Improvements in Pneumatic Tyres.
I, CHARLES STOTESBURY, of 45 East Dulwich Grove, in the County of Surrey,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to pneumatic tyres of the single or double tube variety, and
may be carried into effect in the following manner:-
Any suitable rim may be employed, preferably with a deep channel, the tyre
itself being formed of substantially the usual materials, say rubber and canvas
and each edge provided with a hook and extension or flap. The edges are hooked
into one another inside the channel of the rim, one of the flaps filling up the space
from the outer book inside the rim up to the edge or thereabouts, and the other
one filling up the space between the inside hook and the inside of the tyre so as to
make the interior of it substantially circular.
The hooks are preferably made of hard rubber lined with soft rubber while the
other parts may be made of soft rubber.
A separate air tube may be employed with this tyre if preferred, but it may be
worked as a single-tube tyre without a separate air tube. In the latter case the
canvas or fabric will be embedded in the rubber so that a continuous rubber facing
will be presented to the interior for repair purposes in the case of puncture.
The air-valve may be placed through the rim and into the tyre, to the inner
flap or edge of which it may be secured.
In a modified form the tyre may be constructed as before described but the edges
in this case may butt against each other, or need not even entirely touch, and an
internal band, preferably of hard and soft rubber, extends around the inside and
is pressed down on to the tyre by means of screwed studs or equivalent and nuts
upon the interior outer face of the rim. Annular projections upon the tyre may
engage with annular grooves in the rim. This tyre is adapted for heavy vehicles
as well as cycles.

page_text: to be performed to be particularly described and ascertained in and by the
following statement:-
This invention relates to pneumatic tyres and is as follows:-
The edges of the tyre may butt against each other or need not even entirely
touch and an internal band (advantageously of hard and soft rubber) either a con-
tinuous ring or otherwise extends around the inside of the tyre and is pressed down
on to same by means of screwed studs or equivalent passing through the rim or
felloe and having nuts or equivalent on the inside ends thereof.
Annular ridges or projections upon the tyre may engage with annular grooves
or channels in the rim. This tyre being especially adapted for heavy vehicles.
And in order that my present invention may be easily and fully understood I
will proceed to further describe same with reference to the drawing hereunto
annexed.
Fig. 1 shows a tyre O having the edges butting or meeting-but not inter-
locking at C an endless band (advantageously of hard rubber F and soft
rubber F) being placed over said abutting or adjacent edges C and headed
screws G are passed at intervals all round through same and through the felloe D
(or metal rim if used) and secured by nuts such as the pinching screw or winged
nut H.
C are the corrugations or circumferential ridges on the inner face of the tyre
and adapted to fit in the corresponding circumferential gutters or grooves D
formed to receive same in the rim D.
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:-
Pneumatic tyres constructed and arranged to act substantially in the manner
hereinbefore described and illustrated in the drawing hereunto annexed.
