Year: 1825

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
WITTY, late of the Town of Kingston upon Hull, in the County of the
same Town, and of Sculcoates, in the County of York, but now of Shelton, in
the County of Stafford, Civil Engineer, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-fifth day of March, in the sixth year of his reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Richard Witty, His especial licence that I, the said Richard Witty, my exors,
aditiors, and assigns, or such others as I, the said Richard Witty, my executors,
adiiors, or assigns, should at any time agree with and no others, from time to
time and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, and also in all His said Majesty's Colonies and
Plantations abroad, my Invention of "AN IMPROVEMENT IN THE METHOD OF
LIGHTING BY GAS BY REDUCING THE EXPENCE THEREOF;" in which said Letters

page_text: Patent there is contained a proviso obliging me, the said Richard Witty, by
an instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same is to
be performed, and to cause the same to be inrolled in His said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Richard Witty, do hereby declare the nature of my said Invention to consist
In the application to gas burners of a chimney contracted at its upper part in
such manner as to cause any given quantity of gas to give a greater light and
consume less rapidly when burned within one of my said chimneys, than when
burned within an ordinary chimney, thereby reducing the expence of obtaining
that quantum of light from gas. And in further compliance with the said
proviso, I, the said Richard Witty, do hereby describe the manner in which I
perform my said Invention by the following description thereof, reference
being had to the Figure in the margin hereof; that is to say, I place over any
ordinary gas burner, and in the ordinary manner, a glass chimney of the shape
represented by the Figure in the margin, or of any other shape which shall cause
the upper part of the chimney to be about three quarters of an inch less in
diameter than the lower part of it in chimnies whose length shall be about
eight inches and a half, and whose largest diameter shall be about one inch and
a half. And such a chimney as aforesaid, applied to the gas burners as aforesaid,
for the purpose aforesaid, being, to the best of my knowledge and belief,
entirely new, and never before used within that part of His said Majesty's
United Kingdom of Great Britain and Ireland called England, His Dominion
of Wales, and the Town of Berwick-upon-Tweed, nor in any of His said
Majesty's Colonies or Plantations abroad, I do hereby declare this to be my
Specification of the same, and that I do verily believe this my said Specification
doth comply in all respects, fully and without reserve or disguise, with the
proviso in the said herein-before in part recited Letters Patent contained;
wherefore I do hereby claim to maintain exclusive right and privilege to my
said Invention.
In witness whereof, I, the said Richard Witty, have hereunto set my
hand and seal, this Twenty-seventh day of August, in the year of
our Lord One thousand eight hundred and twenty-five.
RICH (Ls.) WITTY.
