⚫I, HERBERT JOHN ALLISON, of 52 Chancery Lane, London, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention which
has been communicated to me from abroad by Robert Florent Nenninger, of
Newark, New Jersey, United States of America, Engineer, and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:-
My invention relates to a material capable of many useful applications such as
for floor and wall covering as a substitute for leather or cork and for other
purposes to which an elastic tough flexible water proof body may be adapted.
The said material consists of any fiber preferably short, such as that of linen cotton
or jute as prepared for example in pulp for paper making mineral or animal wool
any felting material such as hair or fur and so on through a great variety of
substances, animal, vegetable or mineral. With the said fiber I combine any
suitable water proof resinous or gummy substance which can be dissolved in a
volatile fluid such as a light hydrocarbon, which hydrocarbon I subsequently cause
The fiber is then agglutinated by
to evaporate and so be expelled from the mass.
the gummy substance and on drying there is produced a strong elastic flexible
body which may be pressed, if desired into any suitable form. Thus for example
I may use as fiber paper pulp in a dry state and as the permeating liquid the
gummy or resinous residue produced by heating linseed oil to a high temperature,
this residue being dissolved in a suitable hydrocarbon which hydrocarbon is
subsequently expelled from the mass by volatilization. The resulting body may
be pressed into shape-as for example by passage between rollers to form a flexible
sheet.
In conducting this manufacture I prefer to use the following process-The fiber
selected being first cleansed if necessary, is brought into some aggregate form.
Thus for example in using paper pulp I allow the same to be deposited from the
slip upon the screen in the usual way and thence to pass to the felted rollers.

page_text: When the pulp is dry but before it is pressed or calendared I take it from the
rollers in suitable lengths. It is then of loose fibrous texture and bibulous so that
any thin liquid will readily penetrate throughout its mass.
I prefer to use naptha as the light hydrocarbon in which the water proofing
material is dissolved-producing a thin fluid which I apply to the fibrous body by
which it is at once absorbed and apparently all of the fibers become coated with
the gun. My next step is to apply heat to the said body in any suitable way
until the hydrocarbon solution is volatilized and driven off. The viscous gum
remaining then agglutinates the fibers and there is produced a body having the
characteristics already noted. This body I compress between rollers into sheets or
press into any desired form.
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 process of manufacturing an elastic flexible body which consists in
molding or pressing any fibrous material into desired shape and drying the same,
then treating said material with a gummy or resinous water proof substance
dissolved in a volatile solvent and then evaporating said volatile solvent.
ቤ
Second. The composition' herein described consisting of a fibrous substance and
resinous or gummy water proof substance the said substances being intimately
mingled and agglutinated into an elastic flexible mass.
Third. The composition herein set forth consisting of paper pulp in a dry state
and the gummy viscous residue derived from heating linseed oil, the same being
intimately mingled and agglutinated into an elastic flexible mass.
