Improvements in or appertaining to Hydrocarbon or Vapour Burners
for Lighting or Heating Purposes.
I, JOHN WATTS of 36 Glazebrook Street, Warrington in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object a device for burning hydrocarbons for lighting
or heating purposes. It is constructed with a vapouriser which is so heated by the
flame as to vapourise the liquid hydrocarbon passing through it. It is designed to
burn longer, be simpler to clean and cheaper to manufacture than other hydro-
carbon burners. There being no bell mouth required there is less noise, and
furthermore there is little or no spitting of oil as the burner is designed to cause any
oil which is not consumed to be caught by a dish.
In carrying my invention into effect, the retort or generator in which the liquid
is vapourised is, in my experimental apparatus, formed tubular in cross section, and
of rectangular shape in plan, but this shape is of course optional as any suitable
shape may be adopted. The liquid oil under compression enters through a pipe or
pipes from the store tank or accumulator, passes through the generator, where
during its passage through it, it is vapourised by the heat of the burner flame. The
vapour then passes through an exit pipe or pipes to a vapour jet, from whence it
issues to the burner. This burner is preferably formed by and between the walls of
the generator, and its shape is to some extent governed by the special shape of the
generator. It is provided with a conical plug with wings to keep it in the required
position and form a channel or orifice for the vapour and flame to pass through.
The vapour then after passing through the jet aforesaid impinges against this
conical plug and is distributed around it and ignited, the flame coming out through
the channel.
I prefer to employ a dish for catching any unconsumed oil that will not pass
through the burner, the conical plug preventing in great measure any spitting of
oil, which has been found to be a very dangerous feature hitherto in other burners.
Suitable holes with plugs are provided to facilitate the generator being cleaned at
intervals, the generator being preferably of rectangular shape in plan with a
cleaning hole at each corner. To light the burner, it must of course be heated
by an auxiliary flame such as by means of the oil in the dish or otherwise and thus
start the vapourisation of the oil.

1, JOHN WATTS of 36 Glazebrook Street, Warrington in the County of
Lancaster, Engineer, do hereby declare the nature of this invention and in what
mauner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention has for its object a device for burning hydrocarbons for lighting
or heating purposes. It is constructed with a vapouriser which is so heated by the
flame as to vapourise the liquid hydrocarbon passing through it. It is designed to
burn longer, be simpler to clean and cheaper to manufacture than other hydro-
carbou burners. There being no bell mouth required there is less noise, and
furthermore there is little or no spitting of oil as the burner may be designed to
cause any oil which is not consumed to be caught by a dish.
The invention will be understood from the following description, reference being
had to the accompanying drawings, in which,
Figure 1 is a front elevation of my improved burner and vapourising tubes
showing door in front closed;
Figure 2 a side elevation;
Figure 3 a longitudinal section through the burner showing door raised ;
Figure 4 a back elevation of the sheet metal cover.
In these, A are pipes, tubes or generators arranged round the flame in which the
oil supplied to the burner under pressure is converted into vapour. These tubes
may be cast in one piece or built up in separate pieces as preferred, and they may
be arranged in the form of a square so as to surround the flame as shown, or in any
other convenient form, the shape being of course entirely optional. The ends of
the tubes A are provided with holes having screwed plugs B which when removed
give access for cleaning out any deposit in the tubes. C is a pipe for feeding the
vapourising tubes A with oil from the store tank or accumulator, and a pipe
leading from the vapourising tubes A to the burner aperture E, there being
preferably a short length of screwed pipe d' which enables the pipe containing the
burner aperture to be disengaged for cleaning when required. F is a cylinder or
casing arranged concentric with burner aperture E, G a sheet metal cover by
which the back of the burner is protected from the wind, and G¹ perforations in
the sheet metal cover to supply air for supporting combustion. The pipe C when
mounted in a socket may be used for supporting the device in position, and it
enables the burner and vapourising tubes to be swivelled round so as to keep the
flame as it issues from the burner in the direction of the wind. This pipe C is
shown broken on the drawings so as to economise space. H is a door hinged to the
front of the burner. A dish for catching any unconsumed oil that has not been
vapourised or burnt may be employed.
The mode of action is as follows:-
The
The oil under pressure enters the vapourising tubes through the pipe C from the
tank or accumulator or other suitable source of supply. The flame from the ignited
gas or vapour issues from the burner aperture E, passes through the cylinder F and
between the tubes A and heats those tubes thus converting the combustible oil into
gas or vapour, which passes along pipe d to feed the burner aperture.
apparatus is thus self generating. To start the burner into operation all that is
necessary is to close down the door H and place some fibrous material saturated
with oil between the tubes A. or the cylinder F. This saturated material is ignited
and heats up the vapourising tubes A until a gas or vapour is generated from the oil
supplied thereto which will ignite at the burner aperture E. The door H is then
raised and the fibrous material removed. Or instead of using the fibrous material

page_text: aforesaid, the tubes A may be heated by an auxiliary flame, such as would
be produced by igniting the oil in the dish or otherwise, and so start the
vapourisation of the oil.
Originally I proposed to provide a conical plug with wings to keep it in the
required position and form a channel or orifice for the vapour and flame to pass
through. The vapour then after passing through the jet aforesaid impinged against
this conical plug and was distributed around it and ignited, the flame coming out
through the channel.
This arrangement however I have abandoned as I find it unnecessary for the
successful working of the burner.
Instead of providing the vapourising tubes with four plugs, as shown they may
be manufactured with two plugs at the top, also the burner aperture E may have
two holes in it and formed in a T shape with a plug at the back.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The improvement in hydrocarbon or vapour burners for producing light, and
heat, which consists in arranging the tubes or generators in which the oil or com-
bustible liquid is vapourised, to surround the flame in such a manner that the said
tubes are exposed to its full heat, whereby the tubes will be heated and the oil
supplied thereto converted into gas or vapour to feed the flame substantially as
described.
2. In hydrocarbon or vapour burners, the arrangement of the vapourising tubes
in a square or other suitable form so as to surround the flame, the ends of the
tubes being provided with holes having screwed plugs which when removed give
access for cleaning out any deposit in the tubes substantially as described.
3. In self generating gas or vapour burners, the combination therewith of
vapourising pipes or tubes arranged substantially as and for the purpose herein
described.
4. The combination and arrangement of gas or vapour burners having a burner
aperture E, vapourising tubes A, casing or cylinder F, and wind guard G,
substantially as described.
5. The use in combination with self generating gas or vapourising burners of a
door or shield H arranged at the front for use in starting the burner into operation
substantially as described.
6. The combination arrangement and construction of parts forming my improved
hydrocarbon or vapour burner substantially as set forth.
