Improvements in Atmospheric Burners for Oil Lamps or Stoves.
We, JOHN LIENRY WOODROFFE, Foreman, and JOHN WILLIAM BERNARD WRIGHT,
Manufacturer, both of 390, New John Street West, Birmingham, do hereby declare
the nature of our said invention to be as follows;
Our invention relates to that class of petroleum burners for stoves or lamps
patented by Jacques Aimé Vagner, in the year 1891, No. 21924.
In burners of this description we have discovered that there is a liability of the
flame to, flash back, that is, to change back from the non-luminous to the
luminous flame, such change taking place when the burner has become throroughly
heated, owing to the variation of the air currents; due to either placing upon or
removing from the top of the stove of a culinary utensil. The cause of such
lighting back is we believe the exposure of the non-burning side of the wick, and
the readiness with which it is effected by the flame burning on the other side.
Our invention consists in the provision of a plate or rim of metal or other sub-
stance, running the whole length of the wick-case on its upper non-burning side.
Such plate may be part of the wick-case, one side being higher than the other,
or it can be attached to or independent of same, its object being to exclude the
external air from the non-burning side of the wick until such wick reaches the
point where the atmospheric combustion takes place. The result of this is to
prevent any flame whatever, and at any time, being produced from this portion of
the wick, and to secure the flame being atmospheric in character from its very
beginning.

Improvements in Atmospheric Burners for Oil Lamps or Stoves.
We, JOHN HENRY WOODROFFE, Foreman, and JOHN WILLIAM BERNARD WRIGHT,
Manufacturer, both of 390, New John Street West, Birmingham, do hereby declare
the nature of our said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
Our invention relates to that class of petroleum burners for stoves or lamps for
which Letters Patent were granted to Jacques Aimé Vagner, No. 21924 of 1891.
With burners of this description there is a liability of the flame to flash back,
that is, to change back from a non-luminous to a luminous flame, such change
[Price 8d.]

page_text: taking place when the burner has become thoroughly heated, owing to the variation
of the air currents due to either placing upon or removing from the top of the
stove of a culinary utensil. We have discovered that the cause of such flashing or
lighting back is the exposure of the non-burning side of the wick, and the
readiness with which it is effected by the flame burning on the other side, and the
object of our present invention is to remedy this defect.
And in order that our said invention may be particularly described and ascer-
tained reference is hereby made to the accompanying drawing which illustrates
the application of our improvement, to an oil stove of the "cast base" type and
from which its application to other stoves and lamps will be readily understood.
Our invention consists in' providing a plate or rim a of metal or other 'substance,
running the whole length of the wick case b on its non-burning side. Such plate
may be part of the wick-case as shown in the drawing, one side being higher than
the other, or it may be attached to the wick-case or other suitable portion of the
burner, its object being to exclude the external air from the non-burning side of
the wick up to the point where the atmospheric combustion takes place.
By this 'means we effectually prevent any flame whatever, and at any time,
being produced from this portion of the 'wick, and ensure the flame being atmos-
pheric in character, immediately after ignition.

4: :
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is;
1. In an atmospheric burner for oil lamps and stoves, the application and use of
a plate or extension a of the wick-case 6, on the non-burning side of the wick,
substantially as and for the purpose specified.
2. The combination with the atmospheric burner illustrated by the drawing of a
plate or extension a of the wick case 6 on the non-burning side of the wick
substantially as and for the purpose described and shown by the drawing.
