1, JAMES JOSEPH WARRY, of 42 Melton Road, Birkenhead, in the County of
Chester, Commission Agent, do hereby declare the nature of this invention to be as
tollows:-
This invention has reference to velocipede and other wheel tyres of the pneumatic
type, namely, tyres within which an under pressure is employed
According to this invention, the tyre consists of a band, which when in place,
takes the shape in cross section of an arch, or tube of any desired form, and has at
each side a tubular extension which fits within an inwardly tuned edge forming a
Channel provided at each edge of the run, and these tubular extensions com-
municate with the interior of the tyre, so that when the tyre is inflated, the air
passes into the said tubes and they expand outwards, and fill said channels' edges,
and so hold the tyre in the rim Ui, as a modification of this, the tubular edges
may not communicate with the main tyle, but may be supplied with air fiom
separate branches from the filling or charging valve or filting of the tyre, or in
any suitable way
l'his tyle, in one form, is made of a construction which renders it capable of
being opened readily, by having overlapping edges on the part of the tyre which
comes against the rim, which edges are cemented together in such a manner that
they can be readily drawn apart should access to the interior of the tyre be
necessary A suitable form of um for this tyre is one where the part running
between the inwardly turned or inwardly and overturned channel edges, is flat, or
comparatively Hat, the usual groove in the centie being provided for the
spokeheads or fastenings which will be filled up by any suitable material
In one form of tyre 'constructed as described, the tubular parts may be formed
by cementing onto the main part of the tyre a stup of rubber in tubular form,
and outside this there may be provided a strip of canvas or tape, as a protecting
or strengthening stup and the whole may be vulcanized together The tyre
generally would be lined with or have within it one or more layers or pieces of
canvas, or other strengthening material, in the usual or any known way
A tyre made as described, being an-tight in itself, is intended to be used without
the ordinary inne au tube, but, if desired, under certain conditions, an inner air
tube may be used as the inflating or inflateable part of the tyie, in which case
the tubular holding edges, may be also inflated through suitable charging valves
or devices.
It is to be stated that the invention, the nature of which is above described, is

COMPLETE SPECIFICATION (AMENDED)
Improvements in or connected with Pneumatic Tyres.
I, JAMES JOSEPH WARRY, of 12 Melton Road, Bnkenhead, in the County of
Chester, Commission Agent, 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 has reference to velocipede and other wheel tyres of the pneumatic
type, namely, tyres within which an under pressure is employed
According to this invention, the tyre consists of a band, which when in place,
takes the shape in cross section of an arch, on tube of any desned form, and has at
each side a tubular extension which fits within an inwardly turned edge forming a
channel provided at each edge of the rim, and these tubular extensions com-
municate with the interior of the tyre, so that when the tyre is inflated, the air
passes from the main tube into the said tubes and they expand outwards, and fill
Said channels edges, and so hold the tyre in the m Oi, as a modiheation of
this, the tubular edges may not communicate with the main tyre but may be
suplied with an from separate branches from the filling or charging valve or
fitting of the tyre, or in any suitable way
This tyre, in one form, is made of a construction which renders it capable of
being opened readily, by having overlapping edges on the part of the tyre which
comes against the im, which edges are cemented together in such a manner that
they can be readily drawn apart should access to the interior of the tyre be
necessary A suitable form of m for this tie is one where the part running
between the inwardly turned on inwardly and overturned channel edges, is flat, or
comparatively flat, the usual groove in the centic being provided for the
spokeheads or fastenings, which will be filled up by any suitabile material
In one form of tyre constructed as described, the tubular parts may be formed
by cementing onto the main part of the tyre a stup of rubber m tubular form,
and outside this there may be provided a strip of canvas or tape, as a protecting
o strengthening stup and the whole may be vulcanized together
The tyle
generally would be lined with or have within it one or more layers or pieces of
canvas, or other strengthening material, in the usual or any known way
A tyre made as described, being an-tight, in itself, is intended to be used without
the ordinary inner an tube, but, if desired, under certain conditions, an inner an
tube may be used as the inflating or inflatable part of the tyre, in which case
the tubular holding edges, may be also inflated through suitable charging valves
or devices
The invention will now be described with reference to the accompanying
diawings, in which
Figure 1 is a cross section of the tyre, and
Figure 2 is a cross section of a modified form of same
a is the main arched portion of the tyre, bare the side tubes by which the tyre
is held in the m e are the passages connecting the interion of the tubes with
the interior of the part a, and d d' are overlapping edges of the part a
The w
18 designated e and the side channels in which the tubes fit are marked f. To

page_text: give the part a the requisite strength, and to prevent it from expanding when
under pressure, it is provided with canvas limings a a, the lining being carried
on somewhat into the tubes b, namely to a distance just beyond and under the
edges of the channels f, but the tubes are without canvas, being simply of
ubber, and are therefore capable of being expanded when filled with an under
pressure, and contracting when the pressure is removed.
The overlapping edges ale cemented together by india-rubber solution or
like cement, and when so joined the tyre forms a complete and closed tube from
which no au can escape, but, it, at any time, it is desned to have access to the
interior of the tyre, 2e the part, then these two edges can be readily torn
away from one another by the hand as the cement on solution, although it will
make an air tight joint between these edges by reason of such edges not being
under stretch and resting on the bottom of the me and with the au pressuie
on the inside pressing them one onto the other, will easily give way when the
tie is deflated and the edges i d' drawn away from one another
In using the tyre, it is placed in the um e with the tubes in the channels f, and
then blown up or inflated as usual through a tube and valve of any suitable kind,
the effect being that as the an increases its pressure in the tyre, it flows into the
tubes & through the holes and inflates them so that they fill the channels
bear fly the mne suilaces thereof
and
are
In the modification in Figure 2, the neck on entrance to the channels
disposed substantially in the horizontal plane, while the entrance or neck to such
channels in the um shewn in Figure 1 is substantially in the vertical plane
By this construction provide in the first instance a cheap and simple tyie
consisting of a single tube (e without an inner tube) having side tubular
fastenings with the ms, filled from the interior of the tyre, and, u the second
place, a single tube tyre having overlapping edges at the bottom, by which, though
normally closed and sealed, access can readily be had to the interior of the tyre
by drawing them apart
In some cases in lieu of having two holding in tubes, I may employ a single
tube placed in a groove or channel in or near the centie of the im, while the
overlapping fastening edges lie in the m to one side thereof
Having now particularly descubed and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is
1
A pneumatic tyre consisting of a single main inflation tube and a fastening
tube or tubes thereon, fitting in a channel on channels in the rim and connected
with the interion of the main inflation tube and overlapping edges, substantially
as set forth, and as shown in the drawings
A pneumatic lyre consisting of a single mam inflation tube and a fastening
tube or tubes therean, fitting in a channel or channels in the m, and having
overlapping edges by which the said main tube is sealed, said edges being disposed
so as to lie on rest upon the um substantially as and for the purposes set forth
The pneumatic tyre consisting of the tubular inflated part a with textile
shengthening lamma, fastening tubes & communicating with the interior of the
tubular party,
a me with channels f in which the tubes ble, and the
overlapping edges dd, as set forth with reference to and shown in the drawings
