Improvements in the Treatment or Manufacture of Hosepipes, Casks,
and other like Articles to render them Tight.
I, FRANZ XAVER SERVATIUS, 1, Brandenburgstrasse, of Cologne on the Rhine,
in the Empire of Germany, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in the treatment or manufacture of hose-
pipes, casks and other like articles to render them tight for the conveyance or storage
of petroleum and like liquids or gases.
Indiarubber tubes have been mainly up to the present employed for this purpose.
These however last only a short time, as they are easily attacked by the substances
in question and dissolved. By the present invention the pipes, casks or like articles
which may be made of india-rubber, guttapercha, webbing, wire net, paper, wood
pulp or the like are saturated with glue, to which, in order to produce the right
degree of consistency, about 5% in weight of glycerine has been added. The
amount of glycerine added may be larger or smaller according to whether it is
desired to obtain a comparatively soft and flexible or a more tough hard consistency.
For a pipe which is intended to have a certain flexibility the above proportionate
quantities are suitable because by this means the preservative coating does not
crack or split. For a cask which is only subjected to little or no alteration of form
a very small or even no addition of glycerine is necessary.
In order by this invention to render pipes and the like articles resistant to dele-
terious influences, or in other words liquid tight, it is necessary to coat those surfaces
which directly or indirectly come in contact with the liquids or gases with as thick
a coat as possible of the compound of glue and glycerine. This takes place in most
cases by dipping the article into the mixture or by spreading the mixture on the
article. A hosepipe is preferably prepared by pouring the composition over the inner
surface. The inner surface of such a pipe may also be formed by rolling a fabric
of flax, asbestos or like fibres, metal wire, leather, wood pulp or paper saturated
with the above composition one or more times over itself. Or the pipe may be
formed of one or more networks of vegetable fibres or metallic wires, the threads or
meshes of which have been previously or subsequently saturated with the above
composition, and in this manner form a compact casing capable of resisting dele-
terious action.
Finally the pipes, casks or other like articles may be made by placing liquid
resisting substances between two networks or fabrics or by adding a suitable quantity
of the substance to the respective raw materials such as indiarubber, guttapercha,
ballata, paper wood pulp or other suitable fibrous or pulverulent substances.
In order to protect the tubes on the outside against the action of water or the like,
they may be covered with a coating of indiarubber, guttapercha, leather or fibrous
or metallic fabric or the like, or be smeared or coated with indiarubber solution,
varnish or the like. A wire may also be employed for internal stiffening or out-
wardly protecting such a pipe according to whether the same is to be employed as
a suction tube or as pressure hose.

page_text: Other articles, such as tanks, casks, tubes, flanged joints for mains and the like
may also be made in a similar way to hosepipes.

Improvements in the Treatment or Manufacture of Hosepipes, Casks,
and other like Articles to render them Tight..
I, FRANZ XAVER SERVATIUS, of 1, Brandenburgstrasse, Cologne-on-the-Rhine,
in the Empire of Germany, 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:-
This invention relates to improvements in the treatment or manufacture of hose-
pipes, casks and other like articles to render them tight for the conveyance or storage
of petroleum and like liquids or gases.
Indiarubber tubes have been mainly up to the present employed for this purpose.
These however last only a short time, as they are easily attacked by the substances
in question and dissolved. By the present invention, the pipes, casks or like articles
which may be made of india-rubber, guttapercha, webbing, wire net, paper, wood
pulp or the like are saturated with glue, to which, in order to produce the right
degree of consistency, about 5% in weight of glycerine has been added. The
amount of glycerine added may be larger or smaller according to whether it is
desired to obtain a comparatively soft and flexible or a more tough hard consistency.
For a pipe which is intended to have a certain flexibility the above proportionate
quantities are suitable because by this means the preservative coating does not
crack or split. For a cask which is only subjected to little or no alteration of form
a very small or even no addition of glycerine is necessary.
In order by this invention to render pipes and the like articles resistant to dele-
terious influences, or in other words liquid tight, it is necessary to coat those surfaces
which directly or indirectly come in contact with the liquids or gases with as thick
a coat as possible of the compound of glue and glycerine. This takes place in most
cases by dipping the article into the mixture or by spreading the mixture on the

they may be covered with a coating of indiarubber, guttapercha, leather or fibrous

may also be made in a similar way to hosepipes.
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. A method of making hosepipes, casks and other like articles for holding and
conveying petroleum, ether, sulphide of carbon, naphtha, coal oil and other like
liquid or gaseous bodies, consisting in rendering the hosepipes, casks, or the like,
resistant or impervious to the deleterious action of the said substances by treating
them with glue with or without the addition of glycerine, substantially as herein-
before set forth.
2. A hosepipe of indiarubber, guttapercha, canvas, wire netting, leather, or the
like, the surfaces of which pipe, which are exposed to the deleterious action of the
contents, are coated with a composition consisting of glue with a variable addition
of glycerine, or during the making of which the said composition is added to the
material of which the pipe is composed substantially as described.
