Improvements in or relating to Wheel Tyres.
We, CHARLES ERNEST SQUIER, of 203, Upper Thames Street, in the City of
London, Printer, and FRANCIS WINDILAM, of 73, Queen Victoria Street, in the City
of London, Engineer, 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
manufacture.
relates to wheel tyres, preferably pneumatic, and their
In carrying out the invention we employ any, suitable flexible backing, canvas
for example, and to this we secure by stitching sections of leather or similar
material. Each section is of a suitable thickness, and may be cut out of leather
scrap, and stitched in the following manner.
It is not desirable that the stitches should come through from the outside as
they would then be worn through, and the sections might then escape from the
backing. They are stitched from the side angularly through the canvas. This
provides the necessary adhesion and forms an exceedingly flexible tyre, the close
contact of the sections being generally sufficient to prevent the entrance of wet or
dirt. If desired separating plates of metal or any other suitable material-india-
rubber for instance-may be employed between the sections, and if desired
cemented to them or the sections may be further secured together with flexible
or elastic composition; generally, however, we do not find this necessary.
The tyre may be secured upon the wheel in any suitable manner the fastening
not forming any portion of the present invention."
In the accompanying drawings
Figure 1 is a perspective view of a short length of the improved tyre cover.
Figure 2 is a longitudinal central section of the same on the line 2-2 of Fig. 1.
Figure 3 is a perspective view of a single detached arched section showing one
of the laminae.
Like letters indicate like parts throughout the drawings.
A flexible strip A of length and width sufficient to form a tyre cover has sewn
to it a series of arch-shaped sections B of leather or other material. Each section B
is formed of suitable thickness about its centre being gradually thinned away
towards its ends so as to have the appearance of a crescent. These sections are
sewn to the backing A not only at their ends as at B¹, but also at their centres by
stitches C which pass not directly through each section from the tread side but
in a diagonal manner through the side of each section and into the flexible
backing as shown in Figure 2.
It is important that the sections should be sewn to the backing at their
centres as well as at their edges as they are thereby prevented from rising clear of
the backing when in use, or becoming detached when damaged, while the diagonal
stitching at the centre avoids the danger of the threads being chafed by wear as
would be the case if they passed through the tread..
As an additional precaution against wear small metal plates D may be arranged

page_text: between the sections, being placed edgewise as shown in Figure 3. The con-
tiguous faces of the sections B may be, if desired, recessed in order to accommodate
these plates, and the latter may be secured or not either to the sections or to the
backing as found convenient.
The flexible backing A may be provided with beads, wires, or other devices at
its edges, for attaching it to and retaining it on the wheel rim.
If desired the flexible backing A may be lined with some suitable material to
prevent chafing of the air tube if such is employed by the stitches where they
appear on the inner side of the backing. If preferred solution or cement may be
employed as an additional means of attaching the sections to the backing.
Although as aforesaid the invention is preferably applied to tyres which are
pneumatic it is applicable to tyres expansible by means of internal springs or other
elastic filling.
Having now particularly described and ascertained the nature, of the said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a tyre the employment substantially as described of arched sections such
as B sewn to a flexible backing.
2. In a tyre the combination with a flexible backing of arched sections such
as B sewn to the backing as at B and C substantially as described.
3. In a tyre the combination with a flexible backing of arched sections such as B
sewn to the backing and plates D) between the sections substantially as described.
4. The complete tyre substantially as described or illustrated in the accompany-
ing drawings.
