CHANDLER of Central Works, Kennington Oval, in the county of Surrey, Gas
Engineers do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in regenerative gas lamps whereby the
lighting power of the lamp is considerably increased.
In carrying out our invention we construct the burner somewhat in the manner
of what is known as an Argand or ring burner but closed at its lower part to the
centro of which is connected the supply pipe which passes up through the centre to
the top of the lamp; the body of the lamp is of the usual form and is provided
with a glass of suitable shape hinged thereto; in the said body we provide a
chamber into which the air for feeding the burner is introduced through an
opening or openings in the body; through this chamber pass a number of vertical
flue tubes serving to carry off the products of combustion; within the said chamber
we place a horizontal and annular partition in which are a number of short tubes
surrounding the said flue tubes and forming communication between the upper
and lower parts of the chamber; the central portion of the lower part of the
chamber is extended downwards to within a short distance of the burner.
The action is as follows:-
The outer air entering the chamber as hereinbefore described on its way to the
burner will be caused to travel through the upper part of the chamber and between
the hereinbefore described tubes and in its passage will become thoroughly, heated
by contact with the same; it will then pass through the downward extension and
impinging on the flame of the burner will cause the said flame to be spread out in
the form of a disc; the heat and products of combustion pass out of the lamp
through the hereinbefore described flue tubes.

We SAMUEL CHANDLER Senior, SAMUEL CHANDLER Junior and JOSIAH
CHANDLER of Central Works, Kennington Oval, in the county of Surrey, Gas
Engineers, 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 relates to an improved burner to be used in regenerative gas lamps
whereby the lighting power of the lamp is considerably increased.

In carrying out our invention we construct the burner somewhat in the manner of
what is known as an Argand or ring burner with vertical orifices for the issue of the
and closed at its lower part, to the centre of which is connected the supply pipe which
passes up through the centre to the top of the lamp; the body of the lamp is of the
usual form and is provided with a glass of suitable shape hinged thereto; in the said
body we provide a chamber into which the air for feeding the burner is introduced
through an opening or openings in the body as usual; through or around this chamber
pass a number of vertical flue tubes or passages serving to carry off the products of
combustion the central portion of the lower part of the chamber is extended
downwards to within a short distance of the burner where it is provided with a third
tube.
In order to enable our invention to be fully understood we will proceed to
describe the same by reference to the accompanying drawing in which figure 1
represents a sectional elevation of a lamp constructed according to our invention
and figure 2 is a horizontal section on line A, B, of figure 1. Similar letters in
both the figures represent similar parts.
a, is the lamp body of the usual construction, and b, the glass hinged theroto in
the ordinary manner; c, is our improved burner which consists of an Argand or
ring burner having vertical orifices for the issue of the gas closed at the lower part as
clearly shewn in figure 1, of the drawing; the burner is connected to the gas supply
pipe de, is the chamber into which the air for feeding the burner is introduced
through openings, f, in the body of the lamp and through openings or passages g,
leading directly into the chamber e; h, h, are the vertical flue tubes or passages around
the chamber e, serving to carry off the products of combustion; i, is the third tube in
the centre of the lower part of the chamber e; we make either the burner c, or the
tube i, adjustable for the purpose of allowing of regulating the space between the
upper side of the burner and the lower end of the tube i.
In a lamp constructed as above described and represented in the drawing, the
gas is supplied to the burner e, through the gas supply pipe d, and the outer air
will enter the chamber e, through the openings f, and the passages g; on its way
to the burner c, through the passages g, and chamber e, the air will become heated
by contact with the sides of the flues h; it will then pass through the downward

page_text: extension of the chamber e, in the manner usual in regenerative lamps of this type.
But our invention does not extend beyond the special form of the burner whereby the
gas
issues vertically upwards through the orifices and is caused to meet "end on
heated air issuing vertically downwards through the tube i.
the
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
wo claim is :
The improved burner hereinbefore described and represented in the drawing used in
combination with a regenerative gas lamp of the type herein described, substantially
as set forth.
