Year: 1863

page_text: LETTERS PATENT to Henri Adrien Bonneville, Patent Agent, of the
British and Foreign Patent Offices, 24, Rue du Mont Thabor, Paris, in
the Empire of France, for the Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF GAS BURNERS."-A communication by Theodore Berents,
Manufacturer, residing at Maestricht, in the Kingdom of Belgium.
Sealed the 2nd October 1863, and dated the 15th April 1863.
PROVISIONAL SPECIFICATION left by the said Henri Adrian Bonneville
at the Office of the Commissioners of Patents, with his Petition, on
the 15th April 1863.
I, HENRI ADRIEN BONNEVILLE, Patent Agent, of the British and Foreign
Patent Offices, 24, Rue du Mont Thabor, Paris, in the Empire of France,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF GAS BURNERS," a communication from Theodore Berents,
Manufacturer, a person residing at Maestricht, in the Kingdom of Belgium,
to be as follows:-
The object of this Invention is to increase the illuminating power of gas,
in allowing by means of division freer contact with the external air than is
permitted by the ordinary burners.
The Figures of the annexed Drawing, in which similar letters of reference
indicate similar parts, represent Fig. 1 a side view, and Fig. 2 a front view in
profile, of a burner made according to the improved plan.
A is a reservoir, in which the gas enters from the tube C, and of which the

page_text: upper part B is pierced with a number of small holes for the passage of the
gas, the number of which may be varied at pleasure; C is a bent tube
which conducts the gas into the reservoir A. The reservoir A is screwed at
the joint D to its bent support E, so that it may be removed for cleaning.
This burner may be made in brass or any other suitable metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henri Adrien Bonneville in the Great Seal Patent Office on
the 14th October 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, Patent Agent, of the British and Foreign Patent Offices,
24, Rue du Mont Thabor, Paris, in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of April, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Пer heirs and successors, give and grant unto me,
the said Henri Adrien Bonneville, Her special licence that I, the said Henri
Adrien Bonneville, my executors, administrators, and assigns, or such others
as I, the said Henri Adrien Bonneville, 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 THE CONSTRUCTION OF GAS BURNERS," com-
municated to me by Theodore Berents, Manufacturer, of Maestricht, in the
Kingdom of Belgium, upon the condition (amongst others) that I, the said
Henri Adrien Bonneville, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should parti-
cularly 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 Henri Adrien Bonneville, 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, that is to say:-
The object of this Invention is to augment the lighting power of gas by

page_text: dividing it as much as possible, so as to place it in contact with the atmo-
spheric air. This principle allows of regulating the flow of the gas, and of
burning it completely without waste, as it flows gradually and according to
the consumption without pressure.
The Figures of the accompanying Drawing, in which similar parts aro
represented by the same letters of reference, represent Fig. 1 a side view and
Fig. 2 a front view of a burner constructed on this principle.
A is a reservoir in which the gas arrives, and the upper part B of which is
pierced with a larger or smaller number of holes in a straight line, by which
the gas flows for combustion; C is an elbowed tube, the upper extremity of
which is provided with two small holes by which the gas flows, and which
serve for regulating its supply, so that the pressure of the gas in the feeding
tube does not operate on the gas accumulated in the reservoir A; the gas,
therefore, only escapes according as it is burned; D is a screw joint, which
facilitates the cleaning of the inside of the reservoir A or of the feeding tube.
All the above described parts may be made of brass, or any other suitable
metal or material.
To increase the lighting power of the gas, and render the flame steady, a
glass or chimney of an oval form, represented in Fig. 3, the upper part of
which is slightly contracted, may be employed. The reservoir A having an
oblong form, the sides of glasses of the described shape are at equal distances
from the flame, and facilitate the combustion.
Having thus described the nature of the said Invention, and the manner in
which it is to be performed, I wish it to be understood that I do not confine
myself to the precise details above given, which may be modified without
changing the principle of the said Invention; but what I claim is, the con-
struction of gas burners by means of which the combustion of the gas
operates without pressure by the holes of a reservoir placed above the tube,
which regulates the supply, the whole substantially as above described and
represented in the Figures of the accompanying Drawing.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Twelfth day of October, in the year of
our Lord One thousand eight hundred and sixty-three.
H. BONNEVILLE. (L.S.)
