CERTAIN. IMPROVEMENTS IN WIRE-DRAWING
Year: 1819

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROCKEDON, of Poland Street, in the County of Middlesex, Gentleman, send
greeting.
WHEREAS His late 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 Twentieth day of
September, in the fifty-ninth year of His reign, give and grant unto me, the
said William Brockedon, my exors, admors, and assigns, His especial licence,
full power, sole privilege and authority, that I, the said William Brockedon,
my exors, admors, 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 "CERTAIN.
IMPROVEMENTS IN WIRE-DRAWING;" in which said Letters Patent there is con-
tained a proviso that if I, the said William Brockedon, shall not particularly
describe and ascertain the nature of my said Invention, and in what manner
hand and
the same is to be performed, by an instrument in writing under my
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
William Brockedon, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are particularly
described and ascertained by the following Specification thereof (that is to
say) :-
Instead of the usual mode of drawing cylindrical wire through holes made
in plates of steel, iron, or other metals or compositions of metals, I make or
cause to be made, by drilling and polishing in the usual methods employed by
lapidaries, &c., cylindrical or conical holes, with their extremities rounded off,
through diamonds, saphires, rubies, chrysolites, or any other fit and proper
hard gems or stones, which I mount or set in blocks, frames, or plates of
metal or other fit substances proper for fixing or securing them for use, and
the metal or composition of metals to be made into wire is to be drawn
through these holes in the usual mode of wire-drawing. The wire may be
drawn through either end of the hole; but I prefer entering it at the smallest
end, and drawing from the larger end of the hole, because the gems or stones
will present in this direction a firmer resistance against the action of the wire
in drawing. The holes in these gems or stones must be made of successive
sizes according to the nature of the metal or composition of metals to be
drawn into wire through them, and by which the wire is reduced, as in the
usual way. The wire may be made of iron, steel, brass, copper, silver, gold,
platina, copper silvered or gilt, or silver gilt, or any other metal or composition
of metals fit or proper to be made into wire. I do not' point out any parti-
cular manner of adjusting the blocks, plates, or frames for the purpose of
drawing wire, as that will be left to the judgment and discretion of the work-
men usually employed in wire-drawing, the object of my Invention simply
being the substituting of perforated gems or stones for making round wire in
place of holes made in metal draw plates, as they afford the means of making
each wire so drawn more perfectly equal and cylindrical throughout its whole
length, owing to the hard substances in which the holes are made resisting the
friction of the metal in passing through the holes, whilst at the same time
the holes themselves are less liable to become galled or enlarged by the wire
in passing through them than when made in metal plates.
'
In witness whereof, I, the said William Brockedon, party hereto, have
hereunto set my hand and seal, this Seventeenth day of November, in
the year of our Lord One thousand eight hundred and nineteen.
WILLIAM (L.S.) BROCKEDON.
