Improvements in the Manufacture of Material suitable for Belting,
Carding Cloths, Soles of Boots, and like Uses.
I, FREDERICK WEAVER OLIVER of 40 King Street, Cheapside in the City
of London, Lithographer, do hereby declare the nature of this invention to be as
follows:-
According to this invention I manufacture a material suitable for belting, carding
cloths, soles of boots, and like uses by uniting two or more layers of a material
which has been impregnated with liquid celluloid.
Two or more layers of the material impregnated with liquid celluloid may be
pressed together and made to adhere before they are dry or if the impregnated
materials have already dried the surfaces may be softened by a solvent of celluloid
and then pressed together.
In this manner a thick waterproof material is formed with a very durable surface
and one which will also withstand the actions of acids.
The materials which may be used are very various and include materials such
as cotton duck, jute cloth or other woven fabric or leather &c.
In the manufacture of belting the material may be cut into strips the required
width and a suitable number are cemented together in the manner before described.
A strip slightly wider than double the width of these being folded over and
cemented to them with its two edges meeting in the middle of the face which is
intended to be the inner face of the belt. The belt may also be strengthened by
being stitched and the holes and thread may be covered with liquid celluloid in
order that the latter may be protected from damp &c.
For carding cloths, soles of boots and like uses the material may either be cut
into the required shapes before the separate layers are ceinented together or it
may be made iu sheets and cut to the required shapes after cementing.
Dated this 11th day of May 1896.

Improvements in the Manufacture of Material suitable for Belting,
Carding Cloths, Soles of Boots, and like Uses.
I, FREDERICK WEAVER OLIVER, of 40 King Street, Cheapside, in the City
of London, Lithographer, 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 :-
According to this invention I manufacture a material suitable for belting,
carding cloths, soles of boots, and like uses by uniting two or more layers of a
material which has been impregnated with liquid celluloid, or nitro cellulose
dissolved by the aid of camphor in a spirituous solvent.
Two or more layers of the material impregnated with liquid celluloid may be

page_text: pressed together and made to adhere before they are dry or if the impregnated
materials have already dried the surfaces may be softened by a solvent of celluloid
and then pressed together.
In this manner a thick waterproof material is formed with a very durable surface
and one which will also withstand the actions of acids.
The materials which may be used are very various and include materials such as
cotton duck, jute cloth or other woven fabric or leather &c.
Thus I can make packing for glands and other joints of asbestos impregnated
with liquid celluloid. Preferably in the case of rollel packings the asbestos is in
the form of a woven fabric cut on the bias and rolled upon itself or on a core,
in a similar manner to the combined asbestos and rubber packings, now in use.
In rolling up each fold, I cement it to the fold beneath by means of liquid
celluloid.
In the manufacture of belting the material may be cut into strips the required
width and a suitable number are cemented together in the manner before described,
a strip slightly wider than double the width of these being folded over and cemented
to them with its two edges meeting in the middle of the face which is inten led to
be the inner face of the belt. The belt may also be strengthened by being stitched
and the holes and thread may be covered with liquid celluloid in order that the
latter may be protected from damp, &c.
For carding cloths, soles of boots an like uses the material may either be cut
into the required shapes before the separate layers are cemented together or it
may be made in sheets and cut to the required shapes after cementing.
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. A material consisting of two or more layers of woven fabric saturated with
liquid celluloid superposed one on another and united by celluloid serving as a
cementing medium.
2. A packing for joints made in accordance with Claim 1.
3. Belting consisting of strips of woven fabric saturated with liquil celluloid
and enveloped in a wrapper similarly saturated, the whole united by celluloid
serving as a cementing medium.
4. Packing for joints consisting of asbestos fabric saturated with liqui celluloid,
accumulated layer upon layer and united by celluloid serving as a cementing
medium.
