PROVISIONAL SPECIFICATION.
Improvements in Tyres for Velocipede and other Wheels.
I, HENRI TANGHE, of 13 Rue des Augustins, Brussels, in the Kingdom of
Belgium, Mechanician, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is the production of a new tyre for velocipede and
other wheels, advantageously replacing the so called pneumatic tyre. For this
purpose the felly of the wheel is made of crescent section having the edges bent
inwards so as to present non-cutting surfaces. This felly thus made is surrounded
with a band of caoutchouc or other elastic material which forms the chord of an
arc across the section of the felly; at the place where it forms the chord this band
is strongest. I cover this band by a second band of caoutchouc which is the tyre
properly so called. This latter band which may be of another elastic material has
a section having an internal projection or flange thereon which touches the middle
of the inner band at the axis of the chord of the arc in such manner that by the
pressure produced on the wheel this internal projection is pushed against the band
whereby a spring movement is given, similar to that of the so called pneumatic
tyre. The ends of the bands receive or embrace the back of the felly up to the
proximity of the line of the spokes of the wheel. These bands are then covered
or partially covered with a fabric band, or other material, strongly cemented in
such manner that the whole is very firmly held together.
Dated this 5th day of May 1892.

COMPLETE SPECIFICATION.
Improvements in Tyres for Velocipede and other Wheels.
I, HENRI TANGHE, of 13 Rue des Augustins, Brussels, in the Kingdom of
Belgium, Mechanician, 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 :—
The object of my invention is the production of a new tyre for velocipede and
other wheels advantageously replacing the so-called pneumatic tyre. For this
purpose, and as shewn in vertical cross section by the accompanying drawing, the
felly of the wheel is made of crescent or similar section, having the edges a a bent
upwards so as to present non-cutting surfaces. The felly thus made is surrounded
with a band of caoutchouc or other elastic material A, which forms the chord of
an arc across the section of the felly. At the place where it forms the chord this
band A is strongest. 1 cover this band by a second band of caoutchouc B, which
is the tyre properly so called. This latter band B is formed with an internal
projection or flange thereon C, which touches or bears upon the middle of the inner
band A at the axis or middle point of the chord of the arc; in some cases a tube
may be substituted for the solid flange C. By the pressure of the wheel upon the
road this internal projection C is pushed against the band or chord of the arc A,
whereby a spring movement or elasticity is given, similar to that of the so-called
pneumatic tyre. The ends of the bands A and B receive or embrace the back of
the felly up to the proximity of the line of the spokes of the wheel. These bands
are then covered or partially covered with a band of fabric or other material D,
strongly cemented in such manner that the whole is very firmly held together.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Tyres for relocipede and other wheels, composed of a metal crescent-section
felly, formed with non-cutting edges, a band of elastic material, externally
embracing and bridging the arc of the said felly, an outer cover externally
embracing the aforesaid band and felly, and having an internal projecting flange
or tube to rest and act upon that part of the band which forms the chord across
the arc of the crescent felly, whereby a resilient action is produced substantially
as and for the purposes described with reference to the accompanying drawings.
Dated this 28th day of September 1892.
