PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tyres.
We, JOSEPH MOSELEY, Indiarubber Manufacturer, and BENJAMIN BLUNDSTONE,
Manager, both of the Chapelfield Works, Ardwick, Manchester, in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:
--
This invention relates to pneumatic or inflated tyres for the wheels of velocipedes
and other vehicles, and its object is to enable the tyres to be firmly secured to the
rims of the wheels by simple means such as will allow ready access to the air
containing tubes for repairs and other purposes, and permit the tyres to be quickly
made good thereafter without special appliances of any kind.
In the construction of a tyre according to these improvements, we arrange near
or at each edge of the outer part of the tyre, commonly known as the tread, an
endless band hank or cord, which is formed of linen or other yarn, of thin metallic
wire, or of other analogous inextensible material, wound wrapped or laid around
and around a suitable support or former to produce a ring of the required diameter,
until a sufficient quantity to form the endless band has been so used. It may be
wound lapped or laid upon the part of the tread which it is to occupy in use, or it
may be independently formed and arranged thereon afterwards. The various turns
or strands of the endless band may or may not be separately or collectively
charged or coated with indiarubber indiarubber compound or other cementitious
or protective material, and they may be secured upon the tread by any convenient.
means.
The tyre is used with a hollowed or channelled rim by preference, and the edges
of the tread beyond the endless bands may or may not be enlarged or thickened,
and may or may not be turned over, according to the method of construction of
the tyre which it is preferred to adopt.
If the edges of the tread extend beyond the endless bands, they may meet or
overlap each other on the rim, and form a better and greater seating for the
air tube.
If it be required to inspect or repair the air tube, it is only necessary to deflate
the tyre, when any part of the tread may be removed, or the whole tyrè may be
nstantly taken off the rim, and be easily replaced.

Improvements in Pneumatic Tyres.
We, JOSEPH MOSELEY, Indiarubber Manufacturer, and BENJAMIN BLUNDSTONE,
Manager, both of the Chapelfield Works, Ardwick, Manchester, in the County of
Lancaster, 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 pneumatic or inflated tyres for the wheels of velocipedes
and other vehicles and its object is to enable the tyres to be firmly secured to the
rims of the wheels by simple means such as will allow ready access to the air
containing tubes for repairs and for other purposes and permit the tyres to be
quickly made good thereafter without special appliances of any kind.
In the construction of a tyre according to these improvements we arrange at or
[Price 8d.1

page_text: near each edge of the outer part of the tyre commonly known as the cover or tread,
an endless band hank or cord which is preferably formed of thin metallic wire or
of other analogous inextensible or comparatively inextensible material, wound
lapped or laid around and around a suitable support mandrel or former to produce
an endless ring of the required diameter, until a sufficient number of turns have
been taken to form the required endless band. The yarn or like material may be
wound lapped or laid upon the part of the tread or cover which it is to occupy in
use, or it may be independently formed and arranged thereon afterwards. The
various turns or strands of the endless band may or may not be separately or
collectively charged or coated with indiarubber indiarubber compound or other
cementitious or protective material, and it may be secured upon the tread by any
convenient means.
The tyre is used with a hollowed or channelled rim by preference, and the edges
of the tread or cover beyond the endless bands may or may not be enlarged or
thickened, and may or may not be turned over, according to the method of
construction of the tyre which it is preferred to adopt.
If the edges of the tread or cover extend beyond the endless bands, they may or
may not overlap each other on the rim, and form a better and larger seating for the
air tube.
If it be required to inspect or repair the air tube it is only necessary to deflate
the tyre, when any part of the tread may be removed, or the whole tyre may be
instantly taken off the rim and be quickly and easily replaced.
We will describe in what manner our invention may be carried into practical
effect with reference to the accompanying drawings in which-
Figure 1 represents a tyre cover or tread in the first stage of construction, and
Figure 2 is a second stage. In each of these figures a portion of the cover is
represented as being removed for the purpose of shewing the construction more
clearly.
Figure 3 shews in cross section the construction illustrated by Figures 1 and 2.
Figure 4 represents in cross section a modification in the construction.
In each of the wheels A A are the endless bands B the tread or cover of the
tyre, and C the edges of the tread which extend beyond the endless band.
As illustrated by Figures 1 and 2 the tread or cover is constructed in the usual
U-form and the endless bands A consisting of several turns of yarn or the like
are arranged thereon concentrically with and at the proper distance from the
edges, (Figure 1). The edges are then turned over the endless bands and cemented
down as shewn in Figure 2 where the endless bands are supposed to be outside the
cover but they may of course be arranged inside when the edges also would be
folded inside over the bands. Alternatively the endless bands may be cemented in
rings of canvas and these in turn be cemented to the tread, or other means of a
similar character may be employed for the purpose of securing the bands to the
treads or covers. It is preferred that they should be so secured before vulcanisation
but they may be attached to the tread after this process.
Should the edges or one edge of the tread or cover be made of sufficient width,
as shewn by Figure 4, these edges are arranged to lay or overlay each other on the
rim between the endless bands, and under the air tube.
The method of applying the tyres in which these improvements are embodied to
the rim of the wheel does not differ from methods already in common practice.
A considerable advantage attending the use of the endless bands constructed as
hereinbefore described is that they lie more snugly and closely in their channels and
thus prevent the admission of mud and dust to the interior of the rim where it is
now apt to accumulate between the rim and the air tube. Its flexibility also permits
it to be much more readily arranged and removed than at present is the case with
similar means for connecting tyres to rims.
We are aware that endless wires consisting of a single wire with its ends brazed
together or connected by a nut or the like have already been employed, but they
are objectionable on account of their comparatively great rigidity and greater

page_text: liability to break in use. We are also aware that wires or cords have been
employed for the purpose of securing solid tyres upon their rims and we therefore
desire it to be understood that we make no claim to such use.
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-
In combination with the tread or cover of a pneumatic tyre, two endless bands.
each consisting of a number of turns of yarn or the like substantially as and for
the purpose herein before described and as illustrated by the accompanying
drawings.
