page_text: LETTERS PATENT to William Garton, of the Town and County of
Southampton, Brewer, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF SUGAR FOR BREWING AND OTHER PURPOSES.”.
MANUFACTURE OF SUGAR FOR BREWING AND OTHER PURPOSES.'
Sealed the 16th February 1875, and dated the 17th November 1874.
PROVISIONAL SPECIFICATION left by the said William Garton at the
Office of the Commissioners of Patents, with his Petition, on the
17th November 1874.
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 MANUFACTURE OF SUGAR FOR BREWING AND OTHER PURPOSES,"
to be as follows:-
My Invention has reference to the manufacture of sugar composed
partly of dextro-glucose obtained from rice or other amylaceous sub-
stances, and partly of lovo-glucose obtained from cane, beet, or other
like sugar producing substances or their products.
n
Dextro-glucose and loevo-glucose are two separate and distinct manu-
£heminm it kon heon found honeficial to

page_text: mix some of the dextro-glucose obtained as aforesaid from amylaceous
substances with the lovo-glucose obtained from cane or beet.
In converting amylaceous substances into dextro-glucose by means of
an acid and heat in the ordinary way such conversion ceases as soon as
the solution has attained a specific gravity of from 1·070 to 1·080, any
further quantity of the amylaceous substance which is added after
this limit has been reached simply remaining in the form of starch.
It has therefore been usual to neutralize the solution with chalk or other
suitable material as soon as the conversion can be no longer carried on,
and in consequence of the very low specific gravity great expense in
fuel has been necessary for evaporating the water in the subsequent
process of concentration. On the other hand, in treating cane, beet, or
such like crystallized sugar so as to obtain loevo-glucoso an inversion
may be effected in solutions of specific gravities of even 1.200 to
1.275.
Now the object of my Invention is to effect economy in the manufac-
ture of this combined article by the processes herein-after described,.
whereby the acid usually employed in converting the amylaceous sub-
stances is saved, as well as a considerable amount of the fuel required
for heating the solutions to the necessary temperatures and for their
concentration, and I am also able to effect the admixture of the dextro-
glucose and the loevo-glucose in the process of conversion and to
neutralize the acid employed for both at one operation. For this purpose
I place the rice or amylaceous substance in a suitable vessel previously
charged with boiling acid water, and keep adding more rice and more
acid until the mixture has reached the point of about 1.075, and I
maintain the heat so long as any traces of starch can be detected, i. e.,
until the conversion of the solution. is complete. Then instead of
neutralizing the mixture in the usual way at this stage I take advantage
of the fact, which I have ascertained by experiment, viz., that the acid
employed in converting is further capable of inverting large proportions
of crystallized sugar while the glucose obtained from: the rice still.
remains in the solution. I therefore add sufficient cane or beet sugar to
increase the gravity of the solution to about 1.275, and when the
inversion is complete I neutralize by the usual means, and at one and
the same time, the acid solution containing both the dextro-glucose from
the rice and the loevo-glucose from the sugar. I thus utilize the acid
which has been employed in the conversion of the rice for the inversion

page_text: of the sugar, and as the sugar is placed in a solution which has been
maintained at a sufficient heat for the conversion of the rice I save the
fuel which is necessary for heating when the sugar is treated separately.
I also dispense with the chalk or lime usually required for neutralizing,
and further save the large quantity of fuel that would have been
necessary for concentrating the solution of dextro-glucose from 1.075 to
1.275 had it been manufactured separately.
By the means herein-before described I obtain an article composed of
about 20 per cent. of dextro and 80 per cent. of loevo sugar specially
adapted for brewing, and which may also be employed for wine and
vinegar making and for other purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said William Garton in the Great Seal Patent Office on
the 15th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GARTON, of the Town and County of Southampton, Brewer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of November, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said William Garton, Her
special licence that I; the said William Garton, my executors, admini-
strators, and assigns, or such others as I, the said William Garton, 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 "IMPROVE
MENTS IN THE MANUFACTURE OF SUGAR FOR BREWING AND OTHER PURPOSES,"
upon the condition (amongst others) that I, the said Willam Garton,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and scals, should particularly
describe and ascertain the nature of the said Invention, and in what
-

page_text: 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 :-
My Invention has reference to the manufacture of sugar composed
partly of dextro-glucose obtained from rice or other amylaceous sub-
stances, and partly of loevo-glucose obtained from cane, beet, or other
like sugar producing substances or their products.
Dextro-glucose and loevo-glucose are two separate and distinct manu-
factures, but for the purposes of brewing it has been found beneficial to
mix some of the dextro-glucose obtained as aforesaid from amylaceous.
substances with the loevo-glucose obtained from cane or beet..
In converting amylaceous substances into dextro-glucose by means of
an acid and heat in the ordinary way such conversion ceases as soon as
the solution has attained a specific gravity of from 1.070 to 1.080, any
further quantity of the amylaceous substance which is added after this
limit has been reached simply remaining in the form of starch. It has
therefore been usual to neutralize the solution with chalk or other
suitable material as soon as the conversion can be no longer carried on,
and in consequence of the very low specific gravity great expense in
fuel has been necessary for evaporating the water in the subsequent
process of concentration. On the other hand, in treating cane, beet, or
such like crystallized sugar so as to obtain lœvo-glucose an inversion
may be effected in solutions of specific gravities of even 1.200 to
1.275.
Now the object of my Invention is to effect economy in the manu-
facture of this combined article by the processes herein-after described,
whereby the acid usually employed in converting the amylaceous sub-
stances is saved, as well as a considerable amount of the fuel required
for heating the solutions to the necessary temperatures and for their
concentration, and I am also able to effect the admixture of the dextro-
glucose and the Icevo-glucose in the process of conversion, and to
neutralize the acid employed for both at one operation. For this purpose
I place the rice or amylaceous substance in' a suitable vessel previously

page_text: charged with boiling acid water, and keep adding more rice and more
acid until the mixture has reached the point of about 1.075, and I main-
tain the heat so long as any traces of starch can be detected, i. e., until
the conversion of the solution is complete. Then instead of neutralizing
the mixture in the usual way at this stage I take advantage of the fact,
which I have ascertained by experiment, viz., that the acid employed in
converting is further capable of inverting large proportions of crystallized
sugar, while the glucose obtained from the rice still remains in the
solution. I therefore add sufficient cane or beet sugar to increase the
gravity of the solution to about 1.275, and when the inversion is complete
I neutralize by the usual means, and at one and the same time, the acid
solution containing both the dextro-glucose from the rice and the loevo-
glucose from the sugar. I thus utilize the acid which has been employed
in the conversion of the rice for the inversion of the sugar, and as the
sugar is placed in a solution which has been maintained at a sufficient
heat for the conversion of the rice I save the fuel which is necessary for
heating when the sugar is treated separately. I also dispense with the
chalk or lime usually required for neutralizing the dextro-glucose, and
further save the large quantity of fuel that would have been necessary
for concentrating the solution of dextro-glucose from 1.075 to 1.275 had
it been manufactured separately.
By the means herein-before described I obtain an article composed of
about 20 per cent. of dextro and 80 per cent. of loevo sugar (which
proportions may however be varied according to requirement) specially
adapted for brewing, and which may also be employed for wine and
vinegar making and for other purposes.
In witness whereof, I, the said William Garton, have hereunto set
my hand and seal, this Fourteenth day of May, One thousand
