Improvements in and relating to Tyres for Cycles and other Road
Vehicles.
I, ROBERT SCHULTZ, of 17, Melanchthonstrasse, Berlin, in the Empire of Ger-
many, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
With the object of preventing the side-slipping or falling particularly of
bicycles, pneumatic tyres or solid tyres have been frequently provided with
ribs extending around the whole circumference of the tyre. But notwithstand-
ing this arrangement, side-slipping of the bicycle has never been wholly pre-
vented, especially in curves and on wet or frozen roads.
Now the present invention has for its object to obviate this drawback by pro-
viding the wheel tyre with a covering composed of suitable material (woven
fabric, braided material or the like) which can be applied without taking the
wheel to pieces, and which is adapted to increase the adhesion between the
wheel tyre and the road or track, and thus prevent the bicycle from slipping.
The accompanying drawings illustrate two suitable forms of carrying out the
present invention. In these drawings:--
Figure 1 shows an arrangement in which a single insertion is employed, and
Figure 2 shows an arrangement in which two insertions are employed.
woven
The covering of the rubber tyre, which is so arranged that it can be used
without taking the wheel or the bicycle to pieces, may consist of a
fabric or braided material composed of cotton, wool, jute, flax hemp, or any
other desired textile fibres, or it may also be composed of horsehair, camel's
hair, hair felt, or the like. For example, a band may be wound spirally
around the entire tyre for effecting the purpose in view. For practical reasons,
however, it is preferable to construct the insertion to be employed, in the form
of a flat ring that corresponds to the periphery of the tyre. The ring, which is
made of suitable material, is either inserted in a recess provided in the tyre, or
it may be arranged between two of the above mentioned longitudinal ribs with
which the tyre is provided, as shown in Figures 1 and 2. The insertion made
in the form of a flat ring is marked a in the figures.
Furthermore the insertion may also be made by coating it on one side with
rubber, or it may be, impregnating it with rubber, whilst it is provided on the
other side with a covering composed of the above mentioned materials, said
covering being adapted to increase the adhesion.
By this means there is the possibility of being able in fine weather to use
that side of the tyre-insertion which is coated with rubber, whilst, on the con-
trary in bad weather (rain or frosty weather) that side of the annular insertion
which serves to increase the adhesion, can be employed.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
-
(1) In pneumatic tyres or solid tyres, the arrangement of a covering which
may surround the tyre partially or entirely, and which is composed of

tile fibres, horse hair, camel's hair, hair felt, or the like) and which serves to
increase the adhesion, said covering being alapted to be used without taking
the wheel or bicycle to pieces for the purpose of preventing side slipping of
the bicycle on wet or frozen roads.
(2) A form of construction of the arrangement specified in Claim 1, con-
sisting of an insertion conforming to the periphery of the wheel tyre and
having the form of a ring, and being composed of any desired textile woven
fabric or braided material or even of horse hair, camel's hair, hair felt, or the
like, said insertion being either inserted in the wheel tyre, or being arranged
between the ribs with which the rubber tyre is usually provided.
(3) A form of construction of the arrangement specified in Claim 1, con-
sisting of an insertion having the form of a flat ring, and conforming to the
diameter of the wheel tyre, one flat side of said insertion being covered, or, it
may be, impregnated with rubber, whilst its other flat side is made of textile
woven fabric or braided material, or of horse hair, camel's hair, hair felt or
the like, for the purpose of enabling the rubber side of the insertion to be used
in fine weather, and also of enabling that side of the insertion which is covered
with material adapted to increase adhesion, to be used in bad weather.
