PROVISIONAL SPECIFICATION.
A New or Improved Means for Protecting Pneumatic Tyres from
Puncture.
I, JAMES PATRICK O'NEILL, of Monasterevan, in the County of Kildare, Ireland,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention is intended for use in connection with pneumatic tyres and it has
for its object the making of such tyres puncture proof while at the same time not
destroying their elasticity.
In carrying my invention into effect I take quill or horn which I extend into
thin flat plates or strips by any convenient means such for example as heating
and pressing
I then take these plates or strips of quill or horn and inbed them or otherwise
work them into the substance of the tread of the tyre itself during its manufacture.
This may be done while the tyre is being moulded and is in a soft condition or
during any stage of the manufacture of the tyre that is found convenient.
Or as an alternative, the tyre may be made of two parts, an outer part and an
inner part and the strips or plates of quill or horn may be placed between these
two parts. After the strips or plates have been laid in the desired position say on
the inner part of the tyre the outer part can be closed over it and fixed to it in
any convenient manner. The two parts of the tyre can for example be cemented
or solutioned so as to join them together without destroying their form.
The strips or plates may be made in any convenient form such as triangular,
square or polygonal or indeed of any, shape which when the plates are together
enables them to cover a surface without having unnecessary interstitial spaces.
The said strips or plates may be arranged side by side or they may overlap one
another or the edges may dovetail or serrate into one another: and they are made
sufficiently thin to bend or give in the desired direction. They may be laid in
the tyre in position parallel or approximately parallel to the tread.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My invention is intended for use in connection with pneumatic tyres and it has
for its object the making of such tyres puncture proof while at the same time not
destroying their elasticity.
In carrying my invention into effect I take quill or horn which I extend into
thin flat plates or strips by any convenient means such for example as heating
and pressing.
I then take these plates or strips of quill or horn and inbed them or otherwise
work them into the substance of the tread of the tyre itself during its manufacture.
This may be done while the tyre is being moulded and is in a soft condition or
during any stage of the manufacture of the tyre that is found convenient.
Or, as an alternative, the tyre may be made of two parts, an outer part and an
inner part and the strips or plates of quill or horn may be placed between these
two parts. After the strips or plates have been laid in the desired position say on
the inner part of the tyre the outer part can be closed over it and fixed to it im
any convenient manner. The two parts of the tyre can for example be cemented
or solutioned so as to join them together without destroying their form.
The strips or plates may be made in any convenient form such as triangular;
square or polygonal or indeed of any shape which when the plates are together
enables them to cover a surface without having unnecessary interstitial spaces.
The said strips or plates may be arranged side by side or they may overlap one
another or the edges may dovetail or serrate into one another; and they are made
sufficiently thin to bend or give in the desired directions. They may be laid in
the tyre in position parallel or approximately parallel to the tread.
Having now described the nature of my invention in general terms I shall
proceed to show how it is to be or may be carried into effect and for that purpose
I shall refer to the accompanying drawings which illustrate forms typical of
my invention.
Figure I is a plan of one form of my invention in which strips of horn are
employed as a protecting device and in this figure it is assumed that the outer
rubber portion or tread has been removed. In the said figure, 1 is the tyre, the
rubber portion extending between the edges 2 and 3. 4 is a canvas insertion
extending between the edges 5 and 6. 7 and 8 are strips of horn overlapping at
the part 9, the whole being covered by the soft rubber tread.
The relative positions of these parts are diagrammatically represented in
Figure II in which 10 is the soft rubber tread. The strips may be either apart
from the insertion as in the figure or they may lie on the insertion as in
Figure I.
Figure III illustrates a form which differs from that shown in Figures I and II
in that instead of employing strips of horn strips or plates of quill 11 are employed,
the said strips or plates overlapping at the parts 12.
Figure IV illustrates a form which differs from that shown in Figure III in that
the strips or plates of quill instead of lying longitudinally lie transversely.
Figure Villustrates a case in which the quill strips or plates are arranged in
two rows instead of in a single row as in the previous cases.
In the said figures similar numerals of reference indicate similar parts.
I sometimes find it convenient to use two layers of canvas insertion, one under
the strips or plates and the other over the same.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is;
1. In a pneumatic tyre the employment of plates or strips of quill or horn
substantially as and for the purpose set forth.
2. In a pneumatic tyre the combination of strips or plates of quill or horn with

forth.
3. In a pneumatic tyre the arrangement and combination of parts substantially
as and for the purpose set forth.
