I, WILLIAM SANDBROOK of Ebbw Vale in the county of Monmouth, Ironmonger do
hereby declare the nature of this invention to be as follows:-
My invention relates to a simple and inexpensive device for extinguishing the flame
of paraffin or other oil lamps.
My improved extinguisher consists of a blade of tin or other metal extending the
width of the wick-tube and mounted upon the free end of a spring arranged at the
centre of one side of the said tube. The other end of the said spring is secured to a
band which fits around the wick-tube, so that the extinguisher can be readily fitted
upon or removed from the said tube. The said band and spring may be formed by
bending a single piece of wire into the requisite form. The spring normally keeps
the metal blade away from the wick-tube but parallel with the side thereof. A stud
or wire passes from the back of the spring, through the burner. By pushing the said
stud or wire the blade is forced over the wick, the parts being so arranged that the
said blade is then close to the top of the wick-tube and the flame is thus extinguished.
Or the extinguisher may be pulled over the wick-tube by a wire connected to it and
passing through the burner in front of the extinguisher.
My improved device may be permanently attached within the burner, in which case
the band fitting around the wick-tube may be dispensed with and the spring fixed to
the side of the wick-tube or secured in any other suitable manner.
I may use two blades carried by two springs, one on each side of the burner, the
said blades meeting each other over the wick-tube when the lamp is extinguished.
For annular or argand burners I make the said blades each in the form of a half ring.
The band surrounding the wick-tube and the springs may in these cases also, be formed
of a single piece of wire, or the springs may be fixed within the burner as above
mentioned.
Either of the forms of my improved extinguisher above described may be operated
by levers, pushes or any other suitable device or devices.

page_text: I, WILLIAM SANDBROOK of Ebbw Vale in the County of Monmouth, Ironmonger,
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, reference being had to the accompanying drawing forming a part of this
specification:-
:-
My invention relates to a simple and inexpensive device for extinguishing the flame
of paraffin or other oil lamps.
My improved extinguisher consists of a blade or plate of tin or other metal large
enough to cover the top of the wick-tube, or of a metal cap adapted to be drawn or
pushed over the top of the wick-tube the said blade or cap being mounted parallel
with the side of the wick-tube in such a manner that, when desired, it can be drawn
or forced over the wick-tube and the flame extinguished. The said plate or cap may
be mounted upon the free end of a spring arranged at the centre of one side of the
wick-tube, and the other end of the said spring be secured to a band which fits around
the wick-tube, so that the extinguisher can be readily fitted upon or removed from the
said tube. The said band and spring may be formed by bending a single piece of
wire into the requisite form. The spring normally keeps the metal blade or cap away
from the wick-tube but parallel with the side thereof. A stud or wire passes from
the back of the spring through the burner. By pushing the said stud or wire the
blade or cap is forced over the wick, the parts being so arranged that the said blade or
cap is then close to and covers the top of the wick-tube and the flame is thus
extinguished. Or the extinguisher may be pulled over the wick-tube by a wire
connected to it and passing through the burner in front of the extinguisher.
My improved device may be permanently attached within the burner, in which case
the band fitting around the wick-tube may be dispensed with and the spring fixed to
the side of the wick-tube or secured in any other suitable manner.
I may use two blades or caps carried by two springs one on each side of the burner,
the said blades or caps meeting each other over the wick-tube when the lamp is
extinguished. For annular or argand burners I make the said blades or caps each in
the form of a half ring. The band surrounding the wick-tube and the springs may in
these cases also be formed of a single piece of wire or the springs may be fixed within
the burner as above mentioned.
Or the blade or cap may be mounted on the top of vertical arms pivotted to
the wick-tube or burner, one of the said arms forming a crank-lever by which the
cap or blade is drawn over the burner.
Either of the forms of my improved extinguisher above described may be operated
by levers, pushes or any other suitable device or devices.

Figures 5 and 6 áre front and back views of a portion of a lamp-burner fitted
with a modified form of my improved extinguisher, showing the top of the wick-
tube covered by the extinguisher.
Figure 7 is an end view of the same also showing the wick-tube covered by the
extinguisher and figure S is a similar view with the extinguisher thrown back from
the wick-tube.
Like letters indicate like parts in all the figures.
The extinguisher shown in figures 1, 2, 3 and 4 consists of a cap a stamped or
otherwise formed from brass or other suitable metal. The said cap is of such a
length as to extend the width of the wick-tube and consists of a top plate a¹ and
a back plate a² at right angles thereto, the back plate curving around the ends of
the cap as shown. The front of the said cap is open so that the said cap can be drawn
or pushed horizontally over the top of the wick-tube. The said cap is so formed
and arranged that when over the wick-tube its top-plate fits over and closes the top
of the said tube and its back-plate and ends fit against the back and ends of the said
wick-tube. The said cap a is unounted parallel with the side of the wick-tube upon
a wire frame which may be formed of a single piece of wire bent into the required
form. The lower portion of the said wire is bent around the wick-tube as at c
forming a loop or band round the wick-tube so that the extinguisher can be readily
fitted upon or removed from the said wick-tube if desired. One end of the wire is
hent as at c to set against the back of the wick-tube and the other end of the wire is
bent outward and upward as at c forming a spring for the extinguisher. From the
top of the spring c² the wire is bent around and downward in front of the wick-tube,
forming a frame d between the sides of which the cap a is soldered in such position
that the spring normally keeps the said cap off or away from the wick-tube b. The
front of the frame d is formed with a loop d to which is connected a rod e passing
through the burner to the outside. By pulling the said rod the cap a is drawn over
the wick-tube as shown in figures 1, 2 and 3 and the flame of the lamp is
extinguished, the parts being so arranged that the top of the cap is then close to and
covers the top of the wick-tube. When the rod e is released the spring throws the
cap a back from the wick-tube as shown in figure 4 and the lamp is
re-lighted.
ready to be
The modified form of my extinguisher shown in figures 5, 6, 7 and 8 consists of a
capf having a top-plate for covering the top of the wick-tube b and a back-plate f
which sets against the back of the said wick-tube, the said top and back plates being
formed in one piece with or mounted upon arms g which, when the extinguisher is
over the wick-tube, extend down the sides of the said wick-tube as shown in figure 7.
The extinguisher is pivotted to the wick-tube by a rod soldered to the lower
portion of the front of the said wick-tube, the said rod passing through holes in
the arms g of the extinguisher so that the said extinguisher turns freely upon the said
rod. The lower end of one of the arms g projects forward, forming a crank-lever as
at g and to the said portion g' is linked a rod i passing downward through the
burner and carrying on its outer end a cord j by which the extinguisher is operated
from the outside of the lamp. By pulling the said cord the extinguisher is raised
into the position shown in figure 7 and the lamp is extinguished, the top-plate of the
cap being then over and close to the top of the wick-tube. When the cord j is
released the weight of the extinguisher being to the rear of its pivots on the rod h,

page_text: the said extinguisher will fall into the position shown in figure 8 and the lamp be
ready for re-lighting. Or if necessary a spring may be provided for throwing the
extinguisher off the wick-tube when it is released.
In applying my invention to an annular or argand burner I use two caps each in
the form of a half circle, mounted on opposite sides of the wick-tube so that when the
said caps are thrust or pulled over the wick-tube, they meet each other over the said
wick-tube, covering the upper end thereof and extinguishing the flame.
I do not limit myself to the details and arrangements above described as both the
form of the cap and the means for operating the same may be varied without departing
from my invention. Thus in place of the caps a or fI may use simple plates or blades
of metal, similar to the top-plate of the said caps, of sufficient size to cover and close
the top of the wick-tube. The said plate or plates or cap or caps may also be mounted
within the burner at the side of, or to the side of the wick-tube, detachably or
otherwise in any other suitable manner which will permit of the said plate or plates,
cap or caps, being operated so as to close and uncover the wick-tube in the manner
herein described and instead of the means herein described and shown for operating
the extinguisher I may use pushes or levers for bringing the extinguisher over the
wick-tube and springs or other suitable means for withdrawing the extinguisher from
over the said wick-tube.
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 —
An extinguisher for extinguishing the fame of a paraffin or other oil lamp,
constructed and arranged substantially as herein set forth.
