PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Incandescent Gas
Burners.
I, JOHN WILSON, of 16, George Road, Edgbaston, Birmingham, Dispensing
Chemist, do hereby declare the nature of this invention to be as follows:-
This invention relates to atmospheric burners for incandescent gas lamps, and
consists in one part of an alteration in the construction of the invention described
in Specification No. 24328 dated October 21st 1897, and in another part of a new
form of nipple burner and mixing chamber; and has for one of its objects to
construct an efficient atmospheric burner, and for another object to simplify and
reduce the cost of manufacture of burners for incandescent gas lighting.
The improved burner which is of the Bunsen or atmospheric type consists of
the tube part of an ordinary burner sumounted by a funnel-shaped crown, through
the enlarged end of which, suitably fitted with gauze or perforated metal, passes
the tube part of a rod-holder, to hold the rod, which in its turn supports the
mantle to be rendered incandescent.
Thus I take the open-topped shank of an ordinary gas-burner, but instead
of taking out the bottom, pierce one or more very small holes in the base for the
admission of gas. I leave the tapered and threaded end whole for a sufficient
distance for it to effectually close the nozzle of an ordinary gas bracket when
screwed into it. This would generally be for about ths of an inch; and
immediately above this space I perforate the shank for the admission of air. The
open top of the shank is slotted to receive the bar disposed crosswise as described
in Specification No. 24328/97.
Either over or into the tube thus prepared I place the tubular end, also slotted,
of the funnel-shaped crown forming the upper section, having previously fixed
the rod-holder in position by allowing the lateral ends of the bar to drop into
the slots in either tube, and with the bent-over portion (forming a tube) pro-
truding through the gauze or perforated metal cap which crowns or closes the
top section.
I place the rod, cleft at its upper end to receive the mantle, in this tube, having
previously threaded upon the tube a disc, intended to produce a hollow flame,
and to prevent hissing of the gas.
Upon the tapered and threaded end of the shank, and above the apertures for
the admission of air I screw a sheet of metal to prevent the gas being lit inside
the shank. In order to serve a useful purpose this sheet of metal may be a
gallery to support a globe, and if desired, a chimney.
The whole of the parts are made from sheet metal preferably by spinning or
stamping and raising processes, the shank being a "drawn through" blank made
in the usual way.
The sides of the shank may also be fitted with wire gauze if desired.
It is obvious that the body part of this burner may be produced in one piece
instead of two by making a cone threaded at its point, perforated as described,
capped at its widest end and sloted in the sides.

Burners.
I, JOHN WILSON, of 16, George Road, Edgbaston, 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 gas lamps, and
consists in one part of an alteration in the construction of the invention described
in Specification No. 24328 dated October 21st 1897, and in another part of a new
form of nipple burner and mixing chamber; and has for one of its objects to
construct an efficient atmospheric burner, and for another object to simplify and
reduce the cost of manufacture of burners for incandescent gas lighting
The improved burner, which is of the Bunsen or atmospheric type, consists of
the tube part of an ordinary burner altered as described, surmounted by a cap
or crown, through the top of which, suitably perforated, or fitted with gauze,
passes the tube part of a rod-holder, to hold the rod which in its turn supports
the mantle to be rendered incandescent.
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 the new form of nipple burner or mixing
chamber.
Figure 2 is an elevation of the rod-holder.
Figure 3 represents section of the different forms of caps or crowns, any of
which may be used to form the upper section.
Figure 4 is a longitudinal section of the whole burner.
Like letters of reference denote like parts in all the drawings.
I take the open topped shank of an ordinary gas burner (Fig. 1) known in
commerce as a drawn-through blank" consisting of a tube closed at one end,
but instead of taking out the bottom piece one or more small holes (A) in the
base for the admission of a sufficient quantity of gas. I leave the tapered and
threaded end (B) whole, for a sufficient distance for it to effectually close the
nozzle of an ordinary gas bracket when screwed into it. This would generally be
for about three sixteenths of an inch, and immediately above this space I per-
forate the shank for the admission of air (C). The open top of the shank is
slotted (D) to receive the bar disposed crosswise (Fig. 2) as described in Specifica-
tion No. 24328/97.
Either over, or into the tube thus prepared I place the tubular end (E) also
slotted. of the cap or crown forming the upper section (Fig. 3) having previously
fixed the rod-holder (Fig. 2) in position by allowing the lateral ends (F) of the
bar to drop into the slots in either tube, and with the bent-over portion (G) form-
ing a tube, protruding through the gauze (N) or perforated metal cap which
closes the top section.
I place the rod (H) cleft at its upper end to receive the mantle, into this tube,
having previously threaded upon the tube a disc (J) intended to produce a hollow
flame and to prevent hissing of the gas.
Upon the tapered end of the shank and above the apertures for the admission
of air I screw a sheet of metal to prevent the gas being lit inside the shank. In
order to serve a useful purpose this sheet of metal may be a gallery to support a
globe (L) and if desired. a chimney (M).
The whole of the parts are made from sheet metal, preferably by spinning or

page_text: stamping and raising processes, the shank being a drawn-through blank maqe
in the usual way.
Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what I
claim is:-
(1) The manufacture and use of a burner for incandescent gas lighting con-
sisting of the altered shank of a gas burner such as is in general use converted
into an atmospheric burner by leaving it closed at the bottom except for a very
small hole or holes for the admission of gas, with an aperture or apertures for
the admission of air near to its base, and either with or without slots filed or
pierced at the top substantially as described.
(2) The combination in one burner for the purpose of incandescent gas lighting
of the shank altered as described, with the rod-holder described in Specification
No. 24328/97 and illustrated in Fig. 2 in the accompanying drawings.
(3) The combination in one burner for the purpose of incandescent gas light-
ing of the shank altered as described with either of the caps or crowns described
above, and illustrated by Fig. 3 in the accompanying drawings.
Doted this Fifth day of September 1899.
