Improvements in or in connection with Self-generating Vapor
Burners or Apparatus for Vaporising Liquid Hydro-carbons for
Heating, Lighting, or other Purposes.
I, EDWARD THOMAS OWEN of 25 Alpha Road, Millwall, London, E., Engineer,
do hereby declare the nature of this invention to be as follows:-
My present invention relates to improvements in or in connection with what are
commonly known as vapor burners or apparatus which in burning vaporise liquid
hydro-carbons for heating lighting or other purposes and such improvements may
be used in conjunction with self-generating vapor burners or apparatus such as
shown and described in my Patent No. 7023 of 1893 or same may be used
(separately or combined) with any other "vapor burners or similar apparatus to
which same may be applicable either wholly or in part.
"
According to one part of my present invention such lamps or vapor burners are
constructed and mounted in such a manner that the great fall hitherto necessary to
give the required amount of pressure to the liquid hydro-carbon can be considerably
reduced and a very steady flow of oil and consequently steady and intense flame
can be obtained either for heating or lighting-without the necessity of any packing
in the supply pipe as heretofore usual in some
vapor burners."
66
Furthermore the general arrangement and construction is carried out in such a
manner that accessibility to the different parts thereof and convenience in use are
greatly increased.
Also to other features and details of improvement all of which will be fully
described hereinafter.
The main (oil) reservoir may be of any convenient size and shape and may
advantageously be constructed with a set-back or recess or other suitable chamber
for the purpose of holding necessary tools etc. and also if desired a strainer may be
arranged in the filling plug to prevent dirt or solid matter getting in.
In a convenient part of the pipe leading from the reservoir to the regulating
cock or valve a suitable filter or straining appliance or vessel is arranged-so
constructed as to afford easy access to the interior thereof and may be arranged
to receive any suitable filtering or straining medium therein such as cotton, gauze,
asbestos, or otherwise.
The next part of my present invention which I will now describe relates to the
means for reducing fluctuations in the oil supply and requiring less fall for the
oil and for this purpose an oil and air reservoir or chamber is arranged (or same
may be arranged as two or more separate chambers having suitable regulating
means attached thereto if desired) in connection with any convenient part of the
oil supply pipe between the vaporising retort (or part where the oil is converted
into vapor) and the main (oil) reservoir and such chamber (or chambers) is advan-
tageously arranged in an inverted form over the said oil supply pipe.
The introduction of this chamber allows the back pressure in the supply pipe
to sufficiently expand or escape into said chamber to produce a tendency to
equalise such back pressure and thus a kind of equilibrium is set up and a steady
flow of oil ensured.
An alternative arrangement to the above is with a looped pipe connection
(or equivalent return passage) and valve or valves so arranged as to equalise

page_text: the pressure in pipes or passages to burner and prevent the oil from being
forced away from the vaporising chamber or retort by the pressure generated
therein.
If desired-back pressure valves may be mounted in connection with this
equilibrium arrangement so that in this manner the oil will be found to flow
steadily down the supply pipe to the vaporising part thereof or vaporising retort
no matter what the pressure may be, and thus a steady oil supply is obtained and
consequently a steady flame.
The cone or cover (surrounding the burner nipple) such as set forth in my said
Patent No. 7023 of 1893 may be arranged on an improved plan viz.: such cone is
carried up and terminates in a hood or top part which may be wider than the cone
itself and which top part or hood is formed of perforated metal or other suitable
reticulated material so that the flame burns through same somewhat after the
manner of a Bunsen gauze burner.
Also this cone or cover may be arranged either with or without air regulating
devices therein or thereon.
•
A cup may be formed round the burner vipple either cast thereon or otherwise
suitably formed or mounted in a position to hold a small supply of oil or spirit for
preliminary heating of the apparatus to start same-and air holes or passages may
be arranged to pass through this oil cup or holder to assist combustion and also
I may arrange a cone or hood thereover and a suitable wick or equivalent therein
so that same will act somewhat after the manner of the well-known oil lamp burners
to produce more complete combustion and prevent smoke and smell in starting th
apparatus.
To prevent the small portion of oil left in the pipes etc. (after the regulating
valve or cock is shut off when it is desired to put the lamp out) from blowing out
of the nipple and causing smoke or disagreeable smell a suitable cap or cover may
be arranged either on a hinge or separately (for instance on the end of a spanner
or pricker) for the purpose of covering the burner nipple and as same is made to
fit this nipple closely thus prevents any escape of vapor after the lamp is
turned out.
The above improvements may be used separately or jointly in connection with
any suitable vapor burners and whether same be supplied with oil by pressure or
not as desired.

Improvements in or in connection
with Self-generating Vapor
Burners or Apparatus for Vaporising Liquid Hydro-carbons for
Heating, Lighting, or other Purposes.
1, EDWARD THOMAS OWEN of 25, Alpha Road, Millwall, London, E. 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 :-
My present invention relates to improvements in or in connection with what are
commonly known as vapor burners or apparatus which in burning vaporise liquid
hydro-carbons for heating lighting or other purposes and such improvements may
be used in conjunction with self-generating vapor burners or apparatus such as

any
or similar apparatus to which same

may be applicable either wholly or in part.
vapor
According to one part of my present invention such lamps or vapor burners are
constructed and mounted in such a manner that the fall hitherto necessary to give
the required amount of pressure to the liquid hydro-carbon can be considerably
reduced and a very steady flow of oil and consequently steady and intense flame
can be obtained either for heating or lighting-without depending on the
packing in the supply pipe as has hitherto usually been required in most "vapor
burners."
Furthermore the general arrangement and construction is carried out in such a
manner that accessibility to the different parts thereof and convenience in use are
greatly increased. Also to other features and details of improvement all of which
will be fully described hereinafter.
And in order that my present invention may be easily understood and readily
carried into practice I will now proceed to fully describe same with reference to
the drawings hereunto annexed.
The main (oil) reservoir A may be of any convenient size and shape and may
advantageously be constructed with a set-back or recess or other suitable chamber
such as B for the purpose of holding necessary tools etc. and also if desired a
strainer may or may not be arranged in the filling orifice C to prevent dirt or
solid matter getting into the reservoir A.
In a convenient part of the pipe D leading from the reservoir A to the regulating
cock or valve E a suitable filter or straining appliance or vessel (not shown) is or
may be arranged-so constructed as to afford easy access to the interior thereof
and may be arranged to receive any suitable filtering or straining medium therein
such as cotton gauze asbestos or otherwise.
I will now describe the means for reducing fluctuations in the oil supply and
requiring less fall for the oil-and for this purpose an oil and air reservoir or
chamber F is arranged (or same may be arranged as two or more separate chambers
not shown such as a row or succession of similar chambers to F arranged either
side by side or vertically over each other such chamber or chambers having
suitable regulating means attached thereto if desired (such as a cock or valve so
that any one chamber F or set of chambers may be shut off as desired to control
the flame) in connection with any convenient part of the oil supply pipe D
between the vaporising retort G (or part where the oil is converted into vapor)
and the main (oil) reservoir A and such chamber F (or chambers) is advan-
tageously though not necessarily formed of or about the shape as shown in the
drawings and is mounted in an inverted form over the said oil supply pipe D.
The introduction of this chamber F allows the back pressure in the supply pipe D
to sufficiently expand or escape into said chamber to produce a tendency to equalise
such back pressure and thus a kind of equilibrium is set up and a steady flow of
oil ensured.
An alternative arrangement to the above is with a looped pipe connection (or
equivalent return passage) and valve or valves so arranged (for instance as shown
in dotted lines Z in the drawings) as to equalise the pressure in the pipes or passages
to burner and prevent the oil from being forced away from the vaporising chamber
or retort G by the pressure generated therein.
If desired a back pressure valve or valves Z' may be mounted in connection with
this equilibrium arrangement so that in this manner the oil will be found to flow
steadily down the supply pipe D to the vaporising part thereof or vaporizing
retort G no matter what the pressure may be and thus a steady oil supply is
obtained and consequently a steady flame.
The cone or cover H (surrounding the burner nipple I) such as set forth in my
said Patent No. 7023 of 1893 may be arranged on an improved plan viz. such cone
is carried up and terminates in a hood or top part H' which may be wider than the
cone itself H and which top part or hood H¹ is formed of perforated metal or other

page_text: suitable reticulated material so that the flame burns through same somewhat after
the manner of a Bunsen gauze burner.
The cone H may advantageously be formed with a pocket or swelling H' so that
the pipe D' leading from the retort G to the nipple I may be entirely enclosed
within said cone H and thereby kept heated.
Also a door or opening H* (either with or without a cover thereto as desired)
may be formed in the cone H to afford ready access to the nipple I.
Also this cone or cover H may be arranged either with or without air regulating
devices (not shown) therein or thereon across the bottom or elsewhere.
A cup may be formed round the burner nipple I or near same for instance the
cup K which may be either cast or otherwise suitably formed or mounted as
shown or in any other suitable position to hold a small supply of oil or spirit for
preliminary heating of the apparatus to start same and one or more air-holes or
air pipes Lor air holes or passages may be arranged to pass through this oil cup
or holder K to assist combustion and also 1 may arrange a cone or hood thereover
(not shown) and a suitable wick or packing of asbestos or equivalent M therein
so that same will act somewhat after the manner of the well-known oil lamp
burners to produce more complete combustion and prevent smoke and smell in
starting the apparatus.
To further assist in starting the apparatus-I may use any suitable device for
forcing air under pressure through the said air supply pipe L for instance a blow
pipe or a flexible ball N and connection (after the manner of the well-known scent
spray-producers) so that a strong jet (or jets) of air is forced out just above the
top of the asbestos or other material M in the cup K to thus rapidly heat up and
start the lamp.
To prevent the small portion of oil left in the pipes etc. (after the regulating valve
or cock E is shut off when it is desired to put the lamp out) from blowing out of
the nipple and causing smoke or disagreeable smell a suitable cap or cover (not
shown) may be arranged either on a hinge or separately (for instance on the end
of a spanner or pricker) for the purpose of covering the burner nipple and as same
is made to fit this nipple I closely thus prevents any escape of vapor after the lamp
is turned out..
Or a suitable drain cock (not shown) may be arranged in the pipe D leading to
the retort G to drain any oil left in said pipe.
The above improvements may be used separately or jointly in connection with
any suitable vapor burners to which same is applicable either in part or as a whole
and whether same be supplied with oil by pressure or not as desired.
O is a set screw which is screwed through the part K₁ of the casting a recess
being formed between said part K₁ and the cup K adapted to receive therein
the screw cap or plug or other device closing or forming the end D* of the supply
pipe D D so that the latter is thus firmly held in position by the said fastening
screw and can be easily released and removed for cleaning repairs etc.
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. In self-generating vapor burners-the use and application of an air chamber
in or on or otherwise in connection with the oil supply pipe at a point between the
vaporising chamber or retort and the oil reservoir said air chamber being combined
and arranged to act in such a manner that back pressure or a part of the back
pressure from the said retort will pass into said air chamber and compress the air
or vapor therein the latter having no means of escape while upon reduction of said
pressure in the retort the compressed air or vapor in said air chamber will expand
thus maintaining a steady or approximately steady pressure or flow of vapor from
the retort to the burner nipple.
2. In self-generating vapor burners-the use and application of an air chamber
in or on or otherwise in connection with the oil supply pipe at a point between the

page_text: vaporising chamber or retort and the oil reservoir arranged to act substantially in
the manner and for the purposes herein before described.
3. In self-generating vapor burners-the use and application of a chamber such
as F mounted in connection with the oil supply pipe between the vaporising chamber
or retort and the reservoir combined and arranged to act substantially in the manner
and for the purposes hereinbefore set forth.
4. In self-generating vapor burners-the use and application with same of a loop
or return pipe connected from one part of the oil supply pipe adjacent to the retort
or vaporising chamber to another part of said supply pipe more distant from said
retort or vaporising chamber substantially in the manner and for the purposes
herein before described.
5. In self-generating vapor burners the combination with a cone or enclosure
wall such as H of a perforated hood or top thereto such as H' arranged and acting
substantially in the manner and for the purposes hereinbefore set forth.
'
6. The improved means for the heating at starting of self-generating vapor
burners arranged combined and acting substantially in the manner and for the
purposes hereinbefore set forth.
7. The construction of self-generating vapor burners arranged to act substantially
in the manner and for the purposes hereinbefore described and illustrated in the
drawings hereunto annexed.
