PROVISIONAL SPECIFICATION.
An Improvement in or connected with Tyres for Bicycle, Tricycle,
or other Road Vehicle Wheels.
SYDNEY LEE of 9 Furnival Street, Holborn London, Auctioneer and JAMES
RICHARD TRIGWELL of 146 Brixton Hill, Surrey Cycle Manufacturer do hereby
declare the nature of this invention to be as follows:-
Hollow rubber tyres inflated by means of air or gas and commonly known as
pneumatic tyres are admitted to be particularly liable to puncture by nails, pieces
of glass, thorns, pins and other sharp objects, that render the tyres temporarily
useless owing to the escape of the air or gas. Our invention is designed to provide
a means of protecting these tyres from puncture and also to prevent their side
slipping upon damp or greasy roads or tracks. In carrying out our invention we
provide a strip of thin leather or other material preferably from one to one and a
half inches in width. By rollers or other mechanical means we make this strip
into such a shape that it will closely fit the outer covering of the tyre and also
the curve and by joining the ends, which may be lapped, stitched, rivetted,
solutioned or otherwise joined, it forms a round band. This round band may be
shaped according to the form of the exterior covering of the pneumatic tyre upon
which it is desired to place it.
To fix the band we place it round the exterior of a pneumatic tyred wheel when
deflated or partially so.
When the tyre is inflated, the air pressing the exterior of the pneumatic tyre
into the shaped band will hold the said band into firm position which will form &
protection against puncture and side slipping.

COMPLETE SPECIFICATION.
An Improvement in or connected with Tyres for Bicycle, Tricycle,
or other Road Vehicle Wheels.
We, SYDNEY LEE of 9 Furnival Street, Holborn, London, Auctioneer, and
JAMES RICHARD TRIGWELL. of 146 Brixton Hill, Surrey, Cycle Manufacturer,
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 :-
Hollow rubber tyres inflated by means of air or gas and commonly known as
pneumatic tyres are admitted to be particularly liable to puncture by nails, pieces
of glass, thorns, pins and other sharp objects, that render the tyres temporarily
useless owing to the escape of the air or gas. Our invention is designed to provide
a means of protecting these tyres from puucture and also to prevent their side
slipping upon damp or greasy roads or tracks. In carrying out our invention we
provide a strip of thin leather or other material preferably from one to one and a
half inches in width. By rollers or other inechanical means we make this strip into
such a shape that it will closely fit the outer covering of the tyre and also the
го.

page_text: curve and by joining the ends, which may be lapped, stitched, rivetted, solutioned,
or otherwise joined, it forms a round band. This round band may be shaped
according to the form of the exterior covering of the pneumatic tyre upon which
it is desired to place it. To fix the band we place it round the exterior of a
pneumatic tyred wheel when deflated or partially so. When the tyre is inflated
the air pressing the exterior of the pneumatic tyre into the shaped band will
firmly hold the said band which will form a protection against punctures and side
slipping.
In the accompanying drawings:
-
Figure 1 is a cross section of a portion of a pneumatic tyre provided with this
improved covering, and
Figure 2 is a cross section supposed to represent the upper and lower portions
of a tyre when cut through vertically, the intermediate part being broken away.
In these views A represents the pneumatic tyre whether a "solid wall" tyre as
in Figure 1 or an air tube and cover as in Figure 2, and B the strip of leather or
other material which whether by reason of the curve imparted to it by the rollers,
or by its pliancy, or both, follows on its inner face, as shown, the curve of the
tyre; the shape of the outer face of B is not of special importance and may be
curved or flat as may be desired. In Figure 1 a solid strip of leather is indicated
while in Figure 2 a double thickness of canvas G, which may be woven as a tube
or be separate pieces placed one upon the other, and surmounted by the leather B,
is shown. Any desired number of thicknesses may be. employed in the bands B
or G.
In both cases the protecting strip closely follows the curve of the tyre. It
will be seen that the distance from the edge C of the strip B at the top of Figure 2
to the corresponding part C of the strip upon the opposite side of the wheel at the
bottom of Figure 2 is less than the distance from the point D to the corresponding
point D upon the opposite side of the wheel, and consequently the strip being as
previously explained an endless band is firmly retained upon the tyre, as the
smaller diameter C cannot pass over the larger diameter D. No solution or other
means of fastening is required for this band.
Where the material-canvas or rubber for example-is of such a nature that it
will not take or retain the required shape by rolling, other mechanical means may
be employed, the most convenient being the thickening or strengthening of the
edges or other parts as with a selvedge or running in a cord wire or the like.
With leather this may be effected by thickening the edges or other parts in the
rolling process. Fig. 3 shows the cover with wires cords chains or the like E and
the leather also rolled or thickened at E. Fig. 4 shows the canvas cover woven
thicker at E.
The cover G in Figs. 3 and 4 may either be placed upon the ordinary cover
which contains the air-tube or it may be used in place of the ordinary cover and
fit direct over the air tube.
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. A band or cover applied to the tread or exterior of a pneumatic tyre and
retained in position by the inflation of the tyre the central diameter D-D being
greater than the side diameters C-C.
2. The combination with a pneumatic tyre of a band or cover the face next to
the tyre coinciding with the curve of the tyre for the purpose of retaining the
band upon the tyre without the use of cement or other fastening.
3. The combination with a pneumatic tyre cover of a protecting or non-slipping
leather band.
4. A combined pneumatic tyre cover and protecting or non-slipping leather
band.

page_text: 5. In a band such as described shaping the band by rolling or other mechanical
means substantially as described to enable it to retain its position upon the tyre.
