Improvements in Oil Lamps.
I FREDERICK ERNEST TOWNSEND of 7 Stuart Street Luton Beds Shop Assistant,
and SAMUEL TOWNSEND of 7 Stuart Street Luton Beds Botanical Druggist do hereby
declare the nature of this invention to be as follows:-
--
This Invention relates to Improvements in Oil Lamps. We proceed thus
The Oil Vessel is constructed of metal or other suitable material the fluid capacity is
one pint more or less. An inner tube is inserted in the same either of a round oval
or rectangular shape. We prefer the later shape, tapering from the top to about half
the distance of the depth of the said vessel, this being the length of the said inner
tube. The opening at the bottom of the tube is large enough to allow the wick or
wicks to pass freely through the same into the said oil vessel. Near the top of this
tube one or more pipes are inserted and made secure the same is brought either in a
straight slanting or curved direction and passed through the outside of the oil vessel,
and permanently secured thereto. The top end of the said inner tube is joined to
the top of the said oil vessel and made airtight at the said joint or connection. On
one side of the oil vessel a mouth piece is inserted. The top of the same is not higher
than the bottom of the said inner tube. Into the said mouth piece is inserted a screw
thread a screw stoper or plug is fitted in the same the oil is poured into the mouth
piece the surface of the same rising not higher than the bottom of the inner tube.
The Burner of the said Lamp is constructed of metal, having two air shafts one of
the same is placed on each side of the wick tube or tubes passing through to the
bottom of the Burner. The wick tube or tubes pass through the Burner into the
inner tube of the oil vessel, to the distance of one inch more or less.
We prefer
the said tube or tubes to be rather higher than the air shafts, on the top side of the
Burner and below the opening of the flame cap or hood. The same are made to allow
of a wick or wicks of one inch more or less in width. The outside of the Burner is
peforated or closed we prefer the former plan as this allows the air to enter from the
outside of the Burner causing a brighter light. A peforated plato is fitted around
the air shafts and under the bottom rim of the flame cap or hood the wick or wicks are
raised or lowered by a toothed wheel or wheels. A notched rim or flange projecting
upwards holds the glass (or chimney) in position.
The said Burner is made to fasten on
the oil vessel and to be removed from the same either by a screw or a non screw
socket we prefer the later plan as the wick or wicks are kept straighter. The above
mentioned pipes are for conveying air to the inside of the Lamp the air passes from
thence up the air shafts and mixes with the flame previous to the same passing
through the opening of the flame cap or hood, causing a more perfect combustion and
increase of light. The heated gases or vapours are not confined in the Lamp therefore
the Lamp cannot explode.

COMPLETE SPECIFICATION.
Improvements in Oil Lamps.
We, FREDERICK ERNEST TOWNSEND, of 7 Stuart Street, Luton Beds Shop Assistant,
and SAMUEL TOWNSEND, of 7 Stuart Street Luton Beds, Botanical Druggist, 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 improvements in hydrocarbon Oil Lamps with air shafts,

page_text: directing the pure air into the flame for the purpose of obtaining an increase of light;
and to permit the gases or vapours from the oil to escape and thereby prevent
explosions.
And in order that our invention may be thoroughly understood we now proceed to
describe the accompanying drawing thereof, reference being had to letters and figures
marked thereon.
Figure 1 represents a section of the burner and oil container, with the various
tubes 1, to admit the puro air, and the tubes F, F, to permit the oil gas to escape, and
is constructed of metal or any other suitable material."
An inner tube E is inserted in the container, either of a round, oval, or rectangular
shape tapering from the collar about half the distance of the depth of the said con-
tainer, with an opening at the bottom large enough to allow the wick or wicks to pass
freely through the same into the oil below the oil line H. Near the top of this tube
one or more pipes I, are inserted either perpendicular, slanting, or curved, and passed
through the outside of the container J, and secured thereto, and made air tight at the
joints, or connections.
On one side of the container a mouth piece K is inserted, the top of the same is not
above the level of the inner tube E, provided with a scrowed stopper or plug. The
oil is poured into the mouth piece, the surface of the same rising not higher than
the level of line H.
The burner of the said lamp is constructed of metal, having two air shafts C, C,
connected with or socket itself into the collar or tube E. Ono air shaft is placed
each side of the wick tube B, in either a single wick, duplex, round, or any other
wick tube, passing through to the bottom of the burner. The wick tube B pass
through the burner into the inner tube E of the container, to any suitable distance.
The wick tube or tubes if preferable may be rather higher than the air shafts C, C,
and below the opening in the cap or hood A. The wind guard D is perforated in
the usual manner, with a perforated disc or tray in the inside to catch any car-
bonized wick.
The burner is made to fasten on the container, and to be removed from the same
either by a socket or a screw.
The aforesaid pipes C, C, are for conveying pure air to the inside of the burner,
the air travelling as indicated by arrows in the tubes I, I, into the tube E and
ascend the shafts C, C, and mixes with the flame previous to the same passing the
slot in the cap A, thereby giving a more perfect combustion and increase of illu-
minating power.
The heated gases or vapours are not confined as now in the ordinary lamp ſount,
but is provided with tubes F, F, to permit free ventilation.
Our invention is so constructed that should the lamp fall down, the oil would flow
into the upper part of the container G, G, and thereby cut off the supply of oil down
the wick tube.
The container is fixed to a stand L for a table lamp or may be fixed to any other
fittings such as brackets, pendants, or the like.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what
we claim is:-
First. The combination of the burner and container constructed with air tubes
leading to an inner chamber E, and opening into the same, with vent tubes F, F,
leading to the outside of the oil vessel, and the air shafts C, C, passed through the
inside of the burner, to cause a free circulation of pure air to travel through the
lamp into the flame, to obtain an increase of illuminating power, substantially as
herein described and according to the accompanying drawing.
Secondly. The non-confinement of the gas or vapour from the oil in the container,
to prevent explosions substantially as herein described.
Thirdly. The construction of the container, that when the same is held bottom
upwards or is knocked over the contents of the oil vessel cannot run through the

page_text: burner into the flame; and the flame is instantaneously drawn into or under the flame
cap or hood A, and retained there until placed in its proper position, substantially as
herein described.
Fourthly. We claim to attach our invention to any description of lamp or burner,
with one wick tube or any number of wick tubes, substantially as herein described.
