page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting.
WHEREAS His present Majesty King George the Third, by His Royal
Letters Patent, tested at Westminster, the Twelfth day of June last past, and
in the fifth year of His reign, of His special grace, certain knowledge, and
meer motion, did, for Himself, His heirs and successors, give and grant unto
me, George Pickering, of Busy Cottage, near the Town and County of
Newcastle upon Tynė, Whitesmith, my executors, administrators, and assigns,
His special licence, full power, sole priviledge and authority, that I, the said
George Pickering, my executors, administrators, and assigns, and every of
us, by himself and themselves, or by my or their deputy or deputys, servants
or agents, or such others as I, my executors, admors, or assigns, should at
any time agree with (not exceeding five persons in number), and none
others, from time to time and at all times hereafter during the term of
fourteen years from the date of the said Letters Patent, should and lawfully
might make, use, and exercise, and vend, within that part of His Kingdom
of Great Britain called England, His Dominion of Wales, and Town of

page_text: Berwick upon Tweed, in such manner as to me, the said George Pickering,
my executors, adiñiors, and assigns, or any of us, should in our discretions
seem meet, my "NEW METHOD OF MAKING AND COMPLEATING AN IRON SCREW,
FIT FOR RAISING AND LIFTING UP TIMBER, AND OTHER PURCHASES, AND LOADING AND
STOWING OF HEMP OR OTHER GOODS IN AND ON BOARD OF SHIPS OR VESSELS, UPON A
CONSTRUCTION OR PRINCIPLE NEVER BEFORE INVENTED, USED, OR MADE KNOWN,"
and which I, by long study, application, and labour, by many experiments and
at great expence, found out, invented, and brought to perfection, with
such other powers, libertys, and priviledges, as is and are in and by the said
Letters Patent expressed; subject nevertheless to a proviso therein contained,
that if I, the said George Pickering, should not particularly describe and
ascertain 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, and cause
the same to be inrolled in His said Majesty's High Court of Chancery within
four kalendar months next and immediately after the date of the said Letters
Patent, that then the same Letters Patent, and all libertys and advantages
whatsoever thereby granted, should utterly cease, determine, and become void,
as in and by the said Letters Patent, whereunto relation being had, may and doth
more fully and at large appear.
NOW KNOW YE, that I, the said George Pickering, in pursuance of
the said proviso, do hereby declare that the said new invented iron screw
consists of the frame, composed of four strong square bars firmly fixed
together, the lower ends of the upright pieces ending in pikes, to prevent
the machine from sliding when used; and in the middle of the upper cross
bar is formed a circular hole or collar to receive the cylinder and support the
horizontal wheel, whose teeth are perpendicular to the plane of the wheel, in
the nature of a cogg wheel; the cylinder serves as a fixed axis to the horizontal
wheel, and is hollow, being wrought into a female screw, which is adapted to
the square worm of the strong male screw, the upper end of which expands
into two or more fangs or claws, and the lower end is rivetted into the cros
bar, whose ends are grooved to fit the upright bars of the frame, and slide
easily between them. On the upper part of the frame is fixed the box con-
taining the cog wheel and cylinder, and also the wallower or pinion, one end
of whose axis comes through the side of the box, and the other turns in a hole
made in a piece of iron fixed in the cover of the box, or else in a cross bar
whose ends are fixed in the sides of the box; when the cover is fastened down
the pinion is turned about by a winch, and so drives the horizontal wheel with
the hollow cylinder or female screw which works the great screw and makes

page_text: it act against any obstacle; all which are more particularly laid down in the
plan or referrence below.
In witness whereof, I, the said George Pickering, have hereunto set my
hand and seal, the Tenth day of August, in the fifth 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 sixty-five.
GEORGE PICKERING. (L.S.)
The whole machine is made of iron, and consists of the frame A, B, B, A,
composed of four strong square bars firmly fixed together; the lower ends B, B,
of the upright pieces ending in pikes to prevent the machine from sliding when
used; and in the middle of the upper cross bar A, A, is formed a circular hole
or collar C, to receive the cylinder D and support the horizontal wheel E,
whose teeth are perpendicular to the plane of the wheel, in the nature of a cog
wheel; the cylinder D serves as a fixed axis to the horizontal wheel, and is
hollow, being wrought into a female screw, which is adapted to the square
worm of the strong male screw F, the upper end of which expands into two
or more fangs or claws, and the lower end is riveted into the cross bar G,
whose ends are grooved, to fit the upright bars of the frame, and slide easily
between them; on the upper part of the frame is fixed the box H, containing
the cog wheel and cylinder, and also the wallower or pinion I, one end of
whose axis K comes through the side of the box, and the other L turns in a
hole made in a piece of iron fixed to the cover M of the box, or else in a cross
bar, whose ends are fixed in the sides of the box; when the cover is fastned
down, the pinion is turned about by the winch N, and so drives the horizontal
wheel with the hollow cylinder or female screw, which works the great screw
and makes it act against any obstacle.
