Improvements relating to Inflating and Manufacturing Elastic Tyres
used on Cycles, Motor Cars, and for other Purposes.
IWALTER WILLIAM COLLEY of Sandon Villa Townley Road Dulwich London Paper
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The inflating part of the invention consists essentially in inflating tyres (manu-
factured of rubber, rubber cloth, canvas fibre leather or any suitable material)
with a composition made from glue, gelatine, syrup, glue and treacle, glycerine,
or the like. This composition when mixed and cooked (in a similar way to that
of preparing glue, viz. by boiling) resemble when allowed to set, pure india rubber
so far as being elastic and pliable.
To inflate a Tyre I pump this composition in a liquid state into it, so that when
the composition is cool or set the tyre is inflated with a solid mass of composition
that has the same advantages as if made from pure rubber at the same time
being far more elastic and pliable, with the advantages of a tyre inflated with
compressed air but without the disadvantages.
In making my composition I do not restrict myself to gelatine or glue mixed
with any other suitable material for the purpose of making a pliable composition,
the same results might be brought about by gum, size, or the like.
Another feature of this invention is as follows:-
In manufacturing a tyre I employ round the periphery of the wheel, a number
of cup shaped holes into which I let a number of round balls that have been
previously inflated with a composition as described above, these balls are made
much larger than the holes so that when the pressure takes place on the wheel
these balls are not submerged in the cup, these balls round the periphery of the
wheel are covered by a shield or covering that is fixed round the wheel and so
forms an outer tyre, I sometimes construct these balls round the wheel so as to
dispense with the outside covering or tyre but for wheels required to be used on
the highway I prefer the outside covering.
Another feature in this invention in manufacturing tyres, I cast the composition
in a mould so constructed to the shape of the wheel, I then cover this com-
position with an outside covering of rubber or rubber and material mixed and so
make the casting air tight by this said outer covering. This tyre is then placed
on the wheel and is made to act the same as an inflated tyre and it has all the
advantages of one.

I WALTER WILLIAM COLLEY, of Sandon Villa Townley Road, Dulwich, London,
Paper 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 inflating tubular tyres manufactured of suitable flexible
material, such as india rubber, with a composition in a liquid state, which when
set and cool, is elastic and pliable like pure india rubber.
A suitable composition according to this invention is prepared from a mixture
of gelatine and sugar, preferably glucose, as follows: Animal gelatine is first
soaked in cold water in the usual way for melting, that is, until it becomes soft,
and is then removed from the water and melted by heat. Glucose is boiled until
it becomes of the constituency of boiled sugar when the melted gelatine is stirred
into it, and the mass allowed to cool and set; afterwards it is again melted to
allow the air stirred in at the beginning to pass off; then the mass in its hot and
lion state is pumped into the tubular part of a tyre, the inlet closed and the
composition allowed to cool and set when the tyre is ready for use. Another plan
is to cast the composition in a suitable shape to be covered by the outer tyre, in
this way the inner tube would not be required.
The proportions of the ingredients for the composition employed, may be varied,
but I have found the following to give goods results: To every pound weight of dry
gelatine, add quarter of a pound of glucose. The same composition as is now used
for printers rollers may be used for the purpose of this invention, or a mixture of
glue and treaclé, or glue treacle and glycerine, or other known compositions, other
than india rubber or preparations of rubber, which become liquid by heat and
firm but elastic when cool.
Having now particularly described and ascertained the nature of this Inven-
tion, and in what manner the same is to be performed; I declare that what 1
claim is:-
1. The production of an elastic tyres for wheels, consisting in inflating a tube
or tubes such as is used with or for pneumatic tyres of wheels, with a composition
in a liquid state which when set is soft and pliable.
2. The production of an elastic tyre for wheels, consisting in casting from the
composition described a suitable ring to encircle the periphery of wheel and to be
secured to same by being enclosed by a casing such as is used to protect or form
the air tube of pneumatic tyres.
