page_text: LETTERS PATENT to William Edward Gedge, of the Firm of John
Gedge and Son, of No. 11, Wellington Street, Strand, in the
County of Middlesex, Patent Agent, for the Invention of "AN
IMPROVED GAS BURNER."-A communication from abroad by Joseph
Rousselot, of Paris, France, Manufacturer of Gas Apparatus.
Sealed the 20th April 1869, and dated the 26th October 1868.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition, on
the 26th October 1868.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son, of
No. 11, Wellington Street, Strand, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "AN
IMPROVED GAS BURNER," a communication to me from abroad by Joseph
Roussclot, of Paris, France, Manufacturer of Gas Apparatus, to be as
follows:-
Fig. No. 1 of the accompanying Sheet of Drawing forming part of
this my Provisional Specification shows the improved burner the subject

page_text: of this Invention complete as fixed, displaying its novel shape; Fig. No. 2
shows the naked burner or nipple, A indicating the opening in the
middle by which the gas passes to the interior of the burner and thence
to the openings B, where it is consumed. The four openings at C
indicate outlets for air supplied by one or several conduits beneath
or at the side of the burner; these holes may vary in size to suit
requirement. This nipple may be of any desired shape, and be made,
together with its fittings of any suitable metal or material.
The difference between this burner and other burners of this kind
consists in its receiving gas through the middle and air from beneath or at
the sides with the object of altogether doing away with the branches and
the solderings or brazings which considerably increase the cost of manu-
facture, especially if the largest possible holes or circular outlets, more or
less broad, may be pierced in the burner according to the degree of light
required. The practical result of this new method is that the gas arrives
at the orifice of the burner without pressure, the flame is no longer
subject to wavering, and the blue which is an obstacle to the brilliancy
of the light. disappears by reason of the total consumption of the gas.
The novel shape of burner and system of gas and air supply consti-
tuting this Invention may be applied to every kind of gas burner, and
this Invention may be clearly defined as a direct gas supply or as a
supply of air from the sides or beneath the burner for the interior of the
nipple.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Gedge in the Great Scal Patent
Office on the 23rd April 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 11,
Wellington Street, Strand, in the County of Middlesex, Patent Agent,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of October, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-

page_text: second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Edward Gedge, Her special licence
that I, the said William Edward Gedge, my executors, administrators,
and assigns, or such others as I, the said William Edward Gedge, my
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, usc,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN
IMPROVED GAS BURNER," a communication to me from abroad by Joseph
Roussclot, of Paris, France, Manufacturer of Gas Apparatus, upon the
condition, amongst others, that I, the said William Edward Gedge, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and scals, 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 I, the said William Edward Gedge, do hereby
declare the nature, of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the accom-
panying Sheet of Drawing forming part of this Specification, and to the
figures and letters of reference marked thereon:
Fig. 1 of the Drawing represents the improved burner, the subject of
this Invention, complete as fixed, displaying its novel shape; Fig. 2, the
naked burner or nipple, A indicating the opening in the middle by
which the gas passes to the interior of the burner and thence to the
openings B, where it is consumed. The four openings at C indicate
outlets for air supplied by one or several conduits beneath or at the side
of the burner; these holes may vary in size to suit requirement.
Fig. 3 is a plan, and Figs. 4 and 5 are sections of another shape of
burner on the same principle. This burner may be of any desired
shape, and be made, together with its fittings, of any suitable metal or
material.
The difference between this burner and other burners of this kind
consists in its receiving gas through the middle and air from beneath or

page_text: at the sides with the object of altogether doing away with the branches
and the solderings or brazings which considerably increase the cost of
manufacture, especially if the largest possible holes or circular outlets,
more or less broad, may be pierced in the burner according to the degree
of light required. The practical result of this new method is that the
gas arrives at the orifice of the burner without pressure, the flame is no
longer subject to wavering, and the blue which is an obstacle to the
brilliancy of the light disappears by means of the total consumption of
the gas.
The novel shape of burner and system of gas and air supply con-
stituting this Invention may be applied to every kind of gas burner,
and this Invention may be clearly defined as a direct gas supply or
as a supply of air from the sides or beneath the burner for the interior of
the nipple.
In witness whereof, I, the said William Edward Gedge, have here-
unto set my hand and seal, this Twenty-third day of April,
in the year of our Lord One thousand eight hundred and sixty-
nine.
