Improvements in Tyres for Velocinedes and other Vehicles
Year: 1898

Complete Specification Left, 17th Oct., 1333-Accepted, 10th Dec., 1898
We, FERDINAND SICHEL, and JOHANN LUDWIG, both of Mainz, in the Empire of
Germany, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved tyre for velocipedes or other vehicles
which is of as resilient a character as a pneumatic tyre and which is not rendered
unfit for use by puncturing.
According to this invention we use a metallic fabric or gauze, the weft of which
consists of blade springs whilst the warp is formed of small sheet metal strips or
wires.
In this manner a fabric, elastic in transverse direction is obtained, which, when
fitted with its edges into the rim of the wheel, serves as a perfect substitute for a
pneumatic tyre.
In order that this metallic tissue or gauze may be readily retained in the rim
without further auxiliary means, its weft springs have both their ends bent into
hook form so as to embrace the groove of the rim and to rest upon the outer sur-
face of the said groove. The weft springs thus fixed are, without the use of any
other auxiliary means, prevented from becoming vertically displaced.
Or instead of the ends of the weft blades being hook shaped they may be bent
at right angles so as to solely rest upon the top of the outer surface of the
grooves and to laterally bear against the side of the grooves whilst
the inner space of the groove is filled up by the thickened edges of the
outer rubber covering of the metal gauze or fabric so that the said cover is re-
tained in the rim without any auxiliary fastening.
This improved tyre is applicable to any kind of rim provided with lateral
grooves.
Instead of using leaf springs, springs of other shape may be employed.

Improvements in Tyres for Velocinedes and other Vehicles
We, FERDINAND SICHEL, Merchant, and JOHANN LUDWIG, Tinker, both of
Mainz, in the Empire of Germany, 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:-

We, FERDINAND SICHEL, Merchant, and JOHANN LUDWIG, Tinker, both of
Mainz, in the Empire of Germany, 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 an improved tyre for velocipedes or other vehicles,
which is of as resilient a character as a pneumatic tyre and which is not rendered
unfit for use by puncturino.

page_text: According to this invention we use a metallic fabric or gauze, the weft of which
consists of blade springs, whilst the warp is formed of small sheet metal strips, as
shewn in transverse section and plan in Figure 1 or of wires as shewn in similar
views in Figure 2, of the accompanying drawing, in which a represents the weft-
springs and 6 the sheet metal strips, or wires, forming the warp of the fabric or
gauze.
In this manner a fabric is obtained which is elastic transversely and which, when
fitted by its edges into the rim of the wheel, serves as a perfect substitute for a
pneumatic tyre.
In order that this metallic tissue, or gauze, may be readily retained in the rim
without further auxiliary means, its weft springs a have both their ends bent
into hook form as represented, so as to engage the groove of the rim as illustrated
in the transverse section of the tyre applied to a rim in Figure 1 and also to
bear upon the outer surface of the said groove. The weft-springs thus fixed are,
without the use of any other auxiliary means, prevented from becoming vertically
displaced.
The arrangement may also be as represented in Figures 3 and 34.
In this case the ends of the weft springs a are not hook shaped but merely
bent, as shewn, so as to rest upon the top of the outer surface of the grooves and
only bear laterally against the sides of the grooves, whilst the inner spaces of the
grooves are filled by the thickened edges d of the outer covering of the metal
gauze or fabric, which covering may consist of india rubber or other suitable
material. In this manner the cover is likewise secured to the rim without any
further or auxiliary means.
This improved tyre is applicable to any kind of rim provided with lateral grooves.
Instead of using leaf springs, springs of other shape may be employed.
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 we claim
is:-
1. A tyre for wheels, the said tyre consisting of or comprising a metallic fabric
or gauze, the warp of which consists of narrow metal strips or of wires, and the
weft of which consists of flat metal springs the ends of which can be fitted into,
or engaged with, the grooves of the rim, substantially as hereinbefore described.
2. A tyre for wheels, the said tyre consisting of a metallic fabric or gauze, the
warp consisting of metal strips or of wires and the weft of flat metal springs having
ends of such form as to hook into the grooves in the rim, and also to rest upon
the outer surface of the rim, substantially as herein before described.
3. A tyre for wheels, the said tyre consisting of a metallic fabric or gauze, the
warp consisting of metal strips or of wires and the weft of flat metal springs, and
a cover of India rubber or like material formed with edges to engage with the
grooves in the rim the ends of the weft springs being bent so as to press the cover
against the edges of the rim, substantially as herein before described.
Dated this 17th day of October 1898.
