Improvements in Gas Lighting Appliances.
I, WILLIAM EDWARDS, of 38 Witton Lane, Aston, in the County of Warwick,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to appliances for lighting gas jets or burners.
The object of my invention is to construct a gas lighting appliance to be used
with ordinary tapers or candles, and which, whilst it will readily light or ignite a
current of gas issuing from a jet or burner, yet will not light or ignite any
substance other than gas which may accidentally come into contact with it. In this
manner my improved gas lighter may be employed with safety in factories,
warehouses, and dwelling houses, aud in other places where the employment of the
ordinary and general methods of gas lighting is attended with the risk and danger
of fire.
In carrying my invention into effect, I employ a wax or other taper carried in a
tube or casing, such tube or casing being provided with a sliding rest or support
which can be elevated or raised as the taper burns down. At the upper end of the
tube or taper casing I fix a chamber within which the end of the taper burns.
The body of the chamber is formed of gauze, netting, or perforated plate of brass
or other suitable material, and to assist in the admission of air necessary for the
support of combustion of the taper, and to carry off the gaseous products formed by
combustion, I sometimes perforate the solid metal or other material forming the
base and the cap of the chamber. To allow of the more ready ignition of the gas
jet, I sometimes perforate or form enlarged apertures in the gauze, or netting,
through which the flame in the interior of the chamber can pass to and ignite
the gas around its exterior surface.
The combustion chamber is fixed to the tube or taper casing by means of a
hinged joint. When it is required to light or ignite the taper, the combustion
chamber is turned back on its hinge thus allowing the end of the taper to be
lighted or ignited by a burning match or other means. The chamber is then
closed and secured by a spring clip or other suitable fastening or securing device.
Instead of hinging the chamber to the tube or taper casing as hereinbefore
described, I sometimes make a detachable chamber which can be removed when
required, to allow of the lighting of the taper. To prevent the loss or mislaying
of the chamber when so removed I connect it by a chain or other flexible
connection to the taper casing.
I make the tube or casing of any required dimensions, to suit any desired size or
length of taper. Instead of a long and thin taper I sometimes employ a candle of
ordinary dimensions, making the tube or casing of the required size and strength to
receive the same, and providing a sliding rest or support for adjusting the burning
end of the candle within the combustion chamber.
In the use of my improved gas lighter, after the taper or candle has been ignited
in the combustion chamber as herein before described, the chamber end of the gas
lighter is placed in close proximity to the issuing current of gas from the burner or
jet that is to be lighted. The issuing gas will then enter the chamber and the
flame from within will communicate with and ignite the gas around the exterior of
the combustion chamber. As the taper or candle burns away at its lighted end it.
is forced upwards by the sliding rest or support, and when completely burnt away
a fresh taper or candle can be readily placed in the tube or casing as hereinbefore
described.

Improvements in Gas Lighting Appliances.
I, WILLIAM EDWARDS, of 38 Witton Lane, Aston, in the County of Warwick,
Engineer, 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 appliances for lighting gas jets or burners. The object
of my invention is to construct a gas lighting appliance to be used with ordinary
tapers or candles, and which, while it will readily ignite a current of gas issuing
from a jet or burner, yet will not light or ignite any substance other than gas
which may accidentally come into contact with it. Thus my improved gas lighter
may be employed with safety in factories, warehouses, dwelling houses, and in
other places where the employment of the ordinary and general methods of gas
lighting is attended with the risk and danger of fire.
I append hereunto one sheet of explanatory drawings to be hereinafter referred
to, and in which
Figures 1 and 2 represent front and side elevations respectively of one form of
my gas lighter, while
Figure 3 represents a modified form of combustion chamber.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect, I employ a wax or other taper, carried in a
tube or casing A, such tube or casing being provided with a sliding rest or
support B which can be elevated or raised as the taper burns down.
At the upper
end of the tube or casing A I fix a chamber 'C within which the end of the taper
burns. The body of the chamber I preferably form of perforated metal or of
wire gauze or netting, as shown in Figures 2 and 3, constructed from brass or other
suitable material. To assist in the admission of air necessary for the support of
combustion of the taper, and to carry off the gaseous products formed by combustion,
I perforate the solid metal or other material forming the lower & solid plate
portion of the chamber, the tube cap D and the chamber cap E, as illustrated in
Figures 1 and 2.
I preferably attach the combustion chamber or protecting hood C to the tube A
by means of a hinged joint such as F connecting the lower and solid plate portion
of the chamber to the tube cap D, which is soldered, brazed or otherwise secured
to the tube, and I fasten or secure the same by a catch, latch, or spring clip such
as G. To light or ignite the taper, the catch or latch G is released and the
chamber or hood C turned back on the hinge F, thus permitting of access to the
end of the taper and allowing it to be lighted or ignited by a burning match or
other means. The chamber or hood is then closed and fastened by the spring clip,
catch, or latch.
Instead of hinging the chamber or hood to the tube cap D on the tube or taper
casing A, as herein before described, I sometimes make a detachable chamber or
hood fitting into or over the base D and which can be entirely removed when
required. To prevent the loss or mislaying of the chamber when so removed, I
attach it by a chain or other flexible connection to the cap D or to the tube or
taper casing A.
I make the tube or casing A of any required dimensions to suit any desired size
or length of taper. Instead of a long and thin taper, I sometimes employ a candle
of ordinary dimensions, making the tube or casing of the required size and strength
to receive the same, and providing a sliding rest or support for adjusting the
burning end of the candle within a suitable combustion chamber or protecting hood
in the manner hereinbefore described.
In the use of my improved gas lighter, after the end of the taper or candle in
the combustion chamber has been ignited, the gas lighter is placed in close

page_text: proximity to the current of gas issuing from the burner or jet that is to be ignited
or lighted. The issuing gas will then enter the chamber or protecting hood and
the flame from within will communicate with and ignite the gas at the exterior of
the combustion chamber or hood.immediately over the jet or burner. As the taper
or candle burns away at its lighted end, it is forced upwards by the sliding rest
or support, and when completely burnt away a fresh taper or candle can be readily
placed in the tube or casing A as hereinbefore described.
Figure 3 illustrates a modified arrangement of combustion chamber or protecting
hood C' which I sometimes employ, having the wire gauze or netting made into
a conical form or shape. I also employ other modified shapes and patterns of the
various parts of my gas lighter without departing from the essential features of
my invention. To allow of the more ready ignition of the gas jet, I sometimes
perforate or form enlarged apertures in the gauze or netting of the combustion
chamber or hood through which the flame in the interior of the chamber can more
readily pass to and ignite the gas at the exterior. I preferably finish the end of
the tube A by soldering or otherwise securing within or to it a ring piece
such as H.
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. In gas lighting appliances, the combination of a tube or casing for containing
a taper or candle, with a sliding rest or support for elevating such taper or candle,
and a protecting hood or combustion chamber substantially as hereinbefore described
and as illustrated in the accompanying drawings.
2. The construction of an apparatus or appliance for use in lighting gas, having
a protecting hood or combustion chamber of gauze or like perforated material for
enclosing a burning taper or candle, such hood or chamber being hinged or
independently attached to the candle or taper tube or holder, substantially as and
for the purposes hereinbefore described, and as illustrated in the accompanying
drawings.
