PROVISIONAL SPECIFICATION.
Improvements in Pneumatic and other Flexible Tyres for the Wheels
of Cycles and other Vehicles.
I, JAMES FRANCIS RICHARD WOOD, of 32, Daleview Road, Stamford Hill, in
the County of London, Artist, do hereby declare the nature of this invention to be
as follows:-
My invention relates to improvements in pneumatic and other flexible tyres for
the wheels of cycles and other vehicles.
In carrying my invention into practice I construct a pneumatic tube of india
rubber with a porous, sponge-like or cellular cushion or tread made of vulcanized.
or virgin india rubber, thick enough to prevent. the deepest punctures from the
tyre or cover entering the inflated tube. The inflated tube is protected on its
periphery by the soft rubber and the tyre or
This substantial
cushion or tread has the advantage of retaining to a great extent the
contour of the tyre when somewhat deflated, thus presenting to the road the
minimum proportion of its curved surface, but an ordinary tyre when slightly.
deflated spreads on the road with the weight of the rider and consequently presents
more surface for suction or drag; or I might prefer to fill the tread with horsehair,
asbestos or other light fibrous material or leave it unfilled thus constituting the a
simple air chamber composed of one or more channels, which for all practical
purposes amounts to a section of cushion tyre not requiring inflation superposed as
a tread to the inflated tube.
I also form a pneumatic tube or tyre shaped to admit of being shod with a porous
sponge lile tread placed on the periphery or outside of the inflated tube, and which
has the advantage of being renewable and preventing side-slip as well as preventing
the deepest punctures entering the inflated tube. This tread may be vulcanized on
its periphery.
Also construct a cushion tyre by the said tyre being partially filled with the
porous sponge like or cellular india rubber, either vulcanized or pure.
I also construct a solid tyre by entirely filling the tyre with the porous sponge
like or cellular india rubber.
All tyres of flexible material such as rubber reduce vibration, a potent factor in
exhausting the rider, but when highly inflated this reduction is very slight, but with
this cellular tread or hollow compartment superposed besides avoiding punctures of
the air chamber, makes riding a luxury with a very taut tyre and consequently
more consistant with speed.

I, JAMES FRANCIS RICHARD WOOD, of 32 Daleview Road, Stamford Hill, in
the County of London, Artist, 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 improvements in pneumatic and other flexible tyres for
the wheels of cycles and other vehicles, which are intended to be attached to the
rims of cycle wheels, and other vehicle wheels.
I attain these objects by the methods shown in the accompanying drawing, in
which-
Fig. 1, is a section of a pneumatic tyre with tubes e.
Fig. 2, is a section of a pneumatic tyre with porous or soft rubber b between the
inflated tube c and the outside cover a.
Fig. 3, is a section of a pneumatic tyre with porous or soft rubber on the
outside.
Fig. 4, is a section of a cushion tyre.
Fig. 5 is a section of a solid tyre.
Similar letters refer to similar parts throughout the several views.
In carrying my invention into practice I construct a pneumatic tube c (fitted into
a rim d) of india rubber with a porous, sponge-like or cellular cushion or tread b
made of vulcanized or virgin india rubber, thick enough to prevent the deepest
puncture from the tyre or cover a entering the inflated tube c. The inflated tube c
is protected on its periphery by the soft rubber b and a part of the tyre or cover a
as in Fig. 2. This substantial cushion or tread has the advantage of retaining to a
great extent the contour of the tyre when somewhat deflated, thus presenting to the
road the minimum proportion of its curved surface, but an ordinary tyre when
slightly deflated spreads on the road with the weight of the rider and consequently
presents more surface for suction or drag; or I might prefer to fill the tread with
horsehair, asbestos or other light fibrous material or leave it unfilled thus con-
stituting the tread b a simple air chamber composed of one or more tubes or
channels e as in Fig. 1, which for all practical purposes amounts to a section of
cushion tyre not requiring inflation superposed as a tread b to the inflated tube c.
In Fig. 3, I form a pneumatic tube or tyre e shaped to admit of being shod with
a porous sponge like tread b placed on the periphery or outside of the inflated tube c,
and which has the advantage of being renewable and preventing side-slip as well
as preventing the deepest puncture entering the inflated tube c. This tread may
be vulcanized on its periphery.
In Fig. 4, I construct a cushion tyre by the said tyre a being partially filled with
the porous sponge like or cellular india rubber, either vulcanized or pure.
In Fig. 5, I construct a solid tyre by entirely filling the tyre a with the porous
sponge like or cellular india rubber.
All tyres of flexible material such as rubber reduce vibration, a potent factor in
exhausting the rider, but when highly inflated this reduction is very slight, but
with this cellular tread or hollow compartment superposed besides avoiding
purictures of the air chamber, makes riding a luxury with a very taut tyre
and consequently more consistent with speed.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I hereby declare that
what I claim is :-
1. In tyres, the combination of the tyre a pneumatic tube channels and porous

page_text: sponge like india rubber cushion or tread b, substantially as herein described and
for the purpose specified.
. 2. In tyres, the combination of the tyre or cover a pneumatic tube c and the
tread b, substantially as described.
3. In tyres, the combination of the tyre a air tube c and the cushion or tread b
on the outside, substantially as described.
4. In cushion tyres, the combination of the tyre a and the porous sponge like
india rubber b, substantially as described.
5. In solid tyres, the combination of the tyre a and the porous material b,
substantially as described.
