ALEXANDER MELVILLE CLARK, of Chancery Lane, in the County of Middlesex,
Patent Agent. "IMPROVED COMPOSITIONS FOR RENDERING TEXTILE FABRICS,
5 PAPER, AND OTHER MATERIALS UNINFLAMMABLE." [A communication from abroad
by Abel Jean Martin and Eugène Tessier, both of Paris, France.]
This Invention relates to improved compositions for rendering incombustible all
kinds of readily inflammable substances, such as woven and other fabrics of cotton
and other fibrous materials, paper, including bills of exchange and other securities,
woodwork, theatrical scenery, straw, &c.
The first composition, which may be applied to all kinds of fabrics without
deteriorating them in any way, consists of,-
Sulphate of ammonia (pure)
Carbonate of ammonia
Boracic acid
Borax (pure)
Starch
Water (distilled or other)

kilos.

It is simply necessary to steep the fabrics in a hot solution of the above compo-
sition until they have become thoroughly soaked, after which they are dried and
ironed or pressed like ordinary goods.
A 2nd composition, to be used for theatrical scenery (or the canvas to be used
for this purpose) and also for woodwork, furniture, door and window frames, &c.,
is to be applied hot with a brush like ordinary paint. It is composed of,—
Boracic acid
-
Hydrochlorate of ammonia or sal aminoniac
-
5

kilos.

page_text: A 3rd composition, to be used for coarse canvas or sail cloth, cordage, straw, and
wood, is applied by immersing the articles therein, and consists of,-
Boracic acid
Hydrochlorate of ammonia or sal ammoniac
Borax (pure)
Water (undistilled)

The solution is to be placed in a vat heated to 50° C. at the end of the paper
making machine, and the paper is to be passed through so as to be completely im-
pregnated, after which it is dried upon a warm cylinder and then wound on a reel.
If the paper be in sheets or printed on it is simply immersed in the above solution,
heated to 50° C., spread out to dry, and afterwards pressed to restore the glaze
destroyed by the solution.
The proportions of the several ingredients herein specified are given as examples
only, and may be varied as found necessary in practice.

"IMPROVED COMPOSITIONS FOR RENDERING TEXTILE FABRICS,
PAPER, AND OTHER MATERIALS UNINFLAMMABLE" A communication from abroad
by Abel Jean Martin and Eugène Tessier, both of Paris, France.
This Invention relates to improved compositions of an inexpensive nature for
rendering incombustible all kinds of readily inflammable substances, such as woven
O and other fabrics of cotton and other fibrous materials, paper, printed or otherwise,
including bills of exchange and other securities, woodwork, theatrical scenery,
straw, &c., the said compositions to be named A. Baudin's fireproofing.
The first composition, which may be applied to all kinds of fabrics without
deteriorating them in any way, consists of,-
Sulphate of ammonia (pure)
Carbonate of ammonia
Boracic acid
Borax (pure)
Starch

It is simply necessary to steep the fabrics in a hot solution composed as above
until they have become thoroughly impregnated, after which they are drained and
dried sufficiently to enable them to be ironed or pressed like ordinary starched
5 goods.
A second composition, to be used for theatrical scenery (or the mounted but un-
painted canvas to be used for this purpose) and also for woodwork, furniture, door
and window frames, &c., is to be applied hot with a brush like ordinary paint. It
is composed of,—

page_text: The solution is to be placed in a vat heated to 50° C. at the end of the paper
making machine, and the paper as it leaves the machine is passed through the
solution in this vat, so as to be completely impregnated therewith, after which
it is dried upon a warm cylinder and then wound on a reel. If the paper be in
sheets or printed it is simply immersed in the above solution, heated to 50° C.,
spread out to dry, and afterwards pressed to restore the glaze destroyed by the
moisture.
The above compositions ensure a degree of incombustibility without precedent
as regards the preservation of the materials to which they are applied.
The proportions of the several ingredients herein specified are given as examples
only, and may be varied as found necessary in practice.
Having described the nature of the Invention, and the manner of performing the
same, I declare that what I claim as the Invention to be protected by the herein-
before in part recited Letters Patent is,―
The several compositions, substantially as and for the purpose herein specified.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Ninth day of July, in the year of our Lord
One thousand eight hundred and seventy nine.
