page_text: LETTERS PATENT to Leon. de Pariente, of Paris, (France,) Gentleman, för
the Invention of "IMPROVEMENTS IN APPARATUS TO BE APPLIED TO GAS
BURNERS, WITH THE OBJECT OF INCREASING THE LIGHTING POWER OF THE GAS
FLAME." A communication.
Sealed the 18th March 1859, and dated the 21st September 1858.
PROVISIONAL SPECIFICATION left by the said Leon de Pariente at
the Office of the Commissioners of Patents, with his Petition,, on the
21st September 1858.
I, LEON DE PARIENTE, of Paris (France,) Gentleman, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS TO BE
APPLIED TO GAS BURNERS, WITH THE OBJECT OF INCREASING THE LIGHTING POWER
OF THE GAS FLAME," to be as follows:-
The apparatus consists of a platina or other metal, or other suitable body of
an annular or any other suitable shape, according to the nature of the burner,
which apparatus may be applied to gas burners of any description, and fixed
thereto in such manner as to be partly inserted in the unluminous or blue
portion of the gas flame, thereby beating and dividing that portion of the
flame, and allowing the atmospheric air to mix more completely with the gas,
so as to secure a more perfect combustion of this latter, and an increase of the
illuminating power of the flame.

by the said Leon de Pariente, in the. Great Seal Patent Office on the
21st March 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEON DE
PARIENTE, of Paris, France, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of September, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Leon de Pariente, Her special licence that I, the said Leon de
Pariente, my executors, administrators, and assigns, or such others as I, the
said Leon de Pariente, 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 "IM-
PROVEMENTS IN APPARATUS TO BE APPLIED TO GAS BURNERS, WITH THE OBJECT OF
INCREASING THE LIGHTING POWER OF THE GAS FLAME," a communication from a
foreigner now residing abroad, upon the condition (amongst others) that I, the
said Leon de Pariente, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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. Leon de Pariente, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:"
The Invention relates to the adaptation to gas burners of a peculiar
apparatus for the purpose of increasing the lighting or illuminating power of
the gas flame issuing from the burner, by dividing this latter, and causing an
introduction of air into the flame, thereby imparting a greater heat to the
lower or blue part of the flame, whereby the lighting effect of this latter part,
and consequently of the entire flame is increased, without increasing the con-
sumption of gas. The apparatus, which may be either moveable, or form one
solid body with the burner, may be applied to gas burners of any description;

page_text: but I prefer applying the same more particularly to the kind called bat's
wing and Manchester burners.

In the annexed Drawings, the Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, show various
views of Manchester burners; and the Figs. 10, 11, 12, of a bat's-wing
burner provided with the apparatus, which latter consists merely of a wire of
platinum, or other, suitable metal or material, to which wire any suitable shape
or configuration may be given, according to the shape and size of the burner;
and which wire may be fixed either directly to the burner, as shown in the
Figs. 1 to 9, or to a moveable ring, cap, or other. contrivance, as shown in
Figs. 10, 11, 12, for allowing of applying the same to the burner, or remove
it therefrom at pleasure. In the various Figures of the Drawings corre-
sponding parts are indicated by the same letters of reference.
Figure 1 is a front, Fig. 2 a side, and Fig. 3.a top view of a Manchester
burner provided with my apparatus. a is the wire, which is inserted with
both ends in a sort of shoulder or projecting part b, with which the top of the
burner c is provided, and which is flattened off on two opposite sides, as may
be seen from Fig. 3; the wire a may be round or flattened, and any suitable
shape given thereto, according to the nature of the burner, the amount of
pressure, and other circumstances. The Figures 1 to 10 show various forms
given to the wire a as applied to Manchester burners, in which the said wire
is fixed to the shoulder b, which latter forms a solid part of the burner; the
Figs. 10, 11, and 12, show the wire fixed with; both ends into a moveable
ring d, fitting round the upper part of a bat's-wing burner c¹; it must further
be remarked, that the wire ought to be situated in a transverse direction
to that of the flame, so as to cross this latter, as may be observed from Fig. 5,
in which Figure the dotted lines show the interior of a Manchester burner
with the holes e, by which the gas escapes from the burner. The wire a
requires to be situated in the interior of the lower or blue part of the flame,
which latter being thus divided, allows the atmospheric air to enter into and
properly mix with the gas, whereby the heat in that part of the flame will be
increased, and the particles of carbon contained in this blue part will become
sufficiently hot to impart an increased lighting power to this part of the flame.
It will be readily understood from what is just said, that the size, form, and
situation in the flame of the wire a must be modified according to the form
and nature of the burner, and the pressure and nature of the gas for which
the burner is to serve. It will also be readily understood, that the
apparatus may be applied to Argand or other gas burners, other than the
Manchester and bat's-wing burners shown in the Drawings.

page_text: I must further observe, that although I prefer applying only one wire to
each burner, each of them may be provided with two or more wires situated
in suitable positions, and crossing the gas flame at different heights.
Having thus described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe, in conclusion, that I do not confine or restrict
myself to the exact forms or shapes, or precise details of the arrangements
above described, nor to any particular description of burner to which the
apparatus may be applied, as many variations may be made in the arrangement
of the apparatus without deviating from the principles or main features of the
-said Invention; but what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part recited
Letters Patent, is, applying to gas burners of any description, and more par-
ticularly to the kind called Manchester and bat's-wing burners, an apparatus
consisting chiefly of one or more wires of platinum, or other suitable metal or
material, inserted in such manner in the gas flame issuing from the burner, as
properly to divide the said flame, thereby allowing a better introduction of
atmospheric air into the same, for the effect of increasing its illuminating
power.
In witness whereof, I, the said Leon de Pariente, have hereunto set
my hand and seal, this Eighteenth day of March, One thousand
eight hundred and fifty-nine.
Witness,
J. SOUTH.
