IMPROVEMENTS IN GAS BURNERS
Year: 1858

page_text: LETTERS PATENT to William Oldfield, of Skipton, in the County, of York,.
Optician, and Thomas Ogden Dixon, of Steeton, in the same County,
Manufacturer, for the Invention of "IMPROVEMENTS IN GAS BURNERS."
Sealed the 27th July 1858, and dated the 30th March 1858.
PROVISIONAL SPECIFICATION left by the said William Oldfield and
Thomas Ogden Dixon at the Office of the Commissioners of Patents,
with their Petition, on the 30th March 1858.
We, WILLIAM OLDFIELD, of Skipton, in the County of York, Optician, and
THOMAS OGDEN DIXON, of Steeton, in the same County, Manufacturer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN GAS
BURNERS," to be as follows:-
The improvements relate to the application over the slits or perforations of
gas burners of a cap or cover, forming a chamber with a slit or openings
therein, so that the gas to be consumed passes from the first opening or
openings into a chamber, thence through a slit or openings therein for
ignition. We apply the opening or openings in the cap or cover so that the
direction of the flame thereby produced may be at an angle to that which
would be produced by the passing of the gas through the first slit or openings,
and we form the second slit or openings. of a considerably larger area than
the first.

Seal Patent Office on the 29th September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
OLDFIELD, of Skipton, in the County of York, Optician, and THOMAS OGDEN
DIXON, of Steeton, in the same County, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of March, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said William Oldfield and Thomas Ogden Dixon, Her special
licence that we, the said William Oldfield and Thomas Ogden Dixon, our
executors, administrators, and assigns, or such others as we, the said William
Oldfield and Thomas Ogden Dixon, our executors, administrators, and assigns,.
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN GAS BURNERS," upon the condition (amongst others) that
we, the said William Oldfield and Thomas Ogden Dixon, our executors or
administrators, by an instrument in writing under our or their hands and
seals, or under the hand and seal of one of us or them, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that we, the said William Oldfield and Thomas Ogden
Dixon, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say:
The improvements relate to the application over the slits or perforations
of gas burners of a cap or cover, forming a chamber with a slit or openings
therein, so that the gas to be consumed passes from the first opening or
openings into a chamber, thence through a slit or openings therein for
ignition. We apply the opening or openings in the cap or cover so that the
direction of the flame thereby produced may be at an angle to that which
would be produced by the passing of the gas through the first slit or openings,

page_text: and we form the second slit or openings of a considerably larger area than
the first.
But that the nature of these our improvements, and the best means we are
acquainted with for carrying the same into effect, may be fully understood, we
will proceed to describe the Drawings annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews an external view, and Figure 2 a vertical section, of an
arrangement of burner according to our improvements; Figure 3 is a sec-
tional plan through 1, 1, of Figures 1 and 2; and Figure 4, a plan looking
down upon the burner; Figures 5 and 6 shew the parts separately on a larger
scale. a is that part of the burner through the perforations b, b, of which the
gas issues into the chamber formed by the cap or cover c, in the upper part
of which is formed the slit d. We would state it is important that the gas
issuing from the apertures b, b, strike against the sides of the chamber c, c, and
that the slit or openings in the upper part of the chamber c, where ignition
takes place, be across or at an angle to and of at least three or four times the
area of the openings in the upper part of a. Figures 7 and 8 show a modi-
fication of the above, in which the apertures b in the part a cross each other
as in the ordinary fish-tail burner. By these adaptations the gas becomes
attenuated, and a vastly superior flame is produced, with considerable economy
in the consumption of gas.
Having thus stated the nature of our said Invention, and in what manner
the same is carried into effect, we would have it understood that we do not
confine ourselves to the precise details shown and described, so long as the
slits or openings for the escape of the gas from the upper part of chamber or
cover c is at an angle to or across those by which the gas escapes from
passages 6, substantially as explained.
In witness whereof, we, the said William Oldfield and Thomas Ogden
Dixon, have hereunto set our hands and seals, this Twentieth day of
September, in the year of our Lord One thousand eight hundred and
fifty-eight
Witness,
JOSEPH WADE, Steeton.
