PROVISIONAL SPECIFICATION.
Improvements in Woven Fabrios used for the Covers of Pneumatic
Tyres and other Articles having Curvilinear Surfaces.
I CHARLES HENRY GUEST of 45 Tower Road Birmingham Engineer do hereby
declare the nature of this invention to be as follows:-
My invention relates to woven fabrics more especially used to line, cover or
strengthen articles whose formation will not readily admit of flat fabrics being
used as for instance the lining of the covers of pneumatic tyres for wheels for
which purpose ordinary woven fabrics have hitherto been used and to better
enable the fabric to conform to the circumference of the tyre without unduly
stretching one part of the fabric or creasing the other part.
In carrying out my invention I prefer to weave my fabric in strips of a
suitable width in such strips I may weave the edges in the usual manner but in the
centre, preferably for about one third of the width of the strip I omit the threads
or strands which usually run lengthways of the strip thus allowing the central
portion of the strip to lengthen without lengthening the edges and so to conform
to the shape of the article to be covered, lined or strengthened, or instead of
weaving the edges in the usual manner I may weave loops in the said edges or I
may instead of weaving in strips weave in wide widths omitting the threads or
strands which run lengthways of the piece and commonly called the warp at
suitable distances so that the piece may be cut up into suitable strips each strip
having part of the warp omitted the object may also be attained by omitting the
shuttle or weft threads for a suitable distance and cutting the strips crossways of
the piece.

Improvements in Woven Fabrics used for the Covers of Pneumatic
Tyres and other Articles having Curvilinear Surfaces.
1, CHARLES HENRY GUEST, of 45, Tower Road, Birmingham, in the County
of Warwick, 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 invention relates to jackets or covers for pneumatic tyres horse-collars,
rollers for skates and other articles having curvilinear surfaces and usually coated
with india rubber lined with or having inserted therein a woven fabric.
Hitherto in manufacturing such articles a lining of ordinary woven fabric has
been employed, which, when the jacket or cover is bent to the required form or
curvature, causes the creasing of the edges of the cover or the undue stretching
of the central portions thereof.
Now the object of my invention is to obviate this objection and thereby better
enable the jacket or cover to conform to the required curvature without unduly
stretching one part, or creasing the other part, and to this end I line or cover the
india rubber with or insert therein a fabric having the edge portions woven in the usual
but without threads in one direction in the other or central portion thereof,
manner,

page_text: thereby leaving the threads in the other direction at the central portion of the
backing free to separate or move together to any required extent when the jacket
or cover is being shaped to the required curvature.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a view of a piece of backing suitable for application to a pneumatic
tyre jacket or cover, or a horse-collar, ball or the like:
Figure 2 is a view of a piece of fabric from which such strips of backing are
advantageously cut.
The strip of fabric shewn in Figure 1 has the warp threads only at the edges so
that the portions of the weft threads between the warps are free, when the backing
is applied to the jacket or covering, to open or separate to any desired extent to
enable the fabric to readily conform to the curvature of the tyre or other article.
This strip of fabric is advantageously cut from a piece of material woven as shewn
in Figure 2, that is to say, having, alternately, spaces between the sets of warp
threads, the said piece of fabric being subsequently divided at the lines a-a in
order to produce the strips as shewn in Figure 1.
Instead of omitting the warp threads as herein before described the weft threads
may be omitted in which case the fabric is divided transversely instead of
longitudinally, the width of the fabric being sufficient to enable strips of the
desired length to be obtained. I may in some cases if desired leave some of the
warp threads in the space between the woven edges.
The edges of the fabric may be made tubular when intended for pneumatic tyre
jackets or covers, to receive the wires for holding the tyre on the rin, such tubular
edges being made during the weaving of the strips, or formed by cutting from a
piece of fabric of the kind shewn in Figure 2 a strip of double width and folding
the latter along the centre, the edges being then sewn in order to form the tubes.
In my Provisional Specification I referred to the tubular edges as "loops.'
Although I have described the fabric as having the longitudinal threads at
the central position omitted it is to be understood that the longitudinal threads at
the edges may be omitted instead.
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. A jacket or covering for pneumatic tyres and other articles having curvilinear
surfaces, composed of india rubber or other elastic material lined with or having
inserted therein a fabric having a portion of the threads running longitudinally of
the said fabric omitted, substantially as, and for the purposes, described.
2. A jacket or covering for pneumatic tyres and other articles having curvilinear
surfaces, composed of india rubber or other elastic material lined with or having
inserted therein a fabric having a portion of the longitudinal threads at the
centre of such fabric omitted, substantially as, and for the purpose, described.
J
3. The manufacture and use of coverings for pneumatic tyres or other curvilinear
articles, substantially as hereinbefore described.
