I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co, Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for IMPROVEMENTS IN MATERIALS FOR COVERING WALLS AND
CEILINGS, PACKING GLASS-WARE OR THE LIKE, AND FOR SIMILAR PURPOSES and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
:-
This invention has for its object to provide a cheap and durable embossed
material which can be successfully employed for the decoration of interior walls
and ceilings of buildings, or used as a carpet lining, or as an elastic packing for
glass ware crockery & and for other purposes.
The said invention comprises a sheet or roll composed of "chemical wood fibre"
having a raised design, or a series of cavities embossed therein; said material being
especially adapted for the purpose on account of the elasticity, strength, and
toughness of the fibres, which, when stretched in the embossing process, will
permanently retain the form imparted thereto and offer the maximum resistance to
any pressure or tendency of the raised surface to resume its original flat condition.
In the accompanying drawing
Figure 1 is a plan of a piece of the improved embossed material.
Figure 2 is a vertical section of the same.
Figure 3 is a similar section illustrating a method of imparting additional strength
and stiffness to the material.

A represents a sheet or piece of the improved material, which may be of any
suitable size and is composed of what is commonly known as
" chemical wood fibre
which is produced in any well known manner, as for instance by boiling wood in
the form of chips in vacuo with a strong solution of caustic soda or other suitable
Price 6d1

page_text: substance in order to eliminate all the amylaceous, glutinous, and siliceous matters
therefrom and leave the fibres of the wood in a comparatively pure state.
In carrying my invention into practice I take a sheet or roll of the "chemical
wood fibre" above described of the desired thickness, and produce thereon while
wet or damp, any desired raised design or pattern by means of suitable embossing
rolls or dies, after which it is allowed to dry, and if it is to be used as a covering
for walls or ceilings it may then be colored or bronzed if desired, or the material
may be colored in the pulp if preferred.
When the material is to be placed under carpets to diminish the wear and render
the same more elastic to the tread, I emboss the said sheet with a series of cavities a,
preferably circular, in horizontal section, and nearly hemispherical in vertical section.
I do not however confine myself to cavities of this particular form as other shapes
may be produced if preferred, the object being to form a cavity a on one side of
the sheet and a corresponding protuberance b on the opposite side of the same by
stretching the fibres of which the material is composed.
As the operation of embossing is performed while the material is wet or damp,
the fibres, when stretched, are not liable to become broken, and when dry will
permanently retain their form. Each cavity presents in vertical section the form of
an arch, the support of the arch being the remaining plain surface of the material,
so that any pressure, as by the foot, when the lining is in use, downward upon the
arch will merely bend the fibres momentarily, but cannot restore them to their
original straight condition, and consequently the elasticity of the material continues
unimpaired until it is worn out.
The "chemical wood fibre" above described I have found especially adapted for
the uses and purposes referred to, as the elasticity of the fibre permits it to be very
deeply embossed without liability of being broken as it is stretched, thus enabling
designs to be successfully produced in high relief with a smooth unbroken surface,
while after being stretched in the embossing process, the strength and toughness of
the fibres will cause the projections to permanently retain their form and offer the
maximum resistance to any pressure or tendency of the raised surface to resume
its original flat condition.
If desired, additional strength and stiffness can be imparted to the material by
treating it with glue and glycerine or other suitable liquid composition which, when
dry, will render the material elastic and at the same time increase its strength.
One method of applying the stiffening substance is illustrated in Figure 3 in
which the sheet A is formed of two thin sheets c, d, of the "chemical fibre" united
by an interposed layer e of glue, size, or analogous adhesive substance and then
cimbossed while the glue or adhesive substance is still damp. In this manner, when
the glue becomes hardened in drying, great additional stiffness and strength are
imparted to the projecting portions of the raised design, and it will be seen that by
introducing the glue.or stiffening substance between the two sheets, it is prevented
from coming into contact with, and clogging, the embossing rolls or dies, as would
be the case if it were applied as a coating to the outer surface of the material, while
the raised figures or projections are left clean and smooth as desired. I do not
however wish to confine myself to the employment of any additional stiffening
chemical fibre" render it well
substance as the peculiar characteristics of the
adapted for use when made of a single thickness only without additional stiffening,
as seen in Figure 2.
"
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
First. The herein described material for covering walls, lining carpets, packing
glass-ware, &, the same consisting of a sheet composed of "chemical wood fibre
having on ambooood surface substantially as set forth.

Second. A material for covering walls, lining carpets, &, composed of two sheets
of chemical wood fibre " united by an interposed layer of glue or analogous
adhesive substance, and then embossed before the said glue or adhesive substance
becomes dry, substantially as described.
