We GOODMAN CHARLES MANDLEBERG, HENRY LESSER ROTHBAND, and SAMUEL
LAWRENCE MANDLEBERG of the Albion Rubber Works, Pendleton, Manchester in
the County of Lancaster, Manufacturers of India Rubber, Piece and other Goods,
do hereby declare the nature of the said invention, to be as follows:-
Our invention relates to fabrics produced by coating cloth with india rubber
which is vulcanized by liquid solutions and immediately after, while the india
rubber surface is still tacky, has farina or other suitable powder applied thereto.
Such fabric is well known and is produced in the manner above described which is
an ordinary and well known process of manufacture.
Our invention consists in producing striped or ornamental designs or effects
while manufacturing farina or other powdered india rubber waterproof fabrics by
the ordinary process by fixing a comb or other equivalent instrument or means
across the fabric while being operated upon, so as to act upon the india rubber
surface after it has been vulcanized by the solution employed, and while it is yet
tacky, a little before or at the time or a little after the farina or other powder is
applied.
The points of the teeth of the comb or its equivalent which may have teeth of
any desired width and with any desired space between them touches and acts
upon the tacky vulcanized surface of the india rubber with the result that a
striped pattern or design or effect is produced on the fabric, which is thus
vulcanized, has the farina or powder applied to it, and is ornamented at one and
the same operation and in the same machine.

We GOODMAN CHARLES MANDLEBERG, HENRY LESSER ROTHBAND, and SAMUEL
LAWRENCE MANDLEBERG of the Albion Rubber Works Pendleton, Manchester, in
the County of Lancaster Manufacturers of India Rubber, Piece and other Goods 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 invention relates to fabrics produced by coating cloth with india rubber
which is vulcanized by liquid solutions and immediately after, while the india
rubber surface is still tacky, has farina or other suitable powder applied thereto.
Such fabric is well known and is produced in the manner above described which is
an ordinary and well known process of manufacture.
Our invention consists in producing striped or ornamental designs or effects
while manufacturing farina or other powdered india rubber waterproof fabrics by
the ordinary process, by fixing a comb or other equivalent instrument or means
across the fabric while being operated upon, so as to act upon the india rubber
surface after it has been vulcanized by the solution employed and while it is yet
tacky, a little before the farina or other powder is applied.
The points of the teeth of the comb or its equivalent which may have teeth of
any desired width and with any desired space between them touches and acts upon
the tacky vulcanized surface of the india rubber so as to disturb it but does not
remove from or add any material to the fabric, with the result that a striped
pattern or design or effect is produced on the fabric, which is thus vulcanized, has
the farina or powder applied to it, and is ornamented at one and the same
operation and in the same machine.
In carrying out our invention we use the ordinary machine for producing farina
coated india rubber waterproof fabrics in which after the india rubber proofing
bas been acted upon by the vulcanizing solution the cloth passes over an upper
roller, the proofed face upwards and before it arrives at the point where the farina
is applied we operate upon it by the comb or its equivalent which is or may be in
a vertical position and it is arranged to press upon the proofed and vulcanized face
of the cloth, the back of which passes over the upper surface of two bars passing
across the machine, that is over one bar before the cloth arrives at the comb and
over the other bar after it has passed the comb, which thus hold up the cloth as
it is passing under and against the teeth of the comb.
The comb or its equivalent is or may be made of thin steel plate or other
suitable material with teeth and spaces of the desired width and it is screwed or
otherwise secured to a bar or shaft extending across the machine which bar or
shaft is in suitable bearings so that it can be oscillated by a handle projecting from
it and brought into a vertical position against a stop when acting on the cloth or
be turned away from and held in another position when it is not to act upon
the cloth.

page_text: The bearings in which the shaft or bar is placed to oscillate, on each side of the
machine are blocks arranged in guides (or in any other convenient manner) to
slide up and down vertically and these slide blocks are connected each with a
screw for raising and lowering the slide blocks so that the comb shaft or bar may
be adjusted and its comb may be made to act with greater or less pressure upon
the proofed and vulcanized face of the passing fabric before the farina or other
suitable powder is applied.
For producing wavy or zig-zag stripes the shaft or bar is arranged to slide or
move freely endways in its bearings in the direction of its length in any convenient
manner and it is moved to and fro as the cloth is passing and thus makes wavy
stripes.

The motion is imparted to the shaft or bar by an excentric, crank, or cam either
single or double acting, if produced by a single acting cam the reverse movement
is or may be imparted by a spring.
The excentric crank or cam receives motion by being geared with one of the
rollers over which the cloth passes and which cloth rotates the roller in passing.
The connection between the excentric or crank and the comb shaft or bar is or
may be through a collar loose on the end of the shaft or bar (but not at liberty to
move endways thereon) which will allow the shaft to be partly rotated while
receiving end motion, or in any other convenient manner. Or a cam is or may be
used giving motion in a line parallel with its axis of rotation, the path or face of
the cam acting directly upon a bowl on a stud in the end of the comb shaft or
bar-If the cam is single acting the bowl is kept against the cam by a spring.
When desired straight and wavy stripes are or may be produced at the same
time, by two combs one stationary for the straight stripes and the other moveable
as above described for the wavy stripes.
One comb in this case is arranged to operate before the other.
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
The production of ornamental effects upon india rubber waterproof fabrics
substantially as and in the manner bereinbefore described.
