PROVISIONAL SPECIFICATION.
Improvements in and connected with Pneumatic Tyres.
We, JOSEPH MOSELEY, Indiarubber Manufacturer, and BENJAMIN BLUND-
STONE, Works Manager, both of the Chapelfield Works, Ardwick, Manchester in
the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
.
This invention relates to pneumatic or inflated tyres in which the air-containing.
tube is included within a canvas or similar tube or pocket. In such tyres it is
frequently necessary to examine and repair the air-containing tube or the valve
through which it is inflated for which purpose the pocket has to be opened and
afterwards stitched or otherwise secured.
The object of this invention is to avoid the necessity for the stitching or patching
of the pocket after examination or repair of the air tube or valve, and to make
that part of the pocket which has to be opened, stronger rather than weaker than
before.
For the purpose of our invention we arrange one or more lengths of canvas or
textile tubing around the pocket, and draw this length or one of them over the
opening which has been made in the pocket, after the air tube or valve has been
examined or repaired. This outer short tube over the pocket effectively closes the
opening and permits the tube to be safely inflated. In the case of the short tube
arranged to protect the opening through which the valve passes, a hole is made in
it for the passage of the valve so that when the air tube is deflated, the valve may
be readily withdrawn.
One of the short lengths of outer tube may if desired be employed to cover the
ends of the pocket to strengthen their junction.

COMPLETE SPECIFICATION.
Improvements in and connected with Pneumatic Tyres.
We, JOSEPH MOSELEY, Indiarubber Manufacturer, and BENJAMIN BLUND-
STONE, Works Manager both of the Chapelfield Works, Ardwick, Manchester in
the County of Lancaster, 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 pneumatic or inflated tyres in which the air-containing
tube is included within a canvas or similar tube or pocket. In such tyres it is
frequently necessary to examine and repair the air-containing tube or the valve
through which it is inflated, for which purpose the pocket has to be opened and
afterwards stitched or otherwise secured.
The object of this invention is to avoid the necessity for the stitching or patching
of the pocket after examination or repair of the air tube or of the valve, and to
make that part of the pocket which may have been opened, stronger rather than
weaker than before.
For the purpose of our invention, we arrange one or more lengths, hereinafter
called "sleeves" of canvas or textile tubing around the pocket, and draw this
sleeve, or one of the sleeves over the opening which has been made in the pocket,
after the air tube or valve has been examined or repaired. This sleeve over the

page_text: pocket effectively closes the opening, and permits the tube to be safely inflated.
In the case of the sleeve arranged to protect the opening through which the valve
passes, a hole is made in it for the passage of the valve, so that when the air tube
is deflated the valve may be readily withdrawn.
One of the sleeves may, if desired, be employed to cover the ends of the pocket
to strengthen their junction.
We will more particularly describe our said invention with reference to the
accompanying drawings, in which
Figure 1 is an elevation of a short length of air tube A with the sleeve B
covering the opening which has been made in the canvas pocket C, for the purpose
of repairing the air tube.
Figure 2 is a similar elevation shewing the sleeve drawn back, exposing an
opening in the pocket through which the air tube is accessible for repairs.
Figure 3 is a view similar to Figure 2, but shewing that part of the air tube to
which the valve is attached drawn through the opening for examination or repair.
Figure 4 shews the sleeve B restored to its working position. It will be
observed that in the case of the sleeve B which has to cover the part of the tyre
in which the valve is situated, an opening is made at E, for the passage of the
valve stem.
Figure 5 is an elevation of a complete tyre having thereon four of the sleeves B.
In general practice for endless tubes, this will be found to be a convenient number,
but a lesser number may be employed if desired, particularly in the case of tyres of
comparatively large diameter. In the event of non-continuous tubes which may be
withdrawn from the pocket when deflated, one of the sleeves B at the valve, with or
without another at about the opposite diameter of the tyre, may suffice.
In most cases, since the deflated tyre may be drawn through the pocket for a
considerable distance, instead of opening the pocket at the precise. spot where:
repairs to the air tube are required, it will suffice to have perinanent openings D at
equal distances apart, each of which is normally covered and protected by one of
the short sleeves B. Thus, when it is necessary to mend the air tube the tube is
deflated, the nearest sleeve is drawn back, and the air tube is pulled through the
opening until the part to be repaired is exposed, as shewn at F, Figure 5. If the
permanent openings D are employed, their edges may be bound, or be protected by
tapes solutioned or otherwise secured thereon.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is..to be performed, we declare that what we
claim is :-
1. In a pneumatic or inflatible tyre, the combination and arrangement with an
air tube and an enclosing pocket, of one or more sleeves, substantially as and for
the purpose herein before described and as illustrated by the accompanying
drawings.
2. The hereinbefore described means for covering and protecting an opening
made in the pocket of a pneumatic or inflatible tyre, substantially as hereinbefore
described and as illustrated by the accompanying drawings.
