Year: 1797

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
FERRYMAN, Rector of Iping, in the County of Sussex, Clerk.
WHEREAS His most Excellent Majesty King George the Third, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-fourth day of January, in the thirty-seventh year of
His Majesty's reign, did give and grant unto me, the said Robert Ferryman, His
special licence, full power, sole priviledge and authority, that I, the said Robert
Ferryman, my exors, adññiors, and assigns, should and lawfully might, during
the term of years therein expressed, make, use, exercise, and vend, throughout
that part of His Majesty's Kingdom of Great Britain called England, the
Dominion of Wales, and Town of Berwick-upon-Tweed, my Invention of
"A MACHINE FOR BLANCHING, GRINDING, AND DRESSING OF CORN;" in which said
recited Letters Patent is contained a provisoc, obliging me, the said Robert
Ferryman, by writing under my hand and seal, to cause a particular
description of the nature of my said Invention, and in what manner the
same is to be performed, to be inrolled in His Majesty's High Court of
Chancery within ono calendar month next after the date of the said
recited Letters Patent, as in and by the said Letters Patent, and the
Statute in' that behalf made, relation being thereunto had, may more at large
appear.
NOW KNOW YE, that in compliance with the said provisoe, and in
pursuance of the said, Statute, I, the said Robert Ferryman, do hereby declare

page_text: that my said Invention of A Machine for Blanching, Grinding, and Dressing
of Corn is described and ascertained in the annexed Drawing and the
following description thereof, that is to say:
A, A, A, A, is a frame to support the different parts of the machine; No. 1
represents the part for taking off the outer skin or corolla of the wheat.
Between the dotted lines is a roller B, with centres at a, a, and a winch c, a fly
wheel d, a grooved wheel e, and a line f, to turn the smaller wheel g, on the
centre of the fan h; oblique grooves are cut in the roller, and strips of leather
nailed upon it, as is more clearly seen by the seperate roller C; i, i, are two
smaller rollers; j, a piece of strong cloth fastened to one roller passing under
the large roller B, and over the other roller, and attached to a third roller
k, which serves as a weight to keep the cloth close to the larger roller B; lis
a brush lying upon the larger roller; m, a rubber with a flashing of
leather nailed to it, all of which is more clearly shewn by section D; 2 is the
greater roller; o, o the two smaller rollers; P, p. p, p, the cloth rolled upon a
third roller q; is a brush; s the rubber and flashing of leather; t, the hopper.
The wheat is put into the hopper t, and by the brush r is spread even on the
large roller n, and. by the oblique. grooves: is carried. round within the cloth
P. p. p, p, and rubbed against the rubber &, which by the time it reaches the
lower end compleatly rubs of the outer coat; it then falls down before the fan
at u, which blows away the bran or chaff, and the wheat falls into the shoot w,
to, and, is conveyed to the part No. 2 to be ground; the dotted part is a
conical stone with furrows, similar to a common mill, nicely fitted into
two other stones y,, y, as, is better seen by a top view E; ;, is tho
spindle resting on. a centre at a, a, supported by the bar b, b, b, b, which
may be raised or depressed by the screws c, c, c, c; d, d, is a toothed wheel
fitted on the spindles, . turned by another wheel e, e, fitted on a spindle f, f, on
the end of which is another wheel. g,g, turned by the wheel 'h, h, which is fitted
on the centre of the greater roller B. The corn is received from the shoot
, w, in at the top of the conic stone a, which by rubbing it against the side
stones y, y, compleatly reduces it to flour before it is discharged at the bottom,
from whence it passes to the part No. 3. i,i, is a circular brush, working on
a hollow centre j,j, and supported by the transverse bars k, k, k, k. 1,1,1,1, a
fine wire sieve inclosing the brush; the flour is conducted from the bottom of
the mill by the tube m, m, into the centre of the brush i, i, which being turned
round by the spindle,, flies lightly over the sieve.and brushes out the flour,
which is received into a drawer beneath. The bran is thrown off by the
centrifugal motion, and forced out at the opening in the side of the sieve
at 11, 7, and is received into another drawer below. The moving powers may

advantage than when conjoined.
In witness whereof, I, the said Robert Ferryman, have hereunto set
my hand and seal, this Twenty-fifth day of January, in the year of our
Lord One thousand seven hundred and ninety-seven.
