IMPROVEMENTS IN GAS BURNERS
Year: 1874

page_text: LETTERS PATENT to Corneille Joseph Tackels, of No. 50, Rue
Gaucheret, in the City of Brussels, in the Kingdom of Belgium,
Captain of Infantry, for the Invention of "IMPROVEMENTS IN GAS
BURNERS."
PROVISIONAL SPECIFICATION left by the said Corneille Joseph Tackels
at the Office of the Commissioners of Patents, with his Petition,
on the 26th June 1874.
I, CORNEILLE JOSEPH TACKELS, of No. 50; Rue Gaucheret, in the City
of Brussels, in the Kingdom of Belgium, Captain of Infantry, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN GAS
BURNERS," to be as follows:-
The object of this Invention is to moderate and regulate the supply
of gas used for lighting purposes; and the apparatus is composed of
three principal parts, that is to say :—
First. A cap or cover provided with one hole, and to which may

page_text: be attached, either the gas burner or the piece which carries
same.
Secondly. An obturator, the stem of which is tubular and has a screw
thread and longitudinal or oblique slits or openings thereon. The head
of the tubular screw is in the form of a thumbscrew. .
Thirdly. A mushroom-shaped piece, the upper part of which carries
the obturator, and the lower part screws on to the supply tube.
This mushroom may be conical with four vertical

grooves.
por-
The cone
forated, and the hydrocarbon gas passes through the same.
has a cover which acts as a moderator or regulator and prevents any
irregular pressure at the gasometer from being felt. The gas issues
from under the cover by the groves or slits in the cone and flows into
the cap, at the bottom of which are three circular indentations through
which the gas is obliged to pass, when by too great a pressure the cover
is raised and the ordinary passage is obstructed.
On the before-mentioned cap is screwed a gas burner of a cylindro-
ogival form, the top of which resembles a large thimble, in which is a
slit. A space is provided which constitutes a condensing receiver, with
the sides of which the gas comes in contact on issuing from the
openings, forms cross currents, and is impelled by centrifugal force
towards the burner..
i
The hydrocarbon gas is purified, and any irregular pressure at the
gasometer corrected. The gas arrives slowly and regularly towards the
orifice at which it is consumed under a very slight pressure, which
imparts to the flame steadiness and a regular form, and increases the
illuminating power, whilst the smoke and noxious emanations from the
hydrocarbon are also got rid of, and a large saving varying from 35
to 50 p' c. in the gas consumed is effected.
The obturator with its longitudinal or oblique slits receives the gas
through the tubular screen in which is placed a stopper or valve with
an obturating shoulder. The gas which escapes is compelled to pass
through the regulating openings. It is by means of these openings that
the consumption of gas is regulated, and also the height of flame for
the lights in manufactories, according to the number of stories to be
supplied;..

kinds of burners, whether placed horizontally or vertically.
In applying a moderator or regulator to each burner between the
cock and the piece carrying the burner or directly on the cock, the
object is not only to effect a saving but to prevent the emanations so
hurtful in schools and large meetings or assemblies of persons, where a
wholesome sanitary atmosphere is of primary importance.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Corneille Joseph Tackels in the Great Seal Patent
Office on the 26th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, 'CORNEILLE
JOSEPH TACKELS, of 50, Rue Gaucheret, in the City of Brussels, in the
Kingdom of Belgium, Captain of Infantry, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of June, in the year
of our Lord One thousand cight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Corneille Joseph Tackels, Her
special licence that I, the said Corneille Joseph Tackels, my executors,
administrators, and assigns, or such others as I, the said Corneille
Joseph Tackels, 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 Corneille Joseph Tackels, 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 imme-
diately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Corneille Joseph Tackels, do hereby
declare the nature of my 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 annexed.
Drawings, and to the figures and letters marked thereon, that is to
say :-
The object of my said Invention is to moderate and regulate the
supply of gas used for purposes of illumination.
The apparatus by means of which this object is effected is composed
of three several parts, that is to say :-
First. A cap or cover provided with one hole, to which may
be attached either the gas burner or the picce which receives the
same.
1
Secondly. An obturator, the stem of which is tubular and having a
screw thread, and longitudinal or oblique slits or "openings therein. 1
The head of the tubular screw is in the form of a thumbscrew.
Thirdly. A mushroom-shaped piece, the upper part of which carries
the obturator, whilst the lower part screws on to the supply tube.
This mushroom-shaped piece is of a conical form with four vertical
grooves, and being perforated, and the hydrocarbon gas passes through 2
the same. The cone is provided with a cover which acts as a moderator
or regulator, and prevents any irregular pressure at the gasometer or
source of supply from being felt. The gas issues from under the cover
by the grooves or slits in the cone and flows into the cap, at the bottom of
which are three circular indentations through which the gas is obliged 2
to pass, when by too great a pressure the cover is raised and the ordinary
passage is obstructed.
On the before-mentioned cap is screwed a gas burner of a cylindrical
"ogival" form, the top of which resembles a large thimble in which is
a slit. A space is provided which constitutes a condensing receiver, 3
with the sides of which the gas comes in contact on issuing from the
openings, and thus forming a cross current is impelled by centrifugal
force towards the burner.
By means of the before-described arrangements the hydrocarbon gas
is purified, and any irregular pressure at the gasometer or source of 3

page_text: supply arrested.
The gas arrives slowly and regularly towards the
orifice at which it is consumed under a very light pressure, whereby
steadiness and a regular form are imparted to the flame, and the
illuminating power thereof increased; whilst the smoke and noxious
5 emanations from the hydrocarbon gas are also got rid of, and a large
saving varying from 35 to 50 per cent. in the gas consumed, is
attained.
The obturator with its longitudinal or oblique slits receives the gas
through the tubular screw, in which is placed a stopper or valve with
an obturating, shoulder. The gas which escapes is compelled to pass
through the regulating openings. It is by means of these openings that
the consumption of gas and the height of flame for illuminating
purposes in manufactories and other large buildings, according to the
number of stories to be supplied, is regulated.
The lower portion of the mushroom-shaped part is applicable to all
kinds of burners, whether placed horizontally or vertically.
In applying a moderator or regulator to each burner between the
cock and the piece carrying the burner or directly on the cock, the
object is not only to effect a saving but also to prevent the emanations
from the gas which are so unpleasant and injurious in schools and at
large meetings or assemblages of persons, in which cases a wholesome
atmosphere is of primary importance.
I will now proceed to refer to the annexed Drawings, from which
the nature of my said Invention will be more clearly understood.
Figures 1 and 2 are transverse sections, and Figure 3, an external
elevation of the apparatus. The other Figures represent the parts
detached.
.
a is the cap or cover; 6 is the supply tube; c is the head of the
tubular screw formed in the obturator; d is the conical mushroom-
shaped piece; and e is the moderating cover for the same.
The space
which acts as the condensing receiver, as before mentioned, is indicated
at a¹.
Having thus declared and ascertained the nature of my said In-
vention, and in what manner the same is to be performed, I would
observe in conclusion, that what I consider novel and original, and

page_text: 'therefore claim as constituting the Invention secured to me by the said
herein-before in part recited Letters Patent is, the combination of parts
and mechanism, substantially as and for the purposes herein-before
described and set forth.
In witness whereof, I, the said Corneille. Joseph Tackels, have
hereunto set my hand and seal, this Twenty-third day of
December, in the year of our Lord One thousand eight hundred
and seventy-four.
