Improvements in Water-proof Fabrics, Garments, Wrappers and
Coverings and in the Process and Composition for Manufactur-
ing the same.
We, EUGEN HORNUNG, Assistant Advocate, of XVIII, Weinerstrasse 76, and
RUDOLF LIEBL, Government Official, of XVIII, Herrengasse 70, both of Vienna,
in the Empire of Austria, 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:-
Our invention relates to water-proof fabrics, garments, wrappers and coverings
made by water-proofing paper or fabrics or paper strengthened by a fabric or a fibrous
material, and having when compared with materials obtained by the usual process of
coating or impregnating them with india rubber the advantage of being cheap, light
and odourless and of occupying but little space.
In order to adapt the paper or fabric for the said purpose, it is successively
covered with two coatings both of which can be are insoluble in water, or the-second
only may have that property, the first coating, in the latter ense, serving only for
filling the pores or openings of the rough material and for making it pliant.
Two-waterproof coatings are applied when it is desired to produce-materials-that
are to be continually exposed to moisture, or when-only-a single layer of paper-or
fabrio is treated. If, however, several layers-of-paper-or-fabric-are employed-laid
upon one another, or a layer of paper-strengthened by a fabric or by fibrous material,
the first conting may be non water proof. It is however obvious that, even in this
latter-ease, two water proof coatings-may-also-be-employed.
For the purpose of obtaining the first coating, glue (or a succedaneous substance,
such as dextrine, paste, etc.) is dissolved in water or other dissolving liquid, and-to
the solution is added The mass thus obtained is not insoluble in water. If it
should-be-desired 7'o make it so, the glue is precipitated from the solution by means
of a tannin solution or a substance having the same effect; the product thus obtained
is tough, and insoluble in water, and is then melted with the addition for the purpose
of pliability of glycerine, syrup, treacle, grease or oil, or a mixture of two or more of
these substances. The quantity of the additional matter or matters varies, (according
to the degree of pliability it is desired to impart to the rough material) between one
third and one half of the quantity of the solution of glue. one-or-of-several of the
aforesaid additional substances.
Tungstate of soda (NWO) may be added to the glue or succedaneous substance
in order to increase the toughness.
The mass thus prepared, which may be water-proof or not, and to which any
suitable colouring matter may be added, is applied in a coating of sufficient thickness
''

page_text: on the layers of paper or fabric, or the layers of paper or fabric are impregnated with
the said mass. In order to strengthen the material, a second layer may be pressed
or rolled on to the first layer, before the first coating is dry; or, two layers of paper
prepared in the aforesaid manner, may be pressed on to both sides of a fabric; or, the
layer of paper or fabric heing coated, loose fibrous material may be strewn on it, and
then covered by a second layer pressed on to it. The layers of fabric or fibrous material
may, before being used, be impregnated or covered with the same coating. Finally,
the material thus formed of several thicknesses may be covered externally on one or
both sides, with the said coating.
When dry, the material prepared in the aforesaid manner receives the second
coating, which in-all-enses must be water-proof, and consists of varnish or lacquer, to
which any colouring matter may be added at will and according to requirements.
When this second coating is dry, the layers of fabric or paper may be worked into
garments the several parts of which are united together either by sewing or by
cementing with a substance insoluble in water.
The finished material may also have any suitable pattern impressed therein.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. A process for manufacturing-water-proof materials, made of paper-or fabrics,
or of paper strengthened-by-a-fabric-or a fibrous substance,-which-process-consists
in-applying on the rough material-a-conting formed by mixing a solution of glue-(or
of-a succedaneous substance) with glycerine, syrup, trealee, grease-or-oil, then allowing
the paper or the fabric thus-coated to dry, superposing whenever-desired-before-they
get dry, several layers of paper or fabric covered with the said coating and finally
applying a conting of varnish or lacquer, substantially-as-herein before-described.
1.2. For manufacturing waterproof materials made of paper or fabrics or of paper
strengthened by a fabric or a fibrous substance the use as a first coating to be applied
on the rough material of enrrying-out-the-process-described-in-the-first-claim,- a com-
position, used-as-first coating, consisting of a mixture of glue. (separated in an
insoluble state, by precipitation, from a solution of glue or of a succedaneous matter)
with glycerine, syrup, treacle, grease or oil, substantially as herein before described.
3. Waterproof-materials obtained by the process--described in the first-cluim,-sub
stantially-us-described.
2. 4.-Water-proof materials obtained by the process for manufacturing waterproof
materials made of paper or fabrics or of paper strengthened by a fabric or a fibrous
substance chich process consists in applying on the rough material described-in-the-first
elnim,-use being made, as a first coating, of the composition described in the first
second claim, then allowing the paper or the fabric thus coated to dry, superposing
whenever desired before they get dry several layers of paper or fabric covered with the
suid coating and finally applying a coating of varnish or lacquer, substantially as
herein before described.
3. 5.-Garments, wrappers, coverings, etc. made of the water-proof materials described
in the second third and fourth claims, substantially as described.
