I JAMES LEWIS of 153 Brockley Road Brockley in the County of Surrey
Engineer do hereby declare the nature of my invention for "IMPROVEMENTS IN
GAS BURNERS FOR CONSUMING A MIXTURE OF GAS AND AIR FOR ILLUMINATING
AND HEATING PURPOSES "to be as follows:-
My improvements relate to that class of gas burners in which 'a mixture of gas
and air is employed to render a cap of platinum wire gauze or perforated platinum
plates incandescent for, the production of light and heat for which Patents have
been granted to me.
In the specification of Lettera Patent granted to me dated 26th February 1884
No 3984 gas burners of this character were described as surrounded by tubes or
chambers to produce induced currents of air the tube or chimney being surmounted
by another tube or chimney of larger diameter than the one below.
Now I find that the chimney to the chamber which surrounds the burner can be
dispensed with when the pressure from the main is sufficient to produce an induced
current of air capable of rendering the platinum cap of the burner incandescent.
I also find that the height of the chimney or the capacity of the chamber which
surrounds the burner can be regulated or governed in accordance with the pressure
of the gas supplied from the main, any variation in the pressure of gas being
regulated by the admission of air to the chimney globe or chamber surrounding
the burner.

I, JAMES LEWIS of 153-Brockley Road Brockley in the County of Surrey
Engineer do hereby declare the nature of my invention for "IMPROVEMENTS IN

particularly described and ascertained in and by the following statement :-

Now I find that the chimney, to the chamber which surrounds the burner can be

When the pressure of the gas from the main is too low to produce
current of sufficient strength to render the platinum gauze cap incandescent the
gas. from the meter can be passed through a power meter to impart sufficient
pressure to the gas in its passage to the burner or burners. By this means the
ordinary fittings may be used in combination with my improved burners without
the use of the extra chimney.
°
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The improved arrangement of gas burners for consuming a mixture of gas and
air arranged to act substantially in the manner and for the purposes herein before
fully described.
