PROVISIONAL SPECIFICATION.
Improvements in Caoutchouc Tyres or Rim-coverings for Carriages
and other Vehicles.
I, CARL SCHWANITZ of No. 179B Müllerstrasse Berlin, Germany, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved construction of caoutchouc wheel tyres or
rim-coverings in which, for the purpose of increasing the elasticity between the
felloe or rim and the caoutchouc tyre, a suitably formed insertion of a softer caout-
chouc, or of caoutchouc sponge is employed.
The accompanying drawing shews several arrangements for carrying out my said
invention.
In Figs. 1 to 3. C is the felloe or rim of the wheel, A is the solid caoutchouc
tyre and E is the insertion of softer caoutchouc.
Instead of introducing the softer caoutchouc between the solid caoutchouc tyre
and the felloe, it can be introduced in one or more layers into the caoutchouc tyre A
itself, so that the rim covering consists of alternate layers of harder and softer
caoutchouc, as at Fig. 4.
On using a vehicle provided with tyres or rim coverings such as described with
reference to Figs. 1 to 4, the pressure of the load will be transmitted through the
caoutchouc tyre A to the caoutchouc insertion E, which, in consequence of its
greater softness will produce an increased elastic action of the caoutchouc tyre, and
will consequently insure a uniform ease and safety of motion, and a preservation of
the vehicle.
In place of the insertion of softer caoutchouc may also be used an insertion of
spongy caoutchouc, such as shewn at Figs. 5 to 8, the form of which can be modified
at will, corresponding to that of the felloe or rim, and the pores of which are partly
filled with gas and partly with air, so that it will have the same elastic action as the
insertion of soft caoutchouc according to Figs. 1 to 4.

I, CARL SCHWANITZ of No. 179B Mullerstrasse, Berlin, Germany, Manufacturer,
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 :-
My invention relates to an improved construction of caoutchouc wheel tyres or
rim-coverings in which, for the purpose of increasing the elasticity between the
felloe or rim and the caoutchouc tyre, a suitably formed insertion of a softer caout-
chouc, or of caoutchouc sponge is employed.

page_text: The drawing accompanying my Provisional Specification shews several arrange-
ments for carrying out my said invention.
In Figs. 1 to 3, C is the felloe or rim of the wheel, A is the solid caoutchouc
tyre and E is the insertion of softer caoutchouc.
Instead of introducing the softer caoutchouc between the solid caoutchouc tyre
and the felloe, it can be introduced in one or more layers into the caoutchouc tyre A
itself, so that the rim-covering consists of alternate layers of harder and softer
caoutchouc, as at Fig. 4.
On using a vehicle provided with tyres or rim-coverings such as described with
reference to Figs. I to 4, the pressure of the load will be transmitted through the
caoutchouc tyre A to the caoutchouc insertion E, which, in consequence of its
greater softness will produce an increased elastic action of the caoutchouc tyre,
and will consequently insure a uniform ease and safety of motion, and a preser-
vation of the vehicle.
In place of the insertion of softer caoutchouc may also be used an insertion of
spongy caoutchouc such as shewn at Figs. 5 to 8, the form of which can be
modified at will, corresponding to that of the felloe or rim, and the pores of
which are partly filled with gas and partly with air, so that it will have the same
elastic action as the insertion of soft caoutchouc according to Figs. 1 to 4.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :
1. Caoutchouc tyres or rim-coverings in which there is provided between the
solid caoutchouc tyre A and the rim C a suitable caoutchouc insertion E of a softer
quality than the tyre, in order to render the tyre more elastic and thus render the
travelling more agreeable substantially as described.
2. A construction of the caoutchouc tyre referred to in the first claim in which
the insertion of a softer caoutchouc E is introduced into the caoutchouc tyre
substantially as described.
3. A construction of the tyre referred to in the first claim, in which the insertion
between the tyre and the rim is made of spongy caoutchouc substantially as
described.
