PROVISIONAL SPECIFICATION.
An Improvement in Oil Vapour Lamps.
We, THE LUCIGEN LIGHT COMPANY LIMITED, and CHARLES ANTHONY
DUVALL, both of Page Street, Westminster, in the County of Middlesex,
Manufacturers, do hereby declare the nature of this invention to be as follows:-
Our invention relates to lamps of that kind in which oil vapour is burned, this
vapour being generated from oil by the heat of the lamp frame."
We supply the oil to an annular chamber which is connected to an upper annular
chamber by a number of vertical tubes and we provide the upper chamber with
several tangential openings by which tools can be inserted to clear out the carbon
deposit, these openings being tightly closed when the lamp is in use.
From about
the top of one of the tubes which connect the two chambers a tube descends and
bends inwards and upwards terminating in a burner central with the annular
chambers but at some distance below the lower chamber.
The burner may have above it a suitable cone.
The beat of the flame acting on the annular chambers and their connecting tubes
vaporises the oil fed thereto and the vapour descends to the burner where it is
ignited. For the purpose of starting the lamp, we supply it in the first place with
a quantity of naphtha or other volatile combustible, and kindle some of this fluid in
a shallow basin below the burner.

COMPLETE SPECIFICATION.
An Improvement in Oil Vapour Lamps.
We, THE LUCIGEN LIGHT COMPANY LIMITED, and CHARLES ANTHONY
DUVALL, both of Page Street, Westminster, in the County of Middlesex,
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 :-
Our invention relates to lamps of that kind in which oil vapour is burned, this
vapour being generated from oil by the heat of the lamp flame.
We supply the oil to an annular chamber which is connected to an upper annular
chamber by a number of vertical tubes and we provide the upper chamber with
several tangential openings by which tools can be inserted to clear out the carbon
deposit, these openings being tightly closed when the lamp is in use. From about.
the top of one of the tubes which connect the two chambers a tube descends
and bends inwards and upwards terminating in a burner central with the annular
chambers but at some distance below the lower chamber.
The burner may have above it a suitable cone.
The heat of the flame acting on the annular chambers and their connecting tubes
vaporises the oil fed thereto and the vapour descends to the burner where it is
ignited. For the purpose of starting the lamp, we supply it in the first place with
a quantity of naphtha or other volatile combustible, and kindle some of this fluid
in a shallow basin below the burner.
Fig. 1 of the accompanying drawing is a vertical section of a lamp according to
this invention,

page_text: A is the annular chamber connected by vertical tubes B B with the polygonal
chamber which has tangential openings for the insertion of tools for cleaning
the passages which openings when the lamp is in use are closed tightly by screw
plugs P.
E is the cover of the annular chamber A, the joint being made with an asbestos
or other suitable washer. F is the pipe which conveys the vapour as it is generated
to the jet or burner G. H is the cone in which atmospheric air mixes with the gas
issuing from the jet G. Combustion takes place at or about the top of the cone
at K, additional air being supplied to the flame by the annular passage around the
top of the cone.
Lis the supply pipe for the oil from the tank or other reservoir. M is a strainer
for preventing foreign matter from passing with the oil to the burner. This
strainer is contained in the case N which is closed by plug O.
S is the dish to contain oil which is kindled for heating up the burner before
lighting it. Qis a casing enclosing the entire burner having a door R for access
to the jet.
The lighting of the lamp is effected as follows:-
Volatile oil is introduced into the burner through the strainer box N and the
plug O is closed. Some oil is also poured into dish S and a light is applied to the
latter.
The burner soon becomes heated and the gas or vapour from the volatile oil in
the burner issues at (and is kindled its flame heating up the burner. The heavier
oil is then supplied from the tank or reservoir maintaining the combustion of the
lamp.
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 we
claim is :-
:-
An oil vapour lamp constructed substantially as herein described with reference
to the accompanying drawings.
