PROVISIONAL SPECIFICATION.
Improvements in Means for Protecting, Strengthening, and Stiffening
Rubber Tubing and Hose.
I FRANK REDDAWAY of the Firm of F. Reddaway & Co. Limited of
Cheltenham Street, Peadleton, in the County of Lancaster, Manufacturers of
Machine Belting, do hereby declare the nature of this invention to be as
follows:-
My said invention relates to improved means for protecting strengthening and
stiffening rubber tubing and hose. Such rubber tubing and hose has been made
with a covering of open net work, which however has proved of but little practical
value as a protecting and strengthening means. Rubber tubing has also been
covered with a coil of wire, but this is expensive and of considerable weight.
My present invention consists in completely enveloping the rubber tubing in a
closely woven coating or outer tube of woven hose, the said tubular envelope being
woven in position upon the rubber hose. The said outer coating may be composed
of any suitable textile fibre capable of being so woven on the rubber tubing, such
for example as cotton, hemp, flax, wool or other suitable vegetable or animal
fibre.
In order to weave this outer coating or envelope upon the rubber tubing, I employ
a circular loom which I at present make use of in my business to weave circular
fabrics and hose. I need not describe the mechanism of this circular loom as its
construction forms no part of my present application, and no essential modification
of its construction is required to carry my present invention into effect. The rubber
tubing is fed into the loom and forms a central core upon which I weave the
envelope. This outer envelope is woven tightly upon the tube so as to surround
and cling to it. The rubber tubing is thus protected from wear and is also
strengthened to resist internal pressure, and stiffened so as not to be liable to form
"kinks when handled in long lengths.'

COMPLETE SPECIFICATION.
Improvements in Means for Protecting, Strengthening, and Stiffening
Rubber Tubing and Hose.
I FRANK REDDAWAY of the Firm of Frank Reddaway & Co. Limited, of
Cheltenham Street, Pendleton, in the County of Lancaster, Manufacturer of
Machine Belting, 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 and accompanying drawings:-
My said invention relates to improved means for protecting strengthening and
stiffening rubber tubing and hose. Such rubber tubing and hose has been made
with a covering of open net work, which however has proved of but little practical
value as a protecting and strengthening means. Rubber tubing has also been
covered with a coil of wire, but this is expensive and of considerable weight.

page_text: My present invention consists in completely enveloping the rubber tubing in a
closely woven coating or outer tube of woven hose, the said tubular envelope being.
woven in position upon the rubber hose.
The said outer coating may be composed of any suitable textile fibre, capable of
being so woven on the rubber tubing, such for example as cotton, hemp, flax, wool
or other suitable vegetable or animal fibre.
The said outer coating or envelope of textile material is or may be woven upon
the rubber hose in any suitable manner, but in practice I use a circular loom made
in accordance with an invention for which Letters Patent were granted to
Albert De Laski No. 1874 of 1887 and of which my firm is now the registered
proprietors.
I need not describe the mechanism of this circular loom as its construction forms
no part of my present invention and its utilization for the purposes of my invention
entails no essential change or addition. All that is requisite is to feed the rubber
tubing through the centre of the loom, or allow it to be drawn through as the
coating proceeds. The textile covering is woven closely and tightly upon the tube
so as to surround and cling to it. The annexed illustration is meant to give an idea
of the appearance of a portion of rubber tubing coated in the manner described.
For example the rubber tube is marked A and the woven coating B. The-lines
marked care intended to represent the warps and the lines d the weft which is
woven circularly into the warps in the manner described in De Laski's Specification.
The rubber A constitutes a central core upon which the covering B is securely and
tightly woven, so as to cling to and practically become of a piece with the rubber
tubing.
It is evident that any other circular loom capable of working in the same manner
as the De Laski apparatus might be used in carrying my invention into effect. The
rubber tubing is thus protected from wear and is also strengthened to resist internal
pressure.
The coated tubing as a whole is much stiffer and is not so liable to form "kinks"
when handled in long lengths.
Having now particularly described and ascertained the nature of my said
.invention and in what manner the same is to be performed I declare that what
I claim is.
Coating rubber tubing and hose with a protecting and strengthening covering
of textile fibre closely woven in position upon the rubber tubing.
