I JOHN WILLIAM BERNARD WRIGHT, of the firm of Wright and Butler, Limited,
Now John Street West, Birmingham in the county of Warwick Lamp Manufacturers
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction and arrangement of
lamps having circular wicks, and in which air is supplied to the interior of the flame,
through the burner, or its adjacent parts, to the lower end of the wick tubo, and thence
to the flame, and has for its object, cortain means whereby it may be readily
extinguished; which consist in providing and operating a sliding case, upon the
exterior of the wick tube, which is raised a required height to cut off the supply of
air, to the exterior of the flame, and in further attaching to the external sliding case,
by means of suspending rods, or their equivalents, a disc, at the bottom of the wick
tube, for the cutting off, of the supply of air entering the lower end of such wick
inner tube. Thus when the external case is raised a given height, the disc is also
raised up to the lower end of the inner tube, thus cutting off simultaneously the inner
and outer air currents, and thereby extinguishing the flame,. In order to economise
the space or depth in the air chamber, which supplies the inner tube, 1 may provide
that the disc shall only fall or travel a shorter distance than the external sliding case,
the suspending rods being arranged for such purpose.
The raising of the said sliding case, would be effected after the following manner.-
From the said sliding case, an arm would extend to the outside of, and below the
gallery, and terminate in a finger lift pioco, so that it may be raised vertically by
means of the finger, or thumb and finger; such arm or equivalent extension part,
passing through a slot, or slots in the side of the burner, provided for that purpose, in
which the upward and downward motion may take place.
Or, as will be obvious a lever inay be used to raise or lower the sliding case &c.,
similar to those in use for ordinary extinguishers upon flat wick burners.
Dated this 30th day of July 1888.

page_text: Improvements in Extinguishing Mechanism for Certain Circular
Wick Burners of Hydro Carbon and other Oil Lamps.
I JOHN WILLIAM BERNARD WEIGHT, of the firm of Wright and Butler, limited,
New John Street West, Birmingham, in the county of Warwick, Lamp Manufacturers
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:
This invention relates to improvements in the construction and arrangement of
lamps having circular wicks and in which for instance, air is supplied to the interior
of the flame, through the burner, or its adjacent parts, to the lower end or centre of
the wick-tube, and thence to the flame, by means of an air chamber communicating
with the exterior of the lamp, and extending thence to the lower end, contre, or other
part of the said wick tube; and has for its object, cortain means wheroby it may be
readily extinguished; which consists in providing and operating a sliding case, upon
the exterior of the wick tube, which is raised a required height to cut off the supply
of air to the exterior of the flame, and in further attaching to this external sliding
case, by means of suspending rods, or their equivalents, a disc, or other attach-
ment, at the bottom, centre, or other part of the wick tube, at which the air enters;
for the cutting off of the supply of air entering at such point to supply the interior of
the flame.
Thus, when the external case is raised a given height, the disc or other attachment
is also raised up to the lower end or other part of the inner tube, thus cutting off
simultaneously the inner and outer air supply currents, and thereby extinguishing the
flame. In order to economise the space or depth in the air chamber, which supplies
the inner tube, I may provide that the disc or other arrangement, shall only fall or
travel a shorter distance than the external sliding case, the suspending rods being
arranged for such purpose.
The raising of the said sliding case, would he effected after the following mannor:-
From the said sliding case, an arm would extend to the outside of, and below the
gallery, and terminate in a finger lift piece, so that it may be raised vertically by
means of the finger, or thumb and finger, such arm or equivalent extension part,
passing through a slot or slots in the side of the burner, provided for that purpose, in
which the upward and downward motion may take place.
Or, as will be obvious, a lever may be used to raise or lower the sliding case &c.,
similar to those in use for ordinary extinguishers upon flat wick burners.
I now proceed to more particularly show and explain how my invention may be
performed, having reference to the accompanying illustrative sheet of drawings, upon

page_text: gures win letters of reference, similar letters referring throughout the
soveral views to the same thing or part.
Fig. 1 illustrates this invention in sectional elevation.
Fig. 2 represents the mechanism in action, when the flame would be extinguished.
Figs. 3, 4 & 5, show details hereinafter explained.
a, is an air chamber carried from the lower part of the burner, is the wick tube
terminating in its depth at c, but further communicating with the oil reservoir for
supply, by moans of a small inlet or passage d.
Air currents for the support of combustion are supplied to the exterior of the flame,
through the perforations in the upper part of the body of the burner, as indicated by
the arrows e; while the air current for the same purpose, is conveyed to the interior
of the wick tube, through the perforations in the lower part of the body of the burner,
as indicated by the arrows f
Upon the upper end of the wick tube, I provide a sliding tube or case g, which is
free to move up and down for a certain distance.
Connected to this sliding case by means of the suspending rods h, h, is a
bottom stop plate or disc i, sco also Fig. 3. These rods h,, may if desired,
be rigidly attached to the sliding tube g, in which case the amount of motion of the
plate i, would be equal to that of the sliding tube g, but inasmuch as it is not necessary
to give as much motion to the stop plate, as to the sliding case, and as it is desirous
to keep the bottom ends of the wicks as low down as possible in the oil vessel, I
provide that a part only of the motion of the case, shall be imparted to the stop plate.
Upon this sliding case g, are snugs j, which serve as guides, and also as lifters for
the rods h, h, the said rods having at their upper ends, heads or projections k,
(see Fig. 4).
Other guides may be provided, if desired, for the suspending rods as seen at l.
Again. From the sliding case g, an arm m extends to the outside of the burner,
torminating in a suitable lift pieco n, a slot being made in the burner body, to allow
of an upward and downward motion of such arm.
Instead of this direct lift however, it will he obvious I may use a lever for raising
the sliding case &c. (very similar to those used in combination with ordinary
extinguishing apparatus of flat wick lamps) as illustrated, for instance, in Fig. 5;
o being the lever, working upon fulcrum p, and q being a projection upon the sliding
case 9, against which the lever lifts.
Thus the action of the mechanism would be somewhat as follows:-
In Fig. 1, upon lifting the arm m, the sliding case alone is raised, until the snugsj,
reach the heads or projections k, upon the suspending rods h, h, when both the outer
case 9: and the stop plate i, would rise together until the plate i, reaches the bottom of
the wick tube, and thereby cuts off the supply of air to the interior, and at the
same time the outer case has reached a sufficient height to cut off the supply of air
to the exterior, as seen in Fig. 2.
Although I have illustrated this invention as applied to lamps wherein the central
portion of the circular wick tubo is confined within the oil vessel, it will be obvious
that in the case where metallic reservoirs are used, such an arrangement, if desired,
may be readily modified to operate, where the said central portion is carried below
such reservoir, in which case a tubular passage or passages, or equivalent device,
would be formed through the said reservoir, through which the rod or rods &c. may
pass, to suspend the stop plate at the lower end of the tube.
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. The combination with an outer sliding extinguisher case g, of the stop plate i, or
its equivalent, for the purpose of simultaneously cutting off the internal and external
air supply to the flame of circular wick lamps, and thereby extinguishing it, constructed
and operating substantially as hereindescribed and illustrated upon the drawings, in
Figs. 1. 2. 3 & 4.

page_text: 2. The modification of operating in combination with the parts constituting this my
extinguishing mechanism, of the lever o as a modified method of operating the same,
substantially as hereindescribed and illustrated in part upon Fig. 5, such other parts
as are necessary to complete the combination, being illustrated in Figs. 1 to 4
inclusive.
3. The general combination and arrangement of the parts constituting the
extinguishing mechanism for circular wick lamps, constructed and operating
substantially as hereindescribed.
