page_text: LETTERS PATENT to William Maltby, of De Crespigny Park, Cam-
berwell, in the County of Surrey, for the Invention of "IMPROVEMENTS
IN THE PROCESS OF MANUFACTURING A GLUTINOUS OR VISCOUS SUBSTANCE TO
BE USED IN DRESSING TEXTILE FABRICS, AND FOR OTHER SUCH LIKE PROCESSES,
OR IN BREWING AND DISTILLING, AND ALSO IN THE APPARATUS TO BE USED FOR
THE SAME AND SIMILAR PURPOSES."
Sealed the 9th August 1861, and dated the 12th February 1861.
PROVISIONAL SPECIFICATION left by the said William Maltby at the
Office of the Commissioners of Patents, with his Petition, on the 12th
February 1861.
I, WILLIAM MALTBY, of De Crespigny Park, Camberwell, in the County
of Surrey, Gentleman, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE PROCESS OF MANUFACTURING A GLUTINOUS OR VISCOUS
SUBSTANCE TO BE USED IN DRESSING TEXTILE FABRICS, AND FOR OTHER BUCH LIKE
PROCESSES, OR IN BREWING AND DISTILLING, AND ALSO IN THE APPARATUS TO BE
USED FOR THE SAME AND SIMILAR PURPOSES," to be as follows, that is to say:-
I take ground rice, and mix it with about one-third of its weight of, pre-
ferably, warm water, at a moderate temperature. I allow it to stand for
several days, stirring it occasionally until fermentation has commenced. I then

page_text: dry it by artificial heat, which I regulate according as I require it to be more
or less glutinous. The resulting product is now ground, mixed with hot water,
and is then ready for use.
Unground or whole rice is treated by being mixed with, preferably, hot
water, the temperature not greater than 160 degrees of Fab., and kept well
stirred until the grains by slightly triturating will form a paste. I strain off
the liquor, and allow fermentation to commence. I dry the product, as before
described, grind, and mix with water; the substance is, then produced ready
for use.
The apparatus which I make use of for effecting the before-mentioned
action upon the rice or other material is as follows:-I take a cylindrical,
octagonal, or other shaped vessel, and having trunnions, or spindles, or an axis
to rotate on. The vessel is perforated throughout its whole periphery. with
holes or interstices. The rice or other material to be acted upon is intro-
duced. The whole is enclosed in a covering of perforated metal or even
canvas or other open fabric, and in this state is suspended horizontally in a
vessel of water of the temperature required, and caused to rotate upon its
axle or spindle until the operation is complete.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Maltby in the Great Seal Patent Office on the
12th August 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MALTBY, of De Crespigny Park, Camberwell, in the County of Surrey,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelth day of February, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Maltby, Her special licence that I, the said William
Maltby, my executors, administrators, and assigns, or such others as I,
the said, William Maltby, 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
nake, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for

page_text: "IMPROVEMENTS IN THE PROCESS OF MANUFACTURING A GLUTINOUS OR VISCOUS
SUBSTANCE TO BE USED IN DRESSING TEXTILE FABRICS, AND FOR OTHER SUCH LIKE
PROCESSES, OR, IN BREWING AND DISTILLING, AND ALSO IN THE APPARATUS TO BE
USED FOR THE SAME AND SIMILAR PURPOSES," upon the condition. (amongst
others). that I, the said William Maltby, 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 Inven-
tion, and in what manner the same was to be performed, and cause the
šame 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 Maltby, 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 fol-
lowing statement, that is to say :-
I take ground rice, and mix it with about one-third of its weight of water,
the temperature of which I prefer to be moderately warm. I now allow
it to stand for several days, stirring it occasionally until fermentation has
commenced. I then dry it by means of artificial heat, which I regulato
accordingly as I want it to be more or less glutinous. The resulting product
is now ground, mixed with hot water, and is then ready for use.
When the rice is unground, I, in like manner, treat it with hot water, by
preference, and not exceeding 170°. I keep the mass well stirred or con-
tinually in motion until the grains, by slightly triturating, will form a paste.
I then strain off the liquor, and allow fermentation to commence.
The product
is dried, as before described, ground, and mixed with water, and is then ready
for use.
The apparatus which I use for effecting the action upon the rice, as before
stated, is as follows:-I find it necessary during the operation to keep the
mass of rice in constant motion, and at an equable temperature. To effect
this, I place the rice in a large perforated octagonal cylindrical vessel. This
I surround with a covering of cloth of open texture; I then mount this,
preferably, horizontally, by means of the trunnions or axis, within a large
vat containing the water. Rotation being given to the cylinder the mass is
kept continually in motion and every portion of it in succession comes in
contact with the water, and thus keeps the temperature regular.
Having now described the nature of my Invention, and how the same is
manufactured and made, I now state that what I claim and wish secured to
me by the before in part recited Letters Patent is, the manufacture of starch,

page_text: or gum starch or dressing substance, to be used in the dressing of textile
fabrics and such like purposes, or in brewing or distilling, in the manner and
by the means substantially as herewithin set forth and described.
In witness whereof, I, the said William Maltby, have hereunto set
my hand and seal, this Twelth day of August, in the year of our 5
Lord One thousand eight hundred and sixty-one.
WILLIAM MALTBY. (L.B.)
