Improvements in Means for Preventing the Flooding of Ships and
other Vessels.
I, OTTO HÖLTKEN, of 73, Vorwerkstrasse, Breslau, Prussia, Distiller, 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 means for preventing the flooding of ships and other
vessels in the case of leakage of the ship's hull through collision or other cause.
According to this invention a protective lining of waterproof material is
applied to the inside surface of the hull of the ship or the like in such a manner
that, in the case of the ship springing a leak, the protective lining will prevent the
water from flooding the ship's hold.
In the accompanying drawings,-
Figures 1, 2 and 3 illustrate diagrammatically the mode of application of the
protective lining to the interior of the ship's hull. a represents the protective
lining and b the hull.
Figures 4, 5, 6 and 7 illustrate the mode of application moro in detail.
Figure 8 illustrates diagrammatically the mode of operation of the protective
lining in the case of a hole having been knocked into the ship's side, and
Figure 9 is a section of a suitable form of the material of the protective lining:
Only those parts of the ship's hull which come in contact with the water neeil
to be provided with the covering.
The protective lining may be made of any suitable waterproof material d; and
it is provided for strengthening purposes on one or it may be on both faces with
a wire backing or covering e (Figure 9).
The mode of attachment of the protective lining is illustrated in Figures 4 to 7.
These figures show the covering arranged in horizontal folds or in vertical folds
as may be desired.
The lining may be hidden from view and kept in place by any suitable means,
preferably by means of thin match boarding as indicated at f
A waterproof, but not too strong, attachment of the lining of the ship's hull
must be provided at suitable distances apart (as at g in Figures 4 and 5), so that in
case of the ship's side being burst in or penetrated at any spot, the lining will
bulge out inwardly only up to the points of attachment g (Figure 8) which are
situated nearest to the said spot, and by so bulging out inwardly will prevent the
inrushing water from flooding the ship.
At those places where a transverse or a horizontal partition meets the inside
wall of the hull; the lining is not attached in the angle of the two walls, but is
carried some distance along the partition and there fastened to the hull (see
Figure 6). In the angle the lining is attached only by means of a suitable form
of clip h which is adapted to be opened without difficulty.

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:-
A protective lining for ships and the like, consisting of a suitable waterproof
material arranged in folds and attached in a suitable manner to the inside of the
ship's hull as a means of preventing flooding of the ship from the outside, con-
structed arranged, and operating substantially as described and shown.
Dated this 4th day of July 1899.
