Improvements in or relating to Regenerative Gas Lamps.
I, EDWIN CHARLES RIBBANS of 117 Fore Street, Ipswich Tin plate worker doi
hereby declare the nature of this invention to be as follows:-
1.
This Invention has for its object improvements in those regenerative lamps provided
with inverted gas-burners, and in order that the nature of my Invention may be
understood I will describe the same as applied to what is known as a Siemens
Regenerative Gas-lamp. It consists of an addition to the said Siemens lamp or
other form of said variety of lamp, whereby the lamp may be used out of doors,"
or in lobbies or other draughty places, the said addition preventing a downward
draught or current of air from having practically any effect upon the light given by
the said lamp.
Around the lower part of a Siemens lamp, which lower part is of a larger diameter
than the upper part or chimney; I place a cylindrical casing the upper part of which,
or that part at or about the level of the junction of the two diameters of the said
Siemens lamp, is coned or bent inwards. To the exterior of the cylindrical casing at
or near the bottom of its coned part is attached a circular plate, perforated at its
inner part, which plate forms part of an annular bend or bulge. To this perforated
circular plate is attached the upper part of the framing for the lantern of the lamp,
which upper part is perforated. The surrounding air passos through the perforated
upper part of said framing and through the perforated circular plato and also through
perforations in the external part of the annular bend or buige into the interior of the
lamp constructed according to my Invention, and hereinafter called the entire lamp,
the air being guided or deflected by the cone on the cylindrical casing.
Air is admitted for combustion through perforations in the lower part of the lantern,
and that part of the air which is not used for combustion passes upwards between the
cylindrical casing and the Siemens lamp into the interior of the entire lamp, being,
guided or deflected by the cone on the cylindrical casing.
The lantern itself may be of any suitable shape or construction.
To the upper part of the aforesaid annular bend is attached a cylindrical.ring
perforated for the passage of air. To the upper part of this perforated ring is attached
a flanged cone, which cone surrounds the upper part of the chimney of the Siemens.
lamp. To the flange of this cone is fixed another cylindrical ring perforated for the
passage of air. The said flanged cone serves to guide or deflect the air passing through
the two perforated cylindrical rings aforesaid. The last mentioned perforated ring bas
fixed to its upper end a flanged cylinder, the flange of which may be bent downwards
and around the perforated ring to which it is attached. The upper part of the flanged
cylinder is perforated and is provided with a perforated flange to which perforated
flange is attached a solid cylindrical ring or guard, extending sufficiently downwards
to cover the said perforated upper part of the flanged cylinder. The solid cylindrical
ring or guard and the flanged cylinder are surrounded by an outer perforated
cylindrical guard. Above the flanged cylinder are arranged a number of superposed
rings, the spaces between which serve as exits for the air which has been drawn into
the lamp and for the products of combustion. These superposed rings are themselves
surrounded by a perforated cylindrical ring to the top of which ring is attached a solid
cone. Over the cone is placed a cap, and the space between the said cone and cap
forms the final outlet for the heated air and products of combustion. The perforated
cylindrical ring surrounding the aforesaid superposed rings serves to admit fresh air and
also permits of the escape of some of the heated air and products of combustion.
When a downward draught or current of air gets into the lamp it rushes down and
is guided or deflected outwards by the said cones and passes through the said

page_text: .
perforated cylindrical rings into the surrounding air, little or none of the downward
draught reaching the Siemens lamp itself, which enables it to give a steady light.
By the same arrangement of perforated cylindrical rings etc., a constant supply or
stream of fresh air passes into the interior of the entire lamp, which supply is guided
or deflected in the proper direction by the cones and keeps the said Siemens lamp
cool.
Some of the lower parts of the entire lawp may be polygonal to accord with the
shape of the lantern.
The Siemens lamp is supported in any suitable manner within the entire lamp, and
the various parts constituting the latter are fixed to one another in any suitable
manner.
In lobbies, or other covered places, 1 may dispense with the arrangement of some or
all of the parts in the lower portion of the entire lamp, and employ only the arrangement
of the parts in the upper portion of the same, which will be found to be all that is
needed in such cases.

COMPLETE SPECIFICATION.
Improvements in or relating to Regenerative Gas Lamps.
1, EDWIN CHARLES RIBBANS, of 117 Fore Street, Ipswich, Tin plate worker, 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 has for its object improvements in those regenerative lamps which are
provided with inverted gas-burners. And in order that my invention may be
thoroughly understood I will describe the same as applied to what is known as a
Siemens Regenerative Gas Lamp. It consists of an addition to the said Siemens lamp
or other form of said variety of lamp, whereby the lamp may be used out of doors, or
in lobbies or other draughty places, the said addition preventing a downward draught
or current of air from having practically any effect upon the light given by the said
lamp.
The accompanying drawing is a section showing my improvements applied to a
Siemens Regenerative Gas Lamp.
Around the lower part, a of a Siemens lamp, which lower part a is of a greater
diameter than the upper part or chimney a!, I place a cylindrical casing B the upper
part of which, or that part at or about the level of the junction of the two diameters
of the Siemens lamp, is conod or bent inwards. To the exterior of the cylindrical
casing B at or near the bottom of the coned part b, is attached a perforated plate C
which forms part of a bend or bulge D. The perforated plate and the bend or
bulge D may be of a hexagonal, circular or other shape to accord with that of the
lantern E. To the perforated plate Cis attached the upper part e of the framing of the
lantern E, which upper part is perforated. A bent or angular deflecting ring F may
be fixed to the upper part e of the framing of the lantern E and below the perforations
in the same and perforations in the outer part of the plate C. The air surrounding
the lamp passes, as shown by the arrows, through the perforated upper part e of the
lantern E and through the perforated plate and also, through perforations in the
external part of the bend or bulge D into the interior of the lamp constructed according.
to my invention, and hereinafter called the entire lamp, the air being guided or deflected
by the cone on the cylindrical casing B. A portion of the air which passes into the
upper part e of the framing of the lantern E is guided by the deflecting ring F and
passes downwards to supply the gas-burners of the Siemens lamp with the air necessary
for combustion. Or, I may dispense with the deflecting ring and perforate only the

page_text: inner part of the plate C. Part of the air necessary for combustion may also pass into
the lautern E by incans of perforations at eat other part of the same.
The lantern E may be of any suitable shape or construction.
To the upper part of the bend or bulge D is attached a cylindrical ring G perforated
for the passage of air. To the upper part of the perforated ring G is attached a
flanged cone H, which surrounds the upper part of the chimney a' of the Siemens
lamp. To the flange h of this cone is fixed another cylindrical ring I perforated for
the passage of air. The flanged cone H serves to guide or deflect the air passing
through the perforated cylindrical rings G and I. The perforated ring I has fixed
to its upper end a flanged cylinder J, the flange of which may be bent down-
wards and around the perforated ring I. The upper part of the flanged cylinder J
is perforated and is provided with a perforated Hange, to which flange j² is
attached a solid cylindrical ring or guard K, extending sufficiently downwards to
cover the said perforated upper part of the flanged cylinder J. The solid
cylindrical ring or guard K and the flanged cylinder J are surrounded by an
outer perforated or slotted cylindrical guard L. I prefer to fix at right angles to
the flanged cylinder J a solid ring or annular projection J, which serves to
additionally promote the passage of air through the upper perforated parts of
the flanged cylinder J. Above the flanged cylinder Jare arranged a number of
superposed rings M, the spaces between which serve as exits for the air which
has been drawn into the entire lamp and for the products of combustion. The
Euperposed rings Mare themselves surrounded by a perforated cylindrical ring N, to the
top of which ring N is attached a solid cone O. The solid cone U may, if desired, be
joined to a solid cylindrical ring P. Over the cone 0, or over the cylindrical
ring P, is placed a cap Q, and the space between the cone O and the cap or
between the cylindrical ring P and the cap Q serves as the final outlet for the
heated air and the products of combustion. The perforated ring N surrounding
the superposed rings M serves to admit fresh air and also permits of the escape
of some of the heated air and products of combustion.
When a downward draught or current of air gets into the upper part of the lamp
constructed in accordance with my invention it rushes down and is guided or deflected
outwards by the cones Hand and passes through the perforated cylindrical rings (
and & into the surrounding air, little or none of the downward draught reaching the
Siemens lamp itself, which enables it to give a steady light. Some of the downward
draught or current of air passes through the perforations in the bend or bulge D, the
plate Cand the upper parte of the lantern F, but the greater part passes, as afore-
said, through the perforated cylindrical rings 1 and G.
By the same arrangement of perforated cylindrical rings, etc., a constant supply or
stream of fresh air passes into the interior of the entire lamp, which supply is guided
or deflected in the proper direction by the cones and keeps the said Siemens lamp
cool.
The Siemens lamp is supported in any suitable manner within the entire lamp, and
the various parts constituting the latter are fixed to one another in any suitable
manner.
The gas for the burners of the Siemens lamp may be supplied by pipes placed at
each side of the entire lamp and passing through the bend or bulge or other part of
the entire lamp, as shown by dotted lines in the drawing. Pipes which may be
ornamented in any suitable manner are fixed to the ends of the pipes passing through
the bend or bulge or other part of the entire lamp and form a bracket by means of
which it may be fixed in the desired position.
Although I have described my invention as being applied to a Siemens Regenerative
Gas Lamp it is also applicable to other varieties of regenerative gas lamps provided
with inverted gas-burners.
In lobbies, or other covered places, I may dispense with the arrangement of some or
all of the parts in the lower portion of the entire lamp, and employ only the arrange-
ment of the parts in the upper portion of the same, which will be found to be all that
is needed in such cases.

page_text: 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 :-
The application to a Siemens or other regenerative gas lamp provided with inverted
gas burners of the improvements described herein and illustrated by the accompanying
drawing.
