Improvements in the Production of Ornamental Effects on India
Rubber Coated Fabrics and in the Means or Apparatus Employed
therein.
I, THEODORE BIRNBAUM of Wick Lane Rubber Works, Bow in the County of
Middlesex, India Rubber Manufacturer, do hereby declare the nature of this in-
vention to be as follows:-
I spread the fabric as usual, the last coating of rubber applied when spreading
being tinted to any desired colour or shade. I take the spread fabric and cause
the tinted surface to pass to or over a series of rollers revolving parallel to one
another in troughs containing a solution of naptha and aniline or other suitable
oil dyes soluble in Nuptha. These rollers are cut in regular patterns and are so
arranged that their printing surfaces may be accurately adjusted in relation to
one another so as to form a required design. I thus effect the printing of coloured
designs on rubber fabrics without the intervention of any fixative substance such
as farina or fibre the printing being applied directly to the rubber surface. The
coloured naptha is absorbed well into the body of the uncured rubber fabric and
causes it to be patterned throughout its entire thickness so that the design will
not be affected or effaced by wear. Such printing does not add to the weight
of the fabric-nor does the print require fastening as with methods now in vogue
-by running a transparent coating of pure rubber over the printed surface before
curing.
When the colourings have been applied to the rubber surface, as described
herein the goods are farinad or otherwise finished and cured by any of the well
known methods of curing and finishing.

Improvements in the Production of Ornamental Effects on India
Rubber Coated Fabrics and in the Means or Apparatus Employed
therein.
I THEODORE BIRNBAUM of Wick Lane Rubber Works, Bow in the County of
Middlesex, India Rubber Manufacturer, do hereby declare the nature of this in-

page_text: vention 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 reference to the production of ornamental effects on india
rubber coated fabrics, amongst others, of the character of pattern or design
described in the Specification of Letters Patent granted to me dated January
the 10th 1894 and numbered 561 but instead of producing the modifications of
the stripings or streaks by means of a moving oscillating or other comb or gauge
or part adapted to act on the stripings, or streaks as first laid on the rubber
surface, I according to my present invention proceed as follows:-that is to say-
I spread the dough, or coat the fabric with coatings of rubber, as usually
performed in the trade, the last coating of rubber when spreading being tinted
to any desired colour, or shade. I then take the spread fabric and cause the
tinted surface thereof to pass to and over a series of rollers revolving parallel to
one another in troughs, or vessels, containing a solution of naptha and aniline,
or other suitable oil dyes soluble in naptha. These rollers are cut in regular
patterns and are so arranged that their printing surfaces can be accurately adjusted
in relation to one another so as to form a desired design. Or, alternatively I
cause the designs engraved upon the rollers to be so arranged that by the inter-
section of printed lines a synimetrical watered effect is obtainable. This can be
done either by causing the one set of lines on the one roller to be waved and those
on the co-operating roller to be straight lines, or, I cause the fabric in its passage
from one roller to the other to be oscillated in a lateral direction by means of an
oscillating bar, or connection operated by a cam or other suitable equivalent device
whereby the desired intersection of these lines and the consequent watered effect
is attained (see Fig. 7).
I am thus enabled to effect the printing or production of coloured designs, or
patterned surfaces, on rubber fabrics without the intervention of any fixative sub-
stance such as farina or fibre, the printing being applied directly to the rubber
surface. By the improved method, herein described, the permenting or penetrating
naptha is absorbed well into the substance or body of the uncured rubber fabric
and causes it to receive the design or pattern throughout its entire thickness so
that the design or pattern will not be affected, or effaced with wear.
Such printing does not add to the weight of the fabric, nor does the printed
design or pattern require to be fixed, or fastened as is necessary with methods
now generally employed-that is to say, by running a transparent fixing coating
of pure rubber solution over the printed surface before curing.
When the coloured designs or patterned surfaces have been applied to the rubber
as hereinbefore described the goods are farinad, or otherwise finished and cured
by any of the well known methods of curing and finishing employed for this
purpose.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews to a reduced scale a side view partly in section and Fig. 2
shews a partial sectional view of an arrangement of rollers and troughs with
supporting and adjusting mechanism.
Figs. 3 and 3 shew an enlarged plan of parts indicated by Figure 1 divided
on the line B B for convenience of the drawing.
Fig. 4 shews a modification of the form of the roller for printing the super-
imposed design the ridges or printing surfaces being serpentine.
l'igs. 5 and 6 shew details indicating the relative planes of the printing surfaces.
Figs. 7 and 8 shew details of the effects (amongst others) that can be produced
by the aid of the present apparatus.
a indicates the sheet of fabric, rubber coated, being printed. This sheet passes
in the direction of the arrows over and in printing contact with the roller b
which roller is supported in bearings band so as to receive solution of colouring
matter from the trough c. Thence the fabric passes over the roller d and under

page_text: the jockey roller e to the second printing roller f where it receives the super-
imposed impression and thence it passes to the drum g after printing.
By the raising, or lowering of the jockey roller e by the movement vertically of
its bearings e', (one of which only is shewn) the fabric is pressed down into print-
ing contact with the printing rolls b and f, or is released therefrom. The springs e
serve to keep said bearings e' up, whilst the screws 3 and adjusting hand wheele
(one of each said parts only appearing) serve to depress them. The lifting of
the sheet of rubber fabric, or of the cloth attached thereto to prevent soiling by
the printing rollers when the desired impression has been completed is ensured
by the simultaneous raising of the roller carried in bearings actuated by the
same lifting parts as is the roller e. The raised position of the sheet is indicated
by the dotted lines, as also is the raised position of the rollers d and e.
"The lateral relative adjustment of the print rollers 6 and f is effected by means
of the set screws g and h, respectively borne in screwed bearings g', of the
brackets g, carried by the framing i. These screws g, h have on their ends
enlargements g, h³ which engage shoes g, mounted on the troughs c which
carry the bearings b', f of the 'rollers band f.
jis a guide roller to correctly guide the sheet a to the roller b.
k is a lever centred at & and rigidly connected to this lever is the arm A, which
arm is hinged to the vertical arm which is hinged to the bearing for the
axis of the roller d and serves to raise and lower it.
Although I have shewn the screw parts e³, e and spring as well as the lever
parts k, k³, 13, 13, the former may be dispensed with or vice versa, the lever arrange-
ment alone being capable of rapidly effecting the movement of the rollers.
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. The production of printed ornamental effects on india rubber coated fabrics
without the intervention of any fixative substance, such as farina, or fibre the
printing being applied directly to the rubber surface, substantially as set forth.
2. The method of producing striped, "watered," or other similar ornamental
effects on india rubber coated fabrics by coating the fabric in usual known manner,
using the last coating of rubber tinted to any desired shade, and then applying
to said coating, or surface a solution of aniline, or other suitable dye in naptha,
or equivalent solvent, by means of rollers having their printing surfaces so cut
and patterned as to co-operate to produce "watered" or equivalent lined effects,
directly onto the rubber surface, substantially as hereinbefore set forth.
3. The use for the production of printed ornamental effects by the application
of suitable colour and solvent of the character herein set forth, of intersecting
patterned or co-operating rollers, adapted to produce striped, "watered" or
equivalent lined effects, directly on to rubber surfaces, substantially as set forth.
4. The arrangement, or combination and use of parts of apparatus for the pro-
duction of printed ornamental effects on india rubber coated fabrics by means of
a suitable colour and solvent directly onto the rubber coating of a fabric, sub-
stantially as and for the purpose set forth.
