page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lanc, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVEMENTS IN THE MODE
OF AND APPARatus for FilliNG SUGAR MOULDS AND TREATING SUGAR IN THE
MOULDS."—A communication from abroad by Franz O. Matthiessen,
of New York City, United States of America.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent
Newton at the Office of the Commissioners of Patents, with his
Petition, on the 20th April 1875.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MODE OF AND APPARATUS FOR FILLING SUGAR MOULDS AND TREATING SUGAR
IN THE MOULDS," to be as follows:-
This Invention relates to the arrangement upon a liquoring or
cleansing table of suitable apparatus for holding a series of moulds of

page_text: such construction and in such position that they can all be filled with
the sugar mass at one operation, and when filled the sugar contained in
them can be liquored or freed from green syrup at one operation and
with improved effect.
Upon the liquoring table is fixed a vertical clamping frame for
containing a series of sugar moulds. The sides of this frame form guides
for preserving the allinement of the moulds which are placed therein one
above the other, and are held tightly together in the frame by a pressure
screw or its equivalent. The moulds are made with inclined sides and
parallel ends, which latter are grooved to fit the guides. These moulds
are open both at top and bottom and they are piled one upon another to
any given height, elastic packing strips being placed between them to
ensure a tight joint. Upon the uppermost mould is fitted what may
be termed a surplus mould which constitutes at once a hopper and a
funnel for receiving the sugar mass and supplying it to the moulds.
This hopper is fitted with a cross bar on which the pressing screw of the
cross head of the frame bears. By turning therefore this screw the
moulds will be tightly clamped in the frame. The face of the liquoring
table upon which the pile of moulds is set up has a concave recess
immediately below the moulds, and in communication therewith is an
injection nozzle connected by a pipe with the vacuum pan. This
concave recess is furnished at bottom with a cylindrical or other channel
which is closed up by a removable plug, but which is pierced with holes
upon its upper
side to put it in communication with the concave recess.
The object of this channel is to discharge cleansing liquor into the
moulds when the sugar mass has crystalized therein.
When employing the above described apparatus the sugar mass may
be injected into the series of moulds from below or poured in from above.
Care must however be taken that the supply is in excess of the capacity
of the moulds, so as to ensure the complete filling from the hopper of the
uppermost mould as the syrup is separated from the crystals and the
crystals settle down.
When the crystallization is effected streams of cleansing liquor are
forced up through the moulds, and the green syrup is thereby discharged
therefrom.
I may remark that the moulds may be put together in pairs, the

page_text: corresponding parts of the adjacent mould. This involves the inverting of
every other mould; but in place of this arrangement they may be placed
one above the other and supported by an intervening perforated plate.
An important advantage attending the use of the above described
process is that the boiling operation in the vacuum pan may be prolonged.
until the sugar mass contains an unusually large proportion of
orstallizable material
corresponding parts of the adjacent mould. This involves the inverting of
every other mould; but in place of this arrangement they may be placed
one above the other and supported by an intervening perforated plate.
An important advantage attending the use of the above described
process is that the boiling operation in the vacuum pan may be prolonged,
until the sugar mass contains an unusually large proportion of
crystallizable material
When the liquoring operation is completed the moulds are removed
from the clamping frame, and placed in a centrifugal machine wherein
the inclined sides of the mould frames occupy radial vertical planes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 20th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Alfred Vincent Newton, Her
special licence that I, the said Alfred Vincent Newton, my executors,
administrators, and assigns, or such others as I, the said Alfred
Vincent Newton, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN THE MODE OF AND APPARATUS FOR FILLING
SUGAR LOULDS AND TREATING SUGAR IN THE MOULDS," being a communi-
cation to me from abroad by Franz O. Matthiessen, of New York City,
United States of America, upon the condition (amongst others) that I,
the said Alfred Vincent Newton, my executors or administrators, by an

page_text: shape to the mouth of the cavity a, and rests upon a strip of elastic
material a¹ which is placed on the table around the edge of the cavity a.
The next mould frame, or as it will be more convenient to call it,
mould c¹ is reversed in position so as to fit the top of the mould c, and
6 another strip of elastic material a² is introduced between the edges of
the two moulds c and c'. The moulds are alternately reversed as they
are placed one above the other, as shewn in Fig. 1, and are separated
from each other by the clastic packing strips a², a³, and a*. The upper-
most mould c³, is provided with a similar packing strip a³ upon
its upper
O edge which serves to pack the joint between the uppermost mould and the
surplus mould frame d. The latter is provided with a horizontal bar ď¹
extending from end to end, which furnishes a bearing for the screw
bolt e, by means of which the moulds are pressed firmly downward upon
the table, and upon each other so as to make tight joints by means of
5 the packing strips a', a², a³, aª, and aª.
The moulds are held in position by means of two vertical guides or
ways fand f', which are respectively bolted to the top of the liquoring
table. The inner faces of these guides respectively engage grooves in the
opposite ends of the mould frames. The upper ends of the vertical
guides and f¹ are secured to a cross bar g by means of the pins g¹
and g³. The screw bolt e passes vertically through the centre of the
cross bar g engaging a female thread therein.
It will be seen that by loosening the screw bolt e and removing the
pins g¹ and 9, the cross bar y can be detached, so that the moulds can
be slipped in or out of position upon the guides fand ƒ'.
When the moulds are in position and have been clamped down by
means of the screw bolt e, as has been described, they may be filled with
the sugar mass from the top through the surplus mould d or from the
bottom through the nozzle b.
The object of the surplus mould d is threefold,-
First. To furnish the means for transmitting the pressure of the screw
bolt e to the several moulds below it, so that tight joints may be made
between the several moulds and the table, as has been stated.
Secondly. To facilitate the introduction of the sugar mass into the
3 moulds from the top.

page_text: Thirdly. To hold an excess of the sugar mass so as to insure the
complete filling of the uppermost mould when the syrup is separated
from the crystals and the crystals settle down.
The ejection nozzle 6 will of course be connected by a pipe with the
vacuum pan which will be provided with a stop-cock to be closed when
the moulds are full.
The cleansing operation is performed by removing the plug h and
injecting the cleansing liquor into the pipe i from which it passes
through the perforations k, k, k, &c., upward through the sugar mass
contained in the moulds, carrying the green syrup into and over the
surplus frame d at the top. By this mode of cleansing sugar only one
crust is formed, and the green syrup is wholly eliminated from the sugar
contained in the moulds. Or if a large proportion of syrup be present
in the sugar mass, the lower moulds will be wholly freed from it, and
the sugar mass in the upper mould only will exhibit it.
It is an important advantage attending the use of this Invention that
the boiling in the vacuum pan may be prolonged until the sugar mass
contains an unusually large proportion of crystallized material. This
advantage arises from the fact that great facility is afforded for filling a
series of moulds and handling rapidly a large quantity of material; a
consequence of this prolonged boiling in the vacuum pan is that a less
proportion of green syrup than usual has to be driven out of the sugar
mass contained in the moulds.
When the liquoring operation is completed, the surplus frame d is
removed and the moulds are taken out and separated from each other,
and are deposited in a centrifugal machine wherein the inclined sides of
the mould frames occupy radial vertical/planes.
.
The mould frames may be arranged with reference to each other, as
shewn in Fig. 4, if desired. In such case a perforated plate p will be
introduced between the moulds, and the two packing strips & and ♪ will
be inserted between the plate and the edges of the moulds, as shown.
T
Having now set forth the nature of the Invention of "Improvements
in the Mode of and Apparatus for Filling Sugar Moulds [and Treating
Sugar in the Moulds," as communicated to me by my foreign corre-
spondent, and explained the manner of carrying the same into effect, I
wish it to be understood that under the above in part recited Letters
Patent, I claim,-

page_text: First. The arrangement of apparatus above described for moulding
sugar and liquoring the same in the moulds.
Second. The mode above described of filling a series of sugar moulds
and of liquoring the sugar in the said moulds at one operation.
In witness whereof, I, the said Alfred Vincent Newton, have
hereunto set my hand and seal, the Nineteenth day of October,
in the year of our Lord One thousand eight hundred and seventy-
five.
