Improvements in the Manufacture of Rubber Compounds and Fabrics.
We FREDERICK HENRY SMITH of Cambridge Street, Manchester, Director of
Messrs. Chas. Macintosh & Company, Limited, and CHAS. MACINTOSH & COMPANY,
LIMITED, of Cambridge Street, Manchester, Indiarubber Manufacturers, do hereby
declare the nature of this invention to be as follows:-
Our said invention has for its object the manufacture of new compositions or
fabrics containing indiarubber.
According to the first part of our said invention we incorporate with rubber or
with rubber and other suitable ingredients cellulose in a finely comminuted form
as a pulp or in any other convenient manner. After thorough incorporation the
mass is rolled, pressed, moulded or otherwise fashioned into any desired form.
According to the second part of our inveniton we make a compound fabric by
the use in combination with cloth and indiarubber of cellulose with or without
other additions. This compound fabric is produced by applying to the cloth
indiarubber and cellulose either by impregnation by spreading by the superposition
of separate layers or otherwise.
Our said invention is more particularly applicable to the form of cellulose known
in commerce as "Viscos" or "Viscose" which we prefer to subject to a washing
or purifying process in order to remove or neutralise deleterious by-products.
Compositions or fabrics made in accordance with our said invention are subjected
to vulcanisation or other treatment such as is usual in the manufacture of rubber
articles.

Improvements in the Manufacture of Rubber Compounds and Fabrics.
We, FREDERICK HENRY SMITH of Cambridge Street, Manchester, Director of
Messrs. Chas. Macintosh & Company, Limited, and CHAS. MACINTOSH & COMPANY,
LIMITED, of Cambridge Street, Manchester, Indiarubber Manufacturers, 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:-
Our said invention has for its object the manufacture of new compositions or

page_text: According to one part of our said invention we incorporate with rubber (or the
usual compounds of rubber combined with other commonly used materials)
cellulose either in a finely comminuted form, as a pulp or in any other convenient
manner. The quantity to be added may vary within very wide limits according
to the particular purpose for which the composition may be intended.
According to this part of our said invention the cellulose is intimately mixed with
the rubber in the usual manner of making rubber mixtures and after thorough
incorporation the mass may be rolled pressed moulded or otherwise fashioned
into any desired form.
According to the second part of our said invention we make a compound fabric
by the use in combination with cloth and india-rubber of cellulose with or without
other additions. According to this part of our said invention the cellulose is not
employed merely as a facing but enters into and forms an integral part of the
compound fabric. According to this part of our said invention we apply to the
cloth india-rubber and cellulose. This may be done by spreading on the cloth
a compound of rubber and cellulose, such as described under the first part of our
said invention. Or the cloth may be first impregnated or treated with cellulose
and a layer of rubber or rubber and cellulose may be applied thereto. Or the
cellulose may be spread as a coating or layer on a plain or rubber treated cloth
and be covered with another laver of rubber or rubber treated cloth. The means
for spreading and combining the layers may be those which are at present in
use in the manufacture of indiarubber waterproof fabrics and will be understood
without further description.
Our said invention is more particularly applicable to the forms of cellulose
known in commerce as "Viscos" or "Viscose "or made in accordance with Patent
No. 8700 of A.D. 1892.
We however make no claim to the manufacture or treatment of such forms of
cellulose except in so far as it forms a convenient form of cellulose for use in
carrving into practice our said invention.
We are aware that waterproofed cloths have been treated on the face with
cellulose in order to produce a surface for the recention of ornamentation but
such use of cellulose is outside the scope of our said invention and we make no
claim thereto.
Compositions or fabrics made in accordance with our said invention are sub-
jected to vulcanisation or other treatment such as is usual in the manufacture of
rubber articles.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:—
1. A composition produced by the intimate mixture or incorporation of cellulose
with rubber or rubber compounds substantially as set forth.
2. A new fabric consisting of cloth combined with rubber and cellulose
substantially as set forth.
