Improvements relating to Pneumatic Tyres for Cycle and other
Vehicle Wheels."
I, CHARLES ANDREW EDWARD TALBOT PALMER, of The St. George's Engineering
Company Limited, l'ope Street in the City of Birmingham. Manufacturers. 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 provide simple and effective means
for preventing deflection or displacement of the inner tongue or overlapping edge
of a tubeless tyre by the projection of the spoke heads in a solid rim, the spoke
holes in the bed of a hollow rim, or from other causes tending to produce deflation
of the tyre.
In the application of my invention I form with or attach to one of the feet or
thickened edges of the tyre and on the outer side of the same, a continuous strip
of canvas, rubber, or other material -having a free over-lapping portion of such
a width that when the two edges of the cover are brought together, the outer
tongue or overlapping portion will project entirely over the foot or edge to which
it is unattached. I preferably solution or secure a thin layer of pure rubber on
the inner side of the outer tongue or overlapping strip, and on the inflation of the
tyre in the ordinary manner an air tight joint will be formed between such strip
and the foot or thickened edge forced upon it by the inner air pressure.
By the employment of my continuous outer tongue or overlapping strip I form
a bed for the feet or thickened edges of the tubeless tyre preventing any abrupt
detrusion or internal deflection or displacement of the tyre edges such as may
occur on the direct contact of such edges with the spoke heads in the case of a solid
tyre. My inner tongue or overlapping strip also prevents any portion of the feet
or thickened edges of the tyre or of the inner tongue from being blown into the
spoke holes in the bed of a hollow rim.

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 provide simple and effective means
for preventing deflection or displacement of the inner tongue or overlapping edge
of a tubeless tyre by the projection of the spoke heads in the solid rim, the spoke
holes in the bed of the hollow rim, or from other causes tending to produce deflation
of the tyre.
In the application of my invention I form with or attach to one of the feet or
thickened edges of the tyre and on the outerside of the same, a continuous strip
of canvas, rubber, or other material, having a free overlapping portion of such a
width that when the two edges of the cover are brought together, the outer tongue
or overlapping portion will project entirely over the foot or edge to which it is
unattached. I preferably solution or secure a thin layer of pure rubber on the
inner side of the outer tongue or overlapping strip, and on the inflation of the tyre
in the ordinary manner an air tight joint will be formed between such strip and
the foot or thickened edge forced upon it by the inner air pressure.
By the employment of my continuous outer tongue or overlapping strip I form.
a bed for the feet or thickened edges of the tubeless tyre preventing any abrupt
detrusion or internal deflection or displacement of the tyre edges, such as may
occur on the direct contact of such edges with the spoke heads in the case of a solid
tyre. My outer tongue or overlapping strip also prevents any portion of the feet
.or thickened edges of the tyre or of the inner tongue from being blown into the
spoke holes in the bed of a hollow rim.
In the accompanying sheet of explanatory drawings.-
Figure 1 is a transverse section of my improved tubeless tyre in its flattened
form, whilst Figure 2 illustrates the same tyre in its position upon a wheel rim,
the rim being indicated by dotted lines.
A is the outer tongue or overlapping strip hereinbefore described, attached to
one of the feet or thickened edges as B of the tyre. When the tyre is in position
on the wheel rim, the strip A overlaps the opposite edge C of the tyre to which it
is unattached and so forms a protecting bed or pad as illustrated at Figure 2.
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 use of a continuous tongue or overlapping strip on the exterior of a
tubeless pneumatic tyre substantially as and for the purposes described.
2. A pneumatic tyre for cycle and other vehicle wheels constructed and arranged
substantially as described and as illustrated.
