page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MANNALL, of Colchester, in the County of Essex, Joiner and Cabinet Maker,
send greeting.
WHEREAS His most Excellent Majesty King George the Third, by
His Letters Patent, bearing date at Westminster, the Ninth day of June,
in the twenty-ninth year of His reign, did give and grant unto me, the
said John Mannall, His special licence that I, the said John Mannall, during
the term of years therein mentioned or expressed, should and lawfully might
make, use, exercise, and enjoy, within England, Wales, and Town of Berwick-
upon-Tweed, and also in all His Majestie's Colonies and Plantations abroad,
my invented "MACHINE OR WHEEL CALLED A WINDLASS WHEEL, WHICH BEING
AFFIXED OR PLACED TO AN ENGINE OR CRANE FOR LIFTING BURTHENS OR
WEIGHTS, WILL LIFT MORE PONDEROUS AND HEAVY BURTHENS THAN
ENGINE OR CRANE FOR THE LIKE PURPOSE EVER INVENTED;" in which said
Letters Patent there is contained a proviso obliging me, the said John
Mannall, under my hand and seal, to cause a particular description and
ascertain the nature of my said Invention, and how the same is to be
performed, to be inrolled in His Majestie's High Court of Chancery, within
one calendar month after the date of the said recited Letters Patent, as in

ANY
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Mannall, do hereby certify and declare the Specification of my said
Invention, and the method of using and working the same, and the opera-
tion thereof, to be as follows, that is to say:-

page_text: The Plan of the said machine is hereunder drawn. The dimentions of the
large toothed wheel in the said Plan marked A, B, and C, to be made at dis-
cretion; on each axis is to be fixed a smaller wheel, toothed to answer to the
revolutions. The first power is to be supposed the windlass or barrel, in the
said Plan marked D, on which the rope, chain, or other devise for raising the
weight is to be applied; to that windlass or barrell is fixed the larger wheel,
toothed, A; affixed to the axis of this wheel is a square bar or other matter
for the manel or other power to be applied, either by wynch handle or lever; at
the extremity of this large wheel toothed acts a smaller wheel toothed, and
fixed to or one with a larger wheel toothed as B. To the axis of this wheel is
a square bar or other devise for applying. a. wynch handle or lever for the
application of manual or other strength, which is the second power. At the
extremity of this larger wheel toothed acts a smaller wheel toothed, fixed to or
one with a large wheel toothed as C; on the axis of this wheel is a square for
applying power as before stated, which is the third power, and so on ad
infinitum. This engine may be worked either vertically or horizontally on
either side the windlass or barrell D.
In witness whereof, I have hereunto set my hand and seal, the Seventh
day of July, in the year of our Lord One thousand seven hundred and
eighty-nine.
JOHN MANNALL. (L.S.)
