I, MORLAND MICHOLI. DESSAU, of The Grot, The Green, Ealing, in the County of
Middlesex, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to pneumatic tyres and may be carried out in the following
manner :-
I employ any suitable expansible air-tube with a valve as usual passing through
the rim of the wheel, and I place this air-tube inside a cover which may be made
The cover is
of canvas, special fabric or the like, and covered with rubber or not.
divided longitudinally throughout its inner circumference, the edges being stiffened
or strengthened in any suitable way, preferably by longitudinal or cross wires or
woven wire or the like. Each strengthened edge is divided at one or more
parts.
The edges may or may not be joined together at any necessary parts as by
hooking or other equivalent means, and may be secured to the wheel rim at one
part, preferably by screwing the valve or the valve plate down upon them. Or the
edges of the cover may overlap.
Any suitable section of rim may be employed with these tyres.
The stiffening may be made in or secured to the edges of the cover or may lie
in pockets therein, and the material at or about that part may be compound, one
portion being cut on the bias and the other on the straight.

Improvements in or relating to Pneumatic Tyres.
I, MORLAND MICHOLL Dessau, of 'The Grot, The Green, Ealing, in the County of
Middlesex, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
"
This invention relates to pneumatic tyres and may be carried out in the
following manner :—
•
I employ any suitable expansible air-tube with a valve as usual passing through
the rim of the wheel, and I place this air-tube inside a cover which may be made of
canvas, special fabric or the like, and covered with rubber or not. The cover is
divided longitudinally throughout its inner circumference, the edges being stiffened

woven wire or the like. The strengthening or stiffening of each edge may be
divided at one or more parts:
The edges may or may not be joined together at any necessary parts as by
hooking or other equivalent means, and may be secured to the wheel rim at one
part, preferably by screwing the valve or the valve plate down upon them. Or the
edges of the cover may overlap.
Any suitable section of rim may be employed with these tyres.
The stiffening may be made in or secured to the edges of the cover or may lie in
pockets therein, and the material at or about that part may be compound, one
portion being cut on the bias and the other on the straight.
When the wires or threads are woven upon the cross or the material is cut on
the bias the edges of the tyre will be contractile in their action when the tyre is
inflated, but in other cases, for instance, when the threads are continuous the edges
will be inextensible.
The edges of tyres or tyre-covers, made according to this invention are woven
with thread, wire, cord or the like or a combination of, wire or thread or similar
materials. Long continuous strands, or many short strands may be employed and
may be woven into the fabric of the tyre or cover, or may be formed independently
and subsequently attached to the tyre..
The threads or wires may be so placed as to give the appearance of continuous
lines round the circumference of the tyre or they may have spaces between them
in which cross threads or wires are placed.
The woven edges may have a bead or thickening of suitable material made on or
affixed to them, its object being to press against the rim and give the edge of the
tyre & finished appearance. When a bead is used it may comprise one continuous
band of rubber, shellac or the like or of elastic strand or cloth and may be
moulded so as to have a triangular, semi-circular, or other convenient shape in
cross section.
I am aware that many attempts have been made to construct a fabric which will
contract upon the rim when the tyre is inflated but I am also aware that such
attempts have not as yet been a practical success and have failed to answer the
purpose for which they were intended.
In the accompanying drawings Figures 1-9 are perspective views showing
portions of various forms of tyres or tyre covers all according to this invention.
Figures 10 and 11 show portions of similar tyres having a bead which bears
against the rim.
Like letters indicate like parts throughout the drawings.
A is a portion of a pneumatic tyre cover having wires or threads B woven in
its edges.
In Figure 1 the wires or threads B are arranged circumferentially with spaces
between them in which cross wires are placed. In Figure 2 the wires are
arranged in a crosswise fashion and have short, straight wires between the crosses.
In the tyre illustrated in Figure 3 the wires B are placed continuously round the
circumference. This arrangement gives an inextensible form of cover.
Figure 4 is a view of a similar cover to that illustrated in Figure 3 with the
addition of cross wires above the continuous wires or threads B.
Figure 5 also shows a tyre similar to that illustrated in Figure 3 but which has
two sets of cross wires one over the other.
Figures 6 and 7 illustrate tyre covers in which short lengths of wire are arranged 5
circumferentially on the edges having spaces between them. In Figure 7 the wires
overlap one another.
In Figures 8 and 9 the wires are arranged in the form of Vs.
Figures 10 and 11 show portions of tyre-covers according to this invention
having beads C upon the outside which press upon the edges of the rims D. The 5
beads shown in Figure 10 are triangular in cross section, while those illustrated
in Figure 11 are semicircular.

page_text: It is obvious that many modifications may be made in the form of tyres or tyre
covers as herein described without departing from the spirit of this invention, and
it is to be understood that I do not limit myself to the particular construction
herein illustrated.
.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. A pneumatic tyre or tyre-cover having wires threads or the like such as B
woven in its edges substantially as described.
2. A pneumatic tyre or tyre-cover having wires threads or the like such as B
Figs. 1, 2, 6, 7, 8, 9, 10, & 11, so woven in its edges that it contracts upon the rim
when inflated.
3. A pneumatic tyre or tyre-cover having wires threads or the like such as B
woven in its edges and beads such as C.
4. A pneumatic tyre or tyre-cover having wires threads or the like woven in its
edges and beads such as C which press upon the edges of the rim when the tyre is
inflated substantially as described.
5. A pneumatic tyre or tyre-cover having its edges made by weaving wires
threads or the like together and fixing the woven fabric upon the material forming
the tyre or tyre-cover substantially as described.
6. The pneumatic tyres or tyre-covers substantially as described or illustrated
in Figures 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 10 or 11 of the accompanying
drawings.
