page_text: HENRY DEFTY of number Two Casella Road, New Cross in the county of Kent,
Engineer, do hereby declare the nature of the said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The invention relates first to the combined arrangement with a Light Burner
whereby Gas Oils may be used for the purpose of illumination & the improvement
consists of a combined apparatus furnished with a Tank Reservoir and attachment to a
burner fitted with a Deflector which can be inserted into the centre of any Argand
Burner principle thereby diverting the current of the inner Tube and spreading the
Flame into a Globular shape, and by this method it tends to intensify the luminosity
and to reflect direct under the Burner doing away with all shadows such as are
occasioned and cast by the ordinary Lamp.
For ordinary oil Lamp or other purposes this invention is designed to effect the
efficiency of the light and to avoid any shadows in relation to its application to
Billiard Tables, Chandeliers or to any class of Lamp Burner.
The Stand or Chandelier Lamp consists of a Circular Coil of any dimension, round,
square or angular as taste may require and which forms the Tank or Oil Reservoir.
Immediately to this is attached branch pipes on which the Burner or Wick is fixed to
be lowered or raised, either by the worm or the Rack principle forming the Light for
the Disc. On this there is a Gallery or Stage on which the base glass stands and
iminediately on the top is a Disc, with a centre hole of the required dimensions and
on this again the top glass rests thus forming the chimney. Immediately on the
central air pipe is fixed a small Deflector or Button to spread the light into the required
shape. By this mode of combined arrangement the Glasses or Chimneys are pro-
tected from breakage and the scorching heat of the flame, thus rendering them of
greater durability. On the Rim or Oil Tank can be fixed an opal or other class of
shade for the purpose of reflecting the light. The most important feature of this
invention is the arrangement of fixing Gas or oil Burners to be supplied with oil from
the Ring Reservoir made in a circular or any other form and either for Chandeliers
or Brackets.

tend to produce shadows such as is the case in the use of ordinary oil Lamps.
