An Improvement in Atmospheric Burners for Combustible Vapours.
I, JOHN SOLOMON VIVIAN BICKFORD, of Tredouvra, Falmouth, in the County of
Cornwall, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to atmospheric burners for heating by the combustion
of vapour of petroleum or other oils.
A burner according to this invention is of the following description.
A horizontal tube closed at one end has along its side, preferably its upper side,
a row of holes or a narrow slit, and it is placed within a cylinder of coarse wire
gauze, this cylinder being of larger diameter than the tube and capable of being
adjusted more or less eccentrically in relation to the tube.
A jet of combustible vapour, such as that of petroleum, being directed into
the open end of the tube, draws air with it, and the mixture of air and vapour
issues from the tube by the holes or slits and finally passes with more air through
the wire gauze. On being kindled, the mixture burns with a flame giving great
heat but little light, and is suitable for heating purposes generally.
Dated this 20th day of April 1897.

An Improvement in Atmospheric Burners for Combustible Vapours.
I, JOHN SOLOMON VIVIAN BICKFORD, of Camborne, (late of Tredouvra, Falmouth),
in the County of Cornwall, Engineer, do hereby declare the nature of this inven-
tion 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 heating by the combustion
of vapour of petroleum or other oils.
I shall describe a burner according to my invention referring to the accom-
panying drawings which shew the burner provided with means of vaporising the
oil.
Fig. 1 is a side view, Fig. 2 is an end view and Fig. 3 is a plan partly sectional.
From a space in the upper part of a block A which is supplied with oil by a
pipe a leading from an elevated reservoir or from a vessel under pressure, projects
an inclined pipe B from the end of which descends a pipe C to a jet D directed

page_text: into the mouth of a pipe E which through a space in the lower part of the
block A communicates with two pipes F F having perforations on their upper
sides.
Above these three pipes is supported a curved sheet G of wire network or coarse
gauze, or it might be a grating with narrow bars and intervalos.
The burner operates as follows.
The pipe B being heated by a temporary fire under it, the oil supplied at a as
it flows along the pipe B becomes vaporised, and the vapour issuing by the jet D
takes with it some air; the mixture of air and vapour issues through the holes
in the pipes F and mixed with more air passes through the network or grating G
and being kindled produces a powerfully heating flame which maintains the pro-
duction of the oil vapour and is also available for heating a boiler or any vessel
or object placed above.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what. I
claim is:-
A burner for combustible vapour, constructed and operating substantially as
described and illustrated.
