This Invention consists, -
:-
Firstly, in the construction of burners is such a manner as to cause a
current of air to impinge upon every part of a flame of gas or hydro-
carbon oil at the proper point or part of the above, the point of ignition
in a circular concentric or multiplied flat wick burner so as to secure the
most complete combustion of the carbon, and to obtain an increased
amount or power of light without a corresponding increase in the con-
sumption of the fluid employed for the purpose.
Secondly. In the means of maintaining a constant level of fluid at any
desirable height within the burner when applied to mechanical or
moderator lamps, by connecting to the feed pipe of the lamp an additional
upright pipe placed at a convenient distance therefrom, and into which
the fluid rises by its lower extremity, whilst its upper extremity is open.
This additional pipe rises to about the same height as the concentric
rings forming the burner, and inside this pipe I place a smaller pipe
which I call the overflow pipe, the lower extremity of which passes
through the bottom of the first pipe whilst its upper extremity is
pierced with one or more small holes through which the surplus liquid
descends.
Thirdly. In the employment of a platinum disc or a spherical
platinum sponge within a circular burner to cause the current of air
passing up through the centre of the burner to impinge upon the flame,
and on being heated to intensify the flame or light.
Fourthly. In the application of a stationary cylinder outside, and
surrounding a circular or concentric burner in such a manner as to
admit the passage of a current of air up through the space between this
cylinder and the burner, to impinge upon the outer part or periphery of
the flame, and upon which outer cylinder is an adjustable gallery or
holder for the glass chimney, by means of which gallery the chimney
may be raised or lowered to regulate the flame without the use of racks
and pinions, and without interfering with or in any way concealing any
part of the light.

page_text: In order that my Invention may be clearly understood, I will proceed
to describe it conjointly with the Figures of the accompanying Sheet of
Drawings, in which Figure 1 is a plan and Figure 2 an elevation in
section through A, A, Figure 1, of a lamp or burner composed of several
concentric wicks provided with its apparatus for maintaining a constant
level or supply of hydrocarbon oil to the same. Figure 3, a plan;
Figure 4, a sectional elevation; and Figure 5, an outside elevation of a
single circular wick burner.
First Improvement, Figures 1 and 2:-This improvement consists,
firstly, in providing the concentric wicks of a burner with an outer fixed
metallic tube rising above the extremities of the wicks to about the
same extent as the concentric tubes, serving as a separation between
the said wicks and the circular air passages, the upper extremity of the
said external tube being either itself turned slightly inwards towards the
centre of the lamp, or provided with a detached ring turned in the same
manner, and being susceptible of sliding up or down on the said outer
tube for the purpose of adjustment, if necessary; and, secondly, in pro-
viding a central button adjustable vertically, by means of which the two
currents of air (external and internal with regard to the wicks) are
conducted within the flame and not on the wicks, as usually practised,
for this latter mode is objectionable, in so far as the air thus introduced
cools the wicks, whilst by my new arrangement a more complete and
perfect combustion is obtained and a more brilliant light emitted; this
arrangement can also be applied to single wick circular burners. In
Figures 1 and 2, a represents the outer metallic tube, provided at its
upper extremity with a moveable and adjustable ring a¹, the upper
extremity of which latter is turned in towards the centre of the lamp, as
above stated; b is the central adjustable button, which can be raised or
lowered by the external button c, acting on the central rack d.
Second Improvement, Figures 1 and 2.-This improvement consists in
the means of maintaining a constant level of fluid at any desirable
height within the burner when applied to mechanical or moderator
lamps. For this purpose I connect to the feed pipe or box m of the
lamp a branch pipe g connected to a vertical pipe g¹, closed at its lower
extremity g² and open at its upper extremity 9³; within the pipe I place
concentrically a second smaller pipe h which I call the overflow pipe,
the lower extremity h³ of which is open, whilst in its upper extremity h²
I insert a small pipe i open at both extremities, and arranged so that it

page_text: in such a manner that it can be raised or lowered so to bring closer to
or further from the flame the current of air which rises from between
the upper surface of the gallery r and the under edge of the chimney p,
in the space left for the passage of this current, which is equal to the
thickness of the feet q, q, q, and preferably about one-eighth of an inch.
I also adapt this adjustable gallery or glass holder to a circular or argand
burner in conjunction with a disc of any desirable size or form, by means
of which adjustable gallery and disc an ordinary argand or a cylindrical
glass chimney may be employed to produce a tulip shaped or cylindrical
flame as may be best suited for parabolic or other reflectors.
Having thus explained the nature of my improvements and the best
means that I am acquainted with for putting the same into practice,
I claim,―
Firstly. The means and mechanism above specified under the first
head of my improvement for effecting a more complete combustion of
hydrocarbon oils.
Secondly. The means and mechanism for maintaining a constant
level of fluid to hydrocarbon lamps, as specified under the second head
of my improvements.
Thirdly. The employment of a platinum disc or a spherical platinum
sponge within a circular burner, as specified and for the purpose indicated
under the third head of my improvements.
Fourthly. The means and mechanism specified for conducting an
additional current of air to the burners, and of attaching and regulating
the glass chimney conjointly with a central disc or button, as indicated
under the fourth head of my improvements.
In witness whereof, I, the said Alexander Horace Brandon, have
hereunto set my hand and seal, the Twenty-seventh day of May,

page_text: NOW KNOW YE, that I, the said Alexander Horace Brandon, 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 Drawing
hercunto annexed, and to the letters and figures marked thereon (that
is to say) :-
.
This Invention consists, firstly, in the construction of burners in
such a manner as to cause a current of air to impinge upon every
part of a flame of gas or hydrocarbon oil at the proper point or
part of the above, the point of ignition in a circular concentric or
multiplied flat wick burner, so as to secure the most complete com-
bustion of the carbon, and to obtain an increased amount or power of
light without a corresponding increase in the consumption of the fluid
employed for the purpose.
Secondly. In the means of arresting the supply of fluid from the 1
reservoir to the burner when applied to gas or fountain lamps with the
reservoir situated above the burner (by means of a cock or other
appliance placed in any convenient part of the supply pipe).
Thirdly. In the means of maintaining a constant level of fluid at any
desirable height within the burner when applied to mechanical or 2
moderator lamps, by connecting to the feed pipe of the lamp an
additional upright pipe placed at a convenient distance therefrom, and
into which the fluid rises by its lower extremity, whilst its upper
extremity is open; this additional pipe rises to about the same height
as the concentric rings forming the burner, and inside this pipe I place 2
a smaller pipe, which I call the overflow pipe, the lower extremity of
which passes through the bottom of the first pipe, whilst its upper
extremity is pierced with one or more small holes through which the
surplus liquid descends.
Fourthly. In the employment of a platinum disc or a spherical 3
platinum sponge within a circular burner to cause the current of air
passing up through the centre of the burner to impinge upon the flame,
and on being heated to intensify the flame or light.
Fifthly. In the application of a stationary cylinder outside and
surrounding a circular or concentric burner in such a manner as to 3
admit the passage of a current of air up through the space between this

page_text: cylinder and the burner to impinge upon the outer part or periphery of
the flame, and upon which outer cylinder is an adjustable gallery or
holder for the glass chimney, by means of which gallery the chimney
may be raised or lowered to regulate the flame without the use of racks
and pinions, and without interfering with or in any way concealing any
part of the light.
Sixthly. In the construction of a cap or top of burner for two or more
flat wick (American) burners with a single aperture, and through which
all the flames are made to pass up with an unobstructed current of air
between each flame, and the direction of the flames made to converge
towards their upper points in order that a greater amount of oxygen may
be consumed, and a maximum amount of light obtained from the
material employed for this purpose.
In order that my Invention be clearly understood I will proceed
to describe it conjointly with the seven Figures of the accompanying
Sheet of Drawings, in which Fig. 1 is a plan, and Fig. 2 an elevation in
section through A, A, Fig. 1, of a lamp or burner composed of several
concentric wicks provided with its apparatus for maintaining a constant
level or supply of hydrocarbon oil to the same.
Fig. 3 a plan, Fig. 4 a sectional elevation, and Fig. 5 an outside
elevation of a single circular wick burner provided with the means of
arresting the supply of hydrocarbon oil, as stated under the second head
of my improvements.
And, Fig. 6 a plan, and Fig. 7 a sectional elevation of a burner
provided with two flat wicks, as stated under the sixth head of my
improvements.
First Improvement, Figures 1 and 2.-This improvement consists,
firstly, in providing the concentric wicks of a burner with an outer fixed
metallic tube rising above the extremities of the wicks to about the same
extent as the concentric tubes, serving as a separation between the said
wicks and the circular air passages, the upper extremity of the said
external tube being either itself turned slightly inwards towards the
centre of the lamp, or provided with a detached ring turned in the
same manner, and being susceptible of sliding up or down on the.
said outer tube, for the purpose of adjustment, if necessary; and
secondly, in providing a central button adjustable vertically, by means of

page_text: which the two currents of air (external and internal with regard to the
wicks) are conducted within the flame, and not on the wicks as usually
practised, for this latter mode is objectionable, in so far as the air thus
introduced cools the wicks, whilst by my new arrangement a more com-
plete and perfect combustion is obtained and a more brilliant light emitted;
this arrangement can also be applied to single wick circular burners.
In Figures 1 and 2 a represents the outer metallic tube, provided at
its upper extremity with a moveable and adjustable ring a', the upper
extremity of which latter is turned in towards the centre of the lamp,
as above stated; b is the central adjustable button, which can be raised
or lowered by the external button c acting on the central rack d.
Second Improvement, Figures 3, 4, and 5.-This improvement relates
to a means of arresting the supply of fluid from the reservoir to the
burner of gas or fountain lamps. I have represented it applied to a
single wick burner embodying my first improvement.
In these Figures e is the pipe through which the supply of hydro-
carbon reaches the burner f, and f¹ the cock whereby the same can be
regulated or completely cut off, as may be required.
Third Improvement, Figures 1 and 2.—This improvement consists in
the means of maintaining a constant level of fluid at any desirable
height within the burner when applied to mechanical or moderator
lamps. For this purpose I connect to the feed pipe or box m of the lamp
a branch pipe 9 connected to a vertical pipe 9', closed at its lower
extremity g², and open at its upper extremity g³; within the pipe I place
concentrically a second smaller pipe h, which I call the overflow pipe,
the lower extremity h' of which is open, whilst in its upper extremity h²
I insert a small pipe i open at both extremities, and arranged so that
it can be raised or lowered in the pipe h, either by being screwed within
the said pipe / or by sliding hermetically within the same; this said
pipe is pierced with a small hole k, and surmounted with a graduated
rod, the height of which above the upper extremity of the pipe g
indicates the position of the hole k, and consequently the level to
which the fluid rises in the wick. As it is readily seen by inspection of
Fig. 2, the fluid from the bow m rises directly to the wicks through
the small feed pipes o, and at the same time also through the pipes
ġ and g¹ from where it falls through the aperture and the overflow

page_text: pipe into any appropriate vessel; this part of the fluid is the excess,
or that which cannot be consumed by the lamp, thus on the one hand
the lamp is constantly supplied at any required height with the full
amount of fluid for its combustion, whilst the excess falls through my
constant level, and is returned to the feed without having been heated
by the lamp.
Fourth Improvement, Fig. 4.-This improvement consists in the
employment of a platinum disc or a spherical platinum sponge within a
circular burner to cause a current of air passing up through the centre
of the burner to impinge upon the flame, and on being heated to
intensify the flame or light. In this case I substitute to the central
button 6 a disc of platinum or preferably spongy platinum approaching
a spherical shape; the position and the diameter of these platinum
buttons remain the same, or nearly so, as the ordinary brass button
which they are intended to replace.
Fifth Improvement, Figures 1 and 2.-This improvement consists,
firstly, in a peculiar construction of parts, whereby an external current
of air is caused to rise between the chimney and the external cylinder
forming the burner, and brought to impinge upon the outer part or
circumference of the flame; and, secondly, in adapting on this said
external cylinder an adjustable gallery or holder for the support of the
ordinary glass chimney, by means of which adjustable gallery the
chimney may be raised or lowered so as to regulate the flame without
the use of racks and pinions, and also without interfering with or
in any case concealing any part of the light. p is the glass chimney
resting upon three feet q, q, q, soldered or otherwise attached on the
gallery or ring 7; s, 8, s, are three light springs serving to maintain
the chimney in place; the gallery or ring » fits tightly on the external
tube
a,
but in such a manner that it can be raised or lowered so to bring
closer to or further from the flame the current of air which rises from
between the upper surface of the gallery and the under edge of the
chimney in the space left for the passage of this current, which is
equal to the thickness of the fect q, q, q, and preferably about one-eighth
of an inch. I also adapt this adjustable gallery or glass holder to a
circular or argand burner in conjunction with a disc of any desirable
size or form, by means of which adjustable gallery and disc an ordinary
argand or a cylindrical glass chimney may be employed to produce a

page_text: tulip shaped or cylindrical flame, as may be best suited for parabolic or
other reflectors.
Sixth Improvement, Figures 6 and 7.-This improvement relates to a
peculiar construction of burner and cap, whereby two or more (American)
flat wicks can be caused to burn together under one cap. Figures 6
and 7 exemplify this improvement representing a double flat-wick lamp,
in which n, n, are the wick tubes; t, t, the pinions for raising and
lowering the same by means of external buttons in the usual manner;
n, the perforated basket, through which the air enters for feeding the
flame, and the cap, in which a single hole is cut for the passage of the
united two flames. It will easily be seen, without having recourse to
another Drawing, that a larger number of wicks can be arranged in
the same manner, so as to unite the flames through one single hole cut
in the cap.
Having thus explained the nature of my improvements, and the
best means that I am acquainted with for putting the same into practice
I claim,―
Firstly. The means and mechanism above specified under the first
head of my improvements for effecting a more complete combustion of
hydrocarbon oils.
Secondly. The means and mechanism specified under the second
head of my improvements for arresting partially or entirely the supply
of fluid to the burners of gas or fountain lamps with the reservoir
situated above the burner, as specified under the second head of my
improvements.
Thirdly. The means and mechanism for maintaining a constant level
of fluid to hydrocarbon lamps, as specified under the third head of my
improvements..
Fourthly. The employment of a platinum disc or a spherical
platinum sponge within a circular burner as specified, and for the a
purpose indicated under the fourth head of my improvements.
Fifthly. The means and mechanism specified for conducting an
additional current of air to the burners, and of attaching and regulating
the glass chimney conjointly with a central disc or button, as indicated
under the fifth head of my improvements.
