PROVISIONAL SPECIFICATION.
An Appliance for the Storage of Ice and for Using the same Advan-
tageously for the Cold Storage of Food and other Matters.
I, FRANCIS THOMAS BOND, of 3, Beaufort Buildings, in the City of Gloucester,
Doctor of Medicine, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to employ the cooling properties of ice in the
most effective way for the purpose of refrigerating articles of food or other matters
which require to be kept at a low temperature to prevent their decomposition.
For the purposes of this invention I construct a cylindrical vessel, open at the
top, of any convenient size, and of any suitable material, but preferably of wood
or other substance which has a low conducting power and is not otherwise unfit:
Inside this vessel I fix concentrically, by attachment of the two vessels at their
upper margins, directly or by medium of a flange, a second cylindrical vessel
of somewhat smaller size. This second vessel is so constructed that at its lower
part there is formed a cylindrical chamber, corresponding as nearly as may be,
in diameter with the vessel itself and about one tenth of its height, the roof
of the chamber forming the floor of the upper of the two chambers into which the
vessel is now divided. The lower chamber I use for the reception of waste water and
the upper for the storage of the articles to be refrigerated and of the ice. In
the centre of the roof of the water chamber I make a round aperture of about
two inches diameter and in the lower part of the chamber I make another
aperture with which I connect, in a water-tight manner, a tube, which I carry
horizontally outwards through the wall of the outermost vessel, for the purpose
of conducting from the chamber any water or other liquid that may find its way
into it. The storage chamber is formed either wholly of sheet metal or of some
less conducting material such as wood or papier maché.
be constructed wholly of metal.
The water vessel must
I then construct a third cylindrical vessel, of smaller size than the storage
chamber but large enough to hold a sufficient amount of ice for the purpose
equired, and in the centre of the floor of this vessel I make an aperture somewhat
ess in size than that in the roof of the water chamber. I support this latter
essel, which I use for containing the ice, on a shelf or in any other convenient
ray in the middle of the storage chamber and as near as may be to the top
f it. To the margin of the aperture in the floor of the ice vessel I attach a
ollar of such size that it will just drop into a vertical metal pipe connected with
he aperture in the roof of the water vessel, which thus serves to conduct the
elted water away from the ice vessel into the water chamber. The ice vessel
ad the tube connecting it with the water vessel are detachable from one another
nd from the water vessel, so that the whole of the storage chamber can easily
e got at for purposes of cleaning, etc.
Finally, I pack the space between the two outer vessels with some convenient
aterial of low conducting power, such as hair, wool. feathere
vecotahl el

page_text: or silicate slag wool, and I provide both the ice chamber and the whole appliance
with suitable covers, made of as low conducting material as possible.
In order to delay the passage of the water as it flows down the central tube
I form a flange or spiral thread on its inside, or I make the tube itself in a spiral
form, such as is known as cable tubing, so that the water is compelled to flow
in a spiral manner down the tube instead of down straight. Or I attain the same
object by packing the interior of the tube with some porous material.
To use the appliance thus constructed, the ice vessel is filled with ice and placed
in position on top of the central tube and the articles to be refrigerated are
placed around or beneath it, on the floor of the chamber or on loose shelves,
which may be adapted to rest on brackets attached to the walls of the storage
chamber. If a larger quantity of ice than the ice vessel will hold is required to
be stored the ice vessel may be removed and the ice may be stored on the floor
of the storage chamber itself.
The efficiency of this arrangement will depend on the following conditions;
(1) the construction of the outermost vessel and of so much of the innermost
vessel as forms the wall of the storage chamber of a material of low conducting
power; (2) the size of the space between the middle and the outermost vessel
and the quantity and low conducting power of the packing used to fill it; (3) the
size of the ice vessel and the quantity of ice placed within it, and (4) the accumu
lation of the cold waste water in the water chamber, the cooling power of which
is thus used in helping to cool the storage chamber.
But, whatever the amount of ice that may be used for the purpose it will be
used under the most favourable conditions because: (a) it will be in the centre
of the atmosphere to be cooled; (b) the appliance being cylindrical in shape offers
the smallest amount of outer surface for radiation and conduction of heat into
it; (c) the ice being kept separate from the water produced from it by melting,
is under better control and can be used to better effect than if this were not
so; (d) the melted ice-cold water is utilised to the fullest practicable extent for
refrigerating purposes as it trickles from the ice vessel and when stored in the
water vessel.
In order to allow of the accumulation of water in the water chamber I attach
a cock to the outlet tube therefrom, so as to allow of its being run off when
required and to prevent undue accumulation of water in the chamber and its
flowing back into the storage chamber I insert a waste pipe in the upper part
of the chamber by which the water can flow away to the outside of the appliance
when it reaches a certain level.
An Appliance for the Storage of Ice and for Using the same Advan-

I, FRANCIS THOMAS BOND, of 3, Beaufort Buildings, in the City of Gloucester,
Doctor of Medicine, 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 employ the cooling properties of ice in the
most effective way for the purpose of refrigerating articles of food or other matters
which require to be kept at a low temperature to prevent their decomposition.
For the purposes of this invention I construct a cylindrical vessel, open at the

page_text: top, of any convenient size, and of any suitable material, but preferably of wood
or other substance which has a low conducting power and is not otherwise unfil.
Inside this vessel I fix concentrically, by attachment of the two vessels at their
upper margins, directly or by medium of a flange, a second cylindrical vessel
of somewhat smaller size. This second vessel is so constructed that at its lower
part there is formed a cylindrical chamber, corresponding as nearly as may be,
in diameter with the vessel itself and about one tenth of its height, the roof of the
chamber forming the floor of the upper of the two chambers into which the vessel is
now divided. The lower chamber I use for the reception of waste water and
the upper for the storage of the articles to be refrigerated and of the ice. In
the centre of the roof of the water chamber I make a round aperture of about
two inches diameter and in the lower part of the chamber i make another
aperture with which I connect, in a water tight manner, a tube, which I carry
horizontally outwards through the wall of the outermost vessel, for the purpose
of conducting from the chamber any water or other liquid that may find its way
into it. The storage chamber is formed either wholly of sheet metal or of some
less conducting material such as wood or papier maché. The water vessel must
be constructed wholly of metal.
I then construct a third cylindrical vessel, of smaller size than the storage
chamber but large enough to hold a sufficient amount of ice for the purpose
required, and in the centre of the floor of this vessel I make an aperture somewhat
less in size than that in the roof of the water chamber. I support this latter
vessel, which I use for containing the ice, on a shelf or in any other convenient
way in the middle of the storage chamber and as near as may be to the top
of it. To the margin of the aperture in the floor of the ice vessel I attach a
collar of such size that it will just drop into a vertical metal pipe connected with
the aperture in the roof of the water vessel, which thus serves to conduct the
melted water away from the ice vessel into the water chamber. The ice vessel
and the tube connecting it with the water vessel are detachable from one another
and from the water vessel, so that the whole of the storage chamber can easily
be got at for purposes of cleaning &c.
Finally, I pack the space between the two outer vessels with some convenient
material of low conducting power, such as hair, wool, feathers, vegetable fibre
or silicate slag wool, and I provide both the ice chamber and the whole appliance
with suitable covers, made of as low conducting material as possible.
In order to delay the passage of the water as it flows down the central tube
I may form a flange or spiral thread on its inside, or I may make the tube itself in a
spiral form, such as is known as cable tubing, so that the water is compelled to flow
in a spiral manner down the tube instead of down straight. Or I may attain the
same object by packing the interior of the tube with some porous material, such
as sand.
To use the appliance thus constructed, the ice vessel is filled with ice and placed
in position on top of the central tube and the articles to be refrigerated are
placed around or beneath it, on the floor of the chamber or on loose shelves,
which may be adapted to rest on brackets attached to the walls of the storage
chamber. If a larger quantity of ice, than the ice vessel will hold is required to
be stored the ice vessel may be removed and the ice may be stored on the floor
of the storage chamber itself.
The efficiency of this arrangement will depend on the following conditions;
(1) the construction of the outermost vessel and of so much of the innermost
essel as forms the wall of the storage chamber of a material of low conducting
power; (2) the size of the space between the middle and outermost vessel
nd the quantity and low conducting power of the packing used to fill it; (3) the
ize of the ice vessel and the quantity of ice placed within it, and (4) the accumu-
ation of the cold waste water in the water chamber, the cooling power of which
s thus used in helping to cool the storage chamber.
But, whatever the amount of ice that may be used for the purpose it will be

page_text: used under the most favourable conditions because (a) it will be in the centre
of the atmosphere to be cooled; (b) the appliance being cylindrical in shape offers
the smallest amount of outer surface for radiation and conduction of heat into
it; (c) the ice being kept separate from the water produced from it by melting,
is under better control and can be used to better effect than if this were not
so; (d) the melted ice-cold water is utilised to the fullest practicable extent for
refrigerating purposes as it trickles from the ice vessel and when stored in the
water vessel.
In order to allow of the accumulation of water in the water chamber I attach
a cock to the outlet tube therefrom, so as to allow of its being run off when
required; and to prevent undue accumulation of water in the chamber and its
flowing back into the storage chamber I insert a waste pipe in the upper part
of the chamber by which the water can flow away to the outside of the appliance
when it reaches a certain level.
The general construction of the appliance thus described is indicated in the
drawing appended hereto, which represents a vertical section of it through the
middle. In this section A is the outer cylindrical container; B the interior
storage chamber; G the space between the two, filled with packing material of
low conducting power; L the ice vessel, with E the tube leading therefrom to K,
the water chamber, from which the water is carried off by the tube C, having the
tap D at its outlet. H, H are movable shelves, resting on brackets, for the
purpose of supporting the articles to be refrigerated. Fis a cover, made to.fit
as nearly air tight as convenient to allow of its being taken off and replaced when
required.
Where it is required to store a larger quantity of ice than the ice vessel D
will hold, this latter may be removed, together with the vertical tube E, and the
ice may be placed on the floor of the chamber B, and the articles to be refrigerated
on top of it, on the shelves or otherwise.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
(1) The arrangement of a cylindrical vessel, with a cover, made of low con-
ducting material, inside of which is a second cylindrical vessel somewhat less
in diameter than the first, the space between the two being packed with hair,
wool or other low conducting material, and having a cylindrical box for holding
ice, in the upper part of the said inner vessel, connected by a vertical pipe for
carrying the melted water to a cylindrical chamber at the bottom of the vessel,
with an outlet from this latter, by which the water can be run off, the whole being
constructed substantially in the manner hereinbefore described.
(2) The use of the said vessel without the ice container, the ice being in that
case stored on the floor of the inner vessel, through the hole in the floor of which
the water drains into the water chamber, the special ice container and vertical
tube having been removed.
