PROVISIONAL SPECIFICATION.
A Method of Burning Acetylene Gas or other very rich
Hydrocarbon Gas.
I, JOHN RICHARDSON WIGHAM of 33 Capel Street Dublin, Lighthouse
Engineer do hereby declare the nature of this invention to be as follows:-
My invention consists in forcing the gas to the point of combustion through a
tube or tubes with fine needle hole outlets, such outlets being of the size of what is
technically known as No. seven or smaller of English make, through which the gas
is emitted vertically or obliquely in straight jets in contradistinction to fish tail jets
or batswing jets which are frequently used with ordinary gas burners, the straight
jets of gas being either single or when used vertically or obliquely for lighthouse
or other purposes where powerful lights are required, arranged in groups in such
number as may be necessary for the size of light required, placed closely side by
side or concentrically so as to cause it to have an appearance somewhat similar to
that produced by an Argand burner, but differing from the light produced by an
Argand burner, for example not having a chimney glass surrounding the flame.
Over each single jet of gas or group of jets I suspend a tube of mica, glass or other
suitable material by which the atmospheric air is sucked in by the upward current
of air heated by the gas jets so as to render the flame smokeless and steady.
I surround these tubes with a cover of perforated zinc, copper or other material,
conical in shape and having a hottom of the same perforated material, the object
of the perforated covering being to check the current of air to the tubes and to
impart to it before coming into contact with the flame a certain amount of heat.
which is useful to the development of the light.
Dated this 25th day of February 1896.

I, JOHN RICHARDSON WIGHAM of 33 Capel Street, Dublin Lighthouse
Engineer 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 :-

current of air heated by the gas jets so as to render the flame smokeless and steady.
I surround these burner tubes with a cover of perforated zinc, copper or other
material, conical in shape and having a bottom of the same perforated material,
the object of the perforated covering being to check the current of air to the
tubes and to impart to it before coming into contact with the flame a certain
amount of heat which is useful to the development of the light.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The method of burning acetylene gas as above described.
