Improvements in Burners for Burning Acetylene Gas for Heating,
Cooking, Soldering, or other like Purposes.
I, FREDERICK NICHOLAS BLANC, of 62, New Bond Street, in the County of
London, Engineer do hereby declare the nature of this invention (which has been
communicated to me from abroad by Raoul Türr of 3 Rue Meissonier, Paris, in the
Republic of France, Engineer) and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement.:―
The object of the invention is to provide means whereby acetylene gas is utilized
in a very efficient and economical manner for the production of heat for heating air
for apartments, for cooking, for soldering irons, and for other heating purposes, such
for example as for heating baths and the like. A burner constructed in accordance
with this invention consists of a small tube, or jet, by which the requisite amount of
acetylene gas is admitted to the burner. This small tube, or jet, opens into a
surrounding chamber with an orifice, or orifices, in its sides for the admission of air,
the said orifice, or orifices, being situated, or extending, above the lovel of the outlet
end of the said small tube, or jet, and the said chamber constituting a space in which
the acetylene gas becoines intimately mixed with the amount of air necessary for its
proper combustion. Above this chamber, which may be termed the mixing chamber,
is a continuation of lesser cross-sectional area than the mixing chambor, the said
continuation being preferably constituted by a small tube which can be adjusted in
effective length by sliding it up, or down, in an orifice in the top of the mixing
chamber.
The mixture of acetylene gas and air is ignited at the upper end of this tubular
continuation. One burner, or any number of burners, thus constructed can be
employed in combination with cooking apparatus, baths, stoves, soldering-irons, or
other heating apparatus.
Figure 1 of the accompanying drawings represents in vertical section, and
Figure 2 in elevation, a burner constructed according to this invention, adapted to
be screwed upon a nipple on the end of a pipe leading from any source of supply of
acetylene gas. a is a screwed socket to screw upon the said nipple, the upper end
of the said socket being formed as a jet a², having in it a fine perforation a³, for the
admission of acetylene gas to the mixing chamber b, constituted by the tubular
picco 2 having in it orifices, situated above, or extending upwards beyond, the
top of the jet a'. The said tubular piece is internally screwed at its lower end to
screw upon a screw on the jet a² as shewn. The upper end of the said tubular
picce receives a tube c, of some considerable length slidden into the upper end of
the said mixing chamber and capable of having its effective length adjusted by moving
it up, or down, and it can be secured in position by any suitable means when
properly adjusted.
Figures 3 and 4 shew a modified form of the burner adapted to be secured in an
internal screw on the end of the supply pipe for acetylene gas, the socket a and
jet a of Figures 1 and 2 being replaced by an externally screwed piece a on the
lower end of the tubular piece constituting the mixing chamber & provided with
orifices and an adjustable continuation tube c as in the previous case.
The cross-
sectional area of the tube c is, in both cases, considerably less than the cross sectional
area of the mixing chamber b.
Figure 5 shews three such burners applied to a cooking stove, and Figure 6 shews

page_text: them applied to a heating stove, whilst Figure 7 shows the application to a soldering-
iron the handle of which is hollow and contains an arrangement of burner analogous to
those herein before described.
The jet a² is secured in the hollow handle, and above it is the mixing chamber b
constituted by the continuation of the handle and having air inlet orifices, situated
relatively to the top of the jet a² as in the other arrangements. The contracted
tubular passage piece at c² constitutes the equivalent of the contracted tubular
passage in the other figures. The upper end of the handle is provided with any
suitable form of grip, or holder, for holding the copper-bit d.. It is shewn as
consisting of two side pieces e with cross pieces e² for engaging with recesses in the
copper-bit and with a screw for pinching the said bit d in place. The gas and air
are ignited above the part c² and the parts above are preferably open so that the flame
can play directly upon the copper-bit. The flexible pipe for the supply of acetylene
gas is attached at f.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A burner constructed substantially as herein before described and illustrated in
the examples Figures 1, 2, 3 and 4 of the accompanying drawings.
2. The application of a burner, or burners, such as those claimed by the prece ling
claiming clause, to cooking, or air heating apparatus, or other heating apparatus;
substantially as hereinbefore described and illustrated by the examples shewn in the
accompanying drawings.
3. The application of a burner such as is claimed by the preceding first claiming
clause to a soldering-iron substantially as hereinbefore described and illustrated.
4. The arrangement and combination of parts constituting a soldering-iron substan-
tially as hereinbefore described and illustrated in Figure 7 of the accompanying
drawings.
