PROVISIONAL SPECIFICATION.
Improved Means of Repairing Pneumatic Tyres.
I, HENRY CHARLES BEARD, of 3, Laurel Terrace, High Road, Cricklewood,
London, N.W., Manufacturer of Cycles, do hereby declare the nature of this inven-
tion to be as follows:-
A ready means of repairing the outer cover of a pneumatic tyre when cut or
damaged, equally applicable to the repair of a tear or puncture in an inner tube.
When a tyre is badly damaged considerable time is lost by having to stitch, or
in some way join the parts together to resist the strain of the compressed air,
otherwise the cut would open and the inner-tube be forced through and burst.
To prevent this I provide patches of a prepared canvas, or other suitable material
made to the required widths and lengths to suit the tyre in use having at the two
edges a piping or enlarged edging. The patch will be made of sufficient width
that when fitted to the inside of the cover, the edges may fold over the wired edges
of the cover, and the piping or enlarged edging will be retained or held above the
wires of the tyre cover, and between the inside sides of the rim, the patches will
thus securely resist the strain at the point where the tyre is damaged and prevent
the pressure of the air forcing the inner tube through.
By a like means repairs may be made to an inner tube, when otherwise a much
longer time would be required by having to wait for the solution to set before
proceeding.
The prepared patches should not be made of equal widths throughout but
rather wider at the ends, to cause a greater strain in the centre part than at the
ends.

Improved Means of Repairing Pneumatic Tyres.
HENRY CHARLES BEARD, of 3, Laurel Terrace, High Road, Cricklewood,
London, N.W., Manufacturer of Cycles, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-

damaged, equally applicable to the repair of a tear or puncture in an inner tube.

otherwise the cut would open and the inner-tube be forced through and burst.
To prevent this I provide patches of a prepared canvas or other suitable material
made to the required widths and lengths to suit the tyre in use having at the
edges a piping or enlarged edging. The patch will be made of sufficient width
that when itted to the inside of the cover the edges may fold over the wired edges
of the tyre-cover C shown in Fig. 1. The piping or enlarged edging B Fig. 1 & 2
will be retained or held above and between the wires of the tyre-cover and the rim.
The patches will thus securely resist the strain at the point where the tyre is
damaged and prevent the pressure of the air forcing the inner-tube through
By a ke means repairs may be made to an inner-tube by the prepared patch being
placed over and surrounding the part damaged after a quick repair has been made
thereby protecting and bearing the strain at the damaged part of the inner-tube
even while the outer cover may be almost past repair, otherwise a much longer
time would be required by having to wait for the solution to properly set before
proceeding to infate. The prepared patches should not be made of equal width
throughout but rather wider at the ends to cause a greater strain in the centre
part than at the ends shown in Fig. 2 D. Referring to drawerings Fig. 1 repre-
sents the repairing patch in position. Fig. 2 the repairing patch laid flat. Fig. 3
section of repairing patch showing the piping or enlarged edging B.
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:
Prepared patches formed of canvas or other suitable material having piping
or enlarged edging substantially and for purpose herein described and illustrated
in Figs. 1, 2, & 3 of the accompanying drawings.
