PROVISIONAL SPECIFICATION.
Improvements in and connected with Indiarubber Tyres.
We, JOSEPH MOSELEY, Indiarubber Manufacturer, and BENJAMIN BLUND-
STONE, Manager, both of the Chapelfield Works, Ardwick, Manchester, in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:
--
This invention relates to indiarubber tyres and it has for its object to increase
the strength and durability of such tyres.
A tyre constructed according to these improvements consists of a central india-
rubber core or tube, a surrounding of yarn or wire braided thereon, and an outer
tube or covering of indiarubber. This constitutes the simplest form of the tyre,
which may
in some cases consist of alternate layers or surroundings of yarn or wire
and of indiarubber upon a central indiarubber tube or core.
The yarn or wire is laid upon the core, tube, or layer, by means of a braiding or
similar machine, so that the yarn or wire forms a complete and seamless fabric round
the core and within the substance of the tyre.
In carrying out our invention, we prefer to make in the first place, a length
of braided or similarly protected core or tube; this is then cut into lengths as
may be determined by the circumference of the wheels with which the tyres may
be used. Each length is then surrounded with a layer of indiarubber, and if
desired, by one or more layers of fabric and indiarubber, but the outer layer or the
outer layers as may be preferred in each case, do not extend to the end of the
braided or protected core or inner tube, but stop short some inches from each end
according to the length and diameter of the tyre. The two ends of the braided or
protected core or inner tube are then brought together to form a butt joint and
are served with a surrounding of fabric to connect the ends and strengthen the
joint. Upon this surrounding there is laid one or more layers of indiarubber or of
indiarubber and fabric to bring the part over the joint to the same or to a similar
character and dimensions as the rest of the tyre which is then placed in a mould
and vulcanised in the usual manner.
These improvements are particularly applicable to cushioned and pneumatic tyres,
in which cases the central part of the tyre consists of a tube or of the cushioning
material.
It will be understood that we do not limit ourselves to the hereinbefore indicated
method of manufacture, as this may be carried out in many different methods.

COMPLETE SPECIFICATION.
Improvements in and connected with Indiarubber Tyres.
We, JOSEPH MOSELEY, Indiarubber Manufacturer, and BENJAMIN BLUND-
STONE, Manager, both of the Chapelfield Works Ardwick Manchester in the
County of Lancaster, 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 relates to indiarubber tyres and its object is to increase their
strength and durability.
A tyre constructed according to these improvements consists, in its most
elementary form, of a central indiarubber core or tube, a surrounding of yarn or
Price Ad

page_text: of fine wire braided or similarly intersected thereon, and an outer tube or covering
of indiarubber. This form may be modified as to the order and number of the
successive layers upon the central indiarubber tube or core, to a very great extent,
the essential condition being one or more layers of braided or similarly intersected
yarn or fine wire in or around the tyre.
The yarn or fine wire may most conveniently be laid upon the core, tube, or
layer, by means of a braiding or similar machine, but it will be obvious that the
surrounding or layer of braided or intersected yarn or fine wire may be inde-
pendently formed into a seamless tube and be drawn upon the indiarubber core or
tube or be used as the basis of the indiarubber tube or tyre, but in all cases so that
the yarn or wire forms a complete and seamless fabric around the core or centre
within the substance of the tyre.
In carrying out our invention, we prefer, in the first place, to make a length of
indiarubber core or tube braided or similarly protected with the intersected yarn or
fine wire; this long protected core or tube is then cut into shorter lengths the linear
dimensions of which are determined by the circumferences of the wheels upon
which the tyres are ultimately to be used. Each of these shorter lengths may
then be surrounded with a layer of indiarubber and if desired, with one or more
layers either of fabric or of indiarubber or of both fabric and indiarubber but the
outer layer or the outer layers as may be preferred in each case, do not extend to
the end of the braided or protected core or inner tube, but stop short some three or
four inches (more or less according to the dimensions of the tyre) from each end of
the tyre. The two ends of the braided or protected core or inner tube are then
brought together so as to form a butt joint and in this position they are served with
a surrounding of fabric such for example as a strip or strips of canvas, to connect
the ends and strengthen the joint. Upon this surrounding of fabric over the joint
there is laid one or more layers of indiarubber or of indiarubber and of fabric,
sufficient to bring the part over the joint to the same or to a similar character and
dimensions as the rest of the tyre, which is then placed in a mould and vulcanised
in the usual manner.
Although we prefer to make the joint as hereinbefore described before vulcanisa-
tion, this is not absolutely necessary, for the length of tyre may be vulcanised before
the joint is made.
We have described the best method of manufacture at present known to us,
but it will be obvious that this method may be varied in many ways; we desire
therefore that it should be understood that we do not limit ourselves to the precise
method set forth.
These improvements are particularly applicable to air inflated or pneumatic tyres
and to cushioned tyres, in which cases the central parts of the tyres consist respec-
tively of an indiarubber tube or of the cushioning material.
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,―
1. An indiarubber tyre having therein or thereon one or more seamless layers of
intersected yarn or fine wire, constructed substantially as herein before described.
2. The hereinbefore described method of joining an indiarubber tyre which con-
sists in stripping or stopping the outer layers a short distance from each end, in
bringing the ends together to form a butt joint, and in surrounding the joint with
servings of fabric and rubber to correspond with the remainder of the tyre,
substantially as set forth.
3. An indiarubber tyre, constructed and arranged substantially as and for the
purpose hereinbefore described.
