We GEORGES JUSTIN JOSEPH LEGRAND Engineer of 343, Holloway Road
London N. and GEORGE PRICE Salesman 85 Weymouth Terrace, Hackney Road
London N.E. do hereby declare the nature of this invention to be as follows:-
A new or improved form of lamp extinguisher to act automatically and otherwise
by the means of a rod passing preferably through the central draught tube of a
lamp, or through other but draught tubes to which rod or rods the flame spreader
is attached either by the means of a screw thread or by a bayonet joint or other
means so as to be easily detachable therefrom; the rod passes down the tube
through some suitable guides and at its lower extremity it has a ring, or eye or
hole through which is passed the end of a small round shape chain or cord or
flexible material metal or substance; this in turn is attached to a weight of
suitable form and metal which rests upon the base of the lamp such base being
preferably heavy to help balance the weight of the lamp and to prevent same easily
turning over the base of the lamp is preferably saucer shaped or funnel or V shaped and
slightly scooped out at centre to hold the weight therein should lamp be but slightly
oscillated, said weight may run easily between two such saucers, the top one having an
aparture to allow cord, etc., attached to the weight to pass through; when the lamp
falls or is thrown the weight slips out of the scoop of the saucer and falling in any
direction, with the fall of the lamp, it slides or falls to end of the base pulling on
the cord, etc., which in turn pulls down the rod with Hame spreader attached and
forcing this down tightly upon the burning wick puts it out on account of cutting
off the supply of air thereto from the central draught tube and the outside
encircling wick tube; the shape of flame spreader and extinguisher is so made with
recess or other form as to well cover the wick and tubes when down over them;
the rod carrying the spreader is hollow or a thin strong flat or other rod is used
and air access is allowed through the spreader so as to mingle with the flame on
lamp being alight and the spreader has a cap or other fitting through which the
air is allowed to pass, between bars or through holes to mingle with the flame thus
consuming the smoke and fumes in the chimney.
To the rod is attached preferably down near the base a spindle with a knob
fitted to the rod rigidly through a vertical cut or slet formed in the foot of the
lamp, the knob is for the purpose of pulling down the spreader and extinguishing
the lamp by hand, the cut or slot in the foot of the lamp may be protected by a
shield so that when taking hold of the lamp the hand is out of contact with the
knob and allows it full play should the person carrying the lamp fall with it;
several such pull down knobs can be fitted to the lamp and levers or other mechanical
parts may be used to actuate the spreader extinguisher before described. A cut or
slot is formed in stand or base of lamp to catch the knob thus holding spreader
over the wick putting out flame.
A spring or weighted lever is used to push back the rod and the spreader from
off the wick when the lamp is replaced in a vertical position and the weight has
taken its place in centre of the scoop in the saucer shaped base plate; the spring
is coiled around the rod and abuts against a pin placed through the rod. One end of
spring rests upon a guide of the said rod.

page_text: Other ways of working the spreader may be employed such as having the base
of lamp with a cone shape at centre the point being upwards, a weight shaped to fit
such cone would be used and to the end of weight would be attached a cord the
other end would be attached to a fixed point above, on lamp being upset in any
direction the weight would leave the cone and engaging between the levers ends of
lazy tongues would cause these to open out and close the rest of the lazy tongues
to which the rod attached to the spreader is attached thus bringing it down upon
the burning wick and putting it out, or a suspended weight when out of the vertical
line can operate levers which will bring down the spreader or by other mechanical
means to effect the same object.
Instead of the central draught tube any other tube placed inside or outside of
the reservoir of the lamp in combination with the weights and mechanical parts as
explained can be used, and such mechanisms may be used also with one or more
flat wick burners actuating flaps or with any combination lamp, heating or oil
cooking stove, etc., etc.
To prevent the tap of the reservoir getting heated as the oil gets lower in it and
the gases generate, a source of danger, a layer of wool or a cover of non heat
conducting material is placed over the top of reservoir of the lamp or a cover of
any material metal or substance is placed over the reservoir sufficiently high to
allow of air circulating between the two thus keeping the reservoir and the oil
always cool the admission of the air can be through holes or cuts in the rim of the
protector or anti heat conductor and such protector can be made highly ornainental
and with the rim projecting out all around the lamp so as to receive the shock and
break the fall of the lamp in case of accident.
The side oil filler would be fitted with a flap or other valve or a cone would be
arranged to contain a weighted round ball so that the air admitting orifice would
be closed and prevent oil running out should lamp fall.
Lamps would preferably be made of soft or malleable metal such as copper
brass zinc, etc., etc., but could also be made of hard metal or annealed metal or of
any other material or substance.
In combination with the above described we would mark our oil level indicator
systems Patent No. 19521 of 1894 dated October 13th.

Improvements in Lamps, Stoves, and the like, and in Extinguishing
Apparatuses for the same.
We, GEORGES JUSTIN JOSEPH LEGRAND, of 343 Holloway Road, in the
County of London, Engineer, and GEORGE PRICE, Salesman, of 85 Weymouth
Terrace, Hackney Road, also in the County of London, 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 :-
A new or improved form of lamp extinguisher to act automatically and otherwise
by the means of a rod passing preferably through the central draught tube of a
lamp, or through other but draught tubes to which rod or rods the flame spreader
is attached either by the means of a screw thread or by a bayonet joint or other
means so as to be easily detachable therefrom the rod passes down the tube through
some suitable guides and at its lower extremity it has a ring or eye or hole through

page_text: which is passed the end of a small round shaped chain or cord or flexible material
metal or substance; this in turn is attached to a weight of suitable form and metal
which rests upon the base of the lamp, such base being preferably heavy to help
balance the weight of the lamp and to prevent same easily turning over, the base
of the lamp is preferably saucer shaped or funnel or V shaped and slightly scooped
out at centre to hold the weight therein should lamp be but slightly oscillated said
weight may run easily between two such saucers the top one having an aperture to
allow cord &c. attached to the weight to pass through, or saucer can be formed in
the top part of the lamp; when the lamp falls or is thrown the weight slips out of
the scoop of the saucer and falling in any direction with the fall of the lamp it
slides or falls to end of the base pulling on the cord &c., which in turn pulls down
the rod with flame spreader attached and bringing this down nicely upon and over
the burning wick puts it out on account of cutting off the supply of air thereto
from the central draught tube and the outside encircling wick tube; the shape of
flame spreader and extinguisher is so made with recess or other form as to well
cover the wick and tubes when down over them; the rod carrying the spreader is
hollow or a thin strong flat or other rod is used and air access is allowed through
the spreader so as to mingle with the flame on lamp being alight and the spreader
has a cap or other fitting through which the air is allowed to pass, between bars
or through holes to mingle with the flame thus consuming the smoke and fumes in
the chimney.
To the rod is attached, preferably down near the base a spindle with a knob
fitted to the rod through a vertical cut or slot formed in the foot of the lamp the
knob is for the purpose of pulling down the spreader and extinguisher the lamp by
hand the cut or slot in the foot of the lamp may be protected by a shield so that
when taking hold of the lamp the hand is out of contact with the knob and allows
it full play should the person carrying the lamp fall with it; several such pull
down knobs can be fitted to the lamp and levers or other mechanical parts may be
used to actuate the spreader extinguisher before described (a cut or slot is formed
in stand or base of lamp to catch the knob thus holding spreader over the wick
putting out flame.
A spring or weighted lever is used to push back the rod and the spreader from
off the wick when the lamp is replaced in a vertical position and the weight has
taken its place in centre of the scoop in the saucer shaped base plate; the spring
is coiled round the rod and abuts against a pin placed through the rod one end of
spring rests upon a guide of the said rod.
In order that our invention may be more easily understood and carried into
practical effect we will now describe the same by the aid of the accompanying
drawings in which
Fig. 1 is a sectional elevation of an ordinary lamp having a central draught tube
and circular burner,
Fig. 2 is a sectional elevation of a duplex burner,
Fig. 3 is a sectional elevation of a single flat wick burner, and
Fig. 4 is a sectional elevation of a duplex oil stove.
As illustrated in Fig. 1 the burner is constructed as heretofore except that the
spreader a is formed as shown and is mounted on the upper end of a rod b which
rod is free to slide through supports e situated in the central draught tube d of the
lamp.
To the lower end of this rod is connected one end of a cord, chain, or the like
having secured to its opposite free end a weight g arranged to roll between the
saucer or otherwise conveniently shaped surfaces h on the lamp base, when said
lamp is partly or wholly inverted as for instance when upset, but which normally
occupies the position shown in full line.
The rod bis normally held, so that the spreader a occupies its usual position, by
a spring arranged between a projection on said rod and one of its supports c.
When however the weight 9 is caused to roll from its central position as for
instance as shewn in dotted lines, this movement results in the rod 6 being pulled

page_text: down against the pressure of the spring 7 and the spreader a so brought down on
and over the wick as shown in dotted lines, extinguishing the flame.
To permit of the lamp being extinguished when required one or more arms such
as m projecting from the rod through slots in the stem or other portion, of the
lamp may be provided, so permitting of said rod being operated independently of
the weight.
The slot in which said arm slides may have a recess n formed in one side to
permit of said arm being secured when forced down, whilst a shield o may be
provided to prevent the arm coming in contact with the hand when the lamp is
being held.
It will also be obvious that other analogous or equivalent ways of working the
spreader may be employed such as having the base of lamp with a cone shape at
centre, the point being upwards, a weight to fit such cone would be used and to
the end of weight would be attached a cord, the other end would be attached to a
fixed point above, on lamp being upset in any direction the weight would leave the
cone and engaging between the lever ends of lazy tongues would cause these to
open and close the rest of the lazy tongues to which the rod attached to the
spreader is attached thus bringing it down upon the burning wick and putting it
out, or a suspended weight when out of the vertical line can operate levers which
will bring down the spreader or by other mechanical means to effect the same
object.
In the case of lamps with duplex burners we preferably adopt the arrangements
shown in Fig. 2 from which it will be seen that in place of the spreader a (Fig. 1)
two hinged flaps or hoods p are employed these being connected by connecting
pieces to the rod b so that their upper ends will be forced over the burners when
said rod is drawn downwards. This rod bis arranged to work in a tube extending
completely through the reservoir of the lamp and is provided with a screw or
equivalent joint to permit of the lamp burner being removed.
When applying our invention to single flat wicked burners, the arrangement
shown in Fig 3 may be employed. In this case the flap or hood is arranged and
operates similarly to those employed in the burner described in reference to
Fig. 2. The joint in the rod b however is preferably a frictional one and to
obviate the necessity of revolving the burner when securing it in position it may
be fixed by a set screw s or the like.
The arrangement shown in Fig. 4 as applied to a duplex lamp or stove differs
somewhat from those above described. In this arrangement two flaps or hoods
are employed and these are connected by hinged pieces to the end of levers u
and these in their turn are connected by cords or other flexible couplings to a
roller so that should. the latter be revolved, the flaps or hoods will be operated
to extinguish the lamp. This roller also has the end of a cord wound round it
(the rod 6 Figs. 1, 2 and 3 being here dispensed with) so that it will be revolved
should the weight g be caused to roll.
These arrangements as will be well understood can be applied to any type of
lamps when desired.
To prevent the top of the reservoir getting heated as the oil gets lower in
it and the gases generated become a source of dauger, a layer of wool or a cover
of non-heat conducting material w (Fig. 1.) is placed over the top of the reservoir
of the lamp or a cover of any material metal or substance is placed over the
reservoir sufficiently high to allow of air circulating between the two thus keeping
the reservoir and the oil always cool. The admission of the air can be through
holes or cuts in the rim of the protector or anti-heat conductor and such protector
can be made highly ornamental and with the rim projecting out all around the
lamp so as to receive the shock and break the fall of the lamps in case of accident.
The wick tubes can be made partly of metal and partly of wood or other non-
conductors, top part being of the former and the lower part of the latter thus
rendering said tubes non-conductors. The burner may also be insulated by the
insertion of a layer of asbestos, or the like between it and the oil reservoir.

page_text: The side oil filler would be fitted with a flap or other valve or a cone would
be arranged to contain a weighted round ball so that the air admitting orifice
would be closed and prevent oil running out should lamp fall.
Lamps would preferably be made of soft or malleable metal such as copper,.
brass, zinc, &c., &c., but could also be made of hard metal or annealed metal or of
any other material or substance.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what.
we claim is :-
(1.) An oil lamp or stove fitted with a spreader, hood, flap, or the like, so that
it will be forced on to or over the flame of said lamp by a weight in the lower
portion of said lamp or stove and so extinguish it when the latter is partly inverted
