Improvements in the Manufacture of Incandescence Bodies for
Illuminating Purposes.
I WILLIAM HUMPHREY WHEATLEY, of the Firm of Wheatley & Mackenzie,
of 40 Chancery Lane, London, Engineers and Patent Agents, do hereby declare
the nature of this invention a communication to me from Charles Schmid, of
47 Boulevard Anspach, Brussels, Chemist-to be as follows:-
This invention has for its object the production of hoods or mantles for gas or
other burners which, by the action of the flame of the burner, are rendered
incandescent and thereby greatly increase the illuminating power of the flame.
According to my invention I impregnate the hood or mantle, which may be made
of any suitable fabric, with the solutions of salts hereinafter specified, the mantle
being afterwards subjected to the heat of a flame in the ordinary manner so that
the fabric is consumed, while the frame or skeleton, consisting chiefly of the oxides
of the metals employed, remains, and which when heated to incandescence, emits a
powerful light.
The formula of the two solutions to which my invention relates, and which I
have found to give excellent results in practice are as follows:
Magnesia
Zirconium nitrate
4 parts

The hood or mantle having been made of any suitable fabric to the desired form
is saturated in an aqueous solution made according to either of these formulæ and
dried in the ordinary manner when it is fit for use, the first application of a flame
consuming the fibrous constituent and leaving only the frame or skeleton of metallic
oxides remaining.

I, WILLIAM HUMPHREY WHEATLEY, of the Firm of Wheatley & Mackenzie,
of 40 Chancery Lane, London, Engineers and Patent Agents, do hereby declare
the nature of this invention-a communication to me from Charles Schmid, of
47 Boulevard Anspach, Brussels, Chemist-to be particularly described and
ascertained in and by the following statement:-
This invention has for its object the production of hoods or mantles for gas or

being afterwards subjected to the heat of a flame in the ordinary manner so that
the fabric is consumed while the frame or skeleton, consisting chiefly of the oxides
of the metals employed, remains and which, when heated to incandescence, emits a
powerful light.

is saturated in an aqueous solution made according to either of these formulæ and
dried in the ordinary manner when it is fit for use, the first application of a flame
consuming the fibrous constituent and leaving only the frame or skeleton of metallic

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 manufacture of incandescence bodies for illuminating purposes impregnated
with substances named substantially according to either of the two formulæ above
given.
