PROVISIONAL SPECIFICATION.
Improvements in Gas Lamps.
1 WALTER JOSEPH HIGGINSON of 12 Pelham Grove Liverpool in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
Lamps under my invention are of the class in which inverted ring burners within
a closed globe are used, in which the flame passes from the burner up a central
tube or chimney, and in which air to support combustion enters the globe through
passages surrounding a central chimney.
The object is to simplify and improve the construction of such lamps.
Lamps under my invention have the following novel features:-
First. An annular casting perforated at its lower end, and provided with an inlet
way at its upper end, and with one or more partition pieces all so disposed that
when a tube is driven through or around the said casting, an annular gas reservoir
and. a burner are formed. In some cases the tube also serves as a chimney.
Second. An annular deflector is suspended within the chimney, so that air in its
passage to the burner, flows between the said deflector and the walls of the
chimney.
Third. Passages are arranged so that air on its way to the burner first descends
between the deflector and a partition and then ascends until it reaches a space from
which there are descending passages leading to the interior and exterior of the
burner.
Fourth. In fitting the exterior ring of the lamp with upwardly extending springs
so disposed as to retain the globe in position yet allow of its easy, withdrawal.

Improvements in Gas Lamps.
IWALTER JOSEPH HIGGINSON of 12 Pelham Grove, Liverpool in the County
of Lancaster, 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:-
Lamps under my invention are of the class in which inverted ring burners within
a closed globe are used, in which the flame passes from the burner up a central
tube or chimney; and in which air to support combustion enters the globe through
passages surrounding a central chimney."
The object is to simplify and improve the construction of such lamps.

First. An annular casting perforated at its lower end and provided with an inlet
way at its upper end and with one or more partition pieces all so disposed that
when a tube is driven through or around the said casting, an annular gas reservoir
and a burner are formed. In some cases the tube also serves as a chimney.
Second. An annular deflector is suspended within the chimney so that air in its

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a vertical section of a lamp more particularly illustrative of the first,
second, and fourth parts of my invention a is an annular casting perforated at b
below to form the burner provided with an inlet way c at its upper end, and having
a partition piece d between the inlet way e and the perforations b, e, is a tube driven
around the annular casting so as to make tight joints at top and bottom. f is the
chimney which forms a continuation of the annular casting. Within the chimney
is suspended from a ring g, a deflector by means of lugs, projections, set screws,
or any usual or convenient agents, and air ways i are made through the chimney so
that air to support combustion may flow down to the burner between the chimney
or tube and the deflector. j is a globe held in position by means of upwardly
extending springs k secured to the tube e which here forms the exterior ring of the
lamp. The air in its passage down to the burner becomes heated, and the gas
flowing from the inlet way e to the perforations is obstructed by the partition
piece d so that the flow is more regular and uniform.
Fig. 2 is a vertical section and Fig. 3 is a cross-section of a lamp similar to that
described under Fig. 1, but having the tube e driven within instead of around the
annular casting a whilst the chimney f forms a continuation of, or may be made as
part of the said tube e. is the exterior ring of the lamp which carries the
springs k. In this modification, air to support combustion passes to the burner
through the space between the exterior ring and the annular casting as well as
between the deflector and the chimney or tube. The annular casting a is made with
a perforated flange m to ensure proper distribution of air to the exterior of the
burner. The deflector is here shown suspended by means of a set screw n and is
adjusted centrally by means of additional set screws o.
Fig. 4 is a vertical section of a lamp more particularly illustrative of the third
part of my invention, here partitions p-p are placed between the deflector hand
the burner, so that air to support combustion entering through openings in the
tube e first descends between the deflector and the partition p and then ascends
between the partitions p, p, until it reaches the space from which it descends to
the interior of the burner by the passage between the partition p', and the tube e,
and after passing through openings in the tube e descends by the passage
between the annular casting a and the exterior ring 1.
In all the views, like letters denote the same parts.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
First. In gas lamps the combination of an annular casting having gas inlet, and
burner perforations, with a tube driven through or around the said annulus and
nsual or suitable chimney, deflector, and globe.
Second. In gas lamps the combination of an annular casting having gas inlet and
burner perforations, and partition piece with a tube driven through or around the
said annulus, and the usual or suitable chimney, deflector and globe.
Third. Gas lamps having an annular burner and central chimney with deflector
suspended within the chimney and an air passage between the deflector and
chimney.
Fourth. Constructing gas lamps with descending and ascending ways for air
between a deflector and the external ring substantially as set forth.

page_text: Fifth. Gas lamps with upwardly extending springs for carrying the globe
substantially as set forth.
Sixth. Gas lamps constructed substantially as herein set forth.
