Improvements in Extinguishers for Hydro-carbon and other Lamps.
I, FRANCIS ROBERT BAKER of Arcade Chambers Snow Hill Birmingham in the
County of Warwick, Engineer, do hereby declare the nature of this invention
to be as follows :-
My invention consists of the following improvements in extinguishers for hydro-
carbon and other lamps; and the principal object of my invention is to so simplify
the construction and manufacture of the said extinguishers, that they can be produced
at a much less cost than those of the ordinary kind; so that by simplifying and
reducing the cost of manufacture, the commonest lamp burners now made, can
he provided with means of extinguishing without materially enhancing the cost
of a lamp so provided.
In carrying out my invention, I take a single wick lamp burner, having within
its body an inverted cone cup, which surrounds the wick tube about its middle, and
on the two opposite sides of the said wick tube, I arrange two limbs which proceed
upwards from the base of the cone before named; and these limbs or half extin-
guishers have at their upper extremities half box like formations, which when
brought together at the top of the wick tube, they embrace and enclose the burning
part of the wick, and thereby extinguish the flame.
Each half of the extinguisher consists of a flat strip of sheet metal having a tongue
like piercing cut out longitudinally from its middle, which is bent outwardly at
right angles to the other part, so as to form an arm or pusher, by which means
the extinguisher is closed.
The lower end of the limb below the pierced or cut out part, is turned hook like
under the edges of the cone, so as to secure the said extinguisher at its base, to the
burner.
The top end of the blank or sirip of spring metal forming the limb to the half
extinguisher is made box like on the square, but with its lower side removed to
admit of the two half boxes, constituting the extinguisher, missing the wick tube.
The half box like end is of a depth about equal to half the breadth of the wick
tube, and a little below this last named terminal part, the limb of the appliance
or half extinguisher is cranked inwardly, in order to bring the extinguisher part
over and around the flame and burning wick part.

page_text: The pusher arm extends through a hole or opening in the burner body, and
when the said extinguisher is fixed in position, it tends to spring outwardly, for the
bringing of it back to its normal position.
Two of the half extinguishers hereindescribed, are placed on the two opposite sides
of the wick tube, so that the arms come out of the sides of the burner in opposite
directions.
To. extinguish a lamp, press in opposite directions by the thumb and finger, the
two protruding or standing out pusher arms; by doing so, the extinguisher limbs
are brought closer together, with the edges of the box like formation at the upper
part, in juxta position, and enclosing the top of the wick, thereby extinguishing the
Hame of the lamp.
After extinguishing, the pusher arms are liberated, when the halves or the two parts
of the extinguisher expedient automatically open out (by the springiness of the
metal) from the wick and wick tubes, so as to be out of the way when the lamp
is burning.
Thus the act of pinching together the pusher arms between the thumb and finger,
extinguishes the lamp, while the liberation thereof, takes the parts back to ilieir
normal positions.
Instead of the limbs of the extinguisher lying in a vertical direction, the arms
themselves may be made to constitute the limbs, and upon their inside edges,
half box extinguishers are secured.
The arms are made somewhat in the form of a long nursery pin without a catch; so
that the gripping together of the arms which protrude through the sides of the
burner effect the bringing together of the extinguisher half boxes, which may
be made to overlap each other, or be presented edge to edge in a parallel direction.
The coil at the back end of the arms takes the arms back to their normal positions
on being liberated.
Or guides may extend across the burner body upon which the extinguisher halves
with pusher stems move in a parallel direction. Interposed coiled springs take the
parts back to their normal positions on the pusher being liberated.

COMPLETE SPECIFICATION.
Improvements in Extinguishers for Hydro Carbon and other Lamps.
I, FRANCIS ROBERT BAKER of Arcade Chambers Snow Hill Birmingham in the
County of Warwick Engineer, 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:
My invention consists of the following improvements in extinguishers for hydro
carbon and other lamps; and the principal object of my invention is to so simplify
the construction and manufacture of the said extinguishers, that they can be produced

page_text: at a much less cost than those of the ordinary kind; so that by simplifying and
reducing the cost of manufacture, the commonest lamp burners now made, can be
provided with means of extinguishing, without materially enhancing the cost of
à lamp so provided.
In carrying out my invention, I take a single wick lamp burner, having within
its body, an inverted cone cup, which surrounds the wick tube about its middle; and
on the two opposite sides of the said wick tube, I arrange two limbs, which proceed
upwards from the base of the cone before named and these limbs or half extin-
guishers, have at their upper extremities, half box like formations, which when
brought together at the top of the wick tube, they embrace and enclose the burning
part of the wick, and thereby extinguish the flame.
Each half of the extinguisher, consists of a flat strip of sheet metal, having a
tongue like piercing cut out longitudinally from its middle, which is bent outwardly
at right angles to the other part, so as to form an arm or pusher, by which means
the extinguisher is closed.
The lower end of the limb below the pierced or cut out part, is turned hook like
under the edges of the cone, so as to secure the said extinguisher at its base,
to the burner.
The top end of the blank or strip of spring metal forming the limb to the half
extinguisher, is made box like on the square, but with its lower side removed,
to admit of the two half boxes, constituting the extinguisher, missing the wick tube.
The half box like end is of a depth about equal to half the breadth of the wick
tube, and a little below this last named terminal part, the limb of the appliance
or half extinguisher is cranked inwardly, in order to bring the extinguisher part over
and around the flame and burning wick part.
The pusher arm extends through a hole or opening in the burner body, and when
the said extinguisher is fixed in position, it tends to spring outwardly, for the
bringing of it back to its normal position:
Two of the half extinguishers herein described, are placed on the two opposite
sides of the wick tube, so that the arms come out of the sides of the burner in opposite
directions.
To extinguish a lamp, press in opposite directions by the thumb and finger, the
two protruding or standing out pusher arms; by doing so, the extinguisher limbs
are brought closer together, with the edges of the box like formation at the upper
part, in juxta position, and enclosing the top of the wick, thereby extinguishing
the flame of the lamp.
After extinguishing, the pusher arms are liberated, when the halves, or the two
parts of the extinguisher expedient automatically open out, (by the springiness
of the metal) from the wick and wick tubes, so as to be out of the way, when the
lamp is burning.
Thus the act of pinching together the pusher arms between the thumb and finger,
extinguishes the lamp, while the liberation thereof, takes the parts back to their
normal position.
The arms of the extinguisher half boxes, instead of being disposed in a vertical
plane, may lie and open out in a horizontal direction.
I will now proceed to describe with reference to the accompanying Drawing,
the manner in which the same is to be performed.
Figure 1 represents in side elevation, partly in vertical section, a lamp burner,
provided with extinguishing mechanism, constructed according to my invention,
(extinguisher shown out of use). Figure 2 represents in elevation, the same, with
the extinguisher in use; or with the half extinguisher boxes closed upon the flame,
and burning part of the wick for extinguishing. Figure 3 is a vertical section
of the extinguisher as in figure 2. Figure 4 is a side elevation of the extinguisher
with the upper portion of the lamp burner removed. Figure 5 is a plan of figure 1.
The same letters of reference indicate corresponding parts in the several figures.
a is the body part of the burner, and the cone with flame slit, and which said parts
are of the ordinary construction. ⚫ c are extinguisher half boxes, placed at the upper

page_text: extremities of cranked or bent spring arms d, d, and having connected therewith,
pushers, or pusher arms e, e, by which means, the arms d, which proceed. upwards
from the base of the body of the lamp, are closed for extinguishing.
In order to give to the arms d the necessary springy action for their automatic
opening out, after closing or extinguishing, I secure the lower ends d2 of the said
arms, under the block or cone f, which is at the base of the body of the burner,
and surrounds the wick tube marked g, and through which, the wick h passes.
The pusher arms e e, spring arms or limbs d and extinguisher half boxes cc,
are cut out of, and shaped from a single piece of sheet metal, although the said parts
may be made separately, and attached together by soldering or otherwise.
The pusher arms e e, pass through holes a² in the burner body.
To extinguish a lamp, press the pusher arms e e in opposite directions, by the
thumb and finger, when the extinguisher half boxes c, c, are brought together, and
closed upon the end of the wick tube and wick, thereby extinguishing the flame
of the lamp.
After extinguishing, the pusher arms e, e, are liberated, and the extinguisher
half boxes c and arms d, with pushers e, automatically open out as shown at figure 1.
The extinguisher arms d instead of being disposed and working vertically, they
may be disposed and work horizontally.
The extinguisher, may be applied to lamps provided with more than one wick.
Although I have described and represented the arms, carrying the wick boxes,
as spring arms, yet they may be made out of stiff metal, and hinged at their lower
ends to the bottom of the burner body, or the wick tubes, and opened outwardly,
by springs, interposed between the parts, or at the back of the arms.
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 :-
First-Operating lamp extinguishers, by a pusher action, which on being liberated
after extinguishing, automatically flies open or divides itself away from the wick, and
wick tubes, substantially as described and set forth.
Secondly In a lamp extinguisher, consisting of spring arms or limbs d, d,
carrying at their tops or top ends, half extinguisher boxes c, c, which are brought
together for extinguishing, by lateral side pushers e, e, passing through holes a²
in the sides of the burner body, and which said arms or limbs d, d, are secured
at their lower ends to the lower part of the said burner body, whereby the arms
on being released, after extinguishing, automatically fly open or expand outwardly,
substantially as described and illustrated.
Thirdly Making the arm d, d2, half extinguisher box c, and pusher e in one
piece, substantially as set forth.
