PROVISIONAL SPECIFICATION.
Improvements in and relating to Pneumatic Tyres.
I, WILLIAM YATES LAMBERT, of Talbot House, Wisewood, Sheffield, in the
West Riding of Yorkshire, Manager of Works, do hereby declare the nature of
this invention to be as follows:-
This invention relates to an improved construction of pneumatic tyre, and it has
for its object attaching the cover to the wheel rim in a simple and convenient
manner having regard to the necessity of easy access to the air tube.
To this end my invention consists essentially of an outer cover made of rubber or
other suitable material and reinforced by canvas or other fabric in the well-known
manner, the said cover being a divided one and having beads or enlargements on
its edges. The rim may be either of the solid or hollow type and either of a flat-
groove section or of a crescent section. The air tube is made of rubber in the
well-known manner, and is provided with any suitable form of valve for inflation.
Formed on or attached to the inner side of the air tube is a band or strip of canvas
or other suitable fabric having inextensible edges. The width of the band or strip
being such that its inextensible edges lie above or outside the beaded edges of the
cover and thereby throttle or restrict them within the wheel rim until they are
pushed aside to free the edges of the cover.
A convenient method of forming the inextensible edges in the fabric band or
strip is to form pockets in the said edges and to place hoops of wire or other
suitable material in the pockets.

Improvements in and relating to Pneumatic Tyres.
1, WILLIAM YATES LAMBERT, of Talbot House, Wisewood, Sheffield, in the
West Riding of Yorkshire, Manager of Works, 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 an improved construction of pneumatic tyre, and it has
for its object attaching the cover to the wheel rim in a simple and convenient
manner having regard to the necessity of easy access to the air tube.
To this end my invention consists essentially of an outer cover made of rubber
or other suitable material and reinforced by canvas or other fabric in the well-
known manner, the said cover being a divided one and having beads or enlargements
on its edges; of an air tube made of rubber in the well-known manner and provided
with any suitable form of valve for inflation and deflation; of a longitudinal band or
strip of canvas or other suitable fabric having inextensible edges formed on or
attached to the air tube, the width of the band or strip being such that its
inextensible edges lie above or outside the beaded edges of the cover.

page_text: The rim may be either of the solid or hollow type and may be of the ordinary
crescent section, of the flat groove section or of any other section found
suitable.
In the accompanying drawing which illustrates this invention :-
Figures 1, 2 and 3 are views in transverse section showing-by way of example-
some methods of carrying the invention into practice, and
Figure 4 is a view in transverse section of the air tube and band.
Throughout the views similar parts are marked with like letters of reference.
The outer cover A is made of rubber or other suitable material reinforced with
canvas or other suitable fabric in the well-known manner, and its edges are formed
with beads or enlargements a a of any suitable shape. The air tube B is made of.
rubber in the well-known manner and is provided with any suitable type of valve
for inflation and deflation. Attached to the air tube B is a longitudinal band or
strip C of canvas or other suitable material, the edges c c of the said band or strip
being made inextensible in any suitable manner, such for instance as the combination:
with, or insertion in, of inextensible bands of wire or other suitable material. The
rim D may be of any desired shape in cross section, so that it is adapted to receive
the enlarged or beaded edges a a of the cover A. The width of the band C is such
that its inextensible edges c c lie over or outside the enlarged or beaded edges a a
of the cover and thereby throttle or restrict the said edges within the wheel rim
until the inextensible edges of the band are pushed aside to free the edges of the
cover which can only be done when the air tube is deflated.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
(1.) The improvements in pneumatic tyres substantially as herein before described
and illustrated by the accompanying drawing.
.
(2.) In a pneumatic tyre, the combination with an air tube, of a band or strip
having inextensible edges in the manner and for the purpose set forth.
(3) In a pneumatic tyre the combination with a wheel rim such as D, of a cover
such as A having beaded or enlarged edges a a, of an air tube such as B, and of a
band or strip such as C with inextensible edges c c either formed on or fixed to the
underside of the air tube, as and for the purpose set forth.
Dated this 24th day of December 1895.
