Improvements in Means for Producing Automatic Ignition of Gas
Issuing from Burners Furnished with Incandescent Mantles or
Hoods.
I, LEON PIERRON, of No. 101, Rue Marie Thérèse, Brussels, in the Kingdom of
Belgium, Chemist, 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 :—
This invention has for its object new means for obtaining automatic ignition of
gas issuing from burners furnished with incandescent mantles or hoods by the use
of certain igniting substances and consists principally in insuring long durability of
the said substances by modifying the constitution of the substance of the mantle
at those parts which are to be in contact with the said igniting substances in such
manner as to prevent the ulterior chemical reactions which would destroy the
efficiency of the mantles and also in arranging the igniting body outside the
mantle by means of a support admitting of the said igniting body being easily
removed and replaced or of variation of its point of contact with the mantle.
For this purpose the earthy molecules of a certain extent of the mantle are
saturated or enveloped with non-volatile and infusible oxides of acid action such
as oxides of silicon titanium tungsten molybdenum tantalum niobium and others
of like kind being such as in the Specification accompanying my application for
Patent No. 15414 of 1898 I have termed supporting elements.
At those parts of the mantle which have been thus prepared there is then
arranged an igniting substance of the platinum group as hereinafter exemplified.
The preparation of the mantle may be effected prior to or after its incineration
and in order that my invention may be properly understood I will now give
examples of these two cases with reference to the accompanying drawings.

page_text: The kinds of colouring matters which are suitable for dyeing the solution of silica
and titanium chloride are such as are entirely destroyed by calcination but are not
calcined instantly so that they remain sufficiently long to allow of the igniting
solution being applied to the dyed parts.
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 I claim :-
First A method of providing for automatic ignition of gas issuing from
burners furnished with incandescent mantles or hoods by the aid of igniting bodies
the said method consisting in surrounding or impregnating the molecules of a
portion or portions of the mantle itself with oxides of silicon titanium niobium
tantalum tungsten or other suitable infusible and non-volatile oxides of acid action,
in disposing adjacently to the impregnated part of the mantle an igniting body or
igniting bodies, and in applying to the said part at the point nearest to the igniting
body or bodies and extending outwardly therefrom threads or spots or strokes of a
platinous or other analogous substance either alone or combined with oxides of
acid action.
:-
Secondly A method of carrying out the invention defined in the foregoing
claim consisting in producing marks or lines upon the mantle by means of a solution
of oxides of acid action prior to incineration of the mantle the said marks or lines
starting from any given point, in placing upon or adjacently to the mantle at the
point from which the said marks or lines start an igniting body or an igniting tissue,
and in passing into the tissue of the mantle at the places where the said marks or
lines are made wires or threads of a platinous or other analogous substance either
alone or combined with oxides of acid action.
Thirdly-A method of carrying out the invention defined in the first claim
consisting in producing a spot or in making marks or lines starting from any point
on the mantle after its incineration by means of a solution of oxides of acid action
the solution being afterwards calcined or not, then applying at the parts thus
prepared a solution or paste of a platinous or other analogous substance either alone
or combined with oxides of acid action, and in finally applying an igniting body on
or supporting such body contiguously to the part of the mantle where the marks or
lines are made or from which the marks or lines start.
Fourthly In the methods of igniting defined in the first second and third claims
the application of any suitable igniting body contiguously to the part of the mantle
which has been impregnated with the igniting liquid or to which have been applied
successively first a supporting element solution and subsequently an igniting
element solution in such manner that the said igniting body may be easily removed
and replaced or its point of contact with the mantle changed by arranging the said
body in a suitable support or by suspending it by means of a wire from the support
of the inantle as hereinbefore described and illustrated in Figures 2 and 3 of the
accompanying drawing.
