S.W. Lady JOHN PERCY ARUNDEL BOWLEY Percy Villa Tooting S. W. Engineer
do hereby declare the nature of this invention to be as follows:-
Our invention has for its object the repairing of the pneumatic or air tyres now
commonly in use on velocipedes or other vehicles also hose, pipes, or water or other
vessels as in title above.
To carry out this our invention in the one form we use preferably round rubber
rod or other springy or elastic material to form a plug or stopper which we extend
or compress and bind over with a thread or wire or other suitable material or
covering in such a manner as to make it become of very much smaller diameter or
thickness. In this state the plug or stopper is inserted or forced into the puncture
or prepared hole in the tyre hose, pipes, water or other vessels to be repaired. We
then release the rubber plug or stopper by pulling or untying any suitable slip
knot or fastening by any suitable means, after which the whole of the thread
covering or envelope may be easily unwound or taken off and the plug allowed to
expand or return to its original form or size so far as the hole or puncture will
allow.
Or the thread covering or envelope of the rubber or other plug may be secured
by a gum or some suitable matter or compound which when soaked or saturated
with water, spirit or other liquid will dissolve and release the thread covering
or envelope which may be then unwound or taken off and so allow the said plug
to contract and expand whilst in the puncture or prepared hole..
In another form the rubber or other elastic or springy material is hollow and of
suitable bore and length, of which we may tie or stop up the one end. We then
proceed to push a rod down the hollow of the said plug, and stretch the said plug
or rubber over it until the diameter or thickness of the said plug or stopper is so
reduced as to allow it to be inserted or pushed into the puncture or prepared hole
in the tyre hose, pipes, or water or other vessels to be repaired. This being done
the rubber may be relaxed and the rod taken out therefrom. The said plug
expands and springing back into its normal size or form tightens in the hole or
puncture.

Improvements in the Repair of Pneumatic Tyres, Hose, Pipes,
or Water or other Vessels.
We MARGARET ELIZABETH TARVER of The Glen Glen Eldon Road Streatham
Gentlewoman and JOHN PERCY ARUNDEL BOWLEY of Percy Villa Longley
Road Tooting both in the County of Surrey Engineer 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:-
In pneumatic tyres hose pipes or water or other vessels of all descriptions that
contain or exclude or wherethrough passes air or water or other fluid or liquid a
great evil is experienced in that the material or materials of which such articles or
LD O27

page_text: appliances or apparatus are made is or are so liable to have holes or cracks or
punctures created or produced whereby and wherethrough the fluid or liquid will
escape or enter and this is especially the case when such articles or appliances or
apparatus are made of india rubber canvas or other flexible material as also to some
extent when the same are made of metal plates or other rigid material and still
more especially when the fluid or liquid is under pressure. Furthermore this evil
is all the more experienced when as is particularly the case with pneumatic tyres
the articles or appliances or apparatus that contain the fluid or liquid are placed or
taken or moved over rough ground or other surface or stones or other roughnesses
excrescences or projections which can so easily crack or puncture the same. At
the present time too it is a comparatively long and expensive operation to repair
these tyres hose pipes or water or other vessels when so holed or cracked or
punctured even if it can be done at all.
Now the object of this our invention is to provide means whereby pueumatic
tyres and more especially single tube pneumatic tyres hose pipes or water or other
vessels can when necessary be very rapidly easily and cheaply repaired with
extremely great efficiency.
To carry out this object we take a piece of india rubber or other suitable
expansible material of any convenient size length and diameter and preferably it
may be of a circular shape in cross section or thereabouts and this piece is
preferably stretched longitudinally it may be to its extreme capability whereby
obviously its diameter will be greatly reduced or in any other convenient manner
by pressure or otherwise this diameter is greatly reduced and round this piece so
treated is tightly wound fine string or thread or cord or wire or other similar and
suitable appliance or appliances by which it is maintained in such condition with a
greatly reduced diameter throughout its whole length.
If the whole or crack or puncture that is to be repaired be not round or nearly so
it is most convenient to make the same round or as nearly so as may be desired by
burning or cutting or melting or otherwise.
Then in cases where it is desired or required to retain or contain the fluid or
liquid as for example in pneumatic tyres hoses pipes and such vessels as cans
kettles and the like this piece of india rubber or other material so-treated as afore-
said and made into a plug being properly proportioned to the hole or crack or
puncture also so treated as aforesaid is passed therethrough from the outside and
is held therein to fill the same when the string or other appliance the end
whereof is duly presented therefor on the outside is unwound off such plug com-
mencing from and at the inner end of the same which inner end therefore
expands filling tightly such hole or crack or puncture and creating by its inherent.
expansibility and consequent expansion an enlarged head on the plug on the inner
surface of the tyre or hose or pipe or vessel and afterwards when the string or
other appliance has been entirely and completely unwound off such plug another
like head is similarly created on the plug on the outer surface of the tyre or hose
or pipe or vessel and thus and in this manner the required repair is properly
effected and completed as desired.
On the other hand in cases where it is desired or required to exclude the fluid
or liquid as for example in such vessels as ships and boats cans kettles and the
like that are or may be immersed or partly immersed in the fluid or liquid this
piece of india rubber or other material so treated as aforesaid and made into a
plug being properly proportioned to the hole or crack or puncture also so treated
as aforesaid may preferably be passed therethrough from the inside and be held
therein to fill the same when the string or other appliance the end whereof is
duly presented therefor on the inside is unwound off such plug commencing from
and at the outer end of the same similarly filling tightly the hole or crack or
puncture and creating the enlarged head on the plug on the outer surface of
the vessel as also afterwards on the inner surface thereof in manner as herein-
before described to properly effect and complete the required repair as is desired.
A very convenient method of creating these plugs consists in taking a long strip

page_text: of the india rubber or other material of the desired diameter and duly stretching
the same as is herein before described and then winding the string or other
appliance round the same in certain short lengths each length being so pro-
portioned and arranged as to provide for and constitute one plug and when all
these lengths have been so wound cutting or dividing this long strip into the
arranged for and desired number of plugs ready for use.
A suitable method of winding the string or other appliance round the plug
consists in commencing in the usual manner so to wind the same at one end of the
plug and at the other end thereof forming in and by the string or other appliance
a slip knot or other similar and customary or other device that can be released or
done away with without actual and immediate contact or that is to say from the
other end of the plug and then the free end of the string or other appliance is laid-
along the length of the plug to this other the commencing end thereof.
A number of bands of some flat and preferably narrow and it may be textile or
other material may also be used to surround and bind the plug instead of the
string or other appliance which would similarly be passed therearound and secured
in position in any convenient and usual or other manner it may be by a solution of
india rubber or other adhesive material and these bands either immediately before
or after the plug is or has been passed through the hole or crack or puncture could
or would be moistened or otherwise treated as may in each case be appropriate to
release the bands or the ends of the same and thus allow the creation of the
required two heads on the plug in manner as herein before described when these
bands have loosened themselves or have been loosened and it may be have been
removed.
It may also frequently be desirable to treat the plug itself as also sometimes the
string or other binding appliance or appliances with a solution of india rubber or
other adhesive material which will tend in the first place to keep the string or
other binding appliance or appliances in its or their proper place or places on the
plug ready for use and then in the second place when the same is or are unwound
or removed will cause the body and it may be the heads also of the plug to adhere
to the walls of and the surfaces near the hole or crack or puncture.
It may also be desirable and more especially in and with pneumatic tyres hoses
and other articles or appliances or apparatus that are made of india rubber or other
expansible material to surround and bind the central part of each plug with and by
a ring or short sleeve of metal or other rigid or non-expansible material or it may
be a separate short length of string or other appliance or a separate short band
which will not be loosened or removed when the plug has been placed in position
in the hole or crack or puncture by which arrangement and method of procedure
there will be no danger that the body of the plug will by its expansion injure or
put out of shape the tyre or hose or other article or appliance or apparatus with
which this plug is used and by the walls of which the same is surrounded while at
the same time the required repair is properly effected and completed by the
two heads on the two ends of the plug created in manner as hereinbefore
described.
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
The plug for the repair of pneumatic tyres hose pipes or water or other vessels
made and litted and treated and used substantially as and for the purposes herein-
before described and declared.
