PROVISIONAL SPECIFICATION..
Improvements; in and in connection with Pneumatic Tyres.
I, THOMAS RICHARD PINER, 10 Tyndall Road, Leyton, Essex Secretary, do
bereby declare the nature of this invention to be as follows:-
וווי
My, invention relates to improvements in the air or gas bags of pneumatic tyres
generally and has particular reference to the invention for which Letters Patent
have already been granted to me No. 11378 A.D. 1893. In that invention I
described my method of constructing the air or gas-bag of a pneumatic tyre in cross
sectional divisions or spaces by placing & fixing therein by solution or otherwise a
like number of partitions of the same material as the gas bag or any other
preferably flexible substance suitable for the purpose. I also fully explained my
method of attaching the outer cover or wearing surface to the rim of the wheel to
which my invention was applied this method of fastening the cover had of
necessity to be performed on the outer side of the rim in consequence of inability
to remove the outer cover or wearing surface of the tyre from the rim for repairs
if fastened in any other manner, the gas bag being so constructed that when
inflated there were no means for deflating it, & consequently the pressure upon the
cover was such that as described above it had of necessity to be fastened to the
outer side of the rim in order to facilitate its casy removal when necessary...
By my present invention I provide a method of easy deflation of the gas or,
air
bag thus overcoming the necessity for the use of any attachment of the cover on
the outer edge of the wheel rim, and by the arrangement 'I describe hereafter it
will be readily understood that my invention may be used in combination with any
of the outer covers at present in use irrespective of the method by which they are
attached to the rim of the wheel.

'
I carry my invention into effect by constructing a gas or air bag substantially
as described in the Letters Patent No. 11378 A.D. 1893 before referred to, and
near to, and running in the same direction as the inflating tube or air conduit I
make an annular space or groove in which I place small air valves opening into this
annular space or groove, one to each sectional division, these small air valves
throughout the annular groove being all in communication with one master valve
by means of the annular groove, which acts as an air conduit, and tlie master valve
on being opened allows the air in the sectional' divisions of the gas bag to pass
through the small valves, & thence by way of the annular space or groove
through the master valve into the atmosphere. During inflation the master valve
is kept closed and the force pump used for inflating the gas-bag is attached to
a small metallic nozzle which need not of necessity be a valve. The metallic
nozzle and the master valve are placed in position in respect to each other as may
be most convenient.

I, THOMAS RICHARD PINER of 65 (late 10) Tyndall Road, Leyton Essex,.
Secretary 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:-
My invention relates to improvements in the air or gas bags of pneumatic tyres
generally and has particular reference to the invention for which, Letters Patent
No. 11378 A.D. 1893 have already been granted to me.
In that invention I described my method of constructing the air or gas bag.of a
pneumatic. tyre in cross sectional divisions or spaces by placing and fixing therein
by solution or otherwise, a like-number of partitions of the same material as the air
or gas bag or of any otlier substance suitable for the purpose.
"
By my present invention I provide a means of easy deflation of the gas or air
bag, thus, overcoming the necessity for the use of any attachment of the cover on
the outer edge of the wheel rim, and by the arrangement illustrated by the
accompanying drawings it will be readily understood that my invention may be
used in combination with any of the outer covers at present in use irrespective of
the method by which they are attached to the rim of the wheel,
In the accompanying drawings the invention is fully described and similar letters
of reference refer to analagous or similar parts.
.lii.
Eig, 1 is a longitudinal section of part of an air or gas bag illustrating my
improved method of deflation.
th.
Fig. 2 is a plan view of the same arrangement, and
Fig. 3, is a cross section thereof.

or gas
The sectional divisions. A are made of indiarublier or any other suitable flexible
substance. Bis the inflating tube or air conduit and is made in the form of an
annular space or groove to which are attached within the sectional divisions the
valves,Cone to each sectional division, and these valves C are all in communication
through the annular space with the master valve F. The simultaneous inflation of
the sectional divisions is carried out by attaching an ordinary, air pump to the
master valve F and by pumping air or gas into the annular space B, the air
thus pumped being distributed among the several seotional divisions through the
valves C. These valves C being made of indiurubber close automatically and are
kopt closed by the air pressure in the sectional divisions A of the air or gas bag.
Having described by the above references in what manner the bug is inflated
I now proceed to describe in what manner the air or gas bag is deflated. Gis an
annular space, or groove, running in the same direction as the annular space or
groove B and is similar to it in construction. Within this annular space or groove
or air conduit GI place a number of valves H one to each sectional division all of
them being in communication through the annular space G with the master
deflating valve J; & each opening outwards from the sectional divisions A into the
annular groove G. The two annular grooves or air conduità B & G are placed a
short distance apart and are sealed by a strip of any suitable ihflexible material
being placed over them & fixed by solution or otherwise.
1
To deflate the sectional divisions A the master' deflating valve Jis opened and
the pressuro from witliin the sectional divisions A opens valves H and the air or
gas passes from these sectional divisions A through the valves H and by means of
the annular groove G through the master deflating valve J into the atmosphere.
In the process of iuflation the master deflating valve J is kept closed.
The object of my invention is to localise any damage that may happen to the air
or gas bag of a pneumatic tyre by puncture or otherwise, to the extent of the
sectional division damaged thus preventing the total collapse of the tyre.

page_text: The outer cover K may be attached to the wheel rim M by any of the approved
methods at present in use or by the insertion of canvas may be made part & parcel
of the air or gas bag the tyre being thus made complete as a single tube tyre.
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 [
claim is :-
In a sectional pneumatic tyre the method of simultaneously deflating the air
from the sectional divisions of the air or gas bag by means of the valve arrange
ment described in combination with an annular groove or air conduit substantially
as set forth.
