Improved Burner for Oil Lamps.
I, CECIL THROCKMORTON, of "Greylands," Glennies Creek, near Singleton, in the
Colony of New South Wales, Gentleman, do hereby declare the nature of this
invention for "Improved Burner for Oil Lamps" 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 for oil lamps which though specially
devised for lamps such as those for domestic purposes in which kerosene paraffine
or like high grade oil is used is yet applicable to all lamps in which hydro carbon
oils more or less easily vaporised are used.
This improved burner for oil lamps consists of two main parts a tip and a
vaporising cell the former forming the top of the latter the bottom of which latter
is in connection with an oil reservoir. The tip is made of refractory heat-
conducting material of more or less porous nature such as plaster of Paris or such
as fireclay or the like mixed with combustible material but out of which the said
combustible material has been burnt. This tip is perforated and is firmly fixed to
the top of the vaporising cell which vaporising, cell is filled or nearly filled with
fibrous or spongy material such as tow or cotton-waste or the like or with other
material which will split up or divide the oil.
In one construction of this improved burner which is used when the oil reservoir is
above the level of the burner the bottom of the vaporising cell is connected to said
reservoir by a bent pipe having a regulating tap or other device such as a bird
fountain connection or other means for regulating the amount of oil supplied
through the bent pipe to the burner. In a modified construction of this burner
which is used when the oil reservoir is below the burner as in ordinary hand or table
lamps the vaporising cell is affixed to the top of the wick tube and the ordinary wick
terminates in the fibrous or spongy filling in said cell.
In order to the saving of the oil to the prevention of the charring or burning
of the filling material of the cell and to the speedy extinguishment of the lamp a
movable head is combined with the burner adapted to stand clear of the tip and
to closely fit over the tip when required to cut off the supply of oxygen thereto.
But in order that this invention may be clearly understood reference will now be
made to the drawings herewith in which Figures 1 and 2 are cross sectional
elevation at right angles respectively of one construction of this improved burner
for oil lamps specially devised for use on a lamp having the oil reservoir above the
level of the burner and these views show the extinguishing cap or hood in position
closed over the tip. Figures 3 and 4 are central sectional elevation and plan
respectively of a modified construction of burner for use on an ordinary hand or
table lamp or a lamp having its oil reservoir below its burner and in these views
the extinguishing cap or hood is shown as elevated clear of the tip and in
Figure 4 the burner cone is removed. Figure 5 is enlarged cross sectional
elevation of the burner Figure 6 a plan of the tip and Figure 7 a longitudinal
elevation of the burner.
A is the tip B the vaporising chamber or cell C the oil supply pipe or wick
tube Dan ordinary slotted burner cone and E an ordinary chimney gallery or

page_text: support. The tip A of refractory and porous material has perforations A* as
shown medially of its length and it has grooves A2 into which spring the upper
edges B² of the vaporising cell B thus firmly holding it in position. The lower
parts A³ of this tip extend downwardly as shown into the filing B₁ of the vaporising
chamber said filling being of a fibrous or spongy nature such as the materials
before mentioned or asbestos or any other material which will split up or divide
the oil which enters the vaporising cell. In the burners shown in Figures 1 and 2
this vaporising cell B is connected with branch pipes C to the main supply pipe C
which has tap or valve C² or other contrivance for regulating the supply of oil to
said vaporising cell. In the construction of burner shown in Figures 3 and 4 this
vaporising cell B has an inset channel or socket B³ adapted to tightly fit over the top
of the wick tube which wick tube contains an ordinary wick C as shown dipping
into the oil reservoir. On the side of the vaporising cell B is hinged at F1 the
hood or cap F and extending therefrom is a lever F2 having a connecting rod F3 to
lever F terminating in a thumb piece F³.
In use (the regulating tap or valve of burner shown in Figures 1 and 2 being
turned on) the light is applied to the porous tip when the oil contained therein
burns and so heats such tip and its downward extensions A³-causing the oil in
chamber or cell B to vaporise and this escaping through the perforations A* in
the tip burns and emits a good and steady illuminating flame.
In extinguishing the lamp the thumb piece F5 is pushed to operate lever F* which
operates rod F3 and lever F2 causing the cap or hood F to fall over on its hinge F
and closely fit the tip A and thus cut off the supply of oxygen and smother or
extinguish the flame. In using the burners shown in Figures 1 and 2 it is
necessary to cut off the flow of oil to the burner by manipulating the tap or
valve C2 or other regulating contrivances.
It is to be understood that though I have shown what I consider to be the best
constructions of this improved burner yet I do not confine myself to the precise
details described and illustrated so long as the nature of this invention be retained.
Having now particularly described and explained the nature of my invention
and in what manner the same is to be performed I declare that what I
claim is :-
First. An improved burner for oil lamps consisting essentially of a perforated porous
refractory tip set above a vaporising cell (containing fibrous or spongy or other oil
splitting up or dividing material) having connection with an oil supply substantially
as herein described and explained.
Second. The combination with a burner constructed as set out in the preceding
(first) claiming clause of a hood or cap adapted to stand clear of the tip and
when required to closely fit over said tip substantially as herein described and
explained.
Third. The particular construction of improved burner for oil lamps as illustrated
in Figures 1 and 2 of the drawings substantially as herein described and explained.
Fourth. The particular construction of improved burner for oil lamps as illustrated
in Figures 3 and 4 of the drawings substantially as herein described and explained.
