PROVISIONAL SPECIFICATION.
Improvements in or relating to Pneumatio Tyres.
We, JOHN DRING and ERNEST HENRY JONES, both of 136 Great Saffron
Hill, in the County of Middlesex, Tyre Manufacturers, do hereby declare the
nature of our invention to be as follows:-
This invention relates to the canvas or similar covering usually employed as the
interior of the cover of a pneumatic tyre.
In carrying out this invention we make the canvas or similar lining of the tyre
cover capable of offering more resistance at the tread portion of the tyre to
puncture, than is usually the case, by thickening it up for a sufficient distance at
that portion. This is accomplished not by solutioning other thicknesses of canvas
upon a foundation, but by actually weaving the canvas thicker at those portions
than elsewhere. This may be accomplished by introducing extra threads,
particularly warp threads, in the process of the weaving, and thus making the
"solid".
material thicker at the required part technically described as having a
centre or portion.
In order to obtain distinctive effects in these tyres and that they may be readily
identified as of particular manufacture, we introduce various coloured threads or
dye certain portions. A convenient way of introducing this feature is to have the
warp threads of certain parts of the fabric of different colours, so that longitudinal
bands of the special colours will extend throughout the fabric.

Improvements in or relating to Pneumatio Tyres.
We, JOHN DRING and ERNEST HENRY JONES, both of 136 Great Saffron
Hill, in the County of Middlesex, Tyre Manufacturers, 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 the canvas or similar covering usually employed as the

In carrying out this invention we make the canvas or similar lining of the tyre
cover capable of offering more resistance at the tread portion of the tyre to
puncture, than is usually the case, by thickening it up for a sufficient distance at
that portion. This-is accomplished not by solutioning other thicknesses of canvas
upon a foundation, but by actually weaving the canvas thicker at those portions
than elsewhere, by introducing extra threads or thicker threads or both, extra and
thicker, particularly warp threads, in the process of the weaving, and thus making
the material thicker at the required part, technically described as having a "solid
centre or portion.

page_text: In order to obtain distinctive effects in these tyres and that they may be readily
identified as of particular manufacture, we introduce various coloured threads or
dye certain portions. A convenient way of introducing this feature is to have the
warp threads of certain parts of the fabric of different colours so that longitudinal
bands of the special colours will extend throughout the fabric.
In the accompanying drawings Fig. 1 shows in perspective a short length of
canvas lining made according to this invention. Figure 2 is a transverse section
of the same.
In the drawing A is the thickened tread portion A 1 being some of the extra
warp threads by which in this instance the thickening is produced; these threads
lie lengthwise in the fabric, that is to say, circumferentially therein when the
fabric is in place upon the wheel and are at the upper and lower surfaces or sides
thereof. B are marginal portions of the fabric, shown darker in the.drawing to
indicate longitudinal bands of special colour such as are hereinbefore referred to.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a pneumatic tyre a canvas or similar fabric having a
tread.
66 solid" thickened
2. In a canvas or fabric for pneumatic tyres thickening the tread portions by
weaving in the extra or thicker threads or both extra and thicker threads.
3. In a pneumatic tyre a canvas or similar fabric having distinguishing colours.
4. The combination in a canvas or fabric for pneumatic tyres of a thickened
tread and distinguishing colours.
