Improvements relating to Pneumatic Tyres and other Air-inflated
Articles.
I, RICHARD WAPSHARE, Major 3rd Lancers, Hyderabad Contingent, at present
of Narramore, Moreton Hampstead, Devonshire, do hereby declare the nature of
this invention to be as follows:-
The chief object of the present invention is to facilitate the repair of air-inflated
or pneumatic tyres, when they become punctured.
To this end, I fill, or partly fill, the air tube with a fibrous material, such as
cotton wool. This material, which does not add appreciably to the weight, is intro-
duced into the tube before the ends are joined up, preferably in the form of a rope
or sliver, with or without a light sheath of rubber to give it strength.
When the tube is punctured, it will only be necessary to inject a small quantity
of india rubber solution into the hole, and press the tube down on the rim. The
solution is caused by the cotton wool to spread out in the neighbourhood of the
puncture, and to form a film, which adheres firmly to the interior of the tube, and
effectually seals up the hole from the inside. The tyre thus repaired is ready for
immediate use.
The invention is applicable both to single tube tyres, and to tyres which consist
of an outer cover and an inner air tube.
In repairing the latter, it is by no means
necessary to remove the cover, for if the damaged place in the cover is found, the
point of the injector may be introduced through the same into the inner tube,
either through the puncture hole, or through another hole near, made by the
introduction of the injecting instrument. The solution injected will spread
sufficiently to seal the puncture and the hole made by the injector.
It will be observed that, according to this method of repairing, there is no patch-
ing or application of solution on the outside of the tube, so as to render it sticky,
and likely to adhere to the cover. Moreover, the repair can be effected without
removing the tyre from the wheel.
The same method is applicable for repairing punctured air-cushions, horse-
collars, mattresses, or similar air-inflated articles.

Articles.
I, RICHARD WAPSHARE, Major 3rd Lancers, Hyderabad Contingent, at present
of Narramore, Moreton Hampstead, Devonshire, 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:
The chief object of the present invention is to effect, in a more expeditious
manner than heretofore, the permanent repair of air-inflated or pneumatic tyres,
when they become punctured, but the invention also applies to the repair of other
air-inflated articles, should they, from any cause, be punctured.
According to my invention, as applied to pneumatic tyres, the air tube is filled,
or partly filled, with a loose fibrous or fluffy material, such as cotton wool. This
material, which does not add appreciably to the weight, is introduced into the tube
before the ends are joined up, preferably in the form of a rope or sliver.
When the tube is punctured, it will only be necessary to inject a small quantity
of india rubber solution into the hole, and press the damaged part of the tube
down upon the wool. The solution is caused, by the cotton wool, to spread out in
the neighbourhood of the puncture, and to form, with some of the wool, a matted
patch, which adheres firmly to the interior of the tube, and effectually seals up
the hole from the inside. The tyre thus repaired is ready, when re-inflated, for
immediate use.
The invention is applicable both to single-tube tyres, and to tyres which consist
of an outer cover and an inner air-tube. In repairing the latter, it is by no means
necessary to remove the cover, for, having found the damaged place in the cover,
the point of the injector may be introduced through the same into the inner tube.
The instrument may be passed into the inner tube, either through the puncture
hole, or through another hole in close proximity thereto, which may be made by
the introduction of the injecting instrument. The solution injected will spread
sufficiently to seal both the puncture and the hole made by the injector.
In the accompanying drawing I have shown my invention as applied to tyres
'for cycles which comprise an inner or air tube and an outside cover.
Fig. 1 is an outside view, partly in section.
Fig. 2 is a cross section, with the point of the solution-injector inserted, with
the view of repairing a puncture.
Fig. 3 is also a cross section of the tyre, at a later stage of the repairing
operation.
A is the cover and B the air tube. C is a rope or sliver of cotton wool or similar a
fibrous fluffy material introduced within the tube B. D is the wheel rim. E is
the nozzle of the solution injector seen in Fig. 2.
To repair a puncture, it is only necessary to insert the point of the injector E
at or near the hole, as shown at Fig. 2, and to inject a small quantity of rubber
solution or equivalent cement. The injector is then withdrawn, and the damaged 4
portion is pressed down upon the fibrous material within the tube (see Fig. 3), and
the hole becomes effectively sealed from the inside.
The apertures of the injecting nozzle are by preference at the side, but I make no
claim in connection with such construction.
It will be observed that, according to this method of repairing, there is no 4
patching or application of a solution on the outside of the tube, so as to render it
sticky, and likely to adhere to the cover. Moreover, as above stated, the repair can
be effected without removing the tyre from the wheel.

page_text: The repair of punctured air-cushions horse collars, mattresses, or similar air-
inflated articles, will be effected in the same manner.
It is obvious that cotton wool is not the only loose fluffy material which can be
used for repairing tyres according to my invention, but it is, for various reasons,
the material I prefer to employ.
I may add, however, that in the case of single tube tyres, which have to be
submitted to considerable heat after the fibrous material has been introduced, the
latter must be such as not to be destroyed by the heat employed. I may mention
asbestos fibre as a suitable fluffy material for use in this case.
It will be understood that the wool or other material used is not in any sense a
packing for giving mechanical support to the tyre, and rendering it rideable, in
case of puncture, but merely a means for scaling the puncture in conjunction with
the solution injected in the manner explained.
G
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
The herein before described method of repairing air-inflated articles, wherein pre-
viously inserted loose fibrous material is employed, some of which, when adhesive
solution is introduced at or near the puncture, forms with the solution a matted
patch, adhering to the interior of the air chamber, and serving to seal the hole and
repair the damaged part.
