Improvements in and connected with Pneumatic Tyres for Cycles
and other Vehicles.
I, ALEXANDER BLACK, of 59 North Frederick Street, Glasgow, in the County
of Lanark, Scotland, Tyre Manufacturer, do hereby declare the nature of this
invention to be as follows:-
11
This improvement relates to the lining which prevents the rubber from expanding
when the tyre is being inflated.
In carrying out my invention, I use flax, jute, cotton, hemp, or any other suitable
fibre, in the raw hackled state.
For a detachable tyre, or one with a separate air-tube, I line the outer rubber
cover, that protects the air-tube, with the aforesaid fibre.
For a single-tube tyre, or one on the hosepipe principle, I spread the fibre
between the layers of rubber, during the process of manufacture.
There may be one or more layers of fibre, and when more than one layer, they
may be spread at different angles.
For example:-One layer may be laid or spread latitudinally, or in other words
at right angles to the edge of the rim.
Again, a layer may be added longitudinally, or parallel to the edge of the rim.
Again, a layer may be added at an angle of about 45° to the one already spread
latitudinally.
Again, two layers may be added at about right angles to one another, and at an
angle of about 45° to the one already spread latitudinally.
Again, two layers may be spread at about right angles to one another, and at
an angle of about 45° to the edge of the rim.
The fibre may be combed in such a manner, that, for example, in a cover with
the fibres spread latitudinally, the rubber will be free to expand longitudinally.
In a modification, I may use the fibre in combination with a thin layer of cloth.

I, ALEXANDER BLACK, of 59 North Frederick Street, Glasgow, in the County
of Lanark, Scotland, 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:-
This invention relates to the lining of pneumatic tyres for cycles and other
vehicles, and has for its object to prevent the rubber from expanding when the
tyre is being inflated. To that end I line the inner surface of the outer rubber
cover when the tyre has a separate air tube with flax, jute, cotton, hemp or other
[Price 8d1

page_text: fibre in the raw hackled state, or when theityre is composed of a single air tube on
the hose-pipe principle I spread the fibre between the layers of rubber during the
process of manufacture.
In either case more than one layer of fibre may be used
and these layers may be spread at different angles.
The invention is illustrated by the accompanying drawings, Figs. 1 to 6 being
part vertical sections, and 'Figs. 7 and 8 cross sections of Figs. 3 and 6 shewing
tyres constructed.under different imodifications in accordance with my invention.
Fig. 1 is a vertical section of a tyre for use with a separate air tube and shewing
the fibre spread at right angles to the rim of the tyre, the purpose being to prevent
the rubber cover from expanding laterally and Fig. 2 shews a similar tyre having
a second layer of fibre spread at an angle of 45° to the layer already flaid.
Figure 3 shews a tyre in which the fibre is spread both longitudinal and at
right angles to the edge of the rim which prevents the cover from expanding
longitudinally, or daterally.
Figure 4 shews a tyre having two layers of fibre spread at right angles to each
other and about an angle of 45° to the edge of the rim, and Fig. 5.shews a tyre
so made.but with an additional layer laid laterally, in both cases the tyre being
thereby prevented from expanding either longitudinally or laterally.
Fig. 6.shews a tyre.composed of a single air tube in which the dayers of fibre
have been spread between the layers of rubber in the process of manufacture.
Fig. 7 is a cross section of .Figure 3.shewing the fibre spread longitudinally on
the inner surface of the tyre,.and Fig. 8 is a cross-section.of Figure 6 shewing.the
tyre.constructed of alternate layers of rubber.and.fibre.
As an alternative I.mayause.thetfibre in its.raw hackled state in combination with
a thin layer of .cloth.
For convenience in applying the fibre to the tyre or tyre.cover and for maintaining
it in the form of a flattened .band L.may .brush it.over with rubber solution on tone
or both sides.
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 :-
A tyre or tyre cover composed of rubber or rubber compounds lined with
combed.or.hackled fibre.substantially as and for the purpose-set forth.
