Improvements in Rendering Materials Fire-proof, and in
Extinguishing Fire,
We, LEOPOLD LITYNSKI, Proprietor, AUGUST RODAKIEWICZ, Doctor of Justice,
and FELIKS KUROWSKI, Proprietor, all of Theatre Building, Golnchowski Place,
Lemberg, Galicia, Austria, do hereby declare the nature of our said invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The present invention relates to a preparation which is intended both for the
impregnation of combustible substances: such as wood, paper, card board, textures
of all kinds, straw and such like, whereby these are rendered fireproof, as well as
for the direct extinction of conflagrations.
The preparation is made from the following substances:-Manganese-oxide, 1%
calcium-oxide, 15% potassium-hydroxide, 5%, potassium-carbonate, 25%, oxide
of sodium, (Na) 8% together with sodium-chloride 0.5% and a solution of
de-fatted quillai (2%), glue, gelatine, horn, or similar animal substances, saturated
with carbonic-acid.
The former substances are used either all together or singly, in combination with
the latter, for impregnating the combustible bodies, more or less of the above
mentioned salts being used according to the more or less combustible nature of the
articles to be impregnated.
The preparation, obtained from the above named substances, is brought into
combination with the articles to be impregnated. The articles are completely
steeped or only coated according as the impregnated articles are to be employed
for a longer or shorter time or according as they are more or less combustible.
Instead of the above mentioned substances wiz.:-manganese-oxide, calcium-
oxide, potassium-hydroxide, potassium-carbonate, oxide of sodium, chemical waste
and by-products may be employed, provided that such by-products contain the
above mentioned salts; these waste or by-products must of course be combined
with sodium chloride and a solution of defatted quillai, glue, gelatine, horn or
similar animal substances, saturated with carbonic acid.
The articles thus impregnated, of whatever class they may be, are completely
fireproof, unignitable and uninflammable.
An impregnated body will, as the tests have demonstrated, neither glow nor
burn.
Only under the direct influence of a strong fire is the article effected, and then
it only chars, without producing either flame or glow, and cannot therefore increase
the fire or assist in spreading the same.
A further and not less valuable use of this preparation is as an extinguisher for
the direct quenching of fire. For this purpose the preparation, obtained from the
above named substances is mixed with a corresponding quantity of water, and can
then be squirted upon the fire, or used in some other way for quenching the same.
The spots sprinkled with the fluid are immediately extinguished and even the
largest fire will not be kept alight, but at the most become charred.

page_text: It should be further mentioned that articles impregnated with the fluid retain
their natural colour, and consequently any article, without exception, may be
impregnated with this preparation without injury.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. The application and use of the improved preparation for the impregnation of
all kinds of combustible substances such as wood, paper, card-board, textures,
straw and the like by which the same are rendered unignitible, uninflammable and
completely fireproof, characterized by the employment separately or together and
in combination with sodium-chloride and a necessary quantity of a sufficiently
strong solution of de-fatted quillai, glue, gelatine, horn or similar animal sub-
stances and the said solution being saturated with carbonic acid and of manganese-
oxide, calcium oxide, potassium-hydroxide, potassium-carbonate and sodium-oxide
or of chemical waste or by products which contain the said salts, substantially as
and for the purposes described.
2. The application and use of the above described compound or preparation
mixed with water for the purpose of extinguishing fire, substantially as herein
before described.
