PROVISIONAL SPECIFICATION.
Improvements in Burners for Incandescent Gas Light.
I, RICHARD VIOLET of No. 20 Cuvrystrasse, Berlin S.O. in the Empire
of Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in burners for incandescent gas light, and
the object of said improvements is to obtain not only the highest possible effect of
illuminating power, but also the greatest economy of gas.
In Bunsen burners generally employed for producing incandescent gas light, an
important feature hitherto has been greatly neglected, namely, that of producing
the greatest possible heat, and, in consequence, neither the lighting power, nor the
economy of gas obtained have reached that degree, to which they are capable of
being developed. The object of my invention, accordingly, is, in the first place,
to create, in a burner of the class described, as high a degree of heat, as may be
practically attained, and for this purpose, it is above all, necessary to effect
a perfect and most intimate mixture of the rising current of atmospheric air with
the gas to be consumed, whereby a complete combustion of all combustible matter
contained in the gas is obtained. And, further, it, is of importance to accelerate
the upward movement of the mixture of gas and atmospheric air within the burner
tube, whereby the flame will burn with a higher pressure than actually exists in the
gas feed pipes.
To obtain the said objects in view, I have constructed an improved burner, which
is hereinafter more fully described.
On a Bunsen burner of usual and well-known construction a tube is mounted,
which tube may equally serve to support a lamp chimney fitting into a gallery
carried by said tube. Within the upper end of said tube, a box or casing is secured
by screwing the same with its threaded periphery into a tapped portion of the said
tube. The bottom of the said box or casing is perforated, and its top is covered
by a sieve.
In the centre of said casing, a pin or rod is secured by a nut to the
bottom of the casing. To the lower portion of said pin, one, two or more
fan-wheels are secured and adjusted by a counter nut in their proper position.
The working effect of the burner as described, is as follows:-
The gas issuing from the nozzle carries along by suction the atmospheric air
entering through suitable apertures, and, in passing upwards, the mixture of gas
and air encounters one of the fan-wheels, whereby the said mixture is forced to
assume a rotary motion, which serves to effect a more intimate mixture of the gas
and air. After passing the fan-wheel, the said mixture must pass the other
fan-wheel, the wings of which have a position opposite to those of the first wheel.
The rising current, thereby, is forced to take a direction opposite to that followed
before, and owing to this reversed rotary motion of the rising current, the mixture
of gas and air is made as perfect and intimate, as practically possible.
When the flame has been ignited, the amount of gas and air consumed and the
increasing heat act to accelerate the rising current and the fan-wheels begin
to effect a suction by means of which the upward speed of the current of gas and
air is further increased and the pressure in the flame raised to a higher degree.
Owing to this and to the complete intimate mixture of the gas and air. as
described, the useful effect, as a matter of course, is raised to the highest possible
point.

page_text: The incandescent body, preferably in the known shape of a hose, is hung from a
tube mounted on the pin, said tube being forked at its upper end, the extensions of
the forked portion serving as a means by which the said tube may be taken hold of
when mounting the same.
The said pin is slotted to permit the tube to be adjusted by friction against the
surface at any desired position, in order to properly adjust the incandescent body,
as desired.
To prevent the said incandescent body from being displaced in a lateral direction,
I secure the said body by means of a hinged ring secured to the tube which carries
the casing by means of a lug and the pivot of the hinge. The said ring may be
locked against accidental opening by a suitable clasp.
To mount the incandescent body by the aid of said ring I proceed as follows:-
Before placing the incandescent body in position I open the hinged ring and then
mount the tube carrying the incandescent body on the pin or rod with the lower
edge of said body approaching the sieve. Then I close the said ring around the
lower part of the incandescent body and thereby secure the same against changing
its position in a lateral direction.
Instead of using an open, hinged ring, as described, I may as well employ a closed
ring, which is fitted on the tube, either before or after mounting an incandescent
body, whereby the said body is equally secured in its position against lateral
displacement.

Improvements in Burners for Incandescent Gas Light.
1, RICHARD VIOLET of No. 20 Cuvrystrasse, Berlin S.O. in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to improvements in burners for incandescent gas light, and
the object of said improvements is to obtain not only the highest possible effect of
illuminating power, but also the greatest economy of gas.
In Bunsen burners generally employed for producing incandescent gas light, an
important feature hitherto has been greatly neglected, namely, that of producing
the greatest possible heat, and, in consequence, neither the lighting power, nor the
economy of gas obtained have reached that degree to which they are capable of
being developed. The object of my invention, accordingly, is, in the first place, to
create, in a burner of the class described, as high a degree of heat as may be
practically attained, and for this purpose, it is above all necessary to operate a
perfect and most intimate mixture of the rising current of atmospheric air with the
gas to be consumed whereby a complete combustion of all combustible matter
contained in the gas is obtained. And, further, it is of importance to accelerate
the upward movement of the mixture of gas and atmospheric air within the burner
tube whereby the flame will burn with a higher pressure than actually exists in the
gas feed pipes.
To obtain the said objects in view, I have constructed an improved burner which
is hereinafter more fully described with reference to the accompanying drawings,
in which,
Figure 1 is a vertical section of a burner embodying my invention, and
Figure 2, a plan view of the fan wheel.
On a Bunsen burner a of usual and well known construction, a tube b is

page_text: mounted, which tube b may equally serve to support a lamp chimney fitting into a
gallery carried by said tube b. Within the enlarged upper end of said tube 6 a box.
or casing c is secured by screwing the same with its threaded periphery into a
tapped portion of the said tube b. Or the tube b may have a threaded periphery
and the casing c screwed over it. The bottom of the said box or casing c is
perforated as clearly shown and its top is covered by a sieve f. In the centre of
said casing c, a pin or rod g is held or secured through the bottom and top of the
box by a nut or other suitable fastening device. To the lower portion of said
pin g and inside the box or casing c, one two or more fan wheels d d' are mounted
and adjusted in their proper position to each other.
The working effect of the burner as described is as follows:-
The gas issuing from the nozzle carries along by suction the atmospheric air
entering through the apertures m, and in passing upwards, the mixture of gas and
air encounters the fan wheel d¹ whereby the said mixture is forced to assume a
rotary motion which serves to effect a more intimate mixture of the gas and air..
If another fan wheel d is applied, the said mixture of gas and air in its upward
flow must pass the other fan wheel too, the wings of which have a position opposite
to those of the lower wheel d¹. The rising current, thereby, is forced to take a
direction opposite to that followed before, and owing to this reversed rotary motion
of the rising current, the mixture of gas and air made as perfect and intimate,.
as practically possible. Additional fan-wheels may be employed, but in practice
it has been found sufficient to employ one or two fan-wheels of the kind
described.
When the flame has been ignited, the amount of gas and air consumed and the
increasing heat act to accelerate the rising current and the fan-wheel or wheels
begin to effect a suction by means of which the upward speed of the current of gas
and air is further increased and the pressure in the flame raised to a higher degree..
Owing to this pressure and to the complete, intimate mixture of the gas and air, as
described, the useful effect of the burner as a matter of course, is raised to the
highest possible point.
The incandescent body k, preferably in the known shape of a hose, is hung to
the tube i, carried by the pin g, and forked at its upper end, the extensions of the
forked portion serving as a means by which the said tube i may be held when
mounting the same.
The said pin g is slotted to permit the tube i to be adjusted by friction against
the surface at any desired position, in order to properly adjust. the incandescent
body k, as desired.
To prevent the said incandescent body from being displaced in a lateral direction,
I secure the said body k by means of a ring h, secured to the tube b. The said
ring may be open and hinged to a lug n of the tube b and it may be locked
against accidental opening by a suitable clasp.
In mounting the incandescent body by the aid of said ring, I proceed as
follows:
Before placing the incandescent body in position I open the hinged ring ḥ, and
mount the tube i on the pin g, the lower edge of the incandescent body carried by
the tube i, approaches the sieve f. Then I close the said ring around the lower
part of the incandescent body and thereby secure the same against changing its
position in a lateral direction.
Instead of using an open, hinged ring, as described, I may as well employ a
closed ring, which fits over the tube b, and holds the lower end of the incandescent
body securely around the tube 6 and prevents its lateral displacement.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a Bunsen-burner for incandescent gas-light: the combination, with the
burner, of a box or casing having a perforated bottom and sieve top, a pin centrally:

page_text: traversing said box or casing, and a fan-wheel or wheels carried by said pin,
substantially as hereinbefore described and shown on the accompanying drawing.
2. In a Bunsen-burner for incandescent gas-light: the combination, with the
burner tube, of a box or casing having a perforated bottom and a sieve top, a tube
carried by said pin to hold the incandescent body, a ring to secure the lower end of
the incandescent body against lateral displacement, and a fan-wheel or wheels
arranged inside the said box or casing, substantially as described.
