New or Improved Cooling Apparatus, more especially applicable to
the Manufacture of Chocolate Confectionery.
I, ALEXANDER HORN, Managing Director of The Hackney Wick Confectionery
Works, London, do hereby declare the nature of the said invention to be as
follows:-
This invention relates to cooling apparatus more especially applicable to the
cooling of certain articles of chocolate confectionery while the same are being
manufactured; but such apparatus is also applicable to other purposes.
In the manufacture of chocolate creams and other chocolate covered confectionery
for example, it is found impracticable to carry on such manufacture in an
atmosphere the temperature of which exceeds a certain degree; but by the use of
my invention I am enabled to carry on the manufacture whatever may be the
temperature of the surrounding atmosphere.
The apparatus consists of a metallic watertight box of oblong or other suitable
shape adapted to contain cold brine, or other cooling liquid or ice. The box is
supported by any suitable means a short distance above the work table on which
the chocolate creams are prepared by the operative. As the creams are covered
with chocolate they are placed on a metallic plate which is gradually pushed, as it
is covered with the creams, in under the cooling box, where the chocolate is
subjected to the cooling action of the cold brine or ice in the box above, and is
thereby cooled down before it can be spoilt by the heat of the atmosphere pervading
the workroom. By the time the plate, covered with the creams, has been pushed
to the other end of the box they are sufficiently cooled and set to prevent any
chance of injury, and they may then be removed and set aside for further
hardening.
When it is intended to use cold brine or other cooling liquid, the box may be
closed at the top except as to a hole for introducing and removing such liquid.
When ice is to be employed the box should be provided with a removeable cover.
When the cooling liquid has become too warm or the ice in the box has melted,
the liquid or ice-water is removed and fresh cold liquid or ice put into the box.
In order to collect any condensed moisture that may settle on the surfaces of the
box, suitable gutters may be provided to carry it away, and to facilitate the
collection of any such moisture that may condense on the under side of the box,
and to prevent the same from falling on to the creams or other confectionery, the
said under side or bottom of the box may be made sloping so that the moisture
will run down to and be carried away by a gutter at the lower end of the slope.
The box is preferably made of thin metal, such as tinued iron or copper, but it
may be made of any other suitable material.

New or Improved Cooling Apparatus, more especially applicable to
the Manufacture of Chocolate Confectionery.
I, ALEXANDER HORN, Managing Director of The Hackney Wick Confectionery
Works, London, 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, that is to say :-
This invention relates to cooling apparatus more especially applicable to the
cooling of certain articles of chocolate confectionery while the same are being
manufactured; but such apparatus is also applicable to other purposes.
In the manufacture of chocolate creams and other chocolate-covered confectionery
for example, are at present practised, it is found impracticable to carry on such
manufacture in an atmosphere the temperature of which exceeds a certain degree ;
but by the use of my invention I am enabled to carry on the manufacture whatever
may be the temperature of the surrounding atmosphere.
In the drawings hereto annexed Figure 1 is an end elevation, Figure 2 a
longitudinal vertical section taken on the line 1-1 of Figures 1 and 3, and Figure 3
a transverse vertical section taken on the line 2-2 of Figure 2, of an apparatus
constructed in accordance with my invention, and Figure 4 is a half transverse
section of a similar apparatus with insulating material applied to its outer surface.
The apparatus consists of a metallic water-tight box or chamber A of oblong
or other suitable shape adapted to contain cold brine, ice, or other cooling liquid
or material. The box A is supported by any suitable means a short distance above
the work-table B on which the chocolate creams are prepared by the operative for
example, the sides of the box may be extended down below the bottom A' for this
purpose as shown at A'. As the creams C are covered with chocolate, they are
placed on a metallic plate D which is gradually pushed, as it is covered with the
creams, in under the cooling box A where the chocolate is subjected to the cooling
action of the cold brine, or ice, in the box above, and is thereby cooled down
before it can be spoilt by the heat of the atmosphere pervading the workroom.
By the time the plate D, covered with the creams C, has been pushed to the other
end of the box A they are sufficiently cooled and set to prevent any chance of
injury, and they may then be removed and set aside for further hardening.
When it is intended to use cold brine or other cooling liquid the box A may be
closed at the top by a fixed cover as shown at A³ except as to an opening A' for
introducing and removing such liquid. This opening may be surrounded by a
tubular extension A' to prevent splashing over of the liquid in the box A when
carrying the same from place to place, and this extension A³ may be closed at top
by a cap or cover A. When ice is to be employed, it may be more convenient to
provide the box with a removable cover. When the cooling liquid has become too
warm, or the ice has melted, the liquid, or ice water, is removed from and fresh
cold liquid, or ice, put into the box.
In order to collect any moisture that may be condensed on the outer surfaces of
the box A, suitable gutters E may be provided to carry it away, and to facilitate
the collection of any such moisture that may condense on the underside of the
bottom of the box, and to prevent the said moisture from falling on to
the creams C or other confectionery, the said underside or bottom of the box is
preferably made sloping as shown at A', in Figures 1 and 3, so that the moisture
will run down to and be carried away by a gutter F placed at the lower end of
each slope.
In order to prevent as much as possible unnecessary loss of cooling effect by the
transmission of heat to the outer surfaces of the box A, the said surfaces may be
covered with felt or other suitable bad conductor of heat as shown at G for

page_text: example in Figure 4, the said bad conductor of heat being enclosed in an outer
casing H or not as may be preferred.
The box A, as also the casing H (when the latter is employed) are preferably
made of thin metal such as tinned iron. or copper, but they may be made of any
other suitable material.
Similar letters of reference relate to like parts in all the figures of the drawings.
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 :-
First. The new or improved cooling apparatus which consists of a box or
chamber containing cold brine, ice, or other suitable cooling liquid or material,.
arranged and adapted so as to exert a cooling effect upon chocolate confectionery
or other articles placed beneath the same, substantially as described.
Second. The new or improved cooling apparatus which consists of a box or
chamber adapted to contain cold brine, ice, or other suitable cooling liquid or
material, and to be employed substantially as described.
Third. In cooling apparatus of the kind herein described, the use of gutters.
for the purpose of conveying away the moisture condensed on the surfaces of the
box or chamber containing the cooling medium, substantially as described with
reference to the accompanying drawings.
Fourth. In cooling apparatus of the kind herein described, making the bottom:
of the box or chamber intended to contain the cooling medium, sloping,
substantially as described with reference to the accompanying drawings, and for the
purpose specified.
