An Improved Method of and Apparatus for Generating Vapour or
Gas from Oil, together with Burners for Burning the same in
Lighthouse and other Lamps.
I WILLIAM WAKEFIELD of 4 Upper Grand Canal Street in the city of Dublin
Engineer Ireland do hereby declare the nature of my said invention for "AN IMPROVED
METHOD. OF, AND APPARATUS FOR GENERATING VAPOUR OR GAS FROM OIL, TOGETHER
WITH BURNERS FOR BURNING THE SAME IN LIGHTHOUSE AND OTHER LAMPS," and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement and accompanying drawings, that is
to say:
The object of this invention is to generate vapour or gas from petroleum, or other
oil, the apparatus for effecting which is self acting and feeding or supplying the
construction of the burners together with the method of supplying the vapour being
such as to produce a more perfect combustion of such vapour or gas, than has been
hitherto effected, without the use of a chimney.
The nature of the invention together with its mode of action will be clearly
understood by aid of the following description and accompanying drawings.
Fig. I is a vertical elevation seen in section, of a complete lamp, with retort or
vapouriser for the generation of vapour or gas from the petroleum or other oil, with
vapour burner. In this case the gas is supplied direct from the vapouriser or retort as
hereafter described.
Fig. 2. is a plan of the vapour burner seen from above.
Fig. 3. represents a retort constructed for connection with an ordinary gas holder,
and is made to fit the lamp Fig. 1.
The vapour burner consists of a variable number of concentric tubular rings A
arranged in pairs at equidistant intervals or spaces, the lower ends of these concentric
tubes are united by metal rings B, which put the tubes A, at this part in
communication with the vertical pipes C, the lower extremities of the pipes C, are
connected and communicate with the closed chamber D.
The upper ends of the concentric tubes A, are also connected with metal rings E,
'

page_text: these latter are perforated by drilling a number of holes round them as in Argand
burners, these rings E, form the top of the burner.
The oil is contained in a tank or reservoir conveniently situated for the purpose,
and is conducted thence by slowly flowing through a pipe F, communicating with a
vapourising retort G.
In starting the lamp a lighted lamp or fuse is first placed beneath the vapouriser G,
or retort, the heat evaporates the oil into vapour or gas, which passing up the
pipes H. H. then descends the pipe L. and entering the chamber D through holes in
the vertical tubes or pipes C, to the concentric rings or tubes A, and
the pipe I passes burner or rings E through the holes therein, where the vapour or
thence it reaches
gas is ignited, and mixing with the surrounding atinosphere the vapour or gas burns
with a more perfect combustion than hitherto, without the aid of a chimney.
From the above description it will be observed that the whole apparatus is automatic
in its action.
By putting the retort G or vaporiser in direct communication with an ordinary
gasholder and purifier, the gas can be conducted to the burner by means of suitable
pipes and a cock or tap, and the lamp can be lighted at any time, or extinguished
by either opening or closing the tap.
Fig. 3 shows a retort with pipe L, communicating with an ordinary gas holder (not
shown in the drawings) this retort can be substituted for that Fig. 1.
Ilaving now particularly described and ascertained the nature of my said invention,
and in what manner the same is or may be performed I do not restrict myself to any
particular form dimensions or material of construction of either vapouriser, or vapour
burner, as these may vary without departing from the principle of action thereof,
but what I claim is
The method of generating vapour or gas from petroleum or other oil by means of
a lighted lamp or burner situated beneath a vapouriser or retort, so that the lamp
produces by this means the gas or vapour requisite for its own consumption, or for
other uso.
The petroleum or other oil being supplied from a receptacle to the retort or
vapouriser by means of a pipe from one to the other.
I also claim the method of supplying the vapour or gas to the vapouriser by means
of a tube or pipe connecting the retort with an ordinary gas holder the whole as and
for the purposes herein setforth.
