CHARLES BALHATCHET PEDLAR, of Nailsworth, in the County of Gloucester,
Ironmonger's Assistant. IMPROVED MEANS OF EXTINGUISHING HYDRO-CARBON
"
AND OTHER LAMPS AND LAMP-STOVES."
This Invention consists in an arrangement by which hydro carbon and other
lamps and lamp-stoves can be instantly and completely extinguished by the act of
lowering the wick.
This arrangement consists of a flap or piece of flat metal which is caused to press
gently against the wick, and as the wick is lowered the said flap passes over the
top of the wick and so stops off the issue of gas from the wick to the flame.
It is obvious that this arrangement may be carried out in several different
methods, as for instance, a portion of the wick tube may be cut away and a flap or
piece of flat metal inserted in its place, working easily on two pivots, or the flap
may work inside the wick case (without any part thereof being cut away, so that
when the wick is raised up for burning it raises or pushes back the flap and causes
it to become perpendicular with the side of the wick case.
The flap is so adjusted either by weight or by a spring acting upon it that when
the light is no longer required and the wick is turned down the flap either falls by
the weight or is forced by the spring from its perpendicular position to a diagonal
or even horizontal position if required. Its top edge will then rest upon the
opposite side of the wick case and sufficiently exclude thepassage of gas as at once

page_text: to extinguish the light.. Or in place of the flap working on two pivots it may be
so constructed on or with a spring that the raising of the wick forces the flap up or
back sufficiently beyond the opening of the wick case as not to interfere with the
burning of the lamp, and on the wick being lowered the spring presses the flap
over and effectually extinguishes the lamp.
An important feature in this Invention is that the flap or extinguisher is raised
by the mere ascent of the wick when forced up by the ordinary pinion wheel or
otherwise for lighting the lamp, and as the flap is constantly pressing against the
wick it is at once lowered, and so extinguishes the lamp when the wick is turned
down.

CHARLES BALHATCHET PEDLAR, of Nailsworth, in the County of Gloucester,
Ironinonger's Assistant. "IMPROVED MEANS OF EXTINGUISHING HYDRO-CARBON
AND OTHER LAMPS AND LAMP STOVES."
My Invention consists in an improved arrangement of apparatus by which
hydro-carbon and other lamps and lamp stoves can be instantly and completely
extinguished by the act of lowering the wick.
This arrangement of apparatus consists of a flap or piece of flat metal which is
caused to press gently against the wick, and as the wick is lowered the said flap
passes over the top of the wick and so stops off the issue of gas from the wick to
the flame.
It is obvious that this arrangement may be carried out in several different
methods, as for instance,-
A portion of the wick tube may be cut away and a flap or piece of flat metal
inserted, working easily on two pivots; again, the flap may work inside the wick
case, without any part thereof being cut away, so that when the wick is raised up
it raises or pushes back the flap-and-causes-it-to-become-perpendicular_with the
side of the wick case. The flap should be so adjusted, either by weight or by a
spring acting upon it, that when the light is no longer required and the wick is
turned down the flap either falls by the weight or is forced by the spring to a
diagonal or even horizontal position if required. Its top edge will then rest upon
the opposite side of the wick case and sufficiently exclude the passage of gas as at
once to extinguish the light.
In practice it will be found that the modification first referred to and shewn in
Figures 2, 3, and 4 will afford special advantages, as when the wick d is lowered the
flap b, which should be inclined at a moderate angle for the purpose described, presses
against the partly consumed top of the wick d, removing the upper burnt edge,
which falls down the inclined back of the flap b, and so while extinguishing the
flame the drawing down of the wick acts against the upper edge and turns it off,
the burnt parts fall down and leave the wick d ready trimmed for subsequent
ignition.
Or, in place of a flap working on two pivots, or on its bottom edge, or some
equivalent for a hinge, the extinguisher may be constructed of a very fine spring
only, the width of the wick case, attached to the wick case or other portion of the
burner, and so arranged that the raising of the wick forces the spring sufficiently
back or beyond the opening of the wick case as not to interfere with the burning
of the lamp, and on the wick being lowered the spring closes over and effectually
extinguishes the lamp.
And in order that my said Invention may be more readily understood, I will
proceed to describe the same with the aid of the annexed Drawings, wherein the
same letters of reference indicate similar parts in all the Figures.
Figure 1 is an outside elevation of a hydro-carbon burner with my improved
extinguisher applied thereto, in which it will be seen that my improvements in no
way interferes with the sightlyness or general appearance of the burner.

In this Figure, the Hap b which is hinged at 61 and b' is shewn up or perpen-

wick d is raised to the proper height for ignition.
Figure 3 is a similar view to that shewn in Figure 2 but with the flap b down or
in its inclined position, namely, that which it occupies when the wick has been
lowered. The spring e which is attached to the lower part of the wick tube c by its

Figure on the upper part of the wick d, being lowered into the tube. Fig. 4 is a
transverse action of the burner on the line A, B.
Having now described the nature and object of my said Invention, and the
method of carrying the same into effect, I wish it to be understood that I do not
confine myself to the precise details herein set forth and illustrated, but that
what I claim is,―
First. The respective combinations of parts forming respectively my improved
arrangements of mechanism for extinguishing the flame of hydro-carbon and other
lamps and lamp stoves, substantially in the manner and for the purposes herein-
before described, and shewn respectively in Figures 1, 2, 3, and 4 of the Drawings
hereunto annexed.
Second. The use of apparatus applied to burners for extinguishing the flame of
lamps and lamp stoves wherein the wick itself on being forced up to the ordinary
winder opens or pushes back a metal flap or spring, and the lowering of the wick
below the top of the cover causes it to be closed by means of a spring, or weight, or
other equivalent, substantially as herein before described and shewn on Drawings.
In witness whereof, I, the said Charles Balhatchet Pedlar, have hereunto
set my hand and seal, this Fourth day of June, in the year of our Lord
One thousand eight hundred and seventy nine.
