I HENRY KEEVIL of No. 1 Edward Street Bath, Soinersetshire, Gentleman do
hereby declare the nature of my invention for IMPROVEMENTS IN BURNERS OF OIL
LAMPS, AND THE MORE EFFECTUAL COMBUSTION OF THE OLL AND INCREASING THE
BRILLIANCY AND LIGHT OF THE FLAME OF PARAFFIN, PETROLEUM, AND BENZOLINE
LAMPS to be as follows, reference being had to the letters in the accompanying
drawings where similar letters refer to similar figures :-
as
Figure 1 represents a usual Petroleum oil burner-A is the metallic wick tube for
carrying the cotton wick B-C is a cap or nozzle to be placed over the wick tube
with an aperture to allow the wick to work and to be insulated from metallic contact
of the tube A by using a layer of any partial or complete non-conductor of heat such
cork-wood-tale-asbestos-leather woollen cloth-earthy matter or other non-
conducting material as shown at D by diagonal lines and thus partially prevents the
heat from the flame being directly communicated to the wick tube and prevents the
over heating of the oil-E is the usual metallic cone or dome used over the flame and
may be insulated in like manner by placing an insulating ring under its base as
shown at Fresting on a metallic rabbit as shown at G.

I HENRY KEEVIL of No. 1 Edward Street Bath Somersetshire Gentleman do
hereby declare the nature of my Invention for THE IMPROVEMENTS IN BURNERS FOR
HYDRO CARBON OIL LAMPS FOR THE MORE EFFECTUAL COMBUSTION OF THE OIL AND
INCREASING THE BRILLIANCY AND LIGHT AND HEAT OF THE FLAME OF PARAFFINE,
PETROLEUM AND BENZOLINE LAMPS and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement,
reference being had to the Letters in the accompanying Drawings with the
Provisional Specification where similar letters refer to similar figures
--
Figure 1 represents a usual Petroleum or Hydro Carbon Oil Lamp Burner
A is the metallic wick tube for carrying the cotton wick B-C is a cap or nozzle to
be placed over or round the mouth of the wick tube with an aperture to allow the
wick to work and to be insulated from metallic contact with the tube A by using a
layer or lining of any partial or complete non-conductor of heat such as-cork-wood
-tale asbestos-cloth-paper-earthy matter-plaster of paris-cement-ebonite-
vulcanite cellulose or other non conducting material as shown at D by diagonal
lines and thus partially prevents the heat from the flame being directly com-
municated to the wick tube or holder and to the cotton wick and oil or Lamp reservoir
and tending to prevent the over heating of the oil-E is the usual metallic cone or
dome used over the flame and may be insulated in like manner by placing an insulating
ring under its base as shown at F and made of the non conducting materials as above
described and shown resting on a metallic rabbit at G.
Figure 1 represents a front section.
Figure 2 represents a side section.
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 I do
not claim any special mechanical form or arrangement of the old and well known
parts of Hydro Carbon Oil Burners-but what I do claim as new in its application
to Hydro Carbon Oil Lamp Burners is simply
First the improvement and mode of partially preventing the excessive heat of
the flame being communicated to the wick tube or holder and wick materials and oil
by using a metallic or porcelaine china or stone ware cap or nozzle over or round the
mouth of the wick tube or holder, and insulated from metallic or immediate contact
with it by using either of those non conducting or other substances as hereinbefore
described, and thus by keeping down the temperature of the oil of the wick prevents
undue vaporisation and produces a more complete combustion in the flame and
greater heat for stove purposes.
Secondly I also claim the mode of insulating the base of the cone or dome from
perfect metallic contact with the gallery of the Burner substancially as indicated in
the Drawings The cone or dome may be made either with or without draft holes.
The cap or nozzle can be fitted and used on the wick tube or holder of any burner
at present in use and either with or without insulating the base of the dome. By
using the insulations as shown an hydro carbon oil of higher flashing temperature
may be moro safely used for Lamps for giving light or Lamps for stove purposes.
