An Improvement in Burners for Oil Lamps.
I, OLIVER IMRAY of No. 28 Southampton Buildings in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
to be as follows:-
The edges of the flat wick employed in an oil lamp are apt to project above the
other parts of the wick, causing irregularity of the flame and often also causing
smoke which darkens the glass near them. This invention relates to means of
preventing this evil, and of ensuring that the flame shall not rise higher at its edges
than it does at its middle, so that if smoke should be produced at all, it will be
about the middle and consequently as far as possible from the glass. For this
purpose, the mouth of the wick tube is made with a lip projecting a little inwards
at each edge so that, when the wick is raised, the ascent of each edge of the
wick is checked, and thus the upper face of the wick is slightly higher in the
middle than at its edges. When the wick, instead of being flat, is bent to form
a segment of a cylinder, the same modification is applied to the wick tube for
the same purpose. The inwardly projecting lips may be formed by turning in the
metal of the wick tube, or by fixing on the wick tube narrow strips of metal so as.
to overlap its edges.

An Improvement in Burners for Oil Lamps.
I, OLIVER IMRAY, of No. 28 Southampton Buildings, in the County of
London, Chartered Patent Agent, 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 :-
The edges of the flat wick employed in an oil lamp are apt to project above the
other parts of the wick, causing irregularity of the flame and often also causing
smoke which darkens the glass near them.
This invention relates to means of preventing this evil, and of ensuring that the
flame shall not rise higher at its edges than it does at its middle, so that if smoke
should be produced at all, it will be about the middle and consequently as far as
possible from the glass. For this purpose, the mouth of the wick tube is made
with a lip projecting a little inwards at each edge so that, when the wick is raised,
the ascent of each edge of the wick is checked, and thus the upper face of the wick
is slightly higher in the middle than at its edges. When the wick, instead of being
flat, is bent to form a segment of a cylinder, the same modification is applied
to the wick tube for the same purpose. The inwardly projecting lips may be

narrow strips of metal so as to overlap its edges.
Fig. 1 of the accompanying drawings is a vertical section of the gallery and air
cone of a lamp and the wick tube constructed according to my invention. Fig. 2
is a similar section shewing a modified construction of the wick tube; Figs. 3 and 4
are plans of the wick tubes constructed as shewn in Figs. 1 and 2 respectively. In
these figures, B is the wick tube, C the air cone, and D the gallery. As shewn in
Figs. 1 and 3 the mouth of the wick tube is made with a lip b turned inwards at each
edge. As shewn in Figs. 2 and 4 these lips are formed by narrow strips of
metal b¹¹ fixed on the wick tube. When the wick is raised, by turning the
button A in the usual way, the edges of the wick are held back by the inwardly
projecting lips 6 or 6' and the middle of the wick is a little higher, the top of the
wick being somewhat curved as indicated by the dotted line. When the flame
tends to smoke, the smoky part is about the middle, not at the edges, of the wick,
and consequently the glass does not become smoked.
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 :-
A wick tube for an oil lamp made with inwardly projecting lips at its edges,
substantially as and for the purpose set forth.
