IMPROVEMENTS IN HEATING AND CLARIFYING SACCHARINE FLUIDS
Year: 1862

page_text: LETTERS PATENT to Richard Wright, of 18, Albany Road, Camberwell,
in the County of Surrey, for the Invention of "IMPROVEMENTS IN HEATING
AND CLARIFYING SACCHARINE FLUIDS."
Scaled the 29th August 1862, and dated the 7th March 1862.
PROVISIONAL SPECIFICATION left by the said Richard Wright at the
Office of the Commissioners of Patents, with his Petition, on the 7th
March 1862.
I, RICHARD WRIGHT, of 18, Albany Road, Camberwell, in the County, of
Surrey, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
HEATING AND CLARIFYING SACCHARINE FLUIDS," to be as follows:-
This Invention has for its object improvements in heating and clarifying
saccharine fluids. In heating saccharine fluids, as heretofore practised when
clarifying such fluids, the heat has not been so applied as to ensure the best
results.
Now my improvements consist in carrying on the heating and clarifying
process in vessels or apparatus such as are described in the Specification of a
former Patent granted to me, dated 6th September 1860, No. 2153, for
evaporating saccharine fluids in the manufacture and refining of sugar; but when
heating and clarifying saccharine fluids according to my present Invention,
the revolving discs or surfaces described in such former Specification are not
used, the clarifying process not requiring evaporation or motion of the fluid as

page_text: when manufacturing or refining sugar, as described in such former Specification.
By these means of carrying on the process of heating and clarifying saccharine
fluids, the bottom of the pan or vessel containing the saccharine fluid is heated
by the vapour of boiling water, which is in a vessel below, at the same time
the water in this vessel is prevented from coming in contact with the bottom
of the pan or vessel containing the saccharine fluid, and is also prevented from
rising in temperature above 212° Fahrenheit, by reason of the vessel containing
it being constantly open to the atmosphere.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Wright in the Great Seal Patent Office on the 6th
September 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
WRIGHT, of 18, Albany Road, Camberwell, in the County of Surrey, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of March, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Richard Wright, Her special licence, that I, the said Richard Wright, my
executors, administrators, and assigns, or such others as I, the said Richard
Wright, my executors, administrators, and assigns, should at any time agree
with, and no others, and no others, from time to time and at all times there-
after 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
HEATING AND CLARIFYING SACCHARINE FLUIDS," upon the condition (amongst
others) that I, the said Richard Wright, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, 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 Richard Wright, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in heating and clarifying

page_text: saccharine fluids. In heating saccharine fluids as heretofore practised when
clarifying such fluids, the heat has not been so applied as to ensure the best
results.
Now my improvements consist in carrying on the heating and clarifying
process in vessels or apparatus, such as are described in the Specification of a
former Patent granted to me, dated 6th September 1860, (No. 2153,) for
evaporating saccharine fluids in the manufacture and refining of sugar; but
when heating and clarifying saccharine fluids according to my present Invention
the revolving discs or surfaces described in such former Specification are not
used, the clarifying process not requiring, evaporation or motion of the fluid
as when manufacturing or refining sugar, as described in such former
Specification. By these means of carrying on the process of heating and
clarifying saccharine fluids, the bottom of the pan or vessel containing the
saccharine fluid is heated by the vapour of boiling water, which is in a vessel
below at the same time the water in this vessel is prevented from coming in
contact with the bottom of the pan or vessel containing the saccharine fluid;
and is also prevented from rising in temperature above 212° Fahrenheit by
reason of the vessel containing it being constantly open to the atmosphere.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
The Drawing represents a section of the vessel used by me for the purpose
of carrying out my Invention; this vessel is similar in construction to that
used by me in combination with a series of discs for the evaporating syrups or
saccharine liquids in the refining and manufacture of sugar. In the heating
of saccharine fluids for the purpose of clarifying them, as little evaporation of
the fluids as possible should take place, and the process of heating and
clarifying is, according to my present Invention, effected in the vessel shewn
in the Drawing without the employment of the rotating discs or apparatus
formerly used by me for giving motion to, and for raising thin films of such
fluids out of the body of fluid.
A is the vessel in which the saccharine fluid is placed to be heated and
clarified. This vessel is, by preference, to be semicircular in section, though
other forms may be resorted to when carrying out my Invention, and they may
be of any desired length. The vessel A is set in another vessel B, in such
manner as to allow space below it for the reception of water the level of which
is not to be allowed to rise so high in the vessel 13 as to touch the bottom of
the vessel A, on the contrary, there is a space between the water in the vessel B

page_text: and the bottom of the vessel A, and the level of the water in the vessel B is
insured by an overflow pipe C. In order that the water in the vessel B may
not rise above 212° Fahrenheit, a pipe or opening D is employed which is at
all times open to the outer atmosphere. The water in the vessel B is heated
by means of steam pipes or otherwise, the saccharine liquids are drawn off
from the vessel A by means of a cock at.E. The peculiarity of this Invention
consists in clarifying saccbarine fluids by heating them in vessels which are
heated by the vapour of water in the manuer herein described.
In witness whereof, I, the said Richard Wright, have hereunto set my
hand and seal, this Twenty-fifth day of August, in the year of our Lord
One thousand eight hundred and sixty-two.
RICHARD WRIGHT. (L.S.)
