AN IMPROVED CHIMNEY FOR ARGAND AND OTHER BURNERS
Year: 1825

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
WITTY, of Sculcoats, in the County of York, 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 Thirtieth day of July, 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, admors, and assigns, or such others as I, the said
Richard Witty, my exors, admors, 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 IMPROVED CHIMNEY FOR ARGAND AND OTHER BURNERS;" in which said
Letters Patent 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 bo 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 Invention to consist in a peculiarly
formed top or cap, to be added to an ordinary chimney for argand or other
burners for the purpose of increasing the flame issuing from such burners,

page_text: 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 Drawing annexed
in the margin hereof, and the Figures marked thereon, that is to say :-
DESCRIPTION OF THE DRAWING.
Fig. 1 is a perspective view of my said top or cap, which may be made of
glass or metal as may be deemed most expedient according to the situation in
which it is to be applied. This top or cap is either to be dropped into the top
of an ordinary chimney to an argand burner, with the small end downwards,
as shown in Figure 2, or placed on the top of such a chimney with the
small end upwards, as shewn at Figure 3. When placed in either of theso
positions the conical sides of the top or cap contract the aperture at the top
of the chimney in such manner as to increase the flame issuing from such
burner, without causing a proportionally increased consumption of inflam-
mable matter, so that a great advantage is gained by the use of such top or
cap as aforesaid.
Now, whereas, my said improvement doth consist in such a top or cap, as
shewn at Figure 1, whether made of glass or metal, and its application in any
of the manners aforesaid to the chimney of an argand or other burner;
and whereas, such my said improvement 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
said Dominion of Wales, or 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 my said improvements, 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 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 January, in the year of our
Lord One thousand eight hundred and twenty-six.

aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
