I, BARUCH CARS, of Venus Lamp Works, 124-130, Tabernacle Street, Finsbury,
in the County of Middlesex, Lamp Manufacturer, do hereby declare the nature of
this invention to be as follows:-
The invention relates to improvements in or connected with lamp extinguishers
for round wick or Argand burners and consists in the peculiar combination of
parts hereinafter described.
In carrying the invention into effect a cylindrical or tubular extinguisher is
employed which surrounds the wick tube and is vertically movable so that it may
normally lie beneath the top edge of the wick tube or be raised against the
underside of the button or Hame spreader when it is desired to extinguish the
flame of the lamp.
In order to raise and lower the extinguishing tube at the times desired said
tube is provided with a depending rack bar rivetted thereto and consisting of a
strip of metal perforated at suitable intervals to constitute a rack and in con-
nection with this rack is employed a pinion located within the collar of the burner
and this pinion is fixed upon the inner end of a tubular shaft projecting hori-
zontally from the collar of the burner and having fixed upon the outer end thereof
a double grooved pulley.
Each groove of the pulley is provided with a length of cord or the like which
passes wholly or partly around the same and at its end is fixed with the pulley said
cords being wound upon the pulley in opposite directions and at their depending
ends provided with rings buttons or the like by means of which the cords may
be manipulated.
The tubular shaft of the pulley passes through a tubular guide projecting hori-
zontally from the burner collar and the spindle of the wick winder passes through
the tubular shaft of the pulley and the outer end of the tubular guide is fur-
nished with a forked guard embracing the periphery of the double pulley at
opposite points so as to prevent the cords running out of the grooves.
By this arrangement of parts in order to raise the cylindrical extinguisher
against the underside of the button or spreader and thus extinguish the flame of
the lamp it is merely necessary to exert a pull upon one of the cords
whilst a similar pull upon the other cord will lower the same to
its normal position and in order that the cords may be easily identified
they are formed of differently coloured silk or other material or are fitted with
differently shaped terminal rings or buttons.
By the means herein before described a simple and inexpensive extinguishing
device is obtained which is easy to manipulate and by reason of the heat non-
conducting character of the cords may be manipulated without discomfort.

I, BARUCH CARS, of Venus Lamp Works, 124-130, Tabernacle Street, Finsbury,
in the County of Middlesex, Lamp Manufacturer, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
The invention relates to improvements in or connected with lamp extinguishers
for round wick or Argand burners and consists in the peculiar combination of
parts hereinafter described.
In carrying the invention into effect a cylindrical or tubular extinguisher is
employed which surrounds the wick tube and is vertically movable so that it may
normally lie beneath the top edge of the wick tube or be raised against the
underside of the button or flame spreader when it is desired to extinguish the
flame of the lamp.
In order to raise and lower the extinguishing tube at the times desired said
tube is provided with a depending rack bar rivetted thereto and consisting of a
strip of metal perforated at suitable intervals to constitute a rack and in con-
nection with this rack is employed a pinion located within the collar of the burner
and this pinion is fixed upon the inner end of a tubular shaft projecting hori-
zontally from the collar of the burner and having fixed upon the outer end thereof
a double grooved pulley.
Each groove of the pulley is provided with a length of cord or the like which
passes wholly or partly around the same and at its end is fixed with the pulley said
cords being wound upon the pulley in opposite directions and at their depending
ends provided with rings buttons or the like by means of which the cords may
be manipulated.
The tubular shaft of the pulley passes through a tubular guide projecting hori-
zontally from the burner collar and the spindle of the wick winder passes through
the tubular shaft of the pulley and the outer end of the tubular guide is fur-
nished with a forked guard embracing the periphery of the double pulley at
opposite points so as to prevent the cords running out of the grooves.
By this arrangement of parts in order to raise the cylindrical extinguisher
against the underside of the button or spreader and thus extinguish the flame of
the lamp it is merely necessary to exert a pull upon one of the cords
whilst a similar pull upon the other cord will lower the same to
its normal position and in order that the cords may be easily identified
they are formed of differently coloured silk or other material or are fitted with
differently shaped terminal rings or buttons.
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, is an elevation of a lamp having the present invention applied thereto
part of the burner being broken away in order to expose the extinguisher which
is in its normal or depressed position.
Figure 2 is an elevation taken at right angles to Figure 1 of the lamp but
with the chimney holder and gallery removed and showing the extinguisher in its
raised position.
Figure 3 is a sectional elevation the section being taken on the line 1-1 of
Figure 4 representing the extinguisher and connected parts separately.

page_text: Figure 4 is a horizontal section taken on the line 22 or Figure, and rigure
is a detail view of parts.
In the several figures in which like parts are indicated by similar letters of
reference Figures 3 and 4 are drawn to an increased scale with respect to Figures 1
and 2 whilst Figure 5 is drawn to a further increased scale.
a represents the oil reservoir or container a¹ represents the neck thereof and b
represents the collar of the burner which is furnished with the usual thread b
to screw into a corresponding thread in the collar a¹.
c represents the extinguisher which is cylindrical or tubular and surrounds the
wick tube and this extinguisher is vertically movable as hereinafter described
so that it may normally lie beneath the top edge of the wick tube 2 as shown at
Figures 1 and 3 or be raised against the underside of the button or flame
spreader e as indicated at Figure 2 when it is desired to extinguish the flame of
the lamp.
In order to raise and lower the extinguishing tube c at the times desired said
tube is provided with a depending rack bar e rivetted thereto and consisting of a
strip of metal at suitable intervals formed with perforations to constitute a rack
and in connection with this rack is employed a pinion & located within the
collar b of the burner and this pinion is fixed upon the inner end of a tubular
shaft projecting horizontally from the collar of the burner and having fixed
upon the outer end thereof a double grooved pulley d.
Each groove of the pulley d is provided with a length of cord or the like d. dr
which passes wholly or partly around the same and at its end is fixed with the
pulley by passing through a lateral hole therein and being formed with a knot d*
or * as the case may be upon the extreme end thereof and said cords d³d are
wound upon the pulley d in opposite directions and at their depending ends are
provided with rings buttons or the like d d by means of which the cords
may be manipulated.
d
The tubular shaft d' of the pulley d passes through a tubular guide f projecting
horizontally from the collar of the burner, and the spindle g of the wick
winder passes through the tubular shaft d of the pulley d and at its inner end
is furnished with a pinion g² which engages the rack h¹ of the wick carrier h.
In order to prevent the cords accidentally running out of the grooves of
the pulley a forked guard f is provided which is carried by the tubular guide f
and embraces the periphery of the double pulley at opposite points and thus
keeps the cords 'dd under control.
By this arrangement of parts in order to raise the cylindrical extinguisher c
against the underside of the button or flame spreader e as indicated' at Figure 2
and thus extinguish the flame of the lamp it is merely necessary to exert a pull
upon the cord d by the ring do when the required motion will be communicated
through the tubular shaft & pinion and rack bar c¹ to the extinguisher c
whilst a similar pull upon the other ring of the cord will lower the extin-
guisher to its normal position as indicated at Figures 1 and 3.
The cords ³d are formed of differently coloured silk or other material or they
may be formed with differently shaped terminal rings or buttons in order that
they may be easily identified.
By the means hereinbefore described a simple and inexpensive extinguishing
device is obtained which is easy to operate, and by reason of the heat non-con-
ducting character of the cords 3d may be manipulated without discomfort.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In an oil lamp the combination of a cylindrical extinguisher surrounding the
wick tube and adapted to be raised against the flame spreader at the times desired,
a tubular guide extending horizontally from the burner collar, a shaft working in
said guide and at one end provided with means for actuating the extinguisher
