PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Burning Self Generated Gas or
Vapourised Oil.
1, ALEXANDER REID MCLELLAN, of 15 Parkhouse Street, Camberwell, in
the County of Surrey, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to apparatus for burning self generated gas or vapourised
oil so constructed as to be easily cleaned and when required freed from accumulation
of pitch or other coking matter.
At the head of the apparatus the tubes conveying the hydro-carbon oil or other
combustible to be vapourised, are formed in a vertically zigzag shape round a
central conc or cylinder. The main supply tube leading from the reservoir is
bifurcated at the head of the apparatus the two forks or prongs being formed
vertically zigzag round the cylinder or cone in opposite directions and meeting at
the other end of the transverse diameter of the cylinder or cone. They are then
re-united and pass down the vapour jet or burner. The cylinder or cone is pro-
vided with removable top and bottom covers. The tubes through which the
combustible to be vapourised passes are open top and bottom and the ends of the
two contiguous or adjacent tubes are connected at the top or at the bottom by
branches or conduits in the top and bottom covers aforesaid. The removal of the
top and bottom covers therefore leaves the vapourising tubes open at both ends and
a cleaning tool may be easily passed therethrough when necessary.
The bottom cover carries a casting within which is the vapour jet or burner the
flame from which passes up through the centre of the cylinder or cone and projects
through and beyond the top of the cover. The oil and other liquid combustible in
the zigzag tubes surrounding the cylinder or cone is thus vapourised by the heat of
the flame. A draught door is provided on the casting for the admission of air in
large quantities when required for starting the lamp or for other purposes. The
vapourising tubes are surrounded with a cover or body having one 01' more
strengthening ribs as required.

Improvements in Apparatus for Burning Self Generated Gas or
Vapourised Oil.
I, ALEXANDER REID MCLELLAN, of 15 Parkhouse Street, Camberwell, in
the County of Surrey, Engineer, 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 apparatus for burning self-generated gas or vapourised
oil so constructed as to be easily cleaned and when required freed from accumulation
of pitch or other coking matter.
At the head of the apparatus the tubes conveying the hydro-carbon oil or other
combustible to be vapourised, are formed in vertically zigzag shape round a central
cone or cylinder. The main supply tube leading from the reservoir is bifurcated
at the head of the apparatus, the two forks or prongs being formed vertically

page_text: zigzag round the cylinder or cone in opposite directions and meeting at the other
end of the transverse diameter of the cylinder or cone. They are then re-united
and pass down the vapour jet or burner. The cylinder or cone is provided with
removable top and bottom covers. The tubes through which the combustible to be
vapourised passes are open top and bottom and the ends of the two contiguous or
adjacent tubes are connected at the top or at the bottom by branches or conduits
in the top and bottom covers aforesaid. The removal of the top and bottom covers
therefore leaves the vapourising tubes open at both ends and a cleaning tool may
be easily passed therethrough when necessary. The bottom cover carries a casting
within which is the vapour jet or burner the flame from which passes up through
the centre of the cylinder or cone and projects through and beyond the top of the
cover. The oil or other liquid combustible in the zigzag tubes surrounding the
cylinder or cone is thus vapourised by the heat of the flame. A draught door is
provided on the casting for the admission of air in large quantities when required
for starting the lamp or for other purposes. The vapourising tubes are surrounded
with a cover or body having one or more strengthening ribs as required.
The said head of the apparatus is connected to the supply pipe by means of an
asbestos packed swivel formed with a perforated hollow plug which serves to strain
the oil as it passes therethrough. The said swivel allows of the apparatus being
turned so as to give a vertical, horizontal, or inclined flame.
Before starting the light it is necessary to heat the head of the apparatus in
order that the oil may be vapourised in its passage therethrough to the jet or burner.
For this purpose I arrange a metallic cup so as to be adjustably secured upon the
oil supply pipe of the apparatus at any required distance below the head or
vapouriser. In the said cup I place some burning cotton waste saturated with oil,
the flame arising from which heats the head of the apparatus so that when the
supply of oil is turned on it is vapourised and burns at the jet.
And in order that my invention may be more fully understood and carried into
practice, I will now proceed to describe the same with reference to the accom-
panying sheet of drawings in which Figure 1 shews a vertical section and Figure 2
a plan (partly in section) of the apparatus herein described.
At the head a of the apparatus the tubes & conveying the hydro-carbon oil or
other combustible to be vapourised, are formed in a vertically zigzag shape round
a central cone or cylinder c. The main supply tube d leading from the reservoir is
bifurcated at e in the head of the apparatus, the two forks or prongs being formed
vertically zigzag round the cylinder or cone in opposite directions and meeting
at at the other end of the transverse diameter of the cylinder or cone. They
are then re-united and pass down the vapour jet or burner g. The cylinder or cone
is provided with removable top and bottom covers and j. The tubes through
which the combustible to be vapourised passes are open top and bottom and the
ends of the two contiguous or adjacent tubes are connected at the top or at the
bottom by branches or conduits which are closed by the top and bottom covers
aforesaid. The removal of the top and bottom covers h, j, therefore leaves the
vapourising tubes open at both ends and a cleaning tool may be easily passed
therethrough when necessary. The bottom cover carries a hood k within which is
the vapour jet or burner y the flame from which passes up through the centre of the
cylinder or cone c and projects through and beyond the top of the cover h. The
oil or other liquid combustible in the zigzag tubes & surrounding the cylinder or
cone is thus vapourised by the heat of the flame. A draught door / is provided
on the hood for the admission of air in large quantities when required for
regulating the flame or for other purposes. The vapourising tubes are surrounded
with a cover or body having one or more strengthening ribs m as required.
The head a of the apparatus is connected to the supply pipe n by means of the
swivel arrangement p packed with asbestos at r and formed with the perforated
hollow plug through which the oil is strained on its passage through the apparatus.
A. mut is provided to tighten up the swivel against its packing.
The cup u is adjustably secured upon the oil supply pipe n by means of a set

page_text: screw t so that the distance between it and the vapouriser a may be readily
regulated. When the burning cotton-waste is placed in the cup to heat the
vapouriser a the hood is disconnected and removed until the vapourised oil is
burning at the jet y.
Plugs are provided as shewn at all the angles of the jet 7 to allow of the
admission of a cleaning brush to all parts of the said jet.
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) The arrangement of the zigzag vapourising tubes around the central cone c,
and the means of closing the ends of the same by the detachable covers h, j,
substantially as herein described and illustrated in the accompanying drawings.
(2) The combination of the asbestos packed strainer-swivel P. with the
vapouriser a each constructed substantially as herein described and illustrated in
the accompanying drawings.
(3) Apparatus for burning self-generated gas or vapourised oil, constructed so as
to be easily cleaned and when required freed from accumulation of pitch or other
coking matter, substantially as herein described and illustrated in the
accompanying
drawings.
