Improved Extinguishing Apparatus for Circular or Argand Burners
of Oil Lamps.
1, BENJAMIN JOSEPH BARNARD MILLS carrying on business under the firm or style
of Harris and Mills of 23 Southampton Buildings, in the County of Middlesex, Patent
Agent, do hereby declare the nature of this invention, a communication to me from
abroad by Anton Weisensee of Fulda, in the Empire of Germany, Lamp Manufacturer,
to be as follows:-
The invention has for its object improved arrangements of extinguishing apparatus
for oil lamps having circular or Argand burners.
According to one arrangement the extinguisher is formed in two parts, which, when
in the position required to extinguish the flame fit together and form a complete cap
extending entirely over the top of the circular burner and extending a short distance
down and around the same.
These two parts are provided with short dependent levers (one at each side) formed
at such reverse inclines or curves as to enable them to cross each other and to be pin
jointed in pairs to opposite sides of a ring fixed to the exterior of the burner tube; the
lower ends of these dependent levers are connected by links to a moveable tube or ring
which is connected to an actuating weighted rod which latter acts, and is controlled,
in a similar manner to that employed for a similar purpose in what is known as the
Shaftesbury lamp.
According to another arrangement the extinguisher is formed of three similar
segmental plates, which, when in position over the burner tubes, meet and form a
complete cover to the wick leaving a central circular hole coincident with the area of
the inner burner tube.
These segmental plates are hinged to a sliding ring fitting around the burner tube,
and they are each formed with a short lever, which is connected by a link to a lower
sliding ring attached to the actuating rod hereinbefore referred to which latter
however in consequence of its acting on the extinguisher in a contrary direction to that
above described is in the present case connected by a lever to a weighted actuating
od.

page_text: If desired the upper sliding ring, in its upward movement, may be caused to come
against a stop upon the wick tube which will have the effect of giving a more positive
motion to the segmental plates.
Or the segmental hinged plates of the extinguisher may be used without the short
levers, links and second ring before referred to in which case the actuating rod is
attached directly to the sliding ring to which the segmental extinguishing plates are
hinged and such sliding ring carries springs which when said ring is in its raised
position act to close the segmental plates over on to the top of the wick.
In connection with the two arrangements of extinguishing apparatus herein last
described a short tube may he employed placed within the inner wick tube and
connected to the operating rod or lever in such manner that it normally lies below the
edge of the wick but at the required time it rises and forms an abutment for the
segmental plates to close against by which means injury to the wick is avoided and
charred particles thereof are prevented from falling into the inner wick tube.
If desired the extinguishing apparatus herein described may be operated by hand
by means of the ordinary short lever or other means or any suitable automatic safety
device may be employed for that purpose.

Improved Extinguishing Apparatus for Circular or Argand Burners
of Oil Lamps.
I, BENJAMIN JOSEPH BARNARD MILLS carrying on business under the firm or style
of Harris and Mills of 23 Southampton Buildings, in the County of Middlesex, Patent
Agent, do hereby declare the nature of this invention, a communication to me
from abroad by Anton Weisensee of Fulda in the Empire of Germany, Lamp
Manufacturer, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The invention has for its object improved arrangements of extinguishing apparatus
for oil lamps having circular or Argand burners.
The extinguisher is formed in two parts, which, when in the position required to
extinguish the flame, fit together and form a complete cap extending entirely over the
top of the circular burner, and extending a short distance down and around the
same.
These two parts are provided with short dependent levers, (one at each side) formed
at such reverse inclines or curves as to enable them to cross each other, and to be pin
jointed in pairs to opposite sides of the exterior of the burner tube; the lower ends of
these dependent levers are connected by links to a moveable tube or ring, which is
connected to an actuating weighted or spring rod, which latter acts, and is controlled
in a similar manner to that employed for a similar purpose in what is known as the
"Shaftesbury lamp.
And in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed, aided by the accompanying drawings, more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a vertical section, Figure 2 a plan, and Figure 3 an elevation
of a lamp provided with extinguishing apparatus constructed according to the
invention. Figures 4 and 5 are two elevations drawn at right angles to each other,
and Figure 6 is an elevation partly in section showing the burner and parts connected
therewith full size, and Figure 7 is a cross section. Figure 8 is a plan and Figure 9
is an elevation of one half of the extinguisher full size. In Figures 1, 2, 4 and 5 the
extinguisher is represented open, whilst in Figures 3 and 6 it is represented closed
over the top of the wick tube or burner.
a is the lamp reservoir carried by a pillar or stand b, and c is the burner or wick
tube. The extinguisher is formed in two parts d. d, which, when in the position
required to extinguish the flame, fit together and form a complete cap extending
entirely over the top of the circular burner or wick tube c, and extending a short
distance down and around the same.

page_text: These two parts d. d. are provided with short dependent levers d¹ d', (one at each
side) formed at such reverse inclines or curves as to enable them to cross each
other and to be pin jointed in pairs at d² to the exterior of the burner or wick
tube c; the lower ends of these dependent lovers d¹ d'are connected by links d³ d³
to a moveable tube or ring d, which is connected, by a screw d³, to, and actuated
by, a rod de, which, as shown in the drawing, may be acted upon by a spring d',
or it may be acted upon by a weight, as in the "Shaftesbury" lamp. This rod dis
conducted through a tube e fixed in the bottom of the lamp reservoir a and
extending above the level of the oil therein.
The burner or wick tube c is connected to the lamp reservoir a in the following
manner. At the top of the reservoir a is a rim a¹, over which is turned the edge or
rim of a nut in such manner that, although the nut can be rotated on the
rim a', it cannot rise or fall in relation thereto. On the lower end of the burner or
wick tube c is a screw c' which fits the threads of the nut f. Thus, by turning the
nut in one or the other direction, the burner or wick tube c can be fixed to,
or disconnected from, the reservoir a, and, by removing the screw d connecting
the rod d with the ring or tube d, the burner can be completely removed from the
lamp, to enable a fresh wick to be placed therein.
If desired, the extinguishing apparatus herein described may be operated by hand
by means of the ordinary short lever or other means, or any suitable autoinatic
device may he employed for that purpose.
I would here remark that the other arrangements described in my provisional
specification do not possess such an amount of utility as to render it advisable
to further describe the same; I therefore desire to disclaim, and I do hereby disclaim,
such arrangements.
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
In extinguishing apparatus for circular or Argand burners of oil lamps, the
peculiar construction and arrangement of parts as herein shown and described.
Dated this 8th day of September 1888.
