PROVISIONAL SPECIFICATION.
Improvements in or connected with Sweetmeat and other
Moulds.
I, ALEXANDER HORN, of 9 Lemna Road, Leytonstone, in the County of
Essex, Manufacturer, do hereby declare the nature of the said invention to be as
follows:-
This invention relates to that description of mould, used more especially in the
manufacture of certain kinds of sweetmeats, which is formed of a sheet of india-
rubber or other suitable elastic material, having depressions in its upper surface into
which the material intended to form the sweetmeats is poured in a liquid state and
allowed to cool; and the object of my invention is to provide means whereby the
said cooling is expedited so that the mould can be emptied, and thereby made
available for a fresh operation much sooner than at present.
For this purpose I form the indiarubber or other elastic mould or "mat" hollow
or with channels through which a cooling medium such as water, air or other
suitable liquid or fluid can be passed or circulated in order to extract heat from the
sweetmeats contained in the depressions in the mould or "mat." According to one
arrangement I form the hollow by making a downwardly projecting rim or flange
round the edges of the mould or mat," and if necessary other downwardly
projecting ribs or flanges at other parts of the underside thereof.
When the mould
or " mat is placed with the lower edges of these rims, flanges or ribs resting on a
flat table or other smooth surface, the cooling medium may be circulated through
the hollow space formed by the under surface of the mould, the sides of the afore-
said rims or flanges, and the table or other surface on which the whole rests.. Or,
instead of using the table or other similar smooth surface to form the bottom of the
hollow space, such bottom may be formed of a sheet of indiarubber or other suitable
flexible material cemented or otherwise attached to the edges of the aforesaid rims,
flanges or ribs.
"
According to another arrangement, channels or passages of any suitable shape
may be formed in the body of the thick sheet of indiarubber composing the mould
or 66 mat such channels or passages being formed in the material between or
below the depressions in the mould as may be found most convenient or effective.
Whether the simple hollow space under the mould, or the channels or passages in
the body thereof be employed, suitable inlets and outlets are to be provided for the
entrance and exit of the cooling medium to and from such hollow space, channels
or passages.
In order to remove the sweetmeats from the depressions in the mould it has
heretofore been customary to bend the sheet of indiarubber or "mat" by hand so
that the upper side thereof becomes convex, whereby the dépressions therein are
caused to alter their form. in such manner as to loosen or eject the sweetmeats.
Now instead of bending the mould or "mat" by hand, I increase the pressure of.
the cooling medium in the space or channels and thereby cause the said mould.or
"mat" to assume the required convex form. Or, in cases where a cooling medium
is not employed, the required pressure may be obtained by the introduction of any
suitable fluid at any required temperature.
It is obvious that the above improvements are applicable to moulds for shaping
other substances besides sweetmeats.

Improvements in or connected with Sweetmeat and other
Moulds.
1, ALEXANDER HORN, of 9 Lenna Road, Leytonstone, in the County of
Essex, Manufacturer, do hereby declare the nature of the said invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement that is to say :-
This invention relates to that description of mould, used more especially in the
manufacture of certain kinds of sweetmeats, which is formed of a sheet of india-
rubber or other suitable elastic or flexible material having depressions in its upper
surface into which material intended to form the sweetmeats is poured in a liquid
state and allowed to cool; and the object of my invention is to provide means
whereby the said cooling is expedited so that the mould can be emptied, and thereby
made available for a fresh operation much sooner than at present.
For this purpose I form the indiarubber or other elastic or flexible mould or
"mat" hollow or with channels through which a cooling medium, such as water,
air or other suitable liquid or fluid can be passed or circulated in order to
extract heat from the sweetmeats contained in the depressions in the mould
or "mat."
And in order that the said.invention may be fully understood I will now proceed
to describe the same with the aid of the accompanying sheet of drawings the four
figures of which are sectional elevations of moulds constructed in accordance with
my invention..

"
According to one arrangement shown in Figure 1 I form the hollow by making
a downwardly projecting rim or flange A round the lower edges of the mould or
mat" B, and if necessary other downwardly projecting ribs or flanges such as A¹
at other parts of the underside of the said mould. When the mould or mat 15
placed with the lower edges of these rims, flanges or ribs A A¹ resting on or
cemented to or otherwise secured to a flat table D or other smooth surface the
cooling medium may be circulated through the hollow space or spaces E E formed
by the under surface of the mould B, the sides of the aforesaid rims, ribs, or
flanges A A, and the table D or other surface on which the whole rests. Or,
instead of using the table or other similar smooth surface to form the bottom of the
hollow space or spaces E E such bottom may be formed of a sheet of indiarubber
or other suitable flexible material F, shown in dotted lines in the figure, cemented
or otherwise attached to the edges of the aforesaid rims flanges or ribs.
According to another arrangement, illustrated in Figures 2 and 3, channels or
passages E E of any suitable shape may be formed in the body of the thick sheet
of indiarubber B composing the mould or "mat" such channels or passages being
formed in the material between or below the depressions B' in the moulds, as may
be found most convenient or effective.
Whether the simple hollow space under the mould, or the channels or passages in
the body thereof be employed, suitable inlets and outlets such as that. shown at G
in Figures 2 and 4 for example are to be provided for the entrance and exit of the
cooling medium to and from such hollow space, channels or passages.
In order to remove the sweetmeats from the depressions B' in the moulds, it has
heretofore been customary to bend the sheet of indiarubber or "mat" B by hand,
so that the upper side thereof becomes convex ; whereby the depressions B₁ therein
are caused to alter their form in such manner as to loosen or eject the sweetmeats.
Now instead of bending the mould or "mat" by hand, I sometimes arrange it so
that it can be bent into the required convex form by increasing the pressure of the
liquid or fluid cooling medium in the spaces or channels below or in the body of the
mould. This is illustrated in Figure 4 in which case the rims, ribs or flanges A A¹
are secured by cementing for example to the table D. The cooling medium is caused

page_text: to circulate through the spaces E E at a comparatively low pressure while the sweet-
meats are being moulded in the depressions B¹; but when the sweetmeats are ready
for removal, the pressure on the cooling medium in the spaces E E is increased by
bringing it into communication with a reservoir of cooling medium placed at a higher
level than that from which it had previously been supplied, or by wholly or partially
closing a tap governing the outlet from the spaces E E, the height of supply
remaining unaltered; or the increased pressure may be obtained by any other
suitable means.
In cases where a cooling medium is not employed the required pressure for pressing
up the mould may be obtained by the introduction of any suitable fluid at any
required temperature and pressure into the spaces E E.
It is obvious that the above improvements are applicable to moulds for shaping
other substances besides sweetmeats.
Similar letters of reference relate to like parts in all the figures of the drawing.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
First. A sweetmeat or other mould of indiarubber or other elastic or flexible
material so constructed that a liquid or fluid cooling medium can be passed through
or beneath the same substantially as described.
Second. A sweetmeat or other mould of indiarubber or other elastic or flexible
material constructed with hollows or channels, such as those marked E E in the
drawings, substantially as and for the purposes specified.
Third. A sweetmeat or other mould of indiarubber or other elastic or flexible
material, so constructed that the depressions therein, in which the sweetmeat or.
other material is moulded, can be pressed or bent into a more or less convex form
by fluid pressure, substantially as described with reference to Figure 4 of the
drawings, and for the purpose specified.
