Improvements in Inflatable Tires, and Rims therefor..
We FREDERICK WESTWOOD of 85 Bradford Street Birmingham Managing Director
and WALLACE HENRY PAULL of 52 Goldsmith Road Kings Heath near Birmingham,
Manager, do hereby declare the nature of this invention to be as follows :-
Our invention consists in improved methods of constructing and arranging inflatable
tires, and in special forms of pads and coverings for the bed of the rim.
In constructing a tire according to our-invention, we may build up an arch shaped
or split tubular tire, which may be formed of canvas, cloth, threads, or other suitable
restraining material provided with the usual layer of rubber or other suitable wearing
material on the outer surface, and covered on the inside and around the edges of the
tire with a layer of rubber or equivalent air-proof substance. We may also embody
within the tire various methods of attaching the said tire to the rim such as the
methods shown in Patents No. 22000 and 22001/1893, 1225/94, 6759/94, 25032/94,
2401/95, but we do not restrict ourselves to these methods of attachments. We may
use other methods in which inextensible bands or wires are provided in the tire, or
wires or bands may be used which are not necessarily attached to the tire, and such
wires or bands may also be provided with hooks, screws, bolts, or other couplings, or
they may in certain cases not be continuous. We may use such a tire and attachment with
any suitable form of rim. The rim being provided with a flexible and air-proof bed.
The tire when placed upon such a rim or bed making an air-tight joint with the same,
enabling the tire to be inflated. In some cases we may combine the flexible bed, or
its equivalent, with the tire; in others we may discard the flexible bed and merely
provide for making the rim air-tight by means of cement etc.
For inflating our improved forms of tires we may use any suitable valve applied
to the rim or tire in any convenient manner, or we may do without the usual valve
utilizing the flexible bed of the rim as a valve, providing merely a small hole in the
rim and an inflating tube attached to the pump capable of being inserted through
the rim pad, with or without a cap for closing the inflating aperture.
Our tire may be repaired on the inside by removing it wholly or partially from the
rim, or may be repaired from the outside by injecting solution, or inserting rubber
cord, plugs etc.
According to one method we construct our tire of fabric and rubber in combination
with one of the contractile methods of attachment described in Patents No. 1225/94
and 6759/94. The inside and edges of the tire are covered with rubber. A flexible and
air-proof rubber pad is then placed in the bed of the rim. The tire is then placed in
the rim on top of the said flexible pad, the edges of the tire sinking into the pad and
making a sufficiently air-tight joint with the pad to allow of inflating the tire. As the
process of inflation proceeds the contracting of the edges of the tire increases the
security of the air-retaining joint and also fixes the tire to the rim.

page_text: We, FREDERICK WESTWOOD, and WALLACE HENRY PAULL, both of 85 Bradford
Street, in the City of Birmingham, Manufacturers, 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 :-
Our invention consists of improved methods of constructing and arranging inflatable
tires and in special forms of pads and coverings for the bed of the rim.
In constructing a tire according to our invention, we build up an arch shaped or
split tubular tire which may be formed of canvas, cloth, threads, or other suitable
restraining material provided with the usual layer of rubber or other suitable wearing
material on the outer surface, and covered on the inside and around the edges of the
tire, with a layer of rubber or equivalent air proof substance. We may also embody
within the tire various methods of attaching the said tire to the rim, such as the
methods shown in Patent Specifications Nos. 22000 and 22001 of 1893; 1225 of 1894;
6759 of 1894; 25032 of 1894 and 2401 of 1895, but, we do not restrict ourselves to
these methods of attachments. We may use other methods in which inextensible
bands or wires are provided in the tire, or wires or bands may be used which are
not, necessarily, attached to the tire, and such wires or bands may also be provided
with hooks, screws, bolts, or other couplings, or they may in certain cases not be
continuous or endless bands.
We may use such a tire and attachment in combination with any suitable form of
rim. The rim being provided with a flexible and air proof bed. The tire, when placed
upon such a rim or bed making an air tight joint with the same, enabling the tire to
be inflated. In some cases we may combine the flexible bed or its equivalent, with
the tire, in others we may discard the flexible bed, and merely provide for making the
rim air tight by means of cement or the like.
For inflating our improved forms of tires, we may use any suitable valve, applied to
the rim or tire in any convenient manner, or we may do without the usual valve
utilising the flexible bed of the rim as a valve, providing merely a small hole in the
rim and an inflating tube attached to the pump capable of being inserted through
the rim pad, with or without a cap for closing the inflating aperture.
Our tire can be repaired on the inside by removing it wholly or partially from
the rim, or may be repaired from the outside by injecting solution, or inserting rubber
cord plugs or the like.
According to one method, we construct our tire of fabric and rubber, in'
combination with one of the contractile methods of attachment described in Patent
Specifications Nos. 1225 of 1894 and 6759 of 1894. The inside and edges of the
tire are covered with rubber. A flexible and air proof rubber pad is then placed
in the bed of the rim.
The tire is then placed in the rim on top of the said flexible pad, the edges of the
tire sinking into the pad and making a sufficiently air tight joint with the same to
allow of inflating the tire. As the process of inflation proceeds the contracting of
the edges of the tire increases the security of the air retaining joint and also fixes the
tire to the rim.
In the accompanying sheet of explanatory drawings or diagrams to be hereinafter
referred to
Figure 1 is a section of a tire constructed in accordance with our invention, detached
from its wheel rim.
Figure 2 is a section of the hollow rubber rim pad, and Figure 3 a similar view of
one form of wheel rim suitable for the reception of our tire.

page_text: Figure 4 is a sectional view of the complete tire in position on the wheel rim.
The tire is constructed as hereinbefore described, and comprises an outer wearing
surface A attached to a restraining fabric B which is covered on the inside with an
air proof layer of rubber C, such inner layer of rubber being also passed round the
edges D of the tire as illustrated at Figure 1. It will be understood that the three
parts, namely, the outer wearing surface A, the restraining fabric B and the inner
layer C are all united or consolidated together.
The edges of the tire are secured to the rim by any of the methods described
in the Patent Specifications hereinbefore referred to, or in any other convenient
manner.
The pad E consists of a continuous hollow strip or ring of rubber of sufficient size
to permit of its being sprung over the rim F and to bed on the same as illustrated at
Figure 4.
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. The construction of an inflatable tire substantially as described.
2. In inflatable tires the use of a hollow rim pad substantially as and for the
purposes described.
3. An inflatable tire comprising an arched-shaped outer portion covered on the inside
and around the edges with rubber and carrying within its edges the means of
attachment, in combination with a suitable rim and an interposing air proof pad
with which the edges of the outer portion make an air tight joint, substantially as
described.
4. The combination of parts forming the improved inflatable tire substantially
as described and as illustrated.
