Improvements in Illuminant Appliances for Gas and other Burners.
I JOHN FOYSTER BURGESS of No. 19 Wakefield Street Regent Square London
in the County of Middlesex Clerk do hereby declare the nature of this invention
to be as follows:-
My invention relates to the manufacture of Illuminant Appliances such as
Mantels & the like, that are to be made with a vegetable substance that is termed
Mucilage. This substance is by virtue of the solution hereinafter described, pro-
duced in a finely devided condition, in which condition when it is applied to Gas
& other Burners it gives out a full brilliant & powerful light and it does not
consume away, but remains efficient for a long time, & when heated to incan-
descence it is fairly tough & pliable, & not apt to rupture through vibration &
the like. Mucilage can also be combined with rare earths or lime and the like
for the manufacture of said Illuminant Appliances for Gas and other burners as
hereinafter described.
I
For this purpose I take Mucilage or substances that contain Mucilage.
subject the Mucilage or the substances that contain Mucilage, to a great heat,
until all combustible materials are consumed.
I then take the non-combustible ashes that are left, dissolve the soluble portion
of them in pure or aqueous Acetate or Nitric Acid; I then strain the solution.
The Nitrious solution must in any case be freely diluted before dipping the
combustible material shape of appliances required into it, so as not to destroy
them; but the Acetate sclution can be either aqueous or pure as convenient,
according to the quantity of vegetable substance contained in it. The proportion
of ashes to be put into the acids, depend upon various circumstances, as that,
some substances will give a larger quantity of soluble ashes than others.
The heat used in consuming the combustible portion of the vegetable substances
will also govern the production of soluble ashes to a certain extent, & the thick-
ness & nature of the materials to be impregnated by the solution, will also govern
the proportion of ashes to be dissolved in the acids, so that a weak solution &
a stout material or a strong solution and a thin material will give required results.
The vegetable matter in this solution will give a full brilliant & powerful light
when impregnated into any material that is of a porous nature and that burn
right away, such as wood, Fibres, Cotton and the like, which when burnt leave
only the refractory vegetable substances behind.
For producing the frame of vegetable matter for Illuminant appliances, I use
the ordinary cotton mantel and the like. The cotton form of the appliance
required, is dipped in the solution and when dried and ignited, all the combustible
materials are consumed, leaving only the non-combustible refractory vegetable
substance which retains the form of the appliance impregnated, also the grain
of the materials into which it was impregnated. This substance as hereinbefore
stated; when heated to incandescence, emits a full, brilliant & powerful light,
;

page_text: the substance being tough and pliable when heated, and fairly hard when cold;
therefore, it is not apt to rupture from various causes, such as vibrations and the
like, to which these appliances are likely to be subjected.
The ashes of this vegetable substance can also be combined with rare earths or
lime & the like, being treated in the same manner with acids as hereinbefore set
forth, for impregnating porous materials, mantels, and the like, for illuminating
appliances for incandescent lighting on gas and other burners, thereby enhancing
their illuminating powers and strengthening the frame of oxides thus making
these appliances less liable to rupture from the multifarious causes that are apt
to occur during the life of same.

I, JOHN FOYSTER BURGESS of No. 19 Wakefield Street Regents Square London
in the County of Middlesex Clerk 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:-

until all combustible materials are consumed.

I then take the non-combustible ashes that are left, dissolve the soluble portion
of them in pure or aqueous Acetate or Nitric Acid; I then strain the solution.
The Nitrous solution must in any case be freely diluted before dipping the
combustible material shape of appliance required into it, so as not to destroy
them; but the Acetate solution can be either aqueous or pure as convenient,
according to the quantity of vegetable substance contained in it. The proportion
of ashes to be put into the acids, depends upon various circumstances, as that,
some substances will give a larger quantity of soluble ashes than others.
The heat used in consuming the combustible portion of the vegetable substances
will also govern the production of soluble ashes to a certain extent, & the thick-
ness & nature of the materials to be impregnated by the solution, will also govern
the proportion of the ashes to be dissolved in the acids, so that a weak solution and
a stout material or a strong solution and a thin material will give required results.
The vegetable matter in this solution will give a full brilliant & powerful light
when impregnated into any material that is of a porous nature and that burn
right away, such as wood, Fibres, Cotton and the like, which when burnt leave
only the refractory vegetable substances.
For producing the frame of vegetable matter for Illuminant appliances, I use
the ordinary cotton mantel and the like. The cotton form of the appliance

substance which retains the form of the appliance impregnated, also the grain

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:-
(1) The manufacture and use of Illuminant appliances such as Mantels and the
like, for gas and other burners, impregnated with a vegetable substance sub-
stantially as herein described & set forth.
(2) The manufacture and use of Illuminant appliances such as Mantels & the
like, for gas & other burners impregnated with a combination of a vegetable sub-
stance and rare earths or lime and the like, substantially as herein set forth.
(3) The manufacture and use of a solution prepared with a refractory vegetable
substance for impregnating porous materials for the manufacture of Illuminant
appliances for use on gas and other burners, substantially as herein described
and set forth.
.
(4) The manufacture & use of a solution prepared with a combination of a
refractory vegetable substance and rare earths or lime & the like, for impregnating
porous materials for the manufacture of illuminant appliances for use on gas
other burners substantially as herein stated.
