PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic and similar Tyres.
We, JOHN DAVENPORT SIDDELEY of 35 Acomb Street Manchester in the
County of Lancaster, Shirt Cutter, and JOHN LINDLEY CARR, JAMES CARR, and
WILLIAM SMITH CARR of the firm of James Carr & Sons, Clarence Mills, Chester
Road, Manchester in the County of Lancaster, Manufacturers, do hereby declare
the nature of this invention to be as follows:-
These improvements relate to pneumatic and similar tyres and their objects are
to simplify the construction of such tyres, to render them more durable by
minimising the risk of bursting, and to facilitate their attachment to the rims of
velocipede and other wheels.
In carrying out our invention, the air-containing inner rubber tube is enclosed
within a woven tube or hose. This tube or hose has woven with it or otherwise
secured to it two flaps which extend around the rim and may be cemented thereto
and to each other in the usual manner. These flaps may be joined to the woven
tube at opposite ends of a diameter, or at any intermediate positions between the
edges of the rims and the tread of the tyre. It is preferred that the flaps are
continued the whole length of the tyre, but they may, if desired, be broken away
at intervals.

COMPLETE SPECIFICATION.
Improvements in and relating to Pneumatic and similar Tyres.
We, JOHN DAVENPORT SIDDELEY of 35 Acomb Street Manchester in the
County of Lancaster, Shirt Cutter, and JOHN LINDLEY CARR, JAMES CARR and
WILLIAM SMITH CARR, of the firm of James Carr & Sons, Clarence Mills,
Chester Road Manchester in the County of Lancaster, Manufacturers, 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 :-
These improvements relate to pneumatic and similar tyres, and their objects are
to simplify the construction of such tyres, to render them more durable by
minimising the risk of bursting, and to facilitate their attachment to the rims of
velocipede and other wheels.
In carrying out our invention, we arrange the air-containing tube of the tyre
within a woven tube or hose which forms the essential feature of our invention, and
which has woven with it or securely attached to it, two wings or flaps. The tube
and the wings are formed of a textile material, such as linen, and the wings join
the tube along longitudinal lines corresponding with the edges of the rim of the
wheel. Thus, if the rim extends half way around the tyre, the wings will be joined
to opposite diameters of the tube. Generally, however, the rims of the wheels do
not extend to one half of the diameter of the tyre, and the wings therefore, are
joined to the tube at something less than 180 degrees apart, as will be determined
in each case by the width of the rim.
It is preferred that each of the wings should be continuous, but they may if
desired, be absent at intervals along the length of the tube.

page_text: When the tyre is arranged upon the rim of the wheel, the wings are cemented or
otherwise secured over the inner part of the rim, and it is preferred that the wings
shall be of such a width that each one will cover nearly the whole width of the
back of the rim, so that the first wing is cemented upon the rim, and the second
upon the first. The flaps are slit where it is required that they shall pass the
spokes.
We will more particularly describe in what manner we carry our invention into
practice with reference to the accompanying drawings, in which:
Figure 1 represents a cross section of the tube and wings, and of the air con-
taining tube therein; and,
Figure 2 illustrates the method of weaving the wings with the tube.
In each of the figures, where the parts are represented, W indicates the wings,
T the woven tube, P the air containing tube, and U the indiarubber tread commonly
employed outside the air containing tube.
In weaving the flaps with the tube, we prefer to divide the circumference of the
tube and the wings into five parts and to employ a separate warp and two separate
shafts for each part. There are thus ten shafts and five warps. This division into
five parts is indicated by Figure 2 where the several divisions or parts are
numbered 1, 2, 3, 4, and 5, respectively.
The order in which the successive shoots of weft are taken, may be as follows.
First shoot, through parts 1, and 2. Second shoot, through parts 3, and 4. Third
shoot, through part 2. Fourth shoot, through parts 3, and 5, part 5 being one of
the wings. Fifth shoot, through parts 5, and 3. Sixth shoot, through part 2.
Seventh shoot, through parts 4, and 3. Eighth shoot, through parts 2, and 1. The
eighth shoot completes the round.
It will be obvious that other divisions of the tube and wings may be taken, and
that the shoots of weft may be taken in other orders than those hereinbefore given,
but we have so far found that the described method of weaving produces the best
result. It will also be obvious that instead of weaving the wings together with the
tube, they may be sewn or cemented thereon; but the results thus obtained are
inferior to those obtained by wearing, and they are generally more costly.
The method of application of the tube and wings to the rim of the wheel is
illustrated by Figure 3, in which R is the rim of the wheel and S is one of the
spokes. Only one section of the rim is shewn and part of the spoke, this being
sufficient for the purpose. As represented by the figure, the tyre has been applied
to the wheel, and one of the wings W has been cemented upon the inner part or
back of the rim. The other wing will be cemented upon the first.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is―
In a pneumatic or similar tyre, a woven tube having two wings or flaps woven or
secured thereon, substantially as and for the purpose hereinbefore described and as
illustrated by the accompanying drawings.
