Improvements relating to Pneumatic Tyres, and to Means for
Repairing the same when Punctured.
1, DAVID YOUNG, Patent Agent, of the Firm of D. Young & Co. of
11 and 12 Southampton Buildings, London, W.C., do hereby declare the nature
of this invention to be as follows:-
My invention relates to improvements 10 pneumatic tires and to means for
epaning punctures therein, and comprises a slack patching web a11anged within
the tire and normally maintained adjacent to the base of the tire, and also held
against accidental lateral displacement, by means of a flexible and elastic attaching
strip arranged longitudinally within the tire and secured at intervals to the inner
wall of the tire and to the longitudinal middle line of the patching web.
The
By such arrangement, the patching web will be fice and unattached along its
edges, aud at the same time will be free to be picked up at any point or points
along its length. The patching web may be single or double, but in either case,
the means for attaching it will be found both economical and convenient.
attaching strip thus provided, is attached at intervals to the patching web along a
line between the edges of the latter, and said strip is also attached at intervals to
the inner wall of the tue at the base side of the latter, it being observed that the
points of attachment between the tire and strip, alternate in point of position with
the points at which the strip is attached to the patching web
When a puncture
occurs in the tire, cement can be introduced through the puncture, and by
depressing the punctured portion upon the patching web, the two will unite, and
upon inflating the tire, a portion of the patching web will be picked up and
remain in such condition. The inflation of the the will not force away the
portion of the patching web which is thus sealed to the tire, since such spaces as
may exist at opposite sides of the raised portion of the patching web will be in
open communication with one another
The patching web can be thus arranged within an air-tube which is temporarily
confined in a sheath or casing, and it can also be employed in a pneumatic tire
constructed without a removable air-tube.

page_text: Improvements relating to Pneumatic Tyres, and to Means for
Repairing the same when Punctured.
1, DAVID YOUNG, Patent Agent, of the Firm of D Young & Co. of
11 and 12 Southampton Buildings, London, W.C, 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 improvements in pneumatic tyres and to means for
repairing punctures therein, and comprises a construction of pneumatic fue m
which a slack patching web is confined within the annular air-chamber of the tire
and normally maintained away from the tread portion thereof, so that while it may
escape injury should the tread of the the be punctured, it can be picked up at any
point along its length and cemented to a punctmed portion of the tire as a means
for closing the same.
In a pneumatic tile characterized by the invention, the patching web is normally
maintained adjacent to the base of the tire and held against accidental lateral
displacement by means of a flexible and clastic attaching strip aanged
longitudinally within the tire and secured at intervals to the innct wall of the tire
and to the patching web in which way the patching web whether single or double
can be maintamed in proper elative position by a single attaching band or stip
and at the same time, the patching web will be left exceedingly fice to be picked
up at any point along its length.
In the accompanying drawings,
Figure 1 is a cross section through a pneumatic tire embodying the invention,
said view also including a portion of the wheel-rim
Figue 2 is a hike section though the inner air-tube arranged upon a maudi el

air-tube so as to bring the pitching web within the same
Ligure 3 is a bottom plan view of the patching web and the attaching stip.
Figure 4 is a section taken longitudinally through a portion of the pneumatic
tue and illustrates the patching web picked up and cemented to a punctured portion
of the tne.
Figure 5 is a section taken tiansversely through the au-tube and patching web.
Figure 6 is a cross section taken through the tube of Fig. and illustrates
the inner an-tube turned inside out so as to bring the patching web within
the same
A indicates the sheath and B denotes the inner au-tube of a double tube
pneumatic tile. The patching web C, is concentric with and pormally adjacent to the
inner wall of the base portion of the tire, as illustrated in Fig. 1 in which the base
of the tire is seated upon the wheel-rim D The longitudinally arranged attaching
stap is attached at intervals to the patching web along a line between the edge
portions of the patching web The said attaching stup is also secured at intervals
to the inner wall of the base of the tue, it being observed that the points of
attachment between the tue and strip alternate with the points of attachment
between the strip and the patching web, whereby the latter can be picked up at
any point along its length as indicated in Fig. 4.
When the patching web is picked up and cemented to the tread of the tire as in
Fig. 4, an equilibrium of air pressure will be established at opposite sides of all
of the raised portion of the web excepting the part thereof which is duectly united
to the punctured portion of the tire. The patching web and attaching strip can be
in one or more lengths, the simpler way being however, to form each of a single

page_text: length of material or, if desired, the attaching strip can be in sections regardless
of the length of the patching web
The invention is also obviously applicable to a hose-pipe or one tube tire.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent I declare that what I claim is .-
1. A pneumatic the provided with an internally arranged patching web and a
longitudinally arranged attaching stip connecting the patching web with the tire,
substantially as described.
2. A pueumatic the provided with an internally arranged patching web normally
away from the tread of the tue and a longitudinally arranged elastic attaching
strip secured at intervals to the patching web and to the inner wall o
the tire,
substantially as described.
3. A pneumatic tire provided with an internally arranged patching web C and
an elastic attaching strip attached at intervals to the middle of the patching web
and to the inner wall of the tire, substantially as described.
