1, EDMUND FORD HULSE of 203 Padgate Road, Warrington in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the burner cones of oil lamps and stoves, and its object
is to so construct and arrange them that they may be readily detachable if desired,
for trimming the wick and other purposes, and so also that the light from that
part of the flame within the cone may be utilised to a greater extent than at
present.
In carrying out my invention, I construct the cone separately, with or without
appliances at or near its base by means of which it may be secured to the lamp or
stove fittings, by a bayonet joint or its equivalent, or it may be constructed to fit.
upon or be held by a bead, flange, prongs or the like. I may employ the ordinary
or any suitable form but at present I prefer to construct it with a cross section
similar to the like section of a frustum of a cone. When it is desired to make
the light from that part of the flame within the cone available, as in illuminating
lamps, I construct the cone of a suitable transparent or semitransparent material
such as mica, glass, porcelain and the like.

Improvements in Oil Lamps and Stoves.
1, EDMUND FORD HULSE, of 203 Padgate Road, Warrington, in the County
of Lancaster, Engineer, do bereby 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 :-
This invention relates to the burner cones of oil lamps and stoves, and its object
is te so construct and arrange them that they may be readily detachable, if
desired, for trimming the wick and for other purposes, and so also that the light
from that part of the flame within the cone may be utilised to a greater extent
than at present.
In carrying out my invention, I construct the cone separately, with or without
appliances at or near its base by means of which it may be secured to the lamp or
stove fittings. I may employ the ordinary or any suitable form of cone, such for
example as one having a cross section similar to the similar section of a frustum of
a cone. When it is desired to make that part of the flame within the cone
available for illumination, I may construct the cone wholly or partly of a suitable
transparent or semi-transparent material such as mica, glass, porcelain and the like.

page_text: I will more fully describe my said invention with reference to the accompanying
drawings in which:-
Figure is a representation, in elevation and partly in section, of a сопе
attached by means of a bayonet joint.
Figure 2 shews a similar elevation of a cone attached by clips or prongs.
Figure 3 represents a vertical section of a glass cone and
Figure 4, a similar section of a mica cone.
Figures 5 and 6 shew in plan and vertical section respectively, a composite cone
as applied to a duplex burner.
Although I have illustrated my improvements, and shall hereinafter describe
them as applied to lamps only, it will be obvious that they may be similarly applied
to oil stoves.
In each of the figures, Cindicates the separately constructed dome. As already
set forth, this cone may be attached to the lamp by means of or without special
appliances. In the latter case it will suffice to make the cone a moderately good
fit as indicated in Figures 3 to 6 inclusive, so that the cone is held by contact
alone. It is desirable however that the lower edge of the cone should fit upon a
flange such as F, or within a recess, to prevent the possibility of lateral
displacement.
As shewn by Figures 1 and 2, the cones are of the ordinary dome shape. In
Figure 1, it is shewn as attached by means of a bayonet joint B, and in Figure 2,
by the prongs or clips P.
The cone represented by Figure 3 is constructed of glass and is preferred to
have the forin shewn. For a single wick burner it is circular in plan with a slit
for the flame. For duplex burners it would have a plan similar to that shewn by
Figure 5. Figure 4 illustrates a modification of the transparent cone shewn by
Figure 3. It is constructed of mica m, riveted or otherwise secured to the two
rings r r.
The cone represented by Figures 5 and 6 is constructed of glass for a duplex
burner.
In this cone there may be a metallic bridge b, sprung into the opening so
as to cover the space vertically above the part between the two burners.
R is the lamp tount or reservoir: W, the wick: T, the wick tube: and the
burner casing.
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 what
I claim is
1. Separate detachable metallic burner cones for oil lamps and stoves,
constructed and arranged substantially as herein before described with reference
to the accompanying drawings.
2. Separate detachable transparent burner cones for oil lamps and stoves,
constructed and arranged substantially as hereinbefore described with reference
to the accompanying drawings.
3. Glass burner cones for oil lamps and stoves, constructed and arranged
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
