Improvements in the Manufacture of India-rubber Tubing and other
India-rubber Articles.
I, JOHN PHILLIPS JONES, trading as THE RELIANCE RUBBER AND HARD WOOD
COMPANY, of 216, Upper Thames Street, in the City of London, and 4, Elder Street,
in the City of Edinburgh, do hereby declare the nature of this invention to be
as follows:
The object of the present invention is to provide india-rubber tubing and other
articles which, while retaining more or less their resilient or elastic quality, shall be
wholly impermeable to air or gas, or less permeable than india-rubber articles such as
are at present commonly employed, for example, tubing for connecting gas-stoves
and other gas-fittings.
In applying my invention to the manufacture of india-rubber tubing for example,
I form the inner and outer portions thereof of india-rubber in the usual manner, but
between the two I insert in the course of manufacture a layer of thin india-rubber
tissue, which, being much less permeable than the indiarubber comprising the inner
and outer portions of the tube, will render the whole practically impermeable, and at
the same time will not destroy the resilient or elastic property of the tube, so that it
may be stretched over the nozzle and other similar portions of the fittings with great
ease.
In some cases, instead of india-rubber tissue, I may employ other similar and
suitable materials, such, for example, as gutta-percha, or cat-gut, which may be
preferably employed in the form of a tape wound helically round the outer surface
of the inner portion of the tube, or balata, or a suitable composition of glutinous.
impermeable material may be applied in a more or less liquid or plastic form.
It is obvious that my invention is equally applicable to the manufacture of india-
rubber goods generally where impermeability of the material is a desideratum.

what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of the present invention is to provide india-rubber tubing and other
articles, which, while retaining more or less their resilient or elastic quality, shall
be wholly impermeable to air or gas, or less permeable than india-rubber articles
much as are at present commonly employed, for example, tubing for connecting gas-
stoves and other gas fittings.
In order that my invention may be clearly understood, I will proceed to describe
its application to the manufacture of india-rubber tubing, for example, Figure 1 of
the accompanying drawings illustrates a short length of tube with parts removed
as hereinafter described. Figure 2 is a transverse section of such tube. I form the
inner portion a and the outer portion b of india-rubber in the usual manner, but
between the two portions a and b, I insert in the course of manufacture a layer
of thin tissue c, which, being much less permeable than the india-rubber comprising
the inner and outer portions a and b will render the whole of the tube practically
impermeable, and at the same time the resilient or elastic property of the tube
will be preserved, so that it may be stretched over the nozzle and other similar
portions of the fittings with great ease.
The tissue c is shewn in Figure 1 wound helically round the tube, but I do
not confine myself to this mode of applying the tissue, as it may be varied
according to circumstances.
I prefer to employ gutta-percha tissue, but in some cases I may employ other
similar and suitable materials, such, for example, as thin india-rubber tissue or catgut
which may be preferably employed in the forin of a tape wound helically round the
outer surface of the inner portion of the tube, or balata, or a suitable composition
of glutinous impermeable material may be employed in a more or less plastic
form.

It is obvious that my invention is equally applicable to the manufacture of
india-rubber goods generally where impermeability of the material
desideratum.
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:
First. In the manufacture of india-rubber tubing and other india-rubber articles,
the employment of a layer of gutta percha tissue in the thickness of the material
forming the said tubing or other article, substantially as herein before described, and
for the purpose specified.
Second. In the manufacture of india-rubber tubing and other india-rubber articles,
increasing the impermeability thereof by the introduction of a layer of gutta-percha
or india-rubber tissue, catgut, balata, or other suitable glutinous impermeable material
substantially as herein before described.
Third. India-rubber tubing and other india-rubber articles having a layer of
impermeable material in the thickness thereof, substantially as hereinbefore
described.
