WILLIAM ROBERT LAKE, of tho firm of Haseltine, Lake and Co., Patent Agents,
Southampton Buildings, London, " IMPROVEMENTS IN THE MANUFACTURE OF
SUGAR" [A cominunication to him from abroad by Leopold May, of Ungarisch,
Ostra, in the Empire of Austria,]
Hitherto sugar in small lumps known under the name of cube sugar, has been
produced either (first) by sawing sugar loaves into slabs, then cutting these slabs
into strips, and finally splitting or nipping the said strips into pieces of the form
of cubes, dominoes or prisms; or (secondly) by producing flat cakes or plates of
sugar and then reducing their size as above; or (thirdly) producing strips of sugar
which had to be split or nipped to obtained the desired pieces.
The object of this invention is to provide means for producing, directly from the
sugar liquor, pieces in the form of cubes, prisms, dominoes, or in any other desirable
shape suitable for the table, which sugar, after being completely refined, is ready for
the market without having to be further reduced in size in any manner, that is to
say, without having to be either sawn, or nipped, or otherwise split or broken.
For the purpose of obtaining this result I make use of moulds which may
consist of strips (preferably of sheet metal) suitably stamped or otherwise formed
and arranged side by side but it is evident that without departing from the
substance of this invention, the construction of the moulds may be greatly modified.
In a claying or blanching apparatus, case, carriage, or the like of any desirable
shape designed to receive the sugar liquor, there are arranged in tiers or stories, a
number of partitions or moulds fitting the case and placed close to each other. The
building up of these tiers of moulds is to be commenced from the bottom row,

page_text: each consecutive tier being placed crosswise on the top of the previous one and so
on until the whole case, apparatus, carriage or the like is completely filled up to
the top. The case containing the moulds is then filled with sugar liquor in the
same, manner as the ordinary cones or loaf moulds in the manufacture of loaf
sugar are filled. As soon as the liquor has properly crystallized in the moulds the
sugar is blanched or liquored either by the aid of a centrifugal apparatus or by
any known process in use in the manufacture of loaf sugar. After the blanching,
the sugar is taken out of the mould and dried.
By arranging the tiers of moulds consecutively crosswise over each other the
single tiers of sugar can be easily separated from each other during the process of
taking the blanched sugar out of the moulds. When the pieces of sugar to be
formed are of large size it is preferable to arrange a sieve between the tiers of
partitions as thereby the tiers can be more readily separated from each other and
this arrangement does not interfere with the blanching. In this case it is not
necessary to placo the adjacent tiers crosswise or at a right angle to each other.
It is obvious that the metal partitions or strips. arranged side by side form a
large number of receptacles in which, after the sugar liquor has been poured in,
and according to the configuration of the said strips, tho sugar sets in the form of
cubes, dominoes, prisms, or the like. It is also obvious that when the moulds are
taken asunder by displacing the metal strips the sugar will fall out in the said
shape of cubes, dominoes, prisms, or the like.
By suitably impressing or embossing parts of the surface of the said metal
strips, cach piece of sugar formed in the said moulds will be provided with any
desired marks.

by the said William Robert Lake in the Great Seal Patent Office on the
24th April 1883.
WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and C° Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN THE MANUFACTURE OF
SUGAR" A communication to mo from abroad by Leopold May, of Ungarisch,
Ostra, in the Empire of Austria.
This invention relates to the manufacture of sugar.
Hitherto sugar in small lumps known under the name of cubo sugar has been
produced either by sawing sugar loaves into slabs, then cutting these slabs into
strips, and finally splitting or nipping the said strips into pieces of the form of
cubes, dominoes or prisms;. by producing flat cakes or plates of sugar and then
reducing their sizo as above; or by producing strips of sugar which had to be
split or nipped to obtain the desired pieces
The object of this invention is to provide means for forming directly from the
liquid sugar, pieces in the form of cubes, prisms, dominoes, or in any other desirablo
shape, which sugar after being completely refined is ready for the market without
having to be further reduced in size in any manner, that is to say, without having
to be either sawn, nipped or otherwise split.
For the purpose of obtaining this result I make use of apparatus hereinafter
described.
In the accompanying drawing.
Figure 1 is a perspective view of a mould constructed according to this invention.
Figure 2, is a similar view illustrating a modification and
Figure 3 is a perspective view drawn to a reduced scale showing a case filled
with the said moulds.
The moulds may consist of strips (preferably of sheet metal) suitably stamped or
otherwise formed, and arranged side by side; it is evident that without departing
from the nature of this invention the construction of the moulds may be greatly
modified.
In a claying or blanching apparatus, case, carriage or the like of any desirable
shape designed to receive the sugar liquor, there are arranged in tiers (for instance
as illustrated in Figure 3) a number of partitions or moulds fitting the said
case and placed close to each other. The building up of these tiers of moulds is
commenced from the bottom row, each consecutive tier being placed crosswise on
the top of the one below it, as shown in Figure 2, and so on until the whole case,
apparatus, carriage or the like is completely filled to the top The case containing
the moulds is then filled with sugar liquor in the same manner as the ordinary
cones or loaf moulds in the manufacture of loaf sugar are filled. As soon as the
liquor has properly crystallized in the moulds the sugar is blanched or liquored
either by the aid of a centrifugal apparatus or by any known process in use in the
manufacture of loaf sugar. After the blanching, the sugar is taken out of the
mould and dried
By arranging the tiers of moulds consecutively crosswise over each other
the single tiers of sugar can be easily separated from each other during the
process of taking the blanched sugar out of the moulds. When the pieces of
sugar to be formed are of large size it is preferable to arrange a sieve between
the tiers of partitions as shown in Figure 1, as thereby the tiers can be more
readily separated from each other and this arrangement does not interfere with
the blanching. In this case it is not necessary to place the adjacent tiers crosswise
or at a right angle to each other,

It is obvious that the metal partitions or strips arranged side by side form a
large number of receptacles in which, after the sugar liquor has been poured in and
according to the configuration of the said strips, the sugar sets in the form of
cubes, dominoes, prisms, or the like.
It is also obvious that when the moulds are taken asunder by displacing the
metal strips the sugar will fall out in the said shape of cubes, dominoes, prisms or
the like.
By suitably impressing or embossing parts of the surface of the said metal strips
cach piece of sugar formed in the said moulds may be provided with any desired
marks.
Having thus fully described the said invention as communicated to me by my
foreign Correspondent, and the manner of performing the same, I wish it understood
that I claim.
First. The manufacture of sugar in the form of cubes, plates, prisms, dominoes,
or other suitable shapes in small pieces, substantially as, and for the purpose,
'specified.
Second. The employment of the partitions substantially as described with
-reference to the drawing, and-for the purpose specified..
Third. The method of producing on sugar in small pieces of any desired form
trade marks, numbers, letters or other suitable marks, substantially as described.
In witness whereof I the said William Robert Lake, have hereunto set my
hand and seal-this Twenty-fourth day of April in the year of Our Lord One
thousand eight hundred and eighty three.
