Improvements in the Manufacture and Production of a Material'
suitable for Impermeable Partitions, Coverings, Roofs, Walls,
Floors, or other Surfaces, and for other purposes, such as for
Making Tanks or Vessels, Covering Pipes, and the like.
I ARTHUR SIEBEL of Düsseldorf in the Kingdom of Prussia, German Empire,
Wehrhahn No. 27 also Oststrasse. 2, Manufacturer of Building Materials do hereby
declare the nature of my invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
My invention has reference to the manufacture and production of a material
suitable for use for impermeable partitions for covering roofs, walls, floors and
surfaces of all kinds and for making vessels tanks reservoirs jacketings for pipes or
for other analogous purposes.
The material may also if required to be non-corrodable.
The said material is made of a combination of thin leaves or sheets of metal
such as lead for example. In order to detect flaws in the thin metal employed the
process of combining the sheets or leaves can be most efficiently carried on in a
dark chamber each sheet or leaf of metal being spread out flat upon a table of
transparent material such as glass lighted from below so that any hole or defect in
the sheets or leaves can be at once detected and made good with the blow-pipe.
As many as are required of the sheets or leaves which have thus been prepared as
are necessary to make up the required thickness are soldered together with the
blow-pipe at the edges and so plates or compound sheets of the required length and
breadth are produced. These plates or compound sheets are protected on one or
preferably on both sides by a layer of stiffening material for which purpose
tissues or fabrics of various kinds such as felt, paper, papier-mache or the
like may be employed. The tissue or fabric selected being impregnated with
tar, asphalt, pitch or similar substance or composition and being caused to
adhere to the metal leaves with or without the employment of pressure. Or
the strengthening may be effected by coating the plates or compound sheets
themselves with tar, asphalt, pitch or similar substance or composition. In
order to form plates or compound sheets of larger surface care is taken to make
the joints as tight as possible by covering the joints of the leaves with strips of oil
paper and then applying layers of strengthening material as described. The strips
of oil paper do not adhere either to the leaves or to the strengthening material so
that they may easily be withdrawn and if it be desired to connect a number of
such plates together the edges of the strengthening material are unfolded the paper
strips removed and the plates brought together in such a way that the edge of each
leaf of one plate is made to partly overlap a leaf of the adjacent plate and they
are then soldered together and the edge of the one piece of strengthening material
is then folded back over the line of junction and then the edge of the other piecę
of strengthening material is folded similarly so that it projects over the edge of
the other piece of strengthening material the two being then united with one
another by any suitable means such as cementing pressing or both.
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. The manufacture and production of a material for partitions or for covering
surfaces or for other purposes by the preparation and combination of thin metal
sheets or leaves substantially as hereinbefore described.

page_text: 2. The manufacture and production of a material for partitions or for covering
surfaces or for other purposes by the preparation and combination of thin metal
sheets or leaves into plates or compound sheets and the joining together of
several such plates or compound sheets at their edges substantially as hereinbefore
described.
