WHEREAS His present most Excellent Majesty King George the Third,
in and by His Royal Letters Patent under the Great Seal of Great Britain,
bearing date at Westminster, the Eighteenth day of September, in the forty-
first year of His reign, for Himself; His heirs and successors, did give and
grant unto me, the said Zachariah Barratt, His especial licence, full power,
sole privilege and authority, that I, the said Zachariah Barratt, my executors,
administrators, and assigns, by myself or themselves, or by my or their deputy
or deputies, servants, or agents, or such others as I, the said Zachariah
Barratt, my executors, administrators, or assigns, should at any time agree
with, and no others, during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within that part of His said
Majesty's United Kingdom called England, His Dominion of Wales, and
Town of Berwick-upon-Tweed, my Invention of "A MORE SIMPLE, CONCISE,
AND CHEAP METHOD OF GRINDING CORN OR OTHER GRAIN THAN HAS BEEN HITHERTO
USED, BY A NEW INVENTED MILL OR MACHINE, EITHER MOVEABLE OR IMMOVEABLE,
AND INTENDED TO BE WORKED BY WATER, WIND, HORSES, HAND, OR OTHERWISE;"
in which said Letters Patent there is contained a proviso, obliging me, the said
Zachariah Barratt, by an instrument in writing under my hand and seal, par-
ticularly to describe and ascertain the nature of my said Invention, and in
what manner the same is to be performed, and to cause the same to be inrolled
in His said Majesty's High Court of Chancery within one calendar mouth next
and immediately after the date of the said recited Letters Patent, as in and by
the same, reference being thereto had will more fully and at large appear,

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Zachariah Barratt, do hereby describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, by the Plan or
Drawing in the margin of these Presents, and in manner following (that is to
say):-
This mill may be conveniently erected in a garden or croft, wherever the
wind has access, and is so light as to be capable of being turned by the hand;
or the sails may occasionally be affixed in a horizontal position to the upright
shaft, and, on taking down the shed over the mouth of the hopper, the power of
a horse may be applied when the wind fails. It will, perhaps, be necessary on
this occasion to have the wheel A (Fig. 1) enlarged, which may be readily
effected by screwing on an additional wheel in quadrants or octants, as may be
most preferable. The whole apparatus may be conveniently fixed on a centre,
with a gudgeon at each end, to the gable end of a house, barn, or granary, a
peculiar provision being planned in the sails for that purpose. It will appear
obvious that its internal construction is suited to any power which may be sub-
stituted for the sails; and it will be superfluous to hint to a workman how
hand mills may be connected with the crown or spur wheels at the same time
to grind malt, split beans, cut hay, straw, &c.
Fig. I., A is a crown and spur wheel; it has three concentric circles 1, 2, 3,
with teeth adapted to the spur wheel B on the mill shaft, the teeth in the
second being higher than the first, and in the third higher than the second, to
meet the clevation of the mill shaft above the plane of the crown wheel. These
circles are called speed wheels, serving to increase the velocity of the stones, or
to preserve it when the velocity of the wind decreases. This wheel may be
dispensed with with one or two pair of stones, the nut on the spindle being
made contrate instead of spur, and immediately connected with the spur wheel
B, affixed to the axis of the mill by means of a sliding box A (Fig. II.), and
secured in its position by the screw S (Fig. II.), by which it is adapted to cach
of the concentric circles, as the crown wheel is required to move faster or
slower. C is the brake wheel, which retards or stops the motion of the sails by
its friction with the wedge W; see for its position on the axis (Fig. II). Dis
a circular plate of cast iron, belonging to and being part of the iron axis of the
mill shaft, or the upright axis of the crown wheel. Upon this plate, on the
continuation of the spindle (see d Fig. II.), is placed the cross, Fig. IV., to
which it is fastened by four screws, passing thro' the four holes of both, and the
extremity of the arm of each sail, into which the said cross is inserted at the
slot (Fig. III.), and secured by another screw and moveable iron bandages.
E is the gallows, which supports the gudgeon of the mill shaft, which, moving

page_text: on a centre at the end e, permits the wheel B to be thrown in or out of gear
by means of the wedge F. The stones moved by the nut S are placed in a box
in the frame G, fixed on a platform m, which sliding on the rails n, n, the
spindle is thrown out of gear, by the screw E passing through the iron rod,
which, by the screw I, raises or depresses the bridge tree. a, a, is an iron axis,
with small wheels at each end, for turning a sifting machine, Fig. III. A is
the sail arm, into which at the mortise a is put the supporting arm D at its
end b, and secured by a peg. The first part of the sail E falls into the slot C,
and is kept in its position by the guards d and a peg in the grove B. The two
other fan sails F, F, slide on each side of the fixt one, moving on a centre at
the narrow extremity, and when expanded to the wind are kept in their posi-
tions by pegs in the same grove catching in the notches at the other extremity;
these sails are made of thin boards. When the sails are affixed to a gable
end, whence it will occasionally be necessary to catch the wind on opposite sides
of the sail, the ledge e is attached to each sail arm, into the nicks on which
falls the spring m of the adjoining sail, by which means the sails are turned
to opposite degrees of obliquity. The frame of the machinery as depicted in
the Specification turns on castors on a circular base.
In witness whereof, I, the said Zachariah Barratt, have hereunto set
my hand and seal, the Thirtieth day of September, in the year of our
Lord One thousand eight hundred and one.
AND BE IT REMEMBERED, that on the same Thirtieth day of Sep-
tember, in the year above mentioned, the aforesaid Zachariah Barratt came
before our Lord the King in His Chancery, and acknowledged the Speci-
fication aforesaid, and all and every thing therein contained, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute in that case made and provided.
