Improvements in the Manufacture of Waterproof Fabrics and
Spreading Machines applicable for Coating or Proofing Rubber
Proofed Fabrics.
We, LOUIS FRANKENSTEIN, of Victoria Rubber Works, Newton Heath, Man-
chester, in the County of Lancaster, Manufacturer, and CIIARLES LYST, of Victoria
Rubber Works, Newton Heath aforesaid, Manager, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the waterproofing of fabrics by applying a coating
or covering of rubber to the cloth.
Hitherto in the coating of the cloth it has been customary to apply a number
of very thin layers of rubber to the cloth say about 6 more or less according
to the quality of the fabric to be produced. This process necessitates the pass-
ing of the fabric through the machine for every layer or coat applied and the
drying of the rubber after each coat.
We have found that by applying the desired amount of rubber proofing at
one operation and then compressing the rubber in a suitable manner after it
has been coated upon the cloth that satisfactory results are obtainable.
Our invention consists essentially in proofing the fabric by one or two opera-
tions compressing the rubber upon the fabric when spread by means of two three
or more spreading gauges and in spreading apparatus constructed with two or
more spreading knives arranged around a spreading cylinder.
In carrying out the invention we construct the spreading machine with a large
spreading roller with two three or more spreading gauges thereon. Or. two or
more spreading rollers may be employed their bearings either arranged in an
are or horizontal with a spreading gauge to each.
The cloth is preferably coated with a preliminary coating in the usual way of
suitable consistency to fill up the interstices but for fine or closely woven cloth
such preliminary coat may be dispensed with.
The first gauge under which the fabric passes is set furthest from the roller
and each in succession nearer to the roller than the preceding one.
The full weight of rubber is applied to the cloth at the first gauge and the
cloth passes under the next and following gauges which compress the rubber
which has been laid on removing any surplus rubber.
A calendar or two facing bowls are fitted at the end of the drying table to
finally compress and finish the proofing after the drying.

Proofed Fabrics.
We, LOUIS FRANKENSTEIN, of Victoria Rubber Works, Newton Heath, Man-
chester, in the County of Lancaster, Manufacturer, and CHARLES LYST, of Victoria
Works, Newton Heath aforesaid, Manager, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to the waterproofing of fabrics by a coating covering
or layer of rubber to the cloth.
Hitherto in the coating of the cloth it has been customary to apply to the
surface thereof successively a number of thin layers of rubber say about 6 or
more according to the quality of the fabric to be produced each of such layers
of the rubber coating being applied separately and then dried the fabric having.
to pass through the machine a corresponding number of times. Thus for 6 layers
of rubber the cloth has to pass through the machine and be dried 6 times and
consequently entailing a great deal of time and labour.
We have found that equally good and satisfactory results are obtainable and
a_great_deal_of_time-and-labour-saved-in-the-process-by-applying-the-full-quan-
tity of rubber or an excess quantity in the first instance (or at any stage say
after one two or more coats have first been applied) by a suitable gauge and
then compressing and removing excess rubber by a series of following gauges
each succeeding one placed nearer or closer to the fabric than the preceding one.
Our invention consists essentially in a process for applying the rubber coating
to the fabric in one (or two) operations in which the full or an excess quantity
is first applied and the rubber compressed and consolidated and the excess removed
by a number of successive gauges which gradually approach more nearly to the
fabric.
The invention will be fully described with reference to the accompanying
drawings in which is illustrated a machine designed for carrying out the inven-
tion.
Fig. 1, is a longitudinal section.
Fig. 2, side elevation of the spreading end of the machine.
Fig. 3, detached section of one of the spreading gauges.
Fig. 4, side elevation of the calendering end of the machine.
Fig. 5, plan of the spreading end of the machine partly in section.
Fig. 6, plan of the calendering end of the machine.
The spreading machine is constructed with a large spreading roller or cylinder a
around the periphery of which are placed two three or more spreading gauges
under which the fabric passes.
The spreading gauges are set in succession the first gauge under which the
fabric passes being set furthest from the roller or cylinder a and each gauge
in succession nearer thereto than the preceding one.
Behind the spreading cylinder a is placed the steam heated drying table c and
at the other end of the drying table a pair of calendering rollers d and a pair
of winding rollers e. Or two or more spreading rollers may be employed their
bearings either arranged in an arc or horizontal with one or more spreading
gauges to each.
In carrying out the process the cloth is first preferably coated in the usual
way with a preliminary coating of suitable consistency to fill up the interstices

page_text: or pores of the cloth but for fine or closely woven cloth such preliminary coat
may be dispensed with.
The cloth to be waterproofed is passed through the machine illustrated over
the cylinder a and under the successive gauges b. The full weight or an excess
of weight of rubber dough is applied to the cloth at the first gauge and as the
cloth passes forward the rubber is compressed at each succeeding gauge which
is set closer to the cylinder than the preceding one and any surplus rubber
removed.
This compressing of the rubber between a successive number of gauges and
then calendering or facing it gives a coating equal to that applied layer by layer
as the compression to which it is applied removes all porousness.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The process of waterproofing fabrics with rubber which consists in applying
the full weight or excess of rubber to the fabric and then compressing the same
and removing excess by a series of gauges substantially as described.
2. The process of waterproofing fabrics with rubber which consists in apply-
ing the full weight or excess of rubber to the fabric and then compressing the
same and removing excess by a series of gauges each successive gauge set closer
to the fabric and the cylinder than the preceding one substantially as described.
3. The process of waterproofing fabrics with rubber substantially as described
and shown.
4. A machine for coating or waterproofing fabrics with rubber having all
the parts constructed and arranged in combination substantially as described
and shown.
