the screen, which by turning round to the right hand rises the said screen, and
to the left hand lowers it. h, the click to the last-mentioned notched wheel,
which acts. in the same manner and produces the same effect to such wheel as
the clicke does to the notched wheel d. i, the spring to the click h, which
acts in the same manner and produces the same effect to such click as the
spring does to the click e. k 1, k 2, handles at each corner of the said
machine, by which it is carried and removed. j, a line which goes or runs in a
groove cut in the circumference of the multiplying wheel, and in a groove
cut in the circumference of the pulley c to the fan, and which sets the fan in
motion. 1, line which goes or runs in a grove cut in the circumference of the
inside pulley of the multiplying wheel, and in a groove cut in the circumference
of the pulley 6 to the tumbler, and which sets the tumbler in motion. m, a
sieve called a screen. n, strings or cords, one end of each of which is fastened
on each side of the screen, and the other ends are fastened to the regulator by
which the screen is raised or lowered. o, the fall of the grain or seeds cleaned
out of the screen. p, the fall of the small grain or seeds after passing through
the screen. q, the tumbler's regulator, which prevents the grain or seeds falling
too fast into the riddle. r, the multiplying wheel. s, the handle which turns
the multiplying wheel. t, the conductor of the hulls, stems, and stones, which fall
over from the riddle. v, the pin to the conductor. u, the inside pulley of the
multiplying wheel.

The said Invention is performed in this manner (to wit): By putting
a quantity of wheat, barley, oats, rye, beans, or any sort of grain, or any kind
of seeds into the hopper, and turning the multiplying wheel, the fan, by the
motion of the line j, is turned round and creates a current of wind which
blows the chaff and dust from the grain or seeds falling from the hopper as
the tumblers turns, which is set in motion by the line i. The chaff and dust
falling from the hopper are seperated and blown away from the grain or seeds,
and fall at a distance in a heap on the ground floor or base. The hulls,
stems, and stones are blown against the conductor, and fall on the ground
floor or base in a second heap. The grain or seeds fall into a riddle, which is
shaken by the motion of the shaker x, x, fixed to the crank y; from the riddle,
the grain or seeds fall down into the screen, which is also shaken in the same
manner as the riddle is by the shaker w, whereby the large grain or seeds are
seperated from the small; the small grain or seeds pass or fall through the
screen, falling upon the ground floor or base in a third heap or parcel. The
large grain or seeds glide, fall, or run down the screen, and fall upon the
ground floor or base in a fourth heap, completely cleaned, sifted, and divided
for use.
In witness whereof, the said John Crang Hancock hath hereunto set
his hand and seal, the Seventeenth day of October, in the twenty-
ninth year of the reign of our Sovereign Lord George the Third, by
the grace of God of Great Britain, France, and Ireland King, Defender
of the Faith, and so forth, and in the year of our Lord One thousand
seven hundred and eighty-nine.
