Improvements in or connected with Incandescent Gas Burners.
I, GEORGE FREDERICK SANDERS, of the Hockley Street Works, Hockley Street,
City of Birmingham, in the County of Warwick, Manufacturer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in or connected with incandescent gas
burners, for protecting the same from draught and has for its object to provide
a simple and efficient means whereby the breakage of the glass or chimney, and
injury to the mantle is prevented. In ordinary incandescent gas burners the
glass or chimney is constantly breaking such breakage being caused by a current
of cold air passing up the said chimney or globe after the gas has been extin-
guished. When the mantle which constitutes an important part of the burner
becomes defective which is frequently caused by attempting to light spills and
the like therefrom, the glass or chimney becomes disannealed, hence the breakage
caused by the cold air passing up the chimney and especially when the burner is
exposed to strong draughts. By my invention these difficulties are overcome by
checking the cold air from passing up the chimney. In carrying my invention
into effect I provide a metal blank which I shape into an ornamental cup shaped
gallery arranged to carry the globe glass or chimney and having a closed bottom
so as to exclude the air from passing up the chimney. I connect the device
to the gas burner by piercing a hole in the centre and clipping the edges thereof
between the two flanges of the connecting screw pipe a little distance below the
gas tap which is enclosed within the globe or chimney. In order to enable the
gas being turned on or off without removing the globe or chimney I attach the
following arrangement to the gas tap. I cut a blank of sheet metal of suitable
shape and pierce the same with two rectilineal slots one at right angles to the
other, the vertical slot fits over the neck of the plug of the tap and the hori-
zontal oue is connected to the end of the lever of the plug by a
which forms a slide within the slot, thus an upward or downward movement
screw pin
causes the tap to be turned on or off which is effected by continuing the end of
the device through the bottom of the gallery, and terminating the same into a
loop. My invention may be applied to a gas globe by closing up the bottom
of the globe holder or by fitting therein a cup similar to the one before described,
the arrangement for operating the tap being the same as herein before described.
Dated this 22nd day of June 1899.

page_text: Improvements in or connected with Incandescent Gas Burners.
I, GEORGE FREDERICK SANDERS, of the Hockley Street Works, Hockley Street,
City of Birmingham, in the County of Warwick, Manufacturer, 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 the improvements hereinafter described in or con-
nected with incandescent gas burners for protecting the same from draught and
has for its object to provide a simple and efficient means whereby the breakage
of the glass or chimney and injury to the mantle is prevented. In ordinary
incandescent gas burners the glass or chimney is constantly breaking causing
injury to the mantle such breakage being caused by a current of cold air passing
- up the said mantle chimney or globe when the gas is burning.
When the mantle which constitutes an important part of the burner, becomes
defective which is frequently caused by attempting to light spilis and the like
therefrom, the glass or chimney becomes disannealed, hence the breakage caused
by the cold air passing up the chimney especially when the burner is exposed
to strong draughts. By my invention these difficulties are overcome by checking
the cold air from passing up the chimney and mantle.
In carrying my invention into effect I provide a metal blank which I shape
into an ornamental cup shaped gallery, arranged to carry the globe glass.or
chimney and having a closed bottom so as to exclude the air from passing up
the chimney. I connect the device to the gas burner by piercing a hole in the
centre and clipping the edges of the device between the two flanges of the
connecting screw pipe used with these burners a little distance below the gas
tap, which is enclosed within the globe or chimney.
In order to enable the gas being turned on or off without removing the globe
or chimney, I attach the following arrangement to the gas tap. I cut a blank
of sheet metal of suitable shape and pierce the same with two rectilineal slots,
one at right angles to the other: the vertical slot fits over the neck of the
plug of the tap, and the horizontal one is connected to the end of the lever of
the plug by a screw pin which forms a slide within the slot. Thus an upward
or downward movement causes the tap to be turned on or off which motion is
¡ effected by continuing the end of the device through. the bottom of the gallery.
and terminating the same into a loop. In cases where no by pass is used I may
dispense with the arrangement as the gas may be lit from the top of the
chimney. My invention may be applied to a gas globe by the closing up of the
bottom of the globe holder, or by fitting therein a cup similar to the one before
described the arrangement for working the tap being the same as herein before
described. In order that my invention may be more clearly understood, I will
describe it by reference to the accompanying drawings, the same.letters of
reference indicating similar parts throughout.
Figures 1 and 2 show a front and side elevation, and Figure 3 a plan of my
invention. Figure 4 is a vertical section, and Figures 5 and 6 are detail views
of the same. Figures 7, 8 and 9 show a modification of my invention.
A represents an ordinary incandescent burner, B the chimney and B the globe.
C is a cup shaped gallery made from a metal blank to carry the globe B. D,
Figure 6 is a metal plate arranged to fit the bottom of the gallery and to
restrict the passage of cold air through the holes d, d, to the burner.
In Figure 5 the plate is removed showing, more clearly the position of the
holes.

page_text: The gallery C is attached to the burner A by the screw sockets E and F
which clip the edge of the hole G.
The gas is turned on or off without removing the globe B2 by means of the
device H which is connected to the gas tap, the pin I sliding in the slot J.
The slot Kembracing the neck of the plug of the tap constitutes a slide, the
tail L passing through the slot M, Figures 5 and 6; is retained in any position
by the spring N. The tail L terminates in the loop enabling the gas being
turned on or off expeditiously.
The modification shown at Figures 7, 8 and 9 show the manner in which my
said invention may be applied to incandescent gas pendants in which the globe
holder G is provided with a closed bottom for preventing the cold air passing
to the mantle, the arrangement of parts being the same as in the aforesaid
arrangement.
The globe B is held in position on the holder C by the automatic clipping
device which is shown at Figure 9 with the clips extended, that is to say in
the act of clipping the globe.
At Figure 8 the clips are shown withdrawn from the grip of the globe, thus
releasing the same.
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:
1. The improvements in connection with incandescent gas burners, whereby
the cold air is prevented from passing up the chimney or globe, by closing up
the bottom of the gallery or globe holder substantially as described and illus-
trated.
2. The improvements in connection with incandescent gas burners, whereby
the burner mantle and gas tap are enclosed within the globe and the cold air
prevented from reaching the same substantially as and for the purpose set forth.
3. The arrangement whereby the plug of the tap may be turned on or off
without removing the globe or shade therefrom substantially as in the manner
described and illustrated in the accompanying drawings.
4. The combination with an incandescent gas burner of the gallery or globe
holder Chaving a closed up bottom, the plate ]) for preventing the cold air
reaching the mantle or chimney as described and illustrated.
5. The combination with an incandescent gas burner as claimed above the
arrangement of turning on or off the gas by means of the device H without
removing the globe or shade substantially as described and illustrated.
Dated this 29th day of January 1900.
