PROVISIONAL SPECIFICATION.
Improvements in and relating to Oil Lamps and Stoves.
I, EDMUND FORD HULSE of 203 Padgate Lane, Warrington in the County of
Lancaster, Lamp Manufacturer and Metal Worker, do hereby declare the nature
of this invention to be as follows:-
This invention relates to oil lamps and stoves and its chief object is to provide
meaus for freely admitting air to the oil reservoir while preventing the escape or
discharge of the oil when the lamp is carried, shaken, or overturned. Means are
also provided for the insertion of wicks.
The air is admitted through a bent or doubled tube or its equivalent which is so
arranged within the oil reservoir that both its ends are normally above the level of
the oil. One end of the tube passes through the fount or reservoir wall and is in
communication with the external atmosphere. The other end of the tube opens
above the level of the oil within the fount. The bent part of the tube extends to
or nearly to the bottom of the fount so as to project above the level of the oil
should the lamp be inverted. The inner end of the tube may be contained within
or be protected by gauze or the like which may to some extent be shielded from
splashes of oil by a disc or plate.
The bent tube may conveniently be formed upon or attached to the cap covering
the opening through which the fount is filled.
For inserting the wick into a wick tube or carrier I employ a piece of wire or a
metal or other strip or the like which is thin enough to easily pass between the
wick and the side of the wick tube, and which is formed with fangs, points, or
projections upon its end. These points are of such a shape that they engage with
and move the wick when the strip or the like is moved in one direction but are
disengaged when it is moved in the other direction.

1. EDMUND FORD HULSE, of 203 Padgate Lane, Warrington, in the County
of Lancaster, Lamp Manufacturer and Metal Worker, 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 oil lamps and stoves and its chief object is to provide
means for freely admitting air to the oil reservoir while preventing the escape or

also provided for facilitating the insertion of wicks in wick tubes.

page_text: The air is admitted through a bent or doubled pipe or tube or its equivalent
which is so arranged within the oil reservoir that both its ends are, normally, above
the level of the oil. One end of the tube passes through the fount or reservoir
wall and is in communication with the external atmosphere. The other end of the
tube opens above the level of the oil within the fount. The bent part of the tube
extends to or nearly to the bottom of the fount so as to project above the level of
the oil should the lamp be inverted. The inner end of the tube may be contained
within or be protected by gauze or the like which may to some extent be shielded
from splashes of oil by a disc or plate.
The bent tube may conveniently be formed upon or attached to the cap covering
the opening through which the fount is filled.
For inserting the wick into the wick tube or carrier I employ a piece of wire or
a metal or other strip or the like which is thin enough to pass easily between the
wick and the side of the wick tube, and which is formed with fangs, points, or pro-
jections upon its end. These points are of such a shape that they engage with and
move the wick when the strip or the like is moved in one direction but are
disengaged when it is moved in the other direction.
In order that my invention may be more readily understood I have appended
hereto a sheet of drawings to which I will now refer.
Figure 1 illustrates partly in elevation and partly in section a wick casing and
burner to which the improved air admitting device is attached. This device
consists of a bent tube A the bent part of which extends nearly to the bottom.
of the fount B. One end of the tube, C, passes upwards through the burner
casing and communicates with the external air, while the other end D is contained
within the fount above the oil level. Air enters at the end C and is discharged
into the fount by the end D. The incoming cold air is thus prevented from
coming abruptly into contact with the heated vapour which may be in the upper
part of the fount. The end D may be returned or shielded in any suitable way to
prevent the ingress of oil.
Figure 2 illustrates, also partly in section and partly in elevation, the bent
tube attached to the cap which covers the oil inlet opening in the fount. In this
case the air inlet end C of the tube A passes through the cap E, and the inner
end D is protected from splashes by the curved or cupped plate F.
Figure 3 shows in section a modified form of air admitting device which is also
secured to the cap E. In this modification the bent part of the tube is replaced by
a short cylinder G into which both limbs A of the bent tube enter. Any splashes
of oil which do enter the tubes or tube A will collect in this cylinder and this
cylinder may be emptied or drained from time to time by removing the screwed or
other detachable end H. For similarly collecting splashes the bent part of the
tube may be suitably enlarged.
It will of course be understood that although I have only shown the bent tube
or its equivalent applied to the burner casing and to the oil inlet cap, it is equally
applicable to any part of the reservoir or fount.
Figures and 5 show two views at right angles to each other of one form of
wick inserter. It consists of a strip of metal J one end of which is pointed and
beut as shown at K. This end engages with the wick during insertion in the wick
tube or carrier and owing to its shape is kept in engagement during the forwari
A pull in the other direction, however, disengages the point and
withdraws the inserter.
Figure 6 is an illustration of an inserter with two points.
Wire or the like or strips of other suitable material may be substituted for the
metal strip J.
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 :-
1. An air admitting device for oil lamps or stoves, consisting of a bent tube or

page_text: its equivalent arranged substantially as hereinbefore described and as illustritel
by the accompanying drawings.
2. Air admitting devices for oil lamps or stoves, constructed and arranged
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
3. A wick inserter for oil lamps or stoves, consisting of a metal or other strip
or wire having one of its ends pointed and bent, substantially as and for the
purpose hereinbefore described and as illustrated by the accompanying drawings.
