IMPROVEMENTS IN MOULDING SUGAR
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
GYE, of South Lambeth, in the County of Surrey, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twentieth day of November, in the ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Frederick Gye, my exors, admors, and assigns, Her especial licence, full power,
sole privilege and authority, that I, the said Frederick Gye, my exors, admors,
and assigns, or such others as I, the said Frederick Gye, my exors, admors, or
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, and in the Islands of Jersey, Guernsey, Alderney,
Sark, and Man, and also in all Her said Majesty's Colonies and Plantations
abroad, the Invention of "IMPROVEMENTS IN MOULDING SUGAR," communicated
to me from abroad; in which said Letters Patent is contained a proviso, that I,
the said Frederick Gye, shall cause a particular description of the nature of
the said Invention, and in what manner the same is to be performed, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Frederick Gye, do hereby declare that the nature of the said Invention,
and the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference, being had
to the Drawing hereunto annexed, and to the figures and letters marked
thereon, that is to say :-
In the manufacture of refined sugar it has heretofore been usual to shape
the same into what are called loaves, by pouring the granulated sugar into
earthenware or metal moulds of a conical shape. The refined sugar thus
obtained in loaves is chopped up for use, by which not only is there consider-
able labour employed, but much waste takes place. Now this Invention
consists of using pressure in moulds, so as to compress or shape sugar into the
forms desired for use; and in order that the Invention may be most fully
understood, and readily carried into effect, I will proceed to describe the means
pursued by me.
"
In carrying out the Invention, I make no difference in the practice of refining
sugar, and conical moulds are used by me, and the treatment of the sugar
therein is not altered; and the loaves being taken out of the moulds, the
process is to be carried on in the usual manner up to the time of getting the
sugar nearly dry, and so that it may be crushed by the workman simply
pressing with a board. The sugar being broken down or crushed, a small
quantity of water in minute streams is to be applied, in order that the sugar
may be in a slightly moist state when it is submitted to pressure in moulds,
in order to compress and shape the sugar into forms and of a size suitable for
use. I employ for this purpose a screw press, but other arrangements of
presses may be applied for this purpose.
The Drawing shows a perspective view of the press and moulds used by me.
a, a, is the framing of the press, the nature of which is clearly shown by the
Drawing. is a quadrangular frame of moulds suitably arranged for com-
pressing and moulding sugar into cubes, but moulds for making other shapes
may, if desired, be resorted to. The frame of moulds is supported in the
frame by means of projecting ribs a', a', as shown. c is a board, which I
prefer to be of oak, at the bottom of the moulds, and d is an iron plate for
upholding the board, which slides in grooves a² in the framing. The moulds b
are to be filled with sugar in a granulated and moist state. The frame of
plungers e is then brought down by turning the screw, and thus is pressure
exerted in each of the compartments or moulds of the frame b, 'so as to com-
press the sugar, and I make the moulds three times as deep as they measure
across, and the pressure offered brings the moulded sugar into one third of the

page_text: depth of the moulds, thus producing cubes of sugar. The plungers e are then
raised by the screw. The plate d is removed, and the board c is allowed to
descend slowly, by which the compressed and moulded sugar will come out of
the moulds and descend with the board, and in this state the sugar is to be
placed in a stove such as is now used for drying sugar. By this means sugar
may be prepared of such figures or shapes and of such sizes as may be desired
for use, depending on the shapes and sizes of the moulds employed for carrying
out the Invention.
Having thus described the nature of the improvements, and the manner of
performing the same, I would have it understood that I do not claim any
parts of the machinery, nor do I confine myself to the details as shown and
described; but what I claim is, the shaping of sugar into suitable forms for
use by compressing the same in moulds, as above described.
In witness whereof, I, the said Frederick Gye, have hereunto set my
hand and seal, this Twentieth day of May, in the year of our Lord
depth of the moulds, thus producing cubes of sugar. The plungers e are then
raised by the screw. The plate d is removed, and the board c is allowed to
descend slowly, by which the compressed and moulded sugar will come out of
the moulds and descend with the board, and in this state the sugar is to be
placed in a stove such as is now used for drying sugar. By this means sugar
may be prepared of such figures or shapes and of such sizes as may be desired
for use, depending on the shapes and sizes of the moulds employed for carrying
out the Invention.
Having thus described the nature of the improvements, and the manner of
performing the same, I would have it understood that I do not claim any
parts of the machinery, nor do I confine myself to the details as shown and
described; but what I claim is, the shaping of sugar into suitable forms for
use by compressing the same in moulds, as above described.
In witness whereof, I, the said Frederick Gye, have hereunto set my
hand and seal, this Twentieth day of May, in the year of our Lord
One thousand eight hundred and forty-six.
FRED GYE, J. (L.E.)
AND BE IT REMEMBERED, that on the Twentieth day of May, in the
year of our Lord 1846, the aforesaid Frederick Gye came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification aforesaid,
and all and every thing therein contained and specified, in form above written.
