We, FERDINAND ARTHUR SICHEL, Merchant, and JOHANN LUDWIG, Tinker, both of
Schillerplatz, Mayence, in the German Empire, do hereby declare the nature
f this invention to be as follows:-
This invention has for its object to provide a metal tyre which can be used in
substitution for pneumatic tyres for cycles or other vehicles.
The tyre made in accordance with this invention consists of a number of spring
metal strips placed transversely to the rim, such strips being bent so as to form
the tread and with the ends bent so as to fit into the rim of the wheel and to
present an open part or slot such that when the tyre is mounted in place on the
wheel the parts which engage with the rim apply themselves under pressure
against the edges of the rim and hold the tyre in position.
Interwoven with the said metal strips are other strips of a thinner metal,
arranged longitudinally, that is, parallel with the periphery of the wheel. The
ends of the first named spring strips may be prolonged and each be formed into
semi-circular, or approximately semi-circular, parts extending over the interior
of the tyre and having their ends overlapping so as to support the tyre and
counteract strain in a transverse direction.
A metal tyre thus produced answers as a substitute for a pneumatic tyre, but
we preferably provide it with a cover which may be of the usual, or any suitable,
description.
Or in place of using a cover either or both the warp and weft strips, prior to
the interweaving, may be covered with textile fabric or strips of cloth, leather,
felt, or the like. If this plan be employed we prefer to cover the whole with
india rubber solution, or similar elastic material, capable of penetrating between
the interstices.
Or we may cover the outside of the tyre with india rubber, or the like, and
while it is in a liquid or plastic state, apply thereto a strip of fabric, leather,
india rubber, or the like. In this way an elastic tyre will be obtained, not only
equal to the best pneumatic tyre, but excelling it in not being liable to be
punctured and in not requiring inflation.

3, Schillerplatz, Mayence, in the German Empire, do hereby declare the nature
of this invention and in what manner the same is to be performed to be par-
ticularly described and ascertained in and by the following statement:-
This invention has for its object to provide a metal tyre which can be used in

The tyre made in accordance with this invention consists of a number of spring
metal strips placed transversely to the rim, such strips being bent so as to form

strips may be prolonged and each be formed into semi-circular or approximately
semi-circular parts extending over the interior of the tyre and having their ends
overlapping so as to support the tyre and counteract strain in a transverse
direction.
Figure 1 represents in perspective a portion of a tyre made as aforesaid with-
out the ends being extended inside and Figure 2 represents a portion of a tyre
with the ends extending inside as aforesaid.
Figures 3 and 4 represent a single strip a of the kind last described the said
figures representing it respectively in its normal position and in the position, into
which the said strips must be brought to enable the second named strip b (con-
stituting the warp) to be interwoven with the first named (or weft) strips a.
A metal tyre thus produced answers as a substitute for a pneumatic tyre but
we preferably provide it with a cover which may be of the usual, or any suitable,
description. Or in place of using a cover, either or both the warp and weft
strips, prior to the inter-weaving, may be covered with textile fabric or strips of
cloth, leather, felt, or the like. If this plan be employed we prefer to cover the
whole with india rubber solution or similar elastic material, capable of penetrat-
ing between the interstices.
Or we may cover the outside of the tyre with india rubber or the like, and
while it is in a liquid or plastic state, apply thereto a strip of fabric, leather,
india rubber or the like. In this way an elastic tyre will be obtained, not only
equal to the best pneumatic tyre but excelling it in not being liable to be punc-
tured and in not requiring inflation.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what
claim is:-
we
1. An elastic tyre consisting of spring metal strips interwoven as described and
presenting a longitudinal slot the transverse strips being so shaped or bent as to
provide parts which engage by their springing action with the rim of the wheel
to which the tyre is applied substantially as hereinbefore described.
2. An elastic tyre consisting of spring metal strips interwoven as described and
presenting a longitudinal slot the transverse strips being so shaped or bent as
to provide parts which engage by their springing action with the rim of the

page_text: wheel and having their ends bent inwards and extending over the interior of the
tyre to support the same transversely substantially as hereinbefore described.
3. An elastic tyre consisting of spring strips interwoven and bent as described
and having applied to the transverse or the longitudinal strips or to both; such
strips, cloth, felt, rubber, leather, or other material or combinations of materials
as set forth to form a good running surface substantially as hereinbefore described.
