Year: 1852

page_text: LETTERS PATENT to Francis Warren, of 16, Millbank Street, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN
GAS BURNERS"
Sealed the 12th January 1853, and dated the 6th October 1852.
PROVISIONAL SPECIFICATION left by the said Francis Warren
at the Office of the Commissioners of Patents, with his Petition,
on the 6th October 1852.
I, FRANCIS WARREN, of 16, Millbank Street, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN GAS BURNERS" to be as follows:-
This Invention consists of applying to argand, fishtail, batswing, or
other form of burner a wire or wires to divide the flame, and be kept
heated by it by reason of the wire or wires being within the flame,
thereby obtaining more complete combustion of the gas.

filed by the said Francis Warren in the Great Seal Patent Office,
on the 6th April 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I.
FRANCIS WARREN, of 16, Millbank Street, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date, the Sixth day of October, in the year of
our Lord One thousand eight hundred and fifty-two, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Francis Warren, Her special licence
that I, the said Francis Warren, my executors, administrators, and
assigns, or such others as I, the said Francis Warren, 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, 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 I, the said
Francis Warren, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said In-
vention, 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 Francis Warren, 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 thereof (that is to say):
My Invention consists of applying to argand, fishtail, batswing, or
other form of burner a wire or wires to divide the flame, and be kept
heated by it by reason of the wire or wires being within the flame,
thereby obtaining more complete combustion of the gas. And in order
that the Invention may be more fully understood, and readily carried
into effect, I will proceed to describe the means pursued by me.

page_text: DESCRIPTION OF THE DRAWING.
Figure 1, shews an argand burner; Figure 2, shews a fishtail
burner, and Figure 3, a batswing burner, to each of which is applied a
wire according to my Invention, and as is indicated by red lines, but
more than one wire may be so applied to a burner. The ends of the
wires enter sockets on each side of the burners, by which means the
wires can be readily applied and removed, the holes in the sockets
being formed or drilled in such manner as readily to receive the ends
of the wires, and to allow them to slip or pass freely therein; and as
there is elasticity in the wire, that portion which crosses through the
frame may be placed higher or lower by forcing the ends of the wire
less or more into the sockets, or the sockets may be made separate from
the burners, and have feunale screws formed therein suitable to screw
into male screws formed on the outsides of the burners, by which means
the position of the wires in the flaines may be adjusted by screwing the
sockets higher or lower on to the male screw on the outside of a burner.
I would remark that I have found that the above described mode of
applying wires to the flames of argand, fishtail, batswing, and such
like gas burners is most advantageous when not burning gas from
cannel coal.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would remark that I have been
informed and believe that it has before been proposed to apply a some-
what similar wire or instrument to a jet gas burner. I do not there-
fore claim the same. But what I claim is, the application as herein
described of a wire or wires to argand, fishtail, batswing, and such
like gas burners..
In witness whereof, I, the said Francis Warren, have hereunto
set my hand and seal, this Thirtieth day of March, One thousand
icht hundred and fifty-three
Witness,
S. CARPMAEL.
FRANCIS WARREN. (L.s.)
