Year: 1819

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
WEATHERLY PHIPSON, of Birmingham, in the County of Warwick, Metal
Merchant, send greeting.
WHEREAS I, the said Joseph Weatherly Phipson, have, after much labour,
study, and expence, found out and invented "AN IMPROVEMENT IN MANUFAC
TURING PIPES, TUBES, OR CONDUCTORS POR GAS AND OTHER PURPOSES ;" and
whereas His Majesty King George the Third, by Letters Patent, bearing date
at Westminster, the Twenty-fourth day of April, in the fifty-ninth year of His
reign, after reciting my said Invention, and my Petition for the said Letters
Patent for it for the term of fourteen years, hath given and granted unto me,
the said Joseph Weatherly Phipson, my exors, admors, and assigns, especial
licence, full power, sole privilege and authority, that I, the said Joseph
Weatherly Phipson, iny exors, adñiors, and assigns, and every of them,
by myself or themselves, or by my and their deputy or deputies, servants
or agents, or such others as I, the said Joseph Weatherly. Phipson, my exors,
adiňors, or assigns, should at any time agree with, and no others, 'from
time to time and at all times thereafter during the term of years therein,
should and lawfully might use, exercise, and vend my said Invention within
that part of the United Kingdom of Great Britain and Ireland called England,
the Dominion of Wales, and Town of Berwick-upon-Tweed, in such manner
as to me, the said Joseph Weatherly Phipson, my exors, admors, or assigns,
or any of them, should in my or their discretion seem meet; and it is by
the said Letters Patent (amongst other things) provided that if I, the said
Joseph Weatherly Phipson, should not particularly describe and ascertain the
nature of my said Invention, and in what manner the same was to be per-

page_text: formed, by an instrument in writing under my hand and seal, and cause the
same to be inrolled in the 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 thereby granted,
should utterly cease, determine, and become void, any thing therein contained to
the contrary in anywise notwithstanding, as in and by the said Letters Patent,
inrolled in the High Court of Chancery, may more fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joseph Weatherly Phipson, do hereby declare that the nature of my said
Invention or Improvement, and the manner in which the same is to be
performed, are particularly described in the words following
:-
I take rolled copper of a thickness and breadth in proportion to the size of
the tube required, and form the same into a tube by drawing it through a
plate upon a mandrill, or without a mandrill. I then cause the edges of the
copper to be soldered together with Bath metal or silver solder, so as to form
a permanent and safe joint. I then dress off the superfluous solder, and again
draw the tube through the plate. This done, I take a piece of lead pipe and
adapt it to the purpose in view by drawing it through a plate on a mandrill of
the diameter of the tube required, and place it within the said copper pipe, and
by passing through it a conical mandrill attached to a rod I force the lead
pipe against the inner surface of the copper tube, so as to leave them in
perfect contact with each other. Or I prepare a lead pipe upon a mandrill of
the diameter of the tube required, and draw over it a copper pipe already
soldered, and pass them both together on the mandrill through a draw plate, so
as to bring the interior surface of the copper and the exterior surface of the
lead pipes into complete contact. The lead pipe is proof against the action of
the gas, and serves to conduct it without without the risk of escape; copper
is not, but it supports and defends the lead, admits of a better polish, and is
more pleasant to the eye than lead. Pipes or tubes thus constructed will
conduct various fluids and imflammable gases.
In witness whereof, I, the said Joseph Weatherly Phipson, have hereunto
set my hand and seal, the Fourth day of October, in the year of our
Lord One thousand eight hundred and nineteen.
JOSEPH WEATHERLEY (L.s.) PHIPSON.
Signed and sealed, by the said Joseph
Weatherly Phipson, in the presence of
JOHN SIMCOX,
Att', Birm™.
