I, WILLIAM HOCKADAY, Sales Agent, of Delabole, Cornwall, do hereby declare
the nature of this invention to be as follows:-
This invention relates to pneumatic tyres for the wheels of velocipedes and
vehicles.
The object of the invention is to provide a ready means of repairing the tyre in
case of puncture, or to otherwise strengthen or repair the tyre.
The invention consists of providing an extra half tube to the inside of the inner
tube of the tyre or to the inside of the tyre cover.
The two edges of the half tube are preferably attached one on each side of and at
about the middle of the inner tube or at the same position in the tyre cover. The
half tube can be laid against either the upper or lower side of the inner tube or
tyre.

1, WILLIAM HOCKADAY, Sales Agent, of Delabole, Cornwall, 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 pneumatic tyres for the wheels of velocipedes and
vehicles.
The object of the invention is to provide a ready means of repairing the tyre in
case of puncture, or to otherwise strengthen or repair the tyre.
The invention consists of providing an extra half tube of india-rubber or other
flexible material to the inside of the inner tube of the tyre, or to the inside of the
tyre cover, or to the inside of a single tube" tyre.
The two edges of the half tube, which I will call the reserve strip, are preferably
attached one on each side of, and at about the middle of, the inner tube or at the
same position in the tyre cover, and single tube tyre. The reserve strip can be
laid against either the upper or lower outer surface of the inner tube of the tyre, or
against either the upper or lower inner surface of a single tube tyre.
I will now describe the invention with reference to the accompanying drawings
in whichi:-

Fig. 1 shows a cross section of a single tube" pneumatic tyre in its normal
condition when unpunctured.
Fig. 2 shows a similar tyre after having been punctured and repaired with the
reserve strip c.
Fig. 3 shows a cross section of a pneumatic tyre with the reserve strip applied
between the outer cover and the inner air tube. The reserve strip is shown in its
secondary position viz. as sealing a puncture. The dotted lines indicating the
first position before puncture.
a is the tyre, attached in any preferred manner to rim b, c is the reserve or repair-
ing strip attached by its two edges to the inside of the tyre a. As will be
understood when the tyre is unpunctured the reserve strip c is placed as shown in
Fig. 1. When a puncture has taken place the strip c is placed in the position
shown in Fig. 2, thus preventing leakage of air from the tyre.
Referring to Fig. 3. The reserve strip c is shown as applied to a pneumatic
tyre, consisting of an outer cover and inner or air tube.
For convenient handling the reserve strip is attached by one of its edges only,
to the inside surface of the outer cover. Assuming the strip to be in its first
position as shown by the dotted line, when the tyre is punctured, both the outer
cover and the air tube are removed and the reserve strip reversed, the air tube
and outer cover are then replaced and the air tube again inflated. The reserve
strip in its altered position covers the puncture in the air tube and the outer cover
and thus seals it
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
claim is:
-
1. In a pneumatic tyre, the repairing strip c attached by its two edges to the
inside surface of the air tube of said pneumatic tyre as herein described and set
forth.
2. In a pneumatic tyre the repairing strip c attached by one of its edges to the
inside surface of the outer cover of said pneumatic tyre as herein described and set
forth.
3. The improved tyre consisting of a pneumatic tube with inner reserve strip,
for the wheels of velocipedes and other vehicles, as herein described and set forth.
Dated this 22nd day of March 1898.
