PROVISIONAL SPECIFICATION:
Improvements in Means employed for Repairing Pneumatic Tyres.
I, JOHN LEWIS WILES, of 30 Barden Road, Tonbridge, in the County of Kent,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The object of my present invention is to provide a simple means for repairing a
puncture in a pneumatic tyre without using rubber solution.
In carrying my invention into effect. I form two plates of metal or other suitable
material. These plates are preferably of circular form; one of said plates is
perforated with a countersunk hole and has a rounded outer surface; the other
plate has a perforation or hole which is screw threaded to receive a screw passed
through the countersunk hole in the other plate, and in some cases the screw
threaded plate may have a projection at the back to enable a longer screw to
be used and to enable it to be handled more easily. Any other method of drawing
the two plates and holding them together may be employed.
The method of repairing a punctured tyre with the apparatus hereinbefore
described is as follows.
The screw-threaded plate is passed through the hole in the rubber tube, which
will stretch sufficiently for this purpose. It is then held by means of the projection,
the outer plate is placed in position, and the two plates are drawn together by means
of the screw, thereby holding the rubber tube firmly between them..

Improvements in Means employed for Repairing Pneumatic Tyres.
I, JOHN LEWIS WILES, of 30 Barden Road, Tonbridge, in the County of Kent,
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 :-
The object of my present invention is to provide a simple means for repairing a
puncture in a pneumatic tyre without using rubber solution.
In carrying my invention into effect I form two plates of metal or other suitable
material. These plates are preferably of circular form; oue of said plates is
perforated with a countersunk hole and has a rounded outer surface; the other
plate has a perforation or hole which is screw threaded to receive a screw passed
through the countersunk hole in the first plate, and in some cases the screw
threaded plate may have a projection at the back to enable a longer screw to be used
and to enable it to be handled more easily. Any other method of drawing the two
plates and holding them together may be employed.

page_text: My invention is represented in the accompanying drawings, in which :-
Fig. 1 is an exterior view, Fig. 2 is a plan and Fig. 3 is a vertical section,
of a puncture stopper constructed according to my invention, and Fig. 4 is a plan of
the lower part of the same.
Fig. 5 is a section and Fig. 6 is an underside view of a similar stopper of smaller
dimensions, and Fig. 7 is a cross section of part of a pneumatic tyre showing the
smaller puncture stopper in use.
a b are two plates of metal or other suitable material, which preferably are of
circular form. The plate a is perforated with a countersunk hole a¹ and has
rounded outer surface; the plate b has a screw threaded perforation or hole b¹,
which receives a screw passed through the countersunk hole a¹ in the plate a; the
plate has preferably a projection at the back to enable a longer screw to be used
and to enable it to be handled more easily; if desired the plate b may be used
without such projection 62, but this form is not so easy to handle as that shown in
the drawings.
The method of repairing a punctured tyre with the apparatus hereinbefore
described is as follows:-
The screw threaded plate 6 is passed through the hole in the rubber tube d, which
latter will stretch sufficiently for this purpose. It is then held by means of the
projection 6, the outer plate a is placed in position, and the two plates are drawn
together by means of the screw c, thereby holding the rubber tube d around the
puncture firmly between them. e is the outer cover of the tyre. The invention is
however applicable for repairing single tube pneumatic tyres.
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 :-.
CLAIMS.
1. In means employed in repairing pneumatic tyres, the combination of countersunk
perforated outer plate, under plate having a screw threaded hole or perforation, and
a screw passing freely through the hole in the outer plate and screwing into the
screw threaded hole or perforation of the under plate, substantially as herein shown
and described.
2. The combination with the parts forming the subject of the first claim, of
