Year: 1864

page_text: LETTERS PATENT to John Yearsley, of East Smithfield, in the County
of Middlesex, Rice Merchaut, and Edward Timbrell, of Saint George's in
the East in the same County. Foreman. for the Invention of "IMPROVE-
MENTS IN APPARATUS FOR CLEANING RICE, AND A NEW COMPOSITION TO BE USED
Sealed the 2nd June 1865, and dated the 5th December 1864.
PROVISIONAL SPECIFICATION left by the said John Yearsley and,
Edward Timbrell at the Office of the Commissioners of Patents, with.
their Petition, on the 5th December 1864.
We, JOHN YEARSLEY, of East Smithfield, in the County of Middlesex, Rice
Merchant, and EDWARD TIMBRELL, of Saint George's in the East, in the same
County, Foreman, do hereby declare the. nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR CLEANING RICE, AND A NEW COMPOSITION TO
BE USED THEREIN," to be as follows:-
Our Invention consists in the employment of a drum coated with the com-
position hereafter described, which we substitute for the stones now ordina-
rily used in rice mills for cleaning rice; the drums are worked in a similar
manner to the said stones. Our Invention also consists in a composition
hereafter described to be used in lieu of stones in the cleaning of rice.
We prefer to roughen the surface of the drum, or when formed of wood to
insert pegs, pins, nails, or other like similar holding agents therein for the

page_text: purpose of affording a better hold to our composition. The composition is
formed of the following ingredients in or about the proportions named :-Two
parts of emery, one part of roman cement, and as much glue as will hold
these ingredients and form with them a pasty or plastic mass. We dissolve
the glue under heat and gradually stir in the other materials, and we apply
the composition warm. On cooling it sets and hardens, and when cold the
drums coated with it are fit for use.
We have stated emery as being one of our ingredients as we find it best
suited to the purpose of our Invention, but powdered or ground glass or other
like gritty material may be substituted for or mixed with it, though with less
beneficial effect.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Yearsley and Edward Timbrell in the Great Seal
Patent Office on the 5th June 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
YEARSLEY, of East Smithfield, in the County of Middlesex, Rice Merchant,
and EDWARD TIMBRELL, of Saint George's in the East, in the same County,
Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of December, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and succèssors, give and grant unto
us, the said John Yearsley and Edward Timbrell, Her special licence
that we, the said John Yearsley and Edward Timbrell, our executors,
administrators, and assigns, or such others as we, the said John Yearsley and
Edward Timbrell, our 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
"IMPROVEMENTS IN APPARATUS FOR CLEANING RICE, AND A NEW COMPOSITION TO BE
USED THEREIN," upon the condition (amongst others) that we, the said John
Yearsley and Edward Timbrell, or one of us, our executors or administrators,
by an instrument in writing under our, or one of our, 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

page_text: 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 we, the said John Yearsley and Edward Timbrell,
do hereby declare the nature of our 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, reference being had to the Drawings
hereunto annexed, that is to say:-
Our Invention consists in the employment of a drum coated with the com-
position hereafter described, which we substitute for the stones now ordinarily
used in rice mills for cleaning rice; the drums are worked in a similar
manner to the said stones. Our Invention also consists in a composition hero-
after described to be used in lieu of stones in the cleaning of rice.
We prefer to roughen the surface of the drum, or when formed of wood to
insert pegs, pins, nails, or other like similar holding agents thereon, or to fix
strips of iron thereon, for the purpose of affording a better hold to our compo-
sition.
The composition is formed of the following ingredients in or about the pro-
portions named:-Two parts of emery, one or two parts of roman cement, and
as much glue as will hold these ingredients and form with them a pasty or
plastic mass. We dissolve the glue under heat and gradually stir in the other
materials, and we apply the composition warm upon the drums, which we pre-
fer to be previously coated with hot glue. On cooling the composition sets
and hardens, and when cold the drums coated with it are fit for use, but will
be better if allowed to remain from two to three weeks to dry.
We have stated emery as being one of our ingredients as we find it best
suited to the purpose of our Invention, but powdered or ground glass or other
like gritty material may be substituted for or mixed with it, though with less
beneficial effect.
Figure 1 of the accompanying Drawings is a side elevation, and Figure 2
an end elevation, of one of our drums. A is the drum, formed of wood and
covered with punched iron; B, B, are ribs of punched iron fixed thereon;
C is an inner revolving cylinder enclosed in an outer case D, as usual in rice
mills. The iron is punched to afford a better hold to the glue and composition.
The drum and strips of iron are then coated with hot glue, and the composition
before described is applied warn thereon. On cooling the composition sets
and hardens as before stated. We do not limit ourselves to any particular
form or construction of drum.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim as our improve-

page_text: ments in apparatus for cleaning rice the employment of a drum coated
with the composition herein-before described in substitution for the ordinary
stones now used in rice mills.
And second, we claim the improved composition for cleaning rice herein-
before described.
In witness whereof, I, the said John Yearsley, have hereunto set my
band and seal, this Fifth day of June, One thousand eight hundred
and sixty-five.
JOHN YEARSLEY. (L.S.)
