Office of the Commissioners of Patents on the 21st November 1882.
THE
HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN APPARATUS FOR
MANUFACTURE OF SUGAR IN LUMPS, PIECES, OR BLOCKS" [A communication to
him from abroad by La Société Lebaudy frères, of Paris, France]
This invention relates to improvements in the apparatus for the manufacture of
sugar in lumps, pieces or blocks, described in the Specification of former Letters
Patent dated 4th March, A.D. 1882, No. 1055.
The present improvements relate more particularly to the following points, that
is to say-First, the mode of manufacturing the plates or tables of the apparatus,
based chiefly upon the employment of movable partitions or plates independent of
the metal plates which form the bottom of the said tables; these partitions are
capable of being fixed in the frames which contain them, at different distances from
one another according to the thickness it is desired to give to the pieces of sugar.
Second, the removal of the pieces from the moulds, based upon the employment, at
the extremities of each frame of the apparatus, of a peculiar arrangement of border
or edge plates, combined with the use of plates of trapezoidal section which permit
the loosening of the mass and the extraction of the plates, and of the pieces of
sugar contained in the apparatus to be effected with facility. Third, the evacuation
of the syrup draining from the pieces of sugar, by means of apertures formed trans-
versely in each frame below the wire gauze or perforated sheet metal in the lower
part of the apparatus; the juxtaposition of these apertures when the frames are
placed together constituting draining gutters or channels which are open at the two
Price G1

page_text: opposite faces of the apparatus and which are placed in communication with an
apparatus for creating a vacuum.
The mode of manufacturing the tables is as follows, that is to say:-As described
in the said former Specification I make the transverse partitions of the said tables
of metal plates independent of the plate which forms the bottom of the table; but
according to the present invention these movable partitions are of a width equal
to the distance between the tables and are retained in position at the lower part
by a notch or groove formed in the frame and at the top by a spur or projection
entering a notch made in the plate which forms the bottom of the table. The wire
gauze or perforated sheet metal in the lower part of each frame follows the undu-
lations formed by the aforesaid notches or grooves designed to receive the plates.
The number of the notches or grooves made in the frame and of the corresponding
notches made in the table is such that the space between two consecutive notches
or grooves corresponds with the smallest size of piece required by the consumer;
and, by dispensing successively with the partitions, multiples of this size can be
obtained to the extent determined by the dimensions of the apparatus. It will thus
be seen that, by a simple variation of the space between the partitions, pieces of
different dimensions can be obtained according to the requirements of the consumer.
The thickness of the table can also be varied, and is determined by the dimensions
of the pieces to be produced. The frame and the plate or table are, in some cases,
made of different materials and the plate or table is fixed by screws or other
'suitable mearis upon one of the faces of the frame.
The pieces of sugar are taken from the moulds in the following manner, that is to
sayWhen it is desired to remove one of the tables from the apparatus in order
to withdraw the sugar, the pieces and the movable plates or partitions are held
between the two sides of the frame; the withdrawal must be commenced by lifting
out one of the said plates or partitions, which frequently causes the breakage of one
of the adjacent pieces. I avoid this inconvenience by inserting, between one of the
vertical sides of the frame and the adjacent piece, two movable plates of trapezoidal
section. One of these plates, being inclined upon two of its faces, acts as a wedge.
The frame may be made of metal or of wood; in the latter case it is lined
internally upon the vertical sides by-fixed plates, one of which is in contact with
the sugar and is of rectangular form, and the other is of trapezoidal form-and-is in
contact with the said wedge-shaped plate.
The extraction from the moulds is commenced by lifting out the said wedge-
shaped plate which is not in contact with the sugar and which slides between the
trapezoidal plate next to it and the frame, thus leaving a space which permits the
extraction of the pieces from the moulds by causing a slight lateral displacement of
the plates and pieces, that is to say, a sliding of the same upon the bottom plate of
the table; this sliding movement separates the plates and pieces from one another
and permits them to be removed successively without any breakage of the pieces.
The plates or partitions can therefore be made rectangular.
The channel which serves for draining the syrup is a gutter formed in the top
of the horizontal part of the frame and covered with a strip of wire gauze or per-
forated sheet metal; the said gutter opens into a channel or gutter at each side of
the frame for the purpose of facilitating the cleaning of this part of the apparatus ;
it opens into holes bored slightly downwards through the sides of the frame; when
the tables are all arranged and secured one against another, the said holes form
common channels for draining the syrup, which channels can be placed in commu-
nication with machines or apparatus for creating a vacuum.
With this apparatus
the operations can be effected either with or without a cover.

"
HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings, London, IMPROVEMENTS IN APPARATUS FOR THE
MANUFACTURE OF SUGAR IN LUMPS, PIECES, OR BLOCKS"-A communication to
me from abroad by La Société Lebaudy frères, of Paris, France,
This invention relates to improvements in the apparatus for the manufacture of
Bugar in lumps, pieces, or blocks, described in the specification of former Letters
Patent dated 4th March A.D. 1882, N° 1055.
The present improvements relate more particularly to the following points, that
is to say-First, the mode of manufacturing the plates or tables of the apparatus,
based chiefly upon the employment of movable partitions or blades independent of
the metal plates which forin the bottom of the said tables; these blades are capable
of being fixed, in the frames which contain them, at different distances from one
another according to the thickness it is desired to give to the pieces of sugar.
Second, the removal of the pieces from the moulds, based upon the employment, at
the extremities of each frame of the apparatus, of a peculiar arrangement of
border or edge plates, combined with the use of plates of trapezoidal section which
facilitate the loosening of the mass and the extraction of the blades and of the
pieces of sugar contained in the apparatus. Third, the evacuation of the syrup
draining from the pieces of sugar, by means of apertures formed transversely in
each frame below the wire gauze or perforated sheet metal in the lower part of the
apparatus; the juxtaposition of these apertures, when the frames are placed
together, constituting draining channels leading to the two opposite faces of the
apparatus and placed in communication with an apparatus for creating a vacuum.
The mode of constructing the improved apparatus will be readily understood on
referring to the accompanying drawing.
As above described I make the transverse partitions of the tables or plates of
metal blades C independent of the plate which forms the bottom of the table;
these movable partitions are of a width equal to the distance between the tables
or plates and are each retained in position at the lower part by a notch or groove
formed in the frame B and at the top by a spur or projection entering a recess or
notch made in the plate which forms the bottom of the table. The wire gauze or
perforated sheet metal in the lower part of each frame follows the undulations
formed by the aforesaid notches or grooves designed to receive the lower ends of
the blades. The number of the notches or grooves made in the frame and that of
the corresponding recesses or notches made in the said plate are such that the
space between two consecutive notches or grooves corresponds in size with the
smallest piece required, and, by removing one blade, I can obtain multiples of this
size only limited by the dimensions of the apparatus. It will thus be seen that,
by a simple variation of the space between the blades and with the same apparatus,
pieces of different dimensions may be obtained according to the requirements of
the consumer. The thickness of the table or plate may also be varied and is
determined by the dimensions of the pieces to be produced. The frame and the
plate are made of different material and the plate is fixed by screws or other
suitable means upon one of the faces of the frame.
The pieces of sugar are taken from the moulds in the following manner, that is to
sayWhen one of the tables or trays is removed from the apparatus in order to
withdraw the sugar, the pieces and the movable blades C are held between the

page_text: '
two vertical sides of the frame B; the withdrawal must be commenced by lifting out
one of the pieces or one of the blades which frequently causes the breakage of one of
the adjacent pieces. This inconvenience is avoided by inserting, between one of
the vertical sides of the frame B and the adjacent piece, two movable plates R and S
of trapezoidal transverse section the plate R being inclined upon two of its
faces acts as a wedge.
.
If the frame is made of wood, it is lined internally upon the vertical sides by
fixed plates T, T', one of which T' is in contact with the sugar and is of rectangular
transverse section and the other is of trapezoidal transverse section and is in
contact with the wedge-shaped plate R.
The withdrawal of the pieces from the moulds is commenced by lifting out the
plate R which is not in contact with the sugar and which slides between the
plate S and the frame B, and plate T, thus leaving a space which permits the
extraction of the pieces from the moulds by causing a slight lateral displacement of
the plates and pieces, that is to say, a sliding of the same upon the plate A; this
sliding movement separates the blades and pieces from one another and permits
them to be removed successively without any breakage of the pieces. These
blades C are therefor made rectangular.
The channel which serves for draining the syrup is a gutter formed in the top of
the horizontal part of the frame B and covered with a strip of wire gauze or
perforated sheet metal; the said gutter has outlets at each side of the frame for
the purpose of facilitating the cleaning of this part of the apparatus; it opens into
holes bored slightly downwards through the wide side of the frame; when all the
tables or trays are arranged and secured one against another the said holes form
common channels for draining the residue, which channels can be placed in com-
munication with machines or apparatus for creating a vacuum. With this
apparatus the operations can be effected either with or without a lid or cover.
Having thus fully described the said invention as communicated to me by my
foreign correspondents and the manner of performing the same I wish it understood
that I claim.
The above described improvements in apparatus for the manufacture of sugar in
lumps, pieces or blocks, the said-improvements bearing more particularly on the
following points, that is to say:-
First. The arrangement of the tables or trays of the apparatus as above described
and shown in the accompanying drawing, consisting in the employment of a frame
of wood or metal closed on one of its faces by a smooth metal plate in front of
which movable and independent partitions or blades are fitted and held at the
lower part by notches cut in the frame and at the top by projections entering
corresponding recesses or notches made in the said plate, all substantially as, and
for the purposes, set forth.
Second The formation of notches in the frame and corresponding recesses or
notches in the plates at distances equal to the thickness of the smallest bars or
pieces required, to permit the thickness of the bars or pieces produced to be varied
according to the space allowed between the blades, the thickness of the table or
tray being also varied and determined according to the size of the pieces required,
all substantially as set forth.
Third The arrangement of the apparatus for the removal of the pieces from the
moulds by the application of border or edge plates at both ends of the frame
arranged to receive another plate of trapezoidal transverse section which can be
easily removed, before the sugar is taken out of the mould, thereby loosening the
mass and permitting the successive withdrawal of the plates and the pieces of sugar
without breakage of the latter, substantially as set forth.
Fourth-The devices for ensuring the drainage of the syrups, consisting in the
arrangement upon the lower undulations of the frame, formed by the notches in
which the movable blades fit, of a wire gauze or perforated sheet metal plate
beneath which a gutter is made terminating at each end of the frame, to permit
the cleansing of this part of the apparatus, a number of transverse apertures being

page_text: formed in the lower part of the frame, which apertures by their juxtaposition when
the tables or trays are assembled form common channels leading to the conduits
arranged in the end plates of the frame of the apparatus and which are put in
communication with an apparatus for creating a vacuum in order to drain off the
refuse, substantially as set forth.
In witness whereof I the said Henry Harris Lake have hereunto set my
hand and seal this seventeenth day of May in the year of our Lord One
thousand eight hundred and eighty three.
HENRY H. LAKE (LS.)
