PROVISIONAL SPECIFICATION.
Improvements in Pneumatic Tires for Cycles and other Road
Vehicles.
We, ADOLPHUS ISIDOR RATH, and CHARLES HENRY BARSTOW, both of
58 Blackfriars Road, London, S.E. do hereby declare the nature of this invention to
be as follows:-
:-
This invention for improvements in pneumatic tires for cycles and other road
vehicles relates to tires in which the outer cover is provided at each of its two
sides with a sheath containing a wire by which it is retained in the rim of the wheel,
the said wire forming a complete circle within the sheath and having overlapping
ends.
In a pneumatic tire constructed according to this invention, one of the free ends
of each wire is secured so that it cannot move relatively to the outer cover preferably
within the sheath and the other end projects a short distance from the sheath and is
adapted to be secured so that the circle within the sheath shall be of the desired
diameter.
One way of securing the one end relatively to the cover is to stitch it tightly for
several inches in the sheath. Another way is to flatten the end and punch it with
one or more holes by which it is stitched to the outer cover. Another way is to
secure it to a metal plate fixed to the outer cover, or its end may be bent over and
passed through the sheath and through a hole in the bottom of the rim.
One way of securing the free end of the wire so that the circle within the sheath
shall be of the desired diameter is to make it L-shaped with a bulb end and pass it
through a hole in the side of the rim or it may be passed through the rim radially
or otherwise and be secured by a nut or it may be held by a lever so that it can be
pulled up tight. Another way is to secure a plate to the outer cover in which the
headed end of the wire can be inserted and held or a projection may be secured near
the fixed end of the wire and project through the sheath and serve to secure the
free end of the wire.
A great advantage of this construction is that only one end of the wire moves in
the sheath, and a further advantage is that the amount of free movement of this end
can be limited to the exact amount actually required in practice.

DIECIFICATION
Improvements in Pneumatic Tires for Cycles and other Road
Vehicles.
We, ADOLPHUS ISIDOR RATH, and CHARLES HENRY BARSTOW, both of
58 Blackfriars Road, London, S.É. 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 :-
This invention for improvements in pneumatic tires for cycles and other road
ID 071

page_text: vehicles relates to tires in which the outer cover is provided at each of its two sides
with a sheath containing a wire by which it is retained in the rim of the wheel,
the said wire forming a complete circle within the sheath and having overlapping
ends.
In a pneumatic tire constructed according to this invention, one of the free ends
of each wire is secured so that it cannot move relatively to the outer cover preferably
within the sheath, and the other end projects a short distance from the sheath and
is adapted to be secured so that the circle within the sheath shall be of the desired
diameter.
One way of securing the one end relatively to the cover is to stitch tightly for
several inches in the sheath. Another way is to flatten the end and punch it with one
or more holes by which it is stitched to the outer cover. Another way is to
secure it to a metal plate fixed to the outer cover, or its end may be bent over and
passed through the sheath and through a hole in the bottom of the rim.
One way of securing the free end of the wire so that the circle within the
sheath shall be of the desired diameter is to make it L-shaped with a bulb end
and pass it through a hole in the side of the rim or it may he passed through
the rim radially or otherwise and be secured by a nut or it may be held by a
lever so that it can be pulled up tight. Another way is to secure
a plate to the
outer cover in which the headed end of the wire can be inserted and held or a
projection may be secured near the fixed end of the wire and project through the
sheath and serve to secure the free end of the wire.
A great advantage of this construction is that only one end of the wire moves in
the sheath and a further advantage is that the amount of free movement of this end
can be limited to the exact amount actually required in practice.
In the accompanying sheet of illustrative drawings Fig. 1 is a part elevation of
a tire partly removed from the rim and showing the overlapping ends of the wire,
and Fig. 2 is a similar view with the outer cover in position and inflated.
The outer cover a is provided on each side with a sheath b which contains
the wires c.
One free end d of each wire is L-shaped and is secured to the outer
cover a by being stitched tightly in the sheath at e.
The other end of the wire c slightly overlaps the end d and is prevented from
crossing the same by the stitches f which keep the two wires in their relative
places in the sheath. This extreme end projects a short distance out of the sheath
and its end is hooked.
When placing the cover in position, the L-end d of one wire is passed through
the hole in the bottom of the rim and secured by a nut m.
The other end is
pushed into the sheath to allow of this edge of the cover passing over the rim
and is then drawn up and hooked into the hole g in the side of the rim.
The air tube is next inserted and then the other edge of the cover is secured in a
similar manner to the first so that the cover is mechanically held to the rim. On
inflating the air tube the whole tire is immovably fixed in position in the rim..
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 a pneumatic tire securing the edge of a cover to the rim of a wheel by
means of a wire received in a sheath in the edge of the cover and having one end
secured in the sheath and the other end free to be pushed into the sheath.
2. The improvements in pneumatic tires for wheels substantially as described with
reference to the drawings.
