:-
I JAMES OSBORN SPONG of 226 High Holborn, Middlesex, Domestic Appliances
Manufacturer, do hereby declare the nature of my said invention to be as follows:
This invention relates to apparatus attachable to or forming part of an ordinary
gas branch, bracket, gasalier or the like, said apparatus or appliance being charged
with paraffin or other heavy oil or it may be a light oil and with a tube containing
awick provided with a button for adjusting the wick and so regulating the height
and spread of the gas flame. The wick tube is preferably flat and of curved
formation so that its end approaches the flame a portion of the wick being within the
gas flame and burning therewith which not only increases the size of the gas flame
But enriches the light and produces greater purity, the edge of the flame being
particularly steady and regular.
The apparatus containing the oil is preferably close to the gas burner but it may be
at any desired distance therefrom and the wick be fed to the gas flame from any
required part.
I purpose making the gas burner or nipple socket in a piece with the vessel a threaded
projecting end at the bottom enabling it to be attached to an ordinary socket as
burners are attached now but the apparatus may be made for suspension from an
ordinary gas branch the wick tube being within range of the gas burner so that the
flame is composed of a mixture of ordinary coal gas and paraffin or its equivalent
oil.

Novel Means and Apparatus to Facilitate the Enrichment and Purity
of Flame of Coal Gas.
I, JAMES OSBORN SPONG of 226 High Holborn, Middlesex, Domestic Appliances
Manufacturer, 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 attachable to or forming part of an ordinary
gas branch, bracket, gasalier, or the like, said apparatus or appliance being charged
with paraffin or other heavy oils, or it may be a light oil with a tube containing a wick
provided with a button for adjusting the wick and so regulating the height and spread
of the gas flame. The wick tube is preferably flat and of curved formation, so that
its end approaches the flame, a portion of the wick being within the gas flame and
burning therewith, which not only increases the size of the gas flame but enriches
the light and produces greater purity, the edge of the flame being particularly steady
and regular.
The apparatus containing the oil is preferably close to the gas burner but it may be
at any desired distance therefrom and the wick be fed to the gas flame from any
required part.
purpose making the gas burner or nipple socket in a piece with the vessel, a
threaded projecting end at the bottom enabling it to be attached to an ordinary socket
as burners are attached now, but the apparatus may be made for suspension from an
ordinary gas branch, the wick tube being within range of the gas burner so that the
flame is composed of a mixture of ordinary coal or like gas and paraffin or its
equivalent oil.
The annexed drawings represent several examples in which I combine the two
flames before mentioned.
Figure 1 is a section of an oil vessel A having a gas supply pipe B as part of same
and passing up through the centre, the upper part having the usual nipple or burner Ü
and the lower part D screw threaded for its attachment to an ordinary gas branch or
pipe.
E is the oil wick tube rising from the upper part of the oil vessel and with its outer
end bent, so that its nozzle projects slightly over the gas nipple C to be within range
of the gas flame, so that the two, gas and oil, burn in contact.
Fis the turn button by which the wick G can be regulated and H is the hole by
which the oil vessel can be charged.
Figure 2 is a similar view, except that the oil vessel A has a tube I through it for
the gas supply pipe B, shown detached at Figure 3, to pass through it.
Figure 4 shows the nozzle E of the oil vessel with a clip J on its under side to pass
over the nipple C of the gas burner, the oil vessel A resting within a cup on the gas
supply pipe B to steady it in position, the oil supply vessel being separate and
attachable to a gas burner. The clip J may be provided with a screw arrangement
for fixing it in position, as represented at Figure 5.
According to Figure 6, the oil vessel A is suspended by the clip J from the gas
branch B.
Figure 7 shows the oil vessel A supported by the gas branch B which has ears or
lugs for pins L on the lower part of the vessel A to pass through, so that the

page_text: vessel A is supported in proper position, the pins L serving as feet to the vessel when
removed for refilling or for putting a fresh wick in.
Figure 8 shows a series of gas burners C supplied by a pipe B common to all, the
oil vessel A having wick tubes E, one for each gas burner.
Instead of having one gas flame to one oil wick, two gas supply pipes may be
furnished to a single oil wick, as at Figure 9, or two oil wicks may be fitted to one gas
supply, as at Figure 10.
All the Figures 1 to 9 show flat wicks to be used in combination with the gas
burners of the ordinary construction but at Figure 10 the gas jets issue from a burner
in line so as to make a series of small flames which lick themselves into contact and
constitute one large or broad flame which burns in combination with the flame of the
oil wicks.
Figures 11 and 12 show how I arrange my oil vessel A with an Argand gas
burner.
According to Figure 11. I use a circular wick outside the Argand burner and its
gas supply pipe B with an air space through the centre of the oil vessel to support
internal combustion of the flame, but at Figure 12 I show the Argand gas burner
outside of the oil wick tube, the wick being flat but brought into circular form from
the shape of the tube, air for supporting combustion of the interior of the flame being
free to enter at the aperture M.
Figure 13 is a view somewhat similar to Figure 1 but without the nipple C, so that
a large flame of gas issues from the outlet and burns in combination with the flanie
from a circular oil wick which is fed with oil from the vessel A.
Figures 14 and 15 show an arrangement of oil vessel A and gas branch B when a
porous stone wick is employed in the nozzle E.
For this purpose I provide the nozzle E with a tap N, so that the oil may flow
freely from the vessel A to the stone wick, the quantity being regulated by turning
the tap N more or less in the proper-direction.
The vessel A at Figure 14 is supported on the gas branch B in a similar manner
to that described with reference to Figure 7, the pins L being on the lower part of
the pedestal P it being essential where porous stone wicks are used that the oil vessel
be above the gas flame.
All the combinations shown from Figures 1 to 14 are for such as are used in
dwelling houses, shops, and other places but at Figure 15 I show the application of
my porous stone wick arrangement of nozzle E to an ordinary street lamp.
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:
1. The construction of oil vessels in which the nozzle E is of curved or other shape
for its end to project over or above or in proximity to an ordinary gas burner, so
that the two flames, viz., gas and oil, commingle and burn as one flame, all as herein
described.
2. As a means for enriching and purifying the flame of coal or like gas, the com-
bination, therewith of an oil flame, as described.
3. The method of connecting or attaching an oil vessel with or to a gas supply
pipe, whether the oil vessel be provided with an ordinary or a porous stone wick all
as above described with reference to the annexed drawings.
