IMPROVEMENTS IN THE PREPARATION OF FERMENTABLE SACCHARINE MATTERS."
Year: 1870

page_text: LETTERS PATENT to William Garton, of the Town and County of
Southampton, Brewer, for the Invention of "IMPROVEMENTS IN THE
PREPARATION OF FERMENTABLE SACCHARINE MATTERS."
PROVISIONAL SPECIFICATION left by the said William Garton at the
Office of the Commissioners of Patents, with his Petition, on the
22nd January 1870.
I, WILLIAM GARTON, of the Town and County of Southampton,
Brewer, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN THE PREPARATION OF FERMENTABLE SACCHARINE MATTERS," to be
as follows:
The Invention relates to the treatment of sugar and other saccharine
matters to be used for the purpose of preparing fermented liquors. In
preparing saccharine matters, whether from sugar or from amylaceous
substances, it is usual to treat the sugar or other substance with an acid
in order to convert it into lævo-glucose or dextro-glucose, which is more
suitable for the purpose of fermentation, and after this conversion it
;

page_text: is usual to neutralize the acid with chalk, lime, or other suitable
substance.
My Invention refers to that stage of the process in which acid is
pressed in the saccharine solution in a free state, and consists in adding
to the solution either during the conversion or after the conversion is
completed some anímal charcoal or other substance containing phosphate
of lime; the effect of this addition is that the free acid acts upon the
charcoal and renders the phosphates therein soluble so that when the
acid is neutralized these phosphates are reprecipitated in a finely
dívided condition, and when the precipitate subsides or the solution is
filtered a better defecation or purification of the saccharine matters is
produced. Or I put the animal charcoal or other substance containing
phosphate of lime with the sugar before adding the acid; or I mix the
charcoal with the acid before adding the acid to the șugar.
Without limiting myself to any particular proportions I may state that
as far as my present experience goes I consider from 2 to 10 per cent.
of phosphate of lime in proportion to the sugar will answer well, the
amount of phosphate varying according to the quantity of acid employed
and other circumstances.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Garton in the Great Seal Patent Office
on the 22nd July 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GARTON, of the Town and County of Southampton, Brewer, send

page_text: 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
PREPARATION OF FERMENTABLE SACCHARINE MATTERS," upon the condition
(amongst others) that I, the said William. Garton, 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 William Garton, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
The Invention relates to the treatment of sugar and other saccharine
matters to be used for the purpose of preparing fermentable liquors. In
preparing saccharine matters, whether from sugar or from amylaceous
substances, it is usual to treat the sugar or other substance with an acid
in order to convert it into lævo-glucose or dextro-glucose, which is
more suitable for the purpose of fermentation, and after this conversion
it is usual to neutralize the acid with chalk, lime, or other suitable
substance.
My Invention refers to that stage of the process in which acid is
present in the saccharine solution in a free state, and consists in adding
to the solution, either during the conversion or after the conversion is
completed, some animal charcoal or other substance containing phosphate
of lime; the effect of this addition is that the free acid acts upon the
charcoal and renders the phosphates therein soluble, so that when the
acid is neutralized these phosphates are reprecipitated in a finely
divided condition, and when the precipitate subsides or the solution is
filtered a better defecation or purification of the saccharine matters is
produced.
Without limiting myself to any particular proportions I may state
that as far as my present experience goes. I consider from 2 to 10 per
cent. of phosphate of lime in proportion to the sugar will answer well, the

page_text: amount of phosphate varying according to the quantity of acid employed
and other circumstances.
In witness whercof, I, the said William Garton, have hereunto set
my hand and seal, this Nineteenth day of July One thousand
eight hundred and seventy.
