PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Pneumatic and like Tyres.
I, PRESTON DAVIES, of Townmead Works, Wandsworth Bridge Road, Fulham,
in the County of Middlesex, Tyre Manufacturer, do hereby declare the nature of
this invention to be as follows:-
My present invention relates to the restraining or confining medium or jacket for
the inflatable tube of a tyre and has for its object the improved construction thereof
in such manner that while it is not liable to stretch in a direction diagonal to the
length of the completed article it is free to do so to a limited extent otherwise and
is provided with interstices to allow for displacement of the air contained within
the tube upon any extra pressure being put upon the tyre when in use.
The jacket is composed of yarns or threads laid together in one direction upon,
and secured to, a suitable foundation preferably of thin sheet rubber but according
to my invention certain of the yarns or threads are omitted leaving the said
foundation uncovered. The said yarns or threads run in a direction diagonal to the
length of the completed jacket. A strip of material so constructed and of a width
preferably about double that of the completed jacket is taken and folded
longitudinally. If the strip is folded with its rubber foundation inwards the two
adjacent surfaces may be solutioned or secured together; if folded in the reverse
way a sheet of rubber may be placed in the centre and solutioned or secured
between the surfaces of the yarn or thread.
It will be seen that, owing to the folding of the material as described, a lattice
will be formed in the jacket having unrestrained interstices.
If intended for the jacket of a wired-on tyre the strip constructed as above
described may be provided with the usual pockets at its edges; if for a solid-wall
tyre it may be formed into a tube after folding as herein described, or alternatively
two tubes may be formed of slightly differing diameters each with the yarns and
spaces running in one direction only and the one inserted into the other in such a
manner that the direction of the yarns or threads and spaces of one are opposite to
those of the other the two being solutioned to each other.
The material as herein described may be made with the yarns or threads and
spaces running parallel with the length of the material as manufactured and strips
of the material of the required width may afterwards be cut therefrom on the cross
or bias.
The yarns or threads employed may either during or after manufacture of the
material be waterproofed in any convenient way.

I, PRESTON DAVIES, of Spencer House, Southfields, in the County of Surrey,
late of Townmead Works, Wandsworth Bridge Road, Fulham, in the County of
Middlesex, Tyre 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 :-
My present invention relates to the restraining or confining medium, or jacket,
for the inflatable tube of a tyre and has for its object the improved construction
thereof in such manner that while it is not liable to stretch in a direction diagonal
to the length of the completed article it is free to do so to a limited extent other-
wise and is provided with interstices to allow for displacement of the air
contained within the tube upon any extra pressure being put upon the tyre when
in use.
The accompanying drawings illustrate my invention, Figure 1 showing a piece of
restraining or confining medium partly folded over or completed as shown at the
end C and partly open as shown at the end D. The threads or yarns are only
shown in part of the figure. Figure 2 is a section through the line A-B of
Figure 1, and Figure 3 is an exaggerated view in section of one of the
pockets.
The jacket is composed of yarns or threads E laid together in one direction upon, and
secured to, a suitable foundation F preferably of thin sheet rubber but according to
my invention certain of the yarns or threads as shown at G are omitted leaving the
said foundation uncovered. The said yarns or threads E run in a direction diagonal
to the length of the completed jacket and they may be either simply planted or
stuck upon the foundation F or they may be first formed into a fabric by the
addition of a few fine cross heads H. A strip of material so constructed and of a
width preferably about double that of the completed jacket is taken and folded
longitudinally. If the strip is folded with its rubber foundation F inwards the two
adjacent surfaces may be solutioned or secured together; if folded in the reverse
way a sheet of rubber may be placed in the centre and solutioned or secured between
the surfaces of the yarn or thread.
Or obviously the material as herein described might be made with the yarns or
threads E and spaces G running parallel with the length of the material as
manufactured and strips of the material of the required width afterward, cut
therefrom on the cro-s or bias.
The yarns or threads employed may either
during or after manufacture of the material be waterproofed in any convenient
way.
It will be seen that, owing to the folding of the material as described with the
spaces G running diagonally on each side, a lattice of unrestrained interstices of
rubber or its equivalent will be formed in the jacket.
If intended for the jacket of a wired-on tyre, the strip constructed as above
described may be provided with the usual stitchings forming pockets at its edges to
contain wines K and such pockets may be lined with rubber, waterproofed or plain
canvas, or other desired material L. If for a solid-wall tyre the jacket may be
formed into a tube after folding as herein described, or alternatively two tubes may
be formed of slightly differing diameters each with the main yarns E and spaces G
running in one diagonal or spiral direction only and the one tube inserted into
the other in such a manner that the direction of the yarns or threads and spaces
of the one are opposite to those of the other the two being solutioned to each
other.
If the yarns or threads E are all laid adjacent to one another, that is to say if
the spaces G are filled in with yarns E, provided the material is doubled or folded

page_text: over as described a very serviceable jacket or confining medium, unstretchable in a
direction diagonal to its length and therefore free from what is known as " side-roll,"
is produced.
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 :-
1. In the manufacture of the restraining or confining medium for the inflatable
tube of a tyre, yarns or threads such as E secured to a foundation, but with spaces
such as G between them, so folded or placed as to run diagonally to the length of
the completed jacket and to form a lattice of unrestrained interstices.
2. A restraining or confining medium for the inflatable tube of a tyle
constructed substantially as herein described.
