PROVISIONAL SPECIFICATION.
Improvements relating to Pneumatic Tyres for Cycle and other
Vehicle Wheels.
I, HENRY KESTERTON, of 16 Grosvenor Road, Coventry, in the County of
Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention consists of improvements relating to pneumatic tyres for cycle and
other vehicle wheels, my object being to securely fasten the outer protecting cover
around the inner air tube independently of the wheel rim, and to provide a simple
and effective means for preventing rolling or creeping action of a tyre when fixed
in position upon its wheel.
In carrying my invention into effect in one convenient manner, I employ an
ordinary continuous air tube of india-rubber or other suitable material, constructed
in any well-known manner.
The outer protecting sheath or cover of such inner air tube 1 form by a continuous
strip of india-rubber and canvas, or other suitable material, having engaging hooks
or connections formed or attached at its edges. The cover is preferably of
sufficient width to completely embrace the air tube, and for the edges to overlap
before interlocking with each other. Within one edge or at one side of the cover
I insert a gripping strip consisting of vulcanized fibre or other suitable rigid or
non-elastic material, the ends of the strip being caused to overlap each other.
The strip is preferably of the same width as the wheel rim on which the tyre is
to be fixed.
The ordinary air charging valve and connections are attached to the tyre in the
usual manner, and on inflating the inner tube, the outer sheath or cover is expanded
by the internal pressure, and its engaging edges drawn tightly on to each other,
and thus the air tube and the outer cover, with its rigid or inextensible edge as
hereinbefore described, are effectually secured together.
With this method of fastening, the tyre can be inflated when away from the
wheel, the component parts of the complete tyre being effectually secured quite
independently of the wheel rim. When the tyre is inflated after it has been placed
in position on the wheel rim, the pressure on the lower part of the air tube acting
towards the centre of the wheel presses the inextensible edge of the cover firmly to
the wheel rim, and so prevents any creeping or like movement of the tyre relatively
to the wheel. The free overlapping ends of the gripping strip forming the
inextensible edge of the cover permits of circumferential movement, but the

page_text: rigidity of the material prevents any transverse movement or stretching of the
edge.
In the application of my method of preventing any rolling or like movement of the
tyre upon the rim by the action of the pressure on an in-elastic strip, to a tyre of the
single tube type, I attach the in-elastic strip to the under side of the tube in any
convenient manner, causing its ends to overlap each other to permit of circumferential
movement. In this manner I am enabled to prevent rolling or creeping action by the
automatic closing or binding of the strip upon the rim, without the use of cementing
material such as is ordinarily employed.
I adapt my invention to varying forms of tyres for cycle and other vehicle wheels,
making such modifications as may be necessary to suit particular requirements,
without departing from its essential features.

Improvements relating to Pneumatic Tyres for Cycle and other
Vehicle Wheels.
I, HENRY KESTERTON, of 16, Grosvenor Road, Coventry, in the County of Warwick,
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 consists of improvements relating to pneumatic tyres for cycle and
other vehicle wheels, my object being to securely fasten the outer protecting cover
around the inner air tube independently of the wheel rim, and to provide a simple
and effective means for preventing rolling or creeping action of a tyre when fixed in.
position upon its wheel.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to.-
Figures 3 and 4 are transverse sections illustrating two modified methods of
applying my invention.
The same reference letters in the different views indicate the same parts.
In the application of my method of preventing any rolling or like movement of
the tyre upon the rim by the action of the pressure on a gripping strip, to a tyre of
the single tube type, such as shown at Figure 3, I insert the strip C within the
under side of the canvas or protecting material, causing its ends to overlap each
other to permit of circumferential movement, as hereinbefore described. The canvas
or protecting material enclosing the air tube is cut on the bias to permit of the
necessary stretching of the material in order that it may be readily placed on the
wheel rim.
Instead of making the edges of the cover overlap or meet each other, I sometimes
connect or secure them by means of a gripping band formed from a strip of steel
or other suitable material preferably of a trough like section as C, Figure 4,
the turned down edges gripping the cover tightly on to the rim on inflation of
the tyre.
The form of rim shown in the drawings is not essential to the application of my
invention, as my improved tyre can be readily and effectually secured upon any rims
suitable for cycle or other vehicle wheels.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.-
1. The improved pneumatic tyre for cycle and other vehicle wheels consisting of a
continuous inner air tube having an outer covering entirely embracing the same, and
cemented or permanently secured thereto, or having a detachable covering embracing
only the upper or exposed portion of the tyre, in combination with a gripping band
or ring having overlapping ends substantially as hereinbefore described and as
illustrated at Figures 3 and 4 of the accompanying drawings.
