PROVISIONAL SPECIFICATION.
Improvements in Steam Vulcanising Woollen Waterproof Fabrics
for Garments.
SAMUEL WIENER, New Bridge Street Rubber Works Greengate Salford
Manchester, Lancs. Waterproof Garment Manufacturer do hereby declare the
nature of this invention to be as follows:-
The vulcanisation of rubber proofed woollen fabrics in steam cylinders at high
temperatures, thereby preventing the hardening of the cloth in cold atmospheres.
The principle of the invention is that previousely woollen goods could not be
vulcanized by steaming on account of the cloth fading when exposed to the action
of the steam and my improvement consists in the invention of an additional cylinder
or drum (furnished with an air valve from the main cylinder) to contain the cloth
wrapped upon a smaller drum thereby protecting the cloth from the action of the
steam & prevention of discolouration & disfigurement of the cloth.

COMPLETE SPECIFICATION.
Improvements in Steam Vulcanising Woollen Waterproof Fabrics
for Garments.
1, SAMUEL WIENER, of New Bridge Street Rubber Works, Greengate,
Salford, in the County of Lancaster, Waterproof Garment Manufacturer, 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:-
This invention is designed to provide an appliance wherein rubber proofed
woollen fabrics can be vulcanised by means of steam at a high temperature.
Hitherto it has not been practicable in the vulcanising of woollen fabrics to
treat them with steam as cotton goods are treated on account of the cloth fading
when exposed to the direct action of steam and other processes which have been
adopted bave left the cloth so that it would harden or become stiff in cold
atmospheres.
This invention consists essentially in the combination with a steam chamber of
an additional cylinder a drum provided with an air valve in which the cloth is
placed and a roller on which the cloth is wound whereby the cloth is protected
from the direct action of the steam whilst heated to the required temperature and
in the process of thus treating or vulcanising the fabric.
It will be fully described with reference to the accompanying drawings.

Fig. 2. Transverse sectional elevation.

Fig. 4. End elevation of same.
Fig. 5. Perspective view of the roller upon which the cloth is wound.
The steam chamber or cylinder A is constructed in the usual way to resist a
considerable amount of internal pressure being fitted with a tight fitting cover at
one end and a door B at the other.
An additional cylinder C of less dimensions is provided to fit inside the
chamber A. This cylinder is mounted upon a carriage D with wheels or runners d
so that it can be easily moved into or withdrawn from the chamber A.

It is

with a pipe E communicating with the atmosphere through which the vapours
rising from the rubber as it is heated can escape. The woollen fabric after it is
proofed is wound upon the roller F and placed inside the additional cylinder C the
ends of which are then tightly closed.
The rails G upon which the runners of the carriage D travel are secured
inside the chamber A by angle irons or other suitable means and similar rails are
continued outside the chamber for the carriage to run on to, a loose or removable
section of rail being placed near the front of the chamber to allow the door to open.
His the steam inlet pipe, I the exhaust and blow off pipe and J a pocket
provided in the door to receive a thermometer.
In operation the woollen fabric is wound upon the hollow roller F and placed
inside the additional cylinder C the ends of which are then closed. The cylinder C
is then pushed forward into the chamber A. and the two parts of the pipe E
connected together by union e to provide communication between the cylinder C
and the atmosphere to allow any vapour or gas arising from the fabric or rubber
When the door of the chamber A. is closed steam is admitted through
the pipe H until the desired pressure and temperature is obtained. The woollen
fabric being inside the closed additional cylinder C the steam has no direct action
upon it, and as a result gain all the advantages arising from vulcanising by steam
without damage to the fabric.
to escape.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the vulcanising of proofed woollen fabrics the process which consists in
subjecting the material to a high temperature produced by steam under pressure
whilst enclosed in a cylinder into which the steam does not enter so that the steam
has no direct action on the fabric substantially as described.
2. The apparatus for vulcanising proofed woollen fabrics by steam at high
temperatures consisting of a steam chamber A in combination with an additional
closed inner cylinder provided with an air valve or opening to the atmosphere into
which the fabric is placed and by which it is protected from the direct action
of the steam whilst being heated to the required temperature substantially as
described.
