We RICHARD RUSSELL GUBBINS of 17 Park Road New Cross in the county of
Kent Gentleman and CHARLES KEIR FARQUHARSON of 34 Hereford-Square South
Kensington Gentleman do hereby declare the nature of our said invention for
IMPROVEMENTS IN MANUFACTURING AND WATERPROOFING ARTIFICIAL LEATHER, to
be as follows:
The first part of our invention relates to improvements in the manufacture of
the artificial leather or American leather or American cloth made by coating or
impregnating cloth with various gums or compositions and consists mainly of
using as the basis or foundation of the artificial leather a knitted fabric such as
stockinette instead of the woven cloths which have hitherto been employed for
this purpose.
This we either coat or impregnate with the desired gum or
composition in any well known manner. In many cases we find that the tubular
form in which stockinette leaves the knitting machine suitable for the object in
view, as in the case of Hose pipes. In others we open it out and stretch it before
we apply the gums or compositions.
The second part of our invention consists in the use of Euphorbia gum as a
means of water proofing the said stockinetto fabric or fabrics of various kinds
which may or may not have been treated with other compositions. For this
purpose we dissolve the gum with any suitable solvent and by means of brushes
or spreading devices carefully coat or impregnate the material which we wish to
waterproof or the article made therefrom; we add if desired any pigments needed
to give colour to the dissolved Euphorbia gum, which being exceedingly tenacious,
eleastic, and anhydrous thoroughly effects our object, when it is necessary that the
artificial leather shall be very pliable and perfectly tight against air or gases or
that its surface is to be embossed in imitation of the grain of leather or with any
desired design we coat the knitted fabric or stockinette with a mixture of glue and
glycerine which we then treat with a solution of bichromate of potash in a way
well known to manufacturers. When thoroughly dry we coat the surface with the
solution of Euphorbia gum and when this is sufficiently dry we pass it through

page_text: embossing rollers in the usual way if required and may use any knitted m
instead of the stockinette.. An excellent material for driving bands may be
of stockinette stretched and thoroughly saturated with Euphorbia gum solut
which burnt umber and yellow ochre can be added to impart the colour of
to the solution and these will be found to be convenient pigments for this pu
Leather well suited for various manufacturing purposes such as bellows, ga
and so forth may be made in the same manner and will be found to wear al
not quite as well as real leather of good quality; a large variety of articles 1
made of suitable textile fabrics and they may be rendered waterproof by a
the Euphorbia gum solution.
The articles set out in the following list may be made of this improved a
leather.
Air cushions.
Foot balls.
Collapsible boats.
Gas bags.

Leather and in. the Manufacture of Driving Bands therefrom.
We RICHARD RUSSELL GUBBINS of 17 Park Road New Cross in the county of
Kent Gentleman and CHARLES KEIR FARQUHARSON of 34 Hereford Square South
Kensington in the county of Middlesex Gentleman do hereby declare the nature
of our invention for IMPROVEMENTS IN MANUFACTURING AND WATERPROOFING
ARTIFICIAL LEATHER and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The first part of this invention relates to improvements in the manufacture of
the artificial leather or so-called 'American cloth made by coating or impregnating
cloth with various gums or compositions and consists mainly in using as the basis
or foundation of the artificial leather a knitted fabric such as for instance
stockinette instead of the woven cloths which have hitherto been employed for
this purpose.
This knitted fabric is either coated or impregnated with the desired gum or
composition in any well known manner. In many cases it is found that the
tubular form in which stockinette leaves the knitting machine is suitable for
the object in view, as for instance in the case of hose pipes. In other cases the
stockinette is opened out and stretched before the gums or compositions are
applied.
The second part of this invention consists in the use of Euphorbia gum as a
means of waterproofing the said knitted or stockinette fabrics of various kinds
which may or may not have been treated with other compositions. For this
purpose the Euphorbia gum is dissolved with any suitable solvent and by means
of brushes or spreading devices the material-which is wished to be waterproofed-
is carefully coated or impregnated or the article made from the material is so
treated.
There is to be added to the dissolved Euphorbia gum any pigments needed to
give color thereto, and the said gum being exceedingly tenacious, eleastic and,
anhydrous thoroughly effects the object' desired.
When it is necessary that the artificial leather shall be very pliable and perfectly.
tight against air or gases or that its surface is to be embossed in imitation of the
grain of leather or with any desired design, we coat the knitted fabric or stockinette
with a mixture of glue and glycerine which we then treat with a solution of
bichromate of potash in a way well known to manufacturers and when thoroughly
dry we cont the surface with the solution of Euphorbia gum and when this is
sufficiently dry we pass it through embossing rollers in the usual way if required.
Or we use a solution of gutta-percha for this purpose in which case the Euphorbia
solution may be dispensed with and it is to be noticed that this artificial leather is
not to be elastic.
