Improvements in Hydro-carbon Vapour Lamps for Lighting and
Heating.
I, ROBERT HENDERSON, of 2, Bruce Street, Dumbarton, in the County of Dumbarton,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide an industrial lamp of simple and,
inexpensive construction for vaporising and burning hydrocarbons such as paraffin,
and adapted for lighting or for heating purposes.
The improved lamp is composed of a vaporiser made in the form of a shallow

carbon or its vapour is led through a tube at right angles to its lower face this tube

jet orifice directed upwards against the central part of the disc or saucer like vaporiser.
The tube for conducting the hydrocarbon vapour may be carried upwards within the
vaporiser above the level of the liquid hydrocarbon so that only the vapour will be

I, ROBERT HENDERSON, of 9, Mansefield Place, Rothesay, Buteshire, Engineer
formerly of 2, Bruce Street, Dumbarton, in the County of Dumbarton, 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 has for its object to provide an industrial lamp of simple and
inexpensive construction for vaporising and burning hydrocarbons such as paraffin,
and adapted for lighting or for heating purposes.
The invention is illustrated by the accompanying drawings, Figure 1 being a
vertical section of the improved lamp, and Figure 2 a plan of same with the top
cover removed.
'The improved lamp is composed of a vaporiser made in the form of a shallow flauged
disc or saucer A provided with a screwed on cap or cover B. Into this vessel A
hydrocarbon from an overhead tank or under pressure is forced through a pipe C on
one side of the vessel A as shewn or on top, the hydrocarbon being vaporised or
partially vaporised in its passage through the vessel A. From the saucer or vessel A
the hydrocarbon or its vapour is led through a tube D at right angles to the lower
face of the vessel, this tube D being extended downwards a short distance, bent
inwards at E and terminated in a small jet orifice F directed upwards against the
central part of the disc or saucer like vaporiser A. The tube D for conducting the
hydrocarbon vapour from the vessel A may be carried upwards within the vaporiser
above the level of the liquid hydrocarbon as shewn, so that only the vapour will be
conducted down to the burner at F. The jet portion of the tube may be further
supported by a dummy tube or limb G attached to the opposite side of the disc; and
at a short distance from the vaporiser a solid disc or washer H having in it a central
orifice or guideway is secured on these downward limbs D and G of the burner. A
shield I of cylindrical or other form is fitted over the burner F and tube D and
attached to the lower disc or washer H so as to leave only open the space between the
vaporising vessel A and the disc H below it. When the lamp is lit, which may be
effected in the usual way by burning oily waste under the vaporiser A, the jet of
hydrocarbon spray or vapour rises from the jet orifice F in the form of a flame
directed against the lower surface of the vaporiser and is thence deflected outwards
in annular forin between the vaporiser A and the disc H under it. Two or more
lamps on a piece or in the form of a cluster may be connected to a single oil supply
pipe.
The vaporising vessel A being made with a removable cap or cover B may be turned
out in a lathe so that its bottom part on which the flame plays may be reduced in
thickness to better expose the hydrocarbon to the heat of the flame issuing from
the burner, whilst providing also for readily cleaning out carbonised residue. The
vessel A may be further provided with a grid J as shewn which whilst being removable
to permit of the under side of the vessel being reduced in thickness as already
described, causes the hydrocarbon to travel in zig-zag form through the vessel A in the
direction shewn by the arrows, Figure 2, in order that it may be more completely
vaporised.

invention, and in what manner the same is to be performed, I declare that what I
claim is:-
The improved hydrocarbon vapour lamp for lighting and heating constructed and
operated substantially as described.
