Improvements in or relating to Elastic Tyres for the Wheels of Cycles
and other Vehicles.
I, FRANCIS BEAUCHAMP, of Sunny Side, The Green, South Tottenham, in the
County of Middlesex, Engineer, do hereby declare the nature of this invention
to be as follows:
This invention relates to improvements in wheels of vehicles generally, but
which are more especially applicable to the wheels of cycles and other similar
carriages.
In
According to this invention I employ a rim of any convenient section, and in
the hollow of such rim, and projecting radially from the centre of the wheel,
I provide any convenient number of indiarubber, or other more or less resilient
blocks, of cylindrical or other convenient shape. On the outer surfaces of these
resilient blocks, and circumferentially of the wheel, I provide a hollow ring of
thin steel or other suitable metal or material preferably of a D section, the
straight side of the D resting on the resilient blocks, which latter may be attached
to the said ring and to the rim by cement or by other convenient means.
some cases I employ a hollow ring of circular section; and in order to increase
the resiliency of the hollow ring I sometimes form notches or saw-cuts on the
inner periphery thereof of any convenient or suitable form. The ends of the
hollow ring may be butt-jointed and fixed together by any convenient means,
or a certain amount of motion may be allowed for between the adjacent ends,
which latter may be arranged to slide in a sleeve or socket for this purpose.
The hollow ring is preferably clothed in a soft fabric or other material such for
example as flannelette, and the whole is held in place by a cover or tread of
indiarubber or other suitable material, the edges of which are beaded and are
held tightly in the rim and over the hollow ring by means of wires with screwed
pins, which latter are passed through the edges of the rim and fastened by nuts
or otherwise. The cover or tread is thus stretched tightly over the hollow ring
and the whole forms an unpuncturable resilient tyre.

Improvements in or relating to Elastic Tyres for the Wheels of Cycles
and other Vehicles.
I, FRANCIS BEAUCHAMP, of Sunny Side, The Green, South Tottenham, in the
County of Middlesex, Engineer, 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 to improvements in wheels of vehicles generally, but such
Price 8d1

page_text: improvements are more especially applicable to the wheels of cycles and other
similar carriages.
According to this invention I employ a rim of any convenient section, and in
the hollow of such rim, and projecting radially from the centre of the wheel, I
provide any convenient number of indiarubber, or other more or less resilient
blocks, of cylindrical or other convenient shape. On the outer surfaces of these
resilient blocks, and circumferentially of the wheel, I provide a hollow ring of
thin steel or other suitable metal or material preferably of a D section, the
straight side of the D resting on the resilient blocks, which latter may be
attached to the said ring and to the rim by cement or by other convenient
means.
In the accompanying drawings Figure 1 is a transverse section of the tyre
portion of a cycle wheel constructed in accordance with my invention, Figure 2
is a longitudinal section and Figure 3 an elevation of the same, Figures 4 and 5
illustrate in transverse section and elevation respectively a modification of my
invention.
Similar letters relate to like parts in all the figures of the drawings. Referring
to Figures 1, 2 and 3, a is the rim of the wheel b the spokes. In the hollow of
the rim a are arranged in any required number and of any convenient shape the
india rubber or other resilient blocks c. d is a hollow ring of steel or other
suitable metal or material, shewn of ☐ section with notches or saw-cuts e on the
inner periphery in order to increase its resiliency. These notches or saw-cuts
may be of any desired number and shape and may extend more or less into the
material of the ring d. The ring d is preferably enveloped or clothed in a soft
fabric or other material f such for example as flannelette. g is a cover or tread of
indiarubber or other suitable material the edges of which are beaded as shewn and
contain any convenient number of lengths of wire h the ends of which are screw-
threaded, bent at right angles and passed through the said bead and through holes
in the rim a as shewn and to which they and consequently the cover or tread g are
securely held by nuts i or by other suitable means.
In Figure 4 the ring d is shewn of a circular section and the notches or saw-
cuts e are cut nearly half way through the said ring in order to increase its
resiliency. The ends of the ring d, of whatever section it may be, may be
butt-jointed and fixed together by any convenient means, or a certain amount
of motion may be allowed for between the adjacent ends, which latter may be
arranged to slide in a sleeve or socket for this purpose. Or the ends may be
plugged and halved together being held secure by a screw passing through the
two halved portions of the adjacent ends.
When the metal ring d with its covering f is in place resting on the resilient
blocks c, and the cover or tread g is stretched tightly over the whole by the nuts i
a highly resilient but unpuncturable and non-collapsible tyre is obtained.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
First. An elastic tyre for the wheels of cycles and other vehicles which consists
of a hollow resilient ring d, with or without notches or saw-cuts e, resilient
blocks e and a cover or tread g secured in place on the rim a by wires h sub-
stantially as described with reference to the drawings.
Second. The clastic tyre for the wheels of cycles and other vehicles con-
structed, arranged and operating substantially as described.
