Improved Means for Attaching Pneumatic Tyres to the Rims of
Velocipede and other Wheels.
We GUSTAV SCHREINER of 4 Adie Road Haminersmith, Watch Maker and
GASTON HERVIEU of 73 Cambridge Road Hammersmith Engineer both in the
County of Middlesex, 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 relates more particularly to the attachment of pneumatic tyres to
the rims of velocipede wheels and has for its object a means for attaching same
whereby any portion or the whole of the air tube is easily accessible for repairing
in the event of the same being punctured.
And in order that our said invention may be fully understood we will refer to
the drawings accompanying this Specification in which
Fig. 1. shews section of tyre attached to the rim of a velocipede wheel according
to our invention and Fig. 2. shews a similar section of a modification hereafter
referred to.
Figs. 3, to 9 shew details.
Similar letters denote the same parts in all the views.
a shews the air tube b shews canvas ou which india rubber forming the outer
covering is solutioned, to this outer cover hook pieces c are attached by cutting a
slit through canvas and rubber and forcing same through as shewn at Fig. 3,
these pieces c. being held securely in the canvas by the cross arms d. The hook
piecc. are stamped out of sheet metal and formed hollow in order to strengthen
thems shewn in cross section Fig. 9. e shew slots formed round the inside of
the rim f. so that when the hook pieces c. are passed through the slots e. and the
tyre is pressed against the rim the tongues g and . on the pieces c. will take under
the slots e. and the more the tyre is inflated the tighter will the tongues y. h. be
forced against the convex portion i. of the rim and consequently the air tube a.
and outer covering b. forming the tyre will be securely held to the rim.
The above described tyre will be very suitable for racing tyres.
Fig. 2. shews tyre suitable for roadsters in which case the canvas b. (without
rubber) is passed over the air tube a. and secured to the rim (by means of the hook
pieces c. and slots e.) in the same way as described with reference to Fig. 1. and
over this we attach an outer covering of india rubber or other suitable material by
means of the hooks k. which we hook on to the spokes of the wheels. The hooks k.
have also arms d. which secure these hooks in the rubber after passing through slits
cut therein to receive them at both sides. We solution canvas on this portion of
the rubber covering so as to strengthen it where the hooks pass through and the
sides of the rubber covering are turned over and solutioned on to the surface (the
inner one by preference) as shewn in Fig. 7. by this means a row of hooks is
fixed on either ride of the covering and when this is hooked over the tyre the
spaces between the hooks will not bulge, on account of the ends of the arms d
touching one another and thus forming a ring (jointed as it were between each of
the arms) round the tyre shewn dotted at a Fig. 7. the same also applies to the
hook pieces c. When it is required to get at the air tube for repairs it is simply
necessary to deflate the tyre when the hooks k. can easily be unhooked from the
spokes as also the hook pieces e from the rim by pressing the tyre in near the rim
when the tongues g h will be released from the rim and the whole of the pieces c.
will come through the slots e. and thus expose the air tube either all round or at
any desired portion according to the number of hooks k. and pieces c. that are
unhooked.

page_text: It is obvious that instead of the hooks k taking on to the spokes they may take
on to pins provided in the rim for that purpose.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim as our invention is :-
-
1. In pneumatic tyres the hook pieces c. (provided with arms d) in combination
with slots e. all substantially as and for the purposes specified.
2. In pneumatic tyres the hooks k provided with arms d. substantially as and for
the purpose specified.
