COMPLETE SPECIFICATION.
Improvements in Lamps for Burning Benzoline or Inflammable Oils.
I, JOHN HENRY WALLIS of 56 Dingwall Road, Croydon, in the County of
Surrey, Professor of Music, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
This invention which relates to benzoline or other spirit lamps will be best
understood by referring to the accompanying drawing which represents my invention
as applied to a small benzoline or spirit lamp.
A is the lamp which may be of any desired construction and A' is the wick tube.
B is an inverted dome or cup made of glass or other suitable material which is
provided with a neck or tube B¹ adapted to fit on to the wick tube A¹ as shown.
C is the ordinary cap for fitting over the end of the wick tube A' to prevent
the evaporation of the spirit and C¹ is the chain by which the cap C is secured to
the wick regulating spindle D.
The chain in this example is longer than it is ordinarily so that it may extend
over the edge of the cup B when the cap C is applied to the wick tube A¹ while
the cup B is in position thereon.
Hitherto where glass chimneys or shields have been employed the air has been
allowed to enter by the bottom of the glass and thus in moving to blow the flame
about.
By the present invention the air can only enter by the top and the flame is thus
protected from currents of air which would cause it to flicker whilst being carried
about or otherwise.
The top being entirely open allows plenty of air to have access to the flame to
support combustion and further enables the lamps to be lighted without removing
the glass cup.
Owing to the steady atmosphere thus surrounding the flame a lamp which has
been designed to burn spirit may be used for burning mineral oils and more
particularly kerosene, a water white mineral oil, without smoking.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
The combination with a lamp for burning spirit or inflammable oil of a cup
such as B closed at its lower end having a neck or tube such as B' for fitting over

panying drawing.
