page_text: LETTERS PATENT to Marc Antoine François Mennons, of the British and
Foreign Patent Offices, 39, Rue de l'Echiquier, Paris, in the Empire
of France, for the Invention of "IMPROVEMENTS IN BURNERS FOR HEATING
BY GAS." A communication from Carsten Richard Meyn, residing. at
Carlshütte, Rendsburg, in the Duchy of Holstein.
PROVISIONAL SPECIFICATION left by the said Marc Autoine François
Mennons at the Office of the Commissioners of Patents, with his
Petition, on the 22nd February 1862.
I, MARC ANTOINE FRANÇOIS MENNONS, of the British and Foreign Påtent
Offices, 39, Rue de l'Echiquier, Paris, 'in the Empire of France, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN BURNERS FOR
HEATING BY GAS," to be as follows:-
The Invention communicated to me consists in an improved construction of
gas burner for general heating purposes, by means of which intense and
perfect combustion is obtained unaccompanied by the smoke, escapes, a
.and
other disadvantages inherent in such apparatus as at present arranged.
Figure 1 of the annexed Drawing represents in view a burner comprising
the present improvements; Figure 2 is a vertical section of the same.
A is a threaded metallic socket, which may be screwed to a pipe, pillar, or
[Price 8d.]

page_text: other setting, fitted at the top with a common burner B; C, C¹, is a tube
fixed to the socket A, and pierced with apertures for the admission of atmo-
spheric air. The lower part C¹ of this tube is provided with a lining of coarse
wire gauze (about 14 meshes to the inch) by which the air is divided and
.freed from foreign matters in its passage through the apertures above noted.
D is a sliding collar surrounding, the part C¹ of the tube C, and pierced to
correspond with the apertures of the latter. This collar serves to regulate the
admission of air by increasing or decreasing the area of the apertures
according to the requirements of the combustion. E is a small cone fitted
to the upper part of the tube Ċ by a bayonet or other suitable joint; F is a
cap of metallic gauze of about 25 meshes to the inch, adjusted in a metallic
setting, which is secured on the top of the tube C by means of the cone E;
Gis another conical tube formed of slightly oxidable metal or other suitable
matter set over the gauze cap F in the upper- part of the cone E, beyond
which it projects to the distance of about half an inch; H is a capsule of the
same material pierced at its centre with an orifice of about ths inch in
diameter so as to confine the line of combustion when the flame is reduced.
Figure 3 is a cross section of the sliding collar or air regulator D.
- Figure 4 is a vertical section of the cone G with its capsule H.
On using the apparatus constructed' as above, the air apertures of the
tube C¹ are closed by the regulator and the gas supply cock is turned on.
The gas being lighted will then produce an illuminating flame at the edge of
the line of combustion. To convert this illuminating into a heating flame,
the regulator is moved round until the quantity. of air admitted by the
apertures thus uncovered gives rise to a uniform and transparent light blue
tint. Should the yellow colour subsist at the tip of the flame when the
apertures are completely opened, the quantity and pressure of the gas should
be reduced by slightly closing the supply cock. The form, dimensions, and
general arrangement of different parts of the complete apparatus, as also the
number of burners may be varied according to circumstances.
.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Marc Antoine François Mennons, in the Great Seal Patent
Office on the 6th August 1862:
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of the British and Foreign Patent Offices,
39, Rue de l'Echiquier, Paris, in the Empire of France, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of February, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant,unto
me, the said Marc Antoine François Mennons, Her special licence that I, the
said Marc Antoine François Mennons, my executors, administrators, and
assigns, or such others as I, the said Marc. Antoine François Mennons, 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 BURNERS FOR
HEATING BY GAS," a communication from Carsten Richard Meyn, a
person resident at Carlshütte, Rendsburg, in the Duchy of Holstein,
upon the condition (amongst others) that I, the said Marc Antoine
François Mennons, my executors or administrators, by an instrument in
writing under, my, or their, or one of their hauds 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 Marc Antoine Francois Mennons, 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 Figures of the
accompanying Drawing and to the letters marked thereon, that is to say:
The Invention communicated to me consists in an improved.construction
of gas burner for general heating purposes, by means of which intense and
perfect combustion is obtained unaccompanied by the smoke, escapes, and
other disadvantages inherent to such apparatus, as hitherto arranged.
Figure 1 of the annexed Drawing represents in view a burner comprising
the present improvements; Figure.2 is a vertical section, of the same.
A is a threaded metallic socket, which may be screwed to, a pipe, pillar, or.
other setting, fitted at the top, with a common burner B; C, C', is a tube.
fixed to the socket A, and pierced with apertures for the admission of atmo-
spheric air. The lower part C¹ of this tube is provided with a lining of, coarse
wire gauze (about fourteen meshes to the inch) by which the air is, divided
and freed from foreign matters in its passage through the apertures above
noted.. D is a sliding collar, surrounding the part C' of the tube C, and pierced

page_text: to correspond with the apertures of the latter. This collar serves to regulate
the admission of air by increasing or decreasing the area of the apertures
according to the requirements of the combustion. E is a'small cone fitted to
the upper part of the tube C by a bayonet or other suitable joint; Fis a cap
of metallic gauze (of about 25 meshes to the inch) adjusted in a metallic
setting which is secured in position on the top of the tube C by means of the
cone E. This gauze cap should be of a conical, undulating, or otherwise
moulded form (not flat) so as to afford the necessary space for the passage of
the gases while adding to the energy of the draught. G is another conical
tube, formed of slightly oxidable metal or other suitable matter, set over the
gauze cap F in the upper part of the cone E, beyond which it projects to the
distance of about half an incli; H is a capsule of the same material, pierced
at its centre with an orifice of about three-eighths of au inch in diameter, so
as to confine the line of combustion when the flanie is reduced. The diameter
of this orifice may, of course, be varied according to the flame required.
Figure 3 is a cross section of the sliding collar or air regulatör D.
Figure 4 is a vertical section of the cone G with its capsule H.
On using the apparatus constructed as above, the air apertures of the tube C₁
are closed by the regulator,and the gas supply cock is turned on. The gas being
lighted will then produce an illuminating flame at the edge of the line of com-
bustion. To convert this illuminating into a heating flame the regulator is
moved round until the quantity of air admitted by the apertures thus uncovered
gives rise to a uniform and transparent light blue tint. Should the yellow
color subsist at the tip of the flamé "when the apertures are completely
opened, the quantity and pressure of the gas should be reduced by slightly
closing the supply cock.

"
Figure 5 represents in cross section' a six-jet burner with gas tubes of
different diameters at the point of combustion. E is 'à moveable plate by
which the position of the tubes is changed according as it may be required to
obtain three large or three small flames 'or the entire number'at once; D is
the air regulator.

Figure 6 represents the base plate A of the receiver C; with the air
apertures and regulator.
Figure 7 is a top view of the plate E, with the six combustion tubes
G and H.
"
Figure 8 is a top view of the receiver C with its apertures corresponding
with the gas tubes.
From the preceding examples it will be seen that the form;dimensions,and
general arrangement of the different parts of the complete apparatus; as also

page_text: the number of burners may be varied according to the intended application or
amount of heat required.
Having now described the nature of the said improvements, and the
manner of carrying them into effect, I would repeat in conclusion that I do not
confine myself to the precise detailsof construction and arrangement above laid
down,as these may obviously be modified without deviating from the principles
or main features of the Invention; I would on the other hand remark that I lay
no exclusive claim to the construction of burners provided with wire gauze or
analogous openworked diaphragms, such arrangements being already known
and employed under many forms differing more or less from the system above
described; but what I claim and desire to protect by the herein-before in
part recited Letters Patent is,-
1stly, the application to gas burners, for heating purposes, of a regulating
apparatus, substantially as above specified and shewn in C, D, Figs. 1, 2, 3,
5, 6, of the annexed Drawing, by means of which a due supply of atmospheric
air may be mingled with the gas,and its introduction controlled according to
the requirements of the combustion.
2dly, the application to such burners of a conical, undulating, or otherwise
indented or moulded cap or diaphragm of metallic gauze, in manner and for
the purpose substantially as herein set forth, and shewn in F, Figs. 2, 5, 7, of
the annexed Drawing.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereto set my hand and, seal, this Fourth day of August, in the
year of our Lord One thousand eight hundred and sixty-two.
M. F. MENNONS. (L.S.)
