Year: 1818

page_text: TO ALL TO WHOM HESE PRESENTS SHALL COME, 1, JAMES
HADDEN the younger, of Aberdeen, in Scotland, Manufacturer, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twelfth day of Novem-
ber, in the fifty-ninth year of His reign, give and grant unto me, the said
James Hadden, my exors, adññors, and assigns, His especial licence, full
power, sole privilege and authority, that I, the said James Hadden, my exors,
adiiors, and assigns, during the term of years therein mentioned, should and
lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "AN IMPROVEMENT IN
PREPARING, ROVING, AND SPINNING OF WOOL;" in which said Letters Patent
there is contained a proviso that if I, the said James Hadden, shall not par-
ticularly 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 Majesty's High Court
of Chancery within six calendar months next and immediately after the date
of the said Letters Patent, that then the said Letters Patent, and all liberties
and advantages whatsoever thereby granted, shall utterly cease, determine, and
become void, as in and by the same, relation being thereunto had, will more
fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the
said James Hadden the younger, do hereby describe and ascertain the
nature of my said improvement, together with an account of the manner
in which I have performed the same with the greatest success, that is
to say:-
That my said improvement doth consist in preparing wool, (by which tech-
nical expression I mean to imply drawing wool after it has been carded,
combed, or otherwise brought into a fit state for drawing), as also to rove and
spin all or either the same while in a heated state. Various methods may be
found of applying heat to wool during all or cither of the three said processes
of preparing, roving, and spinning. That which I have adopted, and which
I have found the most easily and perfectly to procure the advantages desired,
has been the introduction of cast-iron heaters into the retaining rollers used in
the said processes, by always using three of the said rollers, and by leading
the wool over half the circumference of each of the two upper of the said
heated rollers, thereby allowing it to pass over a sufficient length of heated
surface to become thoroughly warmed without retarding the other processes it
is undergoing at the time
