Complete Specification Left, 8th Nov., 1897-Accepted, 11th Dec., 1897
I, WALTER EAST, of Glenmore, The Avenue, Southampton in the County of
Southampton, do hereby declare the nature of this invention to be as follows:-
According to this invention the rim is made of a T-section, the arms of which may
be slightly rounded and the shank may be provided with hoops or projections to
prevent the tyre rolling off.
In the case of a tyre of the Fleuss type, the shank of the T passes between the
edges of the tyre and hooks are fixed to the flap which engage internally with the
edge of the tyre other than that to which the flap is attached.
In fixing the outer cover of a pneumatic tyre, either double hooks are provided
which engage internally with the thickened edges of the cover, or hooks are
attached on each side of the shank of the T by flexible bands, which engage in a
similar way or a single tube or solid tyre is provided with two longitudinal beads on
the outside which lit grooves or recesses formed between the shank and the arms of
the T.
I, WALTER EAST, of Glenmore, The Avenue, Southampton in the County of
Southampton, 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 :-
According to this invention the rim is made of a T section, the arms of which may
be slightly rounded and the shank may be provided with hoops or projections to
prevent the tyre rolling off.
Figure 1 is a transverse section of a rim and tyre of the Fleuss type modified in
accordance with this invention.
a is the rim and a¹ a flange or ridge projecting inwardly from it-b is the tyre and
c the flap fixed to the right hand edge of it-c¹ is one of a number of hooks fixed to
the flap and engaging with a corresponding ridge or bead on the left hand edge of the
tyre.
Figure 2 is a transverse section of a somewhat similar tubeless tyre. In this case
each edge of the tyre is formed with a ridge or bead to engage with the hooked edges
of a metallic band d extending all round inside the tyre but not having its ends
joined together. This band is not fixed to the flap c.
Figure 3 shows a somewhat similar arrangement to Figure 2 but in this case a

page_text: pneumatic tube e is employed. Figures 4 show various forms which may be used for
the band d.
In Figure 5 the band d is replaced by spring hooks f rivetted to the stem of
the T.
In Figure 6, g are plates, between the outer tyre b and the pneumatic tube e,
which are pressed down onto the tyre b by the screws h.
In Figure 7 the stem of the T is slotted as shewn in section in a plane parallel to
the axle of the wheel at Figure 8 and in radial section at Figure 9. The edges of the
tyre b carry loops ; which pass through the slots.
Figures 10 and 11 show a similar arrangement in which the loops j are replaced by
T pieces k.
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 I wish it to be
understood that I do not claim broadly the use of rims of a T shaped section but
what I claim is :-
1. The combination of a rim of T shaped section and hooks engaging with the
tyre or rim substantially as described.
2. Tyres and wheels substantially as described and shown in the drawings.
