Improvements relating to Petroleum and other Lamps.
I, EDWIN CHARLES RIBBANS of 117 Fore Street, Ipswich, Tin Plate Worker, do
hereby declare the nature of this invention to be as follows:-
In carrying out my Invention I employ a chamber or reservoir of any desired
shape made preferably of light thin sheet metal. Said chamber or reservoir has at
the base a contracted portion or neck which latter would ordinarily be adapted to
the top of the lamp glass or chimney; and, be formed with a discharge opening at
top (of said chamber or reservoir).
After the lamp has been lit and consequently on the air within the chamber above
referred to becoming heated, the illuminating power of the flame will be increased
owing to the induced upward current of air.
Under another modification in accordance with my Invention the neck or contracted
portion at the base of the hot air chamber aforesaid may be adapted direct to a lamp
burner and the hot air chamber be supplemented by the addition of a second reservoir
wherein the heat arising from combustion may be utilized say for boiling or cooking
purposes.

Improvements relating to Petroleum and other Lamps.
I, 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, reference being had to the accompanying sheet of drawings in which :-
Figure 1 illustrates an elevational view of the device as applied to a lamp.
Figure 2 is a detached elevational view of said device or appliance; and Figure 3
is a sectional elevational view of the same; similar letters of reference being used
to denote like parts in the different views.
In carrying out my invention I employ a chamber or reservoir A of any desired
shape, made preferably of light thin sheet metal. Said chamber or reservoir A has at
the base thereof a contracted portion or neck B designed to move telescopically within
said chamber A to allow of its being adapted to lamp chimneys of various lengths;
and in order to prevent the neck B aforesaid from being detached from the chainber A,
the upper part of said neck is provided with a flange a Figure 3, and at the lower end
is fixed a hood & which ordinarily surrounds and overlaps the upper end of the lamp
chimney. The upper part of said chamber or reservoir A is also provided with a
short length of tube c to serve as a discharge opening for carrying off the products of
combustion. Within the neck B at the lower end, is fitted a perforated metal
diaphragm, the perforation of which may be elliptical as shown in plan at Figure 4,
or it may be of circular or other form to suit different types of lamps to which the
device according to my invention may be adapted.
After the lamp has been lit, and consequently on the air within the chamber A
above described becoming heated, the illuminating power of the flame will be
increased owing to the induced upward current of air.
As a modification of the arrangement above described, the contracted portion or
neck B at the base of the air heating chamber A may be connected direct to a lamp
burner without the interposition of a chimney, and the air heating chamber A
aforesaid be supplemented by the addition of a second reservoir wherein the beat
arising from combustion may be utilised for, say boiling or cooking purposes.
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 :-
--
First The adaptation to petroleum and other lamps of an air heating chamber

page_text: substantially as and for the purpose herein described and shown in the accompanying
drawings.
Second In the device herein described and referred to in the preceding claim
the combination therewith of a contracted portion or neck provided at the lower end
with a hood substantially as herein set forth.
