Improvements in or relating to Friction Dises or Wheels.
I, FRITZ SCHEIBLER, Machine-Manufacturer, of Am Viaduct, No. 3, Aachen,
Prussia, do hereby declare the nature of this invention to be as follows:-
The present invention relates to a new means of cheaply and rapidly arrang-
ing and fixing the surface covering of friction discs.
For this purpose the covering which serves, as is generally known, to increase
the adhesion between the friction disc and the driven part, is wound round in
the form of a band, the two ends of the band being passed through a slot in
the periphery of the wheel for the purpose of being tightened and fixed under-
neath the rim.
Above the place provided for the passage of the ends of the band, will, of
course, appear a gap, recess or interruption in the covering which would have
the effect of producing shocks or vibration. In order to avoid this, the cover-
ing of the wheel is formed of several parallel bands or strips arranged side by
side the ends or joins of which are so arranged upon the periphery of the
wheel, that the gaps or joins shall not be in line laterally across the wheel,
but that the several bands shall break joint" in their arrangement.
"
One end of each band is passed through its particular slot in the wheel and
secured to the inner periphery of the wheel, the band is then wound round the
wheel and the other end is also passed through the slot, where it is secured by a
clamp and screws after having first been properly tightened.
Provision may be made for the purpose of so placing the band in position so
that it is possible afterwards to tighten it whenever required. Of course, the
fixing of the ends of the band to the inner periphery of the wheel may be effected
in any other way, without however interfering with the principle of the invention.
The periphery of the wheel is preferably provided with a ledge preventing a
lateral displacement of the bands during work. Should the wheel be used as a
change gear the ledge must be provided for also on the other side of the rim,
which, otherwise, is not necessary inasmuch as it is known that a displacement
will only take place in the direction of the periphery of the driving friction disc.

page_text: the following statement:—
The present invention relates to a new means of cheaply and rapidly arrang-
ing and fixing the surface covering of friction discs.
For this purpose the covering which serves, as is generally known, to increase
the adhesion between the friction disc and the driven part, is wound round in
the form of a band, the two ends of the band being passed through a slot in
the periphery of the wheel for the purpose of being tightened and fixed under-
neath the rim.
Above the place provided for the passage of the ends of the band will, of
course, appear a gap, recess or interruption in the covering which would have
the effect of producing shocks or vibrations. In order to avoid this, the cover-
ing of the wheel is formed of several parallel bands or strips arranged side by
side the ends or joins of which are so arranged upon the periphery of the
wheel, that the gaps or joins shall not be in line laterally across the wheel,
but that the several bands shall "break joint" in their arrangement.
In the accompanying drawings,
Figure 1 represents an elevation,
Figure 2 a plan,
Figure 3 a horizontal section, and
Figures 4 and 5 details of a friction disc or wheel according to this invention.
In Figure 4 the end of the band is represented, which, by means of the annular
part represented in Figure 5, is secured to the inner periphery of the wheel a
(Figure 1). The free end of the band is then passed through a slot provided
for it in the rim of the wheel, and the band is then wound round the wheel and
the other end is also passed through the slot, where it is secured by a clamp and
screws (Figure 5) after having first been properly tightened.
Provision may be made for the purpose of so placing the band in position
that it is possible afterwards to tighten it whenever required. Of course, the
fixing of the ends of the band to the inner periphery of the wheel may be effected
in any other way, without however, interfering with the principle of the
invention.
As can be seen from Figure 3 the periphery of the wheel is preferably pro-
vided with a ledge preventing a lateral displacement of the bands during work.
Should the wheel be used as a change gear the ledge must be provided for also
on the other side of the rim, which, otherwise, is not necessary inasmuch as it
is known that a displacement will only take place in the direction of the peri-
phery of the driving friction disc.
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. A friction wheel covering consisting of several bands or strips arranged
side by side on a wheel rim, the ends of the bands being passed through slots
in the periphery of the wheel and secured, the slots being arranged.in different
positions round the periphery of the wheel, substantially as described.
2. The complete peripheral construction of wheel substantially as described or
illustrated in the accompanying drawings.
