PROVISIONAL SPECIFICATION.
Improvements in Extinguishers for Paraffin or other Oil Lamps.
I JOHN WILLIAM UTTLEY of 219, Longmore Lane, Walton, in the county of
Lancaster, Railway Signal fitter, do hereby declare the nature of this invention to
be as follows :-
The invention has for its object a device for instantaneously extinguishing the
flame of an oil lamp. It is arranged in such a way that the flame is put out when
the wick is turned down before the oil in the reservoir can be ignited. It can
also be used as a self acting extinguisher for putting out the flame, when the
lamp is upset..
Many lamp accidents have been caused by moving down the wick in order to
extinguish the flame, such a distance that the oil becomes ignited or an explosion
occurs.
In carrying out the invention the wick tube is surrounded or partly surrounded
with an extinguisher casing or tube, fitting it preferably very loosely. The lower face
is chamfered so that it will not lie quite vertical and parallel with the wick tube. The
upper face is partly covered by a lip, so that when the extinguisher is resting in its
chamfered face, the said lip is over the wick and preferably covers the opening to the
wick tube.
When the wick is raised by the mechanism usually employed, it pushes aside the
extinguisher, or if preferred an eye or small handle may be provided for pulling it
aside, thus permitting the wick to be moved up.
When the wick is turned down for the purpose of extinguishing the flame, the
extinguisher casing or tube will, owing to its sloping or chamfered face fall back into
its normal position, and the lip will cover the wick or wick tube and thereby instantly
extinguish the flame, before the wick is moved down sufficiently to cause the flame to
ignite the oil.
If the lamp is upset the tube or casing slides over the wick and extinguishes the

Improvements in Extinguishers for Paraffin or other Oil Lamps.
I, JOHN WILLIAM UTTLEY of 219, Longmore Lane, Walton, in the County of
Lancaster, Railway Signal Fitter, 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 invention has for its object a device for instantaneously extinguishing the flame
of an oil lamp. It is arranged in such a way that the flame is put out when the wick
is turned down before the oil in the reservoir can be ignited. It can also be used as
a self-acting extinguisher for putting out the flame, when the lamp is upset.
Many lamp accidents have been caused by moving down the wick, in order to
extinguish the flame, such a distance that the oil becomes ignited or an explosion
occurs.
Referring to the drawings
:-
Figure 1 is an elevation, partly in section, of the burner, gallery, and attachments
of an ordinary oil lamp with my device attached thereto, showing the device out of

page_text: Figure 2 is an elevation of a portion of Figure 1, showing the device in action,
closing the mouth of the wick tube.
Figure 3 is a perspective view of my device detached.
Like letters indicate corresponding parts in the Figures.
In carrying out the invention, the upper portion of the wick tube A is surrounded
or partly surrounded with an extinguisher casing or tube B, preferably of metal,
fitting it preferably very loosely. prefer to make it of the form shown in Figure 3 ;
the device in this case does not entirely surround the wick tube A, but does so to an
extent sufficient to retain it in position on the tube.
The lower face b, which rests on the perforated plate C surrounding the wick tube,
is chamfered, so that the device will not lie quite vertical and parallel with the wick
tube A. The upper face of the device is partly covered by a lip ¹, so that when the
extinguisher is resting on its chamfered face, the said lip is over the wick, and
preferably entirely covers the opening to the wick tube A, as in Figure 2.
When the wick is raised by the mechanism usually employed, it pushes aside the
extinguisher, as seen in Figure 1, or, if preferred, it may be drawn aside by hand, or
an eye or small handle may be provided for pulling it aside, thus permitting the wick
to be moved up.
When the wick is turned down for the purpose of extinguishing the flame, the
extinguisher casing or tube B will, owing to its sloping or chamfered face b, fall back
into its normal position, and the lip b¹ will cover the wick or wick tube A, and thereby
instantly extinguish the flame, before the wick is moved down sufficiently to cause
the flame to ignite the oil.
If tho lamp is upset, the tube or casing A slides over the wick and extinguishes the
light.
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 extinguisher for lamps, consisting of a bent piece adapted to loosely embrace
the wick tube, and having an inwardly projecting lip at its upper end normally resting
against the wick, and an inclined or chamfered part at its lower end upon which it is
supported, in such a manner that, when the wick is lowered, the device has a
tendency to assume such a position that the said lip will cover the mouth of the wick
tube, substantially as described.
2. The improved automatic extinguisher for lamps, substantially as described and
shown.
