Year: 1848

page_text: TO ALL TO WHOM THESE PRESENTS. SHALL COME, I, JAMES,
HENDERBON, of Surrey Canal Dock, Millwright, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her,
Royal Letters Patent under the Great Seal of the United Kingdom of
Great Britain and Ireland, bearing dato at, Westminster, the Fourteenth day
of August, One thousand eight hundred and forty-eight, in the twelfth year of
Her reign, did, for Herself, Her heirs and, successors, give, and grant unto me,
the said James Henderson, my exors, admors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said James Hen-
derson, my exors, adiñors,, and assigns, or such others as I, the said James
Henderson, my exors, adñors, or assigns, should at any time agree with,
and no others, from time to time and at all times. during the term of years
therein. expressed, should and lawfully might make,, use, exercise,.. and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "IMPROVEMENTS IN MACHINERY FOR CLEANSING AND POLISHING RICE,
PEARL BARLEY, AND OTHER GRAIN AND SEED;" in which said Letters Patent is
contained a proviso that J, the said James Henderson, should cause a par-
ticular description of the nature of my said Invention, and in what manner the
same is to be performed, by an instrument in writing under my hand. and
seal, to be inrolled in Her said Majesty's. High Court of Chancery within six
calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear..

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
James Henderson, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, that is to say :-
My Invention consists of covering the rubbing surfaces which act on rice,
pearl barley, and other grain or seed requiring like processes with emery.
And I would state, that the shape or arrangement of the rubbing surfaces
which are to act on the grain or seed may be varied.I-will, however, now
proceed to describe the arrangement of machinery which I prefer for carrying
out my Invention. I construct a cylinder about two feet six inches diameter,
and about two feet eight inches long. The frame. of such cylinder I make of
iron, and the ends and surface I cover with wood, and I clothe the ends and
periphery of such cylinder with canvass, which I strain tightly over the sur-
faces, and fasten the same with tacks, and then over the canvass I apply
emery (that degree of coarseness known as No. 1 I find most suitable for the
purpose), and I cause such emery to adhere by means of glue, and use the
emery heated to about the temperature of the glue. By this means I obtain
a cylinder covered all over with emery, which I employ in a cylinder formed
of wire cloth, with about fourteen holes to the inch, such cylinder having
closed ends and longitudinal' bars at intervals to give strength. The axis of
the working or emery cylinder passes through the two ends of the outer or
wire cloth cylinder; there being washers or stuffing boxes to prevent the
passage of the rice, grain, or seed where the axis passes through. I prefer
that the wire cylinder should be stationary and slightly inclined, so that the
working cylinder and its axis will also be slightly inclined from the horizontal.
The wire cloth cylinder is of such a size as to leave about one and a half
inches between it and the working cylinder at all parts. At the higher end
of the wire cylinder I make an opening just above the axis, and apply a
hopper thereto för feeding in the grain; and at the other end of the cylinder I
make an opening on one side of the axis, at which opening I employ a slide,
by which I can regulate the position at which the finished rice, pearl barley,
grain, or seed can flow out of the machine, and by which I can also regulate
the outflowing thereof, so that the rice, pearl barley, or seed may not remain
under process longer than necessary. I cause the working or emery cylinder-
to revolve at a speed of about two hundred revolutions per minute. By these
means I have found that the processes of cleansing and polishing of rice,
grain, and other seed requiring like processes can be performed with great
advantage.
Having thus described the nature of my Invention, and the best arrange-

page_text: ment of machinery I am acquainted with for performing the same, I would
wish it to be understood that I do not confine myself to the shapes and ar-
rangement of the parts, so long as surfaces covered with emery are employed;
but what I claim is, the coating the surfaces used for cleaning and polishing.
rice, pearl barley, and other grain or seed with emery.
In witness whereof, I, the said James Henderson, have hercunto set
my hand and seal, this Thirteenth day of February, in the year of our
Lord One thousand eight hundred and forty-nine.
