Improvements in the Method of and Means for Repairing Inflatable
Articles Constructed of Indiarubber.
I, ROBERT DAWSON KAY of 41 Corporation Street Manchester in the County
of Lancaster, Indiarubber Manufacturer,; do hereby declare the nature of this
invention to be as follows:-
This invention relates to the method of and means for repairing inflatable
articles constructed of indiarubber, such as foot-balls, the air.tubes of pneumatic
tyres and the like.
}
According to this invention. I prepare discs or pieces of natural or unvulcanised
sheet indiarubber of a sufficient size to adequately cover any cuts or punctures
which it may be desired to repair. I also provide a supply of indiarubber
solution or cement and of cold vulcanising solution. In repairing the articles, J.
coat or smear the neighbourhood of the cut or puineture with the cement and wet
the cement with the vulcanising solution. Then the disc or piece of natural slicet
rubber is applied and this in turn is wetted with the cold vulcanising solution.
The procedure may however be varied in some cases by applying the cold.
vulcanising solution once only, before or after the application of the natural
rubber. In either case the result is that the patch and the cement are vulcanised
upon the article and being thus of precisely the same nature will have the same.
degree of extensibility and power of recovery after extension and become
homogeneous therewith.

Improvements in the Method of and Means for Repairing Inflatable
Articles Constructed of Indiarubber.
I, ROBERT DAWSON KAY of 41 Corporation Street, Manchester in the County
of Lancaster, Indiarubber Manufacturer, 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 relates to the method of and means for repairing inflatable
articles constructed of vulcanised indiarubber, such as foot-balls, the air tubes of
pneumatic tyres, and the like.
According to this invention I prepare discs or thin pieces of natural or unvul-
canised indiarubber, each of a size sufficient to adequately cover any cuts or
punctures which it may be desired to repair. I also provide a supply of india-
rubber solution or cement, and of cold vulcanising solution which may consist of
chloride of sulphur dissolved in such a solvent as bisulphide of carbon. The
rubber cement may be made up for use in small collapsible tubes, and the
vulcanising solution in a small bottle, and these may be arranged with a sufficient
Paine R37

pocket or in a tool bag or the like, for immediate use.
"
In repairing the articles, the neighbourhood of the cut or puncture having been
cleaned, is smeared with the rubber cement. Then, the cement may be wetted
with the vulcanising solution, and the natural rubber disc be instantly applied, after
which the vulcanising solution may be smeared over the patch and the surplus
rubber cement around it. The process may be modified in the following manner:-
The neighbourhood of the cut or puncture having been cleaned, and the rubber
cement having been applied as before, the disc of natural rubber is wetted on one
side with the cold vulcanising solution and is then immediately applied with its
wetted side to the rubber cement so as to cover the cut or puncture. Then, as
before, the patch and the surplus rubber cement are smeared with the vulcanising
solution which quickly dries. The final application of the vulcanising solution
may in either case be omitted, but it will then be desirable to smear the patch
with powdered French chalk or to cover it with a fabric or tissue, because of its
adhesiveness.
By this process and means the patch and the cement are vulcanised upon the
article, and being thus of precisely the same nature will have the same degree of
extensibility and power of recovery after extension and become homogeneous
therewith.
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 :-
1. The hereinbefore described method of repairing cuts and punctures in
inflatable vulcanised indiarubber articles, substantially as and by the means set
forth.
2. Means for repairing cuts and punctures in inflatable indiarubber articles,
and which consist of discs or thin pieces of natural rubber in combination with
rubber cement and cold vulcanising solution, employed substantially as hereinbefore
described.
