tion to be as follows:-
These Improvements apply particularly to paraffine Lamps and other Lamps usually
requiring chimneys and consists in forming the Lamp as follows.
The lamp is formed of metal or other suitable material, the foot or stand of the
lamp is constructed as the oil vessel or container over which is the air chamber
in which the wick tube is fixed, this air chamber is covered by a lid in the centre of
which is fixed the cone through which the flame passes this cone may be itself binged
if desired.
The body of the lamp is crowned with a shaft of any desired length and is con-
structed to admit no air to the flame excepting from the air chamber.
Thus perfect combustion is obtained. This construction of lamp is applicable for
magic lanterns nursery lamps and cottage table lamps as well as lanterns generally.

Improvements in Lamps and Lanterns.
We PERCY PALMER BURT and SAMUEL BRUCE EDMONDS both of Great Charles
Street Birmingham Lamp Manufacturers, 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
drawings and to the letters and figures marked thereon:-
These improvements apply particularly to paraffine lamps and other lamps usually
requiring chimneys and consist in forming the lamp as follows.
The lamp is formed of metal or other suitable material, the foot or stand of the
lamp is constructed as the oil vessel or container over which is the air chamber in
which the wick tube is fixed this air chamber is covered by a lid in the centre of
which is fixed the cone through which the flame passes, this cone may be itself hinged
if desired. The body of the lamp is crowned with a shaft of any desired length and is
constructed to admit no air to the flame excepting from the air chamber.
Thus perfect combustion is obtained.
This construction of lamp is applicable for magic lanterns nursery lamps and
cottage table lamps as well as lamps and Lanterns generally.
Referring to the Drawings
Fig. 1 is a view of a lamp with a magic lantern (shewn in outline) applied to it and
Fig. 2 a section through the lamp (a) is the oil vessel or container over which is the
air chamber (b) in which is fixed the tube (c) for the wick (w) (d) is a lid covering
the air chamber (b) hinged at (e) and having the cone (f) fixed in it or the
covering (d) may be fitted over or fixed and the cone (f) binged screwed or otherwise
loosely fitted on. The body (g) and chimney (h) of the lantern form an enclosed case
to the flame of the lamp so that it can only be fed with air rising through the
perforations (i) from the air chamber (b) which is supplied by the outer air passing.
through the openings (l.)
For other descriptions of Lanterns or lamps the form of the various parts will have
to be altered and the body (9) and chimney or shaft (h) be partially or wholely of
glass or other metal.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is
The construction of lamps for lanterns and other purposes by constructing them
substantially as herein set forth so that the burner can only be fed with air from an air
chamber.
