Year: 1837

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
Cook, of Birmingham, in the County of Warwick, Brass Founder, send
greeting.
WHEREAS Her present Majesty most Excellent Majesty Queen Victoria,
by Her Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Ninth day of December, in the first year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Ben-
jamin Cook, Her especial licence, full power, sole privilege and authority,
that I, the said Benjamin Cook, my exors, adññors, and assigns, or such
others as I, the said Benjamin Cook, 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, my Invention of "AN IMPROVEMENT IN GAS BURNERS COMMONLY
CALLED OR KNOWN BY THE NAME OF ARGAND BURNERS;" in which said Letters
Patent is contained a proviso, that I, the said Benjamin Cook, shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in Her said Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part 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
Benjamin Cook, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, is particularly described and
ascertained in and by the following statement thereof (that is to say):-
All argand burners hitherto made and used for the consumption of gas
have been drilled or perforated vertically, the effect of which is that the gas is
forced out through holes drilled or perforated at the top of the burner, and
consequently the flame rises perpendicularly.
Now my Invention consists in drilling or perforating Argand burners at an
angle instead of vertically, the advantage attending which is, that the gas
being forced through holes drilled at the sides of the burner, instead of through
holes drilled or perforated through the top of it, (which is the case where the
burner is drilled or perforated vertically,) passed into and through a larger
portion of atmospheric air, consumes of course a larger portion of the oxygen
in the air, and necessarily possesses a greater illuminating power," with the con-
sumption of a smaller quantity of gas. By these means combustion is ren-
dered perfect and complete, and all smoke is prevented.
In drilling or perforating. the holes through the sides of the burner I do not
confine myself to any one particular angle for the purpose, but take whatever
angle I may find most convenient and proper, whether it be at twenty, thirty,
or sixty degress.
In witness whereof, I, the said Benjamin Cook, have hereunto set my
hand and seal, this Second day of June, in the year of our Lord One
thousand eight hundred and thirty-eight.
