TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BELL, of the City of Dublin, Merchant, send greeting
WHEREAS Her present most Excellent Majesty, by Her Letters Patent
under the Great Seal of Great Britain, bearing date at Westminster, the,
First day of March; in the sixth year of Her reign, did; for Herself, Her
heirs and successors, give and grant unto me, the said George Bell; my exors,
adñiors, and assigns, Her especial license, full, power, sole privilege, and
authority, that I, the said George Bell, my, exors, adññors, and assigns, and
such others..as I, the said George Bell, my exors, admors, and assigns, should
at any time: agree with, and no others, from time to time and at all --times
hereafter during the term of years, therein expressed, should and lawfully
might make, use, exercise, and vend, within that part of the United Kingdom
of Great Britain and. Ireland called England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVED, MACHINES WHICH
FACILITATE THE DRYING OF MALT, CORN, AND SEEDS, ALSO THE BOLTING, DRESSING,
AND SEPARATING OF FLOUR, MEAL, AND ALL OTHER SUBSTANCES REQUIRING TO BE
SIFTED;" in which Letters Patent there is contained a proviso, requiring
that I, the said Geor Bell, shall particularly describe; and ascertain the
nature of my said Invention, and in what manner the same is to be per-
formed, 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 now reciting Letters Patent.
.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Bell, do hereby declare that the nature of my said Invention, and the

page_text: manner in which the same is to be performed, are particularly described and
ascertained in and by this present instrument in writing under my hand and
seal, in the words herein-after written, and by reference to the Drawings-
annexed :-
The object of my Invention, in the first place, is to enable millers and others
to dry malt, corn, or seeds by means of one of my improved machines more
uniformly, in a much shorter time, and at less cost, than they can by any
process at present in use; then by the other machine to bolt, dress, sift, or
separate substances in a superior manner, producing a greater quantity of
fine flour than can be obtained by any other mode at present used; also
facilitating the changing of the wire webb, by the sieve being divided into
moveable compartments; then the obtaining by means of the cylinder every
portion of flower that is contained in any article, and separating it at the same
time, according to its fineness. And in order to give the best information in
my power for enabling a workman to carry out my Invention, in the Drawing
Number 1 hereunto annexed I have given a sketh of the drying machine.
A shews the drying cylinder, within which there is another cylinder, both
covered either with perforated plates of iron or zinc, or strong wire web, with
apertures small enough to prevent the malt, corn, or seeds passing through
which are placed in the space B; into the inner cylinder the hot air is driven
from the stove C by the fan blower D, and escaping by the apertures, passes
through the malt, corn, or seeds in space B, which are constantly changing
their position from the revolving motion, aided by small bars for turning the
corn, and so forth, rising from the circumference of the inner cylinder about
one-fourth up the space B. E, friction wheel for cylinder to revolve on;
F, purchase wheel to propel cylinder; G, one pair of bevel wheels to propel
the fan; H, frame of cylinder; I, door for filling and discharging the corn or
seeds, with slide bar to fasten same; K, winch handle. The outer cylinder or
space B may be also divided in compartments, if required, or the bars for
assisting the turning of the corn or seeds omitted.
In the Drawing No. 2 is the machine for bolting, dressing, sifting, or sepa-
ting; A being a vertical section of the sieve; a, a, the upright shaft, a portion
of which is surrounded with wood; B, a loose wheel with rack teeth on the
upper side; these teeth work into corresponding ones, fixed at bottom of sieve;
C, a circle of wood fixed under and having four screws passing through it into
B; by turning those screws the loose wheel presses on the bottom of the sieve
and raises it to the brush. D shews construction of brush, held firm to the
shaft by the screw bolt E; F, a section of a raised circle on the top of the
.brush, where the articles to be sifted pass to the sieve through four reticulated

page_text: apertures e; H, a small brush placed in this. circle that forces the meal into
the sieve; on the top of this circle are a range of rack teeth which keep the
hopper in motion; the sieve is prevented moving out of its position by two
stays of leather fixed on each side. I, shoot from sieve to cylinder; J, a cylinder
for further separation. This may be altered to sieves placed horizontally to
be worked in the same manner, but the cylinder is preferable. K, four
revolving wheels to support and turn cylinder, those at front with rack teeth
risers giving it a joggling motion; L represents the fan inside the cylinder,
the red line on shaft shews its obliquity, M, the residue discharging shoot;
1, 2, 3, reticulated divisions of cylinder, covered with various wire web; 4,
divisions under, to keep the sifted parts separate; N, a round-bottomed pully
on fan shaft turns pully O, and a similar one at back, by a cord or band passing
twice round it; P is; the pully which receives. motion. from Q; R, driving
pulley; S, S;-driving cog wheels; T, flat surface of sieve, showing moveable
compartments to be covered with wire web; U, opening, for upright. shaft ;
V, a circle of tin round same, to prevent the meal or substance touching the
shaft; W, under part of sieve frame, with fixed rack. wheel, similar to. B;
X, ends of cylinder, shewing the openings through which the. substance for
sifting passes into and out of same.
Having thus described the nature of my Inventions, and the. manner of
carrying the same into effect, I hereby declare I do not claim any of the parts
herein-before described taken separately, or which are now in use; but I do
claim as new and my Invention, the mode in which the hot blast of air that is
driven into the cylinder is made to pass through the perforations into the
compartment B containing the malt, corn, or seeds, and the way the steam or
vapour generated escapes, the air drying at the same time such articles as
the said compartment or compartments may contain. And I also claim. the
manner in which the cylinder is made to revolve upon wheels instead of an
axis, when the machine is in motion. And as to the bolting, dressing, sifting, or
separating, I claim the mode of application of the large horizontal brush, which
when revolving keeps the meal or other substance in motion on the sieve and
causes the finer parts to pass down; also the manner the meal or other
substance is conveyed into the sieve through four reticulated apertures round
the centre of the brush, also the side opening that discharges the undressed
part into the cylinder. I also claim the peculiar application of the rack
wheels under the centre of the sieve which gives it a joggling motion; likewise
the application of the four-screws under the centre of the sieve, and the four
screws at the circumference of the circle of the sieve, which, by turning raises
it to the brush. I also claim the manner the unattached cylinder is made to

before described.
