving Fruit,
Melting Fat, Making Infusions or Decoctions, and for other like
Purposes.
I, WILLIAM WALTER GOOD formerly of 38 Canterbury Road, Croydon in the
County of Surrey but now of 3 Astbury Road, Peckham in the same County,
Journalist, 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 my invention is to construct a pot or vessel suitable for cooking,
preserving fruit, melting fat, making infusions or decoctions and for other like
purposes in a better manner and with less trouble and attention than pots or vessels
such as have hitherto been used for such purposes.
My improved pot is composed of an outer vessel or pot proper of a size suitable for
the particular purpose for which it is required, and having an internal cylinder or
liner extending from its upper edge to some distance down its interior, there being a
space between the sides of the liner and the pot. At one part of the liner which
should be the part which receives the least heat is an opening. The outer vessel or pot
proper is provided with a lid or cover. The material to be cooked, preserved, melted
or otherwise acted upon are put in a separate-pot or vessel which is placed in the pot
proper and preferably rests on the bottom of same. The dimensions of this inner-pot-
are such that a space is left between the sides thereof and the sides of the liner.
The pot is used as follows: The separate or inner pot having been placed in the
pot proper the latter is nearly filled with water and the lid or cover is put on.
As
soon as the water begins to boil the steam rises therefrom and fills the space between
the top of the separate pot and the cover of the pot proper. The steam evolved-in-the
space between the pot proper and the liner finds its way through the opening already
described in the liner, and also reaches the space above the top of the separate pot.
The result is that the contents of this pot are rapidly heated, and with little trouble
and attention.
For making infusions or decoctions such for example as tea and coffee water is
placed in the separate or inner pot and the tea or coffee introduced therein in a bag
or perforated vessel or otherwise.
•
For some purposes, such for example as preserving moist fruits, when the moisture
from the contents of the inner pot or vessel should be allowed to escape as it is
evaporated I fit this vessel with a cover or lid from which a tube is carried up through
an aperture in the cover of the outer pot. Thus the steam is kept clear of the fruit
while the surplus water evaporates, this is important in wet seasons because straw-
berries and other soft fruit can be effectively preserved notwithstanding the excessive
amount of moisture they contain.
For large vessels such as would be used in manufacturing or large establishments
the pot proper may be connected with a feed cistern or a bird fountain which will
maintain the water level in the pot, compensating for loss due to evaporation.
Figure 1 of the accompanying drawings is a vertical section of a pot constructed
according to my invention, the said pot having a cover or lid fitted to the inner
vessel and being of a form or construction suitable for use in preserving moist
fraits. This figure shows both the outer and the inner vessels and the covers or
lids of same. Figure 2 is a vertical section showing the outer and inner vessels
and their respective covers separated from each other. Figure 3 is a half plan of
the outer and inner vessels without their covers.
a is the outer vessel or pot either of cylindrical form as shown or of oval or other
form. bis the internal cylinder or liner to same, extending from its upper edge to
some distance down the interior, there being a space c between the liner b and the
pot a.
At one part of the liner which should be the part that receives the least heat
is an opening d. The liner is shown as permanently fixed to the outer pot, but it

page_text: may be made removable so that the pot can, when desired, be converted into a
plain pot for ordinary purposes. e is the lid or cover to the vessel or pot a. fis
the inner pot or vessel in which the materials to be preserved, cooked, melted or
otherwise acted upon are put. This vessel has a perforated bottom flange g which
rests an the bottom of the outer vessel a and provides for a layer of water between
the bottom of the vessel and the bottom of the vessel a which comes in contact
with the fire. jis the lid or cover to the inner vessel which cover will only be
used when dealing with moist fruits or with other substances from which moisture
should be allowed to escape into the atmosphere. is a tube or 'outlet in the lid h
extending through an aperture & in the upper cover e; this provides for the escape
of the vapor evaporated from the surplus moisture in the materials under treatment,
while the steam evaporated from the water in the outer vessel is kept clear from
such materials. When the lid is not used the aperture k can be closed by a cork
or plug.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I claim in
respect of pots or vessels for cooking, preserving fruit, melting fat, inaking infusions
or decoctions and for other like purposes is :-
1. An outer pot or vessel formed at its upper part with an internal cylinder or
liner having an opening at one part of same, there being a space between the
sides of the liner and the pot, substantially as and for the purpose set forth.
2. An inner pot or vessel fitted with a lid or cover having a tube or outlet in
combination with an outer pot or vessel having a lid or cover with an aperture
through which said tube or outlet on the inner lid projects substantially as and
for the purpose set forth.
3. The improved pot or vessel hereinbefore described composed of an outer vessel
or pot and an inner vessel or pot adapted to each other and constructed substantially
as and for the purposes set forth.
