Improved Wall Coverings.
I, JOSEPH ALFRED FISHER, General Manager of the United Asbestos Company
Limited, of Dock House, Billiter Street, in the City of London, do hereby declare the
nature of this invention to be as follows:-
In many buildings, especially in large buildings trouble is experienced from the
reverberation of sound. I provide a wall covering which overcomes this difficulty
while at the same time it suitably decorates the surface to which it is applied.
I make my improved wall covering of asbestos a material which in consequence of
its porosity and its high specific gravity, is highly efficient in killing sound waves
which impinge upon it.
I make my improved wall coverings in the following manner :-I take a thick
coarsely woven soft asbestos fabric and I lay upon it a sheet of asbestos cardboard or
asbestos paper which has been lightly pasted on the surface. I place the two together
between a pair of pattern blocks and by hydraulic or other pressure I emboss the
material and at the same time obtain a firm adhesion.
Wall coverings thus produced have the further advantages that they are completely
fireproof and are not subject to change or decay. For the asbestos cardboard or
asbestos paper I might substitute other paper or cardboard but in so doing I should
sacrifice some of the advantages which my improved wall coverings present.

Improved Wall Coverings.
I, JOSEPH ALFRED FISHER, General Manager of the United Asbestos Company
Limited, of Dock House, Billiter Street, in the City of London 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 :—
In many buildings, especially in large buildings trouble is experienced from the
reverberation of sound. I provide a wall covering which overcomes this difficulty
while at the same time it suitably decorates the surface to which it is applied.
I make my improved wall covering of asbestos a material which in consequence of
its porosity and its high specific gravity, is highly efficient in killing sound waves
which impinge upon it.
I make my improved wall coverings in the following nanner :-I take a thick
coarsely woven soft asbestos fabric and I lay upon it a sheet of asbestos card board
or asbestos paper which has been lightly pasted on the surface. I place the two
together between a pair of pattern blocks and by hydraulic or other pressure I emboss
the material and at the same time obtain a firm adhesion.
Wall coverings thus produced have the further advantages that they are completely
fireproof and are not subject to change or decay. For the asbestos cardboard or
asbestos paper I might substitute other paper or cardboard but in so doing I should
sacrifice some of the advantages which my improved wall coverings present.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. Embossed wall coverings substantially as described, produced by combining a
woven fabric of asbestos with asbestos paper or cardboard by the aid of paste and
exposure together to heavy pressure with pattern blocks as herein set forth.
2. Embossed wall coverings substantially as described and produced as set forth
in the preceding claim but with paper or cardboard other than asbestos paper or
cardboard.
