Improvements in Rendering Substances Incombustible.
I, ALBERTO ISSEL, of 11 Via Roma Genoa in the Kingdom of Italy, Furniture
Manufacturer, 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 :-
My invention relates to a process for fire-proofing the several materials (wood,
pasteboard, textile fibres, woven fabrics and the like) which are employed in
constructions liable to the danger of fire, such as partition works and decks of
ships, sheds, railway carriages, theatrical implements, pieces of furniture and
the like.
The materials to be made incombustible are previously reduced to the due
dimensions and afterwards put into a drying place, in order to remove wholly
their moisture.
Such operation is most important, as, but for it, materials would not intimately
absorb the fireproofing solutions, and consequently an imperfect incombustibility
would be obtained.
The dry goods are then immersed into one of the following solutions, which is
to be kept in uninterrupted ebullition, during from six to twenty hours, according
to the nature of the materials and dimensions of pieces.
The solution for non resinous woods, textile fibres and tissues, is composed of :-

page_text: matters, and when in case of fire a great many persons would be placed in
serious danger, as happens frequently and particularly on board steamers and in
theatres.
It will be observed that the process I have invented consists of :-
1stly. The complete desiccation of the materials to be rendered incombustible.
2ndly. The immersion. cf the dried materials into one of the above described
solutions during a lapse of time of from six to twenty hours according to the
nature of the material and dimensions of the pieces.
3rdly. The keeping of the solution in uninterrupted ebullition during the whole
period of immersion.
4thly. The drying of the goods on their removal from the bath.
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 improvements in rendering substances incombustible herein before
.described.
2. Rendering wood, pasteboard, textile-fibres, woven-fabrics and other like goods
incombustible or uninflammable by 1st complete desiccation, 2nd immersion in the
appropriate one of the solutions hereinbefore described, and 3rd boiling the same
therein for the period of time indicated, and 4th re-drying the material all
substantially as hereinbefore set forth.
3. For the purpose of rendering materials such as those above named incom-
bustible or uninflammable the use of one of the solutions herein before described
composed of the ingredients named in the proportions or nearly the proportions
.herein before set forth.
4. Rendering substances, such as those indicated, uninflammable or incombustible
by means of the solutions, or one of them, above described and treatment
substantially as hereinbefore described.
