Improvements in Fire Proofing Composition.
I, GUSTAVE XAVIER DIME, residing at 216, W. 108th Street, in the City of New
York, in the County of New York and State of New York, United States of
America, Hotel Manager, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My new composition is designed for use in the treatment of wood, fabrics, laces,
and other and similar articles, and consists of the following ingredients combined
in the proportions stated.
Chloride of Ammonia
Microcosmic Salt
15 parts.
1 part.
The microcosmic salt above specified may be used either in a dry state or in the
form of a concentrated solution, and in practice, said ingredients are thoroughly
mingled by agitating or otherwise.
If wood is to be treated or rendered fire proof, the said composition is dissolved
or reduced to the form of a solution and heated, and the wood after having been
first thoroughly dried in a kiln or in any suitable manner is immersed in said
solution, and the said solution is preferably retained in a heated condition, and
the wood remains therein until it is thoroughly saturated or soaked with the
solution and sinks to the bottom thereof, after which it is taken out and dried for
use.
If a fabric, lace or similar article is to be treated, it is simply immersed in the
solution and taken therefrom and dried.
If the composition is used in connection with celluloid, it is placed in the
material of which the celluloid is composed when the latter is made, the composi-
tion being dry or in the form of a powder, and constituting about one-quarter
in weight of the substance from which the celluloid is made.
In addition to the foregoing ingredients, I may, in some cases, with great
advantage employ or add to said composition, one part of borate of sodium or one
part of borate of potassium, it being understood that either of these articles in
the proportions specified may be used in connection with the chloride of ammonia
and microcosmic salt herein before specified.
My improved composition is perfectly adapted to accomplish the result for
which it is intended, and is much cheaper in manufacture than any other article
of this class heretofore produced, and any article treated therewith is rendered
absolutely fire proof.
It will also be apparent that many other articles besides those herein before
named may be treated in a similar manner or for a similar purpose, and the
proportions of the parts specified may be slightly changed without materially
altering the character of the composition.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The herein described composition of matter consisting of chloride of ammonia
and microcosmic salt, substantially as described and for the purpose specified.
2. The herein described composition of matter, consisting of chloride of
ammonia, 15 parts, and microcosmic salt, 1 part, substantially as described and
for the purpose specified.
