page_text: LETTERS PATENT to Isaac Noah Davis, of Brentford, in the County of
Middlesex, for the Invention of "PRODUCING SPIRIT FROM RICE, MAIZE,
BARLEY, OR OTHER GRAIN."-A communication from abroad by A. E.
Ripoche, of Rouen, in France.
Sealed the 11th January 1861, and dated the 19th July 1860.
PROVISIONAL SPECIFICATION left by the said Isaac Noah Davis at
the Office of the Commissioners of Patents, with his Petition, on the
19th July 1860.
I, ISAAC NOAH DAVIS, of Brentford, in the County of Middlesex, do hereby
declare the nature of the said Invention for "PRODUCING SPIRIT PROM RICE,
MAIZE, BARLEY, OR OTHER GRAIN," to be as follows, and consists of a mode of
treating rice, maize, barley, or other suitable grain, in order to saccharify the
grain. For this purpose I put the grain to be operated upon in an open mash
tun made of wood or other suitable material not easily affected by acid. I
next put in a solution of bydrochloric acid in-water or any other suitable acid
capable of saccharifying the grain. High-pressure steam is then blown in
and through the mixture until the completion of the saccharification of the
grain.
It is then discharged into an under back made of any suitable material not
easily affected by acid to be neutralized, and then fermented and distilled as
usual.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ISAAC
NOAH DAVIS, of Brentford, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of July, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-second year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Isaac Noah Davis, Her special licence that I, the said Isaac Noah Davis,
my executors, administrators, and assigns, or such others as I, the said
Isaac Noah Davis, my executors, administrators, and assigns, should at any
time agree with, 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 "PRO-
DUCING SPIRIT FROM RICE, MAIZE, BARLEY, OR OTHER GRAIN," a communication
to me from abroad by A. E. Ripoche, of Rouen, in France, upon the condition
(amongst others) that I, the said Isaac Noah Davis, my executors or admi-
nistrators, 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 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 Isaac Noah Davis, do hereby declare
the nature of my 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, that is to say:-
My Invention consists in an improved method in the production of alcohol
from rice, maize, millet, dabree, and other descriptions of grain. For this
purpose I put into a mash tun made of wood (or any other material not
easily affected by acid), having a chimney or opening to exhaust the waste
steam, the rice, grain, or substance, with ten per cent. of hydrochloric or
other acid capable of saccharifying the rice or other grain, diluted with water
according to the quantity of material used. High-pressure or superheated
steam is then blown in through and out of the mixture until the completion
of the saccharification of the grain. The mixture is then let into an

page_text: under back, where it is neutralized with whiting; it is then fermented and
distilled according to the well-known method of the usual distillers.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, the improvenient I claim consists in
blowing high pressure or superheated steam into the mixture, and exhausting
in through the chimney of the mash tun.
In witness whereof, I, the said Isaac Noah Davis, have hereunto set
my hand and seal, this Nineteenth day of January, in the year of our
Lord One thousand eight hundred and sixty-one.
I. N. DAVIS. (L.B.)
