PROVISIONAL SPECIFICATION.
An Improved Method of and Means for Rendering Pneumatic Tyres
Unpuncturable.
OLIVER FRANCIS PICKERING, 16, Park Crescent, Monkgate, York, Gun
Finisher, do hereby declare the nature of this invention to be as follows:-
A series of discs or plates of metal or other suitable material, fastened on to a
band, these plates or discs to overlap each other as shewn on Fig. 1, and continued
in a like manner for the circumference of the tyres which will form a complete
armour, proof against punctures.
These plates or dises may be fastened by means of teeth, legs, rivets or cement
on to the said band, which may be of silk rubber, linen, or other suitable material,
or they may be made to form part of the outer cover of any existing type of tyre
now in use, or be worked in, or on to a hose pipe tyre to render the same puncture
proof.
I reserve the right to make the aforementioned plates either round, square, oval,
oblong, or angular, and to be fastened on to a band, or to each other in the form of
a chain.
Fig. 2 shows a leg stamped out of the middle of disc.
Fig. 3 shows leg bent down ready for fastening on to a band.
Figs. 4 and 5 are modifications, with legs at edges instead of the middle.

An Improved Method of and Means for Rendering Pneumatic Tyres
Unpuncturable.
I, OLIVER FRANCIS PICKERING, 16, Park Crescent, Monkgate, York, Gun
Maker, 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:-
-
A series of discs or plates of metal or other suitable material fastened on to a
band, these plates or discs to overlap each other, and continued in a like manner
for the circumference of the tyres which will form a complete armour, proof against
punctures.
These plates or discs may be fastened by means of teeth, legs, rivets or cement
on to the said band, which may be of silk, rubber, linen, or other suitable material,

page_text: or they may be made to form part of the outer cover of any existing type of tyre
now in use, or be worked in or on to a hose pipe tyre to render the same puncture
proof.
I reserve the right to make the afore-mentioned plates either round, square, oval,
oblong or angular, and to be fastened on to a band or to each other in the form
of a chain.
In order that my invention may be fully understood, I will now refer to the
annexed drawings, in which:-
Figure 1, plan view shewing the plates or discs in position.
Figure 2, view of plate or disc having the fastening pieces stamped out of the
middle of same.
Figure 3, side elevation of same.
Figure 4, side elevation of modified form of disc or plate.
Figure 5, plan view of same.
Figure 6, elevation of further modification.
Figure 7, cross section through the tyre shewing my invention in position.
The discs or plates a are provided with the pieces or legs which may be stamped
or pressed out of the discs as shewn in Figures 2, 3, 4, 5, and 6, and one or more
legs or stamped out pieces may be employed. These legs or pieces are for the
purpose of securing the plates or discs to a band which encircles the tyre, being
passed through said band and bent over so as to maintain the discs or plates in
position, and which are so arranged as to overlap one another, thus forming a
flexible protecting covering. I sometimes find it convenient to dispense with the
projection or legs and secure the discs or plates in position by means of cement,
or 1 may rivet the discs or plates upon the band or tyre.
Although I have shewn for purposes of illustration the discs secured to the band,
they may be fixed to the outer cover of the tyre, or other suitable parts for the
purpose of protecting the tyre from puncture. The essential feature of my inven-
tion consists in the overlapping discs or plates for the purpose of preventing
puncture and at the same time giving flexibility.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is: :-
1. In means for preventing the puncture of tyres: the employment of discs
having pieces, legs, or projections formed upon same for the purpose of attaching
the discs in position; said discs being arranged so as to overlap one another.
2. A disc or plate having one or more legs or pieces formed upon same, said legs
or pieces enabling the disc to be secured in the required position upon a tyre for
the purpose of preventing puncture.
