· Improvements in and connected with Pneumatic Tyres
for Cycles.
I, GUSTAV HILLER of 18 Lessingstrasse, Zittau, Kingdom of Saxony,
Germany, Gentleman, do hereby declare the nature of this invention to be as
follows:-
The present invention relates to a fastening device for wheel-tires consisting only
of one cover, distinguished by its simpleness and reliability and because in case of
damage the cover can be easily and well repaired.
The tire is peculiar for consisting only of one cover and being cut open all along,
towards the rim of the wheel. The edges thus obtained are provided with flanges
going all round. With these flanges the tire is placed into a rim of which the section
gets narrower at one point. The flanges are tlien by some means or other expanded
so as to closely fit to the inner wall of the rim. The tire being thus tightly held
by curvings is prevented from slipping out. In the present case a rubber tube
attached to the flange and provided with a valve is employed for expanding the
flanges.
By means of a valve the tube is inflated until the flanges are pressed against
the inner wall of the rim. Thus the tube at the same time forms a perfect
tightening, so that by inflating the tire by means of the valve, no air can escape.
Through the cover being cut open all along, the tire can be easily and durably
repaired.
Formerly, when the tire was damaged, it could be repaired only by a plaster
being put on from outside. The present tire however is for this purpose simply
opened and the plaster is applied inside the tire. Thus the plaster is not only
protected against damage but is also pressed by the interior air-pressure against the
damaged place.
Instead of expanding the flanges from inside against the rim, a tightening may
also be obtained by pressing them together from outside, for instance by means of
the insertion of strong rubber rings between the rim and the flanges, or by
mechanically pressing the rim.
The
In the outer tube and over the flanges may also be arranged an annular flexible
valve flap, extending around the tire and secured to one side of the same.
pressure of the air in the outer tube presses then the flanges outwardly and the
valve flap over the space between the flanges.

Improvements in and connected with Pneumatic Tyres
for Cycles.
I, GUSTAV HILLER of Lessingstr. 8, Zittau, Kingdom of Saxony, Germany,
Gentleman 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 present invention relates to a fastening-device for wheel-tyres consisting only
of one cover, distinguished by its simpleness and reliability and because in case of
damage the cover can be easily and well repaired.
The tyre is peculiar for consisting only of one cover and being cut open all along,
towards the rim of the wheel. The edges thus obtained are provided with flanges
going all round. With these flanges the tyre is placed into a rim of which the
section gets narrower at one point. The flanges are then by some means or other
expanded so as to closely fit to the inner wall of the rim. The tire being thus
tightly held is prevented from slipping.
In the annexed drawing the Figures 1-9 show in cross sections several
modifications of the present invention.
In Figure 1 the flanges a bare inserted into the rim c and placed over a rubber
tube d. By inflating this rubber tube & the flanges a bare expanded and by this
means secured to the rim c.
In Figure 2 the flanges a bare pressed together by elastic rings k k.
In Figure 3 and 4 the rubber tube d is inserted into the joint formed between the
flanges a b.
In Figure 5 the flanges a bare elastic rings of triangular cross section and are
pressed together by their own elasticity, the rim c having also triangular cross-
section.
b
In Figure 6 a thin flap attached to the flange 6 serves as a valve and aids to
maintain the air-pressure within the tire.
In Figure 7 the construction shown by Figure 5 is combined with a separate
elastic ring k.
In Figure 8 the joint between the flanges a and b is under the pressure of an
inflated elastic tube e.
In Figure 9 to the flanges a bare fastened thin flaps fƒ forming one piece but
having slots. These slots i are closed by metal straps 9 and screws h. After
opening the slots these latter allow free access to the interior of the tyre. Also
in the other modifications described, the cover being cut open all along the tyre
can be easily and durably repaired. There may be 3 to 6 slots or pockets i on the
inner circumference of the tyre. The straps 9 clamping together the meeting edges
of the flaps are only as long as the slots i.
Formerly, when the tyre was damaged, it could be repaired only by a plaster
being put on from outside. The present tyre however is for this purpose simply
opened and the plaster is applied inside the tyre. Thus the plaster is not only
protected against damage but is also pressed by the interior air-pressure against the
damaged place.
After attaching the tyre by one of the modified devices to the rim, the open tyre
can be inflated directly.
I am aware of the Patents of Leopold Holt numbered 13076 of 1891 and 14172
of 1892 and make no claim for any invention or inventions described and claimed
in and by the said Patents.

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 :
1. In an open pneumatic tyre for cycles the elastic tube d arranged within the
rim c for expanding by its inflation the flanges a b against the rim, as set forth.
2. In an open pneumatic tyre the elastic rings k for, pressing together the
flanges a b, as described.
3. In an open pneumatic tyre the flanges a b forming elastic rings of triangular
cross section in combination with the rim c of triangular cross section.
4. In combination with the flanges a the valve flap 1, as set forth.
5. In combination with the flanges a b the elastic tube e which inflated closes the
joint between the flanges a and b as set forth.
6. In combination with the flanges ab the flaps f with the slots i giving free
access to the interior of the rim, as set forth.
Dated this 25th day of August 1893.
