Improvements in Waterproof Garments, and a Process for
Manufacturing the same.
We, EUGEN HORNUNG, of XVIII Weinerstrasse 76, and RUDOLF LIEBL, of
Kirchenplatz 3, both in Vienna, in the Empire of Austria, Clerks, 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 waterproof garments and to a process for manufacturing
the same.
Waterproof garments hitherto in use, such as rain-mantles, collars, hoods, etc.,
are made of rubber-fabric, and in addition to the defect of being very expensive,
they are heavy, cumbersome and retain for a long time an offensive smell.
According to our invention we produce such garments free of all these defects,
by manufacturing them from paper rendered impervious to water, instead of from
rubber-fabric. The various parts forming the garments are fastened together by
sewing or by means of cement.
In order to obtain paper answering the required purpose with regard to toughness,
imperviousness and pliability, successive coatings are laid on the surface of
paper bands, the first layer being formed of a mixture of glue and glycerine,
or of glue and oil-varnish, in order to make the paper tough and pliant, and the
second layer consisting of varnish that makes it impervious to water.
The method employed is the following:-
:-
Four parts by weight of glue are dissolved in hot water or other liquid capable
of dissolving glue, and three to four parts by weight of glycerine are added to
it. The proportions of this mixture will vary within certain limits according to
the quality of the materials made use of, the said mixture having to fulfil the
condition of remaining pliant and elastic after it becomes cool. Provided this
requirement is answered, any agglutinating material may be employed, by itself or
in combination with glue, and oil-varnish may be taken as a partial or total sub-
stitute for glycerine.
Whilst the mixture is still hot and liquid, lamp black or other colouring
material may be added to it, according to the colour it is desired the garment
should have when finished.
.
The mixture thus obtained, while in a state of suitable consistency and if
possible while still hot, is laid on over the breadths of paper, either by hand or by
machinery after which the paper is allowed to dry.
:
The second layer consists of a semi-fluid paste of linseed-oil varnish or of strong
oil varnish, and of lamp black; oil- or alcohol-varnish, or lac mixed with the
colouring material may be used as substitutes for the linseed-oil-varnish, although
the result is not so good as regards the quality of the product. This second
layer is preferably applied in a cold condition when, after being once more allowed
to dry, the paper is ready for use.
Garments made of paper rendered impervious to water in the aforesaid manner
have about the same toughness as ordinary thin cotton fabrics, but naturally
cannot compare in this respect with rubber-fabrics. Their low cost however will
allow of new ones being frequently bought and of persons being amply provided
with pliant, light and uncumbersome garments, without the expenses thus incurred
although often repeated, amounting in one year to more than a fraction of the cost
of buying a single garment made of rubber fabric,

page_text: 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. Waterproof mantles, collars, hoods and other garments made of paper
rendered impervious to water, substantially. as hereinbefore described.
2. The herein described process for making paper tough, pliant and impervious
to water, such process consisting in covering the paper with two successive coats,
the first of which is a mixture of glue (or of other agglutinating material) and
glycerine or oil-varnish, with or without the addition of colouring materials and
the second a mixture of linseed-oil varnish (or of oil or alcohol-varnish) and of
colouring material.
