I CHARLES HENRY MEUBN of 97 Cannon Street in the City and County of
London, Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in lamps and is more especially adapted
for those in which kerosene is burut, and which do not necessitato the use of any
chimney-such as the Barton lamp, and it consists in the provision of a small air
chamber underneath and around the burne in connection with an an passago
aanged with an inlet at the bottom of the lamp, and its object is to render the
lamp perfectly safe and not liable to be extinguished with any ordinary usage.
I attain this object by forming a small air chamber around and underneath the
burner of the lamp, and to the air chambo I connect an au passage which may
either be fixed along the side aud top of the reservoir or cistern, or may consist
of one or more air pipes passing through the cistern for the purpose of supply ing
the lamp with air for combustion. Though the bottom of the lamp I form by
punching or otherwise a hole corresponding in size to the air passage which is
suitably proportioned to the power of the light.
Lamps constructed according to my invention have the advantages of freedom
from danger and of non-liability to extinction with ordinary usage, a feature
specially desirable in the case of hand lamps for use during shunting operations on
railwaye. My improvements are applicable also to engine head lamps, side or tail-
lamps and practically to all lamps used on the outside of railway trains or tram
cars; it can also be applied to lamps used on carts or other vehicles for street
traffic, thus rendering the use of kerosene oil practicable for many purposes for
which it has not hitherto been successfully applied.

I, CHARLES HENRY MEUEN, of 97 Cannon Street, in the City and County of
London, Merchant, 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 :-
My invention relates to improvements in lamps, and is more especially adapted
for those in which kerosene or other mineral oils are burnt, and which do not
necessitate the use of any chimney,-such as the Barton lamp, and it consists in
the provision of a small au chamber underneath and around the burner in con-
nection with an air passage arranged with an inlet at the bottom of the lamp, and
[Price 8d.1

page_text: its object is to render the lamp perfectly safe and not liable to be extinguished with
any ordinary usage.
In order that my invention may be more clearly understood, reference is had to
the accompanying drawings upon which,-
Figure 1 is a side elevation of a lamp with my improvements applied thereto;
Figue 2 shewing the an-chamber and passage in section.
Figure 3 is a plan of Figure 1.
In carrying out my invention I form underneath and around the burner of the
lamp, a small air-chamber A, and to this au-chamber I connect an an-passage B,
which may be fixed along the side and top of the reservoir or cistern C, as shewn
on the drawings,-
,-or it may consist of one or more air pipes passing through the
cistern, for the purpose of supplying the lamp with air for combustion.
Though the bottom of the lamp 1 form-by punching or otherwise-a hole or
air-inlet D, corresponding in size to the air passage B, which is suitably proportioned
to the power of the light.
Lamps constructed according to my invention have the advantages of freedom
from danger and of non-liability to extinction with ordinary usage, a feature
specially desuable in the case of hand-lamps for use during shunting operations on
railways.
My improvements are applicable also to engine head-lamps, sido or tail-lamps,
and practically to all lamps used on the outside of railway trains or tiam-cais; it
can also be applied to lamps used on caits or other vehicles for street traffic, thus
tendering the use of kerosene oil or other mineral oils practicable for many
pui poses for which they have not been hither to successfully applied.
Having now particularly described and ascertained the nature of my said inven-
Lion, and in what mauuer the same is to be performed, I declare that what I
claim is :-
1. In lamps for buning kerosene or other oils, the arrangement of an ait-
chamber C connected with one or more air-supply passages B, as and for the
purposes described.
