place of the central projection in the glass of the original lamp.

prevents a deposit being formed upon it.

lighting or other purpose by lowering the glass whilst it remains still supported by
the stem.

"IMPROVEMENTS
IN GAS BURNER APPARATUS "
This Invention relates to improvements on the gas burner apparatus described
in the Specification of a Patent granted to G. S. Grimston, one of the present
applicants on the 24th day of February 1882 N° 900.
The burner apparatus we now construct as follows. The gas is delivered in a
downward direction from the lower ends of a number of small vertical tubes
arranged in a circle as in the original burner.
A larger tube or cylinder surrounds this group of small tubes and projects
below them. At the centre of the same group a flat disc of metal or earthenware
capable of adjustment or preferably a conoidal deflector is suspended. A current
of heated air descends the large tube or cylinder and issues at the lower end of
the cylinder together with the gas.
The gas and air there meet the deflector and the direction of the current is
changed, becoming nearly horizontal and radiating outwards from the centre every
way. The gas being ignited forms a ring or sheet of flames. The general hori-
zontal direction of the flame is preserved by a flange upon the exterior of the
cylinder at its lower end.
The flange is made or covered with white porcelain or refractory material. Near
the outer edge of the flange the flame ceases. The products of combustion rise
around the edge of the flange to its upper side where they are more, or less confined
by a rim encircling the flange but of sufficiently large diameter to leave a free
annular passage upwards.
From the partially enclosed chamber above the flange the heated products are
able to ascend through a number of vertical tubes and they thereby enter a
casing in connection with a chimney. The gas pipe descends through the chimney
and terminates in a box within the casing above referred to.
The small gas
delivery tubes are inserted in to the bottom of this box.
The air to supply combustion enters laterally between the tubes by which the
products of combustion ascend and traverses wire gauze in contact with these tubes
and led around in a zig-zag course amongst them. Thus both the gas and air
become highly heated as they approach the place where combustion takes place.
The heated air together with the gas is drawn down to the flame through the
large centre tube or cylinder by the draft of the chimney.
The burner is enclosed in a glass lantern in one or more parts so arranged that

Above the metal disc there is a conoidal deflector, also of metal, which takes the
place of the central projection in the glass of the original lamp.

In order that our said Invention may be most fully understood and readily
carried into effect we will proceed to describe the Drawings hereunto annexed.

lower end of the cylinder d is capable of adjustment.
fis the chamber over the flange d¹. Sufficient space is left around the edges of
the flange d¹. for the highly heated products of combustion to enter the chamber f.
g. g. are numerous vertical tubes by which the products of combustion ascend and h
is the chimney which they enter and by which they escape. g'. g¹. is wire gauze
wound in and out amongst the tubes g. g. The air in entering passes through the
interstices of this gauze and so becomes highly heated. The gauze being in contact
with the tubes the heat passes to it freely by conduction.
ii. is a portion of the frame of the lantern. This frame may be of any form or
pattern and glass is fitted to it so that the entrance of air otherwise than by the
cylinder d. is prevented.
Figure 3 shows a vertical section of a burner and parts constructed according to
the latter part of our invention where the flame is allowed to descend vertically as in

metal ring supporting the glass. m is a telescopic stem by which the ring is
suspended. The stem consists of two tubes the lower can slide upon the upper
and when raised it can be linked by a bayonet catch. The catch engages on a
partial turn being given to the ring after the lamp has been closed.
n is the metal deflector, serving also as a valve admitting air within the glass
bowl, it can be regulated by a screw.
What we claim is:-
First. The cylinder d. with its collar or flange d. and the deflector e. directing
the flame substantially as described.
Second. The vertical tubes g. g. and wire gauze or recticulate metal g¹. g¹.
imparting heat to the air entering and passing to the flame substantially as
described.
Third. The bowl k with opening at the bottom the ring 1. the stem m and
deflector n. substantially as described.
Fourth. Our improved gas burner apparatus substantially as described.
In witness whereof I the said Anthony Spencer Bower have hereunto set my
band and seal this twentieth day of July in the year of our Lord One thousand
eight hundred and eighty three.
