CHARLES LYLE and JOHN LYLE, both of 37 Mincing Lane, London E.C. Sugar
Refiners, do hereby declare the nature of this invention to be as follows:-
Hitherto, in making Lump Sugar by means of open-ended moulds placed in a
centrifugal machine, it has been necessary, before filling the moulds with masse-cuite
and allowing the sugar to set in them, to fix the moulds in such a way as to prevent
the escape of the syrup and this has been accomplished either by tightly jointing each
mould to a specially prepared table or to a moveable bottom, or by placing the moulds
one above the other to a convenient height and resting the bottom ones on a flat
surface to which and to one another the moulds were jointed by a suitable arrange-
ment. This part of the process is very laborious and the cause of considerable
expense in the manufacture of the lump sugar. By our invention we dispense with
the making of tight joints and generally cheapen and expedite the process. Instead
of jointing the moulds, we provide vessels into which the empty moulds are placed
with the open ends up and down. These vessels are so constructed that a convenient
number of the moulds fit closely into them so as to leave as little open space between
and around them as possible. The masse-cuite is poured into the vessels thus prepared
so as to fill them completely, thereby filling the moulds inside. After the sugar has
set, the moulds with their contents are taken out of the vessels and treated in the
Centrifugal Machines in the usual way. If it is desired to liquor the sugar the moulds
may be replaced in the vessels for this purpose. The vessels may be provided with a
jacket or casing through which cold water may be made to pass in order to expedite
the cooling & setting.

Improvements in the Manufacture of Lump Sugar.
CHARLES LYLE and JOHN LYLE, both of 37 Mincing Lane, London, E.C. Sugar
Refiners, 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 :-
Hitherto, in making lump sugar by means of open-ended moulds and centrifugal
machine treatment, it has been the custom, before filling the moulds with masse-cuite
and allowing the sugar to set in them, to fix the moulds in such a way that the syrup
could not escape from the open ends; and this has been accomplished either by tightly
jointing each mould to a specially prepared table or to a moveable bottom, or by
placing the moulds one above another to a convenient height and resting the bottom
ones on a flat surface to which and to one another the moulds were jointed by a
suitable arrangement. This part of the process is very laborious and the cause of
considerable expense in the manufacture of lump sugar. By our invention we
dispense with all jointing of the moulds and generally cheapen and expedite the
process.
We provide a trough or vessel into which the empty moulds are placed in such a
way that when masse-cuite is poured into the vessels the moulds are completely filled
up by it. These vessels are so constructed that a convenient number of the moulds
fits closely into them so as to leave as little open space between and around them as
possible, thus minimizing the waste of sugar. When the vessels are packed with
moulds we pour masse-cuite into them so that the contained open-ended moulds are
completely filled with the sugar. After the sugar has set, the moulds with their
contents are taken out of the vessels and treated in the Centrifugal Machines in the
usual manner. It will thus be seen that by our process the moulds are filled with a
minimum of waste, without the necessity of jointing them.
If it is desired to liquor the sugar after it has been dried in the Centrifugal
Machines, the filled moulds may be replaced in the vessels for this purpose. The
vessels may be provided with a jacket or casing through which cold water may be
made to pass in order to expedite the cooling.
In order that our invention may be better understood, we subjoin drawings
illustrative of modes of carrying out our invention. Figs. 1 & 2 are respectively a
plan & section showing a trough a open at the top and having a door b at one side for
convenience in packing & removing the moulds. In this trough the moulds m are
placed tier upon tier with open ends up and down so that they are filled with masse-
cuite poured in from above as shown by the arrow. Figs. 3 & 4 show a plan and
section of a trough a with open top wider than the bottom so as to receive moulds m
of a wedge shape, which it is often found convenient to adopt. In this case also the
moulds are packed vertically & filled from above. Fig. 5 shows a section where the

page_text: moulds m are packed horizontally into the trough a in such a way as to leave a
passage p down which the masse-cuite is poured thence travelling in a horizontal
direction to fill up the moulds.
The drawings are not intended to show all the modes in which our invention may
be carried out, as it is manifest that the shape and size of the troughs and the manner
of packing, may be varied to suit the shape and size of the moulds which may be used
and the general circumstances under which the process may be worked.
Having now particularly described & ascertained the nature of our said invention,
and in what manner the same is to be carried out, we desire to state that we do not
claim the use of open-ended moulds, but what we do declare to be new and claim is :-
1
The method of filling open-ended moulds with masse-cuite, in the manufacture
of lump sugar, by placing the moulds in a suitably shaped trough or vessel into
which the masse-cuite is poured, substantially as hereinbefore described.
