PROVISIONAL SPECIFICATION.
Improvements in and connected with Tyres for Velocipede and
other Road Wheels.
We, NICHOLAS YAGN, and SERGIUS BESSONOFF, both of 25 Bassemaya Street,
St. Petersburg, Russia, Engineers, do hereby declare the nature of this invention
to be as follows:-
:-
Our invention relates to improved constructions of elastic tyres for velocipede
and other road wheels, having for their object to render the motion easy and to
allow the peripheral surface of the tyre to adapt itself readily to any configuration.
of road surface, and also to reduce the wear and tear.
The caoutchouc tyres usually employed, whether solid or tubular, such as the
pneumatic tyres, suffer from the disadvantage that all parts thereof. form a united
whole, so that when in running the tyre is more or less compressed at the part
where it is in contact with the road, the several parts in contact having different
velocities in consequence of their different distances from the axis of the wheel,
some of these parts must inevitably slip on the ground and consequently will cause
increased friction which impedes the running.
The pneumatic tyres are in addition easily cut and rendered useless by sharp
stones and other objects on the road.
According to our invention we obviate these disadvantages by connecting a thin
flexible band-like tyre, of a strong resisting material, with the rim of the wheel by
means of elastic ribs or connecting pieces or springs which allow of the perfectly
free motion of the said tyre in a longitudinal or peripheral direction and con-
sequently entirely prevent the slipping thereof, so that it is only subject to rolling
friction.
On the accompanying drawing are shewn by way of example various arrangements
for carrying out our said invention.
Figs. 1, 2 and 3 shew respectively a vertical section, a horizontal section on
line 1-2, and a cross section of a caoutchouc tyre consisting of an outer band a
and an inner band b which is secured to the rim c of the wheel, and which is
connected to the outer band a by means of radial transverse ribs or buffers d d.
In the construction shewn at Figs. 4, 5 and 6 there are two rows of transverse
ribs or buffers, that is to say, they are connected together at the middle by an
intermediate band e; in addition, the ribs or buffers are in this case arranged
obliquely in the transverse direction, as shewn at Fig. 5.
Figs. 7, 8 and 9 shew a similar construction of tyre to Figs. 1, 2 and 3, in which
the side surfaces are enclosed in order to prevent the entrance of dust and dirt in
the spaces between the ribs.
Figs. 10, 11 and 12 shew a tyre with longitudinal ribs d¹ d' which are connected
together by the outer and inner bands a and b, and by an intermediate band e,
which latter can be dispensed with.
Figs. 13, 14 and 15 shew a caoutchouc tyre which has transverse passages formed
through it, which may be either of regular or irregular form, such as in spongy
caoutchouc, which may consequently also be used.
Lastly, Figs. 16, 17 and 18 shew a method of connecting the outer band a with
the rim c of the wheel by means of metallic springs g.
In order to render the outer band a strong against compression and tension,
there are introduced into the body thereof wires, cords or strips of woven fabric.
The fixing of the said tyres upon the rim of the wheel can be effected in various
ways; at Figs. 1, 3, 4, 6, 7, 9, 13 and 15 is shewn by way of example a method of
fixing by binding the inner band to the wheel rim by means of cord or twine.

page_text: The inclined position of the ribs d as at Fig. 5 allows of such binding being correctly
wound round the parts.
It will readily be understood that a variety of other forms might be adopted for
carrying out our said invention.

COMPLETE SPECIFICATION.
Improvements in and connected with Tyres for Velocipede and
other Road Wheels.
We, NICHOLAS YAGN, and SERGIUS BESSONOFF, both of 25 Bassemaya Street,
St. Petersburg, Russia, Engineers, 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 :-
Our invention relates to improved constructions of elastic tyres for velocipede
and other road wheels, having for their object to render the motion easy and to
allow the peripheral surface of the tyre to adapt itself readily to any configuration
of road surface, and also to reduce the wear and tear.
The caoutchouc tyres usually employed whether solid or tubular, such as the
pneumatic tyres, suffer from the disadvantage that all parts thereof form a united
whole, so that when in running the tyre is more or less compressed at the part
where it is in contact with the road, the several parts in contact having different
velocities in consequence of their different distances from the axis of the wheel,
some of these parts must inevitably slip on the ground and consequently will cause
increased friction which impedes the running.
The pneumatic tyres are in addition easily cut and rendered useless by sharp
stones and other objects on the road.
According to our invention we obviate these disadvantages by connecting a thin
flexible band-like tyre, of a strong resisting material, with the rim of the wheel by
means of elastic ribs or connecting pieces or springs which allow of the perfectly
free motion of the said tyre in a longitudinal or peripheral direction and con-
sequently entirely prevent the slipping thereof, so that it is only subject to rolling
friction.
On the drawing accompanying our Provisional Specification are shewn by way
of example various arrangements for carrying out our said invention.
Figs. 1, 2 and 3 shew respectively a vertical section, a horizontal section on
line 1-2, and a cross section of a caoutchouc tyre consisting of an outer band a
and an inner band b which is secured to the rim c of the wheel, and which is
connected to the outer band a by means of radial transverse ribs or buffers d d.
In the construction shewn at Figs. 4, 5 and 6 there are two rows of transverse
ribs or buffers, that is to say, they are connected together at the middle by an
intermediate band e; in addition, the ribs or buffers are in this case arranged
obliquely in the transverse direction, as shewn at Fig. 5.
Figs. 7, 8 and 9 shew a similar construction of tyre to Figs. 1, 2 and 3, in which
the side surfaces are enclosed in order to prevent the entrance of dust and dirt in
the spaces between the ribs.
Figs. 10, 11 and 12 shew a tyre with longitudinal ribs d' d' which are connected
together by the outer and inner bands a and b, and by an intermediate band e,
which latter can be dispensed with.
Figs. 13, 14 and 15 shew a caoutchouc tyre which has transverse passages formed
through it, which may be either of regular or irregular form, such as in spongy
caoutchouc, which may consequently also be used.
Lastly, Figs. 16, 17 and 18 shew a method of connecting the outer band a with
the rim c of the wheel by means of metallic springs g.

page_text: In order to render the outer band a strong against compression and tension, there
are introduced into the body thereof wires, cords or strips of woven fabric.
The fixing of the said tyres upon the rim of the wheel can be effected in various
ways; at Figs. 1, 3, 4, 6, 7, 9, 13 and 15 is shewn by way of example a method of
fixing by binding the inner band to the wheel rim by means of cord or twine.
The inclined position of the ribs d as at Fig. 5 allows of such binding being correctly
wound round the parts.
It will readily be understood that a variety of other forms might be adopted for
carrying out our said invention.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Tyres for velocipede and other road wheels wherein a flexible but strong hoop a
is connected to the rigid rime of the wheel by an elastic connection consisting of
elastic blocks or buffers, or transverse or longitudinal ribs or tubular or spongy
caoutchouc, or metal springs substantially as described.
