page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical Draughts-
man, for the Invention of "IMPROVEMENTS IN EVAPORATING APPARATUS
APPLICABLE TO THE MANUFACTURE OF SUGAR."-A communication from
abroad by Théodore Champierre de Villeneuve, of Rue St. Sebastien,
Paris, in the Empire of France.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 11th October 1862.
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 EVAPORATING APPARATUS
APPLICABLE TO THE MANUFACTURE OF SUGAR," to be as follows:-
This Invention relates to improvements in the construction of evaporating
pans or boilers, their chief use being the evaporation or boiling of syrup in
the manufacture of sugar. The object is to increase the heating surface of
such pans, and thereby to economise fuel, and expedite the operation of
evaporation or boiling; this is effected by constructing the bottoms of the

page_text: pans or boilers of a corrugated or wavy form, the corrugations forming
deep channels for the passage forwards of the flame and heated gases of the
furnace.
The boiling vessels may be arranged in the ordinary manner employed in
the colonies, that is to say, the apparatus may consist of nine pans or boilers
set in a row, and heated by a single furnace at one end, a flue underneath
them serving to convey the heat to the whole series. The first pan or boiler
will, by preference, be made plain, but the eight following ones will be cor-
rugated or wavy, as above-mentioned; the depth of the corrugations may
vary according to the will of the constructor. The five boilers in the middle
of the apparatus will be separated by partitions somewhat lower than those
of the others; the whole series are to be set in masonry so as to present a
raised rim at each side, and seven boilers set nearest the furnace will be so
fixed in conjunction with two outside rims of greater elevation, which together
constitute two troughs or channels at the sides of the boilers for the reception
of any syrup which may overflow or boil over.
may overflow or boil over. The boilers may be made to
communicate by means of valves for. the purpose of facilitating the operation,
which is carried on in this apparatus in the ordinary manner.
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 11th April 1863.
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 Eleventh day of October, in the year of our Lord
One thousand eight hundred and sixty-two, in, the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Alfred Vincent Newton, Her special license, 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

page_text: Invention for "IMPROVEMENTS IN EVAPORATING APPARATUS APPLICABLE TO THE
MANUFACTURE OF SUGAR," being a communication from abroad, upon the con-
dition (amongst others) that I, the said Alfred Vincent Newton, by an
instrument in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention, as communicated to me by my foreign correspondent,
relates to improvements in the construction of evaporating pans or boilers,
their chief use being the evaporation or boiling of syrup in the manufacture
of sugar. By these improvements the heating surface, and consequently
the evaporating capacity of the pans or boilers, is materially increased without
increasing the dimension of the apparatus, and the loss of syrup occasioned
by overflows is avoided.
In constructing evaporating apparatus according to this Invention, the
bottoms of the pans or boilers are made with corrugations sufficiently deep to
form flues running longitudinally of the boiler for the passage forwards of the
flame and heated gases of the furnace, and between these flues channels for
the circulation of the liquid under treatment.
The boiling vessels may be arranged in the ordinary manner employed in
the colonies, that is to say, the apparatus may consist of nine pans or boilers
set in a row, and heated by a single furnace at one end, a brick flue under-
neath them serving to convey the heat to the whole scries. The first pan or
boiler will, by preference, be made plain or with a flat bottom, but the eight
following ones will be corrugated or wavy, as above mentioned. The depth of
the corrugations may vary according to the will of the constructor, so long as
their efficiency in respect of producing an appreciable increased heating surface
is not materially interfered with. The five boilers in the middle of the
apparatus will be separated by partitions somewhat lower than those of the
others. The whole series are to be set in brickwork or masonry so as to
present a raised rim at each side, and the seven boilers set, nearest the fire-
place are to be fixed in conjunction with two outside rims of greater elevation,

page_text: which together constitute two troughs or channels at the sides of the boilers
for the reception of any syrup which may overflow or boil over.
The pans or
boilers may be made to communicate by means of valves for the purpose of
facilitating the operation which is carried on in this apparatus in the ordinary
manner.
In the accompanying Drawing Fig. is a longitudinal vertical section,
shewing the furnace or fire-place end of the apparatus; Fig. 2 is a transverse
section of the same taken in the line 1, 2, of Fig. 1; Fig. 3 is another trans-
verse section taken in the line 3, 4, of Fig. 1; and Fig. 4 shews on a reduced
scale the whole of the apparatus in outside view. On referring to these
figures it will be seen that the pans or boilers are arranged so as to work in
the same manner as the apparatus employed in the colonies, with an open
fire, that is to say, they are heated by the flame and heated gases generated
in a single fire-place A; this fire-place is fed with straw or exhausted sugar
cane, and the ashes falling through the grate bars are removed from the ash-
pit through a door B provided for the purpose. The first pan or boiler C, it
will be seen, is not corrugated, but the eight following ones D are provided
with corrugated bottoms D', the corrugations of which may be of greater or
less depth. The five middle pans or boilers are merely separated by a
partition of less height than those of the
whole of them are set in the masonry or
present on each side a slight projection E running the whole length of the
seven boilers placed nearest the fire-place of the furnace; these projections
constitute, together with the rims F which run parallel with the sides of the
pans, two troughs which return the overflow liquid to the boilers. By this
means the waste ordinarily occasioned by the overflow of the syrup during the
boiling process is avoided. The pans, by being brought into communication
with each other by means of valves S, facilitate the operation of supplying
them with syrup.
other boilers (see Fig. 4), and the
brickwork of the furnace so as to
Fig. 5 shews, in transverse section, a pan or boiler which is made wider at
the top than at the bottom, but which is otherwise constructed like those
above described, with a corrugated bottom, and furnished with the projecting
rims F at top forming troughs at opposite sides thereof. This apparatus is
worked in exactly the same manner as that ordinarily employed for the
purpose.
Having now set forth the nature of the Invention of "Improvements in
Evaporating Apparatus applicable to the Manufacture of Sugar," and explained
the manner of carrying the same into effect, I wish it to be understood that,

page_text: under the above in part recited Letters Patent, I claim constructing evapo-
rating apparatus in the the manner above described, whereby the operation of
concentrating syrups and other fluids may be more economically effected than
by the evaporating pans ordinarily used for tho
purpose.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, this Eleventh day of April, in the year of our
Lord One thousand eight hundred and sixty-three.
