PROVISIONAL SPECIFICATION.
Improvements in Heating and Illuminating Lamps.
I, EUGENE GEORGE CAMELINAT of 65 Albion Street, in the City of
Birmingham, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in or additions to the wick parts of
heating and illuminating lamps, and particularly to lamps for the heating of boiling
vessels where spirit or highly volatile hydrocarbon oils are employed as the heating
agent, and also to illuminating lamps for domestic use where ordinary hydrocarbon
oils are employed.
My invention has for its object principally the prevention of explosions by the
wick descending into the oil reservoir.
According to my improvements, the wick, which is preferably circular, is pro-
vided with an internal support in the form of a loosely fitted metal tube, over
which the wick is slipped, so that the wick and tube move together when the
former is raised or lowered.
In carrying out my improvements in connection with a spirit lamp, I take an
ordinary shell body part fitted with a shell burner socketting in the open mouth of
the reservoir or spirit container.
The burner has an axial hole through its middle of the diameter of the wick,
within which a loosely fitted tube, in length about equal to the distance between
the top of the burner and the bottom of the container, is located.
The burner may have a winder with teeth engaging with the wick connected.
with the outside of the tube, so that as the winder is turned, the wick and tube
move together.
By turning the winder in one direction, the wick and its tube is raised for
lighting and by turning the winder in the reverse direction, the wick and tube are
lowered for extinguishing, with the bottom of the tube coming upon the bottom of
the container, thereby preventing the wick from being lowered too far, and thus
the tube forms a stop for limiting the lowering and thereby prevents the wick
from descending into the spirit, which oftentimes occurs and frequently explosions
ensue.
In flat wicks 1 prefer to employ. a flat tube or internal support.
The application of my invention to illuminating lamps differs in no essential
respect from its application to a heating lamp as herein described.
Dated this 3rd day of July 1895.

Improvements in Heating and Illuminating Lamps.
I, EUGENE GEORGE CAMELINAT of 65, Albion Street, in the City of
Birmingham, Manufacturer, 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 :—
This invention relates to improvements in or additions to the wick parts of
heating and illuminating lamps, and particularly to lamps for the heating of boiling
vessels where spirit or highly volatile hydrocarbon oils are employed as the heating
agent and also to illuminating lamps for domestic use where ordinary hydrocarbon
oils are employed.
My invention has for its object principally the prevention of explosions by the
wick slipping down or descending into the oil reservoir from the wick casing, which
oftentimes occurs where long wicks are employed, consequent upon the weight of
the lower part of the wick being sufficient to drag its upper end out of the casing.
According to my improvements, the wick, which is preferably circular, is
provided with an internal support in the form of a metal tube, over which the wick
is slipped, so that the wick and tube move together when the former is raised or
lowered, although if necessary the wick may be loosely fitted and slide upon the
internal support when raised or lowered, in which case the bottom end of the
supporting tube rests on the bottom of the spirit or oil reservoir.
In carrying out my improvements in connection with a spirit lamp, I take an
ordinary shell body part fitted with a shell burner socketting in the open mouth of
the reservoir or spirit container.
The burner has an axial wick casing through its middle, of the diameter of the
wick, within which a tube, in length a little greater than the distance between
the wick winder and the bottom of the container, is located.
The teeth of the winder engage with the wick connected with the outside of the
• tube, so that as the winder is turned, the wick and tube move together.
By turning the winder in one direction, the wick and its tube is raised for
lighting and by turning the winder in the reverse direction, the wick and tube are
lowered for extinguishing, with the bottom of the tube coming upon the bottom of
the container, thereby preventing the wick from being lowered too far, and thus
the tube forms a stop for limiting the lowering and thereby prevents the wick
from descending into the spirit, which oftentimes occurs and frequently explosions
ensue.
In flat wicks I prefer to employ a flat tube or internal support.
The application of my invention to illuminating lamps differs in no essential
respect from its application to a heating lamp as berein described.
Figure 1 of the accompanying drawing represents in vertical section, a spirit
heating-lamp provided with improvements in accordance with my invention.
Figure 2 is an elevation of the lamp.
Figure 3 is an elevation of the wick, which has the internal tube support
within it.
Figure 4 is a vertical section of Figure 3 upon the dotted line x.
Figure 5 is a vertical section of the wick separately.
Figure 6 is an elevation of the wick support separately.
Figure 7 is a cross section of Figure 4 upon the dotted lines .
Figure 8 is a cross section of Figure 5 upon the dotted lines a³.
Figure 9 is a cross section of Figure 6 upon the dotted lines ³.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
ai a spirit lamp, having a spirit reservoir a', and a removable burner a³,
fitted

page_text: with a wick casing a³, and a winder and winder axis a*, as, for raising and lowering
the wick b. Located within the middle of the wick, and running nearly from end
to end of the same, is an internal support or hollow tube c, preferably of a length
greater than the distance between the wick winder and the bottom, or equivalent
part of the reservoir, which said tube prevents the wick descending too far and
dropping into the spirit on the said wick being lowered for extinguishing, by
reason of its lower end c¹ coming against the bottom of the reservoir and so forming
a stop against the wick being lowered past the winder.
.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In heating and illuminating lamps, providing or locating within the wick, a fitted
or loose internal support or tube, preferably of a length greater than the distance
between the wick winder and the bottom of the reservoir or its equivalent, whereby
the tube is made to act as a stop for preventing the wick from being lowered or
allowed to descend below the winder, substantially as described and set forth.
