Complete Specification Left. 8th Feb., 1900-Accepted, 17th Mar.,
1900
We, WALTER SWAIN and LEONARD HARTLEY SWAIN, both of 177, Belmont Road,
Sharples, Bolton, in the County of Lancaster, Land Agents, do hereby declare
the nature of this invention to be as follows, that is to say:-
In our Specification No. 12230 of 1898 we have described a pneumatic tyre or
cover consisting of a band made by uniting to a central width of braided or equiva-
lent fabric side widths or borders attached while they are under tension, so that
when this composite band is bent in to the circular form which it would have in
surrounding the rim of a wheel, it tends to take the form of a tube. Our present
invention relates to a treatnient of such a composite band which ensures that it
takes and maintains, the form of a tube which, being placed on the rim of a wheel
and inflated or having a tube within it inflated, is held firmly on the rim with-
out other means of fixing.
For this purpose we provide as a former or mould, a ring, which may be of
wood, having a circular section so that it has the size and shape of the intended
pneumatic tyre. On this ring we fix the composite band of braided or equivalent
fabric stitching it or otherwise temporarily securing its edges together along the
inner side of the ring. We then fix over the whole surface of the band by caout-
chouc or other elastic cement, threads laid longitudinally along it, the effect of
this being that when the band is removed from the former, it retains the tubular
form imparted to it, so that it can easily be applied to the rim of a wheel and
caused to grip it as before mentioned.
We prefer to make the borders of the band a little wider than is required for
the tube, so that after the longitudinal threads are laid on, the borders can be
turned over and cemented for the purpose of strengthening the edges.
The band formed as above described is completed by an external coating of any
known kind to form the tread of the tyre; and, when the band is to be used by
itself without an internal pneumatic tube, it has to be rendered impermeable to
air by internally coating or lining it with caoutchouc or equivalent material.

An Improvement in Pneumatic Tyres
We, WALTER SWAIN and LEONARD HARTLEY SWats, both of 177, Belmont Road,
Sharples, Bolton, in the County of Lancaster, Land Agents, do hereby declare
the nature of this invention and in what manner the same is to be performed, to

page_text: be particularly described and ascertained in and by the following statement, that
is to say
Iu our Specification No. 12230 of 1898 we have described a pneu-
matic tyre or cover consisting of a band made by uniting to a central width
of braided or equivalent fabric side widths or borders attached while they are
under tension, so that when this composite band is bent into the circular form
which it would have in surrounding the rim of a wheel, it tends to take the form
of a tube. Our present invention relates to a treatment of such a composite band
which ensures that it takes and maintains the form of a tube which, being placed
on the rim of a wheel and inflated or having a tube within it inflated, is held
firmly on the rim without other means of fixing.
In the accompanying sheet. of drawings, which are illustrative of our said in-
vention:
-
Fig. 1 is a perspective view of a portion of a fabric part or cover for a pneumatic
tyre illustrating one method of construction in accordance with our said invention.
Fig. 2 is a sectional view of the former or mould used in the manufacture of
our improved pneumatic tyre cover.
Similar figures and letters of reference indicate similar parts throughout the
several views.
In carrying our invention into effect we provide as a former or mould a ring a,
see Fig. 2, which may be of wood, or other suitable material, being of a suitable
shape in cross section, so that it has the size and formation of the intended
pneumatic tyre. On this ring a we fix the composite band of braided or equivalent
fabric b, stitching it or otherwise temporarily securing its edges 1, 2, together
along the inner side a¹ of the ring a. We then fix over the whole surface of the
band by caoutchouc or other elastic cement, threads laid longitudinally along
it, these threads e being either cut to the required lengths and their ends folded
or wrapped over each other, or a thread or threads may be coiled or wound con-
tinuously around the mandrel, thus forming an endless fabric, the effect of this
being that when the band 6. is removed from the former a it retains the tubular
form imparted to it, so that it can easily be applied to the rim of a wheel and
caused to grip as before mentioned.
.
We prefer to make the borders d, of the band a little wider than is required
for the tube, so that after the longitudinal threads are laid on, the edges p
of the borders d d¹ can be turned over and cemented for the purpose of strengthen-
ing the edges.
The band formed as above described, is completed by an external coating of
any known kind to form the tread of the tyre, and when the band is to be used
by itself without an internal pneumatic tube, it has to be rendered impermeable
to air by internally coating or lining it with caoutchouc or equivalent material,
and by laying its inner edges one over the other.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim.is:-
A pneumatic tyre or cover for the tube of such a tyre, consisting of a composite
band as of braided or equivalent fabric, over which is or are laid and cemented
In the manner set forth a longitudinal thread or threads, as c substantially as
and for the purpose herein specified.
Dated this 7th day of February 1900.
