Improvements in and connected with Pneumatic Tyres for and
Rims or Felloes of Cycles and other Vehicles
I, JOHN WALTER FLETCHER of 7 Kedleston Street, Derby in the County of
Derby, Confectioner, 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 :--
The objects of my invention are to provide an improved method of securing
pneumatic or air or gas inflated tyres to the rims or felloes of wheels of cycles oi
other vehicles. to effect certain improvements in and connected with the said rim
or felloes for the same purpose aud also to minimise the danger of the said
pneumatic tyre or inner tube becoming punctured, cut or otherwise daninged by
coining into contact with the said rim or telloe.
Refering to the drawings which form a part of this Specification:-
Figure 1 is a transverse section through a pneumatic tyre and rim manufactured
according to my invention
Figure 2 is a transverse section through the outer jacket only of my improved
tyre when removed from the m
Figure 3 is a transverse section shewing a solid run manufactured according to
my invention
Figure is a section shewing the junction of the two ends of a steel or other
band to be hereinafter descubed.
I will first describe that part of my invention relating to the securing of the
tvre to the rim or felloe; it will be seen upon referring to the drawings that my
invention relates more particularly to that class of pneumatic tyre consisting of
an inner tube A which is inflated and provided with a non-return valve in any now
well known maunei, an outer jacket B having a thickened-out bearing surface C
to also assist in minimising the danger of puncture, the two latter parts B and C
being of any suitable material or materials and fastened together in any suitable
manner and having annular wies D for fixing the said tyres to the rim or felloe.
As hitherto made the annular wires D have been placed at and have formed the
extreme edges of the outer jacket thus necessitating their being placed in a deep
rim to keep them fixed therein, now by my invention I cause the said wires D to
be fixed so that a small portion E of the outer jacket on cach side thereof passes
beyond the wire so that when fixed on a rim with a shallow bed such as F and G
the portions E will roll under the wnes D and hold the tyre much more securely
in position than without the aid of the said portions E.
It will be seen upon referring to Figures 1 and 3 that I form my improved rims
either hollow or solid with a flat bed For G and two voiy slightly inclined sides II
the object of which is to keep the bearing surface of the tyre upon the um as flat
as possible and so obtain the greatest amount of resilience therefrom, prevent side
slipping, and enable me to have this tyre fixed to existing old shallow rims without
rebuilding the wheel and putting on new rims.
I effect a further improvement in the case of hollow or other 11ms by providing
a band I see Figures and 4 of steel or of any other stable hard material such
38 xylonite, aluminium or the like, this is passed round the flat bed F of the rin
to cover up any holes or sharp edges in the latter consequent upon fixing the
pokes H and also provides a level and even bed for the reception of the tyie.
In fixing this band a small boss K may be provided on one end I thereof while
ID 23

has an orifice formed therein which fits over the said boss K and
be secured with a screw I, the said boss fitting in one of the holes
the whole is evident however that the two ends of the band may be secured
in the rim.
in a variety of ways, for instance they may have holes formed therein and be
overlapped until the two holes come concentric with each other and the neck of
the non-return valve affixed to the inner tube be passed through the said hole
It will also be evident that a band of steel or other suitable hard material may
be used for the above purpose in connection with other forms of rims and
pneumatic tyres than those hereinbefore described and illustrated.
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 18
-
1. The projecting edges E of the outer cover or jacket of the tyre substantially
as and for the purposes described and illustrated.
2 The projecting edges E of the outer cover or jackot of the tyre in combination
with a rim o felloe having a shallow bed or bearing surface for tho said tyie
substantially as and for the purposes described and illustrated.
3. The band of steel, xylonite, aluminium or other suitable hard material in
combination with hollow or other rims and pueumatic tyres substantially as and
for the purposes described and illustrated.
4. The whole substantially as and for the purposes described and illustrated.
