Improvements in, and in the Manufacture of, Burners for
Incandescent Gas Lighting.
I, JOHN WILSON, of 16, George Road, Edgbaston, in the City of Birmingham,
Dispensing Chemist do hereby declare the nature of this invention to be as
follows:
This invention relates to atmospheric burners for incandescent lamps, and
consists, in one part, in a new construction of burner, and in another part, to an
economical method of manufacturing the same.
The burner consists of a double coned body part with the narrow ends of the
cones coming together and forming a choke or waist alike unto the waist of an
ordinary spool or reel, and each body part is made up of attachable sections with
the choked tubular ends being respectively formed with opposite wings or ears
and gaps or slots, which are engaged with each other on the tubular ends being
telescoped, thus forming a lock or connection.
The base of the lower conoidal segment is extended into a circular plate, gripped
by a radiating armed bracket, whose middle part is fitted with an ordinary Brays
or other loose gas nipple or burner, which may be wormed at both top and bottom,
whilst the end parts of the arms are extended upwards and have shoulders for a
gallery to rest upon and also form clips for the securing of the chimney, whose
bottom edge rests upon projections of the said arms, and by having the said
arms so formed, air enters the chimney from the side.
The contracted end of the upper conical section is crossed by a bar disposed
edgewise and made from the same metal as the attachment wings. This bar
carries, on its uppermost edge, a fixed socket, into which the lower end of a loose
mantle prop, takes, after passing through the eyeletted middle of a wire-gauze
crown fitted in the enlarged mouth end of the funnel shaped upper section of the
body, the wire gauze of which is secured in position by forming a rest shoulder
near its open top the edge of which is turned over the edge of the gauze. Or
the edges of the central hole in the gauze may be only turned over and clenched,
or a tube may be run from the middle piercing to form the socket.
Resting upon the middle of the wire gauze and threaded upon the mantle prop,
is a slightly dome shaped deflector disc, spreader or baffle, for producing a hollow
flame in order that the same shall play equally upon the whole of the sides of
the mantle.
The whole of the parts are made from sheet metal, preferably by stamping and
raising processes.

By choking or contracting the body part of mixing chamber into
waist, a greater amount of atmospheric air is included with the gas, and the
gaseous mixture is concentrated in passing the choke, and then when freed into
the enlarged upper part of the chamber it gradually expands up to the point of
ignition beyond the wire gauze.

tale, or with a piece of wire gauze to prevent the burner being lit from the
bottom.

Improvements in, and in the Manufacture of, Burners for
Incandescent Gas Lighting.
I, JOHN WILSON, of 16, George Road, Edgbaston, in the City of Birmingham,
Dispensing Chemist, 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:―
This invention relates to atmospheric burners for incandescent lamps, and con-
sists in one part in a new construction of burner, and in another part in an
economical method of manufacturing the same.
The construction of the burner will be seen from the following detailed descrip-
tion in which reference is made to the accompanying drawings, in which
Figure 1 is a longitudinal section of a Bunsen burner modified in accordance
with my invention.
Figure 2 is a drawing of the gallery used to support all the other parts.
Figure 3 is a section and plan of the lower cone or mixing chamber.
Figures 4 and
represent an elevation of the rod-holder.
Like letters of reference indicate like parts throughout the drawings.
The burner (Figure 1) consists of a double-coned body part (A A) with the
narrow ends (B) of the cones coming together and forming a choke or waist (C)
alike unto the waist of an ordinary spool or reel, and each body part is made up
of attachable sections with the choked tubular ends being respectively formed
by filing the tubes vertically with opposite wings or ears (D) Fig. 3 and gaps
or slots (E) Fig. 3 through which slots the wings (R R) of the rod-holder Figs. 4
& 5 pass, and are bent round the tubular ends on being telescoped, thus forming
a lock or connection.
The base of the lower conoidal segment is extended into a circular plate (F,
Figs. 1 & 3) gripped by a radiating armed bracket (G) whose middle part is
fitted with an ordinary Bray's or other loose gas nipple or burner (H) which may
be wormed at both top and bottom, whilst the end parts of the arms are extended
upwards and have shoulders (J) for a gallery to rest upon and also form clips
for the securing of the chimney, whose bottom edge rests upon the said arms.
The contracted ends of the conical sections are crossed by a bar (K) disposed
edgewise, and made from the same metal as the attachment wings. This bar
carries, on its uppermost edge, a fixed socket (L) into which the lower end of
a loose mantle-prop (M) takes, after passing through the middle of a wire gauze
crown (N) fitted in the enlarged mouth end of the funnel-shaped upper section of
the body, the wire gauze of which is secured in position by forming a rest shoulder
near its open top the edge of which is turned over the edge of the gauze.
Threaded at the base of the mantle prop is a deflector disc, spreader, or baffle (0)
.

page_text: for producing a hollow flame, in order that, when the gas pressure is low, the
flame shall play equally upon the whole of the sides of the mantle.
The whole of the parts are made from sheet metal, preferably by spinning,
stamping and raising processes.
The open bottom of the mixing chamber may also be partly fitted with wire
gauze to prevent the burner being lit from the bottom.
Referring now particularly to Figure 3. The edges of the circular plate (F)
of the lower conoidal section may be turned under the radiating arm bracket
in the manner shown at (T) thus preventing the gas being lit inside this section,
and the piece of wire gauze mentioned above may be placed either above or below
the radiating arms. The turned over edges must not be too close to the gallery
or this will prevent the free passage of air into the lower section which is absolutely
necessary. The space left should measure about one sixteenth of an inch.
The angle of divergence of the sides of the two cones is about 60°. This angle
may be varied but must not be less than 11°.
The rod-holder or bar (Figs. 4 and 5) is disposed crosswise in order that it
may not resist the free passage of the mixed gas and air through the choke or
waist. It is stamped out of a flat piece of metal in the shape indicated by Fig. 5,
the top part being subsequently bent over to form a tube (L) which is brought
into the centre by slightly bending it at (Q). The wings (R) may be bent round
the tube (B Fig. 1) to more firmly keep it in position.
The sides of the aperture (S) Fig. 2) are threaded to take the loose nipple or
burner.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
"
1. In the manufacture of an atmospheric burner for the purpose of incandescent
gas lighting, the use of a burner of the pattern known as Bray's regulator
burner," for the purpose of governing the amount of gas passed into a conical
mixing chamber, substantially in the manner described.
2. The combination of two or more of the parts above described, and illustrated
by Figures 2, 3 and 4 in the accompanying drawings.
3. In an atmospheric burner for the purpose of incandescent lighting, the
extension of the lower conoidal section or mixing chamber into a plate.
4. For the purpose of supporting the mantle-prop, the manufacture and use of a
rod-holder consisting of a bar disposed edgewise, crossing, and supported by
falling into slots in, the tube of an atmospheric burner, substantially as described,
and illustrated by the accompanying drawings.
