"IMPROVEMENTS
IN EXTINGUISHING APPARATUS FOR LAMPS." (A communication from abroad by
Hugo Schneider, of Leipzig, Saxony.)
This Invention relates to improved arrangements of apparatus for extinguishing
the flame or light of hydro-carbon lamps, the objects being to simplify and
strengthen the construction of the extinguishing apparatus, and to enable it to bo
more readily removed from the lamp than those hitherto used to allow of the
charred portion of the wick being removed and of the lamp being cleaned.
As at present constructed these kinds of extinguishers have been made with
separate sliders for each wick tube, independent sliders being united by a con-
necting piece for duplex burners, each slider being fitted with an outer flap or
extinguishing piece actuated or closed when in proper elevation and position by a
spring, the sliders being raised and lowered by a rack and pinion, as described in
the Specification of certain Letters Patent, No. 686/", granted to Joseph Cole,
dated February 20, 1877; or, as just described, minus the springs and the rack
and pinion, fixed parts of the burners being used in lieu of the former in combination
with projecting parts of the hinged flaps for closing them, and a lever being used
in lieu of the latter for raising and lowering the duplicate sliders, as described in
the Specification of certain Letters Patent, No. 3155/7s, granted to David Pitcairn
Wright, dated August 9, 1878; or, as firstly described (but triplex), each slider
baving double flaps meeting centrally, and being actuated by double springs, the
raising and lowering of the triplex arrangement being effected by a lever, as in the
next preceding method, as described in the Specification of certain Letters Patent,
No. 386/ granted to Herbert Edwin Willis and John Pitt Bayly, dated
January 30, 1879; or, as described in the next preceding method (but duplex),

page_text: the flaps or lips of each slider being actuated by cams and also by springs, as
described in the Specification of certain Letters Patent, No. 588/", granted to John
Wakefield and William Edward Fisher, dated February 10), 1879.
The improved extinguisher is especially applicable to the duplex burner (though
it is also applicable to other burners), and it is designed to supersede the whole of
the extinguishers above referred to; and in order to attain the above mentioned
objects it is constructed with a single outer sliding case formed of one piece and
encircling both wick-tubes, and is fitted with two insido spring flaps (one to cach
wick-tube) forined of one piece of metal with projecting parts engaging in guide
slots in the surrounding case; or, according to another modification, with two
separate inner hinged flaps (one to each wick-tube), actuated by a single spring.
The inventor is thus enabled to considerably reduce the number of parts
required to produce the extinguisher, but two being absolutely necessary in the
first modification for a duplex-extinguisher, and this is principally owing to
having inner instead of outer flaps, and producing both flaps in one piece of metal,
which being suitably shaped has the necessary resiliency to produce the self-closing
of the flaps, thus dispensing with the springs, cams, and other means hitherto used
for effecting this purpose, and but four being necessary in the second modification,
namely, the single surrounding case, and the two inner flaps worked by one spring.
The raising and lowering of the improved extinguisher may be effected by a
lever or by any other suitable means.

CARL QUITMANN, of Jewin Crescent, in the City of London. "IMPROVEMENTS IN
EXTINGUISHING APPARATUS FOR LAMPS." (A communication from abroad by
Hugo Schneider, of Leipzig, Saxony.)
This Invention relates to improved arrangements of apparatus for extinguishing
the flame or light of hydro-carbon lamps, the objects of the improvements being
to simplify and strengthen the construction of the extinguishing apparatus, and
to enable it to be more readily removed from the lamp than the extinguishers
hitherto used to allow of the charred portion of the wick being removed and of
the lamp being cleaned.
As at present constructed these kinds of extinguishers have been made with
separato sliders (or sliding cases) for each wick tube, independent sliders being
united by a connecting pieco for duplex-burners, cach slider being fitted with an
outer flap or extinguishing piece actuated or closed when in proper elevation and
position by a spring, the sliders being raised and lowered by a rack and pinion, as
described in tho Specification of certain Letters Patent, No. 686, granted to
Joseph Cole, and dated February 20, 1877; or, as just described, but minus tho
springs and the rack and pinion, fixed parts of the burners being used in lieu of
the former in combination with projecting parts of the hinged flap for closing them,
and a lever boing used in lieu of the latter for raising and lowering the duplicato
sliders, as described in the Specification of certain Letters Patent, No. 3155,
granted to David Pitcairn Wright, and dated August 9, 1878; or, as firstly
described (but triplex), each slider having double flaps mecting contrally, and
being actuated by double springs, the raising and lowering of the triplex arrange-
ment being effected by a lever, as in the next preceding method, as described in
the Specification of certain Letters Patent, No. 386, granted to Herbert Edwin
Willis and John Pitt Bayley, and dated January 30, 1879; or, as described in the
next preceding method (but duplex), the flaps or lips of each slider being actuated
by cams and also by springs, as described in the Specification of certain Letters
Patent, No. 588", granted to John Wakefield and William Edward Fisher, and
dated February 10, 1879; or singly (as adapted to one round wick tube) with one
spring flap, being raised or lowered by a finger piece, as described in the Specifi-
cation of certain Letters Patent, No. 3904, granted to William Burd Woolley, and
dated September 29, 1879.
The improved extinguisher is especially applicable to the duplex burner (though
it is also applicable to the triplex or other multiplex burners), and it is designed to
supersede the whole of the extinguishers above referred to.
The Invention is illustrated on the annexed Drawings as adapted to a duplex
burner in Figs 1 to 11, and as adapted to a triplex burner in Figures 12 and 13.
In order to attain the above mentioned objects the improved extinguishing
apparatus is constructed with a single outer sliding case 1, which may be stamped
from or otherwise formed of one piece of metal soldered at its ends, see Figures 1 to 9
and 12, whether it be for a duplex, triplex, or other multiplex burner, the case being
formed of metal, and as shown in Figure 5, and encircling both (if it be for a duplex
burner, see Figures 1 to 4 and 6 to 9) or all (if it be for a triplex, see Figure 12
or other multiplex burner) the wick tubes 2, and is fitted with two (for a duplex),
or three or more (for a triplex or other multiplex burner) inside spring flaps 3
(one to cach wick tube), the spring flaps being formed of one piece of metal, sce
Figures 1 to 4, 10, and 13, with projecting parts 4 engaging in guide slots 5 in tho
surrounding case 1, or being otherwise equivalently guided; or according to the
modification illustrated in Figures 6 to 9 and 11 (Figure 5 being also common to this

page_text: modification) with two (for a duplex) or three or more (for a triplex or other
multiplex burner) separate inner hinged flaps 3* (one to each wick-tube) actuated
by a single spring 3**.
It has not been deemed necessary to illustrate every modification of which the
principle of this Invention is susceptible, as the main features of the Invention are
clearly hereinbefore set forth, together with a complete description of various
methods of carrying the same into practical effect; and following such instruction,
in conjunction with the annexed Drawings, any competent workman having the
necessary and usual materials could, without experiment or delay, at once be able
to make therefrom an extinguisher either for a duplex, triplex, or other multiplex
burner or lamp, to which the Invention could be applied. The main features are,
a single case surrounding both or all the wick tubes, and also the use in com-
bination therewith of inner spring flaps formed of one piece of metal, or of separate
inner hinged flaps, actuated preferably by a single spring, either circular or with
the requisite number of bearing arms or points.
The inventor is thus enabled to considerably reduce the number of parts
required to produce an extinguishing apparatus for any given multiplex burner or
lamp (he does not claim its application to single wick lamps), but two being
absolutely necessary in the first modification, and this is principally owing to having
a single surrounding case and inner instead of outer extinguishing flaps, and forming
both or all the flaps in one piece of metal, which being suitably shaped or bent, as
illustrated on the annexed Drawings, has the necessary resiliency to produce the
self-closing of the flaps, and thus dispensing with the springs, cams, and other
means hitherto used for effecting this purpose, and but four being necessary in the
second modification when for a duplex burner, namely, the single surrounding case
and the two inner flaps worked by one spring.
The raising and lowering of the improved extinguisher may be effected by a
lever or by any other usual or suitable means, this forming no part of the present
Invention.
Having now described the nature and object of the said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that I claim as the Invention communicated
to me by the said Hugo Schneider,—
The manufacture of extinguishing apparatus for duplex, triplex, or other multi-
plex burners, according to the principle hereinbefore described and illustrated on
the accompanying Drawings, such principle consisting in the application of the
following peculiar features:-The use of a single case or slider surrounding both or
all the wick tubes, and the use in combination with such a case of connected inner
spring flaps (one to each wick tube) formed of one piece of metal, or of separate
inner hinged flaps (one to each wick tube), actuated preferably by a single spring
having the requisite number of bearing points.
In witness whereof, I, the said Carl Quitmann, have hereunto set my
hand and seal, this Twenty-second day of September, in the year of our
Lord One thousand eight hundred and eighty.
CARL QUITSLANN. (LS.)
