PROVISIONAL SPECIFICATION.
Improvements in and connected with Burners for Incandescent
Gas Lights.
I, ARTHUR ROSE, of 65, Douglas Road, Handsworth, in the County of Stafford,
Gas Burner Manufacturer, do hereby declare the nature of this Invention to be as
follows:-
This Invention consists of the herein described improvements in and connected
with burners for incandescent gas lights where the incandescent mantle is heated
by atmospheric gas from a Bunsen burner.
According to the first part of my Invention I make the gas burner proper of a
mixture of fire-clay, or other suitable plastic material as now used for gas burners,
moulded into a cylindrical shape open at the bottom and made with a ring of
holes at the top through which the gas issues. There is also a central circular
hole in the top to take the plug hereinafter described. Within the said burner
and underneath the ring of holes there is fitted a ring of wire gauze to prevent the
gas from flashing back. The said burner is made to fit in and upon a hollow
circular metal base piece which has holes in the top through which the gas passes
and at the bottom is screwed or otherwise fixed on to the top of the tube which
receives the atmospheric gas from the lower part of the Bunsen burner. The
said cylindrical part of the burner is fixed on to the base by means of a central
plug which is or may be made of gas burner material moulded to the proper form
and is provided with a tubular metal spigot at the bottom which screws into the
centre of the metal base so that the said cylindrical part of the burner is held
between the cap or head of the plug and the base. This plug is made with a small
central hole at the top to receive the stem which carries the mantle. At the side
of the said hole which carries the stem there is formed in the plug a small hole
through which ordinary gas passes to form the pilot light this gas coming from
the central tubular part of the plug which is connected by a pipe to the usual bye-
pass.
A gas burner made as above described in accordance with this Invention is much
more lasting in wear than are the burners usually made for incandescent gas lights.
According to the second part of this Invention I employ a cap on the top of the
glass or other chimney which surrounds the mantle this cap being made with holes
at the top or in the sides, or in the top and sides, said holes being of such a size
as to check the rapid rush of air through the chimney. By this means I find that
there is a considerable economy of gas effected as by checking the rapid draught of
air through the chimney the amount of gas consumed can be reduced without
impairing the light. The said cap is made of a mixture of fire-clay or other suitable
heat resisting material made to fit upon or within the top of the glass or tale or
other chimney. The openings in the cap may if desired be regulated by means of
017

page_text: a slide or disc which is made with holes corresponding with those in the cap
and
which can be turned so as to partly close the said holes to give the area desired.

Improvements in and connected with Burners for Incandescent
Gas Lights.
I, ARTHUR ROSE, of 65, Douglas Road, Handsworth, in the County of Stafford,
Gas Burner Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
This Invention consists of the herein described improvements in and connected
with burners for incandescent gas lights where the incandescent mantle is heated
by atmospheric gas from a Bunsen burner.
I will describe my Invention by referring to the accompanying drawings on
which Fig. 1 is a sectional elevation and Fig. 2 is a plan of an incandescent gas
light burner embodying my Invention; Fig. 3 shews the parts of my Invention
separately; Fig. 4 shews the usual lower Bunsen burner part of the burner but
which forms no part of my Invention; Fig. 5 is a plan of a modified form of a part
of my improved burner: Fig. 6 is a sectional elevation and a plan of a cap which
according to the second part of my said Invention I employ on the top of the
chimney which surrounds the mantle and incandescent gas burner; Fig. 7 is a
sectional elevation of a modified form of the said cap and Fig. 8 is an elevation and
plan of a further modified form of the said cap; Fig. 9 is a sectional elevation and
a plan of a further modification of the same; and Fig. 10 shews a further modifica-
tion of the said cap.
The same letters of reference indicate the same or corresponding parts in all the
Figures of the drawings.
According to the first part of my Invention (see Figs. 1, 2, 3, and 5) I make
the burner proper A of a mixture of fireclay or other suitable plastic material as
now used for burners moulded into a cylindrical shape as shewn open at the bottom
and made with a ring of holes a² at the top through which the gas issues. These
holes a² may be round (Fig. 3.) or oblong (Fig. 5) or of other shape. There is also
a central hole a at the top to take the plug B hereinafter described. Within the
burner A and underneath the ring of holes a² there is provided a ring of wire
gauze c to prevent the gas from flashing back. The burner A is made to fit in
and upon the circular sheet metal baso piece 1) which has holes in the top through
which the gas passes and at the bottom 2 is screwed on to the tube E which fits
on the tubular part f of the lower part of the Bunsen burner and receives the
atmospheric gas from the same. The base D is by preference made with a rebated
part d³ on which the cylindrical part A of the burner fits and where the part A
of the burner is fixed to the base D by means of the central plug B which is or
may be made of gas burner material moulded to the shape shewn in Figs. 1, 2 and 3
provided with a tubular metal spigot g fixed to its bottom end which screws into
the central hole d of the metal base D so that the cylindrical part A of the burner
is held between the cap or head b₁ of the plug B and the base D. This plug B is
made with a small central hole 2 at the top to receive the stem which carries the
mantle. At the side of the hole there is formed in the plug B a small hole 63
through which ordinary gas passes to form the pilot light this gas coming from the

page_text: chamber b in the central tubular part B of the plug which is connected to the usual
bye-pass by the usual small pipe which fits in the central hole g¹ in the spigot g
but is not shewn on my drawings. It will be understood that when the burner is
in use the gas rises up from the usual lower part F of the Bunsen burner the air
entering by the holes f¹ and the mixed air and gas pass out through the holes d¹
and up through the wire gauze c and issues out through the holes a² giving a round
flame to heat the mantle which is not shewn but it will be understood is carried
by the usual stem in the hole 62 and fits around the cylindrical part A of the burner.
A gas burner made as above described is much more lasting in wear than are
the burners as usually made for incandescent gas lights.
The plug B is made without the small hole 63 when there is no bye-pass.
According to the second part of this Invention (see Figs. 6, 7, 8 and 9) I employ
a cap H on the top of the glass or other chimney I which surround's the
mantle this cap being made with small holes h at the top (see Figs. 6, 7, 8 and 10)
or holes h at the sides (see Fig. 9) or in both the top and sides said holes being of
such a size as to check the rapid rush of air through the chimney I.
By this
means I find the gas is economized as by checking the rapid rush of air through
the chimney the amount of gas consumed can be reduced without impairing the
night.
The said cap H is made of a mixture of fire-clay or other suitable heat resisting
material such for instance as X metal and is made to fit upon the top of the
chimney I and either outside the same as in Figs. 6, 8, 9 and 10 or inside the same
as in Figs. 7.
The size of the openings h in the cap H may if desired be regulated by means
of a slide or disc such as J (Fig. 10) which is made with holes j corresponding with
the holes in the cap H and which can be turned so as to partly close the said
holes h to give the area desired.
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 an atmospheric gas burner for incandescent gas lights, the combination of
an upright pipe such as E through which the mixed air and gas pass to the burner,
the open bottomed cylindrical burner proper A fitting on the top of said pipe and
made with a ring of holes in the top for the passage of the mixed gas and air and
the plug B which secures the burner A to the top of the upright gas tube and has
a central hole to carry the stem which supports the incandescent mantle, all sub-
stantially as herein before described.
2. In combination with an incandescent gas light burner mantle and chimney
the employment of a perforated fire-clay or other non-inflammable cap H fitting on
or in the top of the said chimney to check the current of air therethrough, said cap
being constructed and arranged in any of the several ways substantially as herein-
before described and illustrated by Figs. 6, 7, 8, 9 and 10 of the accompanying
drawings.
